摘　　要：分析了当前的一些 CAD软件平台标准件建库的方法 ,研究了夹具的常用对象的构成及其信息特点 ,创建了底层的种子件 ,形成种子组件和典型种子结构 ,以动态建库的方法 ,生成参数化的哑图、属性信息和尺寸数据的常用件库、常用组件库以及典型结构库 ;通过建库工具进行动态添加 ,并形成调用、编辑相分离 ,以及采用离线编辑的功能 ,使所创建的常用库具有开放、可扩充、易维护与安全的优点 ,实现了常用对象的设计重用 。Analyzing the methods of setting up standard parts library in current CAD systems, studying the constitution and information feature of the common-objects, it is established the common-use library which include the common-use component library, common-use components library and typical structure fixture library in the paper. And the seed component in the bottom layer forms the seed components and typical seed case, which has the 3D parametric geometric model, attribute information and dimension data. By building library tool, the common-objects can be added easily to the library. And mechanism is formed to separate with reuse, modification, to have the function that modifies the objects in non-line. Therefore the common-use library have the advantage of opening, expandable, easily maintain and security, and realize the common-objects for design reuse, also improve the efficiency of the fixture design.
