By providing the third hydraulic moving machine 916, the height of the third moving plate 917 can be changed under control.
[0026] Working principle: When in use, the operator places the metal frame to be polished on the upper surfaces of the placing plate 62 and the sliding plate 614. Then, the bent rod 68 is rotated, causing the bent rod 68 to rotate and the positioning frame 69 to wrap around the end of the metal frame. Then, the first threaded rod 611 is rotated, causing it to rotate and move downward in the inner cavity of the first threaded ring 610. Finally, the clamping plate 612 squeezes and clamps the upper surface of the metal frame, completing the positioning and installation of the metal frame. Then, the first hydraulic moving machine 95, the second hydraulic moving machine 910, and the third hydraulic moving machine 916 are respectively controlled, causing the first moving plate 94, the second moving plate 912, and the third moving plate 917 to rotate until the first grinding cylinder 98, the second grinding cylinder 914, and the third grinding cylinder 919 are in close contact with the outer surface of the metal frame. Then, the second motor 97, the third motor 913, and the fourth motor 918 are controlled to start working, causing the first grinding cylinder 98, the second grinding cylinder 914, and the third grinding cylinder 919 to rotate. Then, the operator connects the first motor 64 to the power supply and turns on the switch, causing the rotating rod 65 to drive the gear 66 to rotate. During the rotation of the gear 66, it will engage with the rack 4, finally causing the placing plate 62 to move horizontally on the upper surface of the operating table 1. When the placing plate 62 moves horizontally, the roller 721 will contact the upper surface of the anti-slip piece 8, causing the roller 721 to rotate on the outer surface of the limiting rod 720 and the ribbon 723 to be wound. When the ribbon 723 is wound, the second connecting ring 713 will drive the sliding plate 614 to move. During the movement, the grinding block 616 grinds the corners of the metal frame. When the roller 721 no longer contacts the anti-slip piece 8, under the influence of the elastic potential energy of the first spring 711, the sliding plate 614 rebounds and returns to its original position. When the metal frame moves horizontally, the piston 77 will also move in the inner cavity of the track tube 72, squeezing the air and entering the inner cavity of the collection box 786. Finally, the slag and dust generated by grinding enter the inner cavity of the track tube 72 through the ash inlet frame 71 and are finally blocked and collected by the collection box 786.
