To improve the quality and efficiency of the information management of aircraft assembly process, the integrated management system is used to control and manage the aircraft assembly flexible assembly to realize the integration of aircraft assembly process. In this paper, the integrated management system in the application of flexible aircraft assembly fixtures, the architecture of integrated management system, data format and communication interface are summarized, such as data transmission and adjustment of flexible fixture after driving process is analyzed, and to summarize the plane flexible assembly technology system, finally, the present situation of the application of integrated management system on the flexible fixture were studied. Through the research, the integrated management system can improve the assembly efficiency and information management quality of flexible tooling.
