Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] Referring to Fig. 2 and Fig. 3, a main shaft transmission mechanism of a precision double-sided polishing machine includes a frame 1, four frequency conversion motors, a long shaft 6 for driving the upper polishing disc to rotate, a small shaft 7 for driving the inner ring gear to rotate, and a drive The middle shaft 8 that rotates the lower polishing disc and the large shaft 9 that drives the outer ring gear to rotate, the output shaft of the first variable frequency motor 2 is connected to the first transmission belt 10 to drive the long shaft 6, and the bottom end of the long shaft 6 is connected to the long shaft bearing 11. The long shaft bearing 11 is installed on the frame 1; the output shaft of the second frequency conversion motor 3 is connected with the second transmission belt 12 to drive the small shaft 7, and the bottom end of the small shaft 7 is co...

Abstract

A mainshaft drive mechanism of precise dual-surface polishing machine is composed of machine frame, 4 coaxial frequency-conversion motors, and the coaxial long axle for upper polishing disc, small axle for internal toothed ring, medium axle for lower polishing disc and big axle for external toothed ring, which are respectively driven by said 4 frequency-conversion motors.

Description

(1) Technical field [0001] The invention relates to the field of polishing machines, in particular to a spindle transmission mechanism of 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...
