Abstract

Determined by the process route of shell parts, the parts processing to the bottom as the benchmark is appropriate, the processing technology solutions to meet the four basic requirements of the principle of coarse and fine reference datum. The fixture is a special clamp, and the fixture is characterized by strong pertinence, compact structure, simple operation and high productivity. In this design, fixture design and meet the basic requirements of overall design of the fixture, and fully guarantee the quality of machining and has high production efficiency and low manufacturing cost and good structure technology. The main content of this graduation project is the design of the machining process regulations and the design of the special jig for drilling the 12 steps hole on the left side. The basic theory and method of comprehensive use of machinery manufacturing technology and other courses, in order to design tasks can be completed fixture shell parts machining technology and drilling, the integrated use of knowledge and apply the correct design method, the machining process planning for shell parts. With the content of process design, calculation method of skilled application process, the process of content analysis and design calculation of the right, such as cutting force, cutting power, cutting speed, process parameters, positioning error the clamping force and so on.

Key words: machining; process specification; special clamp shell
