Embodiment Construction
[0013] Such as figure 1 Shown: a CNC machine tool fault diagnosis device, which includes a sensor, a signal pick-up circuit, a processing unit, an alarm, an LED indicator light, an LCD display, a drive circuit and a button 8 for setting working parameters;
[0014] The sensor is installed on the CNC machine tool 1, and the signal pickup circuit 2 processes the signal detected by the sensor to form a standard signal input processing unit. The processing unit 3 compares the input signal with the characteristic value, and the value exceeding the set value will pass through the alarm 4 and the LED indicator light 5 send an alarm message, and the information is displayed on the LCD display 6 through the drive circuit 7 at the same time; the processing unit is a STC single-chip microcomputer.
[0015] The fault diagnosis device is connected with the CNC machine tool. Some signal collection points are set on the CNC machine tool. The information of these collection points is input in...
