[0040] The intermittent switch 614 mechanism includes a motor 602, a connecting frame 603, a power supply 601, a switch 614, and an intermittent rotation assembly. The switch 614 and the pressing plate 606 are on the same horizontal plane, so when the pressing plate 606 rotates to the vicinity of the switch 614, it can press the switch 614 to turn on the power supply 601. The power supply 601 is located on the top of the mounting platform 2, the switch 614 is located on the front of the power supply 601, the connecting frame 603 is located on the side of the power supply 601, and the motor 602 is located inside the connecting frame 603.

[0041] Example 2

[0042] like Figures 5-6 As shown, the present invention proposes an automatic detection device for dynamic engagement of an electromagnetic brake. Compared with Embodiment 1, this embodiment details the structure of the dust removal mechanism.

[0043] The dust removal mechanism includes a connecting frame 702, a motor 701, a rotating shaft 703, a rotating shaft 711, a striking component, and an air blowing component. The connecting frame 702 is located on the top of the base 1, the motor 701 is located inside the connecting frame 702, the rotating shaft 703 is located at the output end of the motor 701, and the rotating shaft 711 is located at the end of the motor 701 away from the rotating shaft 703. The striking component is located at the end of the rotating shaft 711 away from the motor 701 and is used to intermittently strike the electromagnetic brake body 4. The air blowing component is located at the end of the rotating shaft 703 away from the motor 701 and is used to continuously generate airflow to blow onto the electromagnetic brake body 4. The striking assembly includes a rotating rod 712, a power rod 713, a mounting plate 718, and a striking rod 716. The rotating rod 712 is located at the end of the rotating shaft 711 away from the motor 701. The power rod 713 is located at the end of the rotating rod 712 away from the rotating shaft 711. The mounting plate 718 is snapped onto the top of the electromagnetic brake body 4. The striking rod 716 is slidably mounted on the top of the mounting plate 718. A connecting plate 715 is provided on the top of the striking rod 716. A lifting block 714 is provided at the end of the connecting plate 715 away from the striking rod 716. The bottom of the lifting block 714 is located on the circular motion trajectory of the power rod 713, and one side of the lifting block 714 is set as an arc surface to facilitate upward lifting after contact with the power rod 713. A spring 717 is provided on the top of the mounting plate 718. The top of spring 717 is connected to the end of connecting plate 715 and is located outside the striking rod 716. When motor 2 701 is started, motor 2 701 drives shaft 3 711 to rotate. Shaft 3 711 drives power rod 713 to rotate through rod 3 712. After power rod 713 contacts lifting block 714, it presses lifting block 714 upward, thereby causing lifting block 714 to move upward. Lifting block 714 moves upward through connecting plate 715. Connecting plate 715 drives striking rod 716 to move upward. At this time, spring 717 is compressed. When power rod 713 disengages from lifting block 714, spring 717 quickly rebounds, thereby driving striking rod 716 to move downward and strike the friction disc of electromagnetic brake body 4, vibrating down impurities that are difficult to clean from the friction disc.The air blowing assembly includes a pressing rod 704, a connecting pipe 708, a transfer box 709, and an air blowing pipe 710. The pressing rod 704 is located at the end of the rotating shaft 703 away from the motor 701. The connecting pipe 708 is located on the side of the airbag 707. The transfer box 709 is located at the end of the connecting pipe 708 away from the airbag 707. The air blowing pipe 710 is located on the side of the transfer box 709, and there are two symmetrically arranged air blowing pipes 710 in the transfer box 709. The air blowing pipe 710 is located away from the transfer box. One end of 709 points to the friction disc of the electromagnetic brake body 4, which facilitates the cleaning of dust and impurities on the friction disc. Motor 2 701 drives the rotating shaft 2 703 to rotate, and the rotating shaft 2 703 drives the pressing rod 704 to rotate. When the pressing rod 704 contacts the extrusion plate 706, it will squeeze the air bag 707, thereby generating airflow. The airflow is blown out from the air blowing pipe 710 through the connecting pipe 708 and the transfer box 709, thereby cleaning the friction disc on the electromagnetic brake body 4.

[0044] In summary, when using this utility model, the electromagnetic brake body 4 to be tested is snapped onto the mounting arc plate 5. Then, the rotating wheel 3 is installed at the end of the rotating shaft 711, and motors 602 and 701 are started. Motor 602 drives the rotating shaft 604 to rotate, which in turn drives the rotating rod 607 to rotate. The rotating rod 607 drives the end of the lever 609 to rotate slightly through the fixed shaft 608, thereby causing the lever 610 to intermittently move the intermittent rotating disk 605, causing the intermittent rotating disk 605 to rotate on the rotating shaft 604. When the pressing plate 606 rotates to the vicinity of the switch 614, it presses the switch 614, thereby turning on the power supply 601 to supply power to the electromagnetic brake body 4. When the switch 614 is released, the power supply 601 is turned off. This process is repeated to intermittently switch the power supply 601 on and off, thereby causing the electromagnetic brake body 4 to intermittently start and brake the rotating wheel 3. Motor 701 drives the rotating shaft 703 to rotate, and the rotating shaft 709 rotates... 3. The pressing rod 704 is driven to rotate. When the pressing rod 704 contacts the extrusion plate 706, it will compress the air bag 707, thereby generating airflow. The airflow is blown out from the air blowing pipe 710 through the connecting pipe 708 and the transfer box 709, thereby cleaning the friction disc on the electromagnetic brake body 4. At the same time, the second motor 701 can also drive the third rotating shaft 711 to rotate. The third rotating shaft 711 drives the power rod 713 to rotate through the third rotating rod 712. After the power rod 713 contacts the lifting block 714, it presses the lifting block 714 upward, thereby causing the lifting block 714 to move upward. The lifting block 714 moves upward through the connecting plate 715. The connecting plate 715 drives the striking rod 716 to move upward. At this time, the spring 717 is compressed. When the power rod 713 is separated from the lifting block 714, the spring 717 quickly rebounds, thereby driving the striking rod 716 to move downward and strike the friction disc of the electromagnetic brake body 4, vibrating down the impurities that are difficult to clean on the friction disc.

[0045] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
