【摘要】：无油涡旋压缩机以其独特的结构和性能优势广泛应用于多领域和一些特殊工作条件下,被行内誉为“无需维修空气压缩机”和“新革命空气压缩机”。由于它本身的特殊性,零件的加工精度和装配精度要求高,生产质量难控制,企业批量生产目标难实现。因此,对无油涡旋压缩机零件形位公差的检测与管理,及装配方案的研究与执行具有十分重要的意义。论文基于Visual Studio2008平台和SQL Sever2005软件设计开发了公差与装配管理系统,并建立了面向对象的特征数据库。主要进行了以下方面的研究：分析研究无油涡旋压缩机结构、工作原理、性能要求等因素,提出关键零件检测项与公差要求,明确系统需求；应用结构化分析方法与UML建模技术结合,建立了系统的信息模型,包括系统类图、特征模型和数据模型；结合国内外对相关形位误差的研究现状,进行了误差建模分析,并设计了以最小二乘法为基础的评定算法,理清了算法流程；进行了系统架构设计、界面规划及编码方式的研究,采用了.NET与Matlab混合编程实现复杂计算与图显功能,并且设计了基于三层架构的面向对象的分层编码方式,提高了系统的可维护性。论文构建了集数据计算与图形显示为一体的公差管理系统,将图纸信息管理、检测信息管理、装配管理与公差管理结合为一体,成为联系检测系统、模拟仿真系统和装配生产线的纽带,提高了系统的灵活性和可扩展性,提高了企业的信息化管理水平。
[Abstract]:The oil-free scroll compressor is widely used in many fields and some special working conditions because of its unique structure and performance advantages. It is praised as "no maintenance air compressor" and "new revolutionary air compressor" in the industry. Because of its particularity, the machining accuracy and assembly precision of parts are high, the quality of production is difficult to control, and the goal of batch production is difficult to be realized. Therefore, it is of great significance to detect and manage the shape and position tolerance of the parts of the oil-free scroll compressor, and to study and implement the assembly scheme. The tolerance and assembly management system is designed and developed based on Visual Studio2008 platform and SQL Sever2005 software, and an object-oriented feature database is established. The main research is as follows: analyze and study the structure, working principle, performance requirements of oil-free scroll compressor, put forward the key parts inspection items and tolerance requirements, clarify the system requirements; The information model of the system, including system class diagram, feature model and data model, is established by combining the structural analysis method with UML modeling technology, and the error modeling analysis is carried out according to the current situation of the research on the related form and position error at home and abroad. The evaluation algorithm based on the least square method is designed, the algorithm flow is clarified, the system architecture design, the interface planning and the coding method are studied, and the functions of complex calculation and graph display are realized by the mixed programming of .NET and Matlab. An object-oriented hierarchical coding method based on three-tier architecture is designed to improve the maintainability of the system. In this paper, a tolerance management system, which integrates data calculation and graphic display, is constructed. Drawing information management, inspection information management, assembly management and tolerance management are integrated into a contact detection system. The link between simulation system and assembly line improves the flexibility and expansibility of the system, and improves the level of information management of enterprises.
