The invention provides a parachute cutting device and an assembling method and a parachute cutting method thereof, and belongs to the technical field of aerospace. The parachute cutting device comprises a bottom plate, a telescopic pin shaft and a telescopic cutting device; the telescopic pin shaft and the telescopic cutting device are both installed on the bottom plate, and the telescopic directions of the telescopic pin shaft and the telescopic cutting device are both parallel to the plane where the bottom plate is located. The telescopic directions of the telescopic pin shaft and the telescopic cutting device are located in the same plane and are perpendicular to each other, when the first telescopic spring is in a stretched state and the second telescopic spring is in a compressed state, the limiting stopper and the limiting groove are matched in position and are in a locking state, and when the first telescopic spring is in a normal state, the limiting stopper and the limiting groove are in a locking state. The limiting stopper is used for being separated from the limiting groove. According to the parachute cutting device, the shape memory performance of the shape memory material is fully utilized, parachute cutting is completed, safety is high, environmental pollution cannot be caused, repeated use can be achieved, and the use cost is reduced.
本发明提供了一种降落伞切伞装置及其装配方法、切伞方法,属于航空航天技术领域,降落伞切伞装置包括底板、伸缩销轴和伸缩切割装置;伸缩销轴和伸缩切割装置均安装于底板上,且伸缩销轴和伸缩切割装置的伸缩方向均平行于底板所在的平面;伸缩销轴和伸缩切割装置的伸缩方向位于同一平面内且相互垂直,当第一伸缩弹簧处于拉伸状态,且第二伸缩弹簧处于压缩状态时,限位器和限位槽的位置相匹配,处于锁止状态,当第一伸缩弹簧处于正常状态时,限位器用于从限位槽中脱出。本发明提供的降落伞切伞装置充分利用了形状记忆材料的形状记忆性能,完成了降落伞切伞,安全性较高,不会导致环境污染,且能够多次使用,降低了使用成本。
