A performance testing device for a rotary positioning type o-shaped rubber sealing ring

Abstract

The invention discloses a rotary positioning type O-shaped rubber sealing ring performance detection device. The device comprises a base, pushing devices, rotary driving devices, pressing plates, a mounting plate, a hanging rod and a positioning component. According to the rotary positioning type O-shaped rubber sealing ring performance detection device of the invention, after an O-shaped rubber sealing ring is installed on an elastic opening-closing chuck at the bottom of the hanging rod, the hanging rod is preferentially rotated, so that the T-shaped rotary clamping tooth of the hanging rodrotates in the T-shaped rotary clamping groove of the mounting plate; and after the T-shaped rotary clamping tooth of the hanging rod rotates to a desired position, the external threaded post of the positioning component passes through the connection channel of the mounting plate so as to be in threaded connection with an internal threaded hole at the upper end of the T-shaped rotary clamping tooth, and at the same time, the annular ring of the lower end surface of the positioning plate is connected into the annular groove of the upper end surface of the mounting plate in an abutting manner, and therefore, locking is achieved, and the O-shaped rubber sealing ring will not change due to the rotation of the position of the O-shaped rubber sealing ring during extrusion, and the defect of unstable connection can be avoided.

Description

technical field [0001] The invention relates to a performance detection device of a rotary positioning type O-shaped rubber sealing ring. Background technique [0002] O-shaped rubber sealing rings are generally used to seal gases or liquids, but in different environments, O-shaped rubber sealing rings are often subjected to different degrees of external forces such as extrusion, stretching, friction, etc. In these environments, O-shaped rubber sealing rings Whether the internal structure and various performances of the O-shaped rubber sealing ring have changed, and how much the change needs to be sent to the detection line position of the imager for detection, but in the existing equipment, it is not convenient to make the O-shaped rubber sealing ring happen. It is necessary to detect the deformation requirements of performance, or the use function is relatively single, and the connection is not stable. Contents of the invention [0003] Aiming at the deficiencies of the...
