[0005] Preferably, the lifting foot is formed by screwing an outer cylinder seat and an inner cylinder, and the double-ball universal wheel and the quick clamp are fixed at the bottom by screws with a circular cover covering the top of the inner cylinder.

[0006] Preferably, fastening screws are provided on the outer side of the outer cylinder seat of the lifting foot; further ensuring the support stability.

[0007] Preferably, the quick clamp is fixed to the U-shaped fixing piece by screws, and the U-shaped fixing piece 6 is fixed at the bottom by screws with a circular cover covering the top of the inner cylinder.

[0008] Preferably, the lower pressing end of the quick clamp is an annular frame, and the double-ball universal wheel is installed at the bottom of the lower pressing end through two groups of bolts, nuts and washers.

[0009] Preferably, the guide rail is a double guide rail, respectively located below the two groups of lifting feet; the sliders are two pieces.

[0010] The beneficial effects of the utility model: the structure is simple and convenient for processing and manufacturing, improving the pipe cutting operation efficiency, easy to use, can be quickly clamped and disassembled, and is applicable to round pipes of different specifications. Brief Description of the Drawings

[0011] Figure 1 This is the structural schematic diagram of the present utility model. Specific embodiments

[0012] As Figure 1 As shown in the figure, a positioning and supporting device for a laser pipe cutting machine includes lifting feet 1, double-ball universal wheels 2 and quick clamps 3; the double-ball universal wheels 2 and the quick clamps 3 are respectively installed on two groups of lifting feet 1, there is a gap between the two groups of lifting feet 1, another group of double-ball universal wheels 2 is fixed at the pressing end of the quick clamp 3, and after the quick clamp 3 is pressed down, the two groups of double-ball universal wheels 2 are located in the same vertical plane; connecting plates 4 are fixed at the bottoms of the two groups of lifting feet 1; it also includes guide rails 5; the connecting plates 4 are slidably installed on the guide rails 5 through sliders.

[0013] The lifting foot 1 is formed by screwing an outer cylinder seat and an inner cylinder, and the double-ball universal wheel 2 and the quick clamp 3 are fixed at the bottom by screws with a circular cover covering the top of the inner cylinder. The quick clamp 3 is fixed to the U-shaped fixing piece 6 by screws, and the U-shaped fixing piece 6 is fixed at the bottom by screws with a circular cover covering the top of the inner cylinder. When rotating the lifting inner cylinder, it can be adjusted or, when placing a round pipe, the directions of the double-ball universal wheel 2 and the quick clamp 3 remain unchanged.

[0014] The pressing end of the quick clamp 3 is an annular frame 31, and the double-ball universal wheel 2 is installed at the bottom of the pressing end through two groups of bolts 32, nuts 33 and washers 34. The guide rail 5 is a double guide rail, which is respectively located below the two groups of lifting feet 1; the sliders are two pieces.

[0015] The present utility model is fixedly installed on the table of the laser pipe cutting machine through the guide rail 5 in the same axial direction as the installation of the round pipe; it is used to support the other end of the round pipe.

[0016] The present utility model utilizes the existing quick clamp 3 (also called a horizontal quick clamp) as a quick tightening and loosening clamp, its pressing end is an annular frame, and the double-ball universal wheel 2 is installed at the bottom of the pressing end through two groups of bolts 32, nuts 33 and washers 34. And the double-ball universal wheel 2 for support is directly installed on the lifting foot 1. In this way, after supporting the round pipe, the height of the inner cylinder of the lifting foot 1 can be adjusted by screwing, and the handle of the quick clamp 3 is pressed down to make the double-ball universal wheel 2 press on the top of the round pipe. And the double-ball universal wheel 2 is designed as a support, which can adapt to round pipes of different specifications and sizes placed between the two balls; and after the upper and lower double-ball universal wheels 2 are pressed, there is no need to over-press. This combination can move forward along the round pipe under the guidance of the guide rail 5, that is, the round pipe can be cut section by section without disassembly and without re-clamping.

[0017] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements or improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
