[0034] A drive motor 17 is mounted on one side of the servo motor 14, and the drive motor 17 is connected to the drive wheel set 5 for transmission.

[0035] It should be noted that the drive motor 17 drives the drive wheel assembly 5, which in turn drives the driven sprocket 4 via the drive chain 9. The driven sprocket 4 synchronously drives the rotating disk 3 to rotate, which in turn drives the polishing needles inside the polishing box 1 to polish the workpiece surface. The drive screw 15 is driven by the servo motor 14, which, under the action of the surface thread, pushes the mounting bracket 6 to move under the guidance of the guide rod 13. The drive chain 9 passes through the through slot 7, and the tension wheel 10 is rotated and mounted at the bottom of the mounting bracket 6. The mounting bracket 6 can push the chain near the drive wheel assembly 5 to move, allowing the drive chain 9 to move on drive discs of different diameters. By driving the driven sprocket 4 with drive discs of different sizes, the drive motor 17 can mechanically adjust the speed of the rotating disk 3 at the same speed, which can reduce power consumption and make it more energy-efficient.

[0036] In this embodiment, as Figure 1 and Figure 2 As shown, the top of the mounting bracket 6 has a through groove 7, the drive chain 9 passes through the inner cavity of the through groove 7, and guide rollers 8 are rotatably provided on both sides of the inner wall of the through groove 7, the guide rollers 8 are attached to the two side surfaces of the drive chain 9.

[0037] It should be noted that the guide roller 8 guides the drive chain 9 to prevent the drive chain 9 from rubbing against the inner wall of the through groove 7.

[0038] In this embodiment, as Figure 1 and Figure 2 As shown, the bottom surface of the mounting bracket 6 is provided with an adjustment groove 11, the inner cavity of the adjustment groove 11 is provided with a support spring 12, the tension wheel 10 is rotatably mounted on the slide block, and the slide block is slidably connected to the adjustment groove 11, and the end of the support spring 12 is connected to the slide block.

[0044] The working principle and usage process of this utility model are as follows: The drive motor 17 drives the drive wheel assembly 5, which in turn drives the driven sprocket 4 via the drive chain 9. The driven sprocket 4 synchronously drives the rotating disk 3 to rotate, which in turn drives the polishing needles inside the polishing box 1 to polish the workpiece surface. The servo motor 14 drives the drive screw 15, which, under the action of the surface thread, pushes the mounting bracket 6 to move under the guidance of the guide rod 13. The drive chain 9 passes through the through slot 7, and at the same time, the tension wheel 10 is rotated and installed at the bottom of the mounting bracket 6. The mounting bracket 6 can push the chain near the drive wheel assembly 5 to move, allowing the drive chain 9 to move without... The driven sprocket 4 moves on a drive wheel of the same diameter and is driven by drive wheels of different sizes. The drive motor 17 mechanically adjusts the rotation speed of the rotating disk 3 at the same speed, which can reduce power consumption and make it more energy-efficient. The support spring 12 supports the slide on the tension wheel 10. The slide moves in the adjustment groove 11 and can be tensioned when the drive chain 9 is adjusted. When the mounting bracket 6 adjusts the drive chain 9, the tension wheel 10 can move synchronously, which can keep the drive chain 9 parallel to the drive wheel. The guide roller 8 guides the drive chain 9. The anti-drop cover 16 can limit the drive chain 9 on both sides of the driven sprocket 4 to prevent the chain from dropping.
