The purpose of this project is generally milling cutter head base mechanical manufacturing process and fixture design. In the first part of the manufacturing process design, the main work is casting of milling cutter head base , machining and line set, mechanical inspection and calculation process, the preparation of the main process documents. The Fixture Block of milling cutter head base is an important part of this project and also is a part of this difficult subject, mainly milling fixture design is clamping and positioning. these will affect the processing of the dimensional accuracy and position accuracy of ponents. The issue is used three holes of the positioning inone surface . the positioning of such a general way the fixture structure is relatively simple and has good positioning stability. Clamping institutions are mainly spiral , position of this structure is relatively simple, self-locking performance, high reliability. drawing three-dimensional and assembly drawings. Key words : milling machine; milling cutter head base; manufacturing processes;fixture design 购买文档送 CAD 电子版图纸, Q 11970985 或 401339828 V 目录摘要............................................................................................................................ ....................
