Study Of Fixture 3D Standard Part Library

The development of manufacturing informatization impels many corporation establishing corresponding computer aided design andmanufacture(CAD/CAM)software condition,and evident effect is achieved by applying the CAD/CAM software to design,analyze,process,simulate and manufacture the product.using CAD/CAM software to complete the process of machine tool fixture design is a way of speeding up the efficiency of fixture design and improving design quality.but the existing general CAD/CAM software has no integrity technology data software aim at machine tool fixture design.therefore,it affect the efficiency and the quality of mold design that designers stil query the datum,choose parameter,and mark a copy of the results through the traditional paper tools,and manually choose and input technology parameter.thereby,studying on digitization design for machine fixture and 3D standard library is important to meet the demand of engineering technician in digitization times. according to serious analysis and summary of datum of national machine fixture design,and applying modem CAD,database and computer network technology,we put up works on developing 3D standard library.Through investigating, comparing, analyzing the variable CAD software and thinking about the degree of difficulty, transportability and maintainability, the 3D CAD software SolidWorks was selected as the developing platform and Visual Basic program technique and database management technique of Access was utilized. By the secondary development function of SolidWorks API, a feature-based and parameter-driven parts library for machine tool fixture developed. After developing the other parts library system can be perfected,and then it will have a good application future in designing and manufacturing of tool fixture for the enterprises which lake technical personnel.
