[0002] With the continuous development of industrial automation technology, fiber laser tube cutting machines have been widely used in the cutting and processing of various metal tubes. How to ensure the stability, positioning accuracy and adaptability of the tubes during the cutting process has become a major challenge in the design of fiber laser tube cutting machines.

[0003] During the use of laser tube cutting machines, the most common problem is the broken tube ends. In detail, due to the special shape of the tubes, the ends are prone to collision and deformation during transportation and need to be cut off. In this process of tube breaking, a tube support device is indispensable. However, the existing tube support device mainly relies on the cylinder to drive the scissor rod to support tubes of different diameters. Although it can provide certain support for tubes of different diameters, its accuracy is poor. In addition, it cannot finely adjust the specific length of the tube breaking process. Approximate positioning will lead to more cutting and increased costs. For this reason, practitioners have designed a tube support device for fiber laser tube cutting machines. Utility Model Content

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Example 1:

[0027] Combine Figure 1-5The fiber laser tube cutting machine shown in the figure comprises a tube cutting machine body 1, which carries other components. An operating table 2 is provided on one side of the tube cutting machine body 1. The operating table 2 provides a platform for the operator to operate and adjust the machine equipment, making the operation more convenient and efficient. A chuck 3 is provided at one end of the upper surface of the tube cutting machine body 1. The chuck 3 is a key component for fixing and rotating the tube. A laser cutting head 4 is provided on the chuck 3. The laser cutting head 4 focuses and guides the laser beam to the surface of the tube through a precise control system, thereby achieving efficient and fine cutting. A tube adjustment mechanism 5 is provided at the end of the tube cutting machine body 1 away from the chuck 3. The function of this mechanism is to accurately adjust the groove length of the tube to be cut and ensure the correct alignment of the tube during the cutting process to avoid over-cutting. Several groups of support mechanisms 6 are evenly distributed in the cavity of the tube cutting machine body 1. These support mechanisms play a role in stabilizing and supporting the tube.

[0028] The supporting mechanism 6 includes two groups of supporting base plates 601 relatively arranged on the pipe cutting machine bed 1, and a reducing wheel 602 is rotatably arranged between the two groups of supporting base plates 601. The design of the reducing wheel 602 enables the equipment to adapt to pipes of different diameters, automatically adjust the diameter of the adapted pipe, and improve the versatility of the equipment. Several groups of pin holes 603 are evenly distributed on the side wall of the reducing wheel 602, and a dividing pin 604 that matches the pin hole 603 is provided on one of the groups of supporting base plates 601. By positioning different pin holes 603 by the dividing pin 604, the depth change of the corresponding supporting position of the reducing wheel 602 can be achieved, thereby ensuring stable support of the pipe during the cutting process, and providing an ideal working environment for subsequent laser cutting.

[0029] In this embodiment, the Figure 3 The pipe adjustment mechanism 5 shown in the figure has a relatively sophisticated design structure and is mainly composed of several key components, including a screw rod 501 rotatably arranged on one side of the upper surface of the pipe cutting machine bed 1, and a guide rail 502 fixedly arranged on the other side of the pipe cutting machine bed 1. An adjustment motor 503 is provided at one end of the screw rod 501 to drive its rotation. The linear movement of the pipe adjustment mechanism 5 is achieved by rotating the screw rod 501. The motor 503 accurately controls the rotation of the screw rod 501, so that the entire pipe adjustment mechanism 5 can be adjusted preliminarily and efficiently. The screw rod 501 is provided with a motor 503 that cooperates with it. The ball nut base 504 is provided with a slider 505 that cooperates with it on the guide rail 502. The function of the slider 505 is to carry and support the sliding parts and work together with the ball nut base 504. An adjustment base plate 506 is provided between the ball nut base 504 and the slider 505. The adjustment base plate 506 plays a connecting and bearing role in the entire mechanism. A fine-tuning component 507 is provided on the adjustment base plate 506. The fine-tuning component 507 provides a further precise fine-tuning function for the position of the pipe, so that every detail in the cutting process can be precisely controlled.

[0030] In this embodiment, the Figure 4 The fine-tuning assembly 507 shown includes a fine-tuning cylinder 5071 fixedly arranged on the adjustment base plate 506. The fine-tuning cylinder 5071 serves as a driving element and has the characteristics of high precision and rapid response. Its main function is to achieve small displacement adjustment by controlling the extension and contraction of the cylinder, thereby accurately controlling the adjustment of the pipe. A fine-tuning push plate 5072 is provided on the telescopic rod of the fine-tuning cylinder 5071. The design of the fine-tuning push plate 5072 enables the extension and contraction action of the cylinder to directly act on the adjustment of the pipe. The precise control of the push plate 5072 enables even small displacements to be accurately achieved during the cutting process, meeting the processing requirements of different pipes.

[0031] In this embodiment, the Figure 5 The mounting base of the screw rod 501 shown is provided with an anti-collision member 508, whose main function is to protect the ball nut base 504 from external force collision or accidental impact. The anti-collision member 508 includes a fixing bolt 5081, which is used to firmly fix the anti-collision member 508 on the mounting base to ensure that it will not loosen during use. An anti-collision column 5082 is provided at the end of the fixing bolt 5081. The anti-collision column 5082 is a key component of the anti-collision member 508, which is designed to absorb impact force in the event of a collision.

[0032] In this embodiment, digital markings are provided on the side walls of the variable diameter wheel 602 located at the pin hole 603. The digital markings are set on the side walls of the variable diameter wheel 602, which makes it easy for the operator to quickly and accurately read and confirm the depth position or specifications corresponding to the current variable diameter wheel 602 during the adjustment process. These digital markings are usually presented in a clear and easy-to-read digital form, which can be scales, numbers or digital values ​​related to specific process parameters, helping the operator to quickly identify the set value of the variable diameter wheel 602 and ensure accuracy during the adjustment process.
