The present disclosure relates generally to a rotation device for a workpiece and more particularly to a rotation device for rotating a long, irregularly shaped workpiece (e.g., an aerodynamic structure of an aircraft).
Some manufactured parts are long and have irregular shapes. During and after manufacturing of the manufactured parts, the manufactured parts may need to be rotated to provide access to one or more surfaces for further processing, for inspection (e.g., visual inspection or inspection by one or more imaging devices), or both. To rotate some long workpieces, a crane is used to lift and turn the workpiece while the workpiece remains attached to the crane. Rotating a long workpiece using a crane can be labor intensive, time consuming, and can place unwanted forces on the workpiece that have potential to damage the workpiece. It is desirable to have a rotation device that alleviates the need for a crane, is portable, and can be used to rotate a workpiece in a short amount of time as compared to rotating the workpiece using a crane.
The present disclosure describes rotation devices and methods for handling and rotating workpieces, such as an aerodynamic structure of an aircraft. The apparatus and methods allow for rotation of workpieces that are long, irregularly shaped, fragile, or combinations thereof. The rotation devices are portable, are not labor intensive to use, are easy to manufacture and operate, and are less expensive and quicker than using methods of rotation that involve the use of a crane.
In a particular example, a rotation device to reposition a workpiece includes a retainer. The retainer includes a first structure and a second structure coupled to the first structure. The first structure includes two or more first arcuate members and a plurality of first workpiece supports. The second structure includes two or more second arcuate members and a plurality of second workpiece supports. The second structure is moveable relative to the first structure to place the retainer in an open configuration to receive the workpiece and is movable relative to the second structure to place the retainer in a closed configuration to retain the workpiece in the retainer. The one or more first arcuate members are in working relation to the one or more second arcuate members to define two or more ring segments when the retainer is in the closed position. The rotation device also includes a base. Retainer supports coupled to the base contact the two or more ring segments and enable the ring segments to move relative to the retainer supports to rotate the retainer.
In another particular example, a rotation device to reorient a workpiece includes a retainer. The retainer accepts the workpiece in an open configuration and retains the workpiece in a closed configuration. The retainer forms two or more ring segments in the closed configuration. The rotation device includes a base to support the retainer. The base includes a plurality of retainer supports in working relation to the two or more ring segments to enable rotation of the retainer from a first orientation where the first structure contacts the retainer supports to a second orientation where the second structure contacts the retainer supports.
In another particular example, a method of rotating a workpiece includes positioning a retainer of a rotation device relative to the workpiece such that first workpiece supports of a first structure of the retainer are in contact with a first surface of the workpiece. The method includes moving a second structure of the retainer relative to the workpiece to a closed configuration such that second workpiece supports of the second structure are in contact with a second surface of the workpiece. The first structure and the second structure form two or more ring segments in the closed configuration. The method also includes rotating the two or more ring segments via retainer supports to rotate the retainer.
The figures and the following description illustrate specific exemplary embodiments. It will be appreciated that those skilled in the art will be able to devise various arrangements that, although not explicitly described or shown herein, embody the principles described herein and are included within the scope of the claims that follow this description. Furthermore, any examples described herein are intended to aid in understanding the principles of the disclosure and are to be construed as being without limitation. As a result, this disclosure is not limited to the specific embodiments or examples described below, but by the claims and their equivalents.
Systems, apparatuses, and methods disclosed herein are directed to rotation of a workpiece using a rotation device. The workpiece is rotated to position the workpiece in a particular orientation to facilitate further processing of the workpiece, visual or instrument inspection of the workpiece, to facilitate orientation of the workpiece for assembly to another workpiece, to facilitate access to one or more particular surfaces of the workpiece during manufacturing of the workpiece, or for other purposes. The workpiece may be long, bulky, heavy, fragile, or combinations thereof. The rotation device is a portable device that eliminates the need to employ the use of a crane to rotate the workpiece.
Particular implementations are described herein with reference to the drawings. In the description, common features are designated by common reference numbers throughout the drawings. In some drawings, multiple instances of a particular type of feature are used. Although these features are physically and/or logically distinct, the same reference number is used for each. In some cases, the different instances are distinguished by addition of a letter to the reference number. When the features as a group or a type are referred to herein (e.g., when no particular one of the features is being referenced), the reference number is used without a distinguishing letter. However, when one particular feature of multiple features of the same type is referred to herein, the reference number is used with the distinguishing letter. For example, referring to
As used herein, various terminology is used for the purpose of describing particular implementations only and is not intended to be limiting. For example, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. Further, the terms “comprise,” “comprises,” and “comprising” are used interchangeably with “include,” “includes,” or “including.” Additionally, the term “wherein” is used interchangeably with the term “where.” As used herein, “exemplary” indicates an example, an implementation, and/or an aspect, and should not be construed as limiting or as indicating a preference or a preferred implementation. As used herein, an ordinal term (e.g., “first,” “second,” “third,” etc.) used to modify an element, such as a structure, a component, an operation, etc., does not by itself indicate any priority or order of the element with respect to another element, but rather merely distinguishes the element from another element having a same name (but for use of the ordinal term). As used herein, the term “set” refers to a grouping of one or more elements, and the term “plurality” refers to multiple elements.
Referring now to the drawings, and more particularly to
The retainer 104 includes a first structure 108 coupled to a second structure 110. In a particular implementation, the first structure 108 is hinged to the second structure 110 by one or more hinges 112 to enable the retainer 104 to be moved from the closed position (as depicted in
One or more shafts 114 extend between hinges 112. Manual power or one or more linear actuators (e.g., hydraulic or pneumatic actuators) are used to open and close the retainer 104. When manual power is used to open the retainer 104 to an open configuration, one or more rotation stops are engaged to maintain the retainer 104 in the open configuration. The one or more rotation stops are disengaged to enable the retainer 104 to move from the open configuration to a closed configuration.
The first structure 108 includes one or more arcuate members 116A, a plurality of workpiece supports 118A, and one or more structure members 120A. The second structure 110 includes one or more arcuate members 116B, a plurality of workpiece supports 118B, and one or more structure members 120B. In
When the first structure 108 is coupled to the second structure 110 to form the retainer 104 and the retainer 104 is in the closed position, arcuate members 116A of the first structure 108 and corresponding arcuate members 116B of the second structure 110 form ring segments 122. The ring segments 122 formed by corresponding arcuate members 116A, 116B form a cylindrically shaped framework with centers of the ring segments 122 formed by corresponding arcuate members 116A, 116B located along a central longitudinal axis of the cylindrical framework.
The ring segments 122 formed by corresponding arcuate members 116A, 116B are positioned on retainer supports 124 that are coupled to the base 106. The retainer supports 124 are rollers, pinion gears, chain links, or other components that contact the ring segments 122 formed by corresponding arcuate members 116A, 116B such that movement of the retainer supports 124 (e.g., rotation of the retainer supports 124) rotates the retainer 104. In an implementation, the retainer supports 124 are rollers that contact the ring segments 122 formed by corresponding arcuate members 116A, 116B such that rotation of the rollers causes the ring segments 122 to move relative to the rollers to rotate the retainer 104.
The workpiece supports 118 provide support for the workpiece 102 positioned in the retainer 104 between the first structure 108 and the second structure 110. The workpiece supports 118 are shaped or contoured to conform to one or more outer surfaces 126 of the workpiece 102 to be rotated by the rotation device 100. In the exemplary embodiment, when the workpiece 102 is embodied as a horizontal stabilizer for an aircraft, the outer surfaces 126 are contoured to conform to the outer surfaces of the horizontal stabilizer such that no damage occurs to the horizontal stabilizer while being installed into the rotation device or rotated by the rotation device 100. The workpiece supports 118 include padding 128, as depicted in
When the workpiece 102 is positioned in the retainer 104 and the retainer 104 is in the closed position, one or more latches 130 are used to couple the first structure 108 to the second structure 110 to inhibit the retainer 104 from opening as the workpiece 102 is rotated. For workpieces 102 having widths that extend out of the retainer 104, the one or more latches 130 have a u-shape to accommodate a width portion of the workpiece 102 that extends out of the retainer 104. In the implementation depicted in
The base 106 includes a sled 132, and supports 134. Axles 136 with the retainer supports 124 are coupled to the supports 134. The sled 132 includes wheels 138 to enable the rotation device 100 to be moved to a desired location. In an implementation, the sled 132 is coupled to rails that guide the rotation device 100 to or away from the workpiece 102. In some implementations the sled 132 includes a drive coupled to one or more of the wheels 138 that moves the sled 132. In other implementations, the sled 132 is manually positioned or positioned using a tow vehicle. When the sled 132 is in a desired location, a wheel lock mechanism is engaged to inhibit unintended movement of the sled 132.
The supports 134 support the axles 136, and the retainer 104 is supported on retainer supports 124 coupled the axles 136. In a particular implementation, as depicted in
In some implementation, heights of the supports 134 are adjustable to adjust a height of the retainer 104 relative to a floor 140. Enabling adjustment of the heights of the supports 134 enables the rotation device 100 to lift the workpiece 102 from fixed workpiece stands that support the workpiece 102. The supports 134 are coupled to a lift system (e.g., lift system 504 depicted in
When the workpiece 102 is positioned in the retainer 104 of the rotation device 100, portions of the workpiece 102 can extend out of the rotation device 100 (e.g., from one or more sides of the retainer 104, from a front of the retainer 104, or from combinations thereof). A center of mass of the workpiece 102 is located in the retainer 104 near a center point of the retainer 104.
In
When the second structure 110 is supporting the workpiece 102B, the first structure 108 of the rotation device 100 is moved to contact a second surface 508 of the workpiece 102B with the workpiece supports 118A of the first structure 108 to place the rotation device 100 in a closed configuration. If needed, one or more latches 130 are coupled to the first structure 108 and the second structure 110 to inhibit the rotation device 100 from opening during rotation of the retainer 104.
After rotation of the retainer 104 such that the workpiece 102B is oriented to reside on the workpiece stands 402, the rotation device 100 is moved between the workpiece stands 402 and the one or more latches 130 are removed from the first structure 108, the second structure 110, or both.
In some implementations, the retainer 104 is used to rotate the workpiece 102 from an original orientation by a particular number of degrees to place the workpiece 102 in a particular orientation. When the workpiece 102 is in the particular orientation one or more tasks can be performed on the workpiece 102 while the workpiece 102 is in the retainer 104. After the one or more tasks are completed, the retainer 104 is rotated back to the original orientation, to a different orientation, the lift system 504 is used to set the workpiece 102 on the workpiece stands 402, or combinations thereof.
Positioning the retainer 104 includes opening the retainer 104 to an open configuration to receive the workpiece 102.
The method 1200 includes, at 1204, moving the second structure 110 of the retainer 104 relative to the workpiece 102 to a closed configuration. In the closed configuration, the workpiece supports 118B of the second structure 110 contact a second surface 508 of the workpiece 102 (shown in
The method 1200 includes, at 1206, securing the first structure 108 to the second structure 110. In an implementation, securing the first structure 108 to the second structure 110 includes coupling the first structure 108 to the second structure 110 using one or more latches 130, as depicted in
The method 1200 includes, at 1208, rotating the ring segments 122 via retainer supports 124 to rotate the retainer 104.
The drive mechanism 510 is engaged to rotate the axle 136A that is fixed to one or more drive retainer supports 124A of the retainer supports 124. Rotation of the axle 136A rotates the drive retainer supports 124A and causes rotation of the retainer 104.
The method 1200 includes, at 1210, opening the retainer 104. Opening the retainer 104 includes uncoupling the one or more latches 130 from the first structure 108, the second structure 110, or both, and moving the first structure 108 relative to the second structure 110 to place the retainer 104 in the open configuration.
The method 1200 includes, at 1212, positioning the second surface 508 of the workpiece 102 on the workpiece stands 402. The supports 134 of the base 106 are lowered, or the workpiece stands 402 are raised, to position the second surface 508 of the workpiece 102 on the workpiece stands 402.
The rotation device 100 has a simple design and is relatively inexpensive to manufacture. The rotation device 100 is configured to handle a workpiece, such as a wing structure of an aircraft, a wind turbine blade, or other long workpieces that are difficult to rotate due to their length, weight, fragility, or combinations thereof. The workpiece 102 is rotated to position particular surfaces of the workpiece for additional processing, for inspection, or both. The rotation device 100 is portable, inexpensive and light weight relative to cranes and alternate equipment used to rotate long workpieces, and the rotation device 100 is able to accommodate heavy, irregularly shaped, and fragile workpieces.
