Intelligent metal material nondestructive testing equipment

The utility model discloses intelligent metal material nondestructive testing equipment which comprises an installation frame, clamping plates, a connecting unit, an installation block, a transmission assembly, a piston cavity, an air inlet pipe, a connecting mechanism, a telescopic part, a piston block and a driving assembly. The driving assembly drives the transmission assembly, the connecting unit and the connecting mechanism which are connected with the driving assembly to operate, the connecting unit drives the telescopic component to rotate, the telescopic component rotates to drive the metal piece to rotate slowly, so that the detection probe detects multiple positions of the metal piece, and the transmission assembly drives the mounting block to intermittently move towards the other end of the metal piece. The connecting mechanism drives the installed piston block to slide in a piston cavity in a reciprocating mode in the process, the piston block conveys air in the piston cavity to the spray head thr
