4、将夹具的各零部件装配顺序用动画演示出来。本课题的主要内容分为四个部分。首先是机床夹具的设计原理，通过对第一章的学习我们能够了解到夹具的组成和功能，掌握工件在夹具中的定位，了解典型的机床夹具，掌握现有夹具的基本分类，了解夹具典型的夹紧机构，这些都是设计、分析和合理选用机床夹具的基础。然后是第二章中提到的关于本课题下研究的学校机床夹具教具的一些准备工作及工艺和装配分析，包括机床夹具拆装、测量中常使用的工量具的准备、机床夹具教具的拆前准备、拆装方法和注意事项、记录工作步骤、设备的拆卸、设备的测量、设备的装配、机床装配工艺分析。接着就是UG软件的介绍，通过对第三章的学习我们可以了解到UG软件的简介、特
5、点、相比较其他三维造型软件的优势、以及在本课题下的应用过程，较为直观的学习UG软件的装配动画的制作过程。最后是第四章中关于UG软件的应用，也就是在本课题下利用UG软件完成所留任务的具体步骤，更为直观的了解在本课题下就UG软件应用的过程和所用的功能。以上就是本课题研究的方向及所做的工作，通过本课题的研究及所做成果可以清晰表达出各零件的装配关系，对于缺乏实践知识的学生们可以直观查看夹具的各部分零部件，完善了教学资料，为夹具的教学提供很大帮助。关键词：钻床夹具 结构原理 装配工艺 UG 装配动画IAbstractMachine tool fixture is an important part of
