Abstract

The invention provides a friction and wear testing machine of guide rail of machine tool and relates to a friction and wear testing device of guide rail pair, belonging to the technological field of tribology. The testing device comprises a testing system and a measuring system. An oil blocking plate in the testing system is provided with an upper sample platform, an oil blocking plate, a lower sample platform, a first sensor mounting bracket and a second sensor mounting bracket; the first sensor mounting bracket and the second sensor mounting bracket are respectively arranged on a base; a flat V guide rail is arranged between the lower sample platform and the base; an upper sample fixture is arranged between the first sensor mounting bracket and the second sensor mounting bracket; the first sensor mounting bracket and the second sensor mounting bracket are connected with a cover plate respectively by a support rod. The novel friction and wear testing machine of the machine tool can simulate the actual working condition, and directly adopt the guide rail as the sample. Moreover, the testing machine can not only be used for rapidly assessing the material of the guide rail pair and the lubricating medium, but also can be used for the accelerated life test of the straight guide rail pair and the rolling guide rail pair.

Description

technical field [0001] The invention relates to a friction and wear test device for a guide rail pair, in particular to a V-shaped and Λ-shaped rolling steel guide rail and a linear guide rail friction and wear test device, and belongs to the technical field of tribology. Background technique [0002] Rolling guides have the advantages of high motion sensitivity, small friction, and stable low-speed motion. They are commonly used moving parts in machine tools. The linear rolling guides produced in recent years are widely used in the machine tool industry because of their low requirements on the installation reference plane and easy installation and adjustment. It has also been gradually promoted and applied. The service life of the guide rail has a direct impact on the machining accuracy and service life of the machine tool. After the machine tool has been used for a certain period of time, uneven wear of the guide rail surface, accompanied by fatigue pitting of the rolling...
