描述

数控机床可用测量法对主轴轴承温度进行监测。通过测量主轴轴承运转中的温升，来了解主轴轴承是否正常。轴承温度一般限制在温度升高不超过45℃，监测中若发现轴承的温度超过70-80℃，应立即停机检查。

1安装及接线

数控机床可利用热电阻、多通道数字仪表及PLC控制系统的结合，来实现主轴轴承温度的检测。

在主轴前、中、后轴承处，安装4个热电阻。PLC控制系统采集4个测量点的温度，来监测不同位置处轴承温升情况。

2控制要求及原理

温度控制系统利用热电阻进行测量点的温度测量，利用多通道数字仪表来显示主轴轴承的温度值。PLC实现参数设定、远程监控、数据存储和报警处理等功能。在实际编程过程中，不需要编写读写PLC寄存器的程序，通过数据定义的方法，在定义了I/O变量后，可直接使用变量名用于系统控制、操作显示、数据记录和报警等。

系统设置一个启动按钮来启动控制程序，设置红、绿2个指示灯来显示温度状态。4个测量点的温度在要求范围内，绿灯亮，表示主轴可正常运转；当某一个被测点温度达到上限时，即便主轴转速还未达到要求，则红灯亮，同时数控系统显示器上相对应的轴承报警。操作者将主轴立即停止运转，并根据对应报警号检查主轴轴承对应位置处的状况，从而避免主轴轴承研伤现象。

3结束语

现代PLC具有功能强、集成度高、抗干扰能力强、组态灵活、工作稳定等显著特点，广泛应用于现代工业的自动控制中。PLC可扩展一些智能控制模块，构成不同的控制系统，本文提到的主轴轴承温度的检测就是以PLC为核心的智能温度控制系统，操作方便，可靠性好，具有重要的现实意义。
