A locking mechanism as shown in the figure for the contouring head assembly (108) of a belt grinding machine that employs multiple, parallel, abrasive grinding belts (62, 64; 66, 68; etc.) and back-up shoes (254) for pressing the belts against the surfaces on a workpiece to be ground. The locking mechanism secures the contouring head assembly (108) to the bed of the grinding machine. The locking mechanism includes a protrusion, such as a ball (256) that is carried by the contouring head assembly (108) and a pivotable arm (156) is secured to a shaft (151) that is driven by a rotary actuator, that is powered by a hydraulic motor (150). The socket (266) engages the protrusion (256) to securely support one side of the contouring feed assembly. A hydraulic cylinder (158) forces a tapered plunger (258) against the pivotable arm (156) to enhance the locking action.
L'invention concerne un mécanisme de blocage destiné à un ensemble tête de contournage (108) d'une machine à rubans abrasifs qui utilise des rubans abrasifs parallèles, multiples (62, 64; 66, 68; etc.) et des sabots de retenue (254) serrant les rubans contre les surfaces d'une pièce à rectifier. Le mécanisme de blocage fixe l'ensemble tête de contournage (108) sur la table de la rectifieuse. Le mécanisme de blocage comporte une protubérance, telle qu'une bille (256) supportée par l'ensemble tête de contour (108) et un bras pivotant (156) est fixé à un arbre (151) qui est entraîné par un actionneur rotatif commandé par un moteur hydraulique (150). La cavité d'emboîtement (266) vient en contact avec la protubérance (256) pour soutenir solidement un côté de l'ensemble d'avance de contour. Un cylindre hydraulique (158) pousse un piston plongeur conique (258) contre le bras pivotant (156) afin de renforcer l'action de blocage.
