摘要
飞机机身与机翼大部件对接及孔精加工任务,存在装配对象质量大、所需精加工孔数量多、需要在总装现场进行加工等难点。为解决上述问题,设计了一种飞机大部件对接及精加工系统。在数字化测量系统的定位下,AGV平台装载运输机翼大部件,配合位姿定位系统进行机翼与机身的调姿对接,由孔精加工系统完成孔的精加工。经试验验证,系统的定位误差小于行程的0.1%,精加工孔的尺寸精度满足IT7精度。大批量孔精加工试验中,对接与精加工150个孔用时总计36 h,验证了其部署于实际生产线中的可行性。
The tasks of docking the aircraft wing parts and finishing holes have difficulties such as the quality of the assembly object,the number of finishing holes required,and the need for processing at the assembly site.In order to solve the above problems,a docking and finishing system for large aircraft parts is designed.Under the positioning of the digital measurement system,the AGV platform loads and transports the large parts of aircraft wing,and cooperates with the posture positioning system to perform the posture adjustment and docking of the wing and the fuselage,and the hole finishing system finishing the holes.After experimental verification,the positioning error of the system is less than 0.1%of the stroke,and the dimensional accuracy of the finished hole meets the IT7 accuracy.In the large-scale hole finishing,it takes 36 h for docking and finishing a total of 150 holes,which confirms the feasibility of deploying in the actual production line.
