Study on the Fixture Analysis and Configuration Method for Computer-aided Modular Fixture Design

Abstract

Modular fixture design is a complex process. Computer-aided modular fixture design can help to accumulate the experience and technology of fixture designer. In this paper, the optimal configuration method of hole modular fixture is studied in computer-aided modular fixture design. Firstly, the characteristics of the modular fixture is analyzed, with the detail information needed during the fixture design process given, including the structure information, function information and assembly feature information of the element. Fixture information description model is built to support the database design of the modular fixture and the automatical generation of the modular fixture. An optimized configuration algorithm is studied to generate the modular fixture from the fixture elements to meet the requirements. Finally, an illustration is provided to testify the feasibility the algorithm. Keywords-modular fixture; optimal configuration; fixture analysis
