Abstract
The utility model relates to an adhesive sound velocity calibration block, and belongs to the technical field of ultrasonic flaw detection. The adhesive sound velocity calibration block comprises a calibration block body (1), wherein the calibration block body (1) is made of adhesives, stair-shaped steps (2) are arranged on the upper surface of the calibration block body (1), the number of the steps (2) is four, and the heights of the four steps (2) are 5mm, 10mm, 15mm and 20mm in sequence respectively. The adhesive sound velocity calibration block is reasonable in structure and exquisite in design, and can be applied to ultrasonic detection of blades of wind driven generators.
Description
Technical field
The utility model relates to a kind of ultrasonic flaw detection briquette, specifically relates to a kind of adhesive glue sound velocity calibration test block, belongs to UT (Ultrasonic Testing) technical field.
Background technology
UT (Ultrasonic Testing) is to utilize ultrasonic energy to penetrate the depths of metal material, and while entering another cross section by a cross section, the feature that occurs to reflect in interface edge checks a kind of method of part defect, when ultrasonic beam passes to metal inside from piece surface by probe, while running into defect and part bottom surface, just there is respectively reflection wave, on video screen, form pulse waveform, according to these pulse waveforms, judge defective locations and size.But UT (Ultrasonic Testing) technology is applied in conventionally in the Non-Destructive Testing of metal (especially steel and products thereof) at present, also not for glass fiber reinforced plastics composite material, particularly be applied in the ultrasonic detection method on blade of wind-driven generator (fiberglass parts), also there is no corresponding calibration block.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of adhesive glue sound velocity calibration test block is provided, and it can be applied to the ultrasound examination of blade of wind-driven generator.
The purpose of this utility model is achieved in that a kind of adhesive glue sound velocity calibration test block, it comprises test block body, described test block body is made by adhesive glue, described test block body upper surface is provided with stepped step, described step has quadravalence, and the height of described quadravalence step is followed successively by 5mm, 10mm, 15mm and 20mm.
Described test block body is rectangular parallelepiped, and described test block body is of a size of 160mm * 80mm * 20mm.
Compared with prior art, the utlity model has following beneficial effect:
A kind of adhesive glue sound velocity calibration of the utility model test block, it is rational in infrastructure, designs ingeniously, can be applied to the calibration block in power-driven generator leaf ultrasound examination.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of adhesive glue sound velocity calibration of the utility model test block.
Fig. 2 is the left view of Fig. 1.
Wherein:
Step 2.
Embodiment
Referring to Fig. 1, Fig. 2, a kind of adhesive glue sound velocity calibration of the utility model test block, it comprises test block body 1, described test block body 1 is made by adhesive glue, described test block body 1 is rectangular parallelepiped, and described test block body 1 is of a size of 160mm * 80mm * 20mm, and described test block body 1 upper surface is provided with stepped step 2, described step 2 has quadravalence, and the height of described quadravalence step 2 is followed successively by 5mm, 10mm, 15mm and 20mm.
The utility model is the speed in blade of wind-driven generator adhesive glue mainly for detection of calibration ultrasound wave.
