DEVICE FOR ELECTROSPARK FORMATION OF COATINGS Russian patent published in 2022 - IPC B23H9/00 B23H7/26 

FIELD: engineering.

SUBSTANCE: invention relates to the field of formation of coatings by the method for electrospark alloying and can be used in various branches of engineering. The device contains an electrode installed in the cavity of the electrode holder connected to the source of the cooling agent and made with the possibility of reciprocating movement with the electrode and connection to the power supply wire using a terminal fixed by means of a threaded connection. The device contains an air motor and a head fixedly connected to the air motor housing, on which the LED is mounted. The electrode holder is rigidly connected to the link having an elliptical hole, the major axis of which is perpendicular to the direction of its movement. At the end of the air motor shaft, a cylindrical pin is rigidly fixed, the center of which is displaced relative to the axis of the air motor shaft by an eccentricity value and which is configured to move inside the said elliptical hole when the air motor shaft rotates. The link is made of steel and contains two elongated guide holes, which are oriented with their long side along the direction of movement of the link and into which two guiding cylindrical pins are threaded, symmetrically located relative to the center of the air motor shaft and fixed on the surface of the head.

EFFECT: reciprocating movement of the backstage is provided without the need to form a groove in the head and without the use of a ball bearing, as well as the reliability of the current supply and the light-dynamic protection against the pulsed impact of electric current discharges on the operator's eyes and the illumination of the coating formation zone on the surface of the part in the zone of its contact with the electrode.
