Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a laser cutting machine which is easy to debug and has stable cutting. Background Art

[0002] Laser cutting machine is an advanced equipment that uses laser beam to cut materials. It has high cutting accuracy, fast speed and strong flexibility. The working principle of laser cutting machine is to generate a high-energy laser beam through a laser generator, which is focused by the optical path system and irradiated to the surface of the material to be cut, causing the material to melt, vaporize or burn instantly, thereby achieving cutting. With the continuous development of technology, the performance of laser cutting machines continues to improve, and the scope of application is becoming more and more extensive, providing strong support for the development of the manufacturing industry.

[0003] Prior art includes an invention patent with publication number CN115055839A, which discloses a laser cutting machine that is easy to debug and has stable cutting. The patent adopts a frame, a loading module and a laser module. The frame includes a loading frame and a laser frame. The laser frame is installed at the upper end of the rear side of the loading frame, the laser module is installed at the upper end of the laser frame, and the loading module is installed at the upper end of the loading frame; the laser module includes a laser module and a laser cutter head module, the laser cutter head module is installed at the front end of the laser module, the laser cutter head module is installed on the upper side of the loading frame, and a horizontal detection component is provided at the side end of the laser cutter head module; the loading module includes a loading drive module and a carrier module, the carrier module is installed at the upper end of the carrier module, a pin rack is provided in the middle of the carrier module, and the carrier module is evenly provided with clamp fixing components along the outer edge of the pin rack. The present invention has high cutting accuracy, uniform cutting seam, stable cutting and good cutting model, and the laser cutter head module can be easily debugged to improve efficiency, thereby solving the problem that the focusing mirror of the laser cutting machine often needs to be replaced during debugging and use. The focusing mirror of the existing laser cutting machine is often installed inside the cutting head, and it often takes a long time to replace the focusing mirror. In addition, during the debugging process, replacing the focusing mirror once may not achieve the best focusing effect, thus affecting the processing production efficiency.

[0004] In the process of using laser cutting machines to produce and process workpieces, most of the manually adjusted laser cutting machines on the market need to rotate two or three limit screws during adjustment. After the screws are loosened, adjust the height of the focusing lens. After the adjustment is completed, tighten the limit screws to re-limit the focusing lens. Since the operation of the manually adjusted laser cutting machine is relatively cumbersome, the debugging efficiency will be limited by the operating steps when the staff is performing the debugging operation, and the debugging operation of the equipment is inconvenient. Utility Model Content

By setting the auxiliary component, it is convenient for the staff to debug the laser cutting machine, thereby reducing the cumbersome operation of the existing manual debugging, the problem of inconvenience in debugging the equipment, and further improving the convenience and efficiency of equipment debugging.
