副翼摇臂A3
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。
副翼摇臂的工艺规程及其钻2-Φ8H8孔的工装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。

Abstract
The design content of the mechanical manufacturing technology and machine tool fixture design, metal cutting machine tool, tolerance matching and measurement of aspects of knowledge.
Rocker flap procedure and its 2-Φ8h8holes of fixture design is including parts processing process design, process design and special fixture design three parts. Should first analyze the parts in the process design, understand parts of technology to design the structure of blank, and choose the good parts processing benchmark, design process of the parts; Then the parts size of eachwork step of the process, the key is to determine the process equipment for each process and cutting parameter; For the design of special fixture, then select design out of the component parts of the fixture, such as the positioning device, clamping device, led components, specific connectionwith machine parts and other parts; Calculated at the exit of fixture locating position error, analysis the rationality of the fixture structure and deficiency, and pay attention to the improvement in the later design.
Keywords : Aileron rocker arm, fixture design, process route.
