一种机床电路自动控制器的设计

Design of an Automatic Circuit Controller for Machine Tools

针对普通机床等传统控制电路的工作可靠性差,维修难度比较高,用可编程控制器改造费效比不高,使用维护技术要求高等的不足,设计一种机床电路自动控制器,以单片机为核心,运算能力要求不高,设插卡、输入接口供控制程序输入与更新,可直接驱动交流接触器工作,并融入交流接触器的交流吸合、直流保持的节电技术,以简化机床电路的结构、提高可靠性并降低造价和运行费用。

Aiming at the problems of poor reliability and difficulty in maintenance of traditional control circuits, such as general machine tools,the design of a machine tool circuit automatic controller based on programmable logic contrailer （ PLC） is presented,which uses the programmable controller to improve the cost-to-performance ratio andthe high maintenance and technical requirements. As the core, running capacity is not high, set the card, the input interface for the control program input and update, can direcdy drive AC contactor work, and into the AC contactor AC pull, DC to maintain energy-saving technology to simplify the machine circuit structure, improve reliability and reduce the cost and operating costs.
