Application of Interference Analysis Based on Point Cloud Data in Automated Assembly of Instrument Supports

本文针对舱段内部仪器支架安装过程中，支架与筋条干涉影响自动化装配的问题，研究了一种基于点云数据的支架干涉分析与调整算法。通过分析支架角点与筋条的位置关系确定干涉现象，并根据分析结果对干涉支架的位置进行调整和补偿，指导后续自动化装配。以某舱段支架装配为例，利用该算法实现模型的自动装配。试验件装配结果表明，该算法有效、可靠，为舱段产品的自动化装配提供了重要手段。
In this paper, an interference analysis and adjustment algorithm of support based on point cloud data is studied to solve the problem that support and bar interference affect automatic assembly during the installation of instrument support in cabin. The interference phenomenon is determined by analyzing the position relationship between the corner point and the bar, and the position of the interference bracket is adjusted and compensated according to the analysis result, which guides the subsequent automatic assembly. Taking the assembly of a cabin support as an example, the algorithm is used to realize the automatic assembly of the model. Experimental assembly results show that the algorithm is effective and reliable, and provides an important means for automatic assembly of cabin products.
