The invention provides a keel beam lifting and positioning system based on electric drive, which belongs to the technical field of aircraft assembly and comprises two groups of identical independent lifting systems, the two groups of identical independent lifting systems can form linkage and independently operate, and synchronous lifting and positioning and independent lifting fine adjustment are realized. Each independent lifting system comprises a right-angle hand-cranking speed reducer, a servo motor, a lifter push rod, supporting rods, a keel beam positioner and the like, the right-angle hand-cranking speed reducer is connected with the servo motor, the output end of the servo motor is connected with the lifter push rod to provide lifting power, and the supporting rods are arranged on the two sides of the lifter push rod and used for auxiliary supporting. And the keel beam positioner is used for positioning and locking the keel beam. The device is reliable in performance, and has relatively high overload capacity and relatively high precision; a double-system linkage design is adopted, the overall stability of the system is improved, and independent lifting can be achieved; an adjustable speed reducer is arranged, so that the lifting speed can be adjusted; the system is small in occupied space, simple in structure and convenient to operate; and the stroke protection function is achieved.

    本发明提供一种基于电驱动的龙骨梁升降定位系统,属于飞机装配技术领域,包括两组完全相同的单独升降系统,二者可以形成联动及单独运行,实现同步升降定位及单独升降微调,每个单独升降系统均直角手摇减速机、伺服电机、升降机推杆、支撑杆、龙骨梁定位器等,直角手摇减速机与伺服电机相连,伺服电机输出端与升降机推杆连接以提供升降动力,升降机推杆两侧设置支撑杆,用于辅助支撑,龙骨梁定位器用于定位并锁紧龙骨梁。本发明性能可靠,具有较大的过载能力和较高的精度;采用双系统联动设计,提高系统整体稳定性,且能够单独升降;配备可调式减速机,可调节升降速度;系统占用空间小,结构简单,操作便捷;具有行程保护功能。
