Technical Field

[0001] The utility model relates to the technical field of laser cladding heads, in particular to a rotary laser cladding head. Background Art

[0002] The laser cladding head is a key core component of the laser cladding system. It is used to connect the laser equipment with the powder feeder or wire feeder. The coating is quickly scanned by a high-energy laser beam, causing the prefabricated powder or wire to melt and solidify in an instant, forming a strong metallurgical bonding layer with the base metal, thereby significantly improving the hardness, wear resistance, corrosion resistance and other properties of the base metal.

[0003] The utility model with the authorization publication number CN221235660U provides a rotary laser cladding head, which belongs to the technical field of "laser cladding head" and the protected claim: "It includes a box body and a fixed box, a laser head is fixedly installed on the top of the box body, an adjustment mechanism is provided inside the fixed box, and a processing mechanism is provided at the bottom of the box body, the adjustment mechanism includes a rotating component and a rotation component, and the rotating component is arranged on the left side of the rotation component. The angle of the cladding head body is adjusted to change the cladding head body so that it is perpendicular to the part of the workpiece to be processed, so that the cladding head body is located at the center of the workpiece. It can also be used to adjust the laser emission direction of the cladding head body. The adjustment mechanism can be used to adjust the direction of the cladding head body in a variety of ways, and the scope of use is wider, so that the cladding head body can be rotated inside the workpiece, thereby increasing the processing range, eliminating the movement of the workpiece during processing, and preventing the cladding position from being unsatisfactory due to the movement of the workpiece, thereby improving the processing accuracy."

For this reason, we propose a rotating laser cladding head. Utility Model Content
