Description

A detection device for the pressure change performance of an O-shaped rubber sealing ring

【Technical field】

The utility model relates to the technical field of sealing rings, in particular to a detection device for the pressure change performance of an O-shaped rubber sealing ring.

【Background technique】

The constant deformation compression permanent deformation of the O-shaped rubber sealing ring is one of the important indicators of the performance of the sealing ring, and this constant deformation compression permanent deformation is determined by testing the size of the axial section diameter of the O-shaped rubber sealing ring before and after compression According to the calculated data, the manufacturer adjusts the formula and process to meet the use requirements according to the measured data. Therefore, whether the measured constant deformation compression permanent deformation is accurate or not plays a decisive role in the material performance of the O-shaped rubber sealing ring. .

In the daily detection of the size of the O-shaped rubber sealing ring before and after pressure change, two movable clamps are stuck in the sliding groove of a base, the O-shaped rubber sealing ring is fixed in the middle, and the radial direction of the O-shaped rubber sealing ring is adjusted. The height and the height of the two clamping blocks are in the same plane, and then move the radial section diameter edge of the sealing ring to the detection line position of the detection instrument imager for detection. When adjusting the height, it is often necessary to hold the sealing ring with one hand to adjust the height, and the other hand to move the two clamps to fix it. If the fixing is not good, the O-shaped rubber sealing ring will often fall off, especially the small O-shaped rubber sealing ring. In this way, the detection time is longer; at the same time, because the height is adjusted by hand, there is a certain deviation. If the height of the sealing ring is higher than the height of the chuck, the detected size is too large, and if it is lower, the detected size is too small; In addition, the two clamping blocks are movable, and sometimes there will be a certain deflection, so that the radial edge of the sealing ring deviates from the detection line of the detection instrument imager, and there is a certain deviation in the size of the detected O-shaped rubber sealing ring. The resulting data for constant deformation compression set are less accurate.
