摘要
本文主要阐述了传统钻床PLC改造的可行性,并进行了具体的实施方案,传统钻床传统继电控制系统使用大量的中间继电器、时间继电器,控制触点多,因此电气控制系统存在故障率高、可靠性差、接线复杂、,降低故障率,提高钻床的加工效益,很多企业对传统控制钻床的电气控制系统进行了改造
本文描述了数控机床的基本组成、工作原理、分类及各自的特点。并且对数控机床中的PLC作了详细的介绍,把PLC在数控机床上的控制做了设计。然后以摇臂钻床Z3040为例,描述了它的设计过程,包括控制系统电路的设计,控制原理设计,主电路设计,主控制电路设计,Z3040摇臂钻床原理图,用PLC编写程序对机床进行控制。
关键词:可编程控制器数控机床数字控制液压控制梯形图原理图
ABSTRACT
This article mainly elaborated the traditional machine tool PLC feasibility of transformation, and the specific implementation plan, the traditional machine tools the traditional relay control system using a large number of intermediate relay, time relay, control the contact number, so the electrical control system has a high failure rate, poor reliability, complicated wiring, inconvenient maintenance and other defects. In order to improve machine tool control system reliability, reduce failure rate, improve the machining efficiency, many enterprises to the traditional control machine electrical control system transformation
This paper describes the ponents of NC machine tools, working principle, classification and characteristics on C machine tools in PLC are introduced in detail in this paper, the PLC C machine tool control then to the rocker drilling machine Z3040 as an example, describes its design process, including the control system circuit design, control principle, the design of main circuit, control circuit design, Z3040 radial drilling machine diagram, using PLC programming on the machine tool control.
Keywords: Programmable Controller;NC machine Tools;Digital Control;Sequence Control;Ladder Diagram;Schematic
