The utility model has the characteristics that ultrasonic wave depends on a working outer wall to carry out refraction; the special inclined probe has small sound loss, large detection range, accuracy and high efficiency.
Description
The utility model relates to a kind of circumferentially angle probe of flaw detection of round piece that is used for, the angle probe of particularly a kind of railway wheel and rim flaw detection.
At present, adopt single-chip or twin lamella for the round piece used angle probe of circumferentially detecting a flaw, ripple of the no end produces more, and ultrasound wave is done the motion of " v " type between workpiece outer wall and inwall, sound decreases big back and forth, investigative range is little need to move a week by probe, particularly for the flaw detection of the wheel of train headstock, owing to there is brake shoe to block, need motor-car 3-10 times, waste time and energy, dangerous, the probability of omission, erroneous judgement is also very big, has had a strong impact on the transportation safety of railway.
The purpose of this utility model is: provide a kind of circumferential flaw detection special-purpose angle probe, it has the angle probe of ripple at the bottom of polycrystalline sheet, multi-angle, the band, rely on the outer wall of workpiece that ultrasound wave is reflected, sound decreases little, make it in the flaw detection process, reduce the moving range of probe, need both forward and reverse directions on a bit of distance carries out twice detection can be finished.Can improve detection accuracy, stop the artificial spy of leaking, erroneous judgement receives, produces end ripple simultaneously, realizes purpose accurately and efficiently by polycrystalline sheet multi-angle, emission simultaneously.
The utility model special-purpose angle probe of circumferentially detecting a flaw, it is made up of shell, voussoir, wafer, telefault, lead-in wire, binding post and inserts etc.; Wherein wafer adopts polycrystalline sheet multi-angle, the quantity of wafer and angle are according to the flaw detection thickness of workpiece, diameter and decide, minimum is four wafers, be fixed on the both sides of triangle voussoir, wherein a side is a plurality of main transmitting-receiving wafers, its angular distribution is divided into and the identical some equal portions of main transmitting-receiving number of wafers for the flaw detection thickness with workpiece, each main transmitting-receiving wafer adopts different angles corresponding respectively with it, opposite side is driven wafer, do not add the energy electric pulse, wherein an angle of leading the transmitting-receiving wafer is identical with opposite side for the angle of this driven wafer.Wherein telefault is connected with main transmitting-receiving wafer by lead-in wire, and the lead-in wire other end is fixed on the binding post.Main transmitting-receiving wafer sends ultrasound wave, after reflecting a week by the workpiece outer wall, receive by driven wafer, driven wafer vibration is sent ultrasound wave and is reflected to main transmitting-receiving wafer through voussoir, produces end ripple, and main in addition transmitting-receiving wafer emission ultrasound wave is refracted to driven wafer through voussoir, after driven wafer vibration generation ultrasound wave reflects a week along the workpiece outer wall, being received by main transmitting-receiving wafer also is end ripple, energy a little less than, twice transmitting-receiving strengthened end ripple with sound path.
The utility model has the advantages that: owing to rely on outer wall to reflect, the circular outer wall of workpiece has the effect of gathering to ultrasound wave, sound decreases little, correspondingly prolonged detection range, the polycrystalline sheet, multi-angle, band end ripple, the precision height, save time, laborsaving, usually the flaw detection to train wheel needs probe is moved a week, particularly the flaw detection to the wheel of train headstock needs motor-car 3-10 times, more than 2 hour time, use the utility model only need on workpiece, to move one of them a half-distance of long sound path survey about 20 minutes, need not motor-car, quick and precisely, and because band end ripple, can make the staff know the duty of instrument and probe, and can find out the position of wound exactly.
The utlity model has following accompanying drawing:
Fig. 1, the utility model sectional view
Fig. 2, the utility model vertical view
Number in the figure:
1, shell 2, driven wafer 3, main transmitting-receiving wafer
4, inserts 5, telefault 6, voussoir
7, lead-in wire 8, binding post
Now for embodiment and be described with reference to the accompanying drawings as follows:
With the flaw detection tire thickness is that the train wheel of 75mm, diameter 1050mm is an example, see also Fig. 1, shown in Figure 2, the utility model special-purpose angle probe of circumferentially detecting a flaw, it is that (wherein three is main transmitting-receiving wafer 3 by shell 1 voussoir 6, wafer, another piece is driven wafer 2, can not add the energy electric pulse), diameter and flaw detection thickness according to this workpiece, and the velocity of sound 3240m/s of the velocity of sound 2730m/s workpiece of voussoir, the angle [alpha] that can calculate three main transmitting-receiving wafers 3 are respectively 41 ° 9 ', 39 ° 1 ', 36 ° 9 ' and the angle beta of driven wafer 2 is decided to be 39 ° 1 '.With telefault 5, by 7 and three main transmitting-receiving wafer 3 welding of lead-in wire, 7 other ends that go between are fixed on the binding post 8, three main transmitting-receiving wafers 3 and driven wafer 2 are bonded at the both sides of triangle voussoir 6, the position of corresponding main transmitting-receiving wafer 3 solder joints on voussoir 6 wherein respectively, and pre-pit makes main transmitting-receiving wafer 3 cooperate closely with voussoir 6.The voussoir 6 that will glue wafer again is stuck on the shell 1 with inserts 4 that voussoir 6 is fixing.
During flaw detection, the binding post 8 of probe is connected with defectoscope, probe is placed on the tire tread, the sand paper mill is several down on the pad, probe and periphery are coupled, brushing couplant surveys, to one of a side shifting a half-distance of long sound path be 250mm, turn round 180 ° and back move to initial point again, can avoid occurring the blind area, half of each detection rim had ripple flaw echo to occur just being before end ripple behind the beginning ripple on the instrument screen, can accurately find out the injury of workpiece according to the position relation of flaw echo and beginning ripple and end ripple.If there is not end ripple to occur, then instrument and probe have problem, can make the staff know the duty of instrument and probe.
