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。
接入耳环的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。
Abstract
This design involves the mechanical manufacturing process and machine tool fixture design, metal cutting machine tools, tolerance and measurement, and other aspects of knowledge.
The technical specification and fixture design for the access to the earrings are three parts, including process design, process design and special fixture design. 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 the various design parameters; then a special fixture, the fixture selection for the various 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 calculated when the fixture, analysis the rationality and shortcoming of fixture structure, improve and design in later.
Key words: process, process, cutting parameters, clamping, positioning, error.
