CW6163普通车床溜板箱工艺及工装设计（有CAD图纸）.pdf

___ __________ ___ _ ________ I II ABSTRACT Foundation design of body parts processing process the design of special fixture. The main processing parts processing plane and holes. In general, ensure easy to guarantee precision machining holes than. Therefore, the design principle is first machined surface after machining hole surface. Periodic hole machining plane is obvious that rough machining and machining precision machining hole. A good foundation on the bottom surface of the process. The main process is supported in the positioning hole process first, and then the processing hole plane and the hole positioning technology support. In a subsequent step, in addition to processing technology are positioned in the plane and the other hole hole and separate process. The whole process is a combination of the selection tool. Special fixture fixture selection, a self-locking mechanism, therefore, for large quantities, higher productivity, meet the design requirements. Keywords: box type parts; technology; fixture;
