Description
Technical field
The present invention relates to polishing, especially a kind of constraint abrasive Flow polishing tool head.
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 Ultraprecise polished process technology of hard brittle material part becomes one of active demand and the challenging processing technique field of most.
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.
In recent years, in non-traditional finishing method, micro abrasive water jet polishing due to initial cost low, without fire damage, do not change the mechanics of materials and physical property, polishing characteristic is not by workpiece polishing position influence, be considered to the current hard brittle material goods to having complex surface and carry out one of the most potential method of super smooth surface processing, as shown in Figure 1, nozzle 16 has the distance of a section apart from surface of the work 14, abradant jet bundle 15 with certain speed and angle effect on the surface of the workpiece, because this technology jet beam area of section is little, and nozzle orbit is not limited to rectilinear direction, flat scanning and Machining of Curved Surface can be carried out, therefore be particularly suitable for the Precision Machining of the complex surface of hard brittle material goods, and there is edge effect hardly.At present, also do not form the extensive research of system both at home and abroad, although the advantage of micro-abrasive particle water jet polishing technology is a lot, application prospect is also better, but application is also immature at present, owing to there being a segment distance between nozzle and surface of the work, disperse after causing micro-abrasive particle water jet to leave nozzle, the processing bundle of collimation can not be formed, and then affect the certainty of polishing area, reduce the precision of polishing, and the loose processing mode of abrasive particle causes working (machining) efficiency not high, micro abrasive water jet polishing mainly relies on the high velocity impact shear action of abrasive particle on the other hand, this mechanical shock easily causes workpiece surface damage, moreover due to jet size less, in micro-abradant jet process, very easily block, the material of nozzle needs hard and wear-resisting, cause the manufacture of micro nozzle more difficult.
Summary of the invention
In order to overcome, the existing polishing precision for existing in the polishing of micro-abrasive particle water jet is lower, working (machining) efficiency is lower, there is larger machining damage, deficiency that cost is high, the constraint abrasive Flow polishing tool head that the present invention proposes a kind of polishing precision of workpiece surface and material removing rate is high, machining damage is little, cost is low.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of constraint abrasive Flow polishing tool head, comprise nozzle, sheath, installing plate, rubbing head base and spring, described sheath is sleeved on nozzle, described nozzle is fixedly connected with rubbing head base, described sheath and nozzle mating surface have seal groove, and described nozzle center gets through hole, and described sheath is by the sheath made the insensitive elastomeric material of abrasive wear, be provided with the passage flowed into for abrasive Flow in described rubbing head base, described passage is communicated with described through hole; Described spring housing to be contained on nozzle and to compress sheath, and described rubbing head base is bolted on installing plate, and described installing plate is connected with controlled motion mechanism.
Further, described nozzle and rubbing head base are threaded connection, and described installing plate have rubbing head base installing hole, and described rubbing head base is bolted on installing plate.
Further, described nozzle top is milled with mounting plane, the uniform screwed hole of described rubbing head base surrounding is connected with installing plate by bolt, there is the screwed hole of centre be connected with nozzle at described rubbing head base center, described rubbing head base is provided with gas thread hole from the side and communicates with screwed hole of centre, described gas thread hole is passage, and abrasive Flow feeder sleeve is connected with the gas thread hole on rubbing head.
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, and abrasive Flow flows out from this gap along polishing tool end face, force abrasive particle to carry out polishing to surface of the work.
The present invention changes the generation type of abrasive water-jet completely, by additional constraint, 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.
