Abstract
The invention discloses a porous carbon brush for an electric pick. The porous carbon brush for the electric pick comprises a carbon body, a wire, a connecting spring, a contact piece and a copper bush, two symmetrical protrusions are arranged on the side face of he upper portion of the carbon body, the upper portion of the carbon body is sleeved with the copper bush, the copper bush is clamped on the carbon body through the two symmetrical protrusions, a protruding cylindrical boss is arranged on the copper bush, one end of the connecting spring is fastened to the contact piece, the other end of the connecting spring wraps the cylindrical boss of the copper bush and is in contact with the copper bush, one end of the wire is welded to the contact piece, and the other end of the wire penetrates through the connecting spring and is connected with the copper bush. At least two through holes are formed in the carbon body, and the direction of each through hole is parallel to the wire. According to the porous carbon brush for the electric pick, the carbon body is sleeved with the copper bush, the wire is led from the copper bush, together with the wire on the copper bush, the spring and the contact piece can be used repeatedly, and therefore cost and environmental pollution are reduced; the through holes are formed in the carbon body to enable the heat of the carbon brush to be well radiated, and therefore the smooth operation of a motor is guaranteed.
Description
?
Technical field
The present invention relates to a kind of carbon brush, in particular for the carbon brush of electric hammer.
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 rotating part, in the time of electric machine rotation, electric energy is flowed to coil by phase changer.Carbon brush, as a kind of sliding contact part, is widely used in many electric equipments.Traditional carbon brush is generally that pure carbon adds coagulating agent and makes, and external form is generally square, and volume varies, and on top, has wire to draw, and wire bonds is on joint, and the joint another side is fixed on the brush nest by linking springs.When motor runs up, thereby carbon brush can produce heat by the high speed vibration, and, because the space between carbon body and carbon brush sleeve is minimum, heat is not easy to distribute, and carbon brush can produce temperatures involved machine operation performance; After the wearing and tearing of carbon body, carbon brush all must all be changed together with the wire on carbon brush, spring and joint, and wire, spring and joint are all to be made by heavy metal, can cause environmental pollution after abandoning, and are unfavorable for environmental protection and saving.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of electric pick porous carbon brush that needs to change the carbon body.
For addressing the above problem, the technical solution used in the present invention is: a kind of electric pick porous carbon brush, comprise the carbon body, wire, linking springs and contact pin, also comprise copper sheathing, carbon body upper side has the protrusion of two symmetries, copper sheathing is enclosed within carbon body top, by the protrusion of two symmetries, be stuck on the carbon body, the cylindrical boss that one protrusion is arranged on copper sheathing, one end of linking springs is fixed in contact pin, cylindrical boss on other end parcel copper sheathing also contacts with copper sheathing, one end of wire is welded in contact pin, the other end is connected with copper sheathing through linking springs, be provided with at least 2 through holes on the carbon body, the direction of through hole is parallel with wire.
As a modification of the present invention, described wire is copper core flexible cord.
As a modification of the present invention, described contact pin is latten(-tin).
The present invention puts a copper sheathing on the carbon body, wire is drawn from copper sheathing, do not affect like this function of carbon brush, when carbon brush abrasion needs to change to a certain extent, only needing to change the carbon body gets final product, copper sheathing is all reusable together with top wire, spring and contact pin, not only reduces costs, and environmental contamination reduction; The protrusion of two symmetries that design on the carbon body can tightly be stuck in copper sheathing on the carbon body, and during use, copper sheathing is unlikely comes off; Be provided with through hole in the carbon body, can allow carbon brush better dispel the heat, guarantee that motor runs well.

The accompanying drawing explanation
Accompanying drawing 1 is generalized section of the present invention.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention will be further described.
This electric pick porous carbon brush, comprise carbon body 1, wire 2, linking springs 3 and contact pin 4, also comprise copper sheathing 5, carbon body 1 upper side has the protrusion 6 of two symmetries, copper sheathing 5 is enclosed within carbon body 1 top, by the protrusion 6 of two symmetries, be stuck on carbon body 1, the cylindrical boss 7 that one protrusion is arranged on copper sheathing 5, the high 5mm of cylindrical boss, one end of linking springs 3 is fixed in contact pin 4, cylindrical boss 7 on other end parcel copper sheathing 5 also contacts with copper sheathing 5, one end of wire 2 is welded in contact pin 4, the other end is connected with copper sheathing 5 through linking springs 3, be provided with 2 through holes 8 on carbon body 1, the direction of through hole 8 is parallel with wire 2, wire is copper core flexible cord, contact pin is latten(-tin).This electric pick puts a copper sheathing on the carbon body with the porous carbon brush, wire is drawn from copper sheathing, do not affect like this function of carbon brush, when carbon brush abrasion needs to change to a certain extent, only need to change the carbon body and get final product, copper sheathing is all reusable together with top wire, spring and contact pin, not only reduce costs, and environmental contamination reduction, through hole be provided with in the carbon body, can allow carbon brush better dispel the heat, guarantee that motor runs well.
