A first motor 125 is fixedly connected to the front of the fixing frame 121 located in the front. The output end of the back of the first motor 125 is fixedly connected to the front of the rotating shaft 221. By setting the grinding box 11, specifically, when the sheet metal part 112 is driven to the left and contacts the grinding roller 122, the surface of the sheet metal part 112 will be ground. At the same time, the lifting seat 12 is pushed downward by the elastic force of the spring 124. Then the lifting seat 12 drives the grinding roller 122 to move downward together through the fixing frame 121. At the same time, the grinding roller 122 is closely attached to the surface of the sheet metal part 112, making the grinding more uniform and improving the grinding effect, avoiding the situation of incomplete grinding, and the grinding roller 122 can quickly grind the sheet metal part 112, improving the work efficiency.

[0028] A rotating rod 13 is arranged on the left side of the lifting seat 12. A plurality of cleaning brushes 131 are fixedly connected to the outer surface of the rotating rod 13. The front and back of the rotating rod 13 are both rotatably connected to the grinding box 11. The front of the rotating rod 13 is fixedly connected to the output end of the back of the third motor 3.

The front of the driving wheel 153 on the right is fixedly connected to the output end of the back of the second motor 2. Starting the second motor 2 drives the driving wheel 153 on the right to rotate counterclockwise. Then the driving wheel 153 drives the conveyor belt 152 to drive to the left, and the sheet metal part 112 is driven to the left.

[0031] There is a square groove on the front of the grinding box 11. The first motor 125 is arranged inside the square groove. There is a leakage groove 113 on the top of the workbench 1. A collection box 4 is inserted into the workbench 1.

The left side of the moving block 142 in the front is in contact with the right side of the grinding box 11. The mutually approaching sides of the two limiting blocks 14 are both in contact with the surface of the sheet metal part 112. The top of the conveyor belt 152 is in contact with the bottom of the sheet metal part 112.

[0033] A specific application of this embodiment is:

[0034] Put the sheet metal part 112 into the opening 111 on the right side of the grinding box 11, so that the sheet metal part 112 contacts the conveyor belt 152 inside the grinding box 11. Then, turn the handle 145 clockwise to drive the threaded rod 143 to rotate. The moving block 142 moves backward on the threaded rod 143. The moving block 142 drives the front limiting block 14 to move backward through the connecting frame 141. Since the left side of the moving block 142 contacts the right side of the grinding box 11, the moving block 142 can move in a straight line. Then, the front and rear limiting blocks 14 will push and position the sheet metal part 112 and limit the sheet metal part 112, so that the sheet metal part 112 will not shift when moving, thus making the grinding effect better. After the sheet metal part 112 is limited, start the second motor 2 to drive the right transmission wheel 153 to rotate counterclockwise. Then, the transmission wheel 153 drives the conveyor belt 152 to transmit to the left. Then, the sheet metal part 112 is transmitted to the left. At the same time, the conveyor belt 152 on the back will be started simultaneously. Then, start the first motor 125 to drive the rotating shaft 221 to rotate. Then, the rotating shaft 221 drives the grinding roller 122 to rotate. When the sheet metal part 112 contacts the grinding roller 122, the surface of the sheet metal part 112 will be ground. At the same time, the lifting seat 12 is pushed downward by the elastic force of the spring 124. Then, the lifting seat 12 drives the grinding roller 122 to move downward together through the fixing frame 121, so that the grinding roller 122 is closely attached to the surface of the sheet metal part 112, making the grinding more uniform and improving the grinding effect, avoiding the situation of incomplete grinding. And the grinding roller 122 can quickly grind the sheet metal part 112, improving the work efficiency. Then, after the ground sheet metal part 112 moves to the position of the cleaning brush 131, start the third motor 3 to drive the rotating rod 13 to rotate. Then, the cleaning brush 131 rotates together. After the cleaning brush 131 contacts the sheet metal part 112, the debris remaining on the surface of the sheet metal part 112 will be cleaned, so that the surface of the sheet metal part 112 is cleaner when it comes out of the left side of the grinding box 11, and it does not need to be cleaned by the staff again. Finally, the sheet metal part 112 is removed from the opening 111 on the left side of the grinding box 11 to complete the grinding. The debris generated during the grinding process is discharged through the chip discharge port 151 and enters the collection box 4 through the leakage groove 113 for collection.
