Then, the fourth motor 10 is turned to rotate the lead screw 9, which moves the clamping plate 7 to hold the plastic part. Next, the bracket 4 and the electric push rod mounting end 11 are moved so that the polishing wheel 19 can grind the clamped plastic part. Then, the third motor 24 is started to rotate the rotating shaft 18, which in turn rotates the polishing wheel 19 for grinding. After grinding the current position is completed, the polishing wheel 19 can be adjusted by starting the first motor 22 to rotate the first worm gear 20, which in turn rotates the meshing first worm wheel 15. This allows the polishing wheel 19 to be rotated vertically, enabling grinding of more areas of the plastic part. Similarly, the polishing wheel 19 can be adjusted by starting the second motor 23 to rotate the second worm gear 21, which in turn rotates the meshing second worm wheel 16. This allows the polishing wheel 19 to be rotated horizontally, enabling grinding of more areas of the plastic part. In this way, the plastic part can be ground in more directions, improving work efficiency.
