An electromagnetically triggered pressing and releasing device and its application method

Abstract

The invention relates to the field of aerospace technology, in particular to a method for using an electromagnetically triggered pressing and releasing device, comprising a support, a pin shaft hole is formed inside the support, and a pin shaft is arranged inside the pin shaft hole; A spring retaining ring is provided; the inner side of the spring retaining ring is provided with a spring 1; the locking method of the present invention is more reliable. At this time, the outer part is completely compressed; at the same time, the spring retaining ring can not be pulled out from the pin shaft. The limit of the pin shaft makes the pin shaft and the spring retaining ring form a rigid pin, so as to ensure the complete pressing and fixing of the external parts; the present invention uses the spring retaining ring and the pin shaft sleeve to shrink and release, compared with the prior art single-pull pin The release method saves more space.

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.
