[0024] Working principle:

[0025] First, the operator places the plate to be polished on the placement rack 16, and then the operator starts the second cylinder 15. The telescopic end of the second cylinder 15 drives the second guide rail 3 fixedly connected thereto to move on the first guide rail 2. Therefore, when the second guide rail 3 moves on the first guide rail 2, the rotating block 13 rotates and drives the two connecting rods 14 to synchronously move the two second guide rails 3, so that the two guide rails can be synchronously approached on the two first guide rails 2.

[0026] Then the operator starts the first cylinder 5, and the first cylinder 5 drives the first motor 26 and the polishing wheel 6 to approach the plate. When the polishing wheel 6 abuts against the upper surface of the plate, the operator starts the first motor 26, and the first motor 26 drives the polishing wheel 6 to polish the plate. When the operator needs to expand the polishing area of ​​the plate, the operator starts the second motor 17, and the second motor 17 drives the second screw 18, and the second screw 18 drives the second slider 20, so that the second slider 20 drives the first cylinder 5 and the polishing wheel 6 to move. When the operator needs to further expand the polishing area of ​​the plate, the operator starts the third motor 25, and the third motor 25 drives the third screw 22, and the third screw 22 drives the third slider 24 to move in the slide groove 21, thereby driving the movement of the support frame 4 through the movement of the third slider 24, thereby expanding the polishing area of ​​the plate by the polishing wheel 6.

[0027] When the polishing wheel 6 is polishing the surface of the plate, the operator can start the fan 30, and the fan 30 sucks the dust in the shielding cover 27 into the filter box 28 through the hose 29. The filter box 28 can filter the sucked dust to reduce the damage of the dust to the operator's body during polishing.
