Sichuan Vocational and Technical College 2012.09—2013.04 1 . 2 Abstract The process of connecting parts processing application and processing analysis, mainly includes the selection of the parts diagram analysis, the semifinished materials, parts of the clamping, the process route of making, tool selection, cutting the amount of determination, the process file to fill. Choose the correct processing method, design reasonable processing technology. In addition to the packing box cover parts of the two process design of the special fixture. There are many types of machine tools, including the use of the most widely used universal fixture, standard size has been standardized, and a professional factory for production. And it is widely used in mass production, and it is a special fixture for the service of a particular workpiece. The main content of this paper is the design of boring fixture fixture design.
