摘 要:定位检测是飞机机身部件自动化钻铆的技术基础,是提高系统定位精度的技术保证。根据大飞机机身筒段对接钻铆需求,研制了一套基于CCD相机定位检测的轻型自主移动钻铆系统。针对复杂加工系统和多样化基准形式,提出了多坐标系建立及转换方法和定位检测与加工任务自适应规划策略,通过检测不同基准位置,建立各坐标系关联,分别采用最小二乘法和间接转换法获得实际位置与理论位置的偏差模型,修正了待加工产品数模偏差和工装及产品制造与安装误差,对待加工孔位信息进行自适应规划。实验表明,定位检测方法切实可行,能实现系统高精度钻铆的精确定位。Positioning detection is technologically basic to automatic drilling and riveting of aircraft fuselage components,and it is used to provide the technical guarantee for improving the accuracy of the system positioning.According to the urgent need for butt drilling and riveting of large aircraft fuselage barrel segment,a lightweight autonomous mobile drilling and riveting system is developed based on CCD camera positioning detection.Aiming at the complex processing system and diversified reference forms,the establishment and transformation method of multi-coordinate system and the strategy for positioning detection and adaptive planning of processing tasks are proposed.The coordinate system correlation is established by detecting different reference positions,and the deviation model between the actual position and the theoretical position is obtained by the least squares method or the indirect conversion method respectively,so that the digital model deviation of the product to be processed and the manufacturing and installation errors of the tooling and the product are corrected.According to the adaptive planning,the hole position information is processed.Experimental results show that the positioning detection method is feasible and can be used to achieve precise positioning of the system with high precision drilling and riveting.
