Z3040搖臂鉆床的PLC改造

摘  要
Z3040搖臂鉆床是我國使用較多的鉆床，是一般機(jī)械加工車間常用的機(jī)床。由于其控制系統(tǒng)采用繼電器控制方式，電路接線復(fù)雜、觸點(diǎn)多。長期使用后，故障率高，故障排查困難，常常影響企業(yè)的正常生產(chǎn)。因此對Z3040搖臂轉(zhuǎn)床的PLC改造有特別重要的意義。PLC具有可靠性高，環(huán)境適應(yīng)性強(qiáng)，使用方便，維護(hù)簡單等優(yōu)點(diǎn)。因此，利用PLC對搖臂鉆床繼電器電路進(jìn)行設(shè)計(jì)，有助于提高設(shè)備的可靠性。本文分別對Z3040搖臂轉(zhuǎn)床的主軸電動機(jī)的控制，搖臂的上升、下降以及主軸箱、立柱的松開和夾緊進(jìn)行PLC改造。最后繪制出梯形圖和I/O接口圖。

Z3040 Rocker Switch To The Bed PLC Reconstruction

Abstract
Radial Drilling Machine Z3040 is China's use of more drilling, is commonly used in general machining machine tool shop.  Because of its control system uses relay control mode, circuit wiring complex, multi-touch.  Long-term use the failure rate is high, troubleshooting problems and often affect failure the normal production.  Therefore Z3040 rocker switch to the bed PLC transformation of special importance.  PLC has a high reliability, environmental adaptability, easy to use, easy maintenance and so on.  Therefore, the use of PLC relay circuit for radial drilling machine is designed to help improve equipment reliability.  In this paper, rocker switch on the Z3040 bed spindle motor control arm rise, decline and spindle boxes, columns of the release and clamping to PLC reconstruction.  Finally draw the ladder, and I / O interface map.
Key words: Z3040 Rocker Switch Beds;Electrical Control System;PLC Reconstruction
