The clamp receiver bore is configured to receive the clamp to fix the position of the workpiece.
Description
BACKGROUND

The present disclosure relates generally to workpiece securement systems. In particular, workpiece securement systems in the form of work tables are described.


Known workpiece securement systems are not entirely satisfactory for the range of applications in which they are employed. For example, existing workpiece securement systems typically have tabletops with round holes defining threaded ports for mounting blocks and clamps to the table. Round holes with threaded ports suffer from a number of drawbacks. For example, round threaded ports are difficult to repair, inaccurate, and unergonomic. Weld splatter is prone to stick to the threads in the ports and render the threads inoperable and/or require maintenance to address the corrupted threads. The round holes do not adequately resist rotational movement of hardware used to secure parts in position, which limits how accurately parts can be clamped in position.


Another limitation of conventional steel tables that are used to secure parts is that they rely on threaded studs and bolts to secure pieces to the table. Threaded studs and bolts are tedious to use because of all the twisting they require to secure them. Threaded studs and bolts tend to be less accurate than desirable because the significant torque needed to secure them tends to move the block, clamp, and/or piece being secured by them.


Conventional flat tables configured to mount parts for welding are labor and time intensive to use. One reason existing tables are labor and time intensive is because all the threaded fasteners take time and effort to use. Further, significant time and labor is necessary to repair known tables when weld splatters onto threaded ports. The tendency for conventional tables to not hold parts in position accurately requires more time and labor to readjust the position of the parts and/or to redo or repair an inaccurate weld resulting from the inaccurate position in which the part was secured.


Existing welding tables are a fixed size and unitary, which limits their applicability and increases costs for the end user. It is common for a machine shop to require larger welding tables over time as they receive requests to work on larger parts. A fixed size welding table limits the size of part that machine shops can handle. The fixed size of conventional weld tables forces machine shops to replace the tables outright with new, larger tables when larger tables are needed, which is a significant expense and wasteful. Further, shipping large, fixed size, unitary weld tables is cumbersome and expensive.


Another drawback of conventional weld tables is that they do not incorporate power supplies to conveniently power lights and tools. When working on a weld table, a user often uses power tools and needs good lighting to work accurately. With existing tables, the user must position the table close to a power supply or use extension cords to bring power near the table. Neither scenario is ideal as the former limits where the table may be positioned and the latter creates clutter and trip hazards.


Thus, there exists a need for workpiece securement systems that improve upon and advance the design of known workpiece securement systems. Examples of new and useful workpiece securement systems relevant to the needs existing in the field are discussed below.

SUMMARY

The present disclosure is directed to workpiece securement systems for securing a workpiece in a desired position with a clamp. The workpiece securement systems include a worktable, an anchor, a shelf, and a block. The worktable includes a leg and a tabletop. The leg supports the worktable from the ground.


The tabletop is supported by the leg and includes a top surface facing away from the ground and a bottom surface facing the ground. The tabletop defines a plurality of shaped openings extending through the tabletop from the top surface to the bottom surface.


The anchor is disposed in a selected shaped opening of the plurality of shaped openings and is configured to threadingly engage a bolt. The shelf is configured to selectively couple to the tabletop in a desired position and to support the anchor from below the bottom surface of the tabletop in a position where the anchor extends through the selected shaped opening.


The block is supported on the top surface of the tabletop and secured in a selected position on the tabletop by selectively coupling with the anchor. The block defines a mount bore and a clamp receiver bore. The mount bore extends through the block and is aligned with the anchor.


The bolt passing through the mount bore and threadingly engaging with the anchor secures the position of the block on the top surface of the tabletop. The clamp receiver bore is configured to receive the clamp to fix the position of the workpiece.


In some examples, the workpiece securement system includes a shim. In selected examples, the workpiece securement system includes a bin. In selected examples, the workpiece securement system includes an electrical system. In some examples, the workpiece securement system includes an illumination device.

DETAILED DESCRIPTION

The disclosed workpiece securement systems will become better understood through review of the following detailed description in conjunction with the figures. The detailed description and figures provide merely examples of the various inventions described herein. Those skilled in the art will understand that the disclosed examples may be varied, modified, and altered without departing from the scope of the inventions described herein. Many variations are contemplated for different applications and design considerations; however, for the sake of brevity, each and every contemplated variation is not individually described in the following detailed description.


Throughout the following detailed description, examples of various workpiece securement systems are provided. Related features in the examples may be identical, similar, or dissimilar in different examples. For the sake of brevity, related features will not be redundantly explained in each example. Instead, the use of related feature names will cue the reader that the feature with a related feature name may be similar to the related feature in an example explained previously. Features specific to a given example will be described in that particular example. The reader should understand that a given feature need not be the same or similar to the specific portrayal of a related feature in any given figure or example.


Definitions

The following definitions apply herein, unless otherwise indicated.


“Substantially” means to be more-or-less conforming to the particular dimension, range, shape, concept, or other aspect modified by the term, such that a feature or component need not conform exactly. For example, a “substantially cylindrical” object means that the object resembles a cylinder, but may have one or more deviations from a true cylinder.


“Comprising,” “including,” and “having” (and conjugations thereof) are used interchangeably to mean including but not necessarily limited to, and are open-ended terms not intended to exclude additional elements or method steps not expressly recited.


Terms such as “first”, “second”, and “third” are used to distinguish or identify various members of a group, or the like, and are not intended to denote a serial, chronological, or numerical limitation.


“Coupled” means connected, either permanently or releasably, whether directly or indirectly through intervening components.


Workpiece Securement Systems


With reference to the figures, workpiece securement systems will now be described. The workpiece securement systems discussed herein function to secure workpieces in a desired position and orientation for welding and other operations in a fast, ergonomic, and accurate way.


The reader will appreciate from the figures and description below that the presently disclosed workpiece securement systems address many of the shortcomings of conventional workpiece securement systems. For example, the workpiece securement systems described herein do not rely on round holes defining threaded ports for mounting blocks and clamps to the table, but instead use shaped openings. The shaped openings are easier to repair, more accurate, and more ergonomic than round holes in conventional weld tables. Weld splatter is much less of a hazard with the workplace securement systems described below. The shaped openings better resist rotational movement of hardware used to secure parts in position, which allows the user to more accurately secure parts in position.


The workpiece securement systems below improve over conventional weld tables by not relying merely on threaded studs and bolts to secure pieces to the table. The systems below avoid the tedium associated with twisting a large number of threaded studs and bolts. By providing an alternative to threaded studs and bolts, the systems below are more accurate because the user does not need to apply significant torque to secure the pieces into place, which would tend to undesirably move the piece being secured.


The workpiece securement systems described herein are less labor and time intensive to use than conventional systems. Reduced time and labor is necessary with the systems below because they avoid the threaded fasteners of conventional systems. Significant time and labor is saved with the systems below by avoiding the need to repair threaded ports when weld splatters onto them as regularly occurs with conventional systems. Another source of time and labor savings results from holding parts in position more accurately and with less attention and effort required. The more accurate positioning of the parts with the systems below enables the user to more accurately and consistently weld parts without errors needing corrections.


Another improvement over existing welding tables is the modular nature of the systems below. By allowing the user to readily expand the size of the system without discarding the existing system, the systems below are more flexible and reduce costs for the end user. Not needing to replace the system outright when larger systems are needed is a significant cost saver and reduces waste. Shipping the modular systems below is more convenient and less expensive as well.


The systems described below incorporate electrically isolated power supplies to conveniently power lights and tools. With the systems below, the user can more flexibly position the system and reduce clutter and trip hazards.


Workpiece Securement System


With reference to FIGS. 1-9, a workpiece securement system 100 will now be described as a first example of a workpiece securement system. As shown in FIG. 1, workpiece securement system 100 functions to secure a workpiece 101 in a desired position with a clamp 102.


As depicted in FIGS. 1-9, workpiece securement system 100 includes a worktable 103, an anchor 109, a shelf 111, a block 112, and a shim 120. In other examples, the workpiece securement system includes fewer components than depicted in the figures, such as not including a block or a shim. In certain examples, the workpiece securement system includes additional or alternative components than depicted in the figures, such as a bin, an electrical system, and an illumination device.


Worktable


Worktable 103 functions to provide a worksurface for working on workpieces. More particularly, worktable 103 cooperates with other components of system 100 to secure workpieces in desired positions.


As depicted in FIGS. 1-8, worktable 103 includes a leg 104 a tabletop 105, a second tabletop 132, a skirt 128, a spacer 136, a boundary anchor 138, and a bridge bracket 139. Other worktable examples include fewer and additional components.


For example, some worktable examples do not include a second tabletop, a skirt, a spacer, a boundary anchor, or a bridge bracket. Examples with a single tabletop may be considered a single modular unit of the workpiece securement system.


As shown in FIG. 10, the worktable may include more than two tabletops. As described in more detail below, the tabletops are modularly designed to enable two, three, or four or more tabletops to be secured together to increase the worksurface provided by the worktable.


Leg


With reference to FIGS. 1, 4 and 5, leg 104 supports worktable 103 from the ground.


In the present example, leg 104 is a tubular member was a base configured to be bolted to the ground, if desired. In some examples, the leg includes casters coupled to the base or in place of the base. As shown in FIGS. 1-6, leg 104 defines shaped openings that are configured the same as the shaped openings 108.


The leg may be any currently known or later developed type of leg. The reader will appreciate that a variety of leg types exist and could be used in place of the leg shown in the figures. In addition to the types of legs existing currently, it is contemplated that the workpiece securement systems described herein could incorporate new types of legs developed in the future.


The size of the leg may be varied as needed for a given application. In some examples, the leg is larger relative to the other components than depicted in the figures. In other examples, the leg is smaller relative to the other components than depicted in the figures. Further, the reader should understand that the leg and the other components may all be larger or smaller than described herein while maintaining their relative proportions.


In the example shown in FIGS. 1-9, worktable 103 includes four legs. However, the number of legs in the workpiece securement system may be selected to meet the needs of a given application. The reader should understand that the number of legs may be different in other examples than is shown in the figures. For instance, some workpiece securement system examples include additional or fewer legs than described in the present example.


In the present example, leg 104 is composed of steel. However, the leg may be composed of any currently known or later developed material suitable for the applications described herein for which it is used. Suitable materials include metals, polymers, ceramics, wood, and composite materials.


The shape of the leg may be adapted to be different than the specific examples shown in the figures to suit a given application. For example, the leg may include a face having the shape of a regular or irregular polygon, such as a circle, oval, triangle, square, rectangle pentagon, and the like. Additionally or alternatively, the leg may include a face having an irregular shape. In three dimensions, the shape of the leg may be a sphere, a pyramid, a cone, a cube, and variations thereof, such as a hemisphere or a frustoconical shape.


Tabletop


The role of tabletop 105 and second tabletop 132 is to provide a worksurface for working on workpieces. More particularly, tabletop 105 and second tabletop 132 cooperate with other components of system 100 to secure work-pieces in desired positions.


In the example shown in FIGS. 1-9, worktable 103 includes two tabletops, tabletop 105 and second tabletop 132. The reader can see in FIGS. 1-9 and in FIG. 10 as well that the tabletops are modularly designed to enable additional tabletops to be added to the worktable as needed. In some examples the worktable includes a single tabletop. In other examples, the worktable includes two tabletops, such as shown in FIGS. 1-9, three tabletops, four tabletops as shown in FIG. 10, or more than four tabletops.


The reader can see in FIGS. 1-4 and 6 that second tabletop 132 is coupled to tabletop 105 along lateral edge 133 of tabletop 105. Lateral edge 133 defines a boundary opening 137.


Given the modular nature of the tabletops, the discussion below will primarily describe tabletop 105 in detail. The reader should recognize that second tabletop 132 and any additional modular tabletops may be configured similarly or identically. As depicted in FIGS. 1-6, second tabletop 132 is configured the same as tabletop 105 in the present example.


The tabletops are configured to secure together to increase the worksurface provided by the worktable. Tabletop 105 and second tabletop 132 are welded together at defined interlock locations 160 shown in FIG. 8. Additionally, but optionally, FIG. 9 depicts the tabletops secured together with a bolt coupled to a boundary anchor 138 disposed in a boundary opening 137 of tabletop 105. With further reference to FIG. 9, the reader can see a spacer 136 disposed between tabletop 105 and second tabletop 132 to define the spacing between them. FIGS. 2, and 4-6 depict bridge bracket 139 reinforcing and providing rigidity to the union of tabletop 105 and second tabletop 132.


With reference to FIGS. 1-6, tabletop 105 is supported by legs 104. Tabletop 105 includes a top surface 106 facing away from the ground and a bottom surface 107 facing the ground. As can be seen in FIGS. 1-9, tabletop 105 defines a plurality of shaped openings 108 extending through tabletop 105 from top surface 106 to bottom surface 107.


In the present example, the tabletops are each 24 inches wide. However, the size of the tabletop may be varied as needed for a given application. In some examples, the tabletop is larger relative to the other components than depicted in the figures. In other examples, the tabletop is smaller relative to the other components than depicted in the figures. Further, the reader should understand that the tabletop and the other components may all be larger or smaller than described herein while maintaining their relative proportions.


In the present example, tabletop 105 is composed of steel. However, the tabletop may be composed of any currently known or later developed material suitable for the applications described herein for which it is used. Suitable materials include metals, polymers, ceramics, wood, and composite materials.


The shape of the tabletop may be adapted to be different than the specific examples shown in the figures to suit a given application. For example, the tabletop may include a face having the shape of a regular or irregular polygon, such as a circle, oval, triangle, square, rectangle pentagon, and the like. Additionally or alternatively, the tabletop may include a face having an irregular shape.


Shaped Openings


The shaped openings receive components of workpiece securement system 100, such as anchor 109 and shelf 111, and help secure those components in position.


As shown in FIGS. 7 and 8, the shaped openings complement the shape of anchor 109 to restrict anchor 109 from rotating about a vertical axis when disposed within a shaped opening. The reader can see in FIGS. 1-3 and 6-8 that the shaped openings define radius reliefs to facilitate forming the shaped openings utilizing CNC manufacturing techniques. However, the shape of the openings may be adapted to be different than the specific examples shown in the figures to suit a given application.


The reader can see in FIGS. 3, 7, and 8 that a first shaped opening 124 is longitudinally adjacent to a second shaped opening 125. As depicted in FIGS. 3, 7 and 8, first shaped opening 124 is laterally adjacent to a third shaped opening 150.


As depicted in FIG. 3, the lateral spacing between laterally adjacent shaped openings on tabletop 105 defines a common spacing dimension 134. The reader can see in FIG. 3 that the lateral spacing between shaped openings of tabletop 105 proximate lateral edge 133 of tabletop 105 and shaped openings of second tabletop 132 proximate lateral edge 133 of tabletop 105 defines an adjacent spacing dimension 135. In the example shown in FIGS. 1-9, adjacent spacing dimension 135 equals common spacing dimension 134 for uniformity and conceptual seamlessness between modular tabletops. However, the adjacent spacing dimension and the common spacing dimension may be different in some examples.


The size of the shaped openings may be varied as needed for a given application. In some examples, the shaped openings are larger relative to the other components than depicted in the figures. In other examples, the shaped openings are smaller relative to the other components than depicted in the figures. Further, the reader should understand that the shaped openings and the other components may all be larger or smaller than described herein while maintaining their relative proportions.


In the present example, tabletop 105 defines a plurality of shaped openings 108. The number of shaped openings in the workpiece securement system may be selected to meet the needs of a given application. The reader should understand that the number of shaped openings may be different in other examples than is shown in the figures. For instance, some workpiece securement system examples include additional or fewer shaped openings than described in the present example.


Spacer


Spacer 136 functions to establish adjacent spacing dimension 135 between tabletop 105 and second tabletop 132. As shown in FIGS. 3, 6 and 9, spacer 136 is configured to mount to lateral edge 133 of tabletop 105 between tabletop 105 and second tabletop 132.


In the present example, spacer 136 is a hexagonal nut. However, the shape of the spacer may be adapted to be different than the specific examples shown in the figures to suit a given application. For example, the spacer may include a face having the shape of a regular or irregular polygon, such as a circle, oval, triangle, square, rectangle pentagon, and the like. Additionally or alternatively, the spacer may include a face having an irregular shape. In three dimensions, the shape of the spacer may be a sphere, a pyramid, a cone, a cube, and variations thereof, such as a hemisphere or a frustoconical shape.


As shown in FIGS. 3 and 6, workpiece securement system 100 includes four spacers. However, the number of spacers in the workpiece securement system may be selected to meet the needs of a given application. The reader should understand that the number of spacers may be different in other examples than is shown in the figures. For instance, some workpiece securement system examples include additional or fewer spacers than described in the present example.


In the example shown in FIGS. 1-9, spacer 136 is selected to provide a desired adjacent spacing dimension 135 between tabletop 105 and second tabletop 132. However, the size of the spacer may be varied as needed for a given application. In some example, the spacer is larger relative to the other components than depicted in the figures. In other example, the spacer is smaller relative to the other component than depicted in the figures. Further, the reader should understand that the spacer and the other component may all be larger or smaller than described herein while maintaining their relative proportions.


The spacer may be any currently known or later developed type of spacer. The reader will appreciate that a variety of spacer types exist and could be used in place of the spacer shown in the figures. In addition to the types of spacers existing currently, it is contemplated that the workpiece securement systems described herein could incorporate new tees of spacers developed in the future.


In the present example, spacer 136 is composed of metal. However, the spacer may be composed of any currently known or later developed material suitable for the applications described herein for which it is used. Suitable materials include metals, polymers, ceramics, wood, and composite materials.


Boundary Anchor


As depicted in FIG. 9, boundary anchor 138 is selectively coupled to spacer 136 to support spacer 136 between tabletop 105 and second tabletop 132. The reader can see in FIG. 9 that boundary anchor 138 is complementarily configured with boundary opening 137 and is disposed in boundary opening 137.


Another function of boundary anchor 138 is to selectively secure block 112 to skirt 128 when disposed in a selected skirt shaped opening 129. Securing block 112 to skirt 128 extends the worksurface of tabletop 105 by having block 112 extend beyond the periphery of tabletop 105. By mounting blocks to skirt 128, the user can secure clamps to blocks in positions beyond the periphery of tabletop 105 when needed.


In the present example, boundary anchor 138 is composed of metal. However, the boundary anchor may be composed of any currently known or later developed material suitable for the applications described herein for which it is used. Suitable materials include metals, polymers, ceramics, wood, and composite materials.


In the present example, workpiece securement system 100 includes four boundary anchors. However, the number of boundary anchors in the workpiece securement system may be selected to meet the needs of a given application. The reader should understand that the number of boundary anchors may be different in other examples than is shown in the figures. For instance, some workpiece securement system examples include additional or fewer boundary anchors than described in the present example.


The shape of the boundary anchor may be adapted to be different than the specific examples shown in the figures to suit a given application. For example, the boundary anchor may include a face having the shape of a regular or irregular polygon, such as a circle, oval, triangle, square, rectangle pentagon, and the like. Additionally or alternatively, the boundary anchor may include a face having an irregular shape. In three dimensions, the shape of the boundary anchor may be a sphere, a pyramid, a cone, a cube, and variations thereof, such as a hemisphere or a frustoconical shape.


The size of the boundary anchor may be varied as needed for a given application. In some examples, the boundary anchor is larger relative to the other components than depicted in the figures. In other examples, the boundary anchor is smaller relative to the other components than depicted in the figures. Further, the reader should understand that the boundary anchor and the other components may all be larger or smaller than described herein while maintaining their relative proportions.


Bridge Bracket


As depicted in FIGS. 2 and 4-6, bridge bracket 139 couples tabletop 105 to second tabletop 132 and structurally reinforces the coupling. Bridge bracket 139 couples to tabletop 105 proximate bottom surface 107 and to second tabletop 132. As shown perhaps most clearly in FIGS. 2 and 5, bridge brackets 139 are organized into bracket pairs 170 comprised of two bridge brackets 139 coupled together with tie members 171 extending through slots 172 defined in bridge brackets 139.


In the present example, workpiece securement system 100 includes four bridge brackets. However, the number of boundary anchors in the workpiece securement system may be selected to meet the needs of a given application. The reader should understand that the number of boundary anchors may be different in other examples than is shown in the figures. For instance, some workpiece securement system examples include additional or fewer boundary anchors than described in the present example.


In the present example, bridge brackets 139 are composed of metal. However, the bridge brackets may be composed of any currently known or later developed material suitable for the applications described herein for which it is used. Suitable materials include metals, polymers, ceramics, wood, and composite materials.


The shape of the bridge brackets may be adapted to be different than the specific examples shown in the figures to suit a given application. Further, the size of the bridge brackets may be varied as needed for a given application. In some examples, the bridge brackets is larger relative to the other components than depicted in the figures. In other examples, the bridge brackets is smaller relative to the other components than depicted in the figures. Further, the reader should understand that the bridge brackets and the other components may all be larger or smaller than described herein while maintaining their relative proportions.


Skirt


Skirt 128 functions to provide a vertical surface with which to mount accessory items, such as a bin. The vertical surface of skirt 128 additionally or alternatively functions to couple together modular tabletops.


With reference to FIGS. 1-8, skirt 128 extends transversely from tabletop 105 toward the ground. As shown in FIGS. 1-8, skirt 128 defines a plurality of skirt shaped openings 129.


In the present example, skirt 128 is composed of metal. However, the skirt may be composed of any currently known or later developed material suitable for the applications described herein for which it is used. Suitable materials include metals, polymers, ceramics, wood, and composite materials.


The size of the skirt may be varied as needed for a given application. In some examples, the skirt is larger relative to the other components than depicted in the figures. In other examples, the skirt is smaller relative to the other components than depicted in the figures. Further, the reader should understand that the skirt and the other components may all be larger or smaller than described herein while maintaining their relative proportions.


Skirt Shaped Openings


Skirt shaped openings 129 serve to receive components of workpiece securement system 100, such as boundary anchor 138, and help secure those components in position.


The reader can see in FIGS. 1-8 that skirt shaped openings 129 are the same size and shape as shaped openings 108 for consistency and uniformity. However, the skirt shaped openings may be different sizes or shapes than the shaped openings in other examples.


The size of the skirt shaped openings may be varied as needed for a given application. In some examples, the skirt shaped openings are larger relative to the other components than depicted in the figures. In other examples, the skirt shaped openings are smaller relative to the other components than depicted in the figures. Further, the reader should understand that the skirt shaped openings and the other components may all be larger or smaller than described herein while maintaining their relative proportions.


The number of skirt shaped openings in the workpiece securement system may be selected to meet the needs of a given application. The reader should understand that the number of skirt shaped openings may be different in other examples than is shown in the figures. For instance, some workpiece securement system examples include additional or fewer skirt shaped openings than described in the present example.


Anchor


Anchor 109 serves to retain blocks 112 in a desired position on worktable 103. As shown in FIGS. 7 and 8, anchor 109 is disposed in a selected shaped opening of plurality of shaped openings 108 and is configured to threadingly engage a bolt 110. Anchor 109 is configured to not rotate within shaped opening 108 despite torque being applied to bolt 110. Anchor 109 laterally abutting the edges of shaped opening 108 restricts anchor 109 from rotating in response to applied torque. As depicted in FIGS. 7 and 8, anchor 109 is supported on floor 123 of shelf 111.


The reader can see in FIGS. 7 and 8 that anchor 109 defines a tee slot nut 115. In other examples, the anchor is configured differently than a tee slot nut.


Anchor 109 being disposed below the surface of tabletop 105 conceals the mounting hardware from view above the tabletop. This provides a cleaner worksurface and protects the mounting hardware from weld splatter.


The shape of the anchor may be adapted to be different than the specific examples shown in the figures to suit a given application. In many, but not necessary all examples, the size and shape of the anchor will complement the size and shape of the shaped openings.


The size of the anchor may be varied as needed for a given application. In some examples, the anchor is larger relative to the other components than depicted in the figures. In other examples, the anchor is smaller relative to the other components than depicted in the figures. Further, the reader should understand that the anchor and the other components may all be larger or smaller than described herein while maintaining their relative proportions.


The number of anchors in the workpiece securement system may be selected to meet the needs of a given application. The reader should understand that the number of anchors may be different in other examples than is shown in the figures. For instance, some workpiece securement system examples include additional or fewer anchors than described in the present example.


In the present example, anchor 109 is composed of metal. However, the anchor may be composed of any currently known or later developed material suitable for the applications described herein for which it is used. Suitable materials include metals, polymers, ceramics, wood, and composite materials.


Bolt


The role of bolt 110 is to selectively couple block 112 to anchor 109 by passing through mount bore 113 of block 112. The bolt may be any currently known or later developed type of bolt. The reader will appreciate that a variety of bolt types exist and could be used in place of the bolt shown in the figures. In addition to the types of bolts existing currently, it is contemplated that the workpiece securement systems described herein could incorporate new type of bolts developed in the future.
