In specific implementation, the electromagnetic clutch is a device that controls the start, stop and brake of the motor in the mechanical transmission system. When installing the electromagnetic clutch brake device, the positioning block 9 on one side of the connecting block 8 is connected to the positioning hole on one side of the connecting plate 10. When the inclined surfaces of the clamping blocks 15 on both sides of the positioning block 9 contact the connecting plate 10, the clamping blocks 15 will move and squeeze the connecting rod 14 on one side.

Please refer to Figures 1, 2 and 4. The outer side of the electrode body 3 is provided with a sliding groove that matches the slider inside the rotating ring 16, and the sliding groove is slidably connected to the rotating ring 16.

The ramp block 19 forms a sliding structure with the electrode body 3 through the slider, and the convex head 20 is made of rubber.

In specific implementation, the electromagnetic clutch is a device that controls the start, stop and braking of the motor in the mechanical transmission system. When braking is performed through the electromagnetic clutch, the friction plate 4 needs to be in contact with the electrode plate 5, and the two generate friction for braking. After long-term use, the friction plate 4 will be worn. In order to ensure the braking effect of the friction plate 4, it is necessary to compensate for the wear of the friction plate 4. By rotating the rotating ring 16, the rotating ring 16 will squeeze the pressure rod 18 through the internal extrusion groove 17 when it moves, so that it moves. When the pressure rod 18 moves, it will squeeze the inclined block 19 to move it to the outside of the electrode body 3, thereby compensating for the wear. The amount of wear of the friction plate 4 can be compensated. When the rotating ring 16 rotates, the rubber convex head 20 will be driven to move. The convex head 20 will be deformed and disengaged from the first groove 21. The rotating ring 16 continues to rotate. When the rotating ring 16 drives the convex head 20 to rotate to the position of the second groove 22, the shape of the convex head 20 will be restored and engaged with the second groove 22. At this time, the position of the rotating ring 16 will be fixed, and the friction plate 4 will not be able to move back to the inside of the electrode body 3, thereby completing the compensation for the wear of the friction plate 4. In this way, the above operation can facilitate the compensation for the wear of the friction plate 4 in the electromagnetic clutch brake device and maintain the braking effect of the friction plate 4.

To sum up: when using the electromagnetic clutch brake device, first, the coil 2 is energized through the cable. After the coil 2 is energized, a magnetic circuit will be formed through the electrode body 3, which will attract the electrode plate 5. When the electrode plate 5 moves and contacts the friction plate 4, friction will be generated, and the connecting shaft 6 will be braked. After the coil 2 is powered off, the magnetic circuit will disappear. At this time, the spring 7 will push the electrode plate 5 to break away from the friction with the friction plate 4. This is the characteristic of the electromagnetic clutch brake device.
