Rotation structure of heat transfer pipe positioning robot

The invention discloses a heat transfer pipe positioning robot rotating structure which comprises a base and a rotary table, and the base and the rotary table rotate relatively to achieve the rotating action. The positioning robot has the beneficial effects that a gas path and a circuit conversion mechanism slip ring are realized and are integrated into a positioning robot structure, so that an electric signal and one path of compressed gas are not limited by a cable and a gas pipe, and infinite circulating rotation can be realized. And the inspection efficiency can be greatly improved. Due to the structure of the sliding ring, valves, sensors and the like of the rotary table are all arranged in front of a clamping jaw of an executing mechanism, and therefore air pipe connection can be reduced. Due to the fact that the eccentric motor is adopted to drive the synchronous belt wheel, the overall height of the device is reduced, and space is reserved for installation of the sliding ring.
