摘要

1.铣床概述

铣床是用铣刀对工件进行铣削加工的机床。铣床除能铣削平面、沟槽、轮齿、螺纹和花键轴外，还能加工比较复杂的型面，效率较刨床高，在机械制造和修理部门得到广泛应用。

2.液压技术发展趋势

液压技术是实现现代化传动与控制的关键技术之一，世界各国对液压工业的发展都给予很大重视。液压气动技术具有独特的优点，如:液压技术具有功率传动比大，体积小，频响高，压力、流量可控性好，可柔性传送动力，易实现直线运动等优点；气动传动具有节能、无污染、低成本、安全可靠、结构简单等优点，并易与微电子、电气技术相结合，形成自动控制系统。主要发展趋势如下：

1.减少损耗，充分利用能量

2.泄漏控制

3.污染控制

4.主动维护

5.机电一体化

6.液压CAD技术

7.新材料、新工艺的应用

3. 主要设计内容

本设计是设计专用铣床工作台进给液压系统，本机床是一种适用于小型工件作大批量生产的专用机床。可用端面铣刀，园柱铣刀、园片及各种成型铣刀加工各种类型的小型工件。

设计选择了组成该液压系统的基本液压回路、液压元件，进行了液压系统稳定性校核，绘制了液压系统图，并进行了液压缸的设计。

ABSTRACT

1. Milling machine is general to state

Milling machine is to carry out the machine tool of milling processing with milling cutter for workpiece. Milling machine excludes can milling plane, groove, gear teeth, thread and spline axle are outside, can still process more complex type surface, efficiency has high planer comparatively, when mechanical production and repair department get extensive application.

2. Hydraulic technology develops tendency

Hydraulic technology is that the one of crucial technical, world countries that realize modern transmission and control give great attention to the development of hydraulic industry. Hydraulic pneumatic technology has unique advantage , such as: Hydraulic technology has power weight than is big, volume is little, frequently loud and high, pressure and rate of flow may control sex well, it may be flexible to deliver power , is easy to realize the advantages such as the sport of straight line; Pneumatic transmission has energy saving, free from contamination, low cost and safe reliable, structural simple etc. advantage , and is easy to form automatic control system with microelectronics and electric in technology. Develop tendency mainly to be as follows:

1. Reduce wastage , use energy

2 fully. Leak control

3. Pollute control

4. Defend

5 initiatively. Electromechanical unifinication

6. Hydraulic CAD technical

7. The application of new material and new technology

3. Design content mainly

Quantity of production. May use the garden column milling cutter, garden flat and milling cutter of end panel and is various to process the small-sized workpiece of various types into type milling cutter.

Designing have selected to form hydraulic element and the basically hydraulic loop of this hydraulic system , have carried out hydraulic systematic stability school nucleus , have drawn hydraulic system to seek , and have carried out the design of hydraulic big jar.

Key words milling machine；hydraulic technology；hydraulic system；hydraulic big jar
