文档介绍：MJ-50型数控车床电动刀架设计
摘要
数控车床今后将向中高当发展,中档采用普及型数控刀架配套,高档采用动力型刀架,兼有液压刀架、伺服刀架、立式刀架等品种,预计近年来对数控刀架需求量将大大增加。数控刀架的发展趋势是:随着数控车床的发展,数控刀架开始向快速换刀、电液组合驱动和伺服驱动方向发展。
本部分主要对四工位电动刀架的机械设计和应用继电-接触控制系统控制部分的设计。并对以上部分运用AUTOCAD做图,对电动刀架有更直观的了解。最后的提出了对电动刀架提出了意见和措施。

Abstract
Numerical control there is in the future lathe to in will develop, the middle-grade to adopt popular numerical control knife rest form plete set, adopt the motive force type knife rest top-grandly, have such varieties as knife rest of hydraulic pressure, servo knife rest, vertical knife rest ,etc. concurrently, it is estimated that will increase to numerical control knife rest demand greatly in recent years. The development trend of the numerical control knife rest is: With the development of numerical control lathe, numerical control knife rest begin to change one hundred sheets , electric liquid is it urge and urge direction develop while being servo to make up fast. Some originally design and is it continue electricity to use to four worker location vertical electronic machinery of knife rest mainly- exposed to control system control some designs. And use AUTOCAD to pursue to the above part, have a more ocular knowledge of electronic knife rest. The last proposition has put forward the suggestion and measure to the electronic knife rest.

前言
数控车床为了能在工件的一次装夹中完成多工序加工,缩短辅助时间,减少多次装夹所引起的加工误差,必须带有电动刀架。
电动刀架在结构上必须具有良好的强度和刚性,以承受粗加工时的切削抗力。为了保证转位之后具有高的重复定位精度,电动刀架还要选择可靠的定位方案和合理的定位结构。电动刀架的自动换刀是由控制系统和驱动电路来实现的。
