Description

,(54) УСТРОЙСТВО ДЛЯ ИСПЫТАНИЯ КОЛЕЦ НА РАЗРЫВ К ИСПЫТАТЕЛЬНОЙ МАШИНЕ, (54) DEVICE FOR TESTING RINGS FOR RIP TO THE TESTING MACHINE

. t , Изобретение относитс  к испытател ной технике и может быть использовано при  спытанкК колец ма разрыв. (Известно устройство, дл  испытани  колец на разрыв к испытательной маитне , содержащее две опоры, предназначенные дл  закреплени  в захватах испытательной машины, и оправку из двух установленных на соответствующих опорах частей, имеющих цилиндрические верхности дл  установки испытуемого кол , ца и плоские поверхности, взаимодейсч вукшше между собой и расположеннь1е параллельно оси оправки l . Недостатком этого устройства  вл етс  его низка  точность , что св зано с большой податливостью частей оправки из-за их малой жесткости при испытани колец высокой кесткости. Цель изобретени  - повышение точноо ти кспь1тани . Дл  достижени  указанной пели плоские поверхности частей оправки расположёны под углом dl к ее оси, опредб;л е мым из соотношени  oL(0,9-l,l), где D - диаметр оправки; W - высота оправки. На чертеже приведена схема предл гаемого устройства. Устройство содержит две 1 и 2, щ едназначенные дл  закреплени  В захватах 3 и 4 испытательной машины, и оправку диаметром D из двух частей 5 и 6, имеюшюс цилиндрические поверхности дл  установки испытуемого взд&ли , например, кольца 7 и плоские поверхности 8, взаимодействующие между собой и расположенное под углом dl к оси 9 оправки. Угол d определ етс  из соотношени  cL(O,9-l,l)circ.tqf D/H , где Н - высота оправки. Устройство работает следующим о&« . Изделие в виде кольпа 7 диаметром D и высотой Н надевают на обе части 5 и 6 оправки. При этом поверхности 8. t The invention relates to a test technique and can be used when testing a ring break. (A device is known for testing rings for rupture to a test maitne containing two supports to be fixed in the grippers of a testing machine and a mandrel of two parts mounted on respective supports having cylindrical surfaces for mounting the test ring, and flat surfaces that interact between each other and parallel to the axis of the mandrel l. The disadvantage of this device is its low accuracy, which is due to the great flexibility of the parts of the mandrel because of their low rigidity when using Tests of high-quality rings. The purpose of the invention is to improve the accuracy of the fit. To achieve this, the flat surfaces of the mandrel parts were slanted at an angle dl to its axis, defined by the ratio oL (0.9-l, l), where D is the diameter of the mandrel; W is the height of the mandrel. The drawing shows a diagram of the proposed device. The device contains two 1 and 2, u intended to be fixed in grips 3 and 4 of the testing machine, and a mandrel with diameter D of two parts 5 and 6, which have cylindrical surfaces for the installation of the test rez &, for example, ring 7 and flat surfaces 8, interacting with each other and located at an angle dl to the axis 9 of the mandrel. The angle d is determined from the ratio cL (O, 9-l, l) circ.tqf D / H, where H is the height of the mandrel. The device works as follows about & ". The product in the form of a colp 7 with a diameter D and a height H is put on both parts 5 and 6 of the mandrel. With this surface 8
