带肩轴衬的加工工艺及铣Φ32端面夹具设计 摘要 夹具是零件加工的夹紧装置，是加工零件的一种必不可少的装置。夹具利用率高，经济性好，对功能组件的使用和数量少。随着零件的尺寸变化，越来越多的夹具被淘汰了，因此，设计一套专用夹具是十分有必要的。在设计专用夹具时要考虑工件的定位方案，工件的夹紧方案和设计夹紧机构，夹具的其他组成部分，夹具的结构形式等。 本次设计的题目是带肩轴衬的加工工艺及铣Φ32端面夹具设计，根据老师给的图纸要求进行工艺设计和夹具设计，在掌握零件作用的基础上，对零件的工艺进行分析。针对设计给定的题目，设计里面主要对机床夹具进行设计。本夹具体是以保证加工精度，生产效率和便于工人操作为宗旨展开的设计。 设计之初我查阅相关数据及国内外关于机床夹具的文献，在看懂零件图的同时对零件的结构和工艺进行分析，明确粗基准和精基准的选择，确定零件的加工余量与毛坯的尺寸、从而确定零件的加工工艺过程、计算各工序的切削用量及工时。最终完成了本次设计所需的夹具。 关键词：带肩轴衬；加工工艺； 铣Φ32端面；夹具设计  Abstract Jig is the clamping device for parts processing, which is an essential device for processing parts. The fixture has the advantages of high utilization rate, good economy, and less use and quantity of functional components. With the change of the size of parts, more and more fixtures are eliminated. Therefore, it is necessary to design a set of special fixtures. When designing the special fixture, we should consider the positioning scheme of the workpiece, the clamping scheme of the workpiece and the design of the clamping mechanism, other parts of the fixture, the structure of the fixture and so on. The subject of this design is the processing technology with shoulder shaft lining and the design of milling_32 end-face fixture. According to the drawings given by the teacher, the process design and fixture design are carried out. On the basis of mastering the role of the parts, the process of the parts is analyzed. For the design of a given topic, the design mainly focuses on the design of machine tool jig. The clip is specifically designed to ensure machining accuracy, production efficiency and ease of worker operation. At the beginning of the design, I consulted the relevant data and the domestic and foreign literature about the machine tool fixture, analyzed the structure and process of the part while reading the part drawing, made clear the choice of the rough datum and the precision datum, determined the machining allowance of the part and the size of the blank, thus determined the processing process of
