Electromagnetic-triggered pressing and releasing device and using method

Abstract

The invention relates to the technical field of spaceflight, in particular to a using method of an electromagnetically-triggered pressing and releasing device which comprises a support, a pin shaft hole is formed in the support, and a pin shaft is arranged in the pin shaft hole; a spring retainer ring is arranged in the pin shaft; and a first spring is arranged on the inner side of the spring check ring. The locking mode is more reliable, the pin shaft is manually pushed to be inserted into the external fixed part until the limiting block is in contact with the support seam, and at the moment, the external part is completely pressed; meanwhile, the spring check ring is pulled out of the pin shaft without limitation, and the spring check ring is driven by the insertion rod to expand to abut against the left end of the pin shaft at the moment, so that the pin shaft is limited, the pin shaft and the spring check ring form a rigid pin, and it is guaranteed that an external component is completely pressed and fixed; compared with a single-pull-pin release mode in the prior art, more space is saved through a mode that the spring retainer ring and the pin shaft are sleeved, shrunk and released.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a method for using an electromagnetically triggered compression release device. Background technique [0002] In the field of aerospace technology, spacecraft compression release devices are widely used. The spacecraft compression release device is used to provide compression constraints for the spacecraft accessories during the launch phase of the spacecraft; after the spacecraft enters orbit, release the constraints on the accessories according to the instructions. [0003] Although the traditional pyrotechnic trigger method is reliable in separation and short in actuation time, it also has the disadvantages of large impact load after triggering, obvious safety hazards and only one-time use; the invention solves the problem of pyrotechnic device-based When the compression release device works, it will produce a large impact load, obvious safety hazards and technical problem...

Problems solved by technology

[0003] Although the traditional pyrotechnic trigger method is reliable in separation and short in actuation time, it also has the disadvantages of large impact load after triggering, obvious safety hazards and only one-time use; the invention solves the problem of pyrotechnic device-based When the compression and release device works, it will produce a large impact load, obvious safety hazards and technical problems that can only be used once. It has the advantages of simple structure, safety and reliability, low impact, no pollution and reusability.
