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，是一般機械加工車間常用的機床。由于其控制系統(tǒng)采用繼電器控制方式，電路接線復雜、觸點多。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。因此對Z3040搖臂轉床的PLC改造有特別重要的意義。PLC具有可靠性高，環(huán)境適應性強，使用方便，維護簡單等優(yōu)點。因此，利用PLC對搖臂鉆床繼電器電路進行設計，有助于提高設備的可靠性。本文分別對Z3040搖臂轉床的主軸電動機的控制，搖臂的上升、下降以及主軸箱、立柱的松開和夾緊進行PLC改造。最后繪制出梯形圖和I/O接口圖。

關鍵詞：Z3040搖臂轉床 ；電氣控制系統(tǒng)；PLC改造

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
