Patent

CA 2422939

The invention relates to a chip removing tool comprising a tool shank (1) which acts as a support for a perforated plate (3). The perforated plate (3) is tensed by means of a screw connection passing through the orifice (19) of the perforated plate (3) and a through hole (22) of the tool shank (1), containing a screw (17) which is introduced from the side of the perforated plate, and a corresponding nut (18) positioned beneath the tool shank (1) inside the seat (4) of the tool shank (1). The tensed perforated plate (3) is adjusted in an effective manner in a direction of adjustment (3) which is substantially radial in relation to the axis of rotation (8) of the tool shank (1), whereby the contact surfaces between a) the screw head (23) and the perforated plate (3) and b) the head (24) of the corresponding nut (18) and the tool shank (1) enable a pivotable movement of the screw connection following on from the adjustment movement, said screw connection consisting of a screw (17) and a corresponding nut (18), as a result of crowning.

La présente invention concerne un outil d'enlèvement de copeaux, qui comprend une tige d'outil (1) servant de support à une plaque perforée (3). Cette plaque perforée (3) est contrainte à l'intérieur d'un logement de plaque (4) de la tige d'outil (1), par l'intermédiaire d'un système de connexion par vis, qui passe à travers l'orifice (19) de la plaque perforée (3) et à travers un orifice de passage (22) de la tige d'outil (1) et qui comprend une vis (17), introduite du côté de la plaque perforée, ainsi qu'un écrou correspondant (18), placé en dessous de la tige d'outil (1). Les surfaces de contact entre la tête de la vis (23) et la plaque perforée (3) d'un côté et entre la tête (24) de l'écrou correspondant (18) et la tige d'outil (1) d'un autre côté permettent par bombement au système de connexion par vis, constitué de la vis (17) et de l'écrou correspondant (18), de pouvoir effectuer un mouvement de pivotement suivant le mouvement de réglage, ce qui favorise un réglage efficace de la plaque perforée contrainte (3) dans la direction de réglage (9), de manière sensiblement radiale à l'axe de rotation (8) de la tige d'outil (1).
