Abstract
The utility model relates to an ultrasonic flaw detection reference block of a composite structure. The ultrasonic flaw detection reference block comprises a casting and an aluminum substrate. The casting is cast on the aluminum substrate to form the composite structure. Eight measurement holes with the diameters being arithmetic progression are formed in the direction of a composite layer of the composite structure. The minimum diameter of the measurement holes is 0.5 mm, the maximum diameter of the measurement holes is 4 mm, and the tolerance is 0.5 mm. According to the ultrasonic flaw detection reference block, the detection capacity of an ultrasonic detection system of the composite structure can be improved, and the reference block can also be used for adjusting the sensitivity before detection, so that the detection result is more accurate, specific and convincing.
Description
Technical field:
The utility model relates to a kind of defect-detecting equipment, specifically a kind of compound structure supersonic wave inspection reference block.
Background technology:
Composite structure is to have two or more properties of materials simultaneously, and its outstanding behaviours goes out the characteristic of bi-material, and both are matrix altogether, so more can fully demonstrate the advantage of two kinds of materials.Composite structure can be improved mechanical property, physical property and the chemical property of single conventional material to a great extent, and can solve and in engineering structure, adopt the more insurmountable critical problems of conventional single construction material (or compound substance).Owing to affecting, the factor of composite structure integrality is a lot of, and the fine difference of many technological parameters all can cause it to produce defect, makes product quality present obvious discreteness, and these defects have a strong impact on mechanical property and the integrality of member.Conventionally select ultrasonic flaw detection to detect to the detection means of above-mentioned defect.Reference block can be used for adjusting sensitivity, the measurement range of instrument, also can be used for the size of comparison defect.But reference block is made of the material identical or close with workpiece acoustic performance to be checked.
At present, the waveform that conventional reference block obtains and the waveform of measured workpiece differ greatly, and can not complete Detection task.
Utility model content:
The purpose of this utility model is exactly for above defect, and a kind of ultrasound examination reference block of composite structure is provided.
For achieving the above object, the utility model proposes following technical scheme:
The reference block of a kind of compound structure supersonic wave inspection, it is characterized in that: comprise foundry goods, aluminum substrate, described cast casting forms composite structure on aluminum substrate, composite bed direction along described composite structure is processed with the measured hole that eight diameters are arithmetic progression, the minimum diameter of described measured hole is 0.5mm, and maximum gauge is 4mm, and tolerance is 0.5mm, hole depth is more than or equal to 10mm, and the distance in adjacent two holes of described measured hole is more than or equal to 8mm.
Described measured hole center line overlaps with composite bed.
Described aluminum substrate thickness is greater than 40mm.
The beneficial effects of the utility model are: the compound structure supersonic wave inspection reference block that the utility model discloses has met the requirement of the quantitative measurment of the UT (Ultrasonic Testing) detection of composite structure, draw out distance-squiggle, regulate the sensitivity of detection system, make testing result more truly, more accurate, and this test block is simple in structure, easy to process.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing of the present utility model, to the technical scheme of the utility model embodiment remove, complete description.
As shown in Figure 1: a kind of compound structure supersonic wave inspection reference block that the utility model discloses, comprise foundry goods 1, aluminum substrate 2, described cast casting forms composite structure on aluminum substrate 2, be processed with along the composite bed direction of described composite structure the measured hole 3 that eight diameters are arithmetic progression, the minimum diameter of described measured hole 3 is 0.5mm, and maximum gauge is 4mm, and tolerance is 0.5mm, hole depth is more than or equal to 10mm, and the distance in adjacent two holes of described measured hole 3 is more than or equal to 8mm.
Further, described measured hole 3 center lines overlap with composite bed.
Further, described aluminum substrate 2 thickness are greater than 40mm.
Compound structure supersonic wave inspection of the present utility model reference block is identical with conventional reference block using method in using method.By different pore size is carried out to carrying out flaw detection, draw distance-amplitude curve, determine flaw detection sensitivity and evaluate defect size.Its result in the time detecting engine piston with ring carrier groove structure is accurate, is well used in practice.
Technology contents of the present utility model and technical characterictic have disclosed as above; but those of ordinary skill in the art still may be based on teaching of the present utility model and announcements and are done all replacement and modifications that does not deviate from the utility model spirit; therefore; the utility model protection domain should be not limited to the content that embodiment discloses; and should comprise various do not deviate from replacement of the present utility model and modifications, and contained by present patent application claim.
