When it is necessary to clamp and support tube fittings of different diameters, the operator needs to manually adjust the concentricity between the tube diameter and the laser tube cutting machine chuck, which has low production efficiency; in addition, the support height of the traditional tube clamping mechanism cannot be adjusted in sections, making it difficult to adapt to various shapes of special-shaped tube fittings, and has low flexibility. It is impossible to quickly support tube fittings of different shapes, resulting in reduced stability and precision during the cutting process, affecting the cutting effect.

[0004] Therefore, the existing technology has defects and needs to be improved. Utility Model Content

[0030] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0031] like Figure 1 As shown, the embodiment of the utility model provides an adaptive pipe clamping mechanism for a laser pipe cutting machine, comprising a frame 1, a linkage lifting assembly 2, a lifting plate 3, a lifting cylinder 4, and a pipe clamping support assembly 5;

[0032] The linkage lifting assembly 2 is arranged on the frame 1, and multiple lifting plates 3 are connected to the linkage lifting assembly 2. The linkage lifting assembly 2 is used to drive multiple lifting plates 3 to lift synchronously. The lifting cylinder 4 is arranged on the lifting plate 3, and the movable end of the lifting cylinder 4 is set upward and connected to the pipe clamping support assembly 5. The pipe clamping support assembly 5 is used to support the pipe to be cut to prevent the pipe from shaking during the cutting process, thereby improving the cutting accuracy. The linkage lifting assembly 2 can simultaneously drive multiple pipe clamping support assemblies 5 to lift synchronously, avoiding the shaking of pipes caused by height differences, and has good structural stability. It effectively reduces the tedious manual adjustment of the operator, saves time and effort, and improves production efficiency. The setting of the lifting cylinder 4 enables each pipe clamping support assembly 5 to be individually lifted and adjusted to adapt the support height according to the size and shape of different pipe fittings, thereby meeting the support requirements of various pipe fittings, with high flexibility and effectively improving the versatility of the pipe clamping mechanism.

[0033] like Figure 3 As shown, the pipe clamping support assembly 5 includes a bearing plate 51, a V-shaped roller 52 and a parallel roller 53. The movable end of the lifting cylinder 4 is connected to the bearing plate 51 through a pipe joint. The V-shaped roller 52 and the parallel roller 53 are arranged on the bearing plate 51. The V-shaped roller 52 and the parallel roller 53 are used to support the pipe fittings; the V-shaped roller 52 can provide lateral support for the pipe fittings to prevent the round pipe fittings from rolling during the cutting process, and the parallel roller 53 provides linear support for the pipe fittings to ensure that the pipe fittings remain stable during the cutting process and are not easy to tilt or move. The V-shaped roller 52 and the parallel roller 53 are arranged in coordination with each other to ensure that the pipe fittings are always in the best support state.

[0034] like Figure 2 As shown, the linkage lifting assembly 2 includes a drive motor 21, a rotating shaft 22, and an elevator 23. The rotating shaft 22 extends along the length direction of the frame 1. The output shaft of the drive motor 21 is connected to the rotating shaft 22 to drive the rotating shaft 22 to rotate. The input end of the elevator 23 is connected to the rotating shaft 22, and the output end of the elevator 23 is connected to the lifting plate 3 through a threaded rod 24. The elevator 23 is used to push the lifting plate 3 to move up and down as the rotating shaft 22 rotates. When the drive motor 21 is started, the drive motor 21 can drive the rotating shaft 22 to rotate. Since the rotating shaft 22 is connected to the input end of the elevator 23, and the output end of the elevator 23 is connected to the lifting plate 3 through the threaded rod 24, the rotational motion is converted into a linear lifting motion of the lifting plate 3, so as to achieve synchronous lifting and adjustment of multiple lifting plates 3.

[0035] like Figure 2 and Figure 3 As shown, the linkage lifting assembly 2 further includes a first sliding bearing 25 and a first sliding rod 26. Support bases 10 are provided on both sides of the frame 1. The first sliding bearing 25 is disposed in the support base 10. The first sliding rod 26 is sleeved in the first sliding bearing 25. The top of the first sliding rod 26 is connected to the lifting plate 3. The provision of the first sliding bearing 25 and the first sliding rod 26 can improve the lifting and moving stability of the lifting plate 3.

[0036] like Figure 3 As shown, the lifting plate 3 further includes a second sliding bearing 31 and a second sliding rod 32. The second sliding bearing 31 is provided on the lifting plate 3 on both sides of the lifting cylinder 4. The second sliding rod 32 is sleeved in the second sliding bearing 31. The top of the second sliding rod 32 is connected to the supporting plate 51. The provision of the second sliding bearing 31 and the second sliding rod 32 can improve the lifting and lowering stability of the supporting plate 51.

[0037] like Figure 2 As shown, the rotating shaft 22 further includes a plurality of bearing blocks 27, which are arranged along the length of the rotating shaft 22 and are sleeved with the rotating shaft 22. The bearing blocks 27 can reduce friction during the rotation of the rotating shaft 22, thereby reducing wear and effectively extending the service life of the rotating shaft 22.

[0038] like Figure 3As shown, further, it also includes a sensing piece 281, a proximity switch 282 and a mounting base 283. The mounting base 283 is provided at the bottom of the frame 1, the proximity switch 282 is provided on the mounting base 283, the sensing piece 281 is provided on the side wall of the jacking plate 3, and the proximity switch 282 is used to control the driving motor 21 to stop after the jacking plate 3 is lowered to a predetermined position. When the jacking plate 3 is lowered to the predetermined position, the sensing piece 281 is close to the proximity switch 282. After the proximity switch 282 detects the position change of the sensing piece 281, it can send a signal to control the driving motor 21 to stop, thereby ensuring that the jacking plate 3 can accurately stop at the set height and avoid excessive descent.

[0039] Furthermore, the angle of the V-shaped roller 52 is 120°. This configuration allows the V-shaped roller 52 to be applicable to pipes of various diameters. Whether it is a pipe with a smaller diameter or a pipe with a larger diameter, it can be effectively supported at the angle of the V-shaped roller 52, effectively improving the versatility of the pipe clamping mechanism.

[0040] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
