The present invention is further explained with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of electrolysis brush device, it by Electrolyzed Processing power supply 1, electrolyte system 2, electrolysis brush machine 3,
Machine tool system 4 forms, and the electrolyte system 2 is arranged in parallel in electrolysis brush machine 3 on machine tool system 4, the electrolysis brush
3 lower end of machine is equipped with workpiece 5, and the workpiece 5 connects 1 anode of Electrolyzed Processing power supply, and the electrolysis brush machine 3 connects Electrolyzed Processing electricity
1 cathode of source, the electrolysis brush machine 3 include live spindle 301 and cathode brush head 302, and the electrolyte system 2 is by electrolysis liquid pump
201, electrolytic bath 202, filter 203, cooler 204 and heater 205 form, the electrolysis liquid pump 201, filter 203
It is axially set in 202 upper end of electrolytic bath with cooler 204, the electrolysis liquid pump 201 passes through woven hose 205 and electrolytic bath
202 are connected, and 206 end of woven hose is equipped with fluid hole 207, and the woven hose 206 is equipped with overflow valve 208, the heater
205 are set to inside electrolytic bath 202, and liquid supply pipe 303 is arranged in 302 lower end of the cathode brush head, and 303 end of the liquid supply pipe is set
There is electrolysis nozzle for liquid 304, gear drive 401 and/or flexible shaft transmission mechanism 402, motor are equipped in the machine tool system 4
403, the motor 403 is connected with gear drive 401 and/or flexible shaft transmission mechanism 402, the rotating speed of the motor 403
Selection is in 100 ~ 2000r/min.
The cathode brush head 302 is set as flexible, rigidity Excircle machining rubbing head, interior hole machined rubbing head, keyway processing wiping
Head, narrow slit processing rubbing head, pocket machining rubbing head, type hole processing rubbing head, aperture rubbing head, circular hole rubbing head, square hole rubbing head, porous rubbing head
Structure, the cathode brush head 302 select carbon steel material to be made.
The flexible shaft transmission mechanism 402 includes bearing 402-1, main shaft 402-2 and flexible shaft component 402-3, and the flexible axle passes
402 both ends of motivation structure are equipped with shaft coupling 6.
Electrolyzed Processing power supply 1, power supply under conditions of high current stablize by continuous work, and reliably, accessible, power supply is equipped with quick
The short-circuit protection for direct current output of cutting off the power cuts off electric current so that the signal detection before short circuit occurs comes out, and protection is cloudy
Pole and workpiece, stronger corrosion resistance should ensure that power supply close proximity to processing district to reduce energy consumption, therefore it is relatively strong to require power supply to have
Corrosion resistance, adapt to the working environment of corrosive gas.
The effect of electrolyte system is：In electrochemical machining process, continuously smoothly enough flows are supplied to processing district
With the electrolyte of suitable temperature, continuous purifying electrolysis liquid, harmless treatment is carried out to waste liquid in process.
The electrolysis brush is hand-held, for the electrolytic machine tool of low pressure processing, carries out reaming and polishing, removes flash removed
Processing etc..Therefore select single machine centrifugal pump, feature：
Pressure is low, and output flow range is big；Efficiency is higher, simple in structure, easy to maintenance；Output characteristics is soft, when exporting unsmooth its
Flow can reduce.
Electrolysis brush is small electrolytic process equipment, and flow of electrolyte is small.Therefore case structure is selected, material is stainless steel
Welding manufacture, general steel plate appearance plastic-spraying, liner is anti-corrosion rubber and make.Feature：Floor space is small, easy to make；Electrolyte temperature
The variation of degree and concentration is very fast, and it is more to replace number.
Filter, electrolysis brush use the filter method of media filtration.Work principle of filter is to make electrolyte in the effect of pressure
Down by stainless steel cloth, to which electrolysate be detached.Its feature：Electrolytic efficiency is high, and electrolyte loss is less；Filter is easy
It blocks, the timing phase is cleared up.
Cooling and heating device electrolyte temperature has an impact process velocity, machining accuracy and surface quality.Liquid temperature mistake
Height, electrolyte easily vaporizes when small―gap suture, high current are processed, and so that processing is not normally functioning, and operation employee can be made to be hindered
Evil.And liquid temperature is too low, electrolyte flow is poor, and ohm voltage drop increases, and productivity is made to decline.Therefore, according to external season temperature
Degree and the processing frequency and size of current, using cooling or heating device.
The wiping cuts machine and is suitable for neutral electrolyte.The electrolyte conductivity is relatively low and corrosivity is also small, safe to use, to people
Body is harmless.Anode reflection is to generate the hydroxide of metal, may also generate the gases such as oxygen sometimes, and cathode reaction mainly generates
Hydrogen.It can be recycled after purification, applied widely, type face, cavity, type hole use.NaNO3、NaCl、NaClO3It is common
Three kinds of neutral electrolytes,
Electric machine main shaft is with shaft coupling using being keyed, and flexible axle drive end is used with shaft coupling and is keyed, flexible axle driven end, main shaft master
Moved end uses with shaft coupling and is threadedly coupled.And all be use non-splined sleeve shaft coupling
When electrolysis brush, workpiece connects the anode of DC power supply（Anode）, electrolysis brush head connects the cathode of DC power supply（Cathode）, defeated
Liquid pipe, which connects electrolytic bath fluid hole and wipes, cuts cathode inlet opening, and electrolytic bath certain altitude on workpiece is placed, with facility
Workspace is cut by flowing to cathode in slot and supplying wiping with height official post electrolyte, before formal wiping is cut, first electrolyte is sprayed to and is added
Power supply is restarted in work area domain, holds electrolysis brush cathode opposite piece machined surface and moves back and forth progress " electrolysis brush ", wiping is cut
When, electrolysis brush head contacts working face region and carries out Anodic dissolving to workpiece, cuts head with wiping and does not stop to move, is then electrolysed
Removal region constantly changes, and with movement, and electrolysate is constantly wiped, is clear by electrolysis rubbing head again, repeatedly and more
Change processing district, realize and electrolysis brush is carried out to work pieces process face, therebetween also can intermittently operated, rinsed with electrolyte or special clear
Reason wipes bevel, then cuts result according to wiping and decides whether end operation, still continues, when end or pause are cut in primary wiping,
It is first turned off power supply, then stops electrolyte sprinkling, workpiece is finally cleared up and wipes bevel.
Electrolysis nozzle for liquid and jet pipe can be designed directly to electrolytic bath, workpiece is placed directly in electrolytic bath, is waited for
Processing.This scenario-frame is more simple, operation is more convenient.
The above is the example and explanation of the present invention, but does not mean that the obtainable advantage of the present invention is so limited, all
Being may be to wherein one the advantages of realization in the simple transformation of structure, and/or some embodiments in practice process of the present invention
It is a or it is multiple within the scope of protection of this application.
