阀体零件带分度装置的车床夹具设计（有CAD图纸）.pdf

I II Fixture design basis for the design of the design of the cylinder parts machining process. The main processing site is flat and hole machining. In general, to ensure that it is easy to ensure the precision machining than the hole. Therefore, the design principle to follow is processed after the first hole surface machined surface. In parts of the fixture design, parts machining process is mainly based on the requirements analysis should be limited to the number of degrees of freedom, and then depending on the surface characteristics of the selected parts of the positioning element, and then analyze whether the limit should be selected positioning element limit freedom. After determining the positioning elements also need to select the clamping element, is to determine the final form of the structure of special fixture.
