A separating and avoiding integrated large-bearing high-reliability locking and releasing device comprises an upper end fixing adapter, a grooving bolt assembly, two side pressing plate assemblies and a bottom fixing seat. The two side pressing plate assemblies are oppositely fixed to the bottom fixing base, and the upper end fixing adapter base is fixed to an upper end opening formed by the two side pressing plate assemblies. The grooving bolt assembly penetrates through the through holes of the two side pressing plate assemblies, and a weakening groove is machined in the portion, located between the two side pressing plate assemblies, of the grooving bolt assembly. The upper end fixing adapter is fixedly connected with the optical pointing mechanism, and the bottom fixing base is fixedly connected with a satellite deck; and after reaching a preset orbit, the grooving bolt assembly pulls off the two side pressing plate assemblies to be opened towards the two sides, so that release between the optical pointing mechanism and the satellite cabin plate is realized. According to the invention, the locking and releasing device has separation and avoidance integration, so that a non-firer type locking and releasing device can meet the task capability of integration of impact resistance, locking and avoidance functions with a small single-machine total weight.
一种分离和避让一体化大承载高可靠锁紧释放装置,包括上端固定转接座、切槽螺栓组件、两个侧压板组件以及底部固定座;两个侧压板组件相对固定在底部固定座上,上端固定转接座固定在两个侧压板组件形成的上端开口处;切槽螺栓组件穿过两个侧压板组件的通孔,且位于两个侧压板组件之间的部分加工有削弱槽。上端固定转接座与光学指向机构进行固定连接,底部固定座与卫星舱板进行固定连接;到达预定轨道后,切槽螺栓组件拉断两个侧压板组件向两侧张开,实现光学指向机构与卫星舱板之间的释放。本发明使锁紧释放装置具备分离和避让一体化,实现了非火工类锁紧释放装置以较小单机总重,满足抗冲击、锁紧及避让功能一体化的任务能力。
