[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-4 This utility model discloses a polishing device for motorcycle production, which includes a polishing barrel 1. A clamping platform 9 is movably connected inside the polishing barrel 1. One end of the clamping platform 9 is fixedly installed on one end of a nut seat 8. A guide ring 16 is fixedly connected to the lower end of the polishing barrel 1. A sleeve 18 is slidably connected inside the guide ring 16. A symmetrical second spring 17 is fixedly installed at the lower end of the polishing barrel 1. The lower end of the symmetrical second spring 17 is fixedly connected to the upper end of a vibrating frame 26. The lower end of the polishing barrel 1 is fixedly connected to a base 3 through multiple first spring seats 2. When vibrating to drive polishing, it can not only help buffer the vibration impact of the polishing barrel 1 to protect the equipment and stabilize the wheel hub, but also maintain the regularity of the vibration of the polishing barrel 1, ensuring that the polishing sand inside the barrel flows stably in all directions with the barrel body and fully covers the surface of the wheel hub.

[0026] Specifically, a plurality of first spring seats 2 are fixedly installed at the lower end of the polishing barrel 1, and the other end of the plurality of first spring seats 2 is fixedly installed at the upper end of the base 3. This provides stable installation support for the polishing barrel 1 and can also help buffer the vibration impact force by means of the elastic characteristics of the spring seats when the polishing barrel 1 vibrates.

[0027] Specifically, a third spring 24 is fixedly connected inside the sleeve 18, and a first bearing 19 is rotatably connected to the outside of the sleeve 18 away from the guide ring 16. A connecting rod 20 is rotatably connected to the first bearing 19, and a sliding connection is made to the connecting rod 20 inside the sleeve 18. The third spring 24 can release elastic potential energy to pull the sleeve 18 back to its original position after the sleeve 18 completes its impact on the polishing barrel 1. This provides key support for the continuous reciprocating impact of the sleeve 18 on the polishing barrel 1 and ensures the stable vibration of the polishing barrel 1, thereby helping the polishing sand inside the barrel to flow evenly to achieve efficient polishing of the wheel hub.

[0028] Specifically, the end of the connecting rod 20 away from the first bearing 19 is rotatably connected to the second bearing 21. An eccentric block 22 is rotatably connected to the second bearing 21. The other end of the eccentric block 22 is fixedly connected to the drive shaft 23. The other end of the drive shaft 23 is rotatably connected to the first motor 5. Utilizing the centrifugal force characteristics of the eccentric block 22, the connecting rod 20 is driven to reciprocate through the second bearing 21. Ultimately, the rotational power of the first motor 5 is efficiently converted into the reciprocating power of the connecting rod 20, providing the core driving force for the sleeve 18 to reciprocate and impact the polishing barrel 1 and maintain the continuous vibration of the polishing barrel 1.

[0029] Specifically, a plurality of symmetrical sliding blocks 10 are fixedly installed on the upper end of the clamping platform 9. A slider 11 is slidably connected within the plurality of symmetrical sliding blocks 10. The sliding blocks 10 and the slider 11 are adapted to each other, allowing the slider 11 to slide stably along the trajectory of the sliding blocks 10, so as to allow the rotating disk 13 to drive the clamping block 12 to adjust the spacing.

[0030] Specifically, a rotating disk 13 is slidably connected to the upper end of the sliding block 10. Multiple arc-shaped through holes 14 are opened on the rotating disk 13. When the rotating disk 13 is driven by the third motor 15 to rotate, the arc-shaped through holes 14 guide the slider 11 to slide synchronously along the sliding block 10 through the trajectory, thereby coordinating the spacing of the multiple clamping blocks 12.

[0031] Specifically, multiple clamping blocks 12 are slidably connected within multiple arc-shaped through holes 14. The lower ends of the clamping blocks 12 are fixedly connected to the corresponding sliders 11. The lower ends of the clamping blocks 12 are adapted to the arc-shaped through holes 14. The lower end of the rotating disk 13 is rotatably connected to a third motor 15. The third motor 15 is fixedly connected to the clamping platform 9. The clamping blocks 12 adapted to the arc-shaped through holes 14 will slide along the through holes under the guidance of the arc-shaped trajectory, while simultaneously driving the sliders 11 fixed at the lower end to move synchronously along the sliding block 10.

[0032] Specifically, the nut seat 8 is internally threaded with a lead screw 25, the upper end of the lead screw 25 is rotatably connected to a second motor 7, and the other end of the nut seat 8 is slidably connected to a guide rod 6. The second motor 7 and one end of the nut seat 8 are fixedly connected to the upper end of the connecting seat 4, and one end of the connecting seat 4 is fixedly connected to one end of the base 3. This provides a solid support for the second motor 7 to drive the lead screw 25 to rotate and drive the nut seat 8 to move stably in a straight line along the guide rod 6, thereby ensuring the accuracy of the subsequent clamping platform 9 and the adjustment of the wheel hub height.

[0033] Working principle:

[0034] During clamping and fixing: The third motor 15 starts, driving the rotating disk 13 to rotate; the arc-shaped through hole 14 on the rotating disk 13 drives the clamping block 12, causing the clamping block 12 to slide along the slider 11 of the sliding block 10, thereby flexibly adjusting the spacing of the clamping blocks 12, realizing the clamping and fixing of motorcycle wheel hubs with different diameters and spoke layouts, without the need to change special fixtures, and adapting to the production of multi-specification wheel hubs. During height adjustment: The second motor 7 operates, driving the lead screw 25 to rotate; the nut seat 8 moves linearly along the lead screw 25 under the guidance and constraint of the guide rod 6, thereby driving the clamping platform 9 and the fixed wheel hub to move up and down, accurately adjusting the height position of the wheel hub in the polishing barrel 1. During vibration drive: The first motor 5 drives the first motor through the transmission shaft 23 to rotate the first motor 7 to rotate the second motor 8 to rotate the second motor 9 to rotate the third motor 7 to rotate the second motor 8 to rotate the second motor 9 to rotate the third motor 8 to rotate the second motor 9 to rotate the second motor 8 to rotate the third motor 9 to rotate the second motor 8 to rotate the second ...8 to rotate the second motor 9 to rotate the second motor 8 to rotate the second motor 8 to rotate the second motor 8 to rotate the second motor 8 to rotate the second motor 8 to rotate the second motor 8 The eccentric block 22 rotates; the eccentric block 22 drives the connecting rod 20 to move via the second bearing 21, and the connecting rod 20 pushes the sleeve 18 to reciprocate against the polishing barrel 1 within the guide ring 16 via the first bearing 19. The third spring 24 assists in releasing elastic potential energy to pull the sleeve 18 back to its initial position; at the same time, the second spring 17 cooperates with the vibration frame 26 to make the polishing barrel 1 obtain continuous and stable vibration; in addition, the lower end of the polishing barrel 1 is connected to the base 3 via multiple first spring seats 2 to assist in buffering and maintaining the regularity of vibration. The polishing barrel 1 is filled with polishing sand. Under the action of vibration, the polishing sand flows in all directions with the barrel body and fully wraps the surface of the wheel hub; through the flexible friction between the polishing sand and the wheel hub, the wheel hub is polished evenly.
