Description
() СПОСОБ КОНТРОЛЯ КАЧЕСТВА ПОВЕРХНОСТИ ИЗДЕЛИЙ В ФОРМЕ ТЕЛ ВРАЩЕНИЯ() METHOD OF QUALITY CONTROL OF PRODUCT SURFACE IN THE FORM OF ROTATION BODIES
1one
Изобретение относитс к дефектоскопии и может быть использовано дл разбраковки больших партий изделий в форме тел вра1чени по состо нию их поверхности.The invention relates to defectoscopy and can be used for sorting large batches of products in the form of physical bodies according to the state of their surface.
По основному ант.св. М° 911127 известен способ контрол качества поверхности изделий в форме тел вращени , заключающийс в том, что контролируемое изделие скатывают по на- ю правл ющей поверхности в виде желоба, регистрируют возникающиепри этом в желобе упругие волны, а степень дефектности издели определ ют по характеристикам этих волн 13- tsAccording to the main ant.sv. The method of controlling the quality of the surface of products in the form of bodies of rotation is known as M ° 911127, which means that the product under test rolls along the guide surface as a groove, elastic waves occurring in the groove are recorded, and the degree of defectiveness of the product is determined by the characteristics of these waves 13- ts
Недостатком данного способа вл етс невозможность отбраковки изделий с дефектами в виде отслоени материала по всей длине кромок поверхности .20The disadvantage of this method is the impossibility of rejection of products with defects in the form of peeling of the material along the entire length of the edges of the surface. 20
Целью изобретени вл етс расширение области применени путем обеспечени возможности контрол дефектов типа кольцевых сколов кромок издели .The aim of the invention is to expand the scope of application by allowing the control of defects such as ring chipped edges of the product.
Эта цель достигаетс тем, что в качестве характеристики упругих волн используют длительность шумового сигнала при скатывании издели .This goal is achieved by using the duration of the noise signal as the product rolls as a characteristic of elastic waves.
На фиг. 1 и 2 представлены типа дефектных цилиндрических изделий, поддаЮ1циес контролю известным способом; на фиг. 2 - то же, не поддающиес такому контролю; на фиг. 3 схема устройства , реализующего предлагаемый способ.FIG. 1 and 2 are of the type of defective cylindrical articles, which are controlled by a known method; in fig. 2 - the same, not amenable to such control; in fig. 3 diagram of the device that implements the proposed method.
- На схеме показано контролируемое изделие 1, которое скатываетс по наклонному елобу 2, к последнему прикреплен пьезопреобразователь 3. электрический сигнал с которого поступает на вход электронного устройства k измерени длительности шумового сигнала , и с его выхода - на устройство 5 сравнени .- The diagram shows a monitored product 1, which rolls along an inclined tree 2, a piezotransducer 3 is attached to the latter. An electrical signal from which is fed to the input of the electronic device k measuring the duration of the noise signal, and from its output - to the device 5.
Способ заключаетс в следующем. 39 Контролируемое изделие 1 в форме тела вращени , например в форме цилиндра , скатывают по наклонному желобу 2, Электрическт сигнал пьезопреобразоватеп 3, регистрирующего шумовой сигнал при скатывании, подае с на устройство k, где измер етс интервал времени, в течение которого поступает сигнал с пывзопреобразовател 3. Таким образом определ ют дли тельность шумового сигнала, обусловленного взаимодействием кромок издели с поверхностью келоба. Измеренный интервал времени сравнивают с за ранее заданным браковочным уровнем в устройстве 5-сравнени . При превышении браковочного уровн с устрой-, ства S сравнени на исполнительное устройство поступает управл ющий сиг нал о браковке издели . 8 Предложенное устройство позвол ет расширить область применени контрол поверхности изделий в форме тел вращени . формула изобретени Способ контрол качества поверхности , изделий в форме тел вращени по авт.св. 11° 911127, отличающийс тем, что, с целью расширени области применени путем обеспечени возможности контрол дефектов типа кольцевых сколов Кромок издели , в качестве характеристики упругих волн используют длительность шумового сигнала при скатывании издели . Источники информации, прин тые во внимание при экспертизе 1. Авторское свидетельство СССР № 911127, кл. R,01 N .Э/Q, 1978 (прототип).The method is as follows. 39 Controlled article 1 in the form of a body of rotation, for example in the form of a cylinder, rolls along an inclined chute 2, Electrically, a piezotransform signal 3, recording a noise signal when rolling, is fed to device k, where the time interval during which the signal from the converter is measured 3. In this way, the duration of the noise signal due to the interaction of the edges of the product with the surface of the kelob is determined. The measured time interval is compared with the previously specified rejection level in the 5-device comparison. When the rejection level from the device S is exceeded, a control signal on the product rejection is sent to the actuating device. 8 The proposed device allows to expand the field of application of the control of the surface of products in the form of bodies of rotation. invention of the Method of quality control of the surface, products in the form of bodies of rotation auth.St. 11 ° 911127, characterized in that, in order to broaden the scope of application by allowing the control of defects such as ring-shaped chips of the Edge of the product, the duration of the noise signal when the product rolls is used as a characteristic of elastic waves. Sources of information taken into account during the examination 1. USSR Author's Certificate No. 911127, cl. R, 01 N .E / Q, 1978 (prototype).
