1、 i 基于 UG 的万向节滑动叉零件的 工艺规程及工装设计 摘 要 万向节滑动叉主要用于在两个不同的心轴或有一定夹角的轴间传递动力， 使用万 向节滑动叉可以简化万向传动装置的结构， 因此对于万向节滑动叉的研究具有深远的 意义。 本次设计的主要内容就是制订万向节滑动叉的相关工艺规程， 并设计其中的两套 专用夹具，运用 UG 软件建立实体图并导出装配动画和爆炸图，导出二维图并应用 CAD 修改。设计内容需要运用各方面的机械专业知识，是对我们学习成果的全面考 察也是对专业软件应用熟练程度的一次考验，UG 和 CAD 等专业软件的运用大大提 高了设计者的工作效率，省去了手工绘图的麻烦，给设计过程带来了
2、极大地方便。 总的来说本次设计是对四年专业知识学习的总结与提高，是一种知识层次的升 华。 关键词：万向节，滑动叉，工艺，专用夹具 ii The Process Procedures and Tooling Design of Universal Joint Sliding Fork Based on UG Abstract Universal joint sliding fork is located in the top of the transmission shaft. The main use of it is transferring power between the two di
3、fferent heart shaft or the shaft that is having certain angle. The use of universal joint sliding fork may simplify the structure of universal transmission device, so it is important to make a research of it. The main purpose of research is improving the processing efficiency by making some process
4、procedures. Due to the complexity of its structure, it needs the assistant of special jig during the processing process. So we need to design two special jigs that is used during the processing process. In the process of designing, we need to use some professional drawing software, such as UG or CAD
5、. So the graduation design is not only the test for our professional knowledge, but also the investigation for our use of some software. Through the professional knowledge work out relevant process planning and design related fixture. Then we need to draw the fixture assembly drawings and explosion
6、figure with UG, and using CAD modify 2d figure. Generally, the graduation design is an actual combat maneuvers for our abilities. It is important for us about the development of our future.
