Amorphous alloy iron core on-line thickness measuring device and method

The invention relates to the technical measuring device field, and specifically relates to an amorphous alloy iron core on-line thickness measuring device and method, the device comprises a housing, a measuring device, a screening device and a driving device, the measuring device is slidably arranged on the inner top surface of the housing, the screening device is arranged on the inner bottom surface of the housing, the driving device is arranged on the top surface of the measuring device, and the driving device is arranged on the inner bottom surface of the housing. According to the iron core stacking thickness detection device, the ejector pins abut against the surfaces of iron cores correspondingly, the flat bottom plate is matched, whether the stacking thickness error of the iron cores meets the standard or not can be directly obtained through the ejection distances of the ejector pins, and operation is easy and convenient; through cooperative use of the measuring device and the screening device, iron cor
