【摘要】：随着工业产品更新换代周期的不断缩短,小批量生产所占的比重越来越高,适合小批量生产的高柔性组合夹具得到了越来越广泛的应用。企业在应用组合夹具的同时也提出了针对组合夹具如何更高效的设计和管理的一系列相关问题。本文针对企业的相关需求,运用CATIA二次开发方法对组合夹具的管理及设计问题进行了研究。首先研究了CATIA二次开发的相关基础知识,着重介绍了Automation API方法和CAA方法,对CAA方法的机制进行了详细的说明。比较了几种开发方法的优劣,选择了本文合适的二次开发方法。其次研究了组合夹具管理系统的建设。完成了组合夹具元件库的参数化建库工作,应用Automation API方法基于VB平台编写操作界面实现了组合夹具元件的预览和调用功能。同时编写了夹具库管理界面,实现了组合夹具元件的基本出入库管理功能。最后研究了组合夹具计算机辅助设计相关的内容,设计了工装夹具设计系统。研究了CBR方法的推理机制及其知识表达,将CBR方法应用于组合夹具快速设计中,并为工装夹具设计系统设计了XML文件输出模块。运用CAA方法在CATIA平台上实现了相应的功能。本文通过以上研究,根据需求完成了对组合夹具管理系统及工装夹具设计系统的构建,为夹具设计信息流与企业管理信息流的融合打下了良好的基础。提高了企业对组合夹具的管理及设计效率,具有较好的应用价值。
[Abstract]:With the continuous shortening of the upgrading cycle of industrial products, the proportion of small batch production is increasing, and the high flexible modular fixture suitable for small batch production has been more and more widely used. At the same time, a series of problems about how to design and manage the modular fixture more efficiently are put forward. This paper studies the management and design of modular fixture by CATIA secondary development method. Firstly, the basic knowledge of CATIA secondary development is studied, the Automation API method and CAA method are emphatically introduced, and the mechanism of CAA method is explained in detail. The advantages and disadvantages of several development methods are compared, and the suitable secondary development method is selected. Secondly, the construction of modular fixture management system is studied. The parameterized building of modular fixture component library is completed, and the previewing and calling function of modular fixture component is realized by using Automation API method based on VB platform. At the same time, the interface of fixture library management is written to realize the basic function of the modular fixture component. Finally, the related contents of CAD for modular fixture are studied, and the fixture design system is designed. The reasoning mechanism and knowledge expression of CBR method are studied. The CBR method is applied to the rapid design of modular fixture, and the output module of XML file is designed for the fixture design system. The corresponding function is realized on CATIA platform by using CAA method. In this paper, according to the requirements, the construction of modular fixture management system and fixture design system is completed, which lays a good foundation for the integration of fixture design information flow and enterprise management information flow. It improves the management and design efficiency of modular fixture, and has good application value.
