Collection electrical slip ring coping instrument

The utility model discloses a collection electrical slip ring coping instrument is applied to motor technical field, include: at least one grinding apparatus, grinding apparatus bracket, bearer carrier, the grinding apparatus bracket is fixed on the bearer carrier, and the grinding apparatus bracket includes bracket dustcoat and closing device, and closing device connects on the bracket dustcoat, and the grinding apparatus is installed in the bracket dustcoat, and grinding apparatus front end protrusion in bracket dustcoat, and the grinding apparatus is located transmission the place ahead of closing device, and closing device presses the grinding apparatus to an album electrical slip ring. A problem for working as during the rotatory operation of collection electrical slip ring, carry out online coping to the collecting ring, can avoid the oxidation part to form a crude oxide film in an album electrical slip ring surface accumulation for a long time, and then the technical problem who avoids crude oxide film to cause brush and collection electrical slip ring contact failure, guarantee that synchronous machine's rotor excitation system runs well for a long time, also solved current repair method work load big with degree of difficulty height.
