激光投影技术在装配连接中的应用

Application of Laser Projection Technology in Assembly Connection

在飞机部件装配中,装配连接孔位主要以人工画线和样板画线的方式确定,工作效率低下。针对部件表面装配连接孔位,利用计算机辅助制造软件提取所需投影部件的连接孔位及投影面,分析、研究激光投影设备通过捕捉部件装配型架或部件自身的基准点,将理论连接孔位及理论投影面快速、准确投影至部件实际投影面的方法。

In traditional aircraft part assembly, the position of connecting hole is mainly determined by the method of manual drawing line and the pattern line, whose efficiency is very slow. Aiming at the surface assembly connection hole position of the component, using CAM systems to extract the position of connecting hole and projection plane of the required projection parts, through the capturing of part assembly fixture or parts of their own reference points with laser projection equipment, a fast and accurate projection to the actual projection surface of the part is used to connect the theoretical connection hole position and the theoretical projection plane.
