General component is common machine tool fixture positioning device, clamping device, connecting element, element, lead the knife or other components and concrete and so on several parts, the structure is relatively complex, for lack of practical knowledge students, teaching material and teacher lectures alone still understand thoroughly, in order to solve this problem, the school bought a typical machine tool fixture AIDS, used in classroom teaching and experimental teaching. To improve supporting information, to improve the application effect of AIDS and experimental efficiency, put forward this topic. We in AIDS milling clamp, lathe, drilling jig for the several types of machine tool fixture remove the former record, disassembly, measurement, UG drawings, such as work, and then using UG software to complete the virtual modeling, virtual assembly animation function of the assembly fixture can be the assembly sequence with an animated demo out components. The main content of this subject is divided into four parts. First is the design principle of machine tool fixture, and through the first chapter of learning we can learn about the components and functions of the fixture, grasp the workpiece in the fixture positioning, understand the typical machine tool fixture, master the basic classification of existing fixture, understand the typical fixture clamping mechanism, these are the basis of the design, analysis and reasonable selection of machine tool fixture. Then is mentioned in the second chapter about this topic research under the school of machine tool fixture and some of the preparation and analysis of process and assembly, including machine tool fixture ready to tear open outfit, measure often used by workers gauge, machine tool fixture AIDS preparation method and the matters needing attention in assembling and disassembling, recording work steps, equipment, measurement equipment, removal of equipment assembly, machine tool assembly process analysis. Then there is the introduction of UG software, and through the study we learn in chapter 3 of the UG software introduction, features, advantages compared to other 3 d modeling software, as well as the application process under this topic, more intuitive to learn UG software assembly animation production process. The last in the fourth chapter is about the application of UG software, which is under this topic retained by using UG software to complete the task of the specific steps, in this topic more intuitive understanding of the process and the function of UG software applications. Above is the direction of this topic research and the work, through this topic research and the results can clearly express the assembly relation of each parts, for lack of practical knowledge of the students can visualize fixture parts, each part of the perfected the teaching materials, offer great help to the teaching in the fixture.Key Words：Drilling Fixture Structure principle Assembly process UG Assembly animation第一章 机床夹具简介本章介绍了机床的夹具，重要就夹具的概念、组成、几种典型机床的夹具、各部件的功能和作用以及本文的几种夹具进行了简朴的阐述。通过对本章的了解可以达成对夹具的基本知识的掌握，这些是设计、分析、和合理选用机床夹具的基础
