轴套零件的铣2-5mm槽夹具设计及加工工艺规程装备
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。
轴套的加工工艺规程及其铣两个宽5槽的工装夹具设计，包括零件加工的工艺设计、工序设计以及专用夹具设计三部分。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。

Abstract
The design involves the mechanical manufacturing process and machine tool fixture design, metal cutting machine tools, tolerance and measurement, and other aspects of knowledge.
The processing rules of the shaft sleeve and the design of the milling fixturewith twowidth and 5 grooves are described in this paper, including the design of the process, the design of the process and the design of the special fixture in the three parts. In the process of design should first understand the analysis of parts, parts of the process to design a blank structure, and choose the good components the processing datum, designs the process routes of the parts; then the parts of each labor step process size calculation, is the key to decide the craft equipment and the cutting process of thevarious design parameters; then a special fixture, the fixture selection for thevarious components of the design, such as connecting parts positioning elements and clamping elements, guide element, fixture and machine tool and other components; positioning error is calculatedwhen the fixture, analysis the rationality and shortcoming of fixture structure, improve and design in later.
