弯臂杠杆二的铣宽10槽R65圆弧面夹具设计及加工工艺装备含非标5张CAD图

铣槽夹具装配图

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。
杠杆加工工艺及铣R65槽，宽10mm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：杠杆、工艺规程、切削用量、夹具设计

Abstract
This design involves many aspects of knowledge, such as mechanical manufacturing process, machine tool fixture design, metal cutting machine tool, tolerance matching and measurement.
The lever processing technology and the fixture design of milling R65 groove with a width of 10mm include the process design, process design and special fixture design of part processing. In the process design, we should first analyze the parts, understand the process of the parts, then design the structure of the blank, select the processing benchmark of the parts, and design the process route of the parts; Then calculate the size of each process step of the part, and the key is to determine the process equipment and cutting parameters of each process; Then the special fixture is designed, and each component of the fixture is selected and designed, such as positioning element, clamping element, guiding element, connecting part between the clamp and the machine tool and other parts; Calculate the positioning error caused by fixture positioning, analyze the rationality and shortcomings of fixture structure, and pay attention to improvement in future design.
Key words: lever, fixture design, process
