Description

Technical Field

[0001] The utility model belongs to the technical field of laser cutting heads and relates to a laser cutting head which is easy to clean. Background Art

[0002] Laser cutting uses a high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature and evaporated to form holes. As the beam moves across the material, the holes continuously form very narrow cuts, completing the cutting of the material. Laser cutting requires the use of a laser cutting head.

[0003] Existing technology, such as patent number CN202321449975.3, discloses a laser cutting head, including a fiber laser mounting base, a collimator lens support frame cover, a collimator lens assembly support frame, an outer shell, a focusing lens protective cover, a high airflow nozzle support frame, a high airflow nozzle, a collimator lens, and a focusing lens. The collimator lens assembly support frame and the outer shell, the outer shell and the focusing lens protective cover, and the focusing lens protective cover and the high airflow nozzle support frame are all connected together by a bump and groove structure. This technical solution connects the collimator lens assembly support frame and the outer shell, the outer shell and the focusing lens protective cover, and the focusing lens protective cover and the high airflow nozzle support frame together by a bump and groove structure, reducing the problems of poor spot focusing effect and poor cutting quality caused by the large number of positioning parts and long dimensional chain caused by the above-mentioned pin positioning; the ratio between the support length L of the focusing lens mounting frame and the diameter D of the focusing lens is greater than or equal to 1.46, which helps to improve the up and down adjustment accuracy of the focusing lens assembly.

[0004] The disadvantage of the above-mentioned laser cutting head is that it is not convenient to quickly clean the cutting nozzle. Due to high-temperature cutting, cutting slag is generated in the cutting nozzle, which subsequently causes poor cutting and affects the cutting quality. Therefore, we designed a laser cutting head that is easy to clean. Summary of the Invention

[0005] The purpose of the present invention is to provide a laser cutting head that is easy to clean, so as to solve the problems raised in the above background technology.

[0006] The purpose of the present utility model can be achieved through the following technical solutions: a laser cutting head that is easy to clean, comprising a barrel-type reflector module, a focusing lens barrel, a cutting nozzle connecting part and a laser cutting nozzle, the bottom end of the barrel-type reflector module is threadedly assembled and connected to the focusing lens barrel, the bottom end of the focusing lens barrel is assembled with the cutting nozzle connecting part, the bottom end of the cutting nozzle connecting part is bolted and fastened to the laser cutting nozzle, the bottom side of the cutting nozzle connecting part is provided with a movable hinge, the bottom side of the cutting nozzle connecting part is provided with a cleaning cover through a movable hinge, the bottom of the inner cavity of the cleaning cover is provided with a rotating connecting platform, the bottom end of the rotating connecting platform is provided with a motor part connected to the cleaning cover, the top of the rotating connecting platform is provided with a hard cleaning seat connected to the inner cavity of the cleaning cover, and the middle part of the hard cleaning seat is provided with a cleaning cavity corresponding to the laser cutting nozzle.

[0008] In the above-mentioned easy-to-clean laser cutting head, both ends of the condensation pipeline extend to the outside of the cooling enclosure tube and are provided with flow cut-off valves, and a pipe bundle sleeve is provided at the condensation pipeline located outside the cooling enclosure tube.

[0009] In the aforementioned easy-to-clean laser cutting head, a mounting top plate is installed on the top of the cylindrical reflector module, and a mounting sleeve is provided on the top of the mounting top plate.

[0010] In the above-mentioned easy-to-clean laser cutting head, a locking rod is provided on the side thread of the mounting sleeve, one end of the locking rod passes through the interior of the mounting sleeve and the other end is connected to an adjusting handwheel.

[0011] In the aforementioned easy-to-clean laser cutting head, the diameter of the cleaning cover is equal to the diameter of the cutting nozzle connecting portion.

[0012] Compared with the prior art, the advantages of the laser cutting head of the present invention which is easy to clean are as follows: a cleaning cover is installed on the bottom side of the cutting nozzle connection part through a movable hinge, a rotating connecting platform is provided at the bottom of the inner cavity of the cleaning cover to connect the hard cleaning seat, and a motor component connected to the cleaning cover is provided at the bottom end of the rotating connecting platform, and the hard cleaning seat is driven to rotate by the rotation of the motor component.
