Description
и дополнительную каретку 4, установленные на рабочем торне CTCpXFreBoro сердечника 2, скобу 5, установленную на нерабочем торце катуики I электромагнита, упругий элемент 6 в виде пружины, служащей дл упругого креплени стержневого сердечника 2 к скобе 5, каретку 7, на которой установлена катушка 1 электромагнита. Позицией 8 на чертеже обозначен источник питани преобразовател . .and an additional carriage 4 mounted on the CTCpXFreBoro operating core 2 of the core 2, a bracket 5 mounted on the non-working end of the katuiki I electromagnet, a spring element 6 in the form of a spring serving for elastic attachment of the core core 2 to the bracket 5, the carriage 7 on which the coil 1 is mounted electromagnet. Position 8 in the drawing denotes the power source of the converter. .
Устройство работает следующим образом .The device works as follows.
При включении источника 8 питани стержневой сердечник 2 под воздействием пружины б занимает определенное положение в канале катушки 1 электромагнита. Когда под электромагнитом по вл етс контролируемое изделие,стержневой сердечник 2 прит гиваетс к его поверхности гиагнитным полем .When the power source 8 is turned on, the core core 2 under the influence of the spring b occupies a certain position in the channel of the coil 1 of the electromagnet. When a controlled product appears under the electromagnet, the core core 2 is attracted to its surface by a magnetic field.
При взаийном перемещении электромагнитно-акустического преобразовател и издели с неровной поверхностью зазор между стержневым сердечником 2 с высокочастотной , катушкой 3 и поверхностью издели всегда остаетс посто нным за счет 1 аличи дополнительной каретки 4 и подпружинивани стержневого сердечника 2.When the electromagnetic-acoustic transducer and the product with an uneven surface have a reciprocal movement, the gap between the core core 2 with the high-frequency coil 3 and the surface of the product always remains constant due to the difference in the additional carriage 4 and the spring core core 2.
Применение такого электромагмитно-акустического преобразовател позвол ет повысить чувствительность при контроле изделий с неровной поверхностью.The use of such an electromagnetic-acoustic transducer allows to increase the sensitivity when testing products with an uneven surface.
