Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0019] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a mechanical connection or an electrical connection.

[0020] like Figure 1 and 2 As shown, a triaxial eccentric straight seam welding auxiliary device includes a base plate 1 with two workstations on the base plate 1. Each workstation is equipped with a clamping and positioning mechanism, which includes a feeding platform 8, a horizontal clamping assembly, and a vertical clamping assembly. The feeding platform 8 is used to place the pipe to be welded. The feeding platform 8 is hollow inside and has a limiting block 9. The upper surface of the feeding platform 8 has an eccentric vent hole 10 located on one side of the central axis of the feeding platform 8. The feeding platform 8 is connected to an external air source through an air pipe. The main function is to use a protective gas, such as an inert gas, which is discharged from the eccentric vent hole during the welding process, providing protection and increasing the gloss of the product.

[0021] The limiting block 9 is provided with a slot 11, which is directly opposite the eccentric air outlet 10. The eccentric air outlet 10 is elongated and extends along the axial direction of the feeding platform 8. The opening of the slot is inclined to facilitate the placement and limiting of the pipe.

[0022] The limiting block 9 can be locked to the feeding table 8 with screws. The pipe is placed in the slot and is pushed against it, which plays a limiting role.

[0023] In addition, a gasket 12 is laid on the feeding platform 8, and the gasket 12 has a groove 13, which is directly opposite the eccentric air hole 10. The thickness of the gasket can be selected. By installing the gasket, the height of the feeding platform is increased, thereby accommodating pipes of different specifications and sizes and improving the applicability to the product.

[0024] The feeding platform 8 is installed on the feeding support frame 7, and the bottom surface of the feeding support frame 7 is installed on the base plate 1.

[0025] The transverse clamping assembly includes a transverse cylinder 3, a clamping support frame 2, and a transverse top block 4. The bottom surface of the clamping support frame 2 is mounted on the base plate 1, the transverse cylinder 3 is mounted on the clamping support frame 2, and the transverse top block 4 is connected to the piston of the transverse cylinder 3. The transverse cylinder 3 drives the transverse top block 4 to move towards the discharge platform 8, thereby clamping the pipe in the horizontal direction.

[0026] Two vertical clamping assemblies are provided, one mounted on the feeding support frame 7 and the other on the clamping support frame 2. The vertical clamping assembly includes a vertical cylinder 6 and a vertical top plate 5. The piston of the vertical cylinder 6 is connected to the vertical top plate 5, which is located above the feeding platform. The vertical cylinder drives the vertical top plate to move downward, clamping the pipe from top to bottom.

[0027] By manually placing the pipes on the feeding platform and adjusting their position, the direction of the feeding platform is perpendicular to the direction of movement of the horizontal top block. Combined with the vertical top block, this forms a three-axis direction, achieving effective fastening.

[0028] In addition, a material box 14 is provided between the two workstations to facilitate the placement of pipes.

[0029] During operation, place the product to be welded on the feeding platform, hold the limit block in place, and press the start button. The vertical cylinder presses down, causing the vertical top block to press down on the product, while the horizontal cylinder drives the horizontal top block to clamp the product, completing the clamping and positioning of the product. Welding begins, and after welding is complete, the product is removed. The eccentric air outlet on the feeding platform is used to blow protective gas. During welding, the protective gas is turned on to increase the gloss of the product. Gaskets of different thicknesses are provided for pipes of different sizes; different thickness gaskets are used when welding different products.

[0030] It should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
