[0033] The reset unit is used to always provide an upward thrust to the transmission unit;

[0034] The transmission unit includes a guide rod 501, a pressing block 502, a rack 503, a gear 504, a movable plate 505, and a limit block 506;

[0035] The guide rod 501 is axially slidably installed on the top of the workbench 1, and the guide rod 501 is used to provide guidance for the movement of the metal plate;

[0036] The pressing block 502 is vertically slidably installed inside the workbench 1 and extends to the outside of the workbench 1. The pressing block 502 is used to synchronously drive the rack 503 to move up and down;

[0037] The rack 503 is fixed to the bottom end of the pressing block 502, and the rack 503 is used to transmit power for the rotation of the gear 504;

[0038] The gear 504 is rotatably mounted inside the workbench 1, and the rotating gear 504 is used to provide thrust for the upward and downward movement of the movable plate 505;

[0039] The movable plate 505 is vertically slidably installed inside the workbench 1, and the movable plate 505 is used to synchronously drive the limit block 506 to move vertically;

[0042] The positioning rod 507 is fixed inside the workbench 1 and passes through the movable plate 505. The positioning rod 507 is used to provide guidance for the vertical movement of the movable plate 505;

[0043] The two ends of the spring 508 are respectively clamped to the inside of the workbench 1 and the top of the movable plate 505, and the spring 508 is used to always provide a downward thrust for the movable plate 505;

[0044] The polishing unit 4 includes a driving motor and a polishing wheel. The driving motor is fixed to the top of the lifting platform 3, and the polishing wheel is connected to the output end of the driving motor through a rotating shaft and a coupling.

[0045] In this embodiment: when using this device, a metal sheet to be polished is placed on the upper surface of the workbench 1 so that one end of the metal sheet is located below the polishing wheel and does not pass over the polishing wheel. The cylinder 2 is used to drive the lifting platform 3 to drive the polishing unit 4 to approach the metal sheet so that the polishing wheel on the polishing unit 4 contacts the metal sheet. The driving motor is started to drive the polishing wheel to rotate, thereby completing the polishing of the metal sheet. During this process, the contact between the metal sheet and the upper surface of the workbench 1 will give a downward squeezing force to the pressing block 502 on the workbench 1, so that the pressing block 502 enters the interior of the workbench 1. The downward movement of the pressing block 502 will synchronously drive the rack 503 to move downward. The downward moving rack 503 will give a rotational thrust to the gear 504, and the rotating gear 504 will push the movable plate 505 moves upward, so that the movable plate 505 moves along the outer wall of the positioning rod 507 and applies squeezing force to the spring 508.

At this time, the metal sheet will no longer contact the outer wall of the pressing block 502. At this time, the position of the guide rod 501 can be adjusted to facilitate polishing of the position of the metal sheet that is not in contact with the polishing wheel, reducing the situation where the metal sheet moves and deviates during the polishing process and needs secondary polishing, thereby further improving work efficiency.

[0046] Please refer to Figure 1-Figure 3 There are multiple limit blocks 506, which are evenly distributed on the outer wall of the movable plate 505.

The interior of the workbench 1 is formed with a slide groove for the vertical movement of the pressing block 502 and the rack 503.

[0047] In this embodiment: through this structure, when the pressing block 502 is not subjected to external squeezing force, the movable plate 505 affected by the elastic force of the spring 508 will move downward, thereby driving the pressing block 502 to move upward through the rack 503, so that the top part of the pressing block 502 is always exposed on the upper surface of the workbench 1, which is convenient for contact with the metal plate.
