Sliding resistance testing mechanism in universal material testing machine

Abstract

The invention belongs to the technical field of detection equipment and provides a sliding resistance testing mechanism in a universal material testing machine. The sliding resistance testing mechanism comprises a testing platform and an adjusting device arranged below the testing platform. A testing region used for being matched with window glass is arranged in the middle of the testing platform. The window glass is suspended in the testing region. A product fixing part for containing a car sealing strip is arranged on the testing platform. A thread pitch adjusting device for adjusting the interval between the car sealing strip and the window glass is arranged on one side of the product fixing part. Ball bearing guiding devices in sliding fit with the window glass are arranged on the two sides of the testing region. The sliding resistance testing mechanism has the advantages that the sliding resistance testing mechanism can be directly assembled with the universal material testing machine and is high in universality, the window glass is fixed in a suspended mode, the glass is guided by ball bearings during sliding, no guide post or guide sleeve is arranged, the influences of friction force generated by a guide post and guide sleeve device on the experimental result are effectively eliminated, and it can be guaranteed that the mechanism is stable and reliable during tests.

Description

technical field [0001] The invention belongs to the technical field of testing equipment, and relates to a sliding resistance testing mechanism in a universal material testing machine. Background technique [0002] Automobile water cut is also called automobile sealing strip, which mainly plays the role of sealing and shock absorption. Before use, the automobile water cut needs to test its various performances. Among them, the sliding friction between the automobile water cut and the window glass is the measure of the automobile water cut performance. An important indicator, the measurement of the sliding friction between the existing general-purpose automobile sealing strip and the window glass is carried out on a universal material testing machine. However, the existing sliding resistance test mechanism cannot be tested on the universal material testing machine, or the guide post guide sleeve device cooperates with the window glass, and the friction generated has a great i...

However, the existing sliding resistance test mechanism cannot be tested on the universal material testing machine, or the guide post guide sleeve device cooperates with the window glass, and the friction generated has a great influence on the test results. Therefore, for the existing In the case of no device for the test, it is necessary to design an integrated sliding resistance test mechanism that can be directly assembled to the universal material testing machine for testing
