Embodiment Construction
[0013] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments:
[0014] Such as figure 1 As shown, the steel pipe butt welding positioning bracket includes an upper positioning mechanism 1, a lower positioning mechanism 2 and a welding mechanism 3. The upper positioning mechanism 1 and the lower positioning mechanism 2 have the same structure and both include a tube positioning channel 4, a cylinder 5 and a positioning rod 6. The upper positioning mechanism 1 and the lower positioning mechanism 2 are provided with a tube positioning channel 4 along the vertical direction, and a cavity is opened on the outside of the tube positioning channel 4, and a sliding plate 7 adapted to it is placed in the cavity. , The sliding plate 7 is connected to the cylinder 5 through a connecting rod, a plurality of through holes are horizontally opened on the wall between the cavity and the tube positioning channel 4, and a positioni...

The invention discloses a butt welding positioning bracket for steel pipes. The butt welding positioning bracket comprises an upper positioning mechanism, a lower positioning mechanism and a welding mechanism, wherein the upper positioning mechanism and the lower positioning mechanism are of the same structure and respectively comprise pipe positioning channels, air cylinders and positioning rods, the pipe positioning channels are vertically formed in the upper positioning mechanism and the lower positioning mechanism, cavities are formed in the outer sides of the pipe positioning channels, sliding plates which are matched with the cavities are placed in the cavities, the sliding plates are connected with the air cylinders by virtue of connecting rods, a plurality of through holes are horizontally formed in walls between the cavities and the pipe positioning channels, the positioning rods are placed in the through holes, the positioning rods are fixed to the sliding plates, and the welding mechanism is arranged between the upper positioning mechanism and the lower positioning mechanism. By adopting the technical scheme, the butt welding positioning bracket has the beneficial effects that the steel pipes can be accurately positioned, and the welding is difficult to deform.
Description
Technical field [0001] The invention relates to the technical field of welding, in particular to a steel pipe butt welding positioning bracket. Background technique [0002] When welding steel pipes, especially slender steel pipes, the steel pipe is placed horizontally between the common steel pipe positioning, which is often prone to deformation due to its own weight, and the welding is carried out by rolling the steel pipe during welding, and alignment is more likely to occur when rolling. Not precise. For this reason, the present invention proposes a new type of steel pipe butt welding positioning bracket, which is more practical, perfect and convenient to solve the above problems. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a butt welding positioning bracket for steel pipes, which can be used to weld steel pipes to accurately locate the steel pipes, and the welding is not easy to deform. [0004] In order to solve...
