l PAGE 1 数控机床尾座油压系统设计 机械设计制造及其自动化 学生 指导教师 摘 要：本课题研究的主要目的是设计出与数控机床卧式数控车床相匹配的液压尾座系统，本课题将以其尾座为研究对象，设计出符合该车床的液压尾座。 为了完成本课题的设计，在设计之前的准备工作必须做好，首先是搜集和分析资料，主要包括国内外数控机床的发展现状；液压技术和液压传动系统的基本资料；同等机床液压尾座的图纸和资料等。其次是初步确定液压尾座的总体布局，包括配置形式、液压系统的布置及选择液压能源及相应的配套元件等。最后主要是关于尾座的设计计算。 数控机床顶尖及尾座顶紧和运动的控制方式基本上是手工控制，在通常的加工过程中，需先用手工控制的方式完成运动和卡紧工作。由此可知，在数控机床的加工作效率效率并不高，而且工人劳动强度大，耗时又耗力，还会增加企业成本。因此，本课题研究所要达到的预期效果是在数控车床加工过程中，当需要使用尾座时，使用本课题所设计的尾座可以提高加工过程的机械化和自动化水平，提高生产效率，降低工人的劳动强度，降低企业成本。 关键词：数控机床 尾座 液压系统 液压缸 设计 校核 The design of CNC machine Tailstock Hydraulic system Abstract: The main purpose of the research is based on CNC machine tools to design requirements, designed to match its hydraulic Tailstock to meet the rotation accuracy, rigidity, temperature rise, and so on seismic requirements, to enhance the overall performance of machine tools.?? To accomplish this design, I collected and analysed the information before the design, including domestic and international development of CNC machine tools; hydraulic system of hydraulic technology and the basic information; equal hydraulic machine Tailstock the drawings and information . Then is tentatively determined the overall layout of hydraulic Tailstock, including the allocation of form, layout and the hydraulic system of hydraulic energy, and select the appropriate matching components, such as. This was followed by the main Tailstock the design and calculation. CNC machine Tailstock top tight and movement is basically manual control, in the conventional process, the change required manual. Therefore, in the process of CNC machine tools in efficiency is not high, workers in labor intensity and great. Therefore, the issue of the Institute to achieve the desired results in the CNC lathe processing, when the need to use Tailstock, the use of this issue by the Tailstock design can improve the process of mechanization and automation level, increase production efficiency and reduce Workers in the labor intensity.
