DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-2 An embodiment of the present invention provides a manually focusable rotating laser head device for internal hole texturing, comprising a rotating motor assembly and a rotating mirror base connected thereto, wherein the rotating mirror base is fixed to the rotating motor assembly by a locking screw, a focusing mirror assembly is provided in the rotating mirror base, an inclined surface is provided on the upper portion of one end of the rotating mirror base away from the rotating motor assembly, a reflective mirror assembly is provided on the upper cover of the inclined surface, and a protective mirror assembly is provided on the bottom of the end of the rotating mirror base provided with the inclined surface.

[0027] The rotating motor assembly is a direct-drive motor. The direct-drive motor and the rotating mirror mount are sealed with a sealing ring. The focusing lens assembly includes a focusing sleeve, an adjustment ring, and a focusing lens. The focusing sleeve is mounted within the rotating mirror mount, and the adjustment ring and focusing lens are installed within the focusing sleeve. The focusing lens is secured to the adjustment ring via a locking nut. Sealing rings are provided at opposite ends of the focusing sleeve, each containing a sealing ring. A limiting groove is defined in the middle of the focusing sleeve. An adjustment knob is provided on the upper portion of the rotating mirror mount, and a cam is provided at the lower end of the adjustment knob, which is located within the limiting groove. When the adjustment knob is rotated, the focusing sleeve is driven to move forward and backward along the axis of the rotating mirror mount for adjustment. A sealing ring is installed in the middle of the adjustment knob to prevent dust. A graduated ring is mounted on the rotating mirror mount via a locking screw. The inner edge of the graduated ring presses against the adjustment knob, and the graduated ring has scale marks on its surface, indicating the adjustment status. Once the focusing lens position is adjusted, the focusing lens sleeve can be secured with a set screw.

[0028] The reflector assembly consists of a reflector, a spring, and a cover. The reflector and spring are mounted within the cover, which is connected to the mirror base via locking screw (3) and a locating pin. The spring is cylindrical. The cover has two threaded holes with set screws inserted into them. Adjusting the set screws' feed through the threads compresses the lever adjustment block. A counterweight is also mounted on the cover via locking screw (4) to maintain dynamic balancing during the rotation of the direct-drive motor.

[0029] A sealing ring (four) connects the protective mirror assembly to the rotating mirror mount. The clamping block is connected to the mirror mount via locking screw (five). The protective mirror and rotating mirror mount are connected via locking nut (two). The connecting block and the clamping block are connected via locking screw (six). The texturing nozzle and the connecting block are threaded. Light reflected from the reflector exits the texturing nozzle and irradiates the inner wall of the pipe. Cooling gas is also ejected from the texturing nozzle, protecting the laser head. For different pipe inner diameters, after adjusting the focusing lens position, replace the corresponding connecting block and counterweight to maintain dynamic balancing.

[0030] A groove is provided on the inclined surface, and two small grooves are provided on the groove. A lever adjustment block is installed in the small groove. Two shaft holes are provided on both sides of the inclined surface of the rotating mirror seat. A shaft hole is provided in the shaft hole. The middle of the lever adjustment block is fixed by the shaft, and the two ends of the lever adjustment block can rotate around the shaft in the small groove. A protruding ball is provided at one end of the lever adjustment block, and a protruding ball is also fixed in the groove. An isosceles triangle is formed between the three balls with the ball in the groove as the vertex. By adjusting the feed amount of the top screw, one end of the lever adjustment block is pressed so that the ball at the other end of the lever adjustment block contacts the reflector. Under the action of the cylindrical spring elastic force, a lever mechanism is formed, thereby achieving the adjustment of the reflector angle. An isosceles triangle is formed between the three balls with the ball in the groove as the vertex, so that the adjustment amplitude of the lever adjustment blocks on both sides is the same, which is more convenient for adjusting the reflector angle.

[0031] An annular heat dissipation groove is provided on the outer surface of the rotating mirror holder. Since a certain amount of heat is generated during the laser texturing process and the lens may be damaged, the annular heat dissipation groove is used to remove the heat when the direct drive motor drives the rotating mirror holder to rotate, so as to protect the laser head.

[0032] This device adjusts the focal length by adjusting the knob and replacing the adjustment rings of different lengths. It can adapt to the laser texturing processing of pipes with different inner diameters. It has a large adjustment range and high cost savings. It can accurately adjust the position of the reflector. Under the condition of fixing the pipe, the laser texturing head can be rotated 360 degrees to achieve the purpose of rapid processing.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
