Abstract

The invention discloses automatic welding equipment for the inner wall of a pipeline. The automatic welding equipment comprises a supporting base, a welding gun, a welding gun moving device used for adjusting the position and posture of the welding gun, a pipeline preheating device used for preheating a welding area and a workpiece positioning tool used for fixing a to-be-welded workpiece to the inner wall of the to-be-welded pipeline; and the welding gun moving device comprises a welding gun connecting rod used for being connected with a welding gun, a straight moving mechanism used for enabling the welding gun to horizontally move in the length direction of the to-be-welded pipeline, a rotary moving mechanism used for enabling the welding gun to rotate on the cross section of the to-be-welded pipeline, and an inclination angle adjusting mechanism used for adjusting the inclination angle between the welding gun and the inner wall of the to-be-welded pipeline. According to the automatic welding equipment, operation such as positioning, pressing, preheating, spot welding and welding can be conducted in the pipeline, and automatic welding of the workpiece on the inner wall of the pipeline with the inner diameter ranging from 50 mm to 200 mm is achieved.

Description

technical field

[0001] The invention relates to a welding device, in particular to an automatic welding device for the inner wall of a pipeline. Background technique

[0002] Most of the existing automatic welding equipment is aimed at the external welding of structural parts, and generally cannot perform welding operations on the inner wall of narrow pipes; and usually does not have a preheating function, which cannot meet the needs of special welding processes for preheating of the welding area; at the same time, during the When welding inside the pipeline, due to the narrow space, it is difficult to effectively fix the weldment by manual operation, which affects the quality of subsequent welding. Contents of the invention

[0003] The purpose of the present invention is to provide an automatic welding equipment for the inner wall of a pipeline, which can meet the welding operation of the inner wall of a narrow pipeline.

[0004] In order to achieve the above object, th...
