1、设计说明书题目输出轴的加工工艺及车左端及外圆面夹具设计班 级:姓 名:指导教师:完成日期:本次设计内容涉及了机械制造工艺及机床夹具设计、金属切削机床、公差配合与测量等多方面的知识。输出轴零件的工艺规程及车左端及外圆面的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
2、;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,并在以后设计中注意改进。关键词:工艺、工序、切削用量、夹紧、定位、误差。ABSTRCTThis design content has involved the machine manufacture craft and theengine bed jig design, the metal-cutting machine tool, the common differencecoordination and the survey and so on the various knowledge.The reduction gear
