【摘要】 本论文主要阐述了组合机床动力滑台液压系统，能实现的工作循环是：快速前进 工作进给 快速退回 原位停止压技术是机械设备中发展速度最快的技术之一。特别是近年可与微电子、计算机技术相结合、使液压技术进入了一个新的发展阶段。目前，已广泛应用在工业各领域。由于近年来微电子、计算机技术的发展，液压元器件制造技术的进一步提高，使液压技术不仅在作为一种基本的传统形式上占有重要地位而且以优良的静态、动态性能成为一种重要的控制手段。面对我国经济近年来的快速发展，机械制造工业的壮大，在国民经济中占重要地位的制造业领域得以健康快速的发展。制造装备的改进，使得作为制造工业重要设备的各类机加工艺装备也有了许多新的变化，尤其是孔加工，其在今天的液压系统的地位越来越重要。液压系统的设计，除了满足主机在动作和性能方面规定的要求外，还必须符合体积小、重量轻、成本低、效率高、结构简单、工作可靠、使用和维修方便等一些公认的普遍设计原则。液压系统的设计主要是根据已知的条件，来确定液压工作方案、液压流量、压力和液压泵及其它元件的设计。 综上所述，完成整个设计过程需要进行一系列艰巨的工作。设计者首先应树立正确的设计思想，努力掌握先进的科学技术知识和科学的辩证的思想方法。同时，还要坚持理论联系实际，并在实践中不断总结和积累设计经验，向有关领域的科技工作者和从事生产实践的工作者学习，不断发展和创新，才能较好地完成机械设计任务。 关键词　组合机床 液压系统 液压缸 液压泵换向阀 The face of Chinas economy developed rapidly in recent years, the growth of machinery manufacturing industry, in the national economy accounts for an important position in the field of manufacturing industry to be healthy and rapid development. Improvement of manufacturing equipment, making an important equipment manufacturing industry as a wide range of machining processes and equipment have been many new changes, especially the hole processing, in todays hydraulic system is becoming more and more important. Boring machine hydraulic system design, in addition to the host in action and meet the performance requirements of the provisions, but also must meet the small size, light weight, low cost, high efficiency, simple structure, reliable operation, convenient use and maintenance of a number of generally recognized design principles. The design of the hydraulic system is the basis of known conditions to determine the work program of hydraulic, hydraulic flow, pressure and hydraulic pumps and other components of the design. To sum up, the need to complete the entire design process to conduct a series of hard work. In recent years, in particular with the microelectronics, computer technology, so that the hydraulic technology has entered a new stage of development. At present, it has been widely used in industry in various fields. In recent years, micr
