Description
Technical field
The present invention relates to a kind of plane polishing device, be applicable to grinding and the polishing of the surface of the work such as optical element, noncrystal membrane substrate.
Background technology
Grinding is to utilize coating or press the abrasive grain being embedded on lap tool, the finished machined (as machining) that the relative motion under certain pressure is carried out finished surface by lap tool and workpiece.Grinding can be used for processing various metals and nonmetallic materials, and the surface configuration of processing has plane, the inside and outside face of cylinder and taper seat, protruding, concave spherical surface, screw thread, the flank of tooth and other profiles.Machining accuracy can reach IT5～01, and surface roughness can reach Ra0.63～0.01 micron.
Polishing refers to and utilizes machinery, chemistry or electrochemical effect, workpiece surface roughness is reduced, to obtain the processing method of light, flat surface.The modification processing that utilizes flexible polishing instrument and abrasive grain or other polishing mediums to carry out surface of the work.Polishing can not improve dimensional accuracy or the geometrical precision of workpiece, but to obtain smooth surface or bright luster as object, sometimes also in order to eliminate gloss (delustring).
When we need to, to carrying out polishing processing for processing work, in order to improve workpiece surface roughness or to strengthen its surperficial process, adopt and grind and polishing conventionally simultaneously.Traditional polishing system of utilizing abrasive disk or polishing disk is separated grinding and polishing process, and while making by overgrinding to polishing, system need to be replaced by polishing disk by abrasive disk, is difficult to promote working (machining) efficiency.Even single attrition process, the abrasive disk of single wear particle size also can not make workpiece reach required surface roughness or process time that need to be very long completely.And traditional grinding and polishing system, adding man-hour requirement artificially adds counterweight or is decided the pressure that puts on surface of the work and abrasive disk (or polishing disk) surface by the gravity of the device of workpiece and support workpiece itself, this makes be applied pressure not obtain dynamic adjustments and cannot obtain the pressure lower than the gravity of the device of workpiece and support workpiece itself according to process requirements, after replacing abrasive disk or polishing disk, need to add or change counterweight, because the quality of counterweight is fixed, the continuous variation that very difficult realization is exerted pressure, thereby affect crudy, and be affected by human factors large, be difficult to realize automation.
Summary of the invention
The shortcomings such as the working (machining) efficiency existing in prior art processing is low, automaticity is not high in order to overcome, polishing and attrition process need to be separated, the invention provides and a kind ofly can integrate a kind of plane polishing device that corase grind, fine grinding, rough polishing, essence are thrown.
For achieving the above object, the technical solution adopted in the present invention is: a kind of plane polishing device, comprise emery wheel, slide unit and workpiece movable mechanism, and described emery wheel is square, the card granularity of described emery wheel extremely increases progressively again from a left side successively along long side direction; Described emery wheel is contained on slide unit, roller screw and line slideway are equipped with in described slide unit below, described roller screw and line slideway horizontal parallel are placed, and motor is equipped with in one end of described roller screw, and described slide unit moves horizontally under the effect of roller screw and line slideway;
Described workpiece movable mechanism comprises portal frame, and described portal frame is fixed on emery wheel top, on described portal frame, cam link mechanism is housed;
Described cam link mechanism comprises cam, first connecting rod, second connecting rod, third connecting rod, the connected mode of described cam and first connecting rod is for being movably hinged, described first connecting rod and second connecting rod are movably hinged, described second connecting rod is vertical with third connecting rod affixed, and described second connecting rod is connected by fixed hinge with the platform that stretches out being arranged on portal frame with the link position of third connecting rod;
The tache motorice of described third connecting rod connects workpiece installation shaft, and the bottom of described workpiece installation shaft connects vacuum cup.
Technical conceive of the present invention is: abrasive disk is designed to square, square emery wheel is more and more higher along long side direction abrasive grain, when workpiece is after grind along short side direction a position, fine gtinding is again carried out in the region that can directly enter higher abrasive grain, thereby realizes the object of stepless processing.
Workpiece of the present invention does among a small circle half circular motion under the effect of cam link mechanism, square emery wheel can move horizontally under the effect of line slideway and roller screw, both relative motions have caused that the relative motion engineering of workpiece and square abrasive disk has formed the disordered motion of workpiece and direction abrasive disk, thereby have improved machining accuracy.
Compared with prior art, the present invention has the following advantages: the present invention is simple and compact for structure, and cost is lower, and automaticity is high, by the abrasive grain gradient distribution design of square abrasive disk, can carry out respectively the processing in various degree of throwing from corase grind to essence to workpiece; When grinding and polishing dish moves horizontally, workpiece can carry out half circular motion under the drive of cam link mechanism, thereby the processing texture disordering that can realize work surface under the acting in conjunction of the two has improved working (machining) efficiency and quality.
