基于Z3040型摇臂钻床PLC控制系统

加密芯片摘要

Z3040型摇臂钻床适用于单件或批量生产带有多孔的大型零件的孔加工，是机械加工车间常用的机床，在机械行业中得到了广泛应用。由于传统继电器,接触器控制的摇臂钻床存在电路接线复杂，触点多、噪音大、可靠性差、故障诊断与排除困难等缺点，因此对Z3040摇臂钻床控制系统的技术改造是非常必要的。

本文在分析Z3040型摇臂钻床继电接触控制系统工作原理的基础上，提出了用可编程控制器(PLC)对摇臂钻床控制系统进行改造设计。文中介绍了PLC的原理和特点;给出了摇臂钻床PLC控制系统的硬件组成和软件设计;其中包括PLC的选型、输入/输出(I/O)地址分配、PLC外部接线图、PLC梯形图程序设计;分析了用PLC控制摇臂钻床的工作过程;对主要电器元件进行了选择。

改造后的Z3040型摇臂钻床简化了控制线路，使机床功能完善，使用方便，维护简单，降低了设备运行的故障率，提高了设备运行的使用率，可实现生产过程的高效、节能和低成本。在工业上有广泛的应用前景。

Abstract

逃生系统

The Z3040 drilling lathe which was commonly seen in workhouse, and it is widely used in mechanism industry. There were too many faults in the traditional relay controlled drilling lathe, such as the complex connections in circuit; too much noises and so on, besides these hidden problems ,the diagnosing and expelling for the mistakes w as also difficult. it is necessary to improve its controlling system in technical.

This article propose using the Programmable Logic Controller (PLC) to replace the traditional control system which was compounded of relays, and this control theory was based on the function of relays. it shows the principle and unique of the PLC ;also shows both hardware structure and software of the new Z3040 drilling lathe which was controlled by The PLC, including allocation for input/output address, external connection diagram, designs for programs.

Through analyses the procedure that the Z3040 works, I chased main components.

Through the improvement, we simplify the control system, it both perfect the function and cut down costs which was used for maintenances. The reform of Z3040 can easily help us to realize low-cost and energy-costless during the production, it has gorgeous prospects in industry.
