Tester used for testing abrasion resistance of abrasion-resistant layers of automotive rubber strips

Abstract

The invention discloses a tester used for testing abrasion resistance of abrasion-resistant layers of automotive rubber strips. The tester comprises a load bearing platform, a rubber strip grinding device and a driving system, wherein pressing plates used for fixing to-be-tested rubber strips are respectively arranged at two ends of the load bearing platform; the rubber strip grinding device fixed above the load bearing platform by virtue of a bracket comprises a guide sleeve mounted on the bracket, a sliding shaft arranged inside the guide sleeve in a manner of sliding up and down, a counterweight loaded above the sliding shaft and a grinding head arranged under the sliding shaft; the driving system is used for driving the load bearing platform to move forth and back relative to the grinding head, so that to-and-fro sliding friction is formed between the grinding head and the to-be-texted rubber strips; the driving system comprises a rocker arm speed reduction motor, a motor connection rod, a power supply module, a counter, a relay connected with the power supply module and the counter, and a rotation speed regulating module which is connected between the relay and the rocker arm speed reduction motor; the relay is used for controlling connection or disconnection of the relay according to the counted number of the counter so as to control the operation of the motor.

Description

technical field [0001] The invention relates to a wear-resistant testing machine, in particular to a testing machine for carrying out wear-resistant tests on the wear-resistant layer of rubber strips for vehicles. [0002] Background technique [0003] After producing the rubber strips for vehicles and before leaving the factory, manufacturers need to conduct various tests on the rubber strips for vehicles. One of the tests is to test the wear-resistant layer of the rubber strip to check whether the wear-resistant property of the rubber strip meets the national standard. At present, some manufacturers are still very backward in the detection methods of rubber strips for vehicles, and cannot even perform automatic testing on the rubber strips, and the friction force cannot be changed randomly when testing the rubber strips, etc. Even if some individual manufacturers have designed wear-resistant equipment to detect vehicle rubber strips, these equipment are either large in s...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art above, the technical problem to be solved by the present invention is: to provide a testing machine for carrying out wear-resisting tests on the wear-resistant layer of rubber strips for vehicles, which solves the problem that the existing methods cannot The automatic test of rubber strips and the inability to randomly change the friction force of rubber strips for vehicles, etc., the present invention can drive the bearing platform to move back and forth relative to the grinding head through the drive system, and can pre-set the number of times of friction rubber strips, when the test After the machine reaches the preset number of times, it will automatically stop working; the position arrangement of each part of the testing machine is very compact and reasonable, which makes the whole testing machine miniaturized, saves raw materials, and is convenient to move
