Abstract
The utility model relates to a welding device, especially to a symmetrical spring type tank gland inner ring welding device. The device comprises a central positioning shaft where the center is fixed, a front three-pawl positioner, a back three-pawl positioner and a gas protective welding frame. The gas protective welding frame is disposed at the top of the central positioning frame and is connected with the central positioning frame through a bearing. A 60-degree phase position lies between the two three-pawl positioners. Each three-pawl positioned comprises three equilong positioning pawls at intervals of 20 degrees, and a central positioning clip disposed at the center of the positioning pawls. The central positioning clip is fixedly connected with the central positioning shaft. The gas protective welding frame comprises a frame rod, a balancing weight disposed at one end of the frame rod, and a welding head with a protective cover at the other end of the frame rod. The structure of the welding device ensures concentricity of the central positioning shaft and the tank, so as to ensure welding quality, allow a return device to be fixedly connected with the gas protective cover, effectively overcome problems of non-uniform stress and gas leakage as well as gas protection failure caused by cylindrical shell permiting out-of-roundness, and effectively improve welding efficiency.
