数控车床转位刀架控制电路的改进

The Solid Relay's Application in the Control Circuit of lathe's Toe Intex Carriage

本文从数控车床转位刀架控制电路的改进出发 ,介绍了一种利用固体继电器控制的电机正反转控制电路 ,与传统的交流接触器控制电路相比 ,该电路具有工作可靠、寿命长、对外界干扰小、抗干扰能力强、并符合“本质安全性”要求等一系列特点。

Setting out from the control electric circuit's improvement of NC lathe's toe index carriage,this paper introduces a Control circuit of electric motor's revolution and counter revolution,which utilizes solid relays.Comparing with AC contactor's control circuit this kind of control circuit has higher working reliability,longer life-span,slighter disturbance,stronger ability of antijamming and accords with the characteristic of nature-safety completely.
