[0026] The technical solution of the present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0027] Example

[0028] This embodiment provides a follow-up support mechanism for a laser tube cutting machine, such as Figure 1-3 As shown, its structure includes a base plate 11, a wedge-shaped mounting plate 15, a follower fixing seat 12, a lifting slide plate 16, a roller, a support plate 17, a first driving cylinder 18, a first guide rail slider assembly 13, a follower pull rod 14 and other components.

[0029] Preferably, in the follow-up support mechanism of a laser tube cutting machine of the present embodiment, the base plate 11 is fixedly connected to the side plate of the laser tube cutting machine bed, serving as the basis of the entire follow-up support mechanism. The wedge-shaped mounting plate 15 is slidably arranged on the base plate 11 in the horizontal direction, and stable sliding is achieved through the first guide rail slider assembly 13. The first guide rail slider assembly 13 includes a first guide rail and a second guide rail arranged in parallel, and a first slider and a second slider slidably connected to the two guide rails, and the first slider and the second slider are staggered in the sliding direction to improve sliding stability.

[0030] Preferably, in the follow-up support mechanism of a laser tube cutting machine of the present embodiment, the follow-up fixing seat 12 is fixedly connected to the bottom plate 11, and a lifting slide 16 is slidably arranged on the bottom plate 11. A roller 21 is arranged on the lifting slide 16, and the roller 21 abuts against the inclined surface of the wedge-shaped mounting plate 15. When the follow-up driving device drives the multiple wedge-shaped mounting plates 15 to slide synchronously in the horizontal direction, the roller 21 rolls on the inclined surface, thereby driving the multiple lifting slides 16 to rise and fall synchronously.

[0031] Preferably, in the follow-up support mechanism of the laser tube cutting machine of this embodiment, the support plate 17 is hinged on the top of the lifting slide 16 to support the tube. The bottom of the cylinder seat of the first driving cylinder 18 is hinged on the lifting slide 16, and the end of the telescopic rod is hinged on the support plate 17. By controlling the extension and retraction of the telescopic rod of the first driving cylinder 18, the support plate 17 can be driven to rotate around the hinge point, thereby adjusting the inclination angle of the support plate 17 and automatically unloading the cut tube.

[0032] Preferably, in the follow-up support mechanism of a laser tube cutting machine of the present embodiment, in order to further improve the lifting stability of the lifting slide 16, a second driving cylinder 19 and a second guide rail slider assembly 20 are further provided between the follow-up fixed seat 12 and the lifting slide 16. The second driving cylinder 19 can directly drive the lifting action of the lifting slide 16, while the second guide rail slider assembly 20 ensures the stable sliding of the lifting slide 16 in the Z-axis direction. It should be noted that the lifting action of the second driving cylinder 19 is synchronized with the lifting action of the roller pushed by the wedge-shaped mounting plate 15, so that the roller 21 is always in contact with the wedge-shaped mounting plate 15, ensuring the synchronous lifting of multiple pallets 17.

[0033] Preferably, in the follow-up support mechanism of a laser tube cutting machine of the present embodiment, the follow-up pull rod 14 is connected to the follow-up drive device on the side plate of the bed of the laser tube cutting machine. When the tube is cut on the bed of the laser tube cutting machine, the follow-up drive device moves horizontally, which drives the follow-up pull rod 14 to move, and then drives the wedge-shaped mounting plate 15 to slide in the horizontal direction. Since the roller abuts against the inclined surface of the wedge-shaped mounting plate 15, the sliding of the wedge-shaped mounting plate 15 drives the lifting slide plate 16 to rise and fall, thereby realizing the height adjustment of the follow-up support mechanism.

[0034] In practical applications, multiple follow-up support mechanisms can be set on the side plates of the laser tube cutting machine to support tubes at different positions. The follow-up pull rods 14 of multiple follow-up support mechanisms can be connected to the action output end of the same follow-up drive device to achieve synchronous action of multiple follow-up support mechanisms. In this way, no matter where the tube is in the laser tube cutting machine, it can be stably supported, thereby improving the cutting quality.

[0035] Based on the above ideal embodiments of this application, the relevant staff can make various changes and modifications without departing from the technical concept of this application through the above description. The technical scope of this application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
