Abstract

L'invention concerne une machine de meulage et de polissage comprenant un corps, un mécanisme rotatif excentrique, un mécanisme à mouvement linéaire à va-et-vient et un accessoire (9). Le mécanisme rotatif excentrique est constitué principalement d'une manivelle (2). La manivelle (2) est formée par raccordement d'un arbre rotatif (5) avec deux à dix segments d'arbres excentriques (4). L'arbre rotatif (5) est supporté dans le corps par des paliers. Chaque arbre excentrique est disposé de manière excentrique et parallèle par rapport à l'arbre rotatif (5). Le mécanisme à mouvement linéaire à va-et-vient est constitué d'arbres principaux (1) et de liaisons (3), et le nombre des arbres principaux et des liaisons est identique au nombre des arbres excentriques (4). Chaque liaison est raccordée entre l'un des arbres principaux (1) et un segment des arbres excentriques (4). Une extrémité de la liaison (3) est raccordée par une charnière à l'arbre excentrique (4), et l'autre extrémité est raccordée par charnière à l'arbre principal (1). Chaque arbre principal (1) est disposé de manière parallèle et est supporté par une paire coulissante axiale. Cette invention est compacte dans sa structure et commode à utiliser. Il est possible d'améliorer l'efficacité de polissage et de diminuer le temps de polissage de la machine.
