[0031] Working principle: When in use, first place the stone on the top surface of the processing seat 2, then activate the electric push rod 5, the electric push rod 5 drives the connecting block 6 to move on the surface of the guide rod 4, and then activate the cylinder 7, the cylinder 7 drives the support plate 8 to move, and finally activate the drive motor 9, the drive motor 9 drives the grinding head 10 to move. At this time, under the action of the electric push rod 5, the cylinder 7 and the drive motor 9, the grinding head 10 can grind the surface of the stone. Before grinding begins, turn on the rotating motor 17, and the rotating motor 17 immediately drives the driving gear 18 to rotate. The wheel 18 is meshed with the driven gear 16, so the driving gear 18 drives the driven gear 16 to rotate, and the driven gear 16 then drives the bidirectional threaded rod 15 to rotate. Since the slider 13 is meshed with the bidirectional threaded rod 15, the bidirectional threaded rod 15 drives the two sets of sliders 13 to move when moving, and the two sets of sliders 13 then drive the protective cover 14 to move toward each other on the surface of the slide bar 12 until the two sets of sliders 13 drive the protective cover 14 to stick to each other, and the protective cover 14 then covers the processing seat 2, turns off the rotating motor 17, and then starts grinding, and the protective cover 14 can The debris or powder dust splashed during the grinding process is shielded. When the processing is completed, the rotating motor 17 is reactivated, and the rotating motor 17 drives the two-way threaded rod 15 to rotate in the opposite direction. The two-way threaded rod 15 drives the two sets of sliders 13 to move relative to each other. The two sets of sliders 13 simultaneously drive the protective cover 14 to move until the two sets of sliders 13 slide to the outermost end of the slide rod 12. At this time, the protective cover 14 can expose the processing seat 2, and then turn off the rotating motor 17. The protective cover 14 can be fixed in this position, and then the polished stone can be removed from the top surface of the processing seat 2. After cleaning the processing table 1 When cleaning the surface, manually hold the pull groove 22 and pull the pull groove 22 outward. At this time, the pull groove 22 drives the hook 21 to rotate inside the rectangular groove 20, separating the magnet 23 on the inner wall of the rectangular groove 20 from the hook 21, and then continue to rotate the hook 21 until the bottom end of the hook 21 is against the inner wall of the rectangular groove 20. At this time, the cleaning brush and other tools can be removed from the hook 21. After the cleaning tool is removed, manually pull the hook 21 upward, and the hook 21 moves upward inside the rotating shaft until the top surface of the hook 21 is in contact with the magnet 23. At this time, the hook 21 can be stored in the rectangular groove 20.
