[0033] Working principle: When the conveyor belt 2 starts, the parts to be processed on the top of the conveyor belt 2 are conveyed to the front of the working station. Then the conveyor belt 2 stops working. The electric telescopic rod 22 drives the clamping assembly 23 to move. While the fourth motor 234 drives the rotating rod 233 to rotate, it also drives the connecting block 235 to rotate. While the connecting block 235 drives the clamp 236 to move, it also drives the anti-slip pad 237 to move to clamp and fix the parts to be processed. After the fixation is completed, the electric telescopic rod 22 drives the clamping assembly 23 to move. The parts to be processed are placed on the top of the placement plate 18. The first motor 9 drives the fixed rod 10 to rotate while driving the grinding head 11 to rotate. The electric sliding table 19 drives the third motor 20 while driving the fixed plate 21 to lift and lower. The fixed plate 21 drives the electric telescopic rod 22 while driving the clamping assembly 23 and the parts to be processed to lift and lower, moving up and down. The second motor 14 drives the lead screw 13 to rotate while driving the slider 15 to move. The slider 15 drives the placement plate 18 to move while driving the parts to be processed to move, moving horizontally. The grinding head 11 processes the parts to be processed. The third motor 20 drives the fixed plate 21 to rotate while driving the electric telescopic rod 22 and the clamping assembly 23 to rotate, turning the parts to be processed over so that the reverse side can be processed. Place the parts on the top of the anti-slip soft pad 27. The fifth motor 25 drives the connecting plate 26 to rotate while driving the anti-slip soft pad 27 to rotate. The anti-slip soft pad 27 drives the parts to rotate to adjust the orientation. After the adjustment is completed, the clamping assembly 23 clamps and fixes the parts again. The grinding head 11 processes the outer wall of the parts. Move the mounting block 6 to drive the clamping block 7 and the mounting plate 8 to move. The clamping block 7 is pulled out of the clamping slot 5. The mounting block 6 and the mounting plate 8 are separated from the conveyor belt 2, which is detachable and convenient for overhauling, maintaining and replacing the first motor 9 and the grinding head 11.

[0034] While the third motor 20 drives the fixed plate 21 to rotate, it also drives the electric telescopic rod 22 and the clamping assembly 23 to rotate, turning the part to be processed over so that the reverse side can be processed. Place the part on the top of the anti-slip soft pad 27. While the fifth motor 25 drives the anti-slip soft pad 27 to rotate, it also drives the part to rotate, adjusting the orientation. The clamping assembly 23 clamps and fixes the part again, and the grinding head 11 processes the outer wall of the part, achieving a turning effect, enabling comprehensive processing of the part, reducing limitations and improving practicability at the same time.

[0035] The moving mounting block 6 drives the clamping block 7 and the mounting plate 8 to move. The clamping block 7 is withdrawn from the clamping groove 5, and the mounting block 6 and the mounting plate 8 are separated from the conveyor belt 2, which is detachable and facilitates the overhaul, maintenance and replacement of the first motor 9 and the grinding head 11, extending the service life of the equipment.
