Abstract:

In order to reuse the experiences in the design of modular fixtures with typical function structures.an automatic component modeling method on the platform of 3-D drawing software SolidWorks is proposed on the basis of assembly restriction equations.The automatic modeling principle,the method f0r building component template.the extraction of assembly parameter equations,the semantic analysis of assembly parameter equations as well as the method of assembly component dimension-driving are then analyzed.Based on these analyses,a component library system for modular fixtures is set up,and a case study is presented,thus overcoming the difficulties in automatic component modeling and providing a foundation for the automatic assembly and design of fixtures.

Key words: SolidWorks system, modular fixture, component library, automatic modeling, parameterization
