组合夹具结构设计自动化系统研究

RESEARCH ON THE SYSTEM OF MODULAR FIXTURE DESIGN AUTOMATION

在广义映射原理指导下，开发了支持“ｔｏｐ－ｄｏｗｎ”风范的组合夹具设计自动化软件系统。在对零件夹持特性分析基础上，提取夹具需求信息，建立了组合夹具的功能要求集合，并对组合夹具功－构映射关系进行了全面分析，对组合夹具概念结构实施多方案重构，并进行了实例验证。为夹具结构设计自动化软件系统的开发探索出一条新的途径。

The theories and application of modular fixture design automation are investigated. Under the guidance of the theory of generalized mapping, a' top - down' fixture design automation software is developed. On the analysis of the fixturing characteristics of workpiece, the design requirement is extracted. The process of function - form mapping relationship is researched, whereby the conceptual fixture structure is deduced. The muti - schemetic reconstitution of the conceptual fixture structure is realized. And the theory and methodology is lastly exemplified, where a new approach of fixture design automation is explored.
