Problems solved by technology

[0003] In the process of simulating the cutting state between the blade and the substrate through the pin-on-disk friction test, on the one hand, the pressure between the substrate and the blade cannot be adjusted, and it is impossible to simulate the real situation between the blade and the substrate under different pressures. Cutting state; on the other hand, due to the limitation of process precision, there are subtle bumps on the surface of the friction disc, so that when the friction pin and the friction disc are in high-speed relative rotation, the friction pin is likely to jump on the friction disc, affecting the final Observation of test results

Embodiment Construction

[0022] like Figure 1 to Figure 3 Shown, a kind of pin-on-disk friction testing machine of the present invention comprises a rectangular hollow test bench 1, is provided with on the table top of test bench 1 the friction disk 12 and friction pin 11 that are used to carry out friction test, the pin of friction pin 11 The friction test was carried out by contacting the head part with the disc surface of the friction disc 12 . During the friction test, the friction disc 12 is driven to rotate by the driving device 17 arranged inside the test bench 1, and the friction pin 11 remains stationary. The pressure and position adjustment device between the discs 12.

[0023] In this embodiment, the friction disc 12 is fixedly arranged in the holder, and the holder includes a lower end cover 16 with a step and a bolt that is fixedly connected with the lower end cover 16 and is used to press the friction disc 12 tightly on the step of the lower end cover 16. The annular upper end cover 1...

Abstract

The invention relates to the field of friction test equipment, in particular to a pin disk friction tester which comprises a test bench. A friction disk and a friction pin for friction test are arranged on a table of the test bench, the friction disk is driven to rotate by a driving device arranged in the test bench, and the friction pin is connected onto an adjusting device which is fixed onto the test bench and used for adjusting the pressure and positions of the friction pin and the friction disk. The pressure between the friction disk and the friction pin can be conveniently adjusted, andbounce of the friction pin on the friction disk due to process precision can be overcome.

Description

technical field [0001] The invention relates to the field of friction testing equipment, in particular to a pin-on-disk friction testing machine. Background technique [0002] In the field of lathe cutting, the friction between the blade and the substrate can easily lead to damage to the blade, and the cutting surface of the substrate is too rough to meet the technical requirements. Generally, it is necessary to use a friction test to determine which material the blade is most suitable for the cutting operation of a certain substrate, or what kind of lubricating oil is used to reduce the friction between the blade and the substrate during the cutting process. [0003] In the process of simulating the cutting state between the blade and the substrate through the pin-on-disk friction test, on the one hand, the pressure between the substrate and the blade cannot be adjusted, and it is impossible to simulate the real situation between the blade and the substrate under different ...
