Description
Technical field
The utility model relates to a kind of cone spirality abrasive disk, is 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.
Utility model content
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 utility model provides a kind of can integrate the one cone spirality abrasive disk that corase grind, fine grinding, rough polishing, essence are thrown.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of cone spirality abrasive disk, comprise abrasive disk, workpiece feed mechanism and workpiece mounting head, the laminating of workpiece mounting head and abrasive disk, described workpiece mounting head under the drive of workpiece feed mechanism along the card orbiting motion of abrasive disk;
Described abrasive disk disk body is cone spirality, and the abrasive grain in abrasive disk card is along with the helix gradient type of disk body changes, and the closer to the top of cone helix, abrasive grain is higher;
Described abrasive disk disk body is connected with a rotating shaft that is vertically placed on disk body position of center line, and described abrasive disk inwall and rotating shaft are affixed by many straight-bars;
Described workpiece feed mechanism comprises fixed bar, connecting rod, movable block, motor and workpiece mounting head, described workpiece mounting head is contained on motor, described motor is contained in movable block, described movable block is connected by revolute pair with connecting rod, described connecting rod is connected by higher pair with fixed bar, and described higher pair is turned to by three hydraulic cylinder controls.
Further, described workpiece mounting head bottom surface is provided with workpiece installing hole, and workpiece is arranged in workpiece installing hole, and described workpiece installing hole is located at the center of workpiece mounting head.
Further, described workpiece mounting head bottom surface is provided with workpiece installing hole, and workpiece is arranged in workpiece installing hole, and described workpiece installing hole is provided with multiple, is evenly distributed on the bottom surface of workpiece mounting head.
Further, the surrounding of described workpiece mounting head is equipped with roller, and workpiece mounting head is by the sidewall contact of roller and abrasive disk.
Technical conceive of the present utility model is: this programme adopts Cone Disc and connecting rod all can independently rotate, i.e. Cone Disc rotation, and its rotating speed is controlled, and our control link rotates in vertical direction and horizontal direction simultaneously.What mainly consider here is that connecting rod must rotate the matching problem between Cone Disc rotation.(1) Cone Disc rotating speed is controlled, workpiece mounting head starts to move upward from conical base, Cone Disc is made up of multiple parts, extremely, be upwards the processing sections of different accuracy successively, the velocity of rotation of our controlled rounding cone disk-drive motors in each part control the velocity of rotation of Cone Disc in different phase, thereby control milling time.(2) the vertical rotation of control link and horizontally rotating, obtains the movement locus of workpiece mounting head, and the Cone Disc of our design here remains between two inwalls of helical disk workpiece mounting head in the process of motion.(3) because the rotary speed of Cone Disc is not certain, so in the different rotary stage of Cone Disc, accordingly, connecting rod obtains velocity of rotation and also will match with it, thereby the velocity of rotation of connecting rod in the vertical direction will take different velocity of rotation holding workpiece mounting heads not depart from helical disk machined surface according to the different rotary stage of Cone Disc; The speed that horizontally rotates of connecting rod wants holding workpiece mounting head not collide with helical disk two inwalls.(4) due to the motor using, the self gravitation of motor is as the force mechanism of workpiece.(5) turn to because higher pair is subject to three hydraulic cylinder controls, by control three hydraulic cylinder different times situation make different motions, realize freely rotating of connecting rod.
Compared with prior art, the utlity model has following advantage: the utility model is simple and compact for structure, cost is lower, and automaticity is high, by controlling the abrasive grain of abrasive disk different piece, can carry out respectively the thick processing of precision in various degree to workpiece; When abrasive disk rotates, workpiece mounting head also can rotation under the drive of motor, 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.
