Description
Изобретение относитс к неразрушающим испытани м ультразвуковым методом и может быть использовано дл контрол изделий.The invention relates to non-destructive ultrasonic testing and can be used to control products.
Известен..способ ультразвукового контрол изделий, зак.пючающийс в том/ что в изделие излучают колебани , принимают прошедшие через изде .лие колебани и по уменьшению амплитуды суд т о качестве издели 1.The method of ultrasonic testing of products is known, which concludes in the fact that oscillations emit into the product, accept oscillations passing through the product and, judging by the decrease in amplitude, judge the quality of product 1.
Известно устройство дл контрол качества изделий, содержащее генератор зондирующих импульсов, излучающий и .приемный преобразователи, усилитель, автоматический сигнализатор дефекта и блок регистрации 2.A device for quality control of products is known, comprising a probe pulse generator, emitting and receiving transducers, an amplifier, an automatic defect signaling device and a recording unit 2.
Недостатком известных способа и устройства вл етс отсутствие информации о глубине замечани дефекта .A disadvantage of the known method and device is the lack of information about the depth of observation of the defect.
Наиболее близким к предлагаемому по технической сущности и достигаемому результату вл етс способ ультразвукового теневого контрол изделий, заключающийс в том,.что устанавливают две пары преобразователей относительно издели по схеме X, перемещают преобразователь и изде-лие относительно друг друга, излучают в издели колебани , принимают прошедшие колебани и определ ют амплитуды сигналов, отраженных от дефектов в изделии, по которым суд т о качестве издели 3. The closest to the proposed technical essence and the achieved result is the method of ultrasonic shadow control of products, which consists in installing two pairs of transducers relative to the product according to the scheme X, moving the transducer and the product relative to each other, emit vibrations in the product, accept oscillations and determine the amplitudes of the signals reflected from defects in the product, judging by the quality of the product 3.
Известный способ осуществл етс устройством дл ультразвукового теневого контрол изде.лий, содержащем генерагор зондирующих импу.пьсов,два канала измерений, каждый из ко10 торых состоит из последовательно соединенных излучающего преобразовател , подключенного к выходу генератора зондирующих импульсов, приемного преобразовател и усилител 4J.The known method is carried out by a device for ultrasonic shadow control products, containing a generator of probing pulses, two measurement channels, each of which consists of a series-connected radiating transducer connected to the output of the probe pulse generator, the receiving transducer and 4J amplifier.

Недостатком известных способа и устройства вл етс отсутствий информации о глубине залегани дефекта .A disadvantage of the known method and device is the lack of information about the depth of the defect.
Цель изобретени - обеспечение The purpose of the invention is to provide
20 определени глубины залегани дефекта .20 determine the depth of the defect.
Поставленна цель достигаетс тем, что в известном способе ультразвукового теневого контрол изделий, The goal is achieved by the fact that in the known method of ultrasonic shadow control of products,
25 заключающемс в том, что устангшливают-две пары преобразователей относительно издели по схеме X, перемещают преобразователь п изделие относительно друг друга, излучают 25 which consists of installing two pairs of transducers relative to the product according to the scheme X, moving the transducer and the product relative to each other, emit
