Abstract
The utility model discloses a compound type carbon brush for an electric polishing machine. The compound type carbon brush comprises a carbon body, a left guide wire, a right guide wire and an insert sheet. The insert sheet comprises a clamp connector, a connection sheet and binding posts. One ends of the left guide wire and the right guide wire are embedded in the carbon body. The left guide wire and the right guide wire are clamped together through the clamp connector of the insert sheet. The clamp connector is directly connected with the connection sheet. Two binding posts are arranged on one side of the connection sheet and the side is perpendicular to the clamp connector. The carbon body comprises a left carbon block and a right carbon block which are symmetrical. A bonding layer is arranged between the left carbon block and the right carbon block. The two carbon blocks are integrated through the bonding layer. The insert sheet is made of phosphor copper materials. The insert sheet is used to replace a traditional connector and provided with two clamp connection posts which can tightly clamp wires of a motor and simultaneously have the functions of fixing the carbon brush and conducting electricity. An insulation adhesive layer is arranged in the middle of the carbon body so that reversing performance of the carbon brush is improved. The phosphor copper insert sheet is used on the carbon brush so that the carbon brush can better contact with the motor, and the phosphor copper insert sheet is not easy to deform in a long term and can guarantee stable operation of the motor.
Description
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; When motor runs up, because the thermal coefficient of expansion of carbon brush is less, cause the card brush easily, cause motor commutation unstable.And contact pin is processed with latten(-tin) often, and latten(-tin) has good ductility and conductivity, and is easy to process, but hardness is lower, and the long-term back easy deformation of using influences motor performance.
The utility model content
The technical problem that the utility model will solve provides the carbon brush that the stable suitable electric polisher that commutates of a kind of ability 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 compound carbon brush, comprises carbon body, left lead, right lead and inserted sheet; Inserted sheet comprises clipper joint, contact pin and binding post; Left side lead and right lead one end are embedded in the carbon body, and inserted sheet is in the same place left lead and right wire clamp through clipper joint, and clipper joint directly links to each other with contact pin; Be furnished with two binding posts with the mutually perpendicular one side of clipper joint in the contact pin; Said carbon body comprises the carbon piece left side carbon piece and the right carbon piece of two symmetries, is provided with adhesive layer between two carbon pieces, and two carbon pieces are bonded into an integral body through adhesive layer; Said inserted sheet material therefor is a phosphor-copper.
As the further improved technical scheme of the utility model, said adhesive layer is the insulation glue-line.
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 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 left and right sides lead is a copper litz wire.
The utility model is provided with two clamp posts with the traditional joint of inserted sheet replacement on inserted sheet, the clamp post can firmly be clamped the motor lead, plays the fixedly effect of carbon brush and conduction simultaneously; In the middle of the carbon body, add the insulation glue-line, can improve the commutation ability of carbon brush; Also the carbon body is provided with chamfering, can let the carbon body better contact with commutator, thereby improves motor performance; Use the carbon brush of phosphor-copper inserted sheet better with contacting of motor, long-term use is not yielding, can guarantee that motor is stable.
