Background
At present, the equipment is generally manually and directly aligned when being welded and assembled, the alignment misalignment of pipe ends is basically out of tolerance, gaps are not formed or are inconsistent in size, and therefore a welded joint cannot be completely welded, inner wall forming is not good, and the appearance of the welded joint does not reach the standard.
The equipment piping generally comprises hydraulic, water-cooling, pneumatic and lubricating pipelines, most pipelines adopt welding types, and welding joints need to be formed by single-side welding and double-side welding. In order to ensure the quality of the welding joint, the butt joint misalignment amount and the welding gap of the welding joint need to be strictly controlled. At present, the equipment is mostly provided with small-diameter pipes, and the butt joint welding is generally compared manually by a plumber and is difficult to align accurately; two-person operation is needed to accurately control the welding gap, which wastes time and labor. Considering efficiency and quality, a special tool can be adopted for aligning and controlling the gap, so that the production efficiency is greatly improved, and the labor cost is reduced.

Description of reference numerals: the upper clamping piece 1, the lower clamping piece 2, the loose-leaf ring 3, the elastic piece 4, the gap adjusting piece 5, the small clamping piece 6 and the upper and lower clamping piece spot welding windows 7.
Detailed Description
Name interpretation: the small-diameter pipe refers to a steel pipe with the diameter smaller than 30 cm.
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 and 2, the small-diameter pipe welding butt-joint device of the present invention comprises an upper clamping piece 1, a lower clamping piece 2, a loose-leaf ring 3, an elastic piece 4, a gap adjustment sheet 5, a small clamping piece 6, and an upper and a lower clamping piece spot welding windows 7. The front parts of the upper clamping piece 1 and the lower clamping piece 2 are arc-shaped, the rear parts of the upper clamping piece 1 and the lower clamping piece 2 are straight rods, the middle parts of the upper clamping piece 1 and the lower clamping piece 2 are connected through a loose-leaf ring 3, and the arc-shaped parts of the upper clamping piece 1 and the lower clamping piece 2 are provided with openings which are upper and lower clamping piece spot welding windows 7. After the connection, the arc shape of the front parts of the upper clamping piece 1 and the lower clamping piece 2 forms a cylinder, and a steel pipe to be welded can be held.
As shown in fig. 1 to 5, the rear side of the ring 3 of the present invention is provided with a spring plate 4, the spring plate 4 is preferably a high strength spring plate (made of 60Si2Mn spring steel plate), and the spring plate 4 is provided at the rear side of the ring 3 of the upper and lower clamping pieces 1 and 2. The high-strength elastic piece is adopted to clamp the first steel pipe and the second steel pipe, the first steel pipe and the second steel pipe are relatively fixed, the pipe orifices are aligned, the gap is accurate, and conditions are provided for accurate welding of the joint. The back side of the elastic sheet 4 is provided with a gap adjusting sheet 5, the gap adjusting sheet 5 is clamped and fixed through two small clamping sheets 6, and the adjusting sheet end of the gap adjusting sheet 5 penetrates through the elastic sheet 4, the loose-leaf ring 3 and extends out of the butt joint of the steel pipes to control the joint welding gap.
As shown in fig. 3 and 6, when butt welding small-diameter pipes, the specifications (thickness 1, 1.5, 2mm, etc.) of the gap adjustment sheet 5 are selected according to the pipe diameter and the welding process requirements, the gap adjustment sheet 5 is loaded into the butt welding device, the small clamping pieces 6 are clamped, then the clamping pieces of the butt welding device are pressed open by hands to clamp the butt welding joint of the first steel pipe and the second steel pipe of the equipment pipe distribution, the first steel pipe and the second steel pipe are automatically aligned to reduce the misalignment amount, then the first steel pipe and the second steel pipe gap adjustment sheet 5 are manually abutted, and the welding gap is controlled. And finally, spot welding can be carried out on the welding joint through the upper and lower clamping piece spot welding windows 7, and multiple spot welding positions of the aligning device can be rotated if necessary.
