Title (EN) ASSEMBLY FOR RETAINING A CUTTING INSERT IN A POCKET OF A TOOL HOLDER
(FR) ENSEMBLE DE RETENUE DE PLAQUETTE DE COUPE DANS UNE POCHE DE PORTE-OUTIL
Abstract: front page image
(EN)An assembly (16) for retaining a cutting insert (14) in a pocket (12) of a tool holder (10) includes a locking pin (20, 20'), a spring (24) disposed in the bore (28) of the tool holder, a locking plate (22) disposed in the bore between the spring and the locking pin, and a set screw (26) for retaining the assembly. The locking plate (22) is biased against a ledge (28b) of the bore (28) to cause the locking pin (20, 20') to draw and retain the cutting insert (14) in a direction such that the cutting insert is held in a secured position against the pocket (12) of the tool holder (10). To release the cutting insert (14), a force is applied to the assembly (16) to counteract the biasing force of the spring (24). The locking pin 20' or the locking plate (22) may include a flat surface (20f, 22g) that cooperates with a flat surface (28a) on the bore (28) to act as a key to proper orientate the assembly (16) in the bore (28).
(FR)La présente invention concerne un ensemble (16) de retenue de plaquette de coupe (14) dans une poche (12) de porte-outil (10) comprenant une tige de blocage (20, 20'), un ressort (24) disposé dans l'alésage (28) du porte-outil, une plaque de blocage (22) disposée dans l'alésage entre le ressort et la tige de blocage et une vis de calage (26) pour retenir l'ensemble. La plaque de blocage (22) est contrainte contre un rebord (28b) de l'alésage (28) pour faire que la tige de blocage (20, 20') tire sur la plaquette de coupe (14) et la retienne dans une direction telle que la plaquette de coupe soit maintenue en une position sûre contre la poche (12) du porte-outil (10). Pour relâcher la plaquette de coupe (14), une force est appliquée à l'ensemble (16) pour contrecarrer la force de contrainte du ressort (24). La tige de blocage (20') ou la plaque de blocage (22) peut comprendre une surface plate (20f, 22g) coopérant avec une surface plate (28a) sur l'alésage (28) pour jouer un rôle de clavette afin d'orienter l'ensemble (16) dans l'alésage (28).
