Be: including workbench, workbench side is equipped with control panel, and workbench is equipped with polishing trough, is equipped with lower millstone in polishing trough,
Lower millstone is connected with the motor being arranged in below workbench；Bias is placed with circular plate retainer on the lower millstone；It is described
It is in the equally distributed cylindrical hole of concentric circles that circular plate retainer, which is equipped with one group, and the diameter of cylindrical hole compares circular slab
The thickness of part retainer is big；It is corresponding, pressurizing device is eccentrically provided with above the lower millstone；The pressurizing device includes being set to
Pressurization rack on workbench, pressurization rack are equipped with cylinder, the fixed connection in the lower end of the piston rod of cylinder and the upper end of extension bar
It connects, the lower end of extension bar is coupled by thrust bearing with upper millstone；It is arranged on lower surface and is uniform-distribution with outside the upper millstone
The finishing ring of radial rectangular channel, the height of the rectangular channel are less than the thickness of the circular plate retainer.
Compared with prior art, the equipment of the utility model is in polishing, since finishing ring limits circular plate retainer
Production is used, and in the case where the revolving speed centrifugal force for improving lower millstone becomes larger, circular retainer can still do dead axle rotation, no
Material removing rate guarantees that revolution does not upset the track of rotation again when improving only polishing；Sphere is kept in lower millstone, circular plate
Under the synergistic effect of frame and upper millstone, there is specific motion profile, can be realized the full envelope of machining locus, to realize material
The uniform removal of material, the product surface of acquisition is highly polished and batch consistency is good.
As optimization, the working shaft of the motor is equipped with motor shock absorption device.Ailevator produces on vertical direction at work
Raw vibration improves machining accuracy.
As optimization, 120 degree of spacing annular in shape are stained with 3 circular pads on the downside surface of the circular plate retainer
Piece.Studies have shown that circular gasket can not only reduce the abrasion of the circular plate retainer, the good of polishing fluid is additionally aided
Circulation, to improve polishing efficiency.
As optimization, the material of the circular plate retainer is polymethyl methacrylate.Polymethyl methacrylate
Hardness it is smaller, when for processing the sphere bigger than its hardness, sphere is not easy to cause to deform because of extruding.
As optimization, the bottom of the polishing trough is equipped with leakage fluid dram.For waste and old polishing fluid to be discharged, facilitate polishing trough
Cleaning.
