Description
Technical field
The present invention relates to a kind of change granularity spirality mill, be applicable to the lapping and polishing processing of the surface of the work such as optical element, noncrystal membrane substrate.
Background technology
Grinding utilizes coating or presses the abrasive grain be embedded on lap tool, the finished machined (as machining) of being carried out finished surface by lap tool and workpiece relative motion under a certain pressure.Grinding can be used for processing various metal and nonmetallic materials, and the surface configuration of processing has plane, the inside and outside face of cylinder and taper seat, convex, 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.Utilize the modification processing that flexible polishing instrument and abrasive grain or other polishing mediums carry out surface of the work.Polishing can not improve dimensional accuracy or the geometrical precision of workpiece, but to obtain for the purpose of smooth surface or bright luster, sometimes also in order to eliminate gloss (delustring).
When we need to carry out skin processing to for processing work, in order to improve workpiece surface roughness or to strengthen the process on its surface, usually adopt grinding and polishing simultaneously.Traditional utilizes the polishing system of abrasive disk or polishing disk by lapping and polishing operation separately, makes to be needed abrasive disk to be replaced by polishing disk to system during polishing by overgrinding, 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 completely or need process time of growing very much.And traditional grinding and polishing system, add the pressure that man-hour requirement is artificially added counterweight or decided to put 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 can not obtain dynamic adjustments according to process requirements and cannot obtain the pressure of gravity of the device lower than workpiece and support workpiece itself, need add or change counterweight after replacing abrasive disk or polishing disk, because the quality of counterweight is fixed, stressed consecutive variations is executed in very difficult realization, thus have impact on crudy, and be affected by human factors large, be difficult to realize automation.
Summary of the invention
In order to overcome, the working (machining) efficiency existed in prior art processing is low, automaticity is not high, polishing and attrition process need the shortcoming such as separately, the invention provides a kind of one change granularity spirality mill that can integrate corase grind, fine grinding, rough polishing, essence throwing.
For achieving the above object, the technical solution adopted in the present invention is: a kind of change granularity spirality mill, and comprise abrasive disk and workpiece feed mechanism, abrasive disk is equipped with spiral baffle on the surface, and the surperficial granularity of abrasive disk is along with the change of spiral baffle gradient type; Abrasive disk is fixed on base, and base is built with driving the drive motors of abrasive disk, the affixed rotating seat of base side, and rotating seat is provided with turning arm, and described turning arm connects workpiece feed mechanism; Workpiece feed mechanism comprises trade union college head, supporting seat, cylinder, workpiece motor, rotating shaft and workpiece motor fixing plate, supporting seat is equipped with cylinder, the piston rod of cylinder is by the affixed workpiece motor fixing plate of nut, fixation workpiece motor on workpiece motor fixing plate, the rotating shaft that workpiece motor is placed by shaft coupling vertical connecting; Supporting seat is provided with axis hole straight down, and rotating shaft is connected by taper roll bearing with supporting seat, connects trade union college head bottom rotating shaft; Workpiece motor fixing plate horizontal positioned is also provided with two guiding rod aperture straight down, and be each passed through a guide post in each guiding rod aperture, the bottom of two guide posts is fixed on supporting seat; The system of workpiece motor, decelerator, rotating shaft, trade union college head, workpiece motor fixing plate composition moves up and down under the effect of cylinder.
Further, the surperficial granularity of abrasive disk changes along with spiral baffle, and the closer to spirality center, the surperficial granularity of abrasive disk is higher.
Technical conceive of the present invention is: utilize spirality abrasive disk to carry out Continuous maching to workpiece, the surperficial granularity of abrasive disk changes along with spiral baffle, the closer to spirality center, the surperficial granularity of abrasive disk is higher, workpiece adds man-hour on abrasive disk, because abrasive grain constantly changes, simultaneous grinding linear velocity along with slower the closer to abrasive disk center, thus realizes the attrition process of different accuracy; Abrasive disk is provided with spiral baffle, and when can prevent from processing, abrasive dust splashes to adjacent region; The base side of abrasive disk is equipped with rotating seat, and the turning arm on rotating seat can drive workpiece feed mechanism freely to rotate centered by rotating seat.
Trade union college head contacts with the baffle plate on abrasive disk after entering abrasive disk.During work, under the driving of drive motors, abrasive disk rotates, and now can give first radial load of trade union college by baffle plate, thus drive whole workpiece feed system to rotate around rotating seat, realize trade union college head from spirality abrasive disk outer ring to the motion of inner ring; Trade union college head rotation under the driving of motor simultaneously realizes the processing texture disordering of work surface.
Pressure required when the gravity of system itself of trade union college head, rotating shaft, shaft coupling, workpiece motor, workpiece motor fixing plate composition enough provides workpiece to grind, therefore provides extra pressure without the need to counterweight again.Said system moves up and down under the effect of cylinder block, thus realize trade union college head enter abrasive disk with leave abrasive disk.
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 functionally graded design of spirality abrasive disk, the processing in various degree of the throwing from corase grind to essence can be carried out respectively to workpiece; Time grinding and polishing dish rotates, workpiece also can follow spinning motion, can realize the processing texture disordering of work surface thus improve working (machining) efficiency and quality under the acting in conjunction of the two.
