Description

Известны устройства дл  автоматического ультразвукового контрол  листовых материалов иммерсионным методом, в которых исследуемый лист вертикально установлен в заполненном жидкостью сосуде вместе с жестко скрепленными между собой излучателем и приемником ультразвуковых колебаний, приводимых в горизонтальное возвратно-поступательное движение у поверхносги листа одновременно с вертикальным перемещением последнего и с применением в качестве источника электрических импульсных колебаний тиратронных генераторов.Devices for automatic ultrasonic testing of sheet materials by the immersion method are known in which the test sheet is vertically installed in a vessel filled with liquid, together with an emitter and receiver of ultrasonic vibrations rigidly fastened together, driven in a horizontal reciprocating motion at the surface of the sheet simultaneously with the vertical movement of the latter and with use as a source of electric pulse oscillations of thyratron generators.

Предлагаемое устройство аналогичного назначени  отличаетс  or известных тем, что дл  повышени  точности фиксации дефектов в цепи приемника применена триггерна  схема с двум  стабильными положени ми . Один из входов триггерной схемы непосредственна соединен с генератором импульсов, а второй вход через дополнительный тиратрон подключен k выходу усилител  приемника колебаний. Дополнительный тиратрон служит амплитудным селектором и осуществл ет поочередную переброску триггера из одного положени  в другое под действием обоих сигналов таким образом, чтобы включение сигнального приспособлени  происходило в случае ослаблени  сигнала на выходе приемника в результате наличи  дефекта в провер емом листе.The proposed device of similar purpose is distinguished or known in that a trigger system with two stable positions is used to improve the accuracy of fixing defects in the receiver circuit. One of the trigger circuit inputs is directly connected to the pulse generator, and the second input is connected via an additional thyratron to the k output of the oscillation receiver amplifier. The additional thyratron serves as an amplitude selector and alternately transfers the trigger from one position to another under the influence of both signals so that the signal device is turned on in the event of a weakening of the signal at the receiver output as a result of a defect in the sheet being checked.

На чертеже приведена принципиальна  схема электронной части описываемого устройства.The drawing is a schematic diagram of the electronic part of the described device.

В описываемом устройстве дл  автоматического ультразвукового контрол  листовых материалов производитс  автоматическое построчное исследование всей поверхности провер емого листа с помощью системы из жестко скрепленных между собой излучателей и приемников ультразвуковых колебаний. Этой системе с помощью черв чных винтов сообщают горизонтальное возвратно-поступательное движение с обеих сторон листа по всей его щирине. Одновременно всему листу сообщаетс  вертиIn the described device for automatic ultrasonic testing of sheet materials, automatic line-by-line examination of the entire surface of the sheet under test is performed using a system of ultrasonic vibrations rigidly bonded to each other. With the help of screw screws, this system is reported to have horizontal reciprocating motion on both sides of the sheet throughout its width. At the same time, the whole sheet is informed
