液压缸变速式数控车床主传动系统设计 ? Design on the Main Axle Driving System of CNC controled by the Hydraulic cylinder 专 业：机械设计制造及其自动化 学 生 姓 名： 学 号： 指 导 教 师： 完 成 日 期：二00九年六月十日 济南大学泉城学院 摘 要 数控机床是现代化机械制造企业所必需的重要设备数控技术PLC技术、工业机器人并称为工业自动控制的三大支柱ABSTRACT The numerical control engine tools is the important equipment which the modernized machine manufacture enterprise must.The numerical control technology, PLC technology, industry robot are the three big important part. The development numerical control technology is for overcome the human operators limitation, moreover he has completed this work truly. The numerical control engine bed is higher than the manual control ordinary engine bed precision, the components uniformity which produces is better, the production speed is quicker, moreover the long-term craft equipment cost is lower. The numerical control also causes them to use the manual control the senior use to be more widespread than. A numerical control engine bed may the automatic production very many type components, each components all be possible to have different and the complex processing. This design of automatic transmission is base on hydraulic cylinders, piston rod fork-led movement to promote the realization of sliding gear transmission and change the rotational speed, thus can achieve the main axle the big speed change scope. The engine bed main axle actuates to use the exchange frequency conversion velocity modulation electrical machinery. Key words：CNC machine；CVT；hydraulic cylinder 目 录 摘要………………………………………………………………..…….….…………….. .I ABSTRACT…………….……………………..…………….II 1 前言……………...……….…………………………………………….….……………..1 1.1数控机床的发展史...........................……….......…………….………….………..1 1.2数控机床的工作原理................................………….………….………..3 1.2.1 数控机床的构成................................………….………….………………..3 1.2.2 数控系统的分类................................………….………….………………..3 1.3 数控机床的优点......................……
