Description

Technical Field

[0001] The utility model belongs to the technical field of sealing ring detection, in particular to a sealing ring detection device. Background Art

[0002] A sealing ring is an accessory used for sealing. It provides good sealing performance within the working pressure and a certain temperature range. As the pressure increases, the sealing ring can maintain a good sealing effect. The shapes of the sealing ring include round, square and special shapes.

[0003] The production process of sealing rings requires mold design, selection and processing of raw materials, vulcanization molding, removal of burrs and burrs, testing and packaging, etc. In the sealing ring testing step, the sealing ring needs to be tested for compression resistance. The compressive strength test is to evaluate the ability of the sealing ring to resist deformation and rupture when subjected to pressure. During the test, the pressure is gradually increased to observe the deformation and failure of the sealing ring. In the existing sealing ring detection device technology, in a fixed detection device, when testing square sealing rings of different sizes, it is necessary to replace different fixtures for testing. The steps are cumbersome and may affect the efficiency of the test.
