Description
Technical field
The utility model relates to a kind of idler frame of centrifugal roll mill polishing machine.
Background technology
Existing centrifugal roll mill polishing machine is all to adopt simple planetary body, and electric machine rotation is resolved into the cylinder that loads polish parts was both revolved round the sun, and does again reverse rotation, grinds and realizes polishing object thereby polished part and abrasive material mill liquid are produced mutually.Cylinder axis and rotation axis coincide, and rotation and revolution switched in opposite make in cylinder workpiece and abrasive particle abrasive material make two dimension mandatory mobile, and under centrifugal pressure effect, produce the effects such as extruding, friction, collision and realize the polishing attrition process of surface of the work.Owing to being the abrasive action of two-dimensional directional, only have radially and circumferential grinding, not axially rubbing action relatively, thus the abrasive action that workpiece is subject to a little less than, efficiency is lower, process time is longer, and polishing effect is not good.
In prior art, also there is a kind of cylinder being arranged on eccentric stiffener.It makes cylinder rotation, due to eccentric stiffener, therefore cylinder barrel in rotation process gives the bearing reaction of workpiece and abrasive particle abrasive material and axially has an angle, thereby produce an axial thrust load, under the effect of this axial thrust load, workpiece will produce axial forced flow, in conjunction with radially with circumferential forced flow, cylinder in a material will make spiral helicine tumbling motion.This is the two dimensional motion of another kind of form.
If above-mentioned two kinds of two dimensional motions are combined, can realize three-dimensional motion, this grinding for material is also more favourable.But eccentric stiffener is generally all realized based on bent axle, cam structure or eccentric wheel structure.But such structure generally all needs larger volume, has larger quality, once there is eccentric rotary, just bring serious unstability to system.
