Изобретение относитс К измерительной технике и может быть использовано при исслеаовании механических свойств материалов.The invention relates to a measuring technique and can be used in the study of the mechanical properties of materials.
Известно устройство, ол измерени усилий к испытательной машине, соаержащее рычажно-ма тниковый сипоизмеритель , опора которого пре щазначена дл устанс ки на траверсе машины, а ото из плеч рычага преоназначено дл шарHHfMoft св зи с захватом tljA device is known that measures the forces applied to a test machine, which contains a lever-rim metering device, the support of which is intended for installation on the traverse of the machine, and that from the arms of the lever is intended for a ball Hlfmoft coupling with a grip tlj
Нецостатком этого устройства вл етс невозможность провецени на нем испытани на раст жение - сжатие без перестановки образца.A disadvantage of this device is the impossibility of carrying out a tensile test on it - compression without moving the specimen.
Наиболее близким к г|}еалагвемому по технической сущности и достигаемому результату вл етс устройство дл измерени усилий к испытательной машине, включающее в себ трубчатый упругий элемент и систему измерени его аефор- маиии ГThe device closest to r |}, which is technically and achievable, is a device for measuring forces to a testing machine, which includes a tubular elastic element and a system for measuring its strength and
Недостатком этого устройства вл етс его низка точность, так как при цикли-The disadvantage of this device is its low accuracy, since during cycling
ческих испытани х с переходом через О датчик работает то на раст жение, то на сжатие, что приводит к искажению записываемой анаграммы и большим погрешност м при малых нагрузках.This method of testing with passing through an O-sensor works either in tension or compression, which leads to a distortion of the recorded anagram and large errors at low loads.
Цель изобретени - повышение точное ти измерени путем обеспечени работы упругого элемента только на сжатие.The purpose of the invention is to increase the exact measurement by ensuring that the elastic element works only in compression.
Дл достижени этой цели устройство снабжено фланцами, размещенными на торцах упругого элемента, один из которых прешазначен дл установки его в траверсе испытательной машины, двум гайками, предназначенными дл установки на т ге испытательной машины с возможностью взаимодействи их с фланцами , и втулкой с наружной резьбой, установленной коаксиально одной из гаек с возможностью взаимодействи со вторым фланцем и предназначенной дл закреплени ее с помощью резьбы в траверсе испытательной машины.To achieve this goal, the device is equipped with flanges located on the ends of the elastic element, one of which is pre-assigned to be installed in the traverse of the testing machine, two nuts to be installed on the rod of the testing machine with the possibility of their interaction with the flanges, and a sleeve with external thread, installed coaxially one of the nuts with the ability to interact with the second flange and designed to secure it with a thread in the traverse of the testing machine.
