According to the flaw detection device for the parts with the irregular detection surfaces, the problem of internal quality control after the inertia fatigue defect on a key part of an HXN5 locomotive rolling axial suspending tube is subjected to repair welding is solved, the defect of phi 1mm generated in a surfacing position in the repair welding process can be found, the welding quality is ensured, and a large quantity of cost is saved.
Description
Technical field
The utility model relates to the failure detector technical field, especially a kind of failure detector of test surface irregular part.
Background technology
(gear end and bearing end) respectively exists the tired district of two inertia, as easy as rolling off a log generation fatigue crack in the use to HXN5 locomotive rolling axle suspension bearing box at two ends.During locomotive inspection and repair,, will produce tremendous loss (every about 20,000 yuan), so crackle is carried out the measure that repair welding is a kind of economical rationality if the rolling axle suspension bearing box is scrapped because of these crackles.But because the influence and the irregular arc surface of test surface of crack site step, make that adopting UT (Ultrasonic Testing) to carry out welding Quality control becomes difficult point, conventional probe influenced by step can not to detect just the repair welding position (, and the greatest drawback yardstick that Φ 1mm(maintenance procedure requires is differentiated because of hypertelorism in optional inner headed face test surface position in the part) difficulty; Periphery step place is too near because of the distance surface, and the influence that overcomes the near field also is a difficult problem, so two available test surface flaw detections adopt conventional method all can not reach the purpose of detection, needs the new probe of design new technology to detect a flaw.
The utility model content
Can't satisfy the deficiency that flaw detection requires in order to overcome existing failure detector, the utility model provides a kind of failure detector of test surface irregular part.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of failure detector of test surface irregular part, and the bottom of inboard flaw detection probe is processed into circular-arc, and bottom one side of outside flaw detection probe is circular-arc, and opposite side is flat shape.
According to another embodiment of the present utility model, further comprise in described inboard flaw detection probe and the outside flaw detection probe being provided with wafer.
According to another embodiment of the present utility model, comprise that further described interior flaw detection probe inspection frequency adopts 3MHZ – 5MHZ frequency.
According to another embodiment of the present utility model, further comprise the best 4MHZ of being of described interior its inspection frequency of flaw detection probe.
According to another embodiment of the present utility model, comprise that further described inboard flaw detection probe and its surface of outside flaw detection probe are the organic glass manufacturing.
The beneficial effects of the utility model are, the failure detector of this test surface irregular part, solved internal soundness control problem behind the tired defective repair welding of HXN5 locomotive rolling axle suspension bearing box key position inertia, can find the defective of the Φ 1mm that the built-up welding position produces in the repair welding process, guaranteed welding quality, this technology has been successfully applied to HXN5 locomotive axle suspension bearing box repair welding and has handled the saving great amount of cost at present.

Embodiment
As Fig. 1 is structural representation of the present utility model, a kind of failure detector of test surface irregular part, and the bottom of inboard flaw detection probe 3 is processed into circular-arc, and bottom one side of outside flaw detection probe 4 is circular-arc, and opposite side is flat shape.
According to another embodiment of the present utility model, further comprise in described inboard flaw detection probe 3 and the outside flaw detection probe 4 being provided with wafer.
According to another embodiment of the present utility model, comprise that further described interior flaw detection probe 3 inspection frequencies adopt 3MHZ – 5MHZ frequency.
According to another embodiment of the present utility model, further comprise the best 4MHZ of being of described interior flaw detection probe 3 its inspection frequencies.
According to another embodiment of the present utility model, comprise that further described inboard flaw detection probe 3 and outside flaw detection probe 4 its surfaces are the organic glass manufacturing.
The failure detector of this test surface irregular part is in to the flaw detection of axle suspension bearing box 1 inner headed face, adopt 4P6 * 6FG30 double-crystal normal probe, inboard flaw detection probe 3 is square, the organic glass surface working becomes the circular arc of coincideing with axle suspension bearing box 1 inner headed face, and two wafer 5 relative positions are axially consistent with axle suspension bearing box 1; In externally disc flaw detection, adopt 4P6 * 6FG5 double-crystal normal probe, outside flaw detection probe 4 is square, and the organic glass surface working becomes the arc that coincide with axle suspension bearing box 1 periphery arc transition place, and two wafer relative positions are axially consistent with axle suspension bearing box 1.
The failure detector of this test surface irregular part substitutes the circular double crystal probe that uses traditionally with square double crystal probe, solve irregular surface coupling stability problem, avoided wafer 5 relative positions to change the interference problem of the irregular surface waveform transformation that causes simultaneously; Inner headed face flaw detection overcomes the lack of resolution problem by selecting the 4MHz frequency, simultaneously by verification experimental verification selected wafer 5 sizes can guarantee the problem of far field detection energy; The periphery flaw detection has solved the step interference problem, the selection of short focal length has guaranteed 1mm ~ 10mm scope is covered, cylindrical circular arc and fillet circular arc both direction guarantee that identical is the difficult point that probe is made simultaneously, the cooperation of probe wafer 5 sizes and frequency can be differentiated the defective of near field Φ 1mm, has guaranteed the quality of repair welding.
