Description

Technical Field

[0001] The present invention relates to the technical field related to laser texturing of pipeline inner walls, and in particular to an inner hole texturing laser head device with an adjustable reflector. Background Art

[0002] Laser texturing is a new and emerging technology for texturing cold-rolled steel rolls. Laser-textured rolls have a longer service life than shot-peened rolls. During the plate rolling process, they can increase rolling speeds, reduce surface scratches, improve plate shape, and prevent sticking during coil annealing, significantly improving factory productivity and product quality.

[0003] In the bore roughening laser head, a reflector is used to reflect light to change its direction and act on the inner wall of the pipe. In actual application, due to machining errors and assembly errors, the inclination angle of the assembled reflector may be inconsistent with the theoretical reflector inclination angle, causing the reflection angle of the light reflected by the reflector to be different from the theoretical reflection angle. This leads to a deviation between the light path reflected by the reflector and the theoretical reflection light path, reducing the light utilization efficiency and possibly preventing the optical fiber from being emitted, resulting in the inability to process. Therefore, after assembly, the inclination angle of the reflector needs to be adjusted so that the actual inclination angle of the reflector is the same as the preset inclination angle.
