DEVICE FOR FORMING WEAR-RESISTANT AND ANTIFRICTION COATINGS OF PARTS SURFACE Russian patent published in 2015 - IPC C23C26/00 

FIELD: machine building.

SUBSTANCE: device for forming wear-resistant and antifriction coatings of parts surface contains bedplate with table made with possibility of the treated part installation and securing, device for process liquid supply, control panel, drives of rotating and progressive movements of the spindle, power cylinder, tool assembly secured on the spindle and containing casing in which the expanding cone, top support cone and bottom support cone, plungers and shoe with fixed in them rubbings are installed. In the shoes bronze and brass rubbings are installed, the tool assembly contains gear monitoring position of the bronze and brass rubbings, its use ensures possibility of neutral or work positions of the rubbings relatively to the treated surface of the part. Possibility of transition and holding of the bronze and brass rubbings in neutral position is ensured by top and bottom ring springs. In casing of the tool assembly along the longitudinal axis a top cylindrical cavity with cut through radial groove, and bottom cylindrical cavity are made, in its cavity in the casing radial holed are drilled. The expandable casing in top part is connected with rod passing through the top cylindrical cavity and bottom cylindrical cavity. On the rod the top and bottom support cones are secured.

EFFECT: increased level of mechanization and automation of the finish machining processes, increased productivity of the process upon reduced labour intensity, increased accuracy of the machined surface and cleanness of the machined surface.
