Similarly, the threaded rod 10 rotates in the opposite direction to drive the two clamping plates 13 to move away from each other, so that it is easy to remove the workpiece after grinding. After the workpiece is fixed, the drive motor 3 and the electric push rod 6 are started at the same time, and the grinding block 8 rotates synchronously during the downward movement. When the grinding block 8 is attached to the surface of the workpiece, the workpiece can be ground. When the grinding of one side of the workpiece is completed, the grinding block 8 is operated to move up and the placement table 19 is moved down, and the drive motor 3 is started to rotate the rotating plate 4 is rotated 180° and is perpendicular to the vertical plate 2 again, and the other side of the workpiece can be polished again by the polishing block 8, so that the workpiece can be flipped and polished while being clamped, without the need for secondary clamping, reducing the operation steps, saving time and effort, and improving the polishing efficiency. When in use, the drive motor 1 3, the drive motor 2 7, the electric push rod 6 and the forward and reverse motor 9 are all controlled by the connected power supply and the control switch provided on the bottom plate 1. The circuits and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and there is no need to elaborate.

[0021] Furthermore, the clamping assembly includes a forward and reverse motor 9, a threaded rod 10, a movable block 11, a connecting plate 12 and a clamping plate 13. A groove 14 is provided on the side of the rotating plate 4 away from the vertical plate 2. The forward and reverse motor 9 is arranged in the groove 14. The output end of the forward and reverse motor 9 is fixedly connected to one end of the threaded rod 10, and the other end of the threaded rod 10 is rotatably connected to the inner wall of the groove 14. The threaded rod 10 is threadedly connected to two movable blocks 11 with opposite thread rotation directions.

[0022] Furthermore, the surface of the movable block 11 is fitted on the inner wall of the groove 14 to maintain the stability of the movement of the clamping plate 13 and increase the firmness of the clamping plate 13 to clamp the workpiece.

[0023] Furthermore, anti-slip pads are fixedly connected to one side corresponding to the two clamping plates 13, which improves the connection stability between the clamping plates 13 and the workpiece, prevents the workpiece from sliding during the grinding process, and can protect the surface of the workpiece, avoiding damage to the surface of the workpiece by the clamping plates 13.

[0024] Furthermore, the supporting assembly includes a column 15, a return spring 16, a slider 17, a moving rod 18 and a placement table 19. The columns 15 are fixedly connected on both sides of the bottom plate 1. A T-shaped slide groove 20 is provided in the column 15. The slider 17 is slidably connected in the T-shaped slide groove 20. One end of the return spring 16 is fixedly connected to the bottom of the slider 17 at the bottom plate 1. The other end of the return spring 16 is fixedly connected to the bottom of the slider 17. The moving rod 18 is fixedly connected to the slider 17. The ends of the two moving rods 18 away from the slider 17 are fixedly connected to the same placement table 19. Before starting the operation, the bottom of the workpiece is attached to the top of the placement table 19. The placement table 19 provides support force for the workpiece, which is conducive to clamping The holding plate 13 clamps and fixes the workpiece. When the workpiece needs to be turned over, the handle 26 is pushed to drive the placement table 19, the moving rod 18 and the slider 17 to move downward. The slider 17 slides in the T-shaped slide groove 20 and drives the reset spring 16 to be compressed. The placement table 19 is away from the clamping plate 13, which is convenient for rotating the workpiece. The pressing force on the handle 26 is cancelled, and the reset spring 16 automatically extends to drive the slider 17 and the moving rod 18 to move upward, so that the placement table 19 is again attached to the bottom of the workpiece. The workpiece will vibrate during the grinding process. The placement table 19 is subjected to force vibration and drives the reset spring 16 to vibrate up and down, which can shake the grinding debris into the receiving groove 21 for collection, thereby increasing the practicality of the device.

[0025] Furthermore, a receiving groove 21 is provided on the placement table 19, and a cover plate 22 is threadedly connected to the top of the placement table 19. A plurality of filter holes 23 are provided on the cover plate 22. Debris generated by grinding can enter the receiving groove 21 through the filter holes 23. Opening the cover plate 22 facilitates the processing of the debris in the receiving groove 21.

[0026] Furthermore, a fixing rod 24 is fixedly connected to the bottom of the cover plate 22, and a collecting plate 25 is fixedly connected to the bottom of the fixing rod 24.

[0028] Working principle: When in use, place the workpiece on the placement table 19 and between the two clamping plates 13, start the forward and reverse motor 9 to drive the threaded rod 10 to rotate forward, the rotation of the threaded rod 10 drives the two movable blocks 11 to move in the groove 14, and then drives the clamping plates 13 on the two connecting plates 12 to approach each other, and the two clamping plates 13 approaching each other can clamp and fix the workpiece. Similarly, the reverse rotation of the threaded rod 10 drives the two clamping plates 13 away from each other, making it easy to remove the workpiece after grinding. After the workpiece is fixed, start the drive motors 13 and 2 at the same time. The electric push rod 6 and the grinding block 8 rotate synchronously during the downward movement. The grinding block 8 can grind the workpiece when it is in contact with the surface of the workpiece. After grinding one side of the workpiece, the grinding block 8 is operated to move up and the placement table 19 is moved down. The drive motor 3 is started to make the rotating plate 4 rotate 180° and be perpendicular to the vertical plate 2 again. The other side of the workpiece can be grinded again by the grinding block 8, so that the workpiece can be flipped and polished while being clamped. No secondary clamping is required, which reduces the operating steps, saves time and effort, and improves the grinding efficiency.
