Secondarydevelopment technology of parameterized design for modular fixture based on SolidWorks

Objective—To solve the problem of complex modeling process and long modification period and to realize quick design of modular fixture by developing standard component library of modular fixture based on VC software,which was connected with SolidWorks 3D software completely,and by designing human conversation interface.Methods—Based on the platform of 3Dsoftware SolidWorks,specific software module which can meet the need of the users was developed by using dimension driving method,utilizing API provided by 3Dsoftware to invoke the functions of the software.Results—3D standard components library of parameterized modular fixture was built,and parameters can be input according to the requirement of the users.The existed 3D model was driven to realize parameterized modeling,quick design and optimization of the fixture and virtual assembly.Conclusion—The experiments show that secondary development of modular fixture based on SolidWorks can make the commands repeatedly called once the model is built.The proposed method provides research platform for modular fixture design and virtual assembly.
