[0055] Example 1:

[0056] Please see Figures 1-2 This utility model discloses a laser-based marking device, comprising a fixed base 1, an electromagnetic chuck 2 fixedly connected to the lower end face of the fixed base 1, a mounting shaft 3 fixedly connected to the center of the upper end face of the fixed base 1, a mounting slider 4 slidably connected to the outer side of the mounting shaft 3, a mounting rod 5 fixedly connected to the right side of the mounting slider 4, a U-shaped mounting block 6 slidably connected to the outer side of the mounting rod 5, a laser head 7 rotatably connected to the left, right, and lower end faces of the U-shaped mounting block 6, a rotating handle 8 rotatably connected to the right side of the mounting slider 4 via a circular plate, and a connecting rod 9 rotatably connected to the right side of the mounting slider 4, wherein the connecting rod 9 is fixedly connected to the rotating handle 8 via the circular plate.

[0057] The working principle of a laser-based scribing device based on Embodiment 1 is as follows:

[0058] First, before use, place the device at the location on the hull where the marking operation is to be performed, and then turn on the electromagnetic chuck 2 to securely connect the device to the hull.

[0059] Second, after turning on the laser head 7, hold the laser head 7 and rotate it to adjust the initial position of the laser irradiation line. As needed, turn on the electric push rod 16 to control the steel needle 29 to move to the irradiation position of the laser head 7.

[0060] Third, manually hold the handle 8 and rotate it forward (or backward) as needed to move the mounting slider 4 and adjust the height of the mounting rod 5. After completion, hold the mounting rod 5 and rotate it relative to the mounting shaft 3 to perform the marking.

[0061] Example 2:

[0062] Please see Figures 2-6 The laser-based line-drawing device of this utility model, compared with Embodiment 1, further includes:

[0063] A worm gear 10 is fixedly connected to the left end face of the connecting rod 9. A worm wheel 11 is meshed with the lower end of the worm gear 10. A groove 12 is provided around the outer side of the mounting shaft 3, and the groove 12 meshes with the left side of the worm wheel 11. A cross groove 13 is provided at the right end of the mounting rod 5. A first rectangular frame 14 is fixedly connected inside the left end of the mounting rod 5. A C-shaped plate 15 is connected to the right end of the first rectangular frame 14. An electric push rod 16 is fixedly connected to the center of the left end face of the inner side of the first rectangular frame 14, and the output end of the electric push rod 16 is fixedly connected to the left end face of the outer side of the C-shaped plate 15. The first rectangular frame 14 and the C-shaped plate 15 are placed perpendicular to each other. The right end of the frame 14 has a slot 17, and the leftmost end of the telescopic plate 18 is rotatably connected to the slot 17. The telescopic plate 18 is composed of multiple connecting plates that are rotatably connected in a cross pattern. The leftmost end of the telescopic plate 18 has a first node 19. The right side of the first node 19 on the left side of the telescopic plate 18 has a second node 20, and the second node 20 is rotatably connected to the right end of the inner side of the C-shaped plate 15. The rightmost end of the telescopic plate 18 has a third node 21, and the left end of the connecting column 22 is rotatably connected to the third node 21 on the right side of the telescopic plate 18. The lower end face of the connecting column 22 is fixedly connected to a bolt 23, and the bolt 23 passes through the cross groove 13 and slides with the cross groove 13.

[0064] A nut 24 is threaded through the bolt 23. A connecting block 25 is rotatably connected to the right end face of the connecting column 22. Limiting plates 26 are fixedly connected to the left and right sides of the connecting block 25, and the limiting plates 26 are slidably connected to the cross groove 13 inside the cross groove 13. A sliding groove 27 is provided on the outer side of the connecting block 25. A connecting plate 28 is slidably connected to the inner side of the sliding groove 27. A steel needle 29 is inserted and tightly connected to the lower end face of the connecting plate 28. A rubber pad is provided at the insertion and tight connection between the connecting plate 28 and the steel needle 29 to increase friction and prevent the steel needle 29 from slipping out. A rotating shaft 30 is rotatably connected inside the connecting block 25. The outer arc surface of the rotating shaft 30 Multiple elastic rubber protrusions 31 are fixedly connected, and multiple rubber blocks 32 are fixedly connected to the left end face of the connecting plate 28. The left end face of the connecting plate 28 is an arc surface, and the rubber blocks 32 are located inside the arc surface. The elastic rubber protrusions 31 and the rubber blocks 32 are interlocked and connected. When the connecting plate 28 moves, the friction and repeated interlocking between the elastic rubber protrusions 31 and the rubber blocks 32 can make the connecting plate 28 relatively positioned and adjusted to prevent automatic sliding. The center of the left and right sides of the rotating shaft 30 is rotatably connected to the connecting short plate 33, and the end of the connecting short plate 33 away from the rotating shaft 30 is rotatably connected to the connecting plate 28.

[0065] The working principle of this embodiment is as follows:

[0066] First, when the electric push rod 16 is turned on, it pushes the C-shaped plate 15, which in turn moves the second node 20 on the telescopic plate 18. At the same time, it is relatively limited by the connection between the first node 19 and the slot 17. At this time, the first rectangular frame 14 is stationary. When the second node 20 moves, it will relatively drive the telescopic plate 18 to extend and retract. Through the rotational connection with the connecting column 22, it drives the connecting block 25 and the limiting plate 26 to slide inside the cross groove 13, thereby driving the connecting plate 28 and the steel needle 29 to the laser head 7 irradiation position.

[0067] Secondly, when it is necessary to mark lines at different positions, the electric push rod 16 is turned on to drive the telescopic plate 18 to extend and retract, while the connecting block 25 is moved out of the cross groove 13. Then, the connecting block 25 is manually held and rotated to the left or right. After adjusting according to the needs, the electric push rod 16 is turned on again to drive the telescopic plate 18 to extend and retract, and the connecting block 25 is moved back to the inside of the cross groove 13. This makes it more convenient to use. In addition, if some special situations are encountered (such as some difficult-to-mark planes), the nut 24 is turned on and tightened along the bolt 23. The connecting block 25 can also be fixed again by the connecting column 22, which can also effectively prevent loosening during marking.

[0068] Third, when adjusting the height, simply turn the handle 8 manually. This will drive the worm gear 10 to rotate via the connecting rod 9. Simultaneously, the worm wheel 11 will rotate, and the mounting slider 4 will move upward or downward via the groove 12. This allows for adjustment. When scribing lines, by holding the mounting rod 5 and rotating the mounting slider 4 along the mounting shaft 3, the worm wheel 11 will mesh with the groove 12. At the same time, the teeth on the worm wheel 11 will slide against the groove 12, thus achieving scribing by rotation.

[0069] This utility model provides an improved laser-based marking device. In use, the electric push rod 16 is activated to move the C-shaped plate 15. Simultaneously, the first node 19 limits the movement of the second node 20, causing the telescopic plate 18 to extend and retract. At the same time, the steel needle 29 can also be moved to achieve adjustment. When it is necessary to adjust the marking direction, the electric push rod 16 is activated to extend and retract the telescopic plate 18, pushing the connecting block 25 out of the cross groove 13. Then, rotating the connecting block 25 can also quickly adjust the marking direction. When adjusting the height, only the rotating handle 8 needs to be rotated to achieve the same result quickly. No multiple steps are required, making it more convenient and simple to use.
