The invention provides a backlash compensation method based on a three-dimensional scanning measurement technology, and belongs to the field of aircraft assembly. The method comprises the following steps: firstly, respectively carrying out three-dimensional scanning on a wallboard and a skeleton to obtain actual outer contour data; performing comparative analysis with a theoretical mathematical model, determining the type and the position of the gap, and measuring the size of the gap; formulating a backlash compensation scheme; and finally, backlash compensation and assembly are carried out. According to the invention, the outline characteristics of the skeleton are quantified through digital measurement, the assembly quality of the skeleton is optimized, and interference and gaps are avoided in advance; the screening efficiency and quality are greatly improved; a hole making connection area suitable for being used as skin pre-positioning can be accurately judged, and secondary error accumulation caused by positioning at an out-of-tolerance position is avoided; the accuracy of compensation material adding is improved, the assembly process is simplified, and the efficiency is improved.

    本发明提供了一种基于三维扫描测量技术的间隙补偿方法,属于属于飞机装配领域。首先,对壁板及骨架分别进行三维扫描,得到实际外轮廓数据;与理论数模进行比对分析,确定间隙类型和位置,并测量间隙大小;制定间隙补偿方案;最后进行间隙补偿及装配。本发明通过数字化测量量化了骨架外形特征,优化了骨架装配质量,提前避免了干涉和间隙的产生;极大地提高了筛查效率与质量;能准确判断出适合作为蒙皮预定位的制孔连接区域,避免在超差位置定位造成的二次误差累积;提升了补偿材料添加的准确度,简化了装配流程,提高了效率。
