Study good its axial parts fixture design, can improve and develop more advanced deceleration device, also can be a very good advance production efficiency and create greater efficiency. However ,machine is the design of special jig working content of the important process of preparation. The quality of the special fixture design machine tools, directly affects the accuracy of workpiece, quality, productivity and processing cost, sometimes even determines whether the design of fixture use value. In the production practice, due to some factors to consider different, design and manufacture of fixture cant use out has appeared. Examples Therefore, only making full use of the basic principle and fixture design knowledge, correctly grasp the basic methods of fixture design. To design advanced and reasonable and practical machine special jig. Special fixture design must make machining quality, productivity, labor conditions and economic aspects of the dialectical unity to. Which is the most basic guarantee the machining quality requirements. In order to increase productivity adopts advanced structure and mechanical transmission device, often can increase the manufacturing cost, but fixture the batch when the workpiece is increased to certain scale, obtained by the piece man-hour drop econom
