<p>The invention deals with a device for position defined clamping of a machined piece within a processing machine. The centering mechanism (1) is equipped with at least two supporting bodies (4, 5) at a certain distance, which feature four centering plugs (23) located in a circle. The bedding (7) of the machined piece features two continuous centering groups (15, 16). The continuous centering group (15) is equipped with four corresponding centering notches (39) assigned to each centering plug, and the other continuous centering group (16) features two centering notches (39a), which are located on a direct line passing the centers of the two centering notch groups (15, 16). This way the position precision corresponding to the bedding (7) of the machined piece can not be adversely affected by the tolerance of the distance between the supporting bodies (4,5) or the centering notch groups (15, 16).</p> |
