[0002] In the field of modern pipe processing, laser pipe cutting machines have been widely used due to their significant advantages, such as high cutting speed, high precision, good cut quality, and ability to process complex shapes. When operating a laser pipe cutting machine, a chuck mechanism is needed to stably and reliably clamp and position the pipe, ensuring that the pipe is accurately positioned during the cutting process without shaking or displacement, thus guaranteeing that the cutting operation can be completed efficiently and precisely.

[0003] In existing technologies, common chuck mechanisms can only achieve clamping in one direction.

This not only leads to deviations in the cutting position of the tube but also affects the cutting accuracy. How to invent a chuck mechanism for laser tube cutting machines to solve these problems has become an urgent issue for those skilled in the art. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Example, refer to Figures 1-6 A chuck mechanism for a laser tube cutting machine includes a base 1 and a chuck assembly 4 mounted on the base 1. Symmetrical slide rails 11 are provided on the inner sidewall of the base 1. A first cylinder 18 is installed on the inner sidewall of the base 1 near the two slide rails 11. A bracket 12 is provided at the upper end of the base 1. A first slide groove 13 is opened on the inner sidewall of the base 1 near the slide rails 11. A first lead screw 14 is installed on the inner wall of the first slide groove 13. A first motor 15 and an ear plate 16 are installed at one end of the base 1 near the first slide groove 13. A guide rod 17 is installed at one end of the ear plate 16. A cutting assembly is also installed on the base 1. The chuck assembly 4 is installed below the bracket 12, and the chuck assembly 4 positions the pipe. The cutting assembly is installed in the first chute 13 and cuts the pipe. Furthermore; the two ends of the first lead screw 14 are rotatably connected to the inner wall of the first slide groove 13, the output end of the first motor 15 is fixedly connected to one end of the first lead screw 14, the two ends of the guide rod 17 are respectively fixedly connected to the ear plate 16 and one end of the bracket 12, the chuck assembly 4 includes a fixed frame 41, a slide 42, a support frame 43, a third motor 44, a gear 45, a clamping frame 46, a second cylinder 47, a clamping block 48 and a roller 49, the side wall of the fixed frame 41 is fixedly connected to the side wall of the slide 42, the slide 42 is slidably connected to the slide rail 11, a fixed plate 421 is fixedly connected to one end of the slide 42, one end of the fixed plate 421 is fixedly connected to the telescopic end of the first cylinder 18, the support frame 43 is set inside the fixed frame 41, the third motor 44 is installed on the upper end of the fixed frame 41, and the gear 45 is fixedly connected to the upper end of the fixed frame 41. One end of 5 is rotatably connected to the inner wall of the support frame 43. The output end of the third motor 44 is fixedly connected to one end of the gear 45. One end of the clamping frame 46 has a through groove 461. The inner wall of the other end of the clamping frame 46 is fixedly connected to a rotating sleeve 462. The outer wall of the rotating sleeve 462 is fixedly connected to a toothed ring 463 that meshes with the gear 45. Two sets of symmetrical guide plates 464 are fixedly connected to the inner walls of both sides of the clamping frame 46. Four second cylinders 47 are symmetrically fixedly connected to the inner walls of both sides of the fixed frame 41. The telescopic end of the second cylinder 47 is fixedly connected to one end of the clamping block 48. A set of support plates 481 is fixedly connected to one side of the clamping block 48. A roller shaft 49 is rotatably connected between the support plates 481. One end of the clamping block 48 is fixedly connected to a slide rod 482 that is slidably connected to the inner wall of the support plate 481. It should be noted that: This device is installed at one end of the pipe clamping device, which fixes the end of the pipe fitting. Then, the other end of the pipe fitting passes through the chuck assembly 4, thus fixing the end to be clamped. After the pipe fitting passes through the entire chuck assembly 4, two sets of mutually perpendicular second cylinders 47 are driven synchronously, moving the clamping block 48 at one end. This causes the roller 49 on one side of the clamping block 48 to gradually approach the pipe fitting until the two sets of four symmetrically arranged rollers 49 complete the clamping of the pipe fitting. Because the symmetrically arranged second cylinders 47 are driven synchronously, self-centering clamping and fixing of the pipe fitting can be achieved, ensuring the position of the pipe fitting. Located at the center of the entire chuck assembly 4, it ensures the cutting accuracy of subsequent pipe fittings. During the pipe fitting cutting process, the third motor 44 can be activated to drive the gear 45 to rotate. When the gear 45 rotates, it meshes with the gear ring 463 on one side, driving the rotating sleeve 462 to rotate. While the rotating sleeve 462 rotates, the clamping frame 46 at one end will drive the pipe fitting fixed inside to rotate. During the rotation, the cutting components set above can cut multiple outer walls of the pipe fitting in different ways without manually changing the cutting surface of the pipe fitting. Cutting and drilling operations can be performed on different outer walls of the pipe fitting according to the requirements, thereby improving the overall cutting efficiency.

[0018] Furthermore, the cutting assembly includes a fixed frame 2, a mounting frame 3, and a laser head 33. A first slider 21, which is slidably connected to the inner wall of the first slide groove 13, is fixedly connected to one side of the fixed frame 2. The first slider 21 is threadedly connected to the first lead screw 14. A second lead screw 22 is rotatably connected to the inner wall of the fixed frame 2. A second motor 23 is installed at one end of the fixed frame 2. The output end of the second motor 23 is fixedly connected to one end of the second lead screw 22. A second slider 31, which is slidably connected to the inner wall of the fixed frame 2, is fixedly connected to one end of the mounting frame 3. The second slider 31 is threadedly connected to the second lead screw 22. A limit groove 32 is opened on one side of the mounting frame 3. A hydraulic cylinder 36 is installed at the upper end of the mounting frame 3. A slide plate 34, which is slidably connected to the inner wall of the limit groove 32, is fixedly connected to one side of the laser head 33. A limit plate 35 is fixedly connected to one end of the slide plate 34. The upper end of the limit plate 35 is fixedly connected to the telescopic end of the hydraulic cylinder 36.

[0019] It should be noted that the laser head 33 can achieve precise cutting of pipes through the cutting assembly. During operation, the first motor 15 drives the first lead screw 14 to rotate. Since the first slider 21 is threadedly connected to the first lead screw 14 and slidably connected to the inner wall of the first slide groove 13, the rotation of the first lead screw 14 will drive the first slider 21 to move smoothly along the first slide groove 13, thereby driving the entire fixed frame 2 to move, so that the cutting assembly has a preliminary position adjustment in the horizontal direction. At the same time, the hydraulic cylinder 36 drives the limiting plate 35 to move up and down through the telescopic action, so that the slide plate 34 slides smoothly in the limiting groove 32, ensuring that the position of the laser head 33 can be flexibly adjusted as needed. This design not only improves the cutting accuracy, but also enhances the stability and durability of the equipment. Afterwards, the second motor 23 drives the second lead screw 22 to rotate, further driving the mounting frame 3 to move along the inner wall of the fixed frame 2, realizing the coordinated operation of the cutting assembly in multiple directions and meeting the cutting needs of different angles and positions. Each motor is controlled via a terminal. When cutting the pipe tail, a portion of the end of the pipe is held in the pipe clamping device. When the overall length of the tail is sufficient for another cut, the clamping device prevents the cutting surface from being positioned at the end of the pipe. In this case, the terminal controls the laser head 33 to move towards one side of the chuck assembly 4 to avoid the obstruction. Subsequently, the first cylinder 18 is driven to move the entire chuck assembly 4 until one side of its fixing frame 41 approaches the laser head 33. At this point, the pipe clamping device releases the end of the pipe, and the laser head 33 cuts the end of the pipe, thus completing the cutting of the tail. By changing the position of the chuck assembly 4, the pipe can be cut from the other end, enabling the cutting of the tail and avoiding the need for manual cutting of excessively long tails after unloading, thereby improving the overall cutting efficiency.

[0020] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
