The invention relates to an ultrasonic flaw detection
system for automatically detecting an
airplane hub. The ultrasonic flaw detection
system comprises a plurality of idler wheels, a plurality of supporting rods, a
workbench, a power supply, a control device, a display screen, a fixing tray, a rotator, a first motor, a screw rod, a second motor, a
mobile station, two connecting shafts, a fixing plate, a stretching arm, a spraying device, an ultrasonic probe, a third motor and a rotating shaft. The ultrasonic flaw detection
system for automatically detecting the
airplane hub has the advantages that the
free movement of the ultrasonic probe on upper, lower, left and right directions at 360 degrees in the space is realized through the movement of the rotator, the screw rod, the
mobile station and the stretching arm and the driving of the motor; an all-dimensional multilayer stereoscopic automatic detecting structure is really formed; the system can be moved through the idler wheels according to different occasions, so that a detected part can be detected by the system in the optimal working position; and the spraying device and the ultrasonic probe can be flexibly converted and used through the rotating shaft and the circular
work flow of firstly spraying a
coupling agent and then using the probe for detecting is realized, so that the spraying and detecting integration is realized.
