The electromagnet brake comprises a shell, a movable core assembly arranged in the shell in a sliding mode, an electromagnetic coil arranged in the shell and arranged outside the movable core assembly in a sleeving mode, and an end cover arranged at the end of the shell, the movable core assembly comprises a movable core main body arranged in the shell in a sliding mode and a movable core guide rod arranged at the end of the movable core main body, and the movable core guide rod is connected with the movable core main body in a sliding mode. An end cover opening is formed in the end cover, one end of the movable core guide rod is fixedly connected with the movable core main body, the other end of the movable core guide rod penetrates through the end cover opening and extends out of the end cover, and a magnetic isolation sheet and a buffer gasket are further arranged between the movable core main body and the end cover. Compared with the prior art, the electromagnetic valve is simple in structure and convenient to operate, the impact influence between the movable core assembly and the end cover when the electromagnetic valve is started is reduced by arranging the magnetism isolating sheet and the buffering gasket, starting noise is reduced, and the service life of the device is prolonged; and through the arrangement of the magnetic isolation sheet, the influence of magnetic residue of the electromagnetic coil after power failure is reduced, the reset speed of the movable core assembly is increased, and the brake response time is shortened.

    本发明涉及一种电磁铁制动器,包括壳体、滑动设于壳体内的动芯组件、设于壳体内并套设于动芯组件外的电磁线圈,以及设于壳体端部的端盖,其中,动芯组件包括滑动设于壳体内的动芯主体,以及设于动芯主体端部的动芯导杆,端盖上开设有端盖开孔,动芯导杆的一端与动芯主体固定连接,另一端穿过端盖开孔并伸出于端盖外,动芯主体与端盖之间还设有隔磁片与缓冲垫圈。与现有技术相比,本发明结构简单,操作方便,通过设置隔磁片与缓冲垫圈,以减少在电磁阀启动时动芯组件与端盖之间的撞击影响,减少启动噪音,延长装置使用寿命;并通过隔磁片的设置,降低断电后电磁线圈磁性残留的影响,提高动芯组件复位速度,减少制动响应时间。
