A device for obtaining a regular microrelief on the mating surface of a part

摘要

The utility model refers to the tooling of metalworking machines and can be used to produce moth-eye oil-retaining grooves on the mating surfaces of parts in order to increase their wear resistance.;The device comprises a body with a tool carriage equipped with mechanisms for its reciprocating movement and adjustment of the amount of its reciprocating movement. The reciprocating mechanism of the carriage is made in the form of a drive faceplate on which, with an eccentricity with respect to the axis of rotation, an axle supporting two rolling bearings is mounted, one of which is mounted in the central part of the axis in the groove of the carriage and the other in the frame opening with the possibility contact with the wall of its opening, and the mechanism for adjusting the magnitude of the reciprocal movement of the tool carriage is made in the form of a tool carriage installed in the threaded hole with the possibility NOSTA adjusting movement of the adjusting screw, with the fifth at its end, placed in the area of ​​the groove of the tool carriage with the possibility of interaction with the bearing located in the groove. 4il.
