Abstract
The utility model discloses a composite carbon brush for electric grinder, and the composite carbon brush for the electric grinder comprises a carbon body, a left connecting wire, a right connecting wire, and a lug plate, the carbon brush also comprises a left pipe sleeve and a right pipe sleeve, the carbon body comprises two symmetrical carbon blocks including a left carbon block and a right carbon block, and the two carbon blocks are bonded into a whole body through a bonding layer; one end of the left connecting wire and one end of the right connecting wire are respectively buried in the left carbon block and the right carbon block, the other ends of the connecting wires are welded on the lug plate, the left pipe sleeve and the right pipe sleeve respectively wrap portions of the left connecting wire and the right connecting wire exposed outside, and the lug plate is made of phosphor copper material. The composite carbon brush for the electric grinder wraps a layer of insulating sleeve pipe outside the wire, the carbon brush is insulated from conductive liquid, the sleeve pipes also can protect the connecting wires, so usage life of the carbon brush is prolonged; an insulating adhesive layer is added in the carbon body, so commutation performance of the carbon brush is improved; and the carbon brush employing the phosphor copper lug plate has a relatively good contact with a motor, the carbon brush can be used in a long term without deformation, thereby guaranteeing the motor to run steadily.
Description
Technical field
The utility model relates to a kind of carbon brush, especially a kind of carbon brush for electrical grinding machine.
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, external form generally is square, volume varies, there is wire to draw on the top, wire exposes outside often, and the part wire of carbon brush need to pass conducting liquid in electrical grinding machine, but carbon brush can not directly contact with conducting liquid, otherwise easily motor is burnt out, so traditional carbon brush is not suitable in the electrical grinding machine; When motor runs up, because the thermal coefficient of expansion of carbon brush is less, easily cause the card brush, cause motor commutation unstable; And contact pin is made with latten(-tin) often, and latten(-tin) has good ductility and conductivity, and is easy to process, but hardness is lower, and easily distortion affects motor performance after long-term the use.
The utility model content
The technical problems to be solved in the utility model provides the carbon brush that a kind of suitable electrical grinding machine is used.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: the compound carbon brush of a kind of electrical grinding machine, comprise carbon body, left connection wire, right connection wire and lug plate, also comprise left pipe box and right pipe box, 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; Left connection wire be connected an end of connection wire and be embedded in respectively in left carbon piece and the right carbon piece, the other end is welded on the lug plate, left pipe box be connected pipe box and wrap respectively left connection wire and be connected the exposed part outside of connection wire, described lug plate material therefor is phosphor-copper.
As the further improved technical scheme of the utility model, described adhesive layer is the insulation glue-line.
As the further improved technical scheme of the utility model, described left and right sides sleeve pipe is glass fibre sleeve.
As the further improved technical scheme of the utility model, described left and right sides sleeve pipe is the silica gel pipe box.
As the further improved technical scheme of the utility model, connecting wire about described is copper litz wire.
The utility model has wrapped up one deck insulating sleeve at wire, not only can allow carbon brush and conducting liquid insulate to protect motor, and sleeve pipe can also be protected the connection wire, prolongs the useful life of carbon brush; In the middle of the carbon body, add the insulation glue-line, can improve the commutation ability of carbon brush; Use the carbon brush of phosphor-copper lug plate better with contacting of motor, long-term use is not yielding, can guarantee that motor is stable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to Fig. 1, the compound carbon brush of this electrical grinding machine, comprise carbon body 1, left connection wire 2, right connection wire 3 and lug plate 6, also comprise left glass fibre pipe box 4 and right glass fibre pipe box 5, carbon body 1 comprises the left carbon piece 11 of the carbon piece of two symmetries and right carbon piece 12, be provided with adhesive layer 13 between two carbon pieces, adhesive layer 13 is the insulation glue-line, and two carbon pieces are bonded into an integral body by adhesive layer 13; Left connection wire 2 be connected an end of connection wire 3 and be embedded in respectively in left carbon piece 11 and the right carbon piece 12, the other end is welded on the lug plate 6, left glass fibre pipe box 4 be connected glass fibre pipe box 5 and wrap respectively left connection wire 2 and be connected the exposed parts outside of connection wire 3, left connection wire 2 be connected connection wire 3 and be copper litz wire, lug plate is phosphorus bronze sheet.Wherein also available silica gel pipe box is alternative for the glass fibre pipe box.In the present embodiment in the coated outside that connects wire one deck insulative, not only can allow carbon brush and conducting liquid insulate to protect motor, sleeve pipe can also be protected the connection wire, the useful life of prolongation carbon brush; In the middle of the carbon body, add the insulation glue-line, can also improve the commutation ability of carbon brush; Use the carbon brush of phosphor-copper lug plate better with contacting of motor, long-term use is not yielding, can guarantee that motor is stable.
