Abstract
The utility model discloses a composite carbon brush used by an electric polishing machine, and the composite carbon brush comprises a carbon body, a left guide line, a right guide line, and an insert sheet including a clamping head, a contact pin, and binding posts, one end of the left guide line and one end of the right guide line are buried inside the carbon body, the insert sheet clamps the left guide line and the right guide line through the clamping head, the clamping head is directly connected with the contact pin, one side of the contact pin is provided with two binding posts and the contact pin side and the clamping head are vertical to each other, the carbon body comprises two symmetrical carbon blocks including a left carbon block and a right carbon block, a bonding layer is arranged between the two carbon blocks, and the two carbon blocks are bonded to a whole body through the bonding layer. The composite carbon brush used by the electric polishing machine uses the insert sheet to replace a conventional joint, the insert sheet is provided with two binding posts, the binding posts can firmly clamp motor guide lines, and functions of fixing the carbon brush and conducting electricity are simultaneously realized; and an insulation bonding layer is added in the carbon body, so commutation performance of the carbon brush is improved.
Description
Technical field
The present invention relates to a kind of carbon brush, especially a kind of carbon brush for electric polisher.
Background technology
Carbon brush is the device of transferring energy or signal between the standing part of motor or generator or other rotating machineries and the rotating part, in the time of electric machine rotation, electric energy is flowed to coil by 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 makes, and external form generally is square, and volume varies, and has wire to draw on the top, and wire is connected with joint.General wire is welded on the joint, and the joint another side then is fixed on the brush nest by spring, and the pressure that spring is fixed is less, and electric polisher using time body tremor amplitude is very large, and joint is easy to from motor break away from, and affects machine operation; When motor runs up, because the thermal coefficient of expansion of carbon brush is less, easily cause the card brush, cause motor commutation unstable.
Summary of the invention
The technical problem to be solved in the present invention provides the carbon brush that the stable suitable electric polisher that commutates of a kind of energy is used.
For solving the problems of the technologies described above, the technical scheme that the present invention takes is: the compound carbon brush of a kind of electric polisher, comprise the carbon body, left wire, right wire and inserted sheet, inserted sheet comprises clipper joint, contact pin and binding post, left wire and right wire one end are embedded in the carbon body, inserted sheet is in the same place left wire and right wire clamp by clipper joint, 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, described carbon body comprises the left carbon piece of the carbon piece of two symmetries and right carbon piece, be provided with adhesive layer between two carbon pieces, two carbon pieces are bonded into an integral body by adhesive layer.
As further improved technical scheme of the present invention, described adhesive layer is the insulation glue-line.
As further improved technical scheme of the present invention, described carbon body is cuboid.
As further improved technical scheme of the present invention, be provided with 4 chamferings on the described carbon body, 4 chamferings are separately positioned on four long limits of carbon body.
As further improved technical scheme of the present invention, described left and right sides wire is copper litz wire.
As further improved technical scheme of the present invention, described inserted sheet material therefor is brass.
The present invention replaces traditional joint with inserted sheet, at inserted sheet two binding posts is set, and binding post can firmly be clamped motor wire, plays simultaneously the fixedly effect of carbon brush and conduction; In the middle of the carbon body, add the insulation glue-line, can improve the commutation ability of carbon brush; Also be provided with chamfering at the carbon body, can allow the carbon body better contact with commutator, thereby improve motor performance.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Referring to Fig. 1, the compound carbon brush of this electric polisher comprises carbon body 1, left wire 2, right wire 3 and inserted sheet 4, and left wire 2 and right wire 3 one ends are embedded in the carbon body 1, and the wire degree of depth of sunkening cord in the left and right sides is 3.2mm, and extension elongation is 28mm, and sectional area is 0.5mm
2Insert, 4 comprise clipper joint 41, contact pin 42 and binding post 43, inserted sheet 4 by clipper joint 41 with left and right sides wire clamp together, clipper joint 41 directly links to each other with contact pin 42, be furnished with two binding posts 43 with clipper joint 41 mutually perpendicular one side in the contact pin 42, described carbon body 1 comprises the left carbon piece 11 of the carbon piece of two symmetries and right carbon piece 12, be provided with insulation glue-line 13 between two carbon pieces, two carbon pieces are bonded into an integral body by insulation glue-line 13, four long limits are respectively arranged with 4 chamferings on the carbon body, and wire adopts copper litz wire, and inserted sheet is that brass is made.The carbon body is fixed on the carbon brush holder during use, and the wire that the binding post of inserted sheet will be brushed in the nest is clamped, and can play simultaneously the fixedly effect of carbon brush and conduction; In the middle of the carbon body, add the insulation glue-line, can improve the commutation ability of carbon brush.
