Description
Technical field
The utility model belongs to generating equipment technical field.
Background technique
Carbon brush is also brush, as a kind of slide contact member, in many electrical equipments
It is widely used.Material mainly has graphite, soaks rouge graphite, metallic graphite carbon etc..
Generator carbon brush is to transmit electric energy between generator fixed system and rotation system
Device, shape is cuboid, be installed in the brush carrier on brush holder, cooperation spring be pressed on collector ring,
Main function is conducted exciting current to rotor.Main component is carbon, easy to wear, and periodic maintenance is needed to replace.
Carbon brush must more be renewed when carbon brush abrasion is to 2/3, new carbon brush and collector ring are line
Contact, less than the 3/4 of whole contacts area, it is necessary to polish carbon brush contact surface.Traditional work is used at present
Skill is correctly to install carbon brush, and a thin glass paper, under normal spring pressure, edge are placed between carbon brush and collector ring
Carbon brush is ground in collector ring direction of rotation, and sand paper clings collector ring as far as possible, cleaned up after qualified with compressed air and alcohol etc..
When polishing second-rate, it may appear that current distribution is uneven is even, sparking, overheats
Phenomena such as, influence generating set safe and stable operation.
Due to being influenced by carbon brush installation site, installation space is narrow, using traditional work
It is inconvenient for operation when skill replacement processing carbon brush, there is the danger of person electric shock；Polishing every time, even if wearing mask
It has in carbon dust sucking mouth and nose, is detrimental to health.
Utility model content
The purpose of this utility model is: providing a kind of generator carbon brush cambered surface grinding device, it can quick, high quality pair
Generator carbon brush reparation grinding.
The technical solution of the utility model is: arc shooting is fixed with several carbon brush fixtures, carbon on grinding plate top surface
The corresponding surface of brush clamp tool is fixed with grinder by grinder rack shaft, and grinder rear end is driven by universal joint and swing arm
Arm connection, swing arm driving motor are cooperated by swing arm actuating arm and swing arm transmission, and bucket shape powder is arranged below in grinder
Dirt collection box, dust collecting box are connected to by hose with dust catcher.
The beneficial effects of the utility model are: not only can use identical platform, by replace different carbon brush molds come
Grind different radian carbon brush.And harm caused by traditional handicraft is effectively avoided, and greatly improve working efficiency.
By the simple adjustment to device, it can be achieved that the grinding of any radian carbon brush.
Detailed description of the invention
Fig. 1 is the utility model electrical schematic diagram；
Fig. 2 is the utility model main view；
Fig. 3 is the utility model side view；
Fig. 4 is the utility model top view.
Specific embodiment
Embodiment 1
The utility model is described further with reference to the accompanying drawing:
As shown in Figure 1, it be indicator light, SB be button switch, CK be travel switch, XCQ is dust suction that QF, which is contactor, HL,
It is swing arm driving motor that device, JMJ, which are angle grinder, BJ,.
As shown in Figure 2,3, 4,1 be grinding plate, 2 be carbon brush mold, 3 be storage box, 4 be grinding machine support, 5 be grinding
Machine, 6 be dust collecting box, 7 be swing arm, 8 be grinder power supply line, 9 be dust catcher, 10 be connection hose, 11 be electric cabinet,
12 it is dust collecting box, 13 be carbon brush fixture, 14 be swing arm actuating arm, 15 be swing arm driving motor, 16 is handle.
The present apparatus uses 220V AC power source for electrical source of power, by control system,
Make grinding system according to reciprocally swinging is carried out in the hunting range of design, realizes the grinding of carbon brush.Device is divided into certainly
Dynamic and manual both of which, the switching of both of which can be realized by knob.Automatic mode: pass through the driving mechanism of grinding system
Realization device automatic grinding；Manual mode: the artificial grinding for pushing swing arm to realize carbon brush.
Utility model device is mainly made of following several systems:
Grinding plate, control system, grinding system, carbon brush mold, storage box, dust pelletizing system composition.
Grinding plate: platform base 1 is made by angle steel and insulation board etc..Bottom is equipped with 4 universal wheels, easy to remove.On
Portion is equipped with handle 16 and storage box 3, easy to remove and storage specific purpose tool, device accessory etc..Platform divides upper and lower level, upper layer installation
Grinding system, mold location hole etc., lower layer are equipped with the hanging position of dust pelletizing system, control system and carbon brush mold 2.
Grinding system: by grinder 5, grinding machine support 4, swing arm driving motor 15, swing arm actuating arm 14, swing arm
7, shop bolt and support member composition, main function are to drive swing arm to move back and forth by driving motor according to operational order,
To drive angle grinder to grind carbon brush by regulation plate degree；Swing arm and grinding plate surface are sliding friction, not set pulley dress
It sets.
Dust pelletizing system: it is made of dust catcher 9, connection hose 10, dust collecting box 6 etc., main function is that collection is ground
The dust generated in journey.
Control system: control cabinet 11 is made of cabinet, governor, control-rod, motor etc., and main function is control grinding system
System and dust pelletizing system, realize the collection of the automatic grinding and dust of carbon brush.
Carbon brush mold: it is made of brush carrier, operating handle, brush carrier fixed plate, shop bolt, carbon brush arc template etc., mainly
Effect is fixed and adjustment carbon brush abrasion amount, guarantees that each carbon brush is ground according to the radian and abrasion loss of design.
The course of work
1. correct select required carbon brush mold, and alignment finger follows closely position, is fixed securely with bolt；
2. the carbon brush ground will be needed to be mounted on corresponding brush carrier, carbon brush is adjusted with corresponding carbon brush arc template
Reserved abrasion loss, after be tightened bolt；
3. checking grinding system swing arm in initial position, dust pelletizing system position is correct, adjusts the speed knob in low-speed position；
4. powering on, automatic (manual) knob is operated, mode needed for selecting presses start button, and device is started to work；
It has been ground to required radian 5. checking, has pressed stop button；
6. removing the carbon brush that grinding is completed is placed into designated position, spare.
