The invention relates to a cleaning head, in particular to a cleaning head structure for numerical control high-pressure water jet flow burring. The cleaning head structure comprises a longitudinal connecting plate and a transverse bearing plate, a high-pressure rotator, a synchronous belt, a taper sleeve synchronous pulley, a synchronous pulley, a water passing body and a servo motor are arranged on the transverse bearing plate, the servo motor is fixed onto the transverse bearing plate, an output end of the servo motor is connected with the synchronous pulley, one end of the high-pressure rotator is connected with the longitudinal connecting plate through an 'L'-shaped support, the other end of the high-pressure rotator is connected with the taper sleeve synchronous pulley through a flange, one end of the water passing body is coupled with the taper sleeve synchronous pulley, the other end of the water passing body is connected with a hexahedral rotating tower, and a spray bar is arranged on each surface of the hexahedral rotating tower. The cleaning head structure is simple, low in cost, easy to seal, convenient to maintain, high in cleaning quality and particularly applicable to cleaning and burring of precision machinery parts.
