【摘要】 随着科技的发展,继电器-接触器机床控制方式已经越来越不能满足要求,到目前为止我国大部分机床还是以传统的机床为主,利用传统机床进行现代化改造已经刻不容缓,而运用PLC-触摸屏的控制方式对数控机床电气部分进行改造,不仅提高机床的加工效率,同时提高了普通机床的可靠性。本文以传统的车床为研究对象,对传统机床电气部分进行智能化改造,主要研究内容为:本文主要是运用PLC与触摸屏组合实现对普通机床的智能化控制,PLC主要是对传统机床的继电器-接触器这种控制模式进行改造,利用PLC的逻辑控制取代传统的继电器控制,不仅可以增加机床的控制功能,同时利用可编程逻辑控制器减少了外部接线,降低了机床的故障率。改造后的车床电气部分功能为:机床回零,主轴控制,X及Z的控制,润滑控制,报警,自动换刀,冷却等功能。同时利用触摸屏与PLC配合,更加方便的对传统机床数控化改造后的控制,触摸屏主要控制页面分为:开机画面,主轴控制界面,冷却控制界面,快进控制界面。其中报警等插入在各控制页面中,方便在控制的时候进行电机状态的监控。更多还原

【Abstract】 With the development of science and technology,the control mode of relay-contactor machine tools has been increasingly unable to meet the requirements.So far,most of our machine tools are still dominated by traditional machine tools.It is urgent to modernize the traditional machine tools.Using the control mode of PLC-touch screen to reform the electrical part of CNC machine tools not only improves the processing efficiency of machine tools,but also improves the processing efficiency of CNC machine tools.The reliability of common machine tools is improved.This paper takes the traditional lathe as the research object and intellectualizes the electrical part of the traditional machine tool.The main research contents are as follows:This paper mainly uses the combination of PLC and touch screen to realize the intellectualized control of the ordinary machine tool.PLC mainly reforms the relay-contactor control mode of the traditional machine tool,and uses the logic control of PLC to replace the traditional relay control,not only can it be used.In order to increase the control function of machine tools,programmable logic controller is used to reduce the external wiring and the failure rate of machine tools.The electrical functions of the reformed lathe are as follows: machine tool return to zero,spindle control,X and Z control,lubrication control,alarm,automatic tool change,cooling and other functions.At the same time,using touch screen and PLC,it is more convenient to control the traditional machine tool after numerical control transformation.The main control pages of touch screen are divided into: boot screen,spindle control interface,cooling control interface,fast forward control interface.The alarm is inserted into the control pages to facilitate the monitoring of the motor state in the control time.更多还原
