[0002] A laser engraving machine is a device that can mark the surface of various materials. Its principle is to use the high temperature generated by the laser beam to cause different degrees of ablation on the surface of the material to achieve the purpose of leaving a mark.

[0003] Authorization publication number "CN214558398U" records that a laser engraving machine with a fixed structure includes a base, a mounting box is fixedly mounted on the top of the base, a frame is fixedly mounted on the top of the base, a laser head is movably mounted on the frame of the frame, a workbench is fixedly mounted on the top of the mounting box, a rotating rod is rotatably connected to the bottom of the workbench, a positive thread screw is fixedly connected to the left side of the rotating rod, and a reverse thread screw is fixedly connected to the right side of the rotating rod. By setting a positive thread screw and a reverse thread screw with opposite thread directions, the first clamping mechanism and the second clamping mechanism can be clamped or separated when the rotating rod is rotated, so that the engraving workpiece can be clamped or loosened, so as to prevent the movement of the workpiece during the engraving process from causing engraving failure. At the same time, because the first clamping mechanism and the second clamping mechanism are symmetrically arranged on both sides of the workbench, the workpiece can be clamped at the center of the workbench, which is convenient for engraving operations.

[0004] The above patent sets a positive thread screw and a reverse thread screw with opposite thread directions. When the rotating rod is rotated, the first clamping mechanism and the second clamping mechanism can be clamped or separated, so that the engraving workpiece can be clamped or loosened, thereby preventing the movement of the workpiece during the engraving process from causing engraving failure.

[0033] In a specific embodiment of the utility model, the bottom plate 1 serves as the supporting base of the entire engraving machine, bears the weight of the entire device, and maintains the stability of the device. The side plate 2 is connected to the side end of the bottom plate 1 to provide lateral support and stability for the device, and may also be used to isolate or protect the internal mechanism. The placement plate 3 is fixedly connected to the upper end of the side plate 2, and is used to place the objects to be engraved, providing a stable platform for the processing object. The clamping mechanism includes a plurality of components, which work together to achieve the fixation and stability of the object to be engraved, prevent movement or shaking during the engraving process, and ensure the accuracy and quality of the engraving. The frame 10 is fixedly connected to the upper end of the placement plate 3 to provide the main supporting structure for the clamping mechanism. The light rod 11 is fixedly connected to the side end of the frame 10, and may be used to guide the light emitted by the laser generator to ensure that the laser can be accurately focused on the engraving position. The first connecting rod 12: It is rotatably connected to the placement plate 3, as part of the clamping mechanism, and the movement of the clamping plate is achieved by rotation. The second connecting rod 13 is rotatably connected to the side end of the first connecting rod 12, further expanding the range of motion of the clamping mechanism or increasing the clamping force. The clamping plate 14 is slidably connected to the light rod 11, and is rotatably connected to the second connecting rod 13 to clamp and fix the object to be engraved. The driving component is arranged at the side end of the frame 10, and is used to drive the movement of the clamping plate 14 to adjust the clamping force and position, or to realize the automatic opening and closing of the clamping mechanism.

[0034] For details, please refer to Figure 2-Figure 4 The driving assembly includes a mounting plate 16 and a cylinder 17 . The mounting plate 16 is fixedly connected to the side end of the frame 10 . The cylinder 17 is fixedly connected to the side end of the mounting plate 16 .

[0035] In this embodiment: the mounting plate 16 is fixedly connected to the side end of the frame 10, providing a platform for installing and fixing the cylinder 17. The setting of the mounting plate 16 can increase the stability of the cylinder 17 and facilitate the maintenance and replacement of the entire drive assembly. The cylinder 17 is fixedly connected to the side end of the mounting plate 16 and is an actuator that drives the clamping plate 14 to move. The cylinder 17 generates power through the pressure change of compressed air or hydraulic oil, thereby pushing the clamping plate 14 to move back and forth, and realizing the clamping and loosening of the object to be engraved. The output end of the cylinder 17 is connected to the clamping plate 14, and this connection method can be a mechanical connection, such as a threaded connection, a pin connection, etc., or other types of connections, such as an electromagnet connection, etc. When the cylinder 17 receives a signal and acts, the power is transmitted to the clamping plate 14 through the connection of the output end, thereby realizing the opening and closing action of the clamping plate 14. The function of the drive assembly is to enable the clamping plate 14 to be quickly and accurately adjusted in position as needed, so as to facilitate the placement and fixing of the object to be engraved, and improve the efficiency and accuracy of engraving.
