Hump pipe positioning device

The invention discloses a hump pipe positioning device. A positioning module and a supporting module are arranged on a base. A supporting disc of the positioning module is provided with a plurality ofprofiling blocks capable of sliding in the radial direction of the supporting disc, and the peripheral arc surfaces of the profiling blocks are provided with protruding parts outwards. The center ofthe supporting disc is provided with a main shaft connected with the profiling blocks, the main shaft is connected with an air cylinder, and the air cylinder drives the main shaft to rotate. When theprofiling blocks of the hump pipe positioning device are used for positioning a hump pipe, the protruding parts integrally fill the humps of the hump pipe, the outer surfaces of the protruding parts make contact with the corresponding inner surfaces of the humps, and circumferential positioning and axial positioning of the hump pipe are achieved. Due to the fact that when the profiling blocks areused for positioning, the ou
