The invention relates to the technical field of civil aircraft C919 main undercarriage maintenance equipment, and discloses C919 main undercarriage inner cylinder mounting equipment which comprises a bottom frame assembly, a course adjusting assembly, a course angle adjusting assembly, a manual hydraulic lifting assembly, a spanwise adjusting assembly, a hoop assembly and a safety locking device. An inclinometer is arranged on the side face of the course angle adjusting assembly; the bottom frame assembly comprises a welding frame, a handrail and a rail for guiding the course adjusting assembly are welded to the welding frame, and a first universal wheel and a second universal wheel are arranged at the bottom of the welding frame. Through precise mechanical adjustment and an auxiliary system, the assembly process of the inner barrel and the outer barrel of the main landing gear is more precise. Through the synergistic effect of the course adjusting assembly, the course angle adjusting assembly and the spanwise adjusting assembly, accurate adjustment of the inner cylinder in multiple directions can be achieved, it is ensured that the inner cylinder and the outer cylinder are coaxial and concentric, and the assembly precision and efficiency are improved.

    本发明涉及民用航空器C919主起落架维修设备技术领域,公开了C919主起落架内筒安装设备,包括底框组件、航向调节组件、航向角度调节组件、手动液压升降组件、展向调节组件、抱箍组件和安全锁定装置,所述航向角度调节组件的侧面设置有倾角仪;所述底框组件包括焊接框架,所述焊接框架上焊接设置有扶手和为航向调节组件提供导向的轨道,所述焊接框架的底部设置有万向轮一和万向轮二,本发明通过精确的机械调节和辅助系统,使得主起落架内筒与外筒的组装过程更加精确。通过航向调节组件、航向角度调节组件和展向调节组件的协同作用,能够实现内筒在多个方向上的精准调整,确保内筒和外筒同轴、同心,提高了装配精度和效率。
