Description
Technical field
The present invention relates to a kind of workpiece local surfaces burnishing device, more particularly, to a kind of workpiece based on magnetic rheology effect
Partial high-precision burnishing device.
Background technology
Ultra-Smooth Surface Polishing Techniques are an important components of Ultra-precision Turning system, with research deeply with
And the raising of detection technique, people have more deep understanding to the formation mechenism on nanometer grade super smooth surface, and develop perhaps
More polishing technologies, such as traditional free abrasive polish, and refer mainly to free work circle being dispersed between workpiece and flexible lap tool of abrasive material
In face, active force is applied to abrasive material by workpiece and lap tool, abrasive material is rolled and is slided in working interface, is removed from workpiece
The processing mode of material, this method is in polishing process, the concentration of abrasive material, distributing homogeneity, movement velocity, movement locus and stagnant
Time etc. is stayed not control directly；For another example elastic emission machining, the core component of which is a polishing wheel, polishing wheel and work
A minim gap (about dozens of micron) is kept between part, polishing fluid is full of within the gap.During processing, polishing wheel is high
Speed rotation, makes to form a layer fluid dynamic pressure polished film in minim gap, so as to balance the pressure being applied on polishing wheel.Abrasive material
Faint elastic collision realization occurs with workpiece surface in the presence of hydrodynamic material is removed from workpiece.It is existing based on more than
Shape, compared with tradition polishes, the most significant advantage of MRF is：1st, in polishing process, material removing rate function is all the time
It is constant, this is to polishing so that realizing that numerical control polishing is very favorable.MRF is to utilize to flow in magnetic field
The Magnetorheologicai polishing liquid of change produces what very big shearing force (or pressure) was polished to workpiece to workpiece surface.In polishing process
In, Magnetorheologicai polishing liquid constantly circulates, make " small abrasive nose " that the Magnetorheologicai polishing liquid of generation rheology formed constantly by
Renewal, the problem of abrasion in the absence of bistrique.Therefore, during MRF, material removing rate function is to fix not all the time
Become, it is possible to increase workpiece surface polishes precision；2nd, during MRF, the Magnetorheologicai polishing liquid circulated is continuous
Ground takes away workpiece surface and is polished the chip to get off with heat and workpiece surface caused by " bistrique " friction, and this is very to polishing
Favourable, this can be avoided the generation of the phenomenon that workpiece surface polishing precision reduces caused by thermal stress.The above is excellent
Point makes MRF be favored deeply by people.MRF be especially suitable in, small-bore optical element, particularly workpiece do not advise
Then surface local polishing is processed.Therefore, the present invention polishes for workpiece surface partial high-precision, devises a kind of based on magnetorheological
The workpiece partial high-precision burnishing device of effect, it is desirable to be able to played a role to polishing engineering application field.
Magnetic flow liquid is a kind of magnetorheological intellectual material, and the performance of its rheological behavior is as follows：In the case where being acted on without externally-applied magnetic field, energy
A kind of enough newton body states with stabilization are present, and have preferable mobility, under externally-applied magnetic field effect, internal soft magnetic particles are fast
Speed removes the state that its original is recovered in magnetic field again in magnetic direction chaining column or netted, the process have it is quick, reversible, consume
Can low advantage.Therefore the polishing fluid of the present apparatus use the mass fractions of soft magnetic particles for 81.83% water based magnetic rheologic liquid
(its iron powder diameter is at 2-8 μm) and abrasive material are Al in irregular shape2O3The combination of particle.
The content of the invention
To realize the functional requirement described above for workpiece irregular surface local polishing device, the present invention provides a kind of
Workpiece partial high-precision burnishing device based on magnetic rheology effect.
A kind of present invention workpiece partial high-precision polishing based on magnetic rheology effect a kind of simple in construction and understandable principle
Device is realized as follows：Burnishing device is by motor, shaft coupling, rotating shaft, transparent tank, polishing wheel, permanent magnetic
Iron, moving shaft holder, polishing block, workpiece, polishing fluid, high pressure nozzle, pump, normal force transducer composition.Polishing wheel connects with rotating shaft
Connect, and be suspended at by shaft coupling by motor driven, rotating shaft on moving shaft holder, moving shaft holder is arranged in transparent tank
Portion；Polishing block is placed in transparent tank center, and workpiece is placed on polishing block, and polishing block is internally embedded normal force transducer, polishing wheel
Distance is 2mm between workpiece burnishing surface；Two permanent magnets, two permanent magnet heteropole arrangements are housed, pump is put on polishing wheel
Inside transparent tank end angular zone in opposite direction is polished with workpiece surface；Polishing fluid is ground by water based magnetic rheologic liquid and polishing
Material composition, magnetic flow liquid are the water based magnetic rheologic liquid of the mass fraction 81.83% of iron powder, and for iron powder diameter at 2-8 μm, abrasive material is shape
The irregular Al of shape2O3Particle.
A kind of good effect of workpiece partial high-precision burnishing device based on magnetic rheology effect of the present invention is：
