Novel segmented stator iron core circle-splicing welding machine and welding method thereof

The invention relates to the technical field of stator iron core machining and welding, and discloses a novel partitioned stator iron core circle-splicing welding machine and a welding method thereof.The novel partitioned stator iron core circle-splicing welding machine comprises a positioning and clamping mechanism, and the positioning and clamping mechanism further comprises a mounting disc. According to the characteristic that the rotating angles of the control drawstrings on the outer wall of the tightening wheel are equal, a U-shaped rod and a pushing plate are arranged in the equipment, when the equipment completes filling, a power source of a power motor is switched on, an output shaft tightens the control drawstrings on the periphery through the tightening wheel, and the multiple control drawstrings drive a rotating plate at the other end and the U-shaped rod to move synchronously; the U-shaped rod moves towards the center of the equipment along the inner wall of the sliding-out electric frame, at the
