Description
Изобретение относитс к испытательной технике. Известна установка дл испытани образцов на двухосное раст жение,- содержаща корпус, захваты и с; занные с ними две пары т г, привод и устройство дл передачи нагрузки от привода на т ги. Устройство выполнено в виде двух траверс, жестко закрепленных на одной из пар т г, в которых вы полнены прорези, двух винтовых пар, имеющих левую и правую, резьбу кажда -винты которых вход т в прорези т г перпендикул рно к их оси, двух пар р чагов, размещенных по обе стороны т и шарнирно св занных одними концами с траверсами, а другими - с гайками винтовых пар, и двух П-образных штанг, жестко св занных в средней части с другой парой т г и имеющих ролики на , взаимодействующие с рычагами ij , Данна установка вл етс наиболее .близкой к изобретению по техни .ческой сущности и достигаемому резул тату . Цель изобретени - расширение диа пазона прикладываемых нагрузок. Дл этого в рЕлчагах выполнены продольные пазы, в которых установлены ролики. На чертеже изображена данна установка . Она содержит корпус 1, захваты 2 дл креплени испытуемого плоского образца 3, св занные с ними две пары. т г 4 и 5, привод (на чертеже не показан ) и устройство дл передачи нагрузки от привода на т ги. Это устройство выполнено в виде двух траверс 6, жестко закрепленных на паре т г 5, двух винтовых пар, имеющих левую и правую резьбу, винты 7 которых вход т в прорези Т г 5 перпендикул рно к их оси и ввинчены в гайки 8, двух пар рычагов 9 с продольными пазами 10, ыарнирно св занных юдними концами с траверсами 6, а другими - с гайками 8 винтовых пар, и двух П-образных штанг 11, жестко св занных в средней части с парой т г 4 и имеющих на концах ролики 12, установленные в пазах 10 рычагов 9. Установка работает следующим образом . Нагрузка (раст гивающа , сжимающа или циклическа ) от привода передаетс на т ги 5 непосредственноThis invention relates to a testing technique. A device for testing biaxial stretch samples is known, comprising a body, grippers and c; Two pairs of couples connected with them, a drive and a device for transferring the load from the drive to the cables. The device is made in the form of two cross-beams, rigidly fixed on one of the pairs of grams in which the cuts are made, two screw pairs having left and right, the thread of which each screws are perpendicular to their axes, two pairs R chagov, located on both sides of t and pivotally connected by one ends with cross-beams, and the other with nuts of screw pairs, and two U-shaped rods rigidly connected in the middle part to another pair of tons and having rollers, which interact with levers ij, this setting is the closest to the image eniyu for Technical .cheskoy essence and achieved the results tattoo. The purpose of the invention is to expand the range of applied loads. For this, longitudinal grooves in which rollers are mounted are made in the trunks. The drawing shows this installation. It comprises a housing 1, grips 2 for fastening the test flat sample 3, and two pairs associated with them. grams 4 and 5, a drive (not shown) and a device for transferring the load from the drive to the rods. This device is made in the form of two cross-arms 6, rigidly mounted on a pair of m 5 g, two screw pairs with left and right threads, screws 7 of which fit into the slots T g 5 perpendicular to their axis and screwed into nuts 8, two pairs levers 9 with longitudinal grooves 10, harnessedly connected at their ends with cross-pieces 6, and the other with nuts 8 screw pairs, and two U-shaped rods 11 rigidly connected in the middle part with a pair of tg 4 and having rollers 12 at the ends installed in the slots 10 levers 9. The installation works as follows. The load (tensile, compressive or cyclic) from the drive is transmitted to rod 5 directly
