Auxiliary welding device for tap water pipe

Abstract

The invention relates to the field of pipeline welding, in particular to an auxiliary welding device for a tap water pipe. The device comprises a base plate, a pipeline clamping device, a pipeline feeding device, an auxiliary feeding device and an auxiliary welding device; the auxiliary feeding device comprises two auxiliary mechanical arms used for making pipelines aligned with one another, the auxiliary mechanical arms are fixedly installed on the base plate, the pipeline clamping device is arranged between the two auxiliary mechanical arms and fixedly installed on the base plate, and the auxiliary welding device is fixedly installed on the base plate and located at one side of the pipeline clamping device; the auxiliary welding device is provided with grinding equipment used for grinding the end faces of the pipelines and hot-melting equipment used for conducting hot-melting on the end faces of the pipelines, the pipeline feeding device comprises two feeding mechanical arms used forpipeline feeding, and each feeding mechanical arm is arranged at the end, away from the pipeline clamping device, of the corresponding auxiliary mechanical arm. The problems that during welding, buttjoint of the pipelines is difficult, and fixing is difficult after butt joint is completed are solved, and the operation difficulty of workers is lowered.

Description

technical field [0001] The invention relates to the field of pipe welding, in particular to a welding auxiliary device for water pipes. Background technique [0002] The tap water pipe is the pipe used to deliver tap water to the user. The tap water pipe is responsible for transporting water. The composition of a tap water pipe needs to be welded together by multiple water pipes. The water pipes are welded on site. When welding the front and rear water pipes, since the welding part is in the shape of a ring, the welding torch needs to be adjusted at any time during the welding process. The existence of tap water pressure puts forward higher requirements on the welding department. Tap water pipe welding is generally divided into two types, one is torch welding, and the other is hot melt welding.
