During the clamping of the multilayer board, the rotating rod 14 rotates to move the clamping plate 16, and the two pairs of clamping plates 16 move to clamp and fix the upper and lower surfaces of the two ends of the multilayer board. Since the surface of the clamping plate 16 is fixedly connected to the rubber pad 25, during the clamping of the multilayer board, indentations on the surface of the multilayer board can be prevented, thereby ensuring the beauty of the multilayer board.

[0033] The use steps of the utility model are as follows: when the multi-layer board processing flip-over grinding device is in use, the two clamping devices 8 move toward each other to clamp the multi-layer board. During the clamping process of the multi-layer board, the rotating rod 14 rotates to move the clamping plate 16. The two pairs of clamping plates 16 move to clamp and fix the upper and lower surfaces of the two ends of the multi-layer board. Since the surface of the clamping plate 16 is fixedly connected with the rubber pad 25, the surface of the multi-layer board can be prevented from being indented during the clamping process of the multi-layer board, thereby ensuring the beauty of the multi-layer board.
