The third threaded rod 19 can be driven to rotate to mobilize the movable frame 7 to move, thereby facilitating the contact and grinding of the grinding disc 15 with the side surface of the protective door. The inner wall of the movable frame 7 is rotatably connected to the first threaded cylinder 10, and the outer wall of the first threaded cylinder 10 is threadedly connected to the support rod 11, and the outer wall of the support rod 11 is provided with an edging assembly, which facilitates the grinding of the fire door.

[0023] The edging assembly includes a connecting frame 13, the outer wall of the connecting frame 13 is rotatably connected to the grinding disc 15, the outer wall of the connecting frame 13 facing away from the grinding disc 15 is fixedly connected to the second servo motor 14, and the output shaft of the second servo motor 14 is fixedly connected to the grinding disc 15. The second servo motor 14 is started by power supply, so that the output shaft of the second servo motor 14 drives the grinding disc 15 to rotate at high speed.

[0024] The inner wall of the support rod 11 is rotatably connected to the second threaded rod 12, and the connecting frame 13 is threadedly connected to the second threaded rod 12. The outer wall of the support rod 11 is provided with a driving motor 20 for driving the second threaded rod 12. The driving motor 20 is started by an external power switch to drive the second threaded rod 12 to rotate, thereby driving the connecting frame 13 to move left and right through the second threaded rod 12, thereby facilitating the grinding disc 15 to grind the fire door.

[0025] A stepper motor 16 is fixedly connected to the inner wall of the support platform 5, and the output shaft of the stepper motor 16 is fixedly connected to the placement rack 6.

[0028] The implementation principle of a steel insulated fire door edge grinding device in the embodiment of the present application is as follows: first, a worker places the protective door at the center position of the placement rack 6, and then starts multiple electric cylinders 3 to enable an external encoder to perform feedback control. The encoder can monitor the positions of the multiple electric cylinders 3 in real time and feed back the position information to the control system. By comparing the position information of different electric cylinders, the control system adjusts the rotation speed of the electric cylinder in real time, so that the multiple electric cylinders 3 synchronously drive the multiple fixing plates 4 to fix the four points of the fire door, thereby achieving the stability of the fire door. The first servo motor 8 is started by power supply, so that the output shaft of the first servo motor 8 drives the first threaded cylinder 10 to rotate, ensuring that the first threaded cylinder 10 drives the support rod 11 to move up and down, so as to adjust the position of the grinding disc 15 so that the grinding disc 15 is aligned with the side surface of the fire door, and then the second servo motor 14 is set to start the power supply to drive the grinding disc 15 to rotate at high speed, so that it is convenient to grind the edge of the fire door, and the external power switch The third servo motor 17 is started, so that the output shaft of the third servo motor 17 drives the third threaded rod 19 to rotate, so that the third threaded rod 19 synchronously drives the movable frame 7 to move, so that the movable frame 7 moves toward the side surface of the fire door, so that the grinding disc 15 contacts it, and then the grinding disc 15 performs edge grinding on the fire door. By driving the second threaded rod 12 to rotate, the second threaded rod 12 drives the connecting frame 13 to move back and forth, which facilitates the grinding disc 15 to grind the edge. When the side surface of the fire door is finished, the movable frame 7 can be moved in the opposite direction of the fire door, thereby starting multiple electric cylinders 3, so that the multiple electric cylinders 3 drive the multiple fixed plates 4 to loosen the fixation of the fire door, and then starting the stepper motor 16, so that the stepper motor 16 drives the fire door on the placement frame 6 to rotate through the output shaft. The stepper motor 16 receives a pulse signal to control its rotation angle, and quickly changes the side surface of the fire door. Then, the above operation is repeated to fix and grind it.
