Miniaturized high-precision double-sided polishing machine

Abstract

The application provides a small-sized high-precision double-sided polishing machine, which comprises an upper and lower outer tooth driving assembly for driving rotation of upper and lower disc main driving gears, an inner tooth driving assembly for driving rotation of an inner ring main driving gear, an inner and outer ring lifting assembly for driving upward and downward movement of the inner ring and the outer ring, a lower disc assembly comprising an auxiliary shaft, which is provided with an upper disc, a lower disc and an outer ring gear set for driving rotation of an upper disc shaft, a lower disc shaft and an outer ring seat respectively, and an upper disc assembly.The application synchronously drives the upper grinding disc, the lower grinding disc and the outer ring through the upper and lower outer tooth driving assembly, the speed ratio is fixed and unchanged, the revolution and rotation are uniform and stable, the grinding track is fully covered, there is no dead angle and repetition, the grinding is more uniform, the workpiece front and back surfaces are synchronously and equally ground, the thickness difference is extremely small, the batch precision is highly unified, one set of power simultaneously drives the upper grinding disc, the lower grinding disc and the outer ring, the synchronous response is fast, there is no multi-motor asynchronous error, and the control is simpler and more stable.
