The invention discloses a multi-stage buffer device for separation of firework parts for spaceflight, and belongs to the technical field of spaceflight separation. A sleeve and a sliding assembly are arranged to connect a connecting plug spaceflight part and a throwing piece, the throwing piece obtains energy at the moment of firework separation and flies out at the initial speed, and a supporting plate and a supporting column connected with the throwing piece are stressed and extruded, so that the throwing piece is separated from the spaceflight part. The sliding seat extrudes the telescopic air bag cushion, the telescopic air bag cushion can guide air into the piston cylinder through the air guide pipe after being compressed so that the piston rod can extend, meanwhile, the gear rotates under the action of the tooth groove, the torsional spring provides a reverse acting force, and therefore the connecting plug spaceflight piece is buffered, and the fixing frame is reversely supported in cooperation with the piston rod; according to the technical scheme, the purpose of elastic damping can be achieved, the connecting plug spaceflight piece is protected in a multi-stage buffering mode, the situation that due to the fact that the buffering effect is affected by dragging limitation between the connecting plug spaceflight piece and the throwing piece, the part deforms is prevented, the hot work separation efficiency is improved, and meanwhile the use potential safety hazards are reduced.
本发明公开了一种航天用火工部件分离多级缓冲装置,属于航天分离技术领域,通过设置套筒和滑动组件来连接插接头航天件和抛片,抛片火工分离瞬间获能产生初始速度飞出,抛片所牵连的支撑板和支撑柱则受力被挤压,滑动座则挤压伸缩气囊垫,伸缩气囊垫被压缩后能够将气体通过导气管导入活塞筒内使活塞杆伸长,同时齿轮在齿槽的作用下发生旋转,使扭簧提供一个反向作用力,从而对插接头航天件进行缓冲,配合活塞杆对固定架进行反向支撑,能够实现弹性阻尼的目的,通过多级缓冲的方式对插接头航天件进行保护,防止插接头航天件与抛片之间因拖拽限制影响缓冲效果从而造成部件出现形变情况,提高火工分离效率的同时降低使用安全隐患。
