[0002] At present, laser cutting technology has been widely applied in the field of metal processing. Especially in the processing of round pipe workpieces, laser pipe cutting machines are widely welcomed due to their high precision and high efficiency.

[0003] In the prior art, during the cutting process of round pipe workpieces by a laser cutting machine, a supporting mechanism is required to stably support the round pipe workpieces to prevent displacement or vibration of the round pipe workpieces during the cutting process, thereby affecting the cutting precision. However, traditional supporting mechanisms usually use V-shaped rollers for support. Since the angle of the V-shaped rollers is fixed, the supporting effect is not ideal enough when processing workpieces of different sizes. Especially when supporting round pipe workpieces with a larger diameter, the stability is lacking, and it is difficult to flexibly adjust to adapt to round pipe workpieces of different diameters. And for some pipe supporting mechanisms with variable angles, their structures are generally more complex, and the operation process is cumbersome when adjusting and supporting different round pipe workpieces, thus affecting the processing efficiency of the laser pipe cutting machine.

[0028] The following will further illustrate the technical solutions of the present utility model in conjunction with the drawings and through specific implementation manners.

[0029] Such as Figures 1 to 4As shown in the figure, an embodiment of the present utility model provides a pipe support mechanism for a laser pipe cutting machine, which includes a base 1, slide rails 2, a bidirectional lead screw 3, a first rotating handle 4, a moving carrier plate 5, a first arc-shaped support rod 61, a second arc-shaped support rod 62, and a pipe support roller 7. The two slide rails 2 are respectively arranged on both sides of the base 1. The two moving carrier plates 5 are respectively movably connected to the slide rails 2 through sliders. The moving carrier plate 5 can move along the extension direction of the slide rails 2. The bidirectional lead screw 3 is arranged between the two slide rails 2. Different-threaded portions (not shown) are respectively arranged at both ends of the bidirectional lead screw 3. A threaded seat 51 is arranged on the moving carrier plate 5. The threaded seat 51 is threadedly connected to the threaded portion. The threaded seat 51 is used to drive the two moving carrier plates 5 to move towards or away from each other as the bidirectional lead screw 3 rotates. The bottoms of the first arc-shaped support rod 61 and the second arc-shaped support rod 62 are respectively connected to the moving carrier plate 5, and the first arc-shaped support rod 61 and the second arc-shaped support rod 62 are movably connected through a pin shaft 60. The tops of the first arc-shaped support rod 61 and the second arc-shaped support rod 62 are respectively connected to the pipe support roller 7. The pipe support roller 7 is used to abut and support the round pipe workpiece to be cut. The operator can adjust the position of the moving carrier plate 5 by rotating the first rotating handle 4 on the bidirectional lead screw 3 according to the diameter of the round pipe workpiece to be cut. Since different-threaded portions are arranged at both ends of the bidirectional lead screw 3, as the bidirectional lead screw 3 rotates, the distance between the two moving carrier plates 5 will change driven by the threaded seat 51, and then drive the first arc-shaped support rod 61 and the second arc-shaped support rod 62 to swing around the pin shaft 60, so as to adjust the distance between the two pipe support rollers 7 to adapt to supporting round pipe workpieces of different diameters, improve the support stability for round pipe workpieces of different diameters, and prevent the round pipe workpiece from shifting or shaking during the cutting process; moreover, the operation of this pipe support mechanism is simple and can be adjusted quickly, effectively improving the applicability and processing efficiency of the laser pipe cutting machine.

[0030] As Figure 4 shown, further, the number of both the first arc-shaped support rod 61 and the second arc-shaped support rod 62 is two. The two first arc-shaped support rods 61 are connected by a first rib plate 63, and the two second arc-shaped support rods 62 are connected by a second rib plate 64. With such a setting, the strength and stability of the entire overall structure can be improved, and the risk of bending or deforming when bearing a larger workpiece can be avoided.

[0031] As Figure 2 shown, further, the first arc-shaped support rod 61 and the second arc-shaped support rod 62 have the same structure. An arc-shaped groove 600 for abutting against the bottom of the round pipe workpiece is provided on the upper surface of the first arc-shaped support rod 61 and the second arc-shaped support rod 62. The arc-shaped groove 600 can better fit the bottom of the round pipe workpiece, thereby improving the support stability for the round pipe workpiece.

[0032] As Figure 1 and Figure 2 shown, further, it further includes a positioning and locking assembly 8. A plurality of the positioning and locking assemblies 8 are arranged at the corners of the base 1. The positioning and locking assembly 8 includes a mounting seat 81, a positioning screw 82, and a second rotating handle 83. The mounting seat 81 is arranged on the base 1. The positioning screw 82 is vertically arranged on the mounting seat 81. The second rotating handle 83 is arranged at the top of the positioning screw 82. The second rotating handle 83 is used to drive the positioning screw 82 to rotate. Through the positioning and locking assembly 8, it is convenient to lock and fix the base 1 on the frame of the laser pipe cutting machine, prevent the pipe supporting mechanism from shifting during use, improve the overall structural stability, and the locking connection method of the positioning and locking assembly 8 is simple. Just align the positioning screw 82 with the reserved threaded hole on the laser pipe cutting machine, and then rotate and adjust the second rotating handle 83.

[0033] Further, the pipe supporting roller 7 is made of rubber or metal. In this embodiment, the pipe supporting roller 7 is made of rubber. The rubber pipe supporting roller 7 not only has softness but also has a high friction coefficient, and can provide better friction force when supporting and fixing the round pipe workpiece, preventing the round pipe workpiece from slipping or shifting during cutting.

[0034] Further, a support spacing is formed between the axes of the two pipe supporting rollers 7. The support spacing is 200 - 1200 mm. In this embodiment, the support spacing is 1000 mm.

[0035] Further, the diameter of the pipe supporting roller 7 is 50 - 300 mm. In this embodiment, the diameter of the pipe supporting roller 7 is 200 mm. When the pipe supporting roller 7 with a larger diameter contacts the round pipe workpiece, a larger contact area will be formed, thereby evenly dispersing the load of the round pipe workpiece and improving the support stability.

[0036] The above is described. 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 foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
