Fixing device for steel pipe welding

Abstract

The invention discloses a fixing device for steel pipe welding. The fixing device comprises an installation seat provided with an installation groove at the bottom, a set of installation plate is vertically welded at the top of the installation seat, a fixed plate is welded at the top of the installation plate, a gas storage bottle is placed at the top of the fixed plate, a U-shaped guide rod is welded at the bottom of the fixed plate, a hollow sliding block is connected to the outer side of the U-shaped guide rod in a sleeving sliding mode, and a welding main body is fixed at the bottom of the hollow sliding block through screws. By arranging the welding main body, locking screws, the U-shaped guide rod, the hollow sliding block, a double-end motor, a rotational rod, a belt wheel, a beltwheel ring and an installation pipe, holding the welding main body with a hand to weld is not required, the fixing device is very labor-saving, as a to-be-welded pipe is rotational, the to-be-welded pipe is uniformly welded during welding, the quality is good, the welding main body can slide in position according to requirement, so that the welding operation is convenient, the operation is simple,the use is flexible and convenient, and therefore, the fixing device is suitable for popularization and use.

Description

technical field [0001] The invention relates to the technical field of welding devices, in particular to a fixing device for steel pipe welding. Background technique [0002] A steel pipe is a steel material with a hollow section whose length is much greater than its diameter or circumference. According to the cross-sectional shape, it is divided into circular, square, rectangular and special-shaped steel pipes; according to the material, it is divided into carbon structural steel pipes, low alloy structural steel pipes, alloy steel pipes and composite steel pipes; Steel pipes for thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high-pressure equipment, etc.; according to the production process, they are divided into seamless steel pipes and welded steel pipes, among which seamless steel pipes are divided into hot-rolled and cold-rolled (drawn) Two kinds, welded steel pipe is divided into straight seam welded steel pipe and spiral sea...

AI Technical Summary

Problems solved by technology

[0003] At present, when processing steel pipes, it is often seen that workers hold welding devices to weld and butt steel pipes. It is very troublesome and laborious to weld and butt steel pipes in a hand-held manner. At the same time, after the existing welding devices fix the steel pipes, the steel pipes It does not move, so that when welding butt joints, the welding of steel pipes is uneven, the welding quality is poor, and the use effect is not good enough, which needs to be improved
