【摘要】：针对齿轮泵装配工艺规划中三维建模与装配工艺信息素脱节,且二维计算机辅助装配工艺过程设计不能动态反映零部件装配工艺过程与干涉性等问题,提出了一种基于3DCAPP-A的装配工艺优化方法。通过对齿轮泵三维建模分析和装配信息素提取,完成3DCAPP-A与UG集成系统创建;其次在3DCAPP-A环境中对齿轮泵装配信息素进行完善添加,建立三维装配工艺知识库,为装配工艺专家系统设计提供知识来源;最后利用UG二次开发工具,对装配工艺专家系统进行开发技术研究。结合实例表明,运用专家系统和UG集成开发技术,可以实现装配工艺信息素的流动,并能动态反映零部件装配工艺过程与干涉性等问题;减少二维视角带给技术人员的模糊装配设计,从而降低生产成本,提高效率。
[Abstract]:Aiming at the problems of 3D modeling and disjointing of assembly process information element in gear pump assembly process planning, and 2D computer aided assembly process design can not dynamically reflect the assembly process and interference of parts and components, etc. An assembly process optimization method based on 3DCAPP-A is proposed. Through 3D modeling analysis and assembly pheromone extraction of gear pump, the integrated system of 3DCAPP-A and UG is established. Secondly, the assembly pheromone of gear pump is added in 3DCAPP-A environment, and the 3D assembly process knowledge base is established. It provides knowledge source for the design of assembly process expert system, and finally studies the development technology of assembly process expert system by using UG secondary development tool. The application of expert system and UG integrated development technology can realize the flow of assembly process pheromone, and can dynamically reflect the problems of assembly process and interference of parts. It reduces the fuzzy assembly design brought to technicians by two-dimensional visual angle, thus reduces the production cost and improves the efficiency.
