基于误差实时检测自动钻铆编程方法研究

摘要

自动钻铆已逐渐成为飞机装配过程中最常见的自动化装配工艺方法.但由于具有弱刚性、薄厚度等特点,壁板在自动钻铆过程中将不可避免的发生变形,为有效控制变形,基于被加工壁板尺寸、厚度、曲率变化等结构特点,建立了一种误差实时监测与反馈方法,构建自动钻铆系统的三坐标误差补偿算法,并融入编程过程中,在代码执行过程中分析理论模型与实物模型间的对应关系,完成误差的实时补偿,提高钻铆效率与质量.%In recent years,with the development of aerospace technology,the aircraft quality and performance and its assembly precision are improved greatly.Because the aircraft assembled by use of automatic drilling and riveting technology is characteristic of good quality and stability,this way replaces the traditional way of hand-drilling and riveting in aircraft assembly process,and is widely used for aircraft assembly,but the serious problems of panel deformation and low efficiency exist in the drilling and riveting process.This article instals real-time error measuring means and feedback mechanism according to the structural characteristics of component size,thickness and curvature change,eatablishes a three coordinate error compensation algorithm and analyzes the correspondence relationship between the theoretical model and physical model,based on the theory of least square method,in order to improve the drilling and riveting efficiency and quality.
