Description
(5) УСТРОЙСТВО ДЛЯ ДЕФЕКТОСКОПИИ ЦИЛИНДРИЧЕСКИХ ИЗДЕЛИЙ(5) DEVICE FOR DEFECTOSCOPY OF CYLINDRICAL PRODUCTS
.1 . ..one . .
Изобретение относитс к неразрушающему контролю качества материалов и изделий и может быть использовано при дефектоскопии изделий, имеющих форму тел вращени .The invention relates to non-destructive quality control of materials and products and can be used in the inspection of products having the form of bodies of revolution.
По основному авт. св. № известно устройство дл дефектоскопии цилиндрических изделий, выполненное в виде накладного вихретокового датчика , блока обнаружени дефекта, блоков кольцевой и линейной разверток, двух электронно-лучевых трубок, служащих индикаторами и синхронного электродвигател , служащего дл вращени датчика. Блок линейной развертки синхронизируетс импульсом, возникающим при вхождении конца издели в зону контрол . Длительность развертки выбираетс равной или большей времени прохождени издели через датчик. 1 ТAccording to the main author. St. No. a device is known for flaw detection of cylindrical articles, made in the form of an overlay eddy current sensor, defect detection unit, ring and linear sweep units, two cathode ray tubes serving as indicators, and a synchronous motor serving to rotate the sensor. The linear sweep unit is synchronized by a pulse that occurs when the end of the product enters the control zone. The sweep duration is selected to be equal to or greater than the time it takes for the product to pass through the sensor. 1 T
Недостатком известного устройства вл етс низка точность определени положени дефекта по длине контролируемого издели , обусловленна тем, что при изменении скорости поступательного движени издели через датчик возникает несоответствие между истинным положением дефекта на изделии и . положением импульсов засветки на экране электронно-лучевой трубки.A disadvantage of the known device is the low accuracy of determining the position of the defect along the length of the product being monitored, due to the fact that when the translational speed of the product through the sensor changes, there is a discrepancy between the true position of the defect on the product and. the position of the pulses of illumination on the screen of the cathode ray tube.
Цель изобретени - повышение томности контрол .The purpose of the invention is to increase the languor of the control.
Поставленна цель достигаетс тем, The goal is achieved by
10 что в устройство введена схема измерени скорости издели , выход которой подключен ко входу линейной развертки,10 that a device is introduced into the device for measuring the velocity of a product, the output of which is connected to the input of a linear sweep,
На чертеже изображена функциональна схема устройства дл дефектоско15 пии цилиндрических изделий.The drawing shows a functional diagram of the device for flaw detection of cylindrical articles.
Устройство содержит накладной вихретоковый преобразователь 1, блок 2 обнаружени дефекта, первую электрон20 но-лучевую трубку (ЭЛТ) 3 с кольцевой разверткой в виде фазовращател k и вторую трубку (ЭЛТ) 5 с блоком 6 линейной развертки, схему 7 измерени The device contains an invoice eddy current transducer 1, a defect detection unit 2, a first electron tube 20 (CRT) 3 with an annular scan in the form of a phase shifter k, and a second tube (CRT) 5 with a linear scan unit 6, measuring circuit 7
