钻18孔夹具装配图
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。
张紧轮支架加工工艺规程及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 thevarious knowledge.
The reduction gear box body components technological process and its the processing hole jig design is includes the components processing the technological design, theworking procedure design aswell 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 ofworking procedure, the key is decides eachworking 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 the part, to clamp concrete and the engine bed connection part aswell as other parts; Position errorwhich calculates the jig locateswhen produces, analyzes the jig structure the rationality and the deficiency, andwill design in later pays attention to the improvement.
Keywords: The craft, theworking procedure, the cutting specifications, clamp, the localization, the error
