变速器换挡叉夹具设计说明书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 ￠ 140 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 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
