Rubber ring mechanical performance testing device

Abstract

The invention discloses a mechanical property detector for a rubber ring. The mechanical property detector comprises an inner seat, wherein a supporting shaft is fixedly connected with the lower surface of the inner seat; an annular groove is formed in the upper surface of the inner seat; the rubber ring is mounted in the annular groove; a mounting hole is formed in the outer side wall of the annular groove; a first detecting component is mounted in the mounting hole; a housing is mounted above the inner seat; the housing is in clearance fit and coaxial with the inner seat; an annular bulge matched with the rubber ring is arranged on the surface, close to the inner seat side, of the housing; the annular bulge and the annular groove are combined to form a closed annular cavity; a pressing shaft is connected with the housing; second detecting components are arranged at the two ends of the pressing shaft. The mechanical property detector disclosed by the invention has the benefits of being used for the testing method of assessing the constraint compression performance of the rubber ring, and establishing the mechanical property of the rubber ring product.

Description

technical field [0001] The invention relates to the field of testing mechanical properties of materials, in particular to a testing device for mechanical properties of rubber rings. Background technique [0002] The rubber ring is a commonly used buffer and energy-absorbing structural part in a vibration environment. Its mechanical properties have a direct impact on the reliability and stability of the equipment in a vibration environment. Therefore, it is necessary to measure the mechanical properties of the rubber ring. Since the rubber ring is a soft and easily deformable product, its mechanical properties are difficult to accurately detect. Structure and other mechanical properties, process performance, internal defects and precision side-view instrument for checking the dynamic unbalance of rotating parts) loading can directly obtain the axial pressure of the rubber ring and the corresponding axial compression deformation, but it is difficult to obtain the compression o...
