The invention discloses an electromagnetic actuating pressing and releasing device, and belongs to the technical field of spaceflight, the electromagnetic actuating pressing and releasing device comprises a first shell, a second shell, a locking bolt and a locking nut, the first shell is provided with a first barrel for axial movement of the locking nut, and the first barrel is provided with a limiting structure for limiting circumferential rotation of the locking nut; the first shell is further provided with an electromagnetic actuating structure for locking the locking nut in the first cylinder; the second shell is provided with a second barrel for the locking bolt to axially move, the head of the locking bolt is limited to the end, away from the second shell, of the second barrel, and a screw of the locking bolt penetrates through the second barrel and is in threaded connection with the locking nut. The first shell and the second shell can be connected after the locking bolt and the locking nut are connected, then connection of the two parts is achieved, due to the fact that the locking nut is limited to rotate in the circumferential direction, pre-tightening torque can be applied when the locking bolt and the locking nut are connected, and therefore the connection stability of the two parts is improved.

    本发明公开了一种电磁致动压紧释放装置,属于航天技术领域,包括第一壳体、第二壳体、锁紧螺栓和锁紧螺母,第一壳体设置有供锁紧螺母轴向移动的第一筒体,第一筒体设置有限制锁紧螺母周向转动的限位结构,第一壳体还设置有将锁紧螺母锁紧在第一筒体内的电磁致动结构;第二壳体设置有供锁紧螺栓轴向移动的第二筒体,锁紧螺栓的头部限定于第二筒体远离第二壳体的端部,锁紧螺栓的螺杆贯穿第二筒体并螺纹连接锁紧螺母。本发明能够在锁紧螺栓与锁紧螺母连接后实现第一壳体与第二壳体的连接,进而实现两部件的连接,由于锁紧螺母被限定周向转动,能够在连接锁紧螺栓和锁紧螺母时,施加预紧力矩,从而提高两部件的连接稳定性。
