机床专用夹具参数化虚拟装配技术研究
|
摘要
机床夹具在机械加工中起着重要的作用,它直接影响着机械加工的质量,生产效率和成本。机床夹具设计效率和设计质量对产品的上市时间和质量的影响越来越大,同时企业在长期的机床夹具设计过程中积累了丰富的设计经验,迫切需要一种高效可行的方法来重复利用这些已有的设计经验以提高机床夹具设计的质量和效率。
本文针对这一企业需求,对基于CAD软件Pro/E的机床夹具快速设计理论和系统的开发方法进行了研究,对机床夹具零件库的自动建模原理和关键技术进行了详细的研究,并在此基础上,采用了基于约束方程的机床夹具部件自动建模方法,创建了机床夹具零件和部件信息模型,实现了机床专用夹具零件和部件的柔性建库。建立了统一的机床专用夹具对象装配模型,采用了基于典型实例的机床专用夹具设计方法,重点研究了机床专用夹具检索模型、实例组织模型、实例修改推理机制和实例存储策略。研究了基于Pro/E的机床专用夹具快速装配方法,实现了机床专用夹具快速装配。
Machine tool fixture is very important equipment in process machine manufacturing process because it influences the production quality, efficiency and cost directly. Thus, the efficiency and quality of machine tool fixture design plays a more and more important role in improving product quality and shortening its time coming into market. Meanwhile, manufacturing corporations have accumulated abundant fixture design experiences in practice, and an available and effective method is needed urgently to be established by using the valuable knowledge in order to improve machine tool fixture designing level.
In order to satisfy this requirement, machine tool fixture virtual assembly design theory and system development methods, based on CAD software: Pro/E, are studied. This dissertation studies deeply the theory and key techniques of machine tool fixture element automatic modeling based on Pro/E. Based on this, machine tool fixture component automatic modeling method is developed, which is depended on assembly restriction equations. Machine tool fixture element and component information model is proposed. Thus, machine tool fixture element and component library is carried out, which orients machine tool fixture rapid design is extensible. Machine tool fixture object assembly model is established, machine tool fixture design theory and realization based on typical instance is proposed. Machine tool fixture searching model, instance organization model, instance modification and reasoning mechanism and instance storage tactics are studied in detail. Computer aided machine tool fixture rapid design system (CAMFRDS) based on Pro/E is developed, and a case study is presented.
