Abstract

Through the determination of the processing route of the shell part, the processing of the part is suitable as the reference. The processing plan satisfies the basic requirements of the rough reference selection and the four principles of the fine reference selection. The fixture is a special fixture, the fixture is characterized by strong, compact structure, easy operation, high productivity. In this design, the design of the fixture to meet the overall requirements of the overall design of machine tool fixture, and fully guarantee the quality of parts processing, with high production efficiency and lower manufacturing costs and has a good structural process. The main content of this graduation design is the preparation of mechanical processing procedures and two procedures for fixture design. In order to be able to complete the machining process of shell parts and the design task of drilling machine and milling machine fixture, we should use the knowledge of the method and apply the correct design method, and formulate the shell. The basic theory and method of mechanical manufacturing technology and other courses are used synthetically. Part of the mechanical processing procedures. Combined with the process design content, skilled application of process calculation method, the relevant process content of the correct analysis and design and calculation, such as cutting force, cutting power, cutting speed, process parameters, positioning error, clamping force.
