Abstract
The utility model relates to an ultrasonic flaw-detecting machine, in particular relates to an ultrasonic flaw-detecting machine for a bearing outer ring and belongs to the field of bearing flaw-detecting inspection equipment. The bearing outer ring is driven to rotate by virtue of a direct current speed regulating motor, and a probe frame is driven to vertically move by virtue of gear transmission; and a resultant movement result of the bearing outer ring and the probe causes the probe to produce a spiral line rising moving motion trail on the surface of the bearing outer ring, so that probing continuity is guaranteed and transmission is simplified. Each driven frame is provided with two ultrasonic probes which are respectively controlled by two ultrasonic flaw detectors, so that probing on an annular groove at the middle part of the bearing outer ring can be avoided and flaw deflection efficiency can also be improved.Two driven frames can carry out spacing adjustment by virtue of a forward screw and a reverse screw which are connected with the two driven frames, so as to meet operating requirements of different products. In structural design, the probe does not vertically move on a first circle and the last circle of the bearing outer ring and only the bearing outer ring does a horizontal rotational motion, so that flaw detection blind areas of the first circle and the last circle are covered, and the aim of all coverage flaw detection is achieved.
