Abstract

The invention relates to the technical field of welding, and provides a steel pipe flange welding and positioning device. The steel pipe flange welding and positioning device comprises a first sliding rail, a first platform and a second platform, wherein the first platform and the second platform are arranged on the first sliding rail in a sliding mode. Limiting devices are arranged between the first platform and the first sliding rail and between the second platform and the first sliding rail. A first fixing jaw and a second fixing jaw which are used for positioning flanges are connected to the first platform and the second platform in a relatively rotating mode, and at least one of the first fixing jaw and the second fixing jaw is driven by a power device to rotate. Roller carriers used for holding steel pipes are arranged at the positions, between the first fixing jaw and the second fixing jaw, of the first platform and the second platform, and the height of the roller carriers is adjustable. The device is ingenious in structural design, is particularly suitable for positioning of steel pipes of various diameters and flanges of various diameters, and can achieve stable welding and guarantee the welding quantity; the steel pipes and the flanges can be positioned conveniently. In addition, the device is simple in structure, low in cost and easy to popularize.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a steel pipe flange welding device. Background technique [0002] Common transportation pipelines are usually spliced ​​by a large number of steel pipes. Both ends of each steel pipe are welded with flanges, and the steel pipes are connected by flanges. The flange connection is convenient, firm and tight, so it is called Widely used in the connection of steel pipes. [0003] Both the steel pipe and the flange are processed separately, and the flange is welded to both ends of the steel pipe when necessary. At present, the welding of steel pipes and flanges is mostly done by manual welding. Since a large number of steel pipes are used in the transportation pipeline, the labor intensity of manual welding is very huge, and because of the heavy weight of the steel pipes, it cannot be conveniently connected with the method. The flange is used for positioning, and the welding personn...
