Изобретение касаетс размерного контрол в машиностроении, в частности контрол больших диаметров.The invention relates to dimensional control in mechanical engineering, in particular, control of large diameters.
Известны способы проверки измерительных устройств с обкатным роликом с использованием образцового издели , при котором аттестуют один из параметров образцового издели , например наружный диаметр, а провер емым устройством измер ют св занный с ним параметр, например длину соответствующей окружности.Methods are known for testing measuring devices with a rolling roller using a sample product, in which one of the parameters of a model product is certified, for example, the outer diameter, and a parameter related to it, such as the length of a corresponding circle, is measured with a device under test.
Однако аттестаци диаметра крупногабаритного издели весьма затруднительна и св зана с по влением погрешности аттестации.However, attestation of the diameter of a large-sized product is very difficult and is associated with the occurrence of an attestation error.
Целью изобретени вл етс повышение точности проверки путем снижени погрешности аттестации.The aim of the invention is to improve the accuracy of verification by reducing the attestation error.
Дл этого в качестве образцового издели используют кольцо, у которого аттестуют толщину стенки, а провер емым устройством измер ют длины наружной и внутренней окружностей кольца.For this purpose, a ring is used as a model article, at which the wall thickness is certified, and the lengths of the outer and inner circles of the ring are measured by a verifiable device.
Выбрав образцовое изделие, подготавливают дл измерени его наружную и внутреннюю поверхности, после чего аттестуют толщину стенки достаточно точными средствами, что ввиду малости этой толщины может быть сделано без больших затруднений с высокойBy selecting a model product, it is prepared to measure its outer and inner surfaces, after which the wall thickness is certified using sufficiently accurate means, which, in view of the smallness of this thickness, can be done without much difficulty with high
точностью.accuracy.
Затем провер емым ycTpoiicTBOM последовательно обкатывают обе поверхности и определ ют их диаметры. Полуразность этих диаметров сравнивают с аттестованной толщинойThen, the tested ycTpoiicTBOMs successively roll around both surfaces and determine their diameters. The semi-difference of these diameters is compared with the certified thickness
стенки, что позвол ет судить о точности измерительного устройства с обкатным роликом.wall, which allows to judge the accuracy of the measuring device with a rolling roller.
