However, when the above-mentioned laser tube cutting machine transmits the steel pipe to the chuck, due to the misalignment between the steel pipe and the chuck, the steel pipe cannot be smoothly chucked into the chuck, thereby affecting the cutting. Utility Model Content

[0004] The utility model provides an adjusting device for a laser pipe cutting machine, which can adjust the position of a steel pipe so that the steel pipe is aligned with a bayonet of a chuck.

[0005] The technical solution adopted by the utility model to solve the above technical problems is: an adjustment device of a laser tube cutting machine, including a frame, a plurality of conveying rollers fixed on the frame and a chuck fixedly connected to the frame, characterized in that the frame is slidably connected to a mounting frame on one side of the chuck, an adjusting member is fixedly connected to the mounting frame, a through hole is opened in the adjusting member, the diameter of the through hole close to the chuck end gradually increases toward the end away from the chuck, the through hole close to the chuck end is opposite to the chuck mouth, when the steel pipe is conveyed, the steel pipe passes through the through hole and is opposite to the chuck mouth, and a protective pad is fixedly connected to the inner wall of the through hole.

[0023] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0025] Figure 1-Figure 6As shown, the adjusting device of the laser tube cutting machine includes a frame 1, a plurality of conveying rollers 2 fixed on the frame 1, and a chuck 12 fixedly connected to the frame 1. When cutting a steel pipe, the steel pipe is located on the plurality of conveying rollers 2. At this time, the conveying rollers 2 rotate and drive the steel pipe to move forward, so that the steel pipe enters the bayonet of the chuck 12 for easy cutting. The frame 1 is fixedly connected with a mounting frame 9 on one side of the chuck 12. An adjusting member is slidably connected to the mounting frame 9. A through hole 11 is opened in the adjusting member. The diameter of the through hole 11 at one end close to the chuck 12 gradually increases toward the end away from the chuck 12. The end of the through hole 11 close to the chuck 12 and the bayonet of the chuck 12 are connected. Relatively speaking, when the conveying roller 2 conveys the steel pipe to the adjusting member, the steel pipe enters the through hole 11 through the end with the largest diameter of the through hole 11, and gradually aligns with the bayonet position of the chuck 12 along the direction of the through hole 11 until the steel pipe passes through the through hole 11. At this time, the steel pipe is aligned with the bayonet position of the chuck 12. At this time, the mounting frame 9 slides toward the side close to the chuck 12, so that the end of the steel pipe passing through the through hole 11 smoothly enters the bayonet position of the chuck 12, thereby facilitating the subsequent cutting of the steel pipe. At this time, the adjusting member plays a role in adjusting the position of the steel pipe, so that the steel pipe is aligned with the bayonet position of the chuck 12 during the conveying process, which facilitates the steel pipe to enter the chuck 12.

[0026] Figure 2-Figure 6 As shown, the adjusting member includes a guide ring 3 and a plurality of adjusting plates 4 fixedly connected to one end of the guide ring 3 near the chuck 12. The plurality of adjusting plates 4 are arranged in a ring with the center of the guide ring 3 as the center. There is a gap 5 between two adjacent adjusting plates 4, and the adjusting plates 4 are elastic. Therefore, when cutting steel pipes of different sizes, as the steel pipe passes through, the plurality of adjusting plates 4 are deformed due to the force of the steel pipe, and when the adjusting plates 4 are deformed, the gap 5 between two adjacent adjusting plates 4 becomes larger or smaller, so that the minimum diameter of the through hole 11 is changed according to the size of the steel pipe, so that the steel pipe can pass through the through hole 11 smoothly. This design enables the minimum diameter of the through hole 11 to be adjusted according to actual needs, so that the adjusting member can be suitable for steel pipes of different sizes, thereby improving the practicality of the adjusting member.

[0027] Figure 2-Figure 6 As shown, a set of adjusting rings 6 arranged outside the adjusting pieces 4 are slidably connected to the mounting frame 9, so when the light tube passes through the through hole 11, the adjusting ring 6 slides and is sleeved outside a number of adjusting pieces 4 during the sliding process. As the adjusting ring 6 gradually slides away from the end of the chuck 12, the gaps 5 between the several adjusting pieces 4 gradually decrease, so that the adjusting pieces 4 are in contact with the surface of the steel pipe, thereby fixing the steel pipe. This design plays a role in fixing the steel pipe in the adjusting member.

[0028] Figure 2-Figure 6As shown, the adjusting ring 6 is slidably connected to the mounting frame 9 through the fixing rod 7. The mounting frame 9 is provided with a slide groove 10 for facilitating the sliding of the fixing rod 7. The mounting frame 9 is fixedly connected with a cylinder 8. The telescopic rod of the cylinder 8 is fixedly connected to the fixing rod 7. When the adjusting ring 6 needs to slide, the cylinder 8 is started. At this time, the lifting and retracting rod of the cylinder 8 pushes the fixing rod 7 to slide away from the end of the chuck 12. At this time, the fixing rod 7 slides in the slide groove 10, and the adjusting ring 6 also slides accordingly, thereby tightening a number of adjusting sheets 4. This design facilitates the sliding of the adjusting ring 6.

[0029] Figure 2-Figure 6 As shown, the inner wall of the adjusting plate 4 is located at one end of the protective pad 14 close to the guide ring 3 and is fixedly connected with a sensing element 13. When the sensing element 13 abuts against the steel pipe, the cylinder 8 stops. Therefore, when the adjusting ring 6 slides, the gap 5 between the adjusting plates 4 gradually decreases as the adjusting ring 6 slides, until the sensing element 13 on the adjusting plate 4 abuts against the steel pipe. At this time, the sensing element 13 transmits a command to the cylinder 8 to stop pushing the flagpole. At this time, the adjusting ring 6 stops sliding, and the adjusting plate 4 just clamps the steel pipe. This design plays a role in controlling the sliding position of the adjusting ring 6, thereby ensuring that the adjusting plate 4 can fix steel pipes of different sizes.

[0030] Figure 2-Figure 6 As shown, a protective pad 14 is fixedly connected to the inner wall of the adjusting piece 4, and the protective pad 14 is elastic. When the protective pad 14 forms abutment with the steel pipe, the protective pad 14 is deformed, and the friction force of the protective pad 14 close to the side wall of the steel pipe is greater than the friction force at both ends of the protective pad 14. By providing the protective pad 14, the surface of the steel pipe can be protected when the adjusting piece 4 forms abutment with the steel pipe, thereby preventing the adjusting piece 4 from scratching the surface of the steel pipe or causing dents on the surface of the steel pipe during the process of fixing the steel pipe. At the same time, the protective pad 14 can increase the friction between the steel pipe and the adjusting piece 4, thereby making the fixing of the adjusting piece 4 to the steel pipe more firmly.

[0031] The above is an introduction to the adjustment device of the laser tube cutting machine provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the utility model and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
