This is what we doing right by the school prior to graduation each course an in-depth and comprehensive review of the total, also a theory of practical training. Therefore, it has an important position in our four years of university studies. The design task is the cover, There are parts map, blank map, clip specific diagrams, assembly drawings. Machining process with the design of fixture cards and working procedure of the process corresponding to that card. First, we must familiarize themselves with spare parts, Given topic is the cover . Understanding of the role of cover, Next, according to the nature of components and parts diagram on each face to determine the roughness of rough size and mechanical machining allowance. Then we re-positioning the benchmark according to first determine the precise benchmarks determined rough benchmark, the finalization of the road map process cover. Enactment of the workpiece clamping program, draw fixture assembly diagram. 目录 1、端盖的工艺分析及生产类型的确定 1 1.1、端盖的用途 1 1.2、端盖的技术要求 1 1.3、审查端盖的工艺性 2 1.4、确定端盖的生产类型 2 2、确定毛胚、绘制毛胚简图 3 2.1选择毛胚 3 2.2确定毛胚的尺寸公差和机械加工余量 3 2.2.1公差等级 3 2.2.2端盖铸造毛坯尺寸工差及加工余量 3 2.2.3绘制端盖毛坯简图 4 3、拟定端盖工艺路线 4 3.1、定位基准的选择 4 3.1.1．精基准的选择 4 3.2.2
