Embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in Figure 1 and Figure 2, monocline probe of the present invention beam axis offset angle cubing: comprise the centering plate 11 and the dipping 12 that link together, centering plate 11 is provided with centering face 14, dipping 12 is dull and stereotyped and centering face 14 layout in 90 °, dipping 12 is provided with at least one measurement limit 13, the vertical line 15 of centering face 14 and measurement 13 one-tenth, limit angle α, the angle of angle α equals the offset angle of the beam axis maximum of qualified probe permission.
As shown in Figure 3, Figure 4, inspection sheet angle probe beam axis offset angle, except cubing 1, also needs test block 3.Probe 2 is transmitting ultrasonic wave acoustic beams and surveys echo, thereby detects the mechanism of test block 3 inherent vices.Centering plate 11 is for the mechanism with test block alignment, and during check, centering face 14 aligns with edge in test block 3, and dipping 12 is attached on test block front 33.Measuring limit 13 is the mechanisms for the angle at inspection sheet angle probe beam axis offset angle, and effect is the angle the α whether fleet angle of this probe 2 of contrast is less than vertical line 15 and measurement limit 13, thereby determines that whether probe 2 is qualified.
The acoustic beam of probe 2 transmittings is rectangle column acoustic beam, and the intensity of acoustic beam is outwards successively decreased by rectangular centre, can say, the acoustic beam of the probe 2 intensity maximums of sending is the acoustic beam on rectangle column axis, also claims the strongest acoustic beam 21.During measurement, need the strongest acoustic beam 21 over against test block end angle 31, now, will be at the highest wave amplitude of the oscillography screen display end corner reflection echo of defectoscope, when the highest ripple occurs, the reflection wave evaluation of angle, ultrasound wave opposite end or defect is the most accurately.Under perfect condition: when probe 2 emitting facet is during over against test block coboundary 32, the strongest acoustic beam 21 should be vertical with test block coboundary 32, the beam axis offset angle of popping one's head in is 0, now by adjusting the angle of probe chip 23, can in the side of the vertical line with test block front 33, adjust upward the incident angle of the strongest acoustic beam 21, make the strongest acoustic beam 21 over against test block end angle 31.But due to the defect in manufacture process, the strongest acoustic beam 21 might not have certain deviation angle conventionally over against test block coboundary 32, and the beam axis offset angle of popping one's head in is not 0.Described deviation angle has certain influence to 2 flaw detection effects of popping one's head in, so conventionally can stipulate a deviation angle value, pops one's head in 2 defective when deviation angle is greater than this value.
Cubing 1 detecting step is as follows successively:
A, as shown in Figure 5, probe 2 is placed in test block 3, and the 2 acoustic beam emitting facets that make to pop one's head in is over against test block coboundary 32;
The angle of B, adjustment probe 2 acoustic beam emitting facets and test block coboundary 32, and adjust probe chip 23 emission angles, find the highest wave amplitude of oscillography screen display end corner reflection echo, 2 the strongest acoustic beam 21 of now popping one's head in is over against test block end angle 31, i.e. position shown in Fig. 6;
C, as shown in Figure 7, after cubing 1 and test block 3 centerings, goes from 2 left and right sides of popping one's head in respectively by probe 2 with measuring limit 13, and the measurement limit 13 that leans against probe 2 both sides is symmetrical, now, measures limit 13 and pops one's head in and 2 there will be three kinds of situations:
A, as shown in Figure 8, measures limit 13 for one and fits together with probe 2 sidewalls, and another forms gaps 22 with probe 2 sidewalls, and 2 the offset angle of now popping one's head in equals the angle of angle α;
B, as shown in Figure 9, measures limits 13 for two and all forms gap 22 with probe 2 sidewalls, and gap 22 opening directions are identical, and 2 the offset angle of now popping one's head in is less than the angle of angle α;
C, as shown in Figure 7, measures limits 13 for two and all forms gap 22 with probe 2 sidewalls, and gap 22 opening directions are contrary, and 2 the offset angle of now popping one's head in is greater than the angle of angle α.
When to set monocline probe beam axis offset angle and be less than or equal to the angle of angle α be qualified, it is 2 qualified that above-mentioned a, two kinds of situations of b are popped one's head in; It is 2 defective that c situation is popped one's head in.
As shown in Figure 7, in figure, upwards, the opening direction in gap, right side is downward for the opening direction in gap 22, left side in described gap 22.
The beneficial effect of this programme is: use this cubing 1 can check fast the transmitting beam axis offset angle of probe 2 and the magnitude relationship between a certain angle definite value, thereby judge that fast whether this probe 2 is qualified, whole process is directly perceived, simply, judgement is clear can improve QC detection speed greatly.
According to 3.2.2.2.2 money requirement in standard JB4730.3-2005 < < bearing device Non-Destructive Testing > >, for ultrasound examination, with monocline probe beam axis offset angle, should not be greater than 2 °.So in the present embodiment: the angle of angle α is 2 °.
In the present embodiment: dipping 12 is isosceles trapezoids, the part that dipping 12 is connected with centering plate 11 is this trapezoidal bottom.In the detection method of mentioning, need to measure limit 13 above and from 2 left and right sides of popping one's head in, go by probe 2, and two measurement limits 13 are symmetrical.When cubing 1 is by centering plate 11 and test block 3 centerings, and from 2 two ends, left and right of popping one's head in by popping one's head in 2 o'clock, two waists of dipping 12 isosceles trapezoids just in time meet symmetrical requirement.
The beneficial effect of this programme is: if cubing 1 only has one to measure limit 13, and will align with probe 2 from 2 two ends, left and right of popping one's head in while detecting, the cubing 1 of need to overturning, makes to lean against the pop one's head in measurement limit 13 of 2 both sides symmetrical; And when dipping 12 is isosceles trapezoid, the cubing 1 that do not need to overturn, moves to probe 2 other ends, compare and can improve detection efficiency with the former.
The present invention uses cubing 1 to detect the relation of monocline probe beam axis offset angle and α, and operation steps is as follows:
A, probe 2 is lain in test block 3, and the 2 acoustic beam emitting facets that make to pop one's head in are over against test block coboundary 32;
B, adjust the angle of probe 2 acoustic beam emitting facets and test block coboundary 32, and adjust probe chip 23 emission angles, the strongest acoustic beam 21 of 2 transmittings that make to pop one's head in is over against test block end angle 31;
C, the side with the measurement limit 13 of cubing 1 from 2 the top probe 2 of a side of popping one's head in, obtain gap 22 opening directions of measuring limit 13 and probe 2 these sides formation, again with measuring the side of limit 13 from 2 top probe 2 opposite sides of opposite side of popping one's head in, and obtain and measure limit 13 and gap 22 opening directions that probe 2 another sides form, measuring limit 13, to lean against the track of probe 2 sides for twice symmetrical;
The open condition in D, the gap 22 that forms by 13 twice top probe 2 side, analysis to measure limit, the relation of judgement monocline probe beam axis offset angle and α,
Measure limit 13 and fit together with probe 2 sidewalls when one, another forms gaps 22 with probe 2 sidewalls, and 2 the offset angle of now popping one's head in equals the angle of angle α;
Measure limits 13 and all form gap 22 with probe 2 sidewalls when two, gap 22 opening directions are identical, and 2 the offset angle of now popping one's head in is less than the angle of angle α;
Measure limits 13 and all form gap 22 with probe 2 sidewalls when two, gap 22 opening directions are contrary, and 2 the offset angle of now popping one's head in is greater than the angle of angle α.
The method is simple to operate, and whether the offset angle that can differentiate fast probe 2 is greater than angle α; The tool construction that uses in testing process is simple, low cost can be used on a large scale and promote.
When cubing only has one to measure limit 13, in measuring process, twice use is measured limit 13 by the process intermediate demand upset cubing 1 of probe 2 sides; When dipping 12 is isosceles trapezoid, isosceles are, while measuring limit 13, not need this process, and concretely: dipping 12 is isosceles trapezoids, the waist of isosceles trapezoid is for measuring limit 13, and the part that dipping 12 is connected with centering plate 11 is trapezoidal bottom; During detection method C step, use a side side of the top probe 2 in measurement limit 13 of dipping 12, measure after gap 22 opening directions of measuring limit 13 and probe 2 sides formation; Lift the another side that dipping 12 moves to probe 2 opposite sides and uses another top probe 2 in measurement limit 13, obtain gap 22 opening directions of measuring limit 13 and probe 2 another sides formation.Finally by preceding method, judge the relation of monocline probe beam axis offset angle and α.
The method is easier, can effectively improve detection efficiency.
