机械加工用电磁感应检测法进行粗基准定位,在大批量生产中十分方便。它是在定位工装上安装若干个电感式传感器。定位时,传感器产生的交变磁通穿过工件基准面,构成传感器磁路的一部分。此时工件基准位置的偏移引起传感器电系数的改变;传感电桥输出与它相应的电讯号,经测量线路的处理,检测仪输出
Machining with electromagnetic induction detection method for rough positioning, in high volume production is very convenient. It is installed in the positioning tool installed on a number of inductive sensors. When positioned, the alternating magnetic flux generated by the sensor passes through the workpiece datum and forms part of the sensor’s magnetic circuit. The deviation of the reference position of the workpiece at this time causes the change of the electrical coefficient of the sensor; the sensing bridge outputs the electrical signal corresponding to it, and the output of the tester is processed by the measuring circuit
