Study of Computer-Aided Design Process and Methods Based on Welding Fixture

Although various computer-aided fixture design (CAFD) systems have been developed to assist the designer during the various stages of fixture design, most of previous computer aided fixture design research has mainly concentrated on machining fixtures rather than welding fixtures. The development of complicated computer aided welding fixture design (CAWFD) system has received much less attention. Welding fixture can ensure welding dimension, improve assembly precision and efficiency. It can prevent the welding deformation. The function of welding fixture was introduced in this paper. The computeraided welding fixture design workflow was developed. The design steps include the project creation, setup design, Orientation and position determination, fixture plan design, fixture configuration design, fixture design verification and fixture design output. The classification of welding fixture component has been demonstrated. Information tree and the database tables to save the unit information are designed. The unit information retrieval menu and interface based on UG, Visual C++ and database is realized.
