基于PLC机床电路的改造与设计
摘 要:本设计是对C650卧式普通车床的电气控制系统进行的PLC数控改造,用学校的德国西门子S7-200系列PLC来控制C650卧式车床。PLC技术近年来使用频率很高,而且该技术以其结构简单、易于编程的优点,是我们对机床电路的改造必不可少的。利用该技术,我们可以快速修复和改善机床及其他设备,修复现有的问题,在实际生产过程中得到广泛的借鉴。虽然这项技术的优势虽然相对较高,但仍存在不足,这就要求让我们在实践的过程中,根据在深入思考和探索过程中存在的问题,对该技术的不足进行改进,从而提高改造的效率和水平。我先用CAD制图软件把C650卧式车床的主电路和控制电路画了一下,然后我把它的PLC外部接线图也用CAD软件画了出来。然后用V4软件把PLC的梯形图画了出来,画完以后编译了一下,用电脑上的仿真软件根据I/O分配表操作了一遍,最后用组态王软件把程序编译成监控状态,完成整个设计。

The reform and design of machine tool circuit based on PLC
Abstract:This design is the electrical control system of the electric control system of c650 horizontal lathe, the german Siemens S7 - 200 series PLC to control c650 horiz- ontal lathe. Plc technology in recent years is very high frequency, and the technology with its simple structure, easy to program the advantages of our machine tool circuit is essential. Using this technology, we can quickly repair and improve the machine and other equipment, repair the existing problems, and get extensive reference in the actu- al production process. Although the advantage of this technology is relatively high, but there are still shortcomings, which requires us in the process of practice, according to the problems in the process of thinking and exploration, to improve the shortage of the technology, so as to improve the efficiency and level of transformation. I first dre- w the main circuit and control circuit of the c650 horizontal lathe with CAD drawing software, and then I drew out its PLC external wiring diagram with CAD software. Then use v4 software to draw the ladder diagram of PLC, after the compilat- ion, the computer simulation software according to the I / o distribution table operation,finally using the kingview software to compile the monitoring status, complete the whole design.
Keywords: Programmable controller(PLC);Kingview ;Nc machine tool
