Description
Technical field
The utility model relates to technical field of motors, in particular to a kind of spheroidal graphite carbon brush frame for motor.
Background technology
Ball mill is after material is broken, carry out the key equipment pulverized again, existing ball milling carbon brush for electric machine often sparkles, collector ring is burnt out, cause rough surface uneven, because collector ring hardness is high, be not easy process, even if after sand papering, the smoothness of collector ring is original so not good yet, but also can affect the useful life of new carbon brush, even the fault such as carbon brush holder, wire can be caused when striking sparks serious, when collector ring cannot repair use, only have to shut down and changed, the serious running rate that have impact on ball mill; But change carbon brush and collector ring not only costly frequently, and Workshop Production running rate can be affected due to shutdown.
Utility model content
The purpose of this utility model is to provide a kind of spheroidal graphite carbon brush frame for motor to reach the running rate reducing spark phenomenon between spheroidal graphite brush and collector ring, improve ball mill, solves that existing ball mill carbon brush often sparkles, collector ring easy burn-out, problem that ball mill running rate is low.
For realizing the utility model object, the technical scheme of employing is: a kind of spheroidal graphite carbon brush frame for motor, is characterized in that, comprise carbon brush holder, and described carbon brush holder is provided with chute, is provided with the slide block matched with it in chute; Described slide block is provided with card interface and back-moving spring, and one end of described back-moving spring is connected with the bottom of chute, and the other end is connected with slide block; Described carbon brush holder is provided with carbon brush contact, and carbon brush contact is provided with lead; Described carbon brush holder is provided with fixed block, fixed block is provided with the through hole matched with lead, lead is slidably arranged in through hole, lead is provided with rubber air mattress, stage clip is provided with in rubber air mattress, compression spring sleeve is in the outside of lead, and one end of described stage clip is connected with carbon brush contact, and the other end is connected with fixed block.
Further, described card interface is set to rectangular-shaped.
Further, described chute is positioned in the symmetric position of carbon brush holder, and described chute is set to T-slot.
The beneficial effects of the utility model are, adopt spheroidal graphite carbon brush frame for motor tool of the present utility model to have the following advantages: the fixed form 1, adopting slide block plug-in, relative to being threaded or welding, fixing more firmly and also dismounting also convenient; 2, carbon brush contact is provided with stage clip and rubber air mattress, can provide more stable pressure for carbon brush, avoids that friction spark occurs between carbon brush and collector ring and damages collector ring, save the production cost of factory; 3, improve the useful life of ball milling carbon brush for electric machine and collector ring, decrease maintenance load, improve the running rate of ball mill.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of spheroidal graphite carbon brush frame for motor that the utility model provides;
Fig. 2 is the A-A direction view of a kind of spheroidal graphite carbon brush frame for motor that the utility model provides.
Embodiment
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Fig. 1 and Fig. 2 illustrates the structural representation of a kind of spheroidal graphite carbon brush frame for motor that the utility model provides, and comprises carbon brush holder 3, and described carbon brush holder 3 is provided with chute 12, is provided with the slide block 2 matched with it in chute 12; Described slide block 2 is provided with card interface 10 and back-moving spring 7, and back-moving spring 7 is for the reset after slide block 2 and motor clamping; Described back-moving spring 7 one end is connected with the bottom of chute 2, and the other end is connected with slide block 2; Described carbon brush holder 3 is provided with carbon brush contact 5, and carbon brush contact 5 is provided with lead 1, and lead 1 prevents flashing between carbon brush contact 5 double swerve and collector ring, damages collector ring; Described carbon brush holder 3 is provided with fixed block 6, fixed block 6 is provided with the through hole 13 matched with lead 1, lead 1 is slidably arranged in through hole 13, lead 1 is provided with rubber air mattress 9, slip and the reset of rubber air mattress 9 pairs of leads 1 have cushioning effect, ensure that carbon brush contact 5 contacts with the normal of collector ring, avoid producing spark, in rubber air mattress 9, be provided with stage clip 8; One end of described stage clip 8 is connected with carbon brush contact 5, and the other end is connected with fixed block 6.
Stage clip 8 is enclosed within the outside of lead 1, and this structure is more conducive to the stability of stage clip 8, and the elasticity of stage clip 8 pairs of rubber air mattresses 9 recovers to have supplemental force simultaneously.
Card interface 10 is set to rectangular-shaped, and card interface 10 can also be set to toroidal or other analogous shape.
Chute 12 is positioned in the symmetric position of carbon brush holder 3, described symmetric position is carbon brush holder 3 is in the symmetric position of four centers, limit, chute 12 is set to T-slot, T-slot has structural pulling force to structure to slide block 2, this pulling force is used for fixed carbon brush holder 3, T-slot can also be replaced by other similar structures, can be formed and form fixing pulling force to carbon brush holder 3.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
