Abstract

This utility model provides a laser cutting head, relating to the field of laser cutting head technology, comprising: a laser cutting instrument; a positioning seat fixedly installed at the lower end of the laser cutting instrument, with an assembly hole at the center of the positioning seat, and the cutting head body disposed inside the assembly hole. This utility model achieves efficient circulation of the cooling medium by setting up a cooling circuit consisting of a cooling device and a cooling chamber. The cooling medium provided by the water tank, under the power of the water pump, enters the cooling chamber of the cutting head body through a hose, sliding tube, and positioning tube, continuously removing the large amount of heat generated by the cutting head during operation. This effectively solves the problem of overheating of the cutting head during laser cutting, avoiding aging and damage of internal optical components, deformation of structural parts, and equipment failure caused by high temperatures, extending the service life of the cutting head, and ensuring the stability of laser focusing accuracy and cutting quality.
