Title:
LAPPING AND POLISHING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2019/041393
Kind Code:
A1
Abstract:
A lapping and polishing mechanism comprises an indexing plate (10), a bushing (20), an eccentric sleeve (330), an eccentric adjustment piece (320), a spring (340), a position-limiting column (310), and a connecting shaft (360). The eccentric sleeve (330), the eccentric adjustment piece (320), and the spring (340) are all provided in a first shaft hole (220) of the bushing (20). A bearing (370) and a clutch adjustment block (350) are provided in a second shaft hole (336) of the eccentric sleeve (330), wherein the clutch adjustment block (350) engages with the eccentric adjustment piece (320). One end of the spring (340) abuts the bushing (20), and the other end abuts the eccentric adjustment piece (320). The eccentric adjustment piece (320) is provided with a through hole (321). The connecting shaft (360) passes through the bearing (370), the clutch adjustment block (350), and the eccentric adjustment piece (320). The clutch adjustment block (350) is fixedly connected to the connecting shaft (360). The bearing (370) and the eccentric adjustment piece (320) are rotatably connected to the connecting shaft (360). One end of the position-limiting column (310) is provided on the eccentric sleeve (330), and the other end sequentially passes through the through hole (321), an arc-shaped hole (230), and an adjustment hole (110). The invention can adjust the radius of curvature of the rotation of the polishing wheel, and prevent excessive force exerted on the polishing wheel during polishing from causing a deep scratch on a polished surface, thereby improving polishing effects, and eliminating polishing defects.
