Abstract
The invention relates to an ultrasonic flaw detector, specifically relates to an ultrasonic flaw detector for a railway wagon bearing outer rings, and belongs to the field of bearing flaw detection equipment. The rotation of the bearing out ring drives a probe frame to move vertically through drive of a direct current DC adjustable-speed motor and through gear transmission. An result of resultant motion of the bearing outer ring and the probe can make the probe generate a spiral rising movement motion track on the surface of the bearing outer ring, so that continuity of the detection is guaranteed and transmission is simplified. The driven frames have two ultrasonic probes respectively controlled by two ultrasonic flaw detectors, so that the ring-shaped groove in the middle of the bearing outer ring can be free of detection and flaw detection efficiency can be increased. Space between the two driven frames can be adjusted through forward and reverse screws connected with the driven frames, so as to meet application requirements of different products. In the structural design, the probe does not move vertically but only the bearing outer ring does a horizontal rotation motion in a first lap and a last lap of the bearing outer ring, so that flaw detection blind areas of the first lap and the last lap are covered and an object of full coverage is achieved.
Description
Technical field
The present invention relates to a kind of ultrasonic flaw-detecting machine, specifically relate to a kind of railway truck bearing outer ring ultrasonic flaw-detecting machine, it belongs to bearing flaw detection apparatus field.
Background technology
Along with the development of industry, corresponding every profession and trade to the requirement of bearing also in continuous raising.Particularly railway bearing, wind-power electricity generation bearing, military products bearing and extraordinary high-accuracy bearing accuracy class requirement constantly promote, and require stricter especially to the inherent liver mass of bearing ring.At present, the bearing outer ring of railway freight-car organizes crack detection technology generally to adopt magnetic powder inspection, but there is the problem of the deficiency to profound level flaw detection in magnetic powder inspection, thus occurred outer ring fatigue phenomenon when causing railway freight-car to run, and has a strong impact on the operation of railway freight-car.
Summary of the invention

To achieve these goals, the technical solution adopted in the present invention is bearing outer ring ultrasonic flaw-detecting machine, and it comprises: body, DC speed-regulating motor, coupling liquid device and pump; Organism bottom is equipped with coupling liquid device, and coupling liquid device is connected with DC speed-regulating motor by pump; Its spy is: DC speed-regulating motor is connected with driving gear, and driving gear is meshed with follower gear; Follower gear drives initiatively frame to move up and down by the transmission nut be arranged in active frame, initiatively frame is provided with spring base, spring is provided with in spring base, initiatively frame drives first to move from moving frame and second from moving frame, first is provided with forward and reverse screw rod from moving frame and second between moving frame, and described first is provided with buting iron from moving frame two ends; First is provided with the first probe from moving frame, second is provided with the second probe from moving frame, and the first probe is controlled by the first defectoscope, and the second probe is controlled by the second defectoscope, first defectoscope and the second defectoscope are installed on web joint, and web joint is connected with screw mandrel.
Described spring base upper surface and second is provided with gap between moving frame lower surface.
Described clearance distance is 4mm.
Described forward and reverse screw rod regulates first from moving frame and second from the distance between moving frame.
Be respectively equipped with two little springs after described first probe and the second probe, the first probe and the second probe are contacted with bearing outer ring always.
The course of work of the present invention is: first by regulating the forward and reverse screw rod be connected from moving frame with second from moving frame with first to adjust first from moving frame and second from the line space of moving frame; Starting switch, DC speed-regulating motor driving bearing outer ring rotates, and by power transmission to driving gear, driving gear by power transmission to follower gear, follower gear moves on driving and starting built with the active frame of transmission nut, the upper surface of the spring base initiatively on frame and leave the gap of a 4mm from the lower surface of moving frame, first does not do vertical movement from moving frame and second from moving frame, because the wafer of probe is 5mm, formation width on bearing outer ring outside surface of popping one's head in is the horizontal annular flaw detection band of 5mm; Contacting of upper surface when spring base and the lower surface from moving frame, spring base promotes first and moves from moving frame from moving frame and second, pops one's head in form the helical annular flaw detection band that a pitch is 4mm on bearing outer ring outside surface; After buting iron encounters web joint, first stops moving from moving frame and second from moving frame, first probe and the second probe do not do vertical movement, bearing outer ring continues to rotate under the driving of buncher, by main drive gear and follower gear by power transmission to screw mandrel, initiatively frame moves on the driving lower compression spring of leading screw continues, and the first probe and the second probe again form horizontal annular flaw detection and be with on bearing outer ring outside surface, encounter second switch until hit iron and stop, completing a working cycle; Downstream position got to by hand-held button, motor reversal, and defectoscope is oppositely detected a flaw.
The invention has the advantages that: bearing outer ring is rotated through DC speed-regulating motor and drives and drive probe holder to do vertical movement by gear drive; Bearing outer ring and the result of probe resultant motion make probe create a helix on bearing outer ring surface to rise the movement locus of movement, ensure that the continuity of detecting, transmission is simplified.With two ultrasonic probes moving frame, controlled by two ultra-sonic defect detectors respectively, can accomplish to annular groove in the middle part of bearing outer ring exempt from visit, flaw detection efficiency can be improved again.Two are carried out spacing adjustment from moving frame by the forward and reverse screw rod be connected with it, to meet different product request for utilization.Structural design makes bearing outer ring when turning first lap and the last circle, pop one's head in not for vertical movement, just bearing outer ring does horizontal revolving motion, thus the flaw detection blind area of first lap and most end circle is covered, and reaches all standing flaw detection object.
