摘要

基于机器人的蒙皮在线制孔自动加工成功地解决了传统制孔效率低与质量差的问题,逐渐在飞机装配中得到广泛应用。针对其采用在线测量方式精度有限,通过精确的制孔质量的分析与检验来实现制孔工艺的评估十分必要。以制孔质量检验分析为目标的测量规划,实现基于三坐标测量机的检验特征的数据采集。设计简单几何形状与复杂曲面特征的建模方法,完成检验特征的几何模型重构。提取质量分析关联几何信息,建立质量分析评价模型,完成综合评价指标的计算。实验结果表明,该方法满足制孔质量的高精度综合评价需求,为制孔工艺的完善提供可靠的分析数据。

Abstract

Automatic processing of online hole making for skin based on robot has successfully solved the problems of low efficiency and poor quality in traditional hole making and has been widely used in aircraft assembly.Due to the limited accuracy of on-line measurement, it is necessary to evaluate the hole making process by analyzing and inspecting the hole making quality accurately.The measurement planning is aimed at the quality inspection analysis of hole making, and the data collection based on the inspection characteristics of CMM is realized.The modeling method of simple geometric shape and complex surface features is designed, and the geometric model reconstruction of test features is completed.The correlative geometric information of quality analysis is extracted, the evaluation model of quality analysis is established, and the comprehensive evaluation index is calculated.The experimental results show that this method can meet the requirement of high precision comprehensive evaluation of hole making quality and provide reliable analytical data for the improvement of hole making process.
