Research On Automatic Assembly Technology And Application In Modular Restructuring Based On Pro/E Secondary Development

With the increasment of the personalized product’s customized demand, the customized development of common software has become a powerful tool for the formation of product competitiveness in improving product design efficiency. The paper research automatic assembly technology based on Pro/E secondary development and its application in modular restructuring, it can make an important practical significance in making better assembly function of Pro/E system, simplifying the tedious and repetitive assembly work in modular restructuring so as to improve assembly efficiency.The paper research related basic knowledge of Pro/E secondary development firstly. Took Pro/Toolkit as the secondary development method through the comparative analysis among several development methods, introduced the operating mode and basic grammar of Pro/Toolki、the process of creating Pro/Toolkit application the Pro/E menu customization and system dialog design.The paper research the key technology and logical process of realizing automatic assembly based on Pro/E secondary development. Summarized the essence of realizing automatic assembly, research the key technology such as the expression of assembly model tree、the expression and acquisition of component location、the acquisition of component datum feature、the component constraint imposed and so on. And take the radar slip ring as an example, introduced the implementation of its automatic assembly.In order to describle the structural characteristic of modular product more intuitive, and make a full use of the knowledge composition of modular product, the paper proposed a modular restructuring method based on knowledge reuse. The paper describled the knowledge base composition of modular product, realized modular matching through modular matching relation base、modular relationship adjacency matrix and modular matching searching algorithm, realized the conversion from interface constraint to geometric constraint through interface constraint base, round cut interface location and constraint conversion algorithm, describled the application idea of automatic assembly in modular restructuring and the data connection between them.The paper analyzed the structural characteristics of radar slip ring, established the technical program of the automatic assembly modular restructuring system, and make a detailed description of the system design and operation process.Through the above research, the paper developed the automatic assembly modular restructuring system of a certain type radar slip ring. Through the system, designers can quickly form the main structure of radar slip ring corresponding with the certain customer need, completed the automatic assembly function of radar slip ring and improve the design efficiency, it has a great value in terms of engineering practice.
