Rotary indexing fixture design and assembly process planning
Abstract
　　　With the rapid development of modern computer technology, high-tech applications in modern design more and more extensive computer-aided design methods such as CAD / CAM / CAE applications in the international arena is becoming increasingly common. These design methods not only improve the design speed, and design products more reliable and beautiful, and can save a lot of manpower, material, greatly improving the competitiveness of their products. In which the actual production, rotary indexing plate is widely used, it is an important component of the force and motion passed in the machine. This article is for the rapid development of CNC machine tools, the application of computer-aided design methods to design a pneumatic wedge rotary indexing plate.
     In this design, the use of 3D CAD, as well as dynamic simulation analysis of modern design methods to establish a solid model of the rotary indexing plate to complete the structural assembly and assembly simulation, and three-jaw power rotary indexing plate working principle and design calculations were analyzed. Through the force balance equation, draw the clamping force and the push pull relationship. In the design process, the first principle of rotary indexing plate program selected according to the principles of structural design of rotary indexing plate. And mechanical analysis of the main parameters of rotary indexing plate, and the accuracy of rotary indexing plate is analyzed. Finally, according to the design of the structure of a rotary indexing plate assembly process design and simulation.
    Assembly process planning is the main content of the product assembly design, is an extremely important link in the production process, a direct impact on the final quality of the product. Rotary indexing plate design using Solidworks software, modeling and simulation to develop a structural assembly of the rotary indexing plate assembly process.

Key Words: Rotary indexing;assembly process; Solidworks
