Abstract

A precise dual-surface polishing machine is composed of machine frame, mainshaft and its drive mechanism, upper polishing disc and its drive unit, lower polishing disc, internal and external toothed rings, planetary gear for holding workpiece, 4 coaxial frequency-conversion motors fro respectively driving coaxial upper and lower polishing discs and external and internal toothed rings, pressure regulating sensors, and pressure regulating valves.

Description

(1) Technical field [0001] The invention relates to the field of polishing machines, in particular to a precision double-sided polishing machine. (2) Background technology [0002] The original traditional polishing machine is driven by a single motor, as shown in Figure 1, through the gear transmission system to realize the rotation of the upper polishing disc 22, the lower polishing disc 23, the inner ring gear 24, and the outer gear ring 25. There are only two types of upper and lower polishing discs and planetary gears. The speed ratio limits the change of the trajectory of the double-sided polishing process, and lacks precise control of the speed. [0003] In order to improve the polishing efficiency, someone has improved the planetary disc of the polishing machine. For example, the Chinese utility model patent No. 02292538.4, whose patent name is the planetary disc of double-sided polishing machine, discloses a double-sided polishing disc. There are 3 eccentric holes,...
