Abstract

The utility model discloses a generator electric brush radian polishing machine which comprises a static support wheel, a dynamic polishing wheel and a plurality of electric brush supports. The static support wheel and the dynamic polishing wheel are matched with each other, and the electric brush supports are erected between the static support wheel and the dynamic polishing wheel in parallel and used for containing electric brushes for operation and electric brushes to be polished; abrasive paper is arranged on the dynamic polishing wheel in the circumferential direction, and a handle is further arranged on the dynamic polishing wheel. The electric brushes to be polished are placed at the positions corresponding to the electric brushes in operation, the abrasive paper is used for conducting polishing to enable the radians of the electric brushes to be polished to be coincident with the radians of the electric brushes in operation, the electric brushes matched with a generator rotor are accordingly obtained, and the problems of electric brush overheating caused by poor contact of the electric brushes, fire striking between the electric brushes and sliding rings and the like are solved.

Description

A kind of generator brush radian sander
Technical field
The utility model relates to a kind of sander, is specifically related to a kind of generator brush radian sander.
Background technology
Brush is for commutator or slip ring, and as the sliding-contact body that imports and exports electric current, nearly all direct current generator and commutating machine all use brush, and it is the important composition parts of motor.In the course of the work, brush inevitably can wear and tear generator, in the time finding that brush wear is serious in running, need to change timely.Brush need to be polished in the time changing, and polishing can not too much can not be very few, and the too much words of polishing easily cause brush to rock in brush carrier, and very cracky also can cause contact-making surface too small and generate heat, polish easily cause again brush to expand when very few after bite.
Generation current electromechanical brush is polished without special tool utensil, can only find the equipment of similar generator rotor ring radian to polish, so just cause actual radian and the generator amature radian of brush to have deviation, cause the phenomenon of loose contact, thereby will cause generator brush to occur following problem: 1. contact resistance becomes large, and exciting current reduces; 2. make brush and slip ring overheated, when serious, can catch fire; 3. between brush and slip ring, strike sparks, cause slip ring generation galvanic corrosion, wearing and tearing increase.
Utility model content
The purpose of this utility model is to overcome above-mentioned defect of the prior art, provides a kind of and can exactly new brush be polished into and the on all four generator brush radian of the brush radian sander that needs replacing in service.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of generator brush radian sander, comprises the static rack wheel that matches and dynamic grinding wheel, and parallel multiple brush holders that set up between the two, and brush holder is for placing operation brush and brush to be polished; Dynamically grinding wheel week be upwards provided with sand paper, dynamically in grinding wheel, be also provided with handle.
On described brush holder, place operation while use brush, be as the criterion with brush less than operation with dynamic grinding wheel polishing, and place wait polish brush time, brush to be polished fits tightly with dynamic grinding wheel.
Describedly rotate dynamic grinding wheel by handle, dynamically grinding wheel drives sand papering brush to be polished, and its radian is polished into to move radian with brush consistent.
Described is upwards provided with sand paper draw-in groove in dynamic grinding wheel week, and sand paper is arranged in sand paper draw-in groove, and strains by sand paper take-up device.
Described static rack wheel bottom is provided with the bracing frame of fixing use, and static rack wheel is connected with dynamic grinding wheel concentric by bearing grease chamber.
Described static rack wheel is fixed on locker, and described locker comprises finished product Split charging box and spare unit cabinet.
Compared with prior art, the utlity model has following useful technique effect:
The generator brush radian sander that the utility model provides, by the static rack wheel and the dynamic grinding wheel that match, and the parallel brush holder setting up, brush to be polished is placed on to the position corresponding with operating brush, by dynamic grinding wheel, operation is weighed with the radian of brush and brush to be polished, make both radians consistent by sand papering, thereby obtain the brush more mating with generator amature, avoid occurring the problems such as spark phenomenon between the brush that causes because of brush loose contact overheated and brush and slip ring.
The generator brush radian sander that the utility model provides, because dynamic grinding wheel is provided with sand paper draw-in groove and sand paper take-up device, makes sand paper in dynamically fixing more the compacting of grinding wheel outer surface, polishing better effects if.
The generator brush radian sander that the utility model provides, because static support is directly fixed on finished product Split charging box and spare unit cashier's office in a shop, makes to get thing and stores more fast, is convenient to polishing in batches.
Accompanying drawing explanation
Fig. 1 structural representation of the present utility model;
Wherein: 1. static rack wheel; 2. bearing grease chamber; 3. brush holder; 4. sand paper; 5. dynamic grinding wheel; 6. sand paper take-up device; 7. sand paper draw-in groove; 8. handle; 9. bracing frame; 10. finished product Split charging box; 11. spare unit cabinets.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, described in be to explanation of the present utility model rather than restriction.
Referring to Fig. 1, a kind of generator brush radian sander, is characterized in that, comprises the static rack wheel 1 that matches and dynamic grinding wheel 5, and parallel multiple brush holders 3 that set up between the two, and brush holder 3 is for placing operation brush and brush to be polished; Dynamically grinding wheel 5 week be upwards provided with sand paper 4, dynamically in grinding wheel 5, be also provided with handle 8.
Further, on described brush holder 3, place operation while use brush, polish and be as the criterion less than operation brush with dynamic grinding wheel 5, and place wait polish brush time, brush to be polished fits tightly with dynamic grinding wheel 5.Rotate dynamic grinding wheel 5 by handle 8, dynamically grinding wheel 5 drives sand paper 4 brush to be polished of polishing, and its radian is polished into to move radian with brush consistent.
Concrete, described dynamic grinding wheel is upwards provided with sand paper draw-in groove 7 for 5 weeks, and sand paper 4 is arranged in sand paper draw-in groove 7, and strains by sand paper take-up device 6.
Described static rack wheel 1 bottom is provided with the bracing frame 9 of fixing use, and static rack wheel 1 is connected with dynamic grinding wheel 5 concentrics by bearing grease chamber 2.
Described static rack wheel 1 is fixed on locker, and described locker comprises finished product Split charging box 10 and spare unit cabinet 11.
Described generator brush radian sander is in the time carrying out the polishing of brush, first finished product brush is placed on the position corresponding with moving brush, be as the criterion with brush less than operation with dynamic grinding wheel polishing, and place wait polish brush time, brush to be polished fits tightly with dynamic grinding wheel, be rotatably connected on the handle in dynamic grinding wheel, thereby utilize sand paper to carry out hand sand to brush, finished product brush is polished into the brush consistent with brush radian in service; In the time that brush radian can not mate completely with dynamic grinding wheel radian, can progressively mate to carry out complete polishing with a bit of radian.
Generator brush radian sander of the present utility model, it is simple in structure, easy to operate, can exactly new brush be polished into and the on all four radian of brush that needs replacing in service, thereby avoid bringing potential safety hazard to slip ring, brush.
