изобретение относитс  к измерительной технике, а именно, к тензометрам дл  измерени  деформации твердых тел.The invention relates to a measurement technique, namely, strain gauges for measuring the deformation of solids.

По основному авт. св. 560124 известен тензометр,- содержащий корпус , расположенные в одной плоскости две пластинчатые опоры с пишущими кернами, сменный носител записи, упругую скобу с выступом, св зывающую планки. В корпусе выполнена выемка, в которую помещен выступ III .According to the main author. St. 5,60124 a tensometer is known, comprising a body, in the same plane, two plate supports with writing cores, a removable recording medium, an elastic bracket with a protrusion connecting the strips. In the case there is a notch in which the projection III is placed.

Недостаток тензометра - низка  точность измерений, св занна  с тем,что пишупдае керны смещаютс  за счет смещени  кромок трещины в исследуемом образце и за счет прогиба образца , что создает неопределенность при определении скорости деформировани .The disadvantage of the strain gauge is low measurement accuracy due to the fact that the cores are shifted due to the displacement of the edges of the cracks in the sample under study and due to the deflection of the sample, which creates uncertainty in determining the strain rate.

Цель изобретени  - повьаиение точности записи деформации.The purpose of the invention is to improve the accuracy of the recording of the deformation.

Поставленна  цель достигаетс  тем, что в тензометре планки снабжены штифтами, а в корпусе наклонно по отношению к линии, соедин кадей пишущие керны, выполнены пазы,,в которых размещены штифты.The goal is achieved by the fact that the straps are equipped with pins in the strain gauge, and in the case obliquely with respect to the line, the connecting core has writing cores, grooves are made in which the pins are placed.

Ка чертеже схематически представлен предлагаемый тензометр, общий вид.The drawing shows schematically the proposed tensometer, general view.

Тензометр содержит корпус 1, расположенные в одной плоскости две планки 2 и 3 с пишущими кернами 4 и 5 на одних из их концов (другими концами планки 2 и 3 опираютс  на образец б) и носитель записи 7, параллельный плоскости пластинчатых планок 2 и 3, установленные в корпусеThe strain gauge contains a body 1, two strips 2 and 3 located in one plane with writing cores 4 and 5 at one of their ends (the other ends of strips 2 and 3 are supported on sample b) and a record carrier 7 parallel to the plane of the plate strips 2 and 3, installed in the housing

I.Планки 2 и 3 снабжены штифтами 8 I.Plans 2 and 3 are equipped with pins 8

0 и 9, а в корпусе 1 выполнены наклонно по отнс  ению к линии, соедин ющей керны 4 и 5, пазы 10 и 11, в которых размещены штифты 8 и 9.0 and 9, and in the housing 1, the slots 10 and 11 are inclined with respect to the line connecting the cores 4 and 5, in which the pins 8 and 9 are placed.

Тензометр работает следующим обра5 зом.The strain gauge works as follows.

При деформировании (например, раст жении ), образца 6, штифты 8 и 9, перемеща сь по наклонным пазам 10 иWhen deforming (for example, stretching) sample 6, pins 8 and 9, move along inclined grooves 10 and

II,заставл ют носитель записи 7 пе0 ремещатьс  перпендикул рно линии, соедин кадей керны 4 и 5, в плоскости планок 2 и 3. При этом керны 4 и 5 оставл ют на носителе записи след, расшифровка которого позвол ет су5 дить о деформации образца и о дина1«мке ее изменени  при деформировании.II, cause the recording medium 7 to move perpendicular to the line, connecting cores 4 and 5, in the plane of the slats 2 and 3. At the same time, cores 4 and 5 leave a trace on the recording medium, deciphering which makes it possible to detect the deformation of the sample and You will have to change it when deforming.

: Предлагаемое устройство позвол ет повысить точность записи деформации /за счет введени  надежного привода0 носител  записи.: The proposed device improves the accuracy of the recording of the deformation / by introducing a reliable drive 0 of the recording medium.
