偏心轴
摘要
此次课程设计包括了偏心轴零件工艺过程的设计和专用夹具设计两个部分，因为此前没有设计夹具的经验我在设计之前在网上查阅了相关资料并参考和借鉴其中的一些经验以此改进我的设计。
此次设计研究的目的就是为了更好的掌握机械制造的大致流程以及具体的设计方法，我的设计方法是因考虑到自己经验不足所以参考专业书籍根据自己的题目加以改进从中汲取经验。我的设计结果满足了夹具定位基本原理和重要计算结果的验证。结论是在设计偏心轴机械加工工艺过程时要通过查表法准确的确定各表面的总余量及余量公差，合理选择机床加工设备以及相应的加工刀具，进给量，切削速度、功率，扭矩等用来提高加工精度，保证其加工质量。根据零件加工要求制定出可行的工艺路线和根据夹具定位误差是否合理选择夹具方案，以确保零件的加工质量。
Abstract
This course design includes two parts: the design of eccentric shaft parts process and the design of special fixture. Because there is no previous design experience, I consulted relevant information online before the design and referred to some of the experience to improve my design.
The purpose of this design study is to better grasp the general process of mechanical manufacturing and specific design methods, my design method is to take into account their lack of experience, so reference professional books according to their own topics to improve and learn from experience. My design results meet the basic principle of fixture positioning and the verification of important calculation results. The conclusion is that when designing the machining process of eccentric shaft, the total allowance and allowance tolerance of each surface should be accurately determined by looking-up table method, and the processing equipment and corresponding cutting tools, feed, cutting speed, power and torque should be reasonably selected to improve the machining accuracy and ensure the processing quality. According to the requirement of parts processing, the feasible technological route and reasonable fixture scheme are worked out to ensure the quality of parts processing.
