六角螺栓车总长装置设计
摘    要
 
本课题是针对某厂生产的零件（六角螺栓）进行车总长的装置设计，该课题是对某企业实际产品的加工过程设计，具有较强的实践性，需实习调研过程。在我们去实践观察的过程中不仅提高了自身的观察能力而且也同时提高了我们的思考，判断等综合能力。通过对该课题的研究和设计，可以巩固我们对所学理论知识掌握，提高我们解决实际生产中设计开发问题的能力和创新性。在我的毕业设计中，综合各方面的考虑自己设计了一个弹簧夹头，其中弹簧夹头的材料是很有讲究的，这在后面都会说到。夹头主要利用了楔形结构。因为工厂的工作环境和成本效率，我选择了气动的传动方案。虽然看上去很简单，但是就生产效率的提高上去看绝对起到了非常大的效果。

The lathing total length fixture design of tapped stud
Abstract
This topic is for a certain part(hex bolts) which should be turn the total length out. The subject is very practical.It also need to investigate in the factory.During the investigation,it do not only promote our ability of observation but also enhance our thinking and judgment comprehensive abilities.We can turn our theoretical knowledge into practice.In my graduation design,I have considered many aspects.I  have designed  a spring chuck which is wedge-shaped.The material of the spring chuck is complex.Because of the working environment and the cost,I think the pneumatic transmission is best.Although it is easy,it is very useful for the improvement of the efficiency.
