[Abstract]:Automatic drilling and riveting is an important way to improve the quality and efficiency of aircraft assembly. As a key technology of automatic drilling and riveting off-line programming has become a hot spot in the field of aviation assembly at home and abroad. Compared with teaching programming, offline programming is more flexible and can be used for more complex processing task planning. In this paper, the off-line programming and simulation technology of automatic drilling and riveting machine for aircraft components is studied in combination with the actual project requirements. The main research contents are as follows: (1) according to the structure and working principle of the automatic drilling and riveting machine for aircraft parts, The task planning requirements of each process equipment in off-line programming are analyzed in detail. On this basis, the overall scheme of off-line programming system design is proposed. (2) the data source of off-line programming is analyzed. This paper puts forward a method of establishing process digital model of fuselage product by combining two secondary development methods of UDFU Automation. On the basis of this, the method of extracting and managing process information of product is studied. (3) from machine tool, In this paper, the main tasks of off-line planning are described in terms of end effector and turntable, and the division of turntable stations is put forward. The machining path planning of hole position and the method of realizing machining process planning by associating hole position process information with process database are discussed. (4) the method of automatically establishing dynamic simulation of machine tool system by NC code of machine tool under Delmia platform is discussed. The kinematics model of machine tool is defined, the detection and processing method of simulation interference collision is studied, and the post processing method of simulation task is proposed.
