[0003] However, cylindrical or circumferentially rotating shell-shaped workpieces are difficult to clamp due to their smooth surfaces. Therefore, the methods for clamping and flipping them are relatively simple and cannot meet the requirements for multi-angle flipping during machining. If heavy workpieces need to be disassembled and reassembled multiple times to readjust the flipping direction during machining, the machining efficiency will be significantly reduced.

[0041] Reference Appendix Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the workpiece clamping and flipping device of this application clamping the workpiece; Figure 2 This is a perspective view of the workpiece clamping and flipping device of this application; the specific embodiments are described below in conjunction with the above-mentioned drawings.
[0042] Reference Appendix Figure 1 and Figure 2 This application provides a workpiece clamping and flipping device, including a mounting frame 100, two first clamping assemblies 200, two second clamping assemblies 300, and a third clamping assembly 400; wherein, the mounting frame 100 is hollow inside and has an opening at at least one end, the two first clamping assemblies 200 are disposed opposite to each other at both ends of the mounting frame 100, and the two first clamping assemblies 200 are used to clamp the workpiece and drive it to rotate around a first axis, the two second clamping assemblies 300 are disposed opposite to each other at the other ends of the mounting frame 100, and the two second clamping assemblies 300 are used to clamp the workpiece and drive it to rotate around a second axis, and the third clamping assembly 400 is disposed opposite to the opening, and the third clamping assembly 400 is used to clamp the workpiece and drive it to rotate around a third axis, the first axis and the second axis are perpendicular to each other and located in the same plane, and the third axis is perpendicular to the plane.
[0043] It should be noted that the relationship between the first axis, the second axis, and the third axis is equivalent to the relationship between the three coordinate axes in a standard three-axis spatial coordinate system. Any two axes are taken as reference planes, and the remaining axis is perpendicular to the reference planes. This allows the workpiece located in the mounting bracket 100 to rotate around the first axis, the second axis, and the third axis, thereby achieving a 360° rotation.
[0044] Reference Appendix Figure 1 In some embodiments, the mounting bracket 100 is hollow inside and has an opening at the top. The length and width of the opening are greater than the length and width of the workpiece, so that the workpiece can be loaded into the mounting bracket 100 from the top and clamped by a lifting device.
[0045] It should be noted that, in order to facilitate machining, the mounting frame 100 should also be provided with clearance openings according to the actual situation; in some embodiments, the side wall of the mounting frame 100 is also provided with multiple clearance openings to facilitate machining equipment to extend into the mounting frame 100 to perform machining on the workpiece.
[0046] Reference Appendix Figure 2 In some embodiments, two first clamping assemblies 200 are disposed opposite to each other at both ends of the mounting frame 100. The two first clamping assemblies 200 are used to clamp the workpiece and drive it to rotate around a first axis. The first clamping assembly 200 includes a first rotating member 201, a first clamping member 202 and a sliding seat 203. The first rotating member 201 is rotatably disposed on the mounting frame 100 around the first axis. At least three first clamping members 202 are slidably disposed on the first rotating member 201. The sliding seat 203 is slidably disposed on the mounting frame 100 along the first axis. The first rotating member 201 is rotatably disposed on the sliding seat 203 around the first axis.
[0047] Specifically, the two sliding seats 203 are slidably mounted on the mounting frame 100. When they are relatively far apart, the lifting equipment can control the workpiece to sink between the two sliding seats 203. When they are relatively close, the workpiece is clamped by the first clamping member 202. The first clamping member 202 clamps the two ends of the cylindrical workpiece by simultaneously moving closer to the axis center of the first rotating member 201, or the first clamping member 202 pushes and fixes the two ends of the hollow shell type workpiece by simultaneously moving away from the axis center of the first rotating member 201. After the first clamping member 202 is relatively fixed with the workpiece, the workpiece rotates relative to the sliding seat 203 through the rotational connection between the first rotating member 201 and the sliding seat 203.
[0048] It should be noted that the control methods for the relative sliding of the first clamping member 202 and the first rotating member 201, the relative rotation of the first rotating member 201 and the sliding seat 203, and the relative sliding of the sliding seat 203 and the mounting bracket 100 should be set according to the actual situation, including but not limited to automatic motor control and manual control.
[0049] Reference Appendix Figure 2 In some embodiments, two second clamping assemblies 300 are disposed opposite to each other at the other ends of the mounting frame 100. The two second clamping assemblies 300 are used to clamp the workpiece and drive it to rotate around the second axis. The second clamping assembly 300 includes a second rotating member and a second clamping member. One end of the second rotating member is rotatably disposed on the mounting frame 100 around the second axis, and the second clamping member is disposed at the other end of the second rotating member.
[0050] Specifically, the second clamping member is used to press against the outer surface of the workpiece to achieve the purpose of clamping and fixing, and the second rotating member is used to drive the workpiece fixed by the second clamping member to rotate relative to the mounting frame 100 around the second axis.
[0051] Reference Appendix Figure 1 and Figure 2 In some embodiments, the end of the second clamping member away from the second rotating member is provided with a curved surface, and the radius of curvature of the curved surface is greater than the radius of curvature of the workpiece surface.
[0052] Specifically, the second clamping member is provided with a curved surface based on the smooth surface of the workpiece, and the radius of curvature of the curved surface is greater than the radius of curvature of the workpiece surface. Even if the curvature of the curved surface is less than the curvature of the workpiece surface, the two relatively set curved surfaces can press and wrap the workpiece, thereby increasing the contact area between the second clamping member and the workpiece and preventing the workpiece from slipping during the flipping process.
[0053] In some embodiments, the second clamping assembly 300 further includes an adjusting member and a bearing member. The adjusting member is disposed between the second rotating member and the mounting frame 100 and is threadedly connected to the mounting frame 100. The bearing member is disposed between the second rotating member and the adjusting member, and the second rotating member is rotatably connected to the adjusting member through the bearing member.
[0054] Specifically, the adjusting member is threadedly connected to the mounting bracket 100, and the second rotating member is pushed toward the workpiece by rotating the adjusting member relative to the mounting bracket 100. The bearing member is used to support the relative rotation of the second rotating member and the adjusting member, so as to allow the workpiece to flip about the second axis relative to the mounting bracket 100.
[0055] Reference Appendix Figure 2 In some embodiments, the third clamping assembly 400 includes a third rotating member 401 and a third clamping member 402. The third rotating member 401 is rotatably mounted on the mounting bracket 100 about a third axis, and at least three third clamping members 402 are slidably mounted on the third rotating member 401.
[0056] Specifically, when the workpiece is placed on the third clamping assembly 400, the third clamping assembly 400 not only needs to clamp and fix the workpiece, but also needs to bear the weight of the workpiece; the three third clamping members 402 simultaneously move closer to the axial center of the third rotating member 401 to clamp the bottom end of the cylindrical workpiece, or the three third clamping members 402 simultaneously move away from the axial center of the third rotating member 401 to push and fix the bottom end of the hollow shell type workpiece. The third rotating member 401 is used to bear the weight of the workpiece and also to drive the workpiece to rotate relative to the mounting frame 100 around the third axis.
[0057] Reference Appendix Figure 1 and Figure 2 In some embodiments, the first axis is perpendicular to the second axis and lies in the same plane, and the third axis is perpendicular to the plane.
[0058] Specifically, the workpiece is inserted into the mounting frame 100 along its height direction through the top opening of the mounting frame 100. The two first clamping components 200 clamp both ends of the workpiece in the length direction and drive the workpiece to rotate around the first axis. The two second clamping components 300 clamp both ends of the workpiece in the width direction and release the workpiece by the two first clamping components 200, so that the two second clamping components 300 drive the workpiece to rotate around the second axis. After the workpiece is rotated 90° by the two second clamping components 300 and the axis of the workpiece is parallel to the third axis, one end of the workpiece in the length direction is clamped by the third clamping component 400 and the two second clamping components 300 release the workpiece, so that the third clamping component 400 drives the workpiece to rotate around the third axis.
[0059] In some embodiments, the distance between the two first clamping components 200 and the second clamping component 300 is equal to ensure that the distance between the two first clamping components 200 and the second clamping component 300 is equal. During the clamping position change process, the two second clamping components 300 clamp the middle part of the workpiece, thereby avoiding the workpiece slippage caused by uneven gravity at both ends during the process of the two second clamping components 300 driving the workpiece to flip.
[0060] In some embodiments, the distance between the first clamping component 200 and the third clamping component 400 is equal to the distance between the second clamping component 300 and the third clamping component 400, in order to ensure that the distances between the first clamping component 200 and the second clamping component 300 relative to the third clamping component 400 are equal, so as to keep the clamping position conversion process stable.
[0061] Reference Appendix Figure 1 and Figure 2In actual use, when it is necessary to rotate the workpiece around the first axis, the workpiece is lifted by the lifting equipment and lowered between the two first clamping components 200 through the opening on the mounting frame 100. By sliding the two sliding seats 203 toward the workpiece, the workpiece can be clamped and fixed by the two first clamping components 202, and the workpiece can be driven to rotate around the first axis by the two first rotating components 201, which facilitates machining.
[0062] When it is necessary to switch the workpiece from rotating around the first axis to rotating around the second axis, the two adjusting members are rotated to bring the two second clamping members closer to the workpiece and clamp it in place. The two sliding seats 203 are moved away from the workpiece to release the clamping of the first clamping assembly 200 on the workpiece. The two second rotating members and the two bearing members drive the workpiece to rotate around the second axis, which facilitates machining.
[0063] When it is necessary to switch the workpiece from rotating around the second axis to rotating around the third axis, the workpiece is flipped 90° by the second clamping assembly 300 so that the axis of the workpiece is parallel to the third axis. The workpiece is released by rotating the second adjusting member and slides down to the third clamping member 402 under the action of gravity. The workpiece is clamped and fixed by the third clamping member 402. The workpiece is driven to rotate around the third axis by the third rotating member 401, which facilitates machining.
[0064] This application provides a workpiece clamping and flipping device. The first clamping assembly 200, the second clamping assembly 300, and the third clamping assembly 400 respectively clamp the workpiece located in the mounting frame 100 and change its flipping direction, achieving 360° flipping of the workpiece and improving machining efficiency. The cooperation of the first sliding seat 203, the first rotating member 201, and the first clamping member 202 avoids affecting the workpiece loading into the mounting frame 100 and quickly clamps the workpiece loaded into the mounting frame 100 to flip it around the first axis. The cooperation of the second rotating member, the second clamping member, the adjusting member, and the bearing member quickly clamps the workpiece loaded into the mounting frame 100 to flip it around the second axis, and facilitates the adjustment of the angle of heavy workpieces for clamping with the third clamping member 402.
[0065] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0066] The above embodiments are only used to illustrate the technical solutions of this application and not to limit them; although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this application or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of this application, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in this application.
