With the development of computer technology and information technology , product development of parametric CAD system has become an inevitable trend of enterprise product digitization of information , establish parametric Gallery , automatic assembly of the parts is of urgent need . This research work to make up for the general lack of CAD software parameterized building a database function to simplify the tedious , repetitive assembly work has important practical significance . Based on the widespread use of domestic CAD / CAM software Pro / ENGINEER ( referred to as Pro / E) as a platform , a variety of Pro / E secondary development tools - clustered tables ( Family Table ) , user-defined characteristics ( UDF ) , the Program , J-link and Pro / TOOKIT , were analyzed and compared . Determine the secondary development of Pro / E , Pro / TOOLKIT secondary development of key technologies such as interface design , database design , interface design, and create a Pro / TOOLKIT application , Pro / E and MFC communication research and exploration . Second, the proposed method of one implementation of the automated assembly of the parts . On the basis of the application of automatic assembly theory , the study of the key technologies of automatic assembly using Pro / TOOLKIT prepared automatic assembly function , and thus complete the automated assembly of parts in Pro / E environment . Finally , this paper research design and development of a gondola parameterized automatic assembly system . Through the system , users can design visualization platform various parts of the gondola , while achieving the automatic assembly of parts , not only to avoid the repeatability of similar parts design , improve design efficiency and design quality , shorten product the development cycle , but also to facilitate the subsequent finite element analysis , in line with the development of modern design , has a high value in use and application prospects .
