A threaded hole matching the screw rod 405 is opened in the middle part of the movable plate 402. By setting the handle 406 and the screw rod 405, the distance from the grinding roller 408 to the door frame 7 can be controlled to improve the grinding quality.

[0025] In this embodiment, two U-shaped support frames 1 are fixedly connected to the same workbench 2 in the middle of the top, a strip hole 201 is opened in the middle of the workbench 2, and a fixing mechanism 6 is arranged in the middle of the workbench 2. The fixing mechanism 6 includes a bidirectional screw rod 601 rotatably connected between the two ends of the inner side of the strip hole 201, and symmetrical thread grooves are opened at both ends of the bidirectional screw rod 601. Clamping rods 602 are threadedly sleeved at both ends of the bidirectional screw rod 601.

[0029] Working principle: A grinding device for anti-theft doors. When in use, place the door frame 7 on the door frame support frame 603 to support the door frame 7, start the motor 607, and rotate the bidirectional screw 601 through the worm 605 and the worm wheel 604. The two clamping rods 602 are close to each other until the door frame 7 is fixed. The clamping rod 602 is narrower than the door frame 7. The worm 605 and the worm wheel 604 are set so that the door frame 7 will not loosen after being fixed. Start the drive motor 409 to make the grinding roller 408 start to rotate, and turn the handle 406 to make the grinding roller 408 close to the door frame 7. Until the door frame 7 is polished, there is no need to turn the handle 406 at this time. Slowly push the movable plate 402 to make the polishing roller 408 slide from the door frame 7 until one side of the door frame 7 is polished, and continue to push the polishing mechanism 4.
