【摘要】：近年来,随着制造业的快速发展,非标设备越来越广泛应用在机械装备中,给非标企业带来机遇的同时也带来了挑战,尤其在非标零部件设计方面,一直存在着设计时缺少可直接采用的计算方法、资料和实践数据等问题,致使在非标设备的研发过程中整个设计周期长,制造成本高。为了有效解决上述问题,本文针对企业建立非标零件库并且采用参数化设计思想生成非标零部件模型。本文基于对CATIA软件的研究,以CATIA软件的特征造型技术、二次开发技术和Access数据库技术作为开发方式,选择Visual Basic6.0作为系统的开发平台,再结合企业需求开发了基于CATIA的非标零件库参数化设计系统。本论文首先研究了非标零件库参数化设计思想、设计方法和设计流程,为开发非标零件库参数化设计系统提供理论基础。针对企业现有的零件库中存在分类问题,提出了对非标零件库按照四个层次的分类方式对其进行划分。其次研究了CATIA二次开发技术、VB对CATIA二次开发技术和Access数据库技术等关键技术,且对非标零件库中的所有非标零部件建立三维模型的模板以及设计计算数据表,非标零件数据表,非标产品数据表。最后依据理论基础和关键技术,基于长春合心机械制造技术有限公司开发非标零件库参数化设计系统,并以实例介绍非标零件库系统。实践证明:应用该系统进行非标零部件设计能有效缩短设计周期,降低制造成本,进一步论证本论文研究的理论和关键技术的正确性、有效性。
[Abstract]:In recent years, with the rapid development of manufacturing industry, non-standard equipment is more and more widely used in mechanical equipment, which brings both opportunities and challenges to non-standard enterprises, especially in the design of non-standard parts. There are many problems in design, such as lack of calculation method, data and practice data, which lead to long design cycle and high manufacturing cost in the process of research and development of non-standard equipment. In order to solve the above problems effectively, this paper establishes the non-standard parts library for enterprises and uses the parametric design idea to generate the non-standard parts model. Based on the research of CATIA software, this paper takes the feature modeling technology of CATIA software, the secondary development technology and the Access database technology as the development mode, and chooses Visual Basic6.0 as the development platform of the system. Then the parametric design system of non-standard part library based on CATIA is developed according to the requirements of the enterprise. In this paper, the idea, method and flow of parametric design of non-standard part library are studied firstly, which provides a theoretical basis for the development of parametric design system of non-standard part library. Aiming at the problem of classification in the existing parts library of enterprises, this paper puts forward the classification of non-standard parts library according to the four levels of classification. Secondly, the key technologies such as CATIA secondary development technology, VB secondary development technology for CATIA and Access database technology are studied, and the template of three-dimensional model and design and calculation data table for all non-standard parts in the non-standard part library are established. Non-standard parts data sheet, non-standard product data sheet. Finally, based on the theory foundation and key technology, the parametric design system of non-standard parts library is developed based on Changchun Hexin Machinery Manufacturing Technology Co., Ltd., and an example is given to introduce the non-standard part library system. The application of the system to the design of non-standard parts can effectively shorten the design cycle and reduce the manufacturing cost, and further demonstrate the correctness and effectiveness of the theory and key technologies studied in this paper.
