[0002] In the production and processing of hydraulic cylinder tie rods, laser marking machines are widely used to mark product information, model specifications, and other information on the surface of the tie rods. However, existing laser marking machines generate a large amount of fumes and dust when marking hydraulic cylinder tie rods.

[0036] After the collecting cylinder 10 is inserted into the U-shaped plate 8, the U-shaped plate 8 positions the collecting cylinder 10, and the magnetic force of the magnetic block 12 on the U-shaped plate 8 fixes the collecting cylinder 10 inside the U-shaped plate 8. After the collecting cylinder 10 is placed inside the U-shaped plate 8, the second vent 17 is connected to the first vent 6 through the collecting cylinder 10. The first vent 6 is located above the fan 5, and the second vent 17 is located between the inner cylinder 14 and the outer cylinder 9. When the fan 5 is started, the air inlet is opened by the fan 5.

[0040] The working principle of this utility model is as follows: First, according to the shape of the cylinder tie rod and the marking position, the cylinder 22 with the hollow elliptical cylinder 23 is fixed at the designated position by the cooperation of the bolt 21 and the threaded hole 20. Then, the cylinder tie rod can be positioned by the elliptical outline of the hollow elliptical cylinder 23.

[0041] Before marking, the hydraulic cylinder rod is placed on the placement plate 19, and the hollow elliptical cylinder 23 prevents the hydraulic cylinder rod from moving horizontally on the placement plate 19. Then, the hydraulic cylinder rod placed on the placement plate 19 is moved into the inner cylinder 14 by the fourth electric push rod 18. Then, the fiber optic marking device 3 is moved to the designated position by the cooperation of the first electric push rod 204, the second electric push rod 205 and the third electric push rod 209, and the fiber optic marking device 3 is used to laser mark the hydraulic cylinder rod.

[0042] During the marking process, the fan 5 is started, which draws the air in the inner cylinder 14 into the collection cylinder 10. Then, the dust and small particles in the flue gas are filtered through the filter screen 1102, and the harmful gases in the flue gas are absorbed through the activated carbon particles 1104. The filtered and purified air is discharged through the air outlet 7.

[0043] After marking is completed, the fiber optic marking device 3 is moved to the initial position by the cooperation of the first electric push rod 204, the second electric push rod 205 and the third electric push rod 209, and the hydraulic cylinder rod on the placement plate 19 is moved out of the inner cylinder 14 by the fourth electric push rod 18.

[0044] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
