The invention provides an aircraft landing gear automatic assembly method based on a high-precision rapid scanning technology, and belongs to the field of aircraft landing gear assembly. According to a high-precision rapid scanning measurement system and a data analysis processing system, a relative coordinate system is established, axis parameters of upper and lower mounting hinge points of a body structure and axis parameters of an undercarriage mounting shaft are calculated, whether two axis direction vectors are collinear vectors or not and whether important key points coincide or not are calculated in real time, and the accuracy of undercarriage positioning is improved. And the multi-degree-of-freedom rocker arm robot calibrates the position posture of the undercarriage in real time according to the calculation result and the scanning position parameters. According to the invention, the attitude of the undercarriage can be automatically calibrated in real time, and the position information of the undercarriage is monitored, so that the interference condition between the undercarriage and the structure is avoided; according to the multi-degree-of-freedom rocker arm robot, complicated manual operation procedures are avoided. High-precision, high-efficiency and high-quality automatic assembly of the aircraft landing gear can be achieved, and the rhythm of aircraft pulsation production is guaranteed.

    本发明提供一种基于高精度快速扫描技术的飞机起落架自动装配方法,属于飞机起落架装配领域。本发明根据高精度快速扫描测量系统和数据分析处理系统,建立相对坐标系,计算机体结构上下安装铰点轴线参数以及起落架安装轴轴线参数,实时计算两条轴线方向向量是否为共线向量,以及重要关键点是否重合,多自由度摇臂机器人根据计算结果及扫描位置参数,实时校准起落架位置姿态。本发明可实现对起落架姿态的实时自动化校准,并兼顾监测起落架的位置信息,以避免起落架与结构之间的干涉情况;本发明中涉及的多自由度摇臂机器人,避免了繁杂的人工操作流程。本发明可实现飞机起落架高精度、高效率、高质量的自动化装配,保证了飞机脉动生产的节奏。
