Title:
LAPPING AND POLISHING MACHINE AND AUXILIARY MECHANISM THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/041391
Kind Code:
A1
Abstract:
A lapping and polishing machine and an auxiliary mechanism thereof. The auxiliary mechanism comprises an indexing plate (10), a bushing (20), and an eccentric assembly (30). One end of the bushing (20) is provided with a rotating shaft (210), and the other end is provided with a first shaft hole (220). The center of the first shaft hole (220) is not coaxial with the center of the rotating shaft (210). The rotating shaft (210) is rotatably connected to the indexing plate (10). One end of the eccentric assembly (30) is provided with a position-limiting column (310), and the other end is connected to a polishing wheel. An arc-shaped hole (230) is provided on an end surface of the bushing (20) near the indexing plate (10). The indexing plate (10) is provided with an adjustment hole (110). The eccentric assembly (30) is provided in the first shaft hole (220), and the position-limiting column (310) sequentially passes through the arc-shaped hole (230) and the adjustment hole (110). Multiple positioning holes (120) are provided on the indexing plate (10). The bushing (20) engages with one of the positioning holes (120) by means of a position-limiting mechanism (40), so as to be retained on the indexing plate (10). An eccentric distance between the eccentric assembly (30) and the rotating shaft (210) can be changed to adjust the radius of curvature of the rotation of the polishing wheel, thereby changing a motion trajectory of the polishing wheel to achieve different polishing effects.
