[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-3 This utility model provides an embodiment of a laser engraving machine with a multi-axis adjustment mechanism, including an operating frame 1 and a mounting frame 2. The mounting frame 2 is slidably connected to the inner front wall of the operating frame 1. A transverse moving component 3 is fixedly installed on the outer side wall of the operating frame 1, and a lifting component 4 is fixedly installed on the inner bottom wall of the operating frame 1. An adjustment mechanism 5 is provided on the mounting frame 2, and an auxiliary mechanism 6 is provided on the adjustment mechanism 5. The adjustment mechanism 5 includes a rotator 51, which obtains stable support through a fixed connection with the mounting frame 2 and provides power for the rotation of the movable cylinder 52. It is the key power source for adjusting the orientation of the engraving machine head body 56. The rotator 51 is fixedly connected to the outer front wall of the mounting frame 2, and the output end of the rotator 51 is connected to... A movable cylinder 52 is fixedly connected via a coupling. A drive motor 53 is fixedly connected to the left outer wall of the movable cylinder 52. An annular groove 54 is formed on the top inner wall of the movable cylinder 52. An annular frame 55 is slidably connected to the left and right inner walls of the annular groove 54. A carving machine head body 56 is fixedly connected to the right outer wall of the annular frame 55. A rotating rod 57 is fixedly connected to the output end of the movable cylinder 52 via a coupling. A spur gear 58 is fixedly connected to the side outer wall of the rotating rod 57. The spur gear 58 rotates synchronously with the rotating rod 57. Through meshing with the tooth groove 59, the rotational power of the rotating rod 57 is converted into the moving force of the annular frame 55. It is a key transmission component for adjusting the rotation direction of the carving machine head body 56. The annular frame 55 has a tooth groove 59 formed on the side outer wall.

[0024] Reference Figures 2-4 The output end of the lifting component 4 is fixedly connected to the bottom outer wall of the mounting frame 2. The fixed connection between the output end of the lifting component 4 and the bottom outer wall of the mounting frame 2 allows the lifting power of the lifting component 4 to be directly transmitted to the mounting frame 2. The movable cylinder 52 is rotatably connected to the front outer wall of the rotator 51. The annular groove 54 penetrates the bottom outer wall of the movable cylinder 52. The rotating rod 57 is rotatably connected to the right inner wall of the movable cylinder 52 through the bearing. The tooth groove 59 contacts the side outer wall of the spur gear 58. The close contact between the tooth groove 59 and the side outer wall of the spur gear 58 ensures the reliability of the meshing transmission between the two and avoids slippage during transmission. There are several tooth grooves 59, and several tooth grooves 59 are opened in a ring on the side outer wall of the annular frame 55.

[0025] Reference Figures 3-4The auxiliary mechanism 6 includes a shaft disk 61, which is fixedly connected to the output end of the rotary device 51. A threaded rod 62 is threadedly connected to the inner rear wall of the shaft disk 61. The threaded rod 62 is threaded to the inner rear wall of the shaft disk 61, and the threaded connection between the threaded rod 62 and the mating plate 64 can be achieved by rotation. This is a key component for controlling the fixing or disassembly of the movable cylinder 52. An adjusting plate 63 is fixedly connected to the outer rear wall of the movable cylinder 52, and a mating plate 64 is fixedly connected to the outer rear wall of the adjusting plate 63. The fixed connection between the mating plate 64 and the adjusting plate 63 provides a locking mating point for the threaded rod 62. 2. The threaded engagement with the mating plate 64 secures the shaft disc 61 and the adjusting disc 63. A positioning rod 65 is fixedly connected to the rear outer wall of the adjusting disc 63. The movable cylinder 52 contacts the front outer wall of the shaft disc 61. The adjusting disc 63 is fixedly connected to the rear outer wall of the movable cylinder 52. The threaded rod 62 is threadedly connected to the rear inner wall of the mating plate 64. A steel sleeve is fixedly connected to the side outer wall of the positioning rod 65. The steel sleeve on the side outer wall of the positioning rod 65 can enhance the structural strength and wear resistance of the positioning rod 65 and reduce the frictional loss between the positioning rod 65 and the inner wall of the shaft disc 61. The positioning rod 65 penetrates the front inner wall of the shaft disc 61.

[0026] Working principle: By activating the lateral movement component 3, the operating frame 1 is moved laterally for adjustment. By activating the lifting component 4, the mounting frame 2 is adjusted vertically. By activating the rotator 51, the movable cylinder 52 is rotated, which in turn rotates the ring frame 55. The ring frame 55 then adjusts the orientation of the engraving machine head body 56. Subsequently, the drive motor 53 is activated, causing the rotating rod 57 to rotate. The rotating rod 57 then rotates the spur gear 58, which in turn moves the tooth groove 59. The tooth groove 59 then moves the ring frame 55, which adjusts the rotation direction of the engraving machine head body 56. This allows the engraving machine head body 56 to rotate and be adjusted in multiple axes and directions, facilitating the engraving of items with different curved shapes. For long-term use, rotating the adjustment disc 63 separates the threaded rod 62 from the docking plate 64, and then pulling the adjustment disc 63 separates it from the shaft disc 61, allowing for easy disassembly of the movable cylinder 52. This facilitates convenient disassembly, maintenance, or replacement of the adjustment mechanism 5.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
