Description
Technical field
The present invention relates to polishing processing device.
Background technology
The hard brittle materials such as optical glass, optical crystal, engineering ceramics have that hardness is high, the optical property of wearability and the very good mechanical properties such as corrosion stability is good and uniqueness, its machining accuracy and surface quality requirements are also more and more stricter, and the Ultraprecision Machining of hard brittle material part becomes one of active demand and the challenging processing technique field of most.
There is open defect in traditional mechanical polishing method, be difficult to the processing request meeting the low damage optical surface of high accuracy ultra-smooth, be no longer applicable to the Ultra-precision Turning of this type of optical element in the controlled removal of material, surface damage and working (machining) efficiency etc.
The polishing how realizing high accuracy high quality and high efficiency is hard brittle material Ultra-precision Turning urgent problem.Adopt computer-controlled deterministic theory (CCOS) technology, by the removal function determined, carry out the controlled polishing of pointwise, can obtain the high-quality finished surface of high accuracy, the advanced polishing technology developed on this basis such as computer controls the developing direction that small abrasive nose polishing, ion beam polishing, air bag polishing, abradant jet polishing, MRF and Magnetorheological Jet Polishing etc. represent Ultraprecise polished technology.
But air bag polishing clearance is limited, be difficult to remove for the high-frequency information existed in workpiece, this is also ubiquitous phenomenon in computer control optical surface formation technology.Ion beam polishing etc. can obtain high surface roughness, but material removing rate is extremely low, usually only for after the glossings such as CMP, reduce workpiece surface damage layer further, improve surface quality, and processing cost are high.MRF, while effectively removing low frequency face shape error, easily produces medium-high frequency error, thus worsens the image quality of optical system, particularly remarkable for light laser height energy-gathering system high-resolution detection system.On the other hand, magnetorheological device is complicated, and need to configure different magnetic flow liquids for different workpiece materials, processing cost is higher.Because abrasive flows is without constraint, causing micro-abradant jet to be dispersed to surface of the work, is not the boundling determined, causes the machining accuracy of micro-abradant jet on the low side.In addition, the mechanical shock of micro-abrasive jet to surface of the work easily causes machining damage, can not meet the actual needs of low damage optical element polishing.Magnetorheological Jet Polishing technology reduces the angle of divergence of abrasive Flow, in the certainty of the complicated surface such as concave optical part and inner chamber of high steepness is precise polished, have potential unique advantage.But Magnetorheological Jet Polishing needs special magnetic flow liquid, the same with MRF, and processing cost is higher.
Summary of the invention
The present invention is directed to the polishing problem of existing hard brittle material part, the present invention proposes the constraint abrasive Flow polishing processing device of a kind of polishing precision and material removing rate is high, the machining damage of workpiece surface is little, cost is low hard brittle material complex curved surface parts.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of constraint abrasive Flow polishing processing device of hard brittle material complex curved surface parts, described processing unit (plant) comprises polishing tool head, spring, holding screw, holder, reclaim base and polishing robot, described polishing tool head is the tool heads made the insensitive elastomeric material of abrasive wear, described holding screw is sleeved in holder centre bore, described spring housing is contained in outside holding screw, the described holding screw other end is connected with polishing tool head and holddown spring, described workpiece is fixed on and reclaims on base, described holder and polishing machine robot end are fixed, counterbore is had above described holder centre bore, space is had between described holding screw top and polishing machine robot end, described polishing tool head is column type, there is screwed hole at center, described polishing tool head upper surface, described polishing tool head is beaten blind hole and is formed abrasive Flow cavity volume from lower surface, there is abrasive material charging hole described polishing tool head side, described abrasive material charging hole communicates with abrasive Flow cavity volume, described recovery base center is the boss installing workpiece, and described boss surrounding has abrasive Flow accumulator tank, is with a circle abrasive Flow baffle plate outside described accumulator tank, and described abrasive Flow baffle plate, higher than workpiece surface, has abrasive Flow to reclaim outlet in described accumulator tank.
Further, described abrasive Flow is reclaimed outlet and is connected with the charging aperture of recovery pump by pipeline, the discharging opening of described recovery pump and the charging aperture of agitating device are connected, the discharging opening of described agitating device is connected with the charging aperture of charging pump, the discharge opening of described charging pump and the abrasive material charging hole of polishing tool head upper surface are connected, described Pressure gauge is arranged between the connection tracheae of agitating device and feeding device, and described charging pump and recovery pump have flow regulator.
Technical conceive of the present invention is: polishing tool head passes through the adjustable elastic pressure of spring pre-add one, and when polishing tool does not have the pressure of abrasive Flow or abrasive Flow large not in front, polishing tool lower surface is crushed on surface of the work; Once the abrasive Flow pressure in polishing tool is greater than additional elastic pressure, polishing tool lower surface and surface of the work form a gap, abrasive Flow flows out from this gap along polishing tool end face, abrasive particle is forced to carry out polishing to surface of the work, adopt the path of polishing robot planning Machining of Curved Surface, realize the automation polishing of hard brittle material part curved surface.
Abrasive Flow is under the constraint of polishing tool, change the generation type of abrasive water-jet completely, need not can realize jet processing by minimum superfine nozzle, during machining state, rubbing head presses to surface of the work, abrasive flows is under the constraint of polishing tool head, change jet direction, flowed out along the tangential high speed with surface of the work by polishing tool end surface.When application the method carries out polishing, the processing mode that loose abrasive Flow normal direction is sprayed is changed into the tangential abrasive Flow Machining mode obligated, not only solve the instability problem at jet beam interface, and abrasive particle is moved along surface of the work, enhance the shear action of abrasive particle to surface of the work, weaken the normal direction percussion of abrasive particle to surface of the work, mainly surface of the work material is removed in the shearing of abrasive Flow and scratching effect.Therefore, the method both can reduce impact injury, had again stronger material removal ability.
Abrasive Flow can be recovered by accumulator tank and recycle, and has saved processing cost, has decreased environmental pollution.
Beneficial effect of the present invention is: polishing precision and material removing rate high, the machining damage of workpiece surface is little, cost is low.
