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。
端盖的加工工艺规程及其宽8槽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；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：切削用量、夹紧、定位、误差。

ABSTRCT

The design of the content relates to the machinery manufacturing technology and machine tool

fixture design, metal cutting machine tool, tolerance and measuring and other aspects of

knowledge.
End cover processing procedure and 8 wide groove of fixture design is including machining

process design, process design and fixture design in three parts. In the design process

should first of all parts for analysis, to understand the parts of the process to design a

rough structure, and choose the good parts processing base, design parts of the process

route; and then the various parts of the process step size calculation, is the key to decide

the process equipment and cutting parameters; then special fixture design, selection and

design of a jig for the various components, such as positioning devices, clamping elements, a

guide element, clamp and the machine tool connecting parts and other components; calculate

fixture is produced when the positioning error analysis, fixture structure rationality and

deficiency, and later in the design of improved.
Key words : cutting, clamping, positioning, error.
