00总泵缸体零件图
摘要
总泵缸体工艺规程及其车Φ30端面；钻、攻M121.25-5H螺纹；钻、攻M221.5-5H螺纹；钻透孔Φ0.7、沉孔Φ3.5和Φ3.5通孔的工装夹具设计是包括零件加工的工艺设计、工序设计以及专用夹具的设计三部分。在工艺设计中要首先对零件进行分析，了解零件的工艺再设计出毛坯的结构，并选择好零件的加工基准，设计出零件的工艺路线；接着对零件各个工步的工序进行尺寸计算，关键是决定出各个工序的工艺装备及切削用量；然后进行专用夹具的设计，选择设计出夹具的各个组成部件，如定位元件、夹紧元件、引导元件、夹具体与机床的连接部件以及其它部件；计算出夹具定位时产生的定位误差，分析夹具结构的合理性与不足之处。

Abstract
Master cylinder process and car of Φ 30 end; drilling, tapping screw drill, M12 1.25-5H; attack M221.5-5H thread; drill hole 0.7, hole Phi 3.5 and phi 3.5 through holes in the fixture design process design, including the parts processing process design and fixture three. In the process of design should first of all parts for analysis, to understand the parts of the process to design blank structure, and choose the good parts machining datum, design a part of the process route; then the parts of each step of the process dimension calculation, is the key to determine the process equipment and cutting the amount of each working procedure design; then the special fixture fixture design, selection of the various components, such as the connecting part positioning element, clamping elements, guiding elements, fixture and machine tools and other components; the positioning errors calculated fixture positioning, analysis the rationality and shortcoming of the fixture structure.
