The invention discloses a folding wing unfolding and locking device based on disc spring locking. The folding wing unfolding and locking device comprises a steering engine, a wing box, a bearing end cover, a wing rocker arm, a locking device, a locking pin, a folding combined disc spring, a guide rail, a sliding block, a connecting rod, a steering engine push rod connector, a rotating shaft and a bearing. In an initial state, the folding combined disc spring is in a free state, and when a wing rocker arm touches the inclined surface of the locking pin in the rotating process of a wing, the locking pin moves downwards under the action of normal force to pre-tighten the folding combined disc spring; when a locking hole in a wing rocker arm coincides with a first mounting hole, by utilizing the characteristics of high rigidity, quick deformation response and small impact force of the folding combined disc springs, the multiple sets of folding combined disc springs quickly push the locking pin to bounce into the locking hole by releasing stored elastic potential energy, so that the aim of quickly locking a wing is fulfilled; the folding wing unfolding and locking device is compact in structure, simple, reliable, quick in response, high in universality and capable of being applied to quick locking of airfoils of various aircrafts.

    本发明公开了一种基于碟簧锁紧的折叠翼展开锁定装置,包括舵机、翼盒、轴承端盖、机翼摇臂、锁定装置、锁止销、对合组合碟簧、导轨、滑块、连杆、舵机推杆接头、转动轴、轴承。初始状态时对合组合碟簧处于自由状态,当机翼转动过程中机翼摇臂触碰到锁止销斜面时,在法向力的作用下,锁止销向下运动,对对合组合碟簧进行预紧;当机翼摇臂上的锁定孔与第一安装孔重合时,利用对合组合碟簧刚度大、变形响应快、冲击力小的特点,多套对合组合碟簧通过释放储存的弹性势能,快速推动锁止销弹入锁定孔中,从而实现机翼快速锁紧的目的,本申请公开的折叠翼展开锁定装置结构紧凑、简单可靠、快速响应、通用性强,可应用于多种飞行器翼面快速锁定。
