Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a wheel hub clamping mechanism technical solution, including a lifting housing 1, a rectangular space inside the lifting housing 1, a partition plate 21 inside the rectangular space, the partition plate 21 dividing the rectangular space into a transmission cavity 22 and a lifting cavity 23, a lifting and rotating assembly between the partition plate 21, the transmission cavity 22 and the lifting cavity 23, one end of a receiving plate 3 is fixedly connected to the upper surface of the lifting and rotating assembly, one end of four support columns 4 is fixedly connected to the upper surface of the other end of the receiving plate 3, the other end of the support columns 4 is fixedly connected to a worktable 5, a clamping assembly is provided on the worktable 5, four clamping grooves 6 are provided on the worktable 5, and the clamping grooves 6 cooperate with the clamping assembly.

[0025] See Figure 2 and Figure 3The clamping assembly includes a motor fixing frame 8 fixedly connected to the lower surface of the workbench 5. Two telescopic motors 10 are fixedly connected within the motor fixing frame 8. The extension shaft of each telescopic motor 10 is connected to one end of a telescopic rod 11. The other end of the telescopic rod 11 is fixedly connected to one end of a force transmission plate 14. The other end of the force transmission plate 14 is fixedly connected to one end of a connecting plate 13. The other end of the connecting plate 13 passes through a clamping groove 6 and is fixedly connected to a clamping plate 12. The clamping assembly also includes a connecting shaft 20, one end of which is fixedly connected to the bottom of the connecting plate 13. The other end of the connecting shaft 20 is fixedly connected to one end of a connecting rod 15. The other end of rod 15 is fixedly connected to one end of connecting rod 2 16. The other end of connecting rod 2 16 is rotatably connected to one end of connecting shaft 17. The other end of connecting shaft 17 is rotatably connected to the upper surface of the force-bearing platform 18. One end of rotating shaft 19 is fixedly connected to the center of the upper surface of the force-bearing platform 18. The other end of rotating shaft 19 is fixedly connected to the bottom side of the workbench 5. Clamping plate 12, connecting plate 13, connecting shaft 2 20, connecting rod 15, connecting rod 2 16 and connecting shaft 17 form a clamping device. Four sets of clamping devices are evenly provided on the workbench 5. Telescopic motor 10 is welded to motor fixing frame 8.

[0026] See Figure 4 and Figure 5 The lifting and rotating assembly includes a transmission motor 24 fixedly connected inside the transmission cavity 22. The output end of the transmission motor 24 is connected to one end of the transmission shaft 25. One end of the transmission shaft 25 is slidably connected inside the lifting rod 2. The lifting rod 2 passes through the transmission cavity 22, the lifting cavity 23 and the partition plate 21 to the lifting housing 1 and the receiving plate 3 for fixed connection. The lifting and rotating assembly also includes a plurality of gear teeth 9 fixedly connected to the outer surface of the lifting rod 2. The gear teeth 9 are rotatably connected inside the lifting cavity 23. The inner sidewall of the lifting cavity 23 is fixedly connected to a lifting motor 26. The output end of the lifting motor 26 is fixedly connected to one end of the lifting shaft 28. The other end of the lifting shaft 28 is fixedly connected to a lifting gear 27. The lifting gear 27 meshes with the gear teeth 9. The telescopic motor 10 is welded to the motor fixing frame 8.

[0027] In use, when the wheel hub is placed on the workbench 5, the telescopic motor 10 is activated, causing the telescopic rod 11 to pull the force transmission plate 14 inward. This force transmission plate 14 then drives the connecting plate 13 and clamping plate 12 to move inward simultaneously. As the connecting plate 13 moves, it drives the connecting shaft 20 to press the connecting rod 15 and connecting rod 16 inward, causing them to rotate. This, in turn, causes the connecting rod 16 to press the force-bearing platform 18 around the rotating shaft 19 via the connecting shaft 17, thus causing the force-bearing platform 18 to rotate. The movement of the force-bearing platform 18 also compresses the belt... The remaining connecting shaft 17 on the moving surface rotates, thereby driving the remaining connecting rods 15 and 16 to rotate inward around the connecting shaft 17. When the connecting rod 15 moves, it drives the remaining connecting plate 13 and clamping plate 12 to move through the connecting shaft 20. Under the limiting guidance of the clamping groove 6, the four clamping plates 12 will not deviate when they move, so that the four clamping plates 12 clamp the hub, making the hub convenient for the next stage of operation.

[0028] When it is necessary to adjust the height and rotation angle of the worktable 5, the drive motor 24 is started to drive the drive shaft 25. The drive shaft 25 is stopped by the locking plates 7 on both sides and the locking groove 29 in the lifting rod 22. The drive shaft 25 rotates, causing the lifting rod 2 to rotate in the same way. When the lifting rod 2 rotates, it drives the worktable 5 to rotate through the support plate 3 and the support column 4. The lifting motor 26 is started to drive the lifting shaft 28 to rotate the lifting gear 27. The lifting gear 27 meshes and drives the lifting rod 2 to move upward through the gear teeth 9. Then the lifting rod 2 drives the worktable 5 to rise or fall through the support plate 3 and the support column 4.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
