Description
Technical field
The invention belongs to generating equipment technical fields.
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, mainly
Effect 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.It is using traditional technique at present
Carbon brush is correctly installed, a thin glass paper is placed between carbon brush and collector ring, under normal spring pressure, along current collection
Carbon brush is ground in 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, has wearing mask
Carbon dust sucks in mouth and nose, is detrimental to health.
Summary of the invention
The object of the present invention is to provide a kind of generator carbon brush cambered surface grinding devices, it can be quick, high quality to power generation
Machine carbon brush reparation grinding.
The technical scheme is that arc shooting is fixed with several carbon brush fixtures, brush holder on grinding plate top surface
The corresponding surface of tool is fixed with grinder by grinder rack shaft, and grinder rear end is connected by universal joint and swing arm actuating arm
It connects, swing arm driving motor is cooperated by swing arm actuating arm and swing arm transmission, and bucket shape dust is arranged below in grinder and receives
Collect box, dust collecting box is connected to by hose with dust catcher.
The beneficial effects of the present invention are: not only can use identical platform, ground by replacing different carbon brush molds
Different radian carbon brush.And harm caused by traditional handicraft is effectively avoided, and greatly improve working efficiency.Pass through
Grinding, it can be achieved that any radian carbon brush is adjusted to the simple of device.

Fig. 2 is main view of the present invention；
Fig. 3 is side view of the present invention；
Fig. 4 is top view of the present invention.
Specific embodiment
Embodiment 1
The present invention 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 catcher, JMJ that QF, which is contactor, HL,
It is angle grinder, BJ is swing arm driving motor.
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 be divided into it is automatic and
Manual both of which can realize the switching of both of which by knob.Automatic mode: it is realized by the driving mechanism of grinding system
Device automatic grinding；Manual mode: the artificial grinding for pushing swing arm to realize carbon brush.
Apparatus of the present invention are 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, the pre- of carbon brush is adjusted with corresponding carbon brush arc template
Stay 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.
