The present invention relates generally to a carpenter tool, and more particularly to a workpiece guiding device that enables quick adjustment of the selected tooling angle of the wooden workpiece in relation to the machining tool.
Circular sawing machines, band sawing machines, and wood milling machines are machines for cutting workpieces made of wood. A machine has a workbench. The workpiece is placed on the workbench. The workpiece is moved toward the working machining tool. The plurality of cutting blades of the machining tool cut the workpiece. The machining tool can be a circular saw, a band saw, or a milling cutter.
When the tooling machine carries out identical cutting operations for multiple workpieces of the same specification in a sequence, the workpieces must be placed on the workbench one after another, and individually align each workpiece to the machining tool. A fixture that guides the moving direction of the workpiece can enhance the working efficiency and tooling accuracy when executing repeated cutting operations.
The fixture is configured on the workbench. The fixture can move on the top of the workbench and be positioned. One side of the fixture is formed with an abutting surface. The fixture can be adjusted according to the tooling requirement, so that a specific relative angle and distance between the abutting surface and the machining tool can be formed. During the tooling operation, the workpiece placed on the workbench is pressed laterally against the abutting surface, and the workpiece is pushed toward the machining tool. The abutting surface guides the workpiece to move along a specific angle toward the machining tool.
When a fixture is configured on the workbench, an assisting fixture to fix the workpiece can be used. The assisting fixture is configure on the workbench and is laterally pressed against the abutting surface of the fixture. The assisting fixture is operated to move along the abutting surface. Thus, the fingers of the user do not need to touch and press the workpiece, and can be kept away from the machining tool. This can enhance safety when cutting the workpiece.
The assisting fixture to guide the movement direction of the workpiece comprises a bed plate, a long guiding component, two clamping structures and two pressing structures, wherein the bed plate is configured on top of the workbench, and is pressed laterally against the abutting surface of the fixture. The bed plate can slide back and forth along the abutting surface. The bed plate is used to load the workpiece. The guiding component is configured on top of the bed plate, and the guiding component can move on top of the bed plate. The clamping structures are used to clamp the bed plate and the guiding component, so as to position the guiding component. One side of the guiding component is formed with a vertical guiding surface. The guiding surface and the machining tool are parallel to each other or have a specific included angle. The pressing structure is configured on the guiding component. The pressing structure is used to press the workpiece placed on the bed plate from above, avoiding displacement of the workpiece during the tooling process under the force of the machining tool.
The workpiece is placed on top of the bed plate and is laterally pressed against the guiding surface. Based on the relative angle and distance between the guiding surface and the machining tool, the machining tool can cut the workpiece along a predetermined tooling path.
When both a fixture and an assisting fixture are used, the fixture or the guiding component of the assisting fixture can be adjusted as needed to change the tooling path of the machining tool.
To adjust the fixture or the guiding component, measuring tools or modules such as a scale or a gauge is required to measure the angle of the abutting surface or the guiding surface in relation to the machining tool. When the required tooling angle is met, usually a test tooling process is executed to confirm if the tooling angle satisfies the tooling requirement and to determine the accuracy during actual tooling. Based on the result of test tooling, the operator may conduct another adjustment or directly proceed to the tooling operation.
In most cases, the machining tool cuts the workpiece in a path parallel to the abutting surface. The angle between the machining tool and the workpiece is hereinafter called a tooling angle. A machining tool such as a circular saw or band saw can be used to cut the workpiece to form a vertical benchmark surface. There are less cases when the tooling path of the machining tool is required to be not parallel to the abutting surface. When it is required to change a regularly used tooling angle to other tooling angles, the abutting surface must undergo the above adjusting operations and another test tooling operation is required. When the fixture is needed to change from another tooling angle back to the regularly used tooling angle, the above adjusting operation and test tooling operation are also required. There are particularly frequent cases that require change of the tooling angle back to the regular angle. The aforesaid other tooling angles refer to a tooling angle other than the regularly used tooling angle, and is not limited to a specific angle.
The main object of the invention is to provide a workpiece guiding device.
The technical feature of the invention to solve the aforesaid problems lies in that the workpiece guiding device comprises:
According to the tooling requirement, the present invention can easily adjust the included angle to a specific angle without using angle measuring tools or modules such as protractors or angle gauges, and thus can enhance the convenience in adjusting the position of the supporting component at a regularly used tooling angle.
As shown in
The supporting component 30 is movably configured on the loading surface 22. The bottom of the supporting component 30 is formed with a second long slot 32. Specifically, the bottom of the supporting component 30 is formed with a bottom surface 31, and the bottom surface 31 is formed with a second long slot 32 facing upward. In the present embodiment, the bottom surface 31 is optionally abutted against the loading surface 22. Alternatively, the bottom surface 31 can also be not abutted against the loading surface 22. One side of the supporting component 30 is defined as the supporting side 33. The other side of the supporting component 30 is defined as the second opposite side 34. The supporting side 33 and the second opposite side 34 are respectively adjacent to the bottom surface 31. The supporting side 33 and the plane 60 intersect with each other. An included angle θ is formed between the supporting side 33 and the plane 60. The supporting side 33 is used to receive lateral abutting by the workpiece 90. The second long slot 32 extends to the second opposite side 34. The first long slot 24 and the second long slot 32 are opposite each other in the vertical direction, so that the base 20 and the supporting component 30 enclose a long first space 72. The radial section of the first space 72 is a quadrilateral.
The limiting component 40 is removably configured in the first space 72. The radial periphery of the limiting component 40 enters the first long slot 24 and the second long slot 32, so as to limit the included angle θ to avoid any change. The radial cross section of the limiting component 40 is square, matching the first space 72.
The clamping structures 50 respectively clamp the base 20 and the supporting component 30, so as to position the supporting component 30 to avoid any movement. The clamping structure 50 is prior art commonly known by those skilled in the art. Therefore, details of the clamping structures 50 are not described herein.
The base 20 can be used as the workbench or the bed plate disclosed in prior art. According to the tooling requirement, the limiting component 40 can be provided or removed. As shown in
When the limiting component 40 is removed, the supporting component 30 can be rotated to change the included angle θ according to the tooling requirement, to form other not commonly used tooling angles. The supporting component 30 can also be adjusted to the aforesaid regularly used tooling angle. When the limiting component 40 is not provided, the using state with the included angle θ being 90 degrees is not excluded.
The base 20 can be used as the workbench for the tooling machines disclosed in prior art. The supporting component 30 can be used as the fixture configured on the workbench as disclosed in prior art, so as to guide the movement of the workpiece 90, and to enhance working efficiency and tooling accuracy when executing multiple identical cutting operations.
The present invention can adjust the supporting component 30 to change the included angle θ. When changing from a tooling angle that is not frequently used to the regularly used tooling angle, the provision of the limiting component 40 enables easy adjustment of the included angle θ to be 90 degrees without using angle measuring tools or modules such as a protractor or an angle gauge. Based on the requirement for the tooling size, the user just need to adjust the position of the supporting component 30 in the tangential direction of the plane 60. This can help enhance the convenience in adjusting the position of the supporting component 30 at the regularly used tooling angle.
Optionally, the first long slot 24 extends to the first opposite side 26. The limiting component 40 can be configured or removed without the need to remove the supporting component 30 from the base 20.
Optionally, the supporting component 30 is formed with a stopping surface 35. The stopping surface 35 blocks the end of the limiting component 40 neighboring the supporting side 33, preventing the limiting component 40 from protruding out of the supporting side 33, so that the workpiece 90 cannot be pressed laterally against the supporting side 33.
As shown in
The operating shaft 42 can be controlled by the user to move the limiting component 40 along the direction of the first long slot 24, so as to insert the limiting component 40 into the first space 72 or extract the limiting component 40 from the first space 72, making the operation more convenient.

As shown in
As shown in
Embodiment 5 can be applied in cases where there are two regularly used tooling angles, and can enhance the convenience in adjusting the position of the supporting component 30 at any of the regularly used tooling angles.
As shown in
Embodiment 6 can be used together with any one from Embodiment 1 to Embodiment 5. As an option, Embodiment 6 can be configured on top of the workbench disclosed in prior art to work with the fixture.
