Nozzle mounting structure with a double-cooling type height sensor for laser processing head

Abstract

The invention discloses a nozzle mounting structure with a double-cooling type height sensor for a laser processing head. The nozzle mounting structure comprises a cooling built-in height sensor, an outer cooling sleeve arranged outside the cooling built-in height sensor in a sleeving manner, a ceramic body mounting seat arranged at the bottom of the cooling built-in height sensor, a mounting seat locking ring for locking the ceramic body mounting seat on the cooling built-in height sensor, a nozzle mounting seat mounted on the ceramic body mounting seat, a ceramic body locking ring used for locking the nozzle mounting seat on the ceramic body mounting seat, and a nozzle mounted on the nozzle mounting seat; and the cooling built-in height sensor, the ceramic body mounting seat, the nozzle mounting seat and the middle of the whole nozzle are vertically through to form a laser channel for light beams to pass through. According to the nozzle mounting structure, the working temperature of the internal structure of the height sensor is always kept in a relatively stable range.

Description

【Technical field】 [0001] The invention belongs to the technical field of laser processing heads, and in particular relates to a nozzle mounting structure for a laser processing head with double cooling height sensors. 【Background technique】 [0002] At present, most of the laser cutting is to melt and evaporate the workpiece through the energy released when the beam is irradiated on the surface of the workpiece. During the cutting process, the distance between the cutting nozzle and the plate needs to be controlled at a constant value, and the most critical component to achieve this purpose is the height sensor. The huge heat generated by cutting will affect the electronic components inside the sensitivity sensor. Working accuracy, because of the accuracy, the cutting effect will be unsatisfactory or the normal cutting work cannot be carried out, which will affect the cutting production efficiency; at the same time, the plate slag that appears during the cutting process will...

Problems solved by technology

[0002] At present, most of the laser cutting is to melt and evaporate the workpiece through the energy released when the beam is irradiated on the surface of the workpiece. During the cutting process, the distance between the cutting nozzle and the plate needs to be controlled at a constant value, and the most critical component to achieve this purpose is the height sensor. The huge heat generated by cutting will affect the electronic components inside the sensitivity sensor. Working accuracy, because of the accuracy, the cutting effect will be unsatisfactory or the normal cutting work cannot be carried out, which will affect the cutting production efficiency; at the same time, the plate slag that appears during the cutting process will stick to the surface of the height sensor, thus affecting the positioning accuracy and damage the sensor appearance

At present, some common solutions in the market to reduce the influence of plate heat radiation on the height sensor are to increase air cooling inside the height sensor, but the cooling effect of this solution may not meet the cooling requirements, and it cannot guarantee that the height sensor is free from cutting reactions. The effect of slag
