Laser robot cutting device

The utility model belongs to the technical field of laser cutting, and particularly relates to a laser robot cutting device which comprises a mechanical arm and a cutting table, a laser cutting head is arranged on the mechanical arm and comprises a nozzle and a focusing lens, and a water cavity is arranged between the nozzle and the focusing lens. A first supporting table, a second supporting table, a first sliding table and a second sliding table are arranged on the cutting table. According to the laser robot cutting device provided by the utility model, when the laser beam is ejected from the nozzle, water in the water cavity can be ejected along with the laser beam, the laser beam is spread to the surface of a workpiece from the nozzle along a micron-sized water beam, the laser is used for ablating the workpiece, and the water beam can be used for cooling a cutting area and washing and removing laser ablated chips in time; heat accumulation and burrs generated in the cutting process are few, and the surfac
