Abstract

The invention discloses a rotary welding device, comprising a frame as well as a drive component and a rotary component which are fixed on the frame. The rotary welding device is characterized in that the rotary component comprises a fixed disk fixed on the frame and a rotary disk rotationally installed on the fixed disk; the fixed disk is also equipped with a support rolling device which comprises a riding wheel rotationally installed on the fixed disk; and the riding wheel is positioned between the fixed disk and the rotary disk and is matched with the rotary disk. The rotary disk is provided with a soft steel wire clamping slot on which a soft steel wire rope is sleeved, and two ends of the soft steel wire rope are respectively connected with the drive component. The rotary welding device disclosed by the invention is reasonable in design and reliable in performance, ensures that the rotary disk can rotate more flexibly in a more balanceable mode when loading the rotation of a large-sized workpiece, can obtain good welding quality, has high work efficiency, lightens labor intensity of workers, and is convenient and safe in operation and maintenance.

Description

Technical field [0001] The invention relates to a welding device, in particular to a rotary welding device suitable for automatic welding of large circumferential workpieces. Background technique [0002] The stator shell of the wind turbine needs to be welded with 8 welds. Each weld has a diameter of 5-6 meters and a circumference of about 18 meters. The height of the weld from the ground is within 0.2 to 0.5 meters. Within 0.5 meters, the prior art mostly adopts manual welding technology. Workers can only squat or sit while welding. The welding movement range is small, and the swing distance of the hand is short. During the movement, the hand is unstable. The welding requires 45° fillet welding. When the seam is actually welded, the bottom is wide and the top is narrow, resulting in many welded joints and uneven weld formation, which cannot meet the ideal welding effect. [0003] The application number is 200910071013.7, and the Chinese invention patent named "Welding Rotary Mac...
