(54) УСТРОЙСТВО ДЛЯ МЕХАНИЧЕСКИХ ИСПЫТАНИЙ ПОЛИМЕРНЫХ МАТЕРИАЛОВ(54) DEVICE FOR MECHANICAL TESTS OF POLYMER MATERIALS
1one
Изобретение относитс к испытательной технике, в частности к устройствам дл механических испытаний полимерных материалов .The invention relates to a test apparatus, in particular to devices for the mechanical testing of polymeric materials.
Известно устройство дл механических испытаний полимерных материалов, содержащее станину, острозубые параллельно расположенные барабаны, установленный параллельно оси барабанов ходовой винт, на котором смонтирован с возможностью перемещени узел креплени испытываемого объекта, и привод с тормозом 1.A device for mechanical testing of polymeric materials is known, comprising a frame, sharp-toothed parallel-mounted drums, a lead screw mounted parallel to the axis of the drums, on which the mount of the test object is mounted and can be moved with a brake 1.
Недостатком известного устройства вл етс то, что оно не обеспечивает посто нства давлени образца на скалывающие поверхности.A disadvantage of the known device is that it does not ensure the constant pressure of the sample on the shearing surfaces.
Цель изобретени - повышение точности испытаний.The purpose of the invention is to improve the accuracy of the tests.
Поставленна цель достигаетс тем, что устройство снабжено нагружающим устройством , выполненным в виде поворотного кронщтейна с набором грузов, закрепленного на ходовом винте.The goal is achieved by the fact that the device is equipped with a loading device, made in the form of a swivel arm with a set of weights, mounted on the lead screw.
На фиг. 1 изображено предлагаемое устройство, вид сверху; на фиг. 2 - то же, вид сбоку.FIG. 1 shows the proposed device, top view; in fig. 2 - the same, side view.
Устройство содержит станину 1, два параллельных острозубых барабана 2, ходовой винт 3, узел 4 креплени образца, привод 5, поворотный кронщтейн с набором грузов 7.The device comprises a frame 1, two parallel sharp-toothed drums 2, a lead screw 3, a sample fastening assembly 4, a drive 5, a swivel arm with a set of weights 7.
Устройство работает следующим образом.The device works as follows.
Узел 4 креплени навинчиваетс на ходовой винт 3, который жестко соединен с кронштейном 6. Набором грузов 7 создаетс заданна нагрузка. Включают привод 5, вращение от которого передаетс барабану 2 и от него узлу 4 креплени , который, враща сь, перемещаетс вдоль ходового винта 3. Под действием осевой нагрузки и боковых сил образец изнащиваетс об острозубые барабаны 2.The fastener assembly 4 is screwed onto the lead screw 3, which is rigidly connected to the bracket 6. A set of loads is created by the set of weights 7. The actuator 5 is turned on, the rotation from which is transmitted to the drum 2 and from it to the attachment unit 4, which, rotating, moves along the lead screw 3. Under the action of axial load and lateral forces, the specimen wears on sharp-toothed drums 2.
Использование предлагаемого устройства позвол ет повысить стабильность контактного давлени , исключает перекос ходового The use of the proposed device allows to increase the stability of the contact pressure, eliminates the imbalance of the
15 винта, в результате чего повышаетс точность испытаний.15 screws, resulting in improved test accuracy.
