Abstract

Un support de retenue de disque peut être aisément retenu sur un dispositif de retenue de disque d'une seule pression. De plus, il est possible d'empêcher un disque retenu par le support de retenue de disque d'être secoué par de fortes vibrations agissant sur la meuleuse pendant une opération de meulage de marbre. Par conséquent, une opération de meulage précise et sûre peut être effectuée. Le support de retenue de disque ne peut pas être détaché du dispositif de retenue de disque car, si le disque est coincé dans une pièce de coupe, celui-ci ne peut pas maintenir la position par une force de rappel d'un ressort. Le dispositif de retenue de disque est simplifié pour avoir une structure mince de sorte qu'un disque disponible dans le commerce peut être utilisé de manière interchangeable avec la meuleuse. Selon la présente invention, le dispositif de retenue de disque de meuleuse présente une configuration simple de sorte qu'il peut être fabriqué de manière simplifiée. La structure d'assemblage est réalisée par étapes, ce qui permet d'obtenir une facilité d'assemblage. L'arbre rotatif de la meuleuse fixé à l'élément de fixation rotatif du dispositif de retenue de disque est exposé à la partie supérieure du dispositif de retenue de disque de sorte que non seulement un disque dédié, mais également un disque universel peuvent être utilisés de manière interchangeable. Le disque peut être retenu aisément d'une seule pression. De plus, il est possible d'empêcher le disque de meulage d'être secoué par des vibrations fortes agissant sur la meuleuse pendant une opération de meulage de marbre, par exemple. Par conséquent, la surface de la cible de traitement peut être meulée et coupée avec précision. Ainsi, l'équilibre de rotation peut être amélioré, ce qui permet d'augmenter la durée de vie et d'améliorer les performances de coupe, et de pouvoir procéder à une opération précise en toute sécurité.
