Abstract
Изобретение относитс к испытательному оборудованию, в частности к захватным устройствам. С целью повышени достоверности за счет снижени концентрации напр жений в образце у вершины губок, участок каждой губки со стороны ее вершины выполнен в виде лепестков, равномерно расположенных по окружности с зазорами между ними и имеет конусность меньше конусности участка, расположенного со стороны основани губки, на рабочей поверхности которого выполнена кольцева проточка, разжимной элемент выполнен сферическим и предназначен дл взаимодействи с участком губки большей конусности, а захват снабжен ст жным элементом, размещенным в проточке. Захват снабжен упором в виде стакана дл размещени образца, дно которого взаимодействует с основанием губок и предназначено дл взаимодействи с торцевой поверхностью образца. 1 з.п. ф-лы, 1 ил.The invention relates to test equipment, in particular to gripping devices. In order to increase reliability by reducing the concentration of stresses in the sample near the top of the sponges, the area of each sponge on the side of its top is made in the form of petals evenly spaced around the circumference with gaps between them and has a taper smaller than the conicity of the section located on the side of the sponge base the working surface of which is made an annular groove, the expanding element is made spherical and is designed to interact with the section of the sponge of greater taper, and the grip is provided with a tensioning element placed m in the groove. The gripper is provided with an emphasis in the form of a glass for placing a sample, the bottom of which interacts with the base of the jaws and is intended to interact with the end surface of the sample. 1 hp f-ly, 1 ill.
Description
Изобретение относитс к испытательному оборудованию, в частности к захватным устройствам.The invention relates to test equipment, in particular to gripping devices.
Цель изобретени - повышение достоверности результатов испытаний за счет снижени концентрации напр жений в образце у вершины губок путем выполнени этого участка губок в виде расположенных по окружности лепестков .The purpose of the invention is to increase the reliability of the test results by reducing the concentration of stresses in the sample at the tip of the jaws by making this area of jaws in the form of petals located around the circumference.
На чертеже изображен захват, общий вид.The drawing shows the capture, general view.
Захват дл трубчатых образцов при испытании на прочность содержит разжимные клиновые губки 1 и 2 с заостренными вершинами 3, участки 4 и 5 губок 1 и 2 со стороны вершин 3 выполнены в виде лепестков, располо- женных равномерно по окружности с зазором 6, при этом конусность участков 4 и 5 меньше конусности участков (не обозначены), расположенных со стороны оснований губок 1 и 2. На цилиндрической рабочей поверхности (не обозначена) губок 1 и 2, предназначенной дл взаимодействи с внутренней поверхностью образца 7, в зоне участков с большей конусностью выполнена проточка 8. Захват также содержит сферический разжимной элемент 9, св занный посредством штокаThe grip for tubular specimens, when tested for strength, contains expanding wedge sponges 1 and 2 with pointed tops 3, portions 4 and 5 of sponges 1 and 2 on the side of tops 3 are made in the form of petals evenly spaced around the circumference with a gap of 6, while the taper sections 4 and 5 are smaller than the tapering sections (not marked) located on the side of the bases of the jaws 1 and 2. On the cylindrical working surface (not marked) of the jaws 1 and 2, designed to interact with the inner surface of the sample 7, in the area of the sections with the larger taper Strongly a groove 8. Capture also contains spherical expansible member 9 is coupled by a rod
