[0017] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described clearly and completely below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments derived by persons of ordinary skill in the art without inventive effort are also within the scope of protection of the present invention.

[0018] The specific implementation of the present invention will be described below with reference to the accompanying drawings:

[0019] like Figures 1 to 3As shown, a laser marking device includes a workbench 1, a laser marking machine 2, a height adjustment mechanism 3, and a transverse clamping mechanism 4. The workbench 1 is provided with the height adjustment mechanism 3, and the laser marking machine 2 is connected to the workbench 1 via the height adjustment mechanism 3. The height adjustment mechanism 3 allows the laser marking machine 2 to be freely adjusted in height, thereby maintaining a stable marking effect. A transverse clamping mechanism 4 is provided directly below the laser marking machine 2 and is fixedly connected to the workbench 1. The transverse clamping mechanism 4 provides a stable clamping of the steel bars, preventing them from vibrating during the marking process and affecting the marking effect.

[0020] The transverse clamping mechanism 4 includes a clamping assembly 5, a bidirectional screw rod 43 and a transverse motor 41. The clamping assembly 5 is slidably connected to the workbench 1. The two ends of the bidirectional screw rod 43 are provided with a clamping assembly 5, and the clamping assembly 5 is provided with a threaded hole 512 that matches the bidirectional screw rod 43. One end of the bidirectional screw rod 43 is fixedly connected to the output end of the transverse motor 41. The transverse motor 41 drives the bidirectional screw rod 43 to rotate, so that the clamping assemblies 5 on both sides move in opposite directions to achieve clamping or loosening of the steel bar sample. A guide rail 42 that matches the clamping assembly 5 is provided on the workbench 1, and a limit block 421 is provided at both ends of the guide rail 42. One end of the bidirectional screw rod 43 is rotatably connected to the limit block 421, and the other end passes through the limit block 421 and is connected to the transverse motor 41. The clamping assembly 5 moves along the length direction of the guide rail 42. The clamping assembly 5 includes a slider 51 and a top plate 52. The top of the slider 51 is provided with a V-shaped notch 511. The V-shaped mouth 511 can stably accommodate steel bar samples of various sizes and prevent the steel bar samples from rolling on the plane. An elastically connected top plate 52 is provided on one side of the slider 51. A plurality of guide rods 513 are provided on the side of the slider 51 close to the top plate 52. One end of the guide rod 513 is integrated with the slider 51, and the other end is fixedly connected by a limit plate 515. A rough surface 521 is provided on the side of the top plate 52 close to the slider 51. The guide rod 513 passes through the top plate 52, and a spring 514 is provided on the circumference of the guide rod 513. One end of the spring 514 is in contact with the top plate 52, and the other end is in contact with the limit plate 515. Under the action of the spring 514, the rough surface 521 of the top plate 52 is tightly fitted with the end face of the steel bar sample to prevent the steel bar sample from rotating.

[0021] The height adjustment mechanism 3 is equipped with a height scale 31. This scale 31 quantifies changes in the height of the laser marker 2, enabling precise height control. The height adjustment mechanism 3 includes a lift motor 32 and a screw. The screw is vertically mounted, with its upper end fixedly connected to the output of the lift motor 32. The laser marker 2 is equipped with a connecting rod 21, which is threadedly connected to the screw. The lift motor 32 controls the forward and reverse rotation of the screw, thereby enabling the connecting rod 21 to move the laser marker 2 up and down.

[0022] During the marking process, the laser marking machine 2 will emit a dazzling bright light and a harsh noise. A hinged barrier assembly 11 is provided on the workbench 1, and the barrier assembly 11 is located on the side of the transverse clamping mechanism 4 close to the operator. The barrier assembly 11 is connected to the workbench 1 through a hinge at the bottom. Guard plates 112 are provided on both sides of the barrier assembly 11, and a brown soundproof transparent plate 111 is provided on the front. The guard plates 112 can reduce the spread of noise from the sides of the equipment, and the brown soundproof transparent plate 111 can reduce light pollution and the spread of noise on the front of the equipment. After installing the steel bar assembly on the transverse clamping mechanism 4, flip up the barrier assembly 11, and use the barrier assembly 11 to reduce the impact of light pollution and sound pollution on the operator.

[0023] The working principle of this embodiment of the utility model is as follows: a steel bar sample is placed on the V-shaped notch 511 of the slider 51, and the transverse motor 41 is activated to move the clamping assemblies 5 on both sides toward the middle. At this time, the top plate 52 clamps the end face of the steel bar sample to prevent the steel bar sample from deflecting during the proofing process.
