[0021] like Figures 1 to 2 As shown, a round tube welding auxiliary device includes a support frame, a roller assembly is provided on the support frame, and the roller assembly includes two groups of rollers 1 arranged at intervals. The rollers 1 are movably mounted on the support frame, and a mounting groove for placing the round tube is formed between the two groups of rollers 1. The distance between the two groups of rollers 1 can be adjusted to accommodate the placement of round tubes of different diameters.

[0022] By adopting the above arrangement, a mounting groove is formed between the two rollers 1, and the tubular material is fixed on the support frame, so that the tubular material can be stable, which facilitates the rotation of the round tube and the rolling of the roller 1 to achieve smooth rotation of the round tube for welding, making the welding work more precise, reducing labor intensity, improving welding efficiency and welding quality, facilitating batch welding processing, and solving the problem of low execution efficiency of manual moving auxiliary welding in welding work.

[0023] Specifically, the distance between the rollers 1 is adjustable, ensuring that the rollers 1 can better adapt to round tubes or other tubular materials of different diameters. In this way, the auxiliary device can perform welding work on tubular or cylindrical workpieces of different specifications.

[0024] Preferably, multiple groups of roller assemblies are provided on the support frame, and multiple groups of rollers 1 support the round tube workpiece to improve the support stability. At the same time, when the round tube is rotated, the rolling of multiple rollers 1 drives the round tube to rotate more smoothly.

[0025] In the round tube welding auxiliary device of this embodiment, the roller assembly also includes a mounting frame unit, which includes two mounting frames 2 arranged opposite to each other and mounted on a support frame. The mounting frames 2 are arranged perpendicular to the support frame, and the roller 1 is installed on the mounting frames 2.

[0026] With the above arrangement, by arranging the support frame perpendicular to the mounting frame 2 and placing rollers 1 on the mounting frame 2, the mounting grooves between the rollers 1 are parallel to the extension direction of the support frame, thereby facilitating placement of the tubular workpiece on the support frame.

[0027] In the round tube welding auxiliary device of this embodiment, the mounting frame unit also includes a mounting shaft, the roller 1 is sleeved on the mounting shaft and rotatably connected to the mounting shaft, the mounting shaft is arranged parallel to the extension direction of the support frame, and the mounting shaft includes a fixed mounting shaft 3 fixedly connected to the mounting frame and a movable mounting shaft 4 detachably connected to the mounting frame.

[0028] By adopting the above-mentioned setting, by setting the mounting shaft on the mounting frame 2, support is provided for the roller 1, and stable rotation of the roller 1 is achieved. The installation position of the movable mounting shaft 4 on the mounting frame 2 is adjusted to change its distance from the fixed mounting shaft 3 to achieve the purpose of adjusting the spacing between the rollers 1, thereby achieving stable support for round pipes of different diameters, expanding the adaptability of the welding auxiliary device, and improving the practicality of this application.

[0030] With the above arrangement, a plurality of equidistant limit blocks 5 are provided on the mounting frame 2 to form a limit groove, thereby further limiting the position of the movable mounting shaft 4 and fixing the spacing of the rollers 1, so that the round tube can be stably placed in the mounting frame unit.

[0031] Preferably, the end of the limit block 5 away from the movable installation shaft 4 is fixedly connected to a stop block to limit the axial direction of the movable installation shaft 4 to prevent the movable installation shaft 4 from sliding axially in the limit groove and causing unstable rotation of the roller 1.

[0032] In the round tube welding auxiliary device of this embodiment, two groups of roller assemblies are provided along the extension direction of the support frame, the two groups of roller assemblies are arranged at the same height, and the distance between the two groups of roller assemblies is adjustable.

[0033] By adopting the above-mentioned setting, two sets of equal-height parallel rolling assemblies are respectively provided, thereby ensuring that the round tube workpiece is in a stable horizontal suspension, supporting the round tube from both ends, improving the stability of the round tube installation and rolling, and making the welding work more convenient; the spacing between the two sets of roller assemblies is adjustable, and by adjusting the spacing, the present application can be applied to round tubes of different lengths, thereby improving the welding efficiency.

The distance between the two sets of roller assemblies allows adjustment, thereby meeting the installation and welding requirements of round pipes of different lengths. It is set as a sliding connection, which increases the position adjustment range of the sliding roller assembly and is easy to adjust.

[0036] Specifically, the mounting frame 2 in the fixed roller assembly is fixedly connected to the support frame, and the sliding roller assembly includes a mounting frame 2 slidably connected to the support frame, and the position of the roller 1 on the support frame is adjusted by the sliding mounting frame 2.

A sliding groove is formed between the limit plates 7, and a protrusion 8 is fixed at one end of the support plate 6.

[0038] With the above-mentioned setting, a limit plate 7 is provided to limit the two ends of the mounting frame 2 to form a sliding groove, so that the sliding roller assembly can slide in the sliding groove along the extension direction of the support frame to smoothly adjust the distance between the two roller assemblies; a protrusion 8 is provided to limit the mounting frame 2 in the sliding roller assembly to prevent the sliding roller assembly from sliding off the support frame.

[0039] In the round pipe welding auxiliary device of this embodiment, movable wheels 9 are provided below the support frame, and two groups of movable wheels 9 are provided at intervals along the extending direction of the support frame.
