Description

A laser cutting device for protective housings Technical Field

[0001] This utility model relates to the field of laser cutting technology, and in particular to a laser cutting device for protective housings. Background Technology

[0002] Protective housings are widely used in various mechanical equipment, such as PC machinery, industrial automation equipment, and CNC machine tools. They play a vital protective role in these devices, ensuring the normal operation of the equipment and the safety of the operators. These protective housings are cut using a laser cutting machine. Laser cutting technology is an advanced material processing technology that uses a high-power-density laser beam to irradiate the material being cut, rapidly heating it to its vaporization temperature and causing it to evaporate and form holes. As the beam moves, the holes continuously form narrow kerfs, thus completing the cutting of the material.

[0003] Existing laser cutting devices for protective housings can only fix the two sides of the protective housing, not the four sides. This causes the protective housing to move or shake during the cutting process, which greatly reduces the cutting quality and limits its practicality. Therefore, we propose a laser cutting device for protective housings to solve this problem. Summary of the Invention

[0004] The purpose of this invention is to provide a laser cutting device for protective housings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:
