Abstract

The utility model discloses a hollow rotating mechanism for welding, which comprises a fixed casing. A power gear is arranged on the fixed casing and is connected with a motor and a reduction gearbox; a rotating gear ring is movably connected onto the fixed casing and is mutually meshed with the power gear; a rotating support body is fixed on the rotating gear ring; and an actuator is arranged on the rotating support body. When the hollow rotating mechanism is in use, a welding head or other tools are fixed on the actuator on the rotating support body; a television is opened, and a power supply for the welding head or the other tools is turned on simultaneously; the power gear drives a rotating support ring to rotate and simultaneously drives the rotating support body fixed on the rotating support ring to synchronously rotate, thereby driving the actuator to carry out circumferential motion around a central shaft at the hollow part of the rotating support body. The hollow rotating mechanism has a compact structure and has the advantages of improving the welding quality and the production efficiency, reducing the labor intensity, and reducing the cost. The utility model is particularly suitable for carrying out hollow circumferential welding or other working procedures in upper air and narrow spaces.
