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。
三孔连杆加工工艺规程及钻Φ35H6孔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, mon difference coordination and the survey and so on the various knowledge.
Three-hole processing technology of connecting rods and its the processing Φ 35H6 drill hole of jig design is includes ponents 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 ponents, understood ponents the craft redesigns the semi finished materials the structure, and chooses the ponents the processing datum, designs ponents the craft route; After that is carrying on the putation to ponents 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 position part, like locates the part, clamps the part, guides the part, to clamp concrete and the engine bed connection part as well as other parts; Position error which calculates the jig locates when produces, analyzes the jig structure the rationality and the deficiency, and will design in later pays attention to the improvement.
Keywords: The craft, the working procedure, the cutting specifications, clamp, the localization, the error
