[0022] The polishing assembly includes four electric push rods 10, which are respectively installed at the four corners of the bottom end of the base 8, and the output ends of the electric push rods 10 extend above the base 8 and are provided with a top plate 11, one side of the top end of the top plate 11 is provided with an electric guide rail 3, and the inside of the electric guide rail 3 is slidably provided with an electric sliding seat 2, the top end of the electric sliding seat 2 is provided with a drive motor 1, and the output end of the drive motor 1 extends below the top plate 11 and is provided with a polishing roller 4 through bolts;

[0023] Specifically, as shown in the figure, Figure 1 , the extension and retraction of the electric push rod 10 can drive the top plate 11 to move up and down, thereby changing the vertical position of the polishing roller 4, and at the same time, the electric sliding seat 2 can slide inside the electric guide rail 3, thereby changing the horizontal position of the polishing roller 4. The cooperation of the two can make the polishing roller 4 be in the appropriate position for polishing operation. The drive motor 1 is used to drive the polishing roller 4 to rotate for polishing, and the drive motor 1 and the polishing roller 4 can continue to be disassembled, which is convenient for replacing the polishing roller 4.

[0027] The driving assembly comprises a rotating shaft 15, which is installed between the upper and lower ends in the installation box 6 through the shaft, and the top of the outer wall of the rotating shaft 15 is fixed with a driving bevel gear 16.

The second servo motor 9 can drive the worm 18 to rotate, so that the rotating shaft 15 rotates through the transmission of the worm 18 and the worm gear 19. In this way, the driving bevel gear 16 can rotate with the rotating shaft 15, so that the three lead screws 12 rotate at the same speed through the cooperation of the driving bevel gear 16 and the driven bevel gear 13. Therefore, the three sliding blocks 17 can move closer or apart at the same speed, so as to ensure that the center of the annular workpiece and the center of rotation of the installation box 6 are on the same vertical line.
