Abstract


High precision servo turntable is complex products of light mechanical and electrical integration. Widely used in all kinds of complex and precision instruments, the structure is complex and changeful. It is difficult to meet the requirements for the traditional turntable assembly process planning. The amount of physical prototype test equipment seriously affects the development of the time and cost of turntable. This paper developed for a high precision servo turntable assembly process planning in virtual assembly system.According to the characteristics of assembly process of high precision servo turntable, developed the overall scheme of virtual assembly system in this paper. Using the MFC to design the operation interface of system. Three-dimensional environment of system is generated by OpenGL.It is implemented successfully reconstruction of the rotary parts in the system through parts of VRML file analysis and modeling software Solidworks two development. The use of C++and C language to build the assembly relation database and the geometric constraint recognition algorithm, Implements the system of parts for assembly assembled relationship and geometric constraint relationship. The establishment of three coordinate system model to realize geometry assembly operation movement, completed parts of the precise positioning table, adopting the interactive model in virtual assembly system to operate assembly simulation, and records of the assembly sequence and path of the assembly. The assembly yield function to generate the assembly sequence and path were assessed and obtained the most reasonable assembly process.The turntable assembly process is planned through the virtual assembly. Planning the most reasonable assembly process and assembled for turntable in reality. The results show that Use of high precision servo turntable virtual assembly system for turntable assembly process planning can effectively improve the system development cycle and development cost.
