【摘要】：飞机装配制造领域大量采用铆接作为零件之间的连接方式,传统的铆接以手工为主,其质量不易控制,劳动强度大,铆接效率底,正逐渐被自动钻铆机所取代。壁板组件是飞机装配的典型结构,其结构相对简单开敞,相对易于实现自动铆接,在飞机壁板组件制造中实现自动钻铆具有重要的实际意义。本文根据沈飞民机公司GRS6R30-96型号五轴自动钻铆机的原理和结构,建立了飞机壁板类组件的铆接流程,在对自动钻铆机和五轴数控托架系统分析的基础上,结合产品实际特征,制定各环节的解决方案后,建立了本文的飞机壁板全自动钻铆总体方案;根据某型号飞机壁板组件的结构特点,完成了一套壁板组件的自动钻铆工装研制;该工装简洁、有效,很好的解决了五轴钻铆机转角有限的问题;基于CATIA及其二次开发平台和Visual Basic,完成了GRS6R30-96型号五轴自动钻铆数控程序的开发,实现了壁板类组件铆接点与自动钻铆机铆接位置的自动约束,以及自动托架运行位置的自动测量,在西门子840D控制系统上实现了托架运行的自动控制;最终实现飞机壁板的全自动铆接。经过反复多次试验运行,重设自动钻铆机部分源代码,进一步提高了设备的加工效率。
[Abstract]:In the field of aircraft assembly and manufacturing, riveting is widely used as the connection between parts. The traditional riveting is mainly manual, its quality is not easy to control, labor intensity is large, riveting efficiency bottom is gradually replaced by automatic riveting machine. The panel assembly is a typical structure of aircraft assembly, its structure is relatively simple and open, and it is relatively easy to realize automatic riveting. It is of great practical significance to realize automatic drilling and riveting in the manufacture of aircraft panel assembly. According to the principle and structure of GRS6R30-96 five-axis automatic drilling and riveting machine of Shenfei Civil aircraft Company, this paper establishes the riveting flow of plane wall-plate components. Based on the analysis of automatic drilling riveting machine and five-axis numerical control bracket system, combined with the actual characteristics of the product, After the solution of each link is worked out, the overall scheme of automatic drilling and riveting for aircraft wall-plate is established in this paper. According to the structural characteristics of a certain type of aircraft wall-board assembly, a set of automatic drilling and riveting workpiece is developed, which is simple and effective. The problem of limited angle of five-axis drilling and riveting machine is well solved. Based on CATIA and its secondary development platform and Visual basic, the NC program of GRS6R30-96 model five-axis automatic drilling and riveting is developed. The automatic constraint of riveting point and riveting position of automatic drilling riveting machine is realized, and the automatic measurement of the running position of automatic bracket is realized. The automatic control of bracket operation is realized on Siemens 840D control system. Finally, the automatic riveting of aircraft wall plate is realized. After repeated tests, the automatic drilling riveting machine part of the source code, further improve the processing efficiency of the equipment.
