铣床的X-Y轴进给系统及其仿真.docVIP

摘 要 随着科学与技术的发展，加工技术在世界的工业范围内都有了显著的提高。而我国以加工中心为代表的高自动化、高附加值、高利润的机床产品却远远落后于世界机床同行。随着中国经济的持续发展,机床行业的全球化、以及在政府加强自主知识创新举措的鼓励下，投资开发加工中心等高档机床的时机趋于成熟。 本次设计是设计铣床的X-Y轴进给系统及其仿真。首先，了解铣床的结构，确定方案。其次，选择滚珠丝杠、步进电机和消隙齿轮等零件，来达到提高传动精度，减小加工误差的目的。本次设计的结果可以顺利达到设计任务的要求，完成X、Y两方向单独运行和同时运行，提高了加工效率。 论文研究完成了基于虚拟样机的网架节点球立式加工中心本体设计—X轴和Y轴及其仿真设计，形成机床详细结构设计的指导文件，为设计的全面铺开实施奠定了基础。 关键词: 立式加工中心; 机床结构; 总体设计; 进给系统; Abstract With the development of science and technology, processing technology in the world with the industry-wide have improved significantly. In China, the representative of a processing center for high automation, high value-added, high profit machine the world has fallen far behind the peer machine. With Chinas sustained economic development, the globalization of the machine tool industry, as well as knowledge of the Government to strengthen the autonomy of the encouragement of innovation, investment and development centers, such as processing time for high-end machine tools mature. The design is the design of the xy-axis milling machine feed system and its simulation. First of all, to understand the structure of milling machine to determine the program. Secondly, the choice of ball screws, stepper motors and anti-backlash gear such as spare parts, to achieve to improve the accuracy of transmission, the purpose of reducing the processing error. The results can be successfully designed to meet the design requirements of the task, the completion of X, Y two directions at the same time running a separate operation and improved processing efficiency. Completion of the study paper-based virtual prototyping of network nodes Ontology ball vertical machining center design-X-axis and Y axis and the simulation design, detailed structural design of machine tools to form the guiding document for the design of the implementation of a comprehensive way and laid the foundation.
