The technical field of train wheel hub flaw detection and detection device, in particular, a train wheel hub flaw detection and detection device, comprising a carrier, a support rod, an ultrasonic detection control device, a detection mechanism, and a train wheel. A detection mechanism is set just above the train wheel, an ultrasonic detection control device is set on the upper end of the detection mechanism, and two sets of support rods are symmetrically set at the lower end of the detection mechanism; under the guidance of the rail, the train wheel is rolled into the rotating mechanism, and then the cylinder pulls the pressure plate, and the pressure plate pushes The guide post moves downward, and the probe carrier is pushed vertically under the cooperation of the guide post and the upright bearing, so that the probe carrier is just sleeved on the train wheel, and the rotating mechanism runs at the same time. Multi-directional flaw detection

The basic shape of the shell of the probe is a rectangular shell; the first wafer group is bonded and fixed on the upper end face of the first delay block to form the first transmitting and receiving assembly, and the second wafer group is bonded and fixed on the second delay block The second transmitting and receiving assembly is formed on the upper end face of the first chip group; the first transmitting and receiving assembly and the second transmitting and receiving assembly are fixed and bonded to the shell through the block of sound-absorbing material; the transmitting and receiving surface of the piezoelectric chip of the first wafer group faces downward Set on the left, the transmitting and receiving surface of the piezoelectric chip of the second wafer group is set downward and rightward; the degree α of the acute dihedral angle formed by the plane where the end face of the piezoelectric chip is placed and the plane where the lower end face of the probe is located is the degree α of 20 degrees to 78 degrees; the shape of the lower end face of the entire probe is a circular arc surface corresponding to the radial outer peripheral arc surface of the tire to be tested. When the probe is used, the detection is accurate, time-saving and labor-saving
