The invention discloses a rotor blade folding and locking driving device, and relates to the technical field of mechanical rotors. According to the technical scheme, the main function of the driving device with the lock is that when a driving program is started, firstly, an axial lock pin extends out, axial locking is achieved, movement of a specific structure is limited, and after axial locking is completed, a piston rod is driven to drive the specific structure to move; when the reverse drive program is started, the axial lock pin retracts, axial unlocking is achieved, movement of the specific structure 1 is relieved, and after axial unlocking is completed, the piston rod is driven to drive the specific structure to move. Besides, in the locking and unlocking process of the axial lock, the microswitch is triggered through the lock pin, a signal indicating whether the axial lock is unlocked or not is given out, and normal operation of the system can be supported together with signal switches of other components. Through reasonable structural layout, the axial locking mechanism and the driving actuating cylinder are effectively integrated. Locking and driving sequential actions are achieved, and the control logic is simple. And the rotor wing can be quickly folded.

    本发明公开的一种旋翼桨叶折叠上锁驱动装置,涉及机械旋翼技术领域。本发明通过下述技术方案实现:带锁驱动装置的主要功能是在启动驱动程序时,首先轴向锁锁销伸出,实现轴向上锁,限制特定结构的运动,完成轴向上锁后,驱动活塞杆带动特定结构运动;在启动反驱动程序时,轴向锁锁销缩回,实现轴向解锁,解除特定结构1的运动,完成轴向解锁后,驱动活塞杆带动特定结构运动。另外,轴向锁上锁和开锁的过程中,通过锁销触发微动开关,给出轴向锁是否开锁的信号,可与其他部件的信号开关一起共同支持系统的正常运作。通过合理的结构布局,有效地将轴向锁止机构和驱动作动筒集成一体。具有上锁与驱动顺序动作,控制逻辑简单。能够实现旋翼快速折叠。
