The moving plate 5 provides a flexible moving platform, enabling the entire device to be easily moved to the position where marking is required. The laser head at the bottom of the laser marking machine 7 extends to the bottom of the L-shaped mounting plate 6. This design is to ensure that the laser marking machine can accurately align and contact the surface of large screws or studs for marking operations. Due to this extended design of the laser head, accurate positioning marking can be achieved regardless of the size of the screw or stud.

[0030] The implementation principle of the embodiment of the marking and positioning device for the surface of threaded elements in this application is as follows: First, the operator places one end of a larger screw or stud to be marked inside the three-jaw chuck 4 and clamps it to ensure its stability. Then, the operator starts the driving mechanism 22, and the motor 25 in the driving mechanism 22 starts to operate, driving the lead screw 24 to rotate. This rotation drives the arc-shaped limiting seat 20 to move through the threaded slider 23, so that the other end of the screw or stud can be smoothly inserted into the tapered positioning hole 21. This design ensures the precise positioning and stability of the screw or stud, providing convenience for subsequent operations;

[0031] At this time, the operator rotates the rotating shaft 15 to drive the second small gear 16 to rotate. Since the second small gear 16 is meshed and connected with the large gear 13, this rotation causes the large gear 13 to drive the first small gear 12 to start working. The meshing of the first small gear 12 and the rack 8 enables the moving plate 5 to move back and forth. This design simplifies the operation process, enabling the operator to easily control the position of the moving plate 5. At this time, the operator can accurately judge the position of the moving plate 5 by observing the position of the triangular indicator plate on the scale 18. This intuitive visual indication system ensures that the operator can accurately control the position of the laser marker 7, enabling it to accurately align with a specific part of the screw or stud for marking. The device can perform positioning and clamping according to the length of the screw or stud, and under the action of the operator controlling the forward and backward movement of the moving plate 5, perform precise marking operations through the laser marker 7. This design not only improves the accuracy and efficiency of marking, but also makes the operation process simpler and more convenient.
