[0015] The working principle of the technical solution is as follows: the electromagnet is not energized, and the first fixed rod is located in the groove, so that the slide rod cannot slide in the slide groove, and the slide rod is fixed to the second grinding block. The metal sheet is placed on the support block, and the fourth driving member is started. The fourth driving member drives the fifth driving member and the slide rod to move toward the metal sheet until the second grinding blocks on both sides clamp the metal sheet. The vertical moving part and the front and rear moving part respectively adjust the vertical and front and rear positions of the first grinding block, so that the two sides of the first grinding block are respectively attached to the upper side and the rear side of the plate. The first driving member is started, and the first driving member drives the cylindrical cam to rotate.

After the flipping is completed, start the third driving member so that the support block supports the metal sheet. According to the above steps, reposition the first grinding block and grind the other two sides of the metal sheet. When the four surfaces of the front, back, top and bottom of the metal sheet are polished, turn off the first driving member, energize the electromagnet, so that a repulsive force is generated between the electromagnet and the iron block. The first fixed rod will be completely retracted into the connecting column under the action of the repulsive force. Under the action of the connecting column, the second fixed rod will move outward until it contacts the surface of the metal sheet, pressing the metal sheet. At the same time, the first grinding block will not be retracted and will continue to press on the surface of the metal sheet. Due to the retraction of the first fixed rod, the first fixed rod can slide in the slide groove. The second driving member is started, and the second driving member drives the gear to rotate, and the gear drives the rack and the second grinding block to move forward and backward. The second grinding block moves forward and backward relative to the metal plate, so that the left and right sides of the metal plate can be ground.
