凸轮轴零件图A3
摘要
凸轮轴是汽车上非常重要的零件之一，位置位于汽车的发动机。该零件的作用是调节以及控制气门的闭合，开启及其调节启闭的工作角度等等。为汽车的正常工作提供保障。凸轮轴是比较典型的轴类零件，轴类零件应用非常广泛，从而对凸轮轴进行研究非常有必要。
这次设计的内容主要有凸轮轴加工工艺规程的设计和凸轮轴专用夹具的设计。在一开始对其进行设计的时候，主要研究的凸轮的作用，材料的选择，加工工艺路线的制定还有零件在加工的时候其切削用量的选择等等。
通过商定决定设计磨IV段凸轮磨床专用夹具设计。在对其进行设计之前，对磨床的组成、加工范围等知识点进行掌握；依据零件的结构特点设计了定位方案和夹紧方案并选择了相应的元件。对夹具体进行设计，画出装配图以及零件图等。

Abstract
The camshaft is one of the most important parts of the car and is located in the engine of the car. The function of the part is to adjust and control the closing of thevalve, opening and adjusting theworking angle of the opening and closing, and the like. Provide protection for the normalwork of the car. Camshafts are typical shaft parts, and shaft parts arewidely used, so it is necessary to study camshafts.
The design of this design mainly includes the design of the camshaft machining process specification and the design of the camshaft special fixture. At the beginning of the design, the main research of the role of the cam, the choice of materials, the development of the processing route and the selection of the cutting amount of the parts during processing.
The design of the special fixture for the grinding IV segment cam grinderwas decided by agreement. Before designing it, master the knowledge points of the composition and processing range of the grinding machine; design the positioning scheme and clamping scheme according to the structural characteristics of the parts and select the corresponding components. Design the clip specifically, draw the assembly drawing and the part drawing.
Keywords: camshaft, process specification, special fixture, IV segment cam, grinder
