Description

Изобретение относитс  к области неразрушающих испытаний материалов, в частности к акустическим методал контрол .This invention relates to the field of non-destructive testing of materials, in particular, to an acoustic control method.

Известны испытательные образцы дл  ультразвукового контрол  цилиндрических .изделий , состо щие из двух концентрично установленных одна в другой цилиндрических втулок , соединенных пайкой, внутренн   из которых Имеет искусственные дефекты с заданными геометрическими размерами в виде па наружной поверхности, заполненных материалом, непрозрач-.чым дл  ультразвука .Test samples are known for ultrasonic testing of cylindrical products consisting of two concentric cylindrical sleeves installed one inside the other, connected by soldering, internally of which Has artificial defects with specified geometrical dimensions in the form of an external surface, filled with an opaque material for ultrasound .

Недостатко.м пзвестных методов  вл етс  трудоемкость изготовлепи  составпых испытательных образцов с искусственными дефектами , расположенны.ми на разной глубине.A disadvantage of the known methods is the complexity of manufacturing test samples with artificial defects located at different depths.

Цель изобретени  - снижение трудоемкости изготовлени  испытательных образцов. Дл  достижени  этого в предлагае.мом образце втулки выполнены с равным эксцентриситетам .The purpose of the invention is to reduce the labor intensity of manufacturing test specimens. To achieve this in the proposed sample, the sleeves are made with equal eccentricities.

На чертеже изображен предлагаемый испытательный образец, .поперечный разрез.The drawing shows the proposed test sample. Cross-section.

Он содержит наружную втулку / и внутреннюю .втулку 2, которые изготовлены с равными эксцентриситетами е наружных и внутренних цилиндрических поверхностей, и соединены пайкой 3. На наружной поверхности внутренней втулки до пайки вынолнены вьтем1ки с заданными раз.мерами. Полости выемок заполн ютс  смесью порошка, выгорающего в процессе пайки, и порошка 4, непрозрачного дл  ультразвука и остающегос  вIt contains an outer sleeve / and an inner sleeve 2, which are made with equal eccentricities e of the outer and inner cylindrical surfaces, and are connected by soldering 3. On the outer surface of the inner sleeve before soldering are carried out with a given dimension. The cavities of the grooves are filled with a mixture of a powder that burns out during the soldering process, and a powder 4, opaque to ultrasound and remaining in

полости отверстий.cavity holes.

Втулки собраны так, что наружна  цилиндрическа  поверхность наружной втулки / концентрнч а внутренней втулке 2. При этом поверхность сопр жени  втулок располагаетс  в разных точках поперечного сечени  на разных рассто ни х от цилиндрической поверхности испытательного образца. В результате этого выем .ки, представл ющие собой искусственные дефекты, расположенные на поверхности сопр жени  втулок, залегают на разной глубине в толще стевки. Така  конструкци  испытательного образца позвол ет получать дефекты с заданны.ми геометрическими размерами за один прием пайки.The bushings are assembled in such a way that the outer cylindrical surface of the outer sleeve / concentric inner sleeve 2. In this case, the interface of the sleeves is located at different points in the cross section at different distances from the cylindrical surface of the test specimen. As a result, pockets, which are artificial defects located on the mating surface of the sleeves, occur at different depths in the thickness of the stevka. Such a design of the test specimen makes it possible to obtain defects with predetermined geometrical dimensions in one soldering step.
