Welding head base gap measuring device of ultrasonic welding machine

The utility model discloses a device for measuring a gap between a welding head and a base of an ultrasonic welding machine, the device comprises a welding head and a base, the welding head can move back and forth along the direction of the welding head pointing to the base, the device is characterized by further comprising a distance measuring device and a welding head adjusting screw, and the distance measuring device is used for measuring the distance between the lower surface of the welding head and the upper surface of the base; the welding head adjusting screw is fixed on the welding head, and the height of the welding head can be adjusted by rotating the welding head adjusting screw. By means of the integrated distance measuring device, the real gap condition between the welding head and the base and between the welding head and the base in the working process can be directly detected, adjustment data can be displayed in real time when the gap is adjusted, and therefore the gap can be rapidly and accur
