摘 要

近年来，液压传动由于应用了计算机技术、信息技术、自动控制技术、新材料等后取得了新的发展，使液压系统和元件正向高压、高速、高精度、高效率的方向发展，在完善比例控制、伺服控制、数字控制等技术上取得新的成就。液压系统的发展方向是：创制新型节能、微型元件﹑高度的组合化、集成化和模块化和微电子结合，走向智能化。

液压技术是机械设备中发展最快的技术之一。特别是近年来与微电子、计算机技术相结合，使液压气动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、气动元器件制造技术的进一步提高，使液压气动技术不仅作为一种基本的传动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。

本设计中的以液压方式控制组合机床的动力滑台，克服了使用机械传远距离传动所造成的装置过于庞大的缺点，以其简单的方式实现了工作要求。

综上所述，液压工业在国民经济中的作用是很大的，它常常用来衡量一个国家工业水平的重要标志之一。与世界上主要的工业国家相比，我国的液压工业还有相当差距，化、优质化的工作有待于继续做好，智能化的工作刚刚起步，为此必须急起直追，才能迎头赶上。

Abstract

modularization, integration and modularization and microelectronics, become smarter.

Hydraulic technology is one of the fastest growing technology in mechanical equipment. Especially in recent years and the combination of microelectronics, computer technology, make the hydraulic pneumatic technology has entered a new stage of development. At present, has been widely used in industry in various fields. In recent years due to the development of microelectronics, computer technology, hydraulic and pneumatic components manufacturing technology to further improve, make the hydraulic pneumatic technology not only plays a crucial role as a basic form of transmission, and with good static and dynamic performance has become an important means of control.

By hydraulic control in the design of the modular machine tool power sliding table, overcome the use of mechanical transmission caused by the remote transmission device is too big shortcomings, achieve the job requirements in the simple way.

Above all, the role of hydraulic industry in the national economy is great, it is often used to measure a nation's industrial level is one of the important marks. Compared with the world's major industrial countries, there is quite a gap between the hydraulic industry in China, and the varieties of work to be to continue to do intelligent work has just started, so have to play catch-up, to catch up.
