This design is the flange is a CA6140 lathe horizontal flange, which is located lathe screw at the end, the main role is to indicate scale, to achieve vertical feed. First, we must familiarize themselves with spare parts, to understand the role of flange , the next according to the nature of components and parts diagram of the roughness on each face to determine the size and mechanical rough machining allowance. Then we re-positioning the benchmark according to first determine the precise benchmarks determined rough benchmark, the finalization process flange road map for developing the workpiece clamping program, draw fixture assembly diagram. 目录 1、法兰盘的工艺分析及生产类型的确定 1 1.1 法兰盘的用途………………………………………………………… 1 1.2法兰盘的技术要求………………………………………………….. 2 1.3法兰盘的生产类型………………………………………………………3 2.确定毛坯绘制毛坯简图…………………………………………………..4 2.1选择毛胚………………………………………………………….4 2.2确定毛胚的尺寸公差和机械加工余量…………………………… 5 2.2.1公差等级…………………………………………………….6 2.2.2法兰盘铸造毛坯尺寸工差及加工余量…………………
