Abstract

The invention relates to the technical field of welding automation and provides an automatic welding device for an end flange of a pipefitting. The device comprises a pipefitting rotating unit, a flange supporting unit and a welding gun operating unit. The pipefitting rotating unit is arranged in the middle of a base for clamping and rotatably driving the pipefitting to be welded, and a rack is provided with a centering and clamping driving mechanism for driving a lower roller set and an upper roller set to move synchronously and reversely; the flange supporting unit is arranged at a longitudinal outer end of the base for clamping the flange to be welded and comprises a movable seat and a chuck, and the base is provided with a linear power part for driving the movable seat to move longitudinally; and the welding gun operating unit is arranged on the outer side of the base for moving the automatic welding gun. The automatic welding device for the end flange of the pipefitting can realize clamping, abutting and automatic welding operations of the pipefittings with different lengths and outer diameters to flanges, so that the device is easy to operate, high in degree of automation andsuitable for being applied to operational occasions of welding the pipefittings to the flanges.

Description

technical field [0001] The invention relates to the technical field of welding automation, in particular to an automatic welding equipment for welding the circular welds between pipe fitting ends and flanges. Background technique [0002] The flange connection at the end of the pipe fittings has the characteristics of easy disassembly, which is suitable for the connection of multiple disassembly connections. In the manufacturing plant, the pipe fittings and flanges are mostly welded. Due to the lack of special welding machines, the pipe fittings are generally placed on the ground. Align and press the pipe fittings and flanges with manual clamps on the upper or supporting platform. When the pipe fittings and flanges are in a static state, the welding worker holds an automatic welding torch to fix the pipe fittings and flanges by spot welding, and then assembles and disassembles the fixtures. The hand-held automatic welding torch is used to complete the welding of the circular...
