摘 要

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。
走刀拨重器加工工艺规程及其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，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。

This design content has involved the machine manufacture craft and
the engine bed jig design, the metal-cutting machine tool, the common
difference coordination and the survey and so on the various knowledge.
The reduction gear box body components technological process and its
the processing hole jig design is includes the components processing the
technological design, the working procedure design as well as the unit
clamp design three parts. Must first carry on the analysis in the
technological design to the components, understood the components the
craft redesigns the semi finished materials the structure, and chooses the
good components the processing datum, designs the components the craft
route; After that is carrying on the size computation to a components each
labor step of working procedure, the key is decides each working procedure
the craft equipment and the cutting specifications; Then carries on the unit
clamp the design, the choice designs the jig each composition part, like
locates the part, clamps the part, guides th
