摘 要

 
本设计的课题是底座零件的机械加工工艺及夹具设计。从图纸中可以清楚的知道，底座是传动型零件的箱体，通常是被铸造成灰铸铁，它必须有很强的刚度以及强度来抵抗它的传动系统引发的振动。需要正确的解决在加工的程序里零件的定位和夹紧跟工艺路线的布置和工艺尺寸大小的确定等一系列因素，然后设计出专用的夹具来确保零件的质量。这种设计是必须要培养自主学习以及自我创新的能力。所以这种设计是全面和实用的，涵盖广泛的知识。 因此，我们不仅要关注设计中的基本概念，也需要关注生产实践。把理论和生产实践结合起来，我们才能完成好这次的设计。

ABSTRACT

The subject of graduation design is the machining process and jig design of the base part. It can be clearly seen from the drawings that the base is a box of transmission type parts and is usually cast into gray cast iron. It must have strong rigidity and strength to resist the vibration caused by its transmission system. It is necessary to correctly solve a series of factors such as the positioning of the parts and the clamping and the arrangement of the process routes and the determination of the size of the process in the processing program, and then design a dedicated jig to ensure the quality of the parts. This kind of design must have the ability to cultivate self-learning and self-innovation. So this design is comprehensive and practical, covering a wide range of knowledge. Therefore, we must not only pay attention to the basic concepts in design, but also need to pay attention to production practices. Combining theory with production practice, we can complete this design.
