Abstract
The invention discloses a kind of accurate outer rotor air bearing burnishing device, the polishing barrel that the present invention rotates is located at the outside of air-bearing, and polishing barrel is inside and outside to be contacted with air, considerably increases radiating efficiency, therefore do not need that radiator structure specially is arranged;Transverse bearing uses orifice restriction, and axial bearing uses Porous, and guarantee air-floating main shaft so radially has bigger bearing capacity in grinding, axial to have relatively high rigidity.
Description
Technical field
The invention belongs to automate components range, in particular to a kind of ultraprecise outer rotor air bearing burnishing device structure.
Background technique
Existing sanding and polishing device is usually that a column sanding block rotation is fixedly connected with by a rotation axis, thus real
Now to the polishing of workpiece, but this polishing form, it can only be dropped by accelerating the flowing of gas or liquid outside sanding block
Temperature, cool down low efficiency, can not effectively contain the promotion of polishing deblocking temperature, and sanding block and workpiece can gradually go out under high-temperature condition
Phenomena such as softening transform that existing hardness reduces, influence the final quality of finish of workpiece.
Summary of the invention
The object of the present invention is to provide a kind of accurate outer rotor air bearing burnishing device, the polishing barrel that the present invention rotates is located at gas
The outside that floating axle is held, polishing barrel is inside and outside to be contacted with air, considerably increases radiating efficiency, therefore does not need specially to set
Set radiator structure;Transverse bearing uses orifice restriction, and axial bearing uses Porous, in this way guarantee air-floating main shaft diameter in grinding
To with bigger bearing capacity, axially there is relatively high rigidity.
To achieve the above object, technical scheme is as follows:
A kind of precision outer rotor air bearing burnishing device, including motor stator, motor stator are arranged with polishing barrel outside;The master
Transverse bearing is installed between axis stator and polishing barrel, if being formed with dry bearing throttle orifice on transverse bearing;On motor stator also
Thrust bearing there are two being arranged;Two thrust bearings are respectively at transverse bearing both ends;Spindle end is installed on the outside of thrust bearing
Lid, main shaft end cap are fixedly connected with polishing barrel;The motor stator internal shaping has transverse bearing gas circuit and thrust bearing gas circuit;Diameter
It is connected to bearing gas circuit with bearing throttle orifice;Axial stomata is formed on thrust bearing, thrust bearing gas circuit and axial stomata connect
It is logical;8 both ends of polishing barrel are arranged with transmission belt 11, and transmission belt 11 is solid to be connected with the shaft of rotating device 12.
Further to improve, the main shaft end cap is fixed by lock-screw and polishing barrel.
Further to improve, the thrust bearing is made of porous material ceramics or graphite;The inner ring of thrust bearing
It crosses win cooperation to be fixed on motor stator, outer ring is separated with polishing barrel air film.
Further to improve, the rotating device is motor or rotary cylinder.
Detailed description of the invention
Fig. 1 is structure chart of the invention.
Specific embodiment
The invention by transverse bearing gas circuit 1, thrust bearing gas circuit 2, lock-screw 3, main shaft end cap 4, thrust bearing 5,
Transverse bearing 6, bearing throttle orifice 7, polishing barrel 8, motor stator 9, axial stomata 10, transmission belt 11, rotating device 12 etc. are several
Part forms.
Transverse bearing gas circuit 1 passes to the throttling of transverse bearing by the stomata guidance air-flow opened up inside motor stator
Hole, which provides, stablizes air pressure.
Thrust bearing gas circuit 2 passes to the axial stomata 10 of transverse bearing and thrust bearing by motor stator surface pores
Thrust bearing, which provides, stablizes air pressure, forms gas mould in thrust bearing two sides.
Lock-screw 3, main function are that main shaft end cap and polishing barrel are fixedly connected with rotation.
Main shaft end cap 4, rotates together with polishing barrel, forms air film between thrust bearing and separates;
Thrust bearing 5, using porous material ceramics or graphite, inner ring is crossed win cooperation and is fixed on motor stator, outside
Circle is separated with polishing barrel air film.
Transverse bearing 6, using orifice restriction principle, the regularly arranged throttle orifice on bearing, can be used brass or copper class is closed
Gold is used as making material, and transverse bearing inner ring is solid and motor stator tight fit, outer ring and polishing barrel formation have steady pressure
Air film.
Throttle orifice 7 forms stable air pressure using orifice restriction principle.
The motor stator 9 plays a part of determining main spindle's.
Polishing barrel 8 is external to contact with air for polishing to article, forms gas between internal and motor stator 9
Film progress is thermally conductive, thus it is thermally conductive to the inside and outside carry out of polishing barrel simultaneously, increase its heat transfer efficiency, it is therefore prevented that due to temperature when polishing
Grinding efficiency decline and temperature is excessively high damages caused by workpiece caused by degree improves.The transmission belt that polishing barrel 8 passes through two sides
Rotation is driven, ensure that the dynamic equilibrium during that of its turn.
Specific embodiment should compare Summary and be understood, to avoid unnecessary misunderstanding.In addition, this example
The content is merely used to help understand method and its core concept of the invention.It should be pointed out that for the skill of the art
, without departing from the principle of the present invention, can be with several improvements and modifications are made to the present invention for art personnel, these change
It is also fallen within the protection scope of the claims of the present invention into modification.
