DEVICE FOR DETERMINING ROUGHNESS, MICROMECHANICAL AND TRIBOTECHNICAL PROPERTIES OF SURFACE MATERIAL OF ARTICLES Russian patent published in 2020 - IPC G01B21/30 G01N3/40 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, particularly, to devices for control of parameters of roughness and mechanical properties of cylindrical and flat friction surfaces of machine building items. Device comprises a solid base with positioners with drives installed on it, a post with a product holder, a set of replaceable indenters, as well as a control unit including a computer with software and controllers, part movement sensors in three spatial coordinates X, Y and Z and axial rotation. Device additionally includes five linear positioners with displacement sensors, a pole with a motorized rotary holder of the article with a rotation angle sensor, two optical confocal probes, an optical microscope and an indentation module. At first of linear positioners there is a three-coordinate positioner-piezoscanner with the possibility of its movement along horizontal axis Y, on which one indentation module is fixed with pyramidal or spherical indenter or in set with confocal probe. Second and the third linear positioners are made one on the other and the second confocal probe and the optical microscope are fixed on the top, which are movable along horizontal axes X and Y. On the fourth linear positioner there is a rotary post with the possibility of movement along axis X. Fifth linear positioner is installed on rack and allows to move motorized swivel holder of article along vertical axis Z. Post can be fixed on linear positioner in two positions relative to positioner parallel to its displacement axis or perpendicular to it.

EFFECT: providing measurement of parameters of nano-, micro-roughness and texture (regular microrelief) of the surface, as well as adhesion of coatings, tribotechnical characteristics and mechanical properties of material of flat and cylindrical surfaces of articles.
