Abstract

The utility model discloses a carbon brush for an electric polishing machine. The carbon brush comprises a carbon body, a connecting wire and an angle plug, wherein one end of the connecting wire is embedded into the carbon body; the angle plug is used for clamping the other end of the connecting wire by a line clamp head; the line clamp head is directly connected with an angle plug piece; and two line clamp columns are arranged on the one side, which is perpendicular to the line clamp head, of the angle plug piece. By the carbon brush, the traditional joint is replaced by the angle plug; two line clamp columns are arranged on the angle plug and can firmly clamp a wire of a motor so as to play roles in fixture of the carbon brush and electric conduction; and a chamfer is also formed on the carbon body, so that the carbon body is in well contact with a commutator; and therefore, the performance of the motor is improved.

Description

Electric polisher is used carbon brush

Technical field

The utility model relates to a kind of carbon brush, especially a kind of carbon brush that is used for electric polisher.

Background technology

Carbon brush is the device that transmits energy or signal between standing part and the rotating part of motor or generator or other rotating machineries, when motor rotates, electric energy is flowed to coil through phase changer.Carbon brush is widely used in many electric equipments as a kind of sliding contact part.Traditional carbon brush generally is that pure carbon adds coagulating agent and processes, and external form generally is a square, and volume varies, and has lead to draw on the top, and lead is connected with joint.General lead is welded on the joint, and the joint another side then is fixed on the brush nest through spring, and the spring fixed pressure is less, and electric polisher using time body tremor amplitude is very big, and joint is easy to from motor break away from, and influences machine operation.

The utility model content

The technical problem that the utility model will solve provides the carbon brush that a kind of suitable electric polisher is used.

For solving the problems of the technologies described above; The technical scheme that the utility model is taked is: a kind of electric polisher is used carbon brush; Comprise the carbon body, connect lead and the angle is inserted, connect lead one end and be embedded in the carbon body, said angle is inserted and will be connected the lead other end through the clamp head and clamp; The clamp head directly links to each other with the angle inserted sheet, one side the angle inserted sheet vertical with the clamp head be furnished with two clamp posts.

As the further improved technical scheme of the utility model, said carbon body is provided with 4 chamferings, and 4 chamferings are separately positioned on four long limits of carbon body.

As the further improved technical scheme of the utility model, said carbon body is a cuboid.

As the further improved technical scheme of the utility model, said connection lead is a copper litz wire.

As the further improved technical scheme of the utility model, it is brass that material therefor is inserted at said angle.

The utility model is inserted the traditional joint of replacement with the angle, plugs at the angle two clamp posts are set, and the clamp post can firmly be clamped the motor lead, plays the fixedly effect of carbon brush and conduction simultaneously; Also the carbon body is provided with chamfering, can let the carbon body better contact with commutator, thereby improves motor performance.
