Abstract:Based on the premise of unified process datum, a set of modular fixture system of zero point positioning is designed so that it can quickly complete the precise positioning and clamping of the workpiece. In view of the practical application of the modular fixture system of zero point positioning, the parameterized modeling of key parts of the fixture system is completed based on the basic principle of the secondary development of NX software. The main research work includes: the design of the dialog box, the writing of the application program and the writing of the script file of the menu. Through the research on the parameterized design of the modular fixture system of zero point positioning, the fixture system can be adjusted and assembled quickly according to the basic conditions of production, greatly improving the working efficiency of CNC machine tools and laying a foundation for the automatic production of the products.
Key words:modular fixture system of zero point positioning;secondary development;parametric design
