The invention relates to the technical field of precise installation of aircraft joint parts, in particular to an aircraft wing body joint part machining allowance calculation method, which comprises the following steps: measuring wing body butt joint key feature points by measuring equipment to obtain measurement data; performing spatial fitting on the key features according to the measurement data; butting and fitting fuselage wings; and judging whether the machine body front joint needs to be repaired after butt joint, if so, calculating the machining allowance of the front joint, finishing after polishing, and if not, directly finishing. Through the method, the problems of high labor intensity, low working efficiency and low mounting precision can be effectively solved.

    本发明涉及飞机接头零件精准安装技术领域,特别是涉及一种飞机翼身接头零件加工余量计算方法,包括测量设备对翼身对接关键特征点进行测量,得到测量数据;根据测量数据对关键特征进行空间拟合;机身机翼对接拟合;判断机身前接头对接后是否需要修配,若是,计算前接头加工余量,进行打磨后结束,若否,直接结束。通过本方法,能有效解决劳动强度大、工作效率低和安装精度低的问题。
