The utility model belongs to the technical field of
wear resistance testing devices, and particularly relates to a
wear resistance testing device suitable for a
piston sealing ring, which comprises a testing cabinet and a control panel arranged on the surface of the testing cabinet, one side of the testing cabinet is connected with a supporting bottom frame, one side of the testing cabinet is connected with a rotating shaft, and the rotating shaft is connected with a rotating shaft. According to the
piston sealing ring testing device, the limiting plate is stretched outwards, then a
piston sealing ring to be tested is connected to the clamping end of one end of the clamping block, at the moment, the first linkage plate connected with the limiting plate pulls the clamping spring to be elastically stretched, the piston sealing ring to be tested is clamped in the clamping spring, and then the piston sealing ring to be tested is clamped in the clamping spring. The piston sealing ring to be tested is rapidly clamped and stabilized, then the air cylinder is driven to enable the piston sealing ring to be close to the
abrasive paper wheel, friction testing is conducted on the piston sealing ring through rotation of the
abrasive paper wheel, and then the abrasion loss is weighed through the electronic scale. And the
wear resistance of the piston sealing ring can be accurately known.
