The invention relates to the technical field of unmanned helicopters, and discloses an unmanned helicopter mechanical operation arm with telescopic length, the unmanned helicopter mechanical operation arm with telescopic length comprises a machine body, a mounting base is fixedly mounted at the bottom of the machine body, a movable arm is movably arranged at the bottom of the mounting base, and the tail end of the movable arm is movably connected with an outer cylinder; and a telescopic cylinder is movably arranged on the inner wall of the outer cylinder. A motor is fixedly mounted on the inner top wall of the outer cylinder, and a telescopic mechanism is arranged between the tail end of an output shaft of the motor and the telescopic cylinder so that the telescopic cylinder extends into and out of the outer cylinder. The motor operates to drive the lead screw at the top of the output shaft to rotate, the lead screw rotates to drive the nut in threaded connection with the outer wall of the lead screw to move up and down, the nut moves up and down to drive the telescopic cylinder to move back and forth through the connecting piece, the telescopic cylinder retracts into the outer cylinder or stretches out of the outer cylinder, and thus the stretching length of the telescopic cylinder can be adjusted conveniently, and practicability is higher; and when the telescopic cylinder stretches out, grabbing is facilitated, and when the telescopic cylinder retracts, landing of the unmanned helicopter is facilitated.
本发明涉及无人直升机技术领域,且公开了一种无人直升机用可伸缩长短机械操作臂,包括机体,所述机体的底部固定安装有安装座,所述安装座的底部活动设置有活动臂,所述活动臂的末端活动连接有外筒,所述外筒的内壁活动设置有伸缩筒。所述外筒的内顶壁固定安装有电机,设置在电机的输出轴末端与伸缩筒之间的伸缩机构,使伸缩筒在外筒内伸入伸出。电机运行带动其输出轴顶部的丝杆旋转,丝杆旋转带动其外壁螺纹连接的丝母上下移动,丝母上下移动通过连接片带动伸缩筒来回移动,使伸缩筒回缩进外筒中或从外筒中伸出,从而,也就便于调整伸缩筒的伸出长度,更具实用性,当伸缩筒伸出时,便于抓取,当伸缩筒回缩时,便于无人直升机的降落。
