摘要本文介绍了一种计算机辅助模块化夹具配置设计系统FIX-DES。当夹具要求指定为定位/夹紧面和点时，由1自动生成夹具配置。根据夹具元件的装配关系，从夹具元件数据库中选择夹具元件形成夹具单元。在保持夹具要求和装配关系（如孔对齐）的情况下，将夹具单元和元件放置在底板上。当确定夹具元件的几何模型和夹具功能时，可以自动建立夹具元件的装配关系，从而使FIX-DES系统能够方便地应用于不同的夹具系统。系统还提供了人机交互设计和设计修改功能，便于专家参与。该系统采用C和c++语言编写核心程序，并在特定的CAD环境下编写接口程序。该系统已成功地应用于工业中，可方便地移植到其他CAD系统中。本文介绍了FIX-DES系统的总体结构。详细介绍了自动夹具配置设计（AFCD）功能的开发。最后给出了夹具结构设计实例，说明了该系统的应用。
AbstractThis paper presents a computer-aided modular fixture configuration design system: FIX-DES. When fixturing requirements are specified as locating/clamping surfaces and points, a fixture configuration will be automatically generated by1.Selecting fixture elements from a fixture element database to form fixture units based on fixture element assembly relationships.2.Placing the fixture units and elements into position on a baseplate while the fixturing requirements and assembly relationships (e.g. hole alignments) are maintained. The fixture element assembly relationships can be established automatically when the geometric models and fixturing functions of the fixture elements are specified so that the FIX-DES system can be applied easily to different fixture systems. The system also provides the interactive design and design modification functions for human expert involvement. The system was developed with core programs in C and C++ and interface programs in a specific CAD environment. The system has been successfully applied in industry and can be transferred easily to other CAD systems. The overall structure of the FIX-DES system is introduced in the paper. The development of the automated fixture configuration design (AFCD) functions are presented in detail. Finally a fixture configuration design example is given to illustrate the application of the system.
