Research on Assembly Location Method of Cable Harness Based on Hierarchical Model

为了提高飞机线束的装配效率和装配质量,提出了确定线束装配定位方法的总体流程,通过提取线束3D模型数据信息,建立了基于父子分支的线束层次数据链模型。提出一种新的线束展平角计算方法,并按照线束层次模型将线束进行展平,最终在2D展平图上确定出线束安装定位标记的位置,通过编程在MATLABGUI中搭建了装配定位平台,实验表明,该方法能够在制造出的线束上进行标记,可以指导生产以及现场装配。

To improve the assembly efficiency and quality of the aircraft cable harness,the overall process of the cable assembly location system is proposed.By extracting the 3D model data of the cable harness,this paper establishes a hierarchical data model of cable harness based on the father-son branch,proposes a new method of calculating the flattening angle of the cable harness and flattens the cable harness according to the hierarchical model,and then determines the position of assembly locating mark on the 2D flattening graph.The assembly location platform is set up in the MATLAB GUI,and the experimental result shows that the method can be used to provide marks on the cable harness and guide the production and assembly on site.
