Referring to fig. 2, the telescopic distance of the telescopic rod of the cylinder in the drawing is zero, and the state of the thickness measuring device is defined as state three. The thickness measuring device is arranged in front of the feeding and discharging device of the laser cutting machine, single feeding is required to be guaranteed at each time, so that thick bottom measurement needs to be carried out on a plate before feeding, and the fact that the feeding plate is a single plate is guaranteed. There are two main ways of measurement, as follows:

the first method is as follows: firstly, the thickness measuring device of the embodiment is adjusted to the second state, the telescopic rod of the cylinder extends for a certain distance, so that the contact part on the guide rod is contacted with the contact part on the clamping hook, namely, the second state is the initial state. When carrying out the thickness measurement to panel, the cylinder telescopic link shrink, during panel that awaits measuring was moved the thickness measurement device, the telescopic link adjustment flexible state of cylinder made the contact site all contact with panel, formed measurement space h, measurement space h this moment is the thickness of panel, and the final stroke of magnetic induction switch response on the cylinder and feedback cylinder telescopic link turns into measured data with the stroke of feedback, and this data is the thickness of panel that records promptly.

The second method comprises the following steps: the telescopic distance of a telescopic rod of an air cylinder of the thickness measuring device is enabled to be zero, namely the initial state is a state three, the telescopic rod of the air cylinder starts to extend out to drive a clamping hook to rotate until the clamping hook reaches a limit position, namely a state two, a magnetic induction switch induces and feeds back the stroke of the telescopic rod at the moment, the fed-back stroke is converted into measurement data I, the data I at the moment is recorded and stored, the data only needs to be repeated once, and the measurement data I at the step does not need to be re-read in subsequent multiple measurements; the cylinder telescopic link contracts, the thickness measuring device returns to the initial state of the state III, after the measured plate moves into the thickness measuring device, the cylinder telescopic link extends out to drive the clamping hook to rotate, a measuring space h is formed, namely the thickness measuring device reaches the state I, the measuring space h is the thickness of the plate, the magnetic induction switch induces and feeds back the final stroke of the cylinder telescopic link from the state III to the state I of the thickness measuring device, the fed-back stroke is converted into the measurement data II, and the subtraction of the measurement data I and the measurement data II is the thickness of the measured plate.

The foregoing is only a preferred embodiment of the present invention, which is illustrative, not limiting.
