【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。更多还原

【Abstract】 No oil vortex compressor is the latest model of air compressor in recent years, and it has small volume, light weight, novel structure, low noise, smooth continuous gas, long life, easy operation, less maintenance costs, and so on advantage, compared with the traditional air compressor, be inline known as "no maintenance air compressor" and "new revolution air compressor", is widely used in many fields and some special working conditions. Because of the particularity of itself, the parts’ processing and assembly accuracy requirement is high, and the production quality is difficult to control, so enterprise batch production target is difficult to achieve. Therefore, the detection and management to no oil compressor parts, and the research and implementation of assembly scheme has very vital significance.This paper has designed and developed tolerance and assembly management system, based on Visual Studio2008platform and SQL Sever2005software. Focused on the following aspects of research:analyzing the structure, working principle, performance requirements and other factors of no oil compressor, put forward the key parts of the test items and tolerance requirement, clear system requirements; Using structured analysis method and the application of UML modeling technique, established the system’s information model, including the system class diagram, characteristic model and data model; Both at home and abroad to related form errors of the research situation, analyzed the error modeling, and designed the least square method based on the evaluation algorithm, and clear the algorithm process; Designed the system architecture, planned and researched coding method, used.NET and Matlab programming to realize complex calculation and mixed figure show function, and designed object-oriented hierarchical coding method, based on the three layer structure, improve the maintainability of the system.This paper builds up the data set computing and graphics display for the integration of tolerance management system, and makes drawings information management, testing, assembly information management and tolerance management combine, becomes into the contact of detection system, simulation system and assembly lines, and improves the enterprise’s information management level.更多还原
