WEDGE-LEVER MECHANISM OF A HYDRAULIC SELF-CENTERING CLAMPING DEVICE

Workpiece 1 is located and clamped by two V-blocks 2 which slide in fixed slots. When piston 3 is moved upward by the action of fluid delivered to the bottom end of the cylinder, conical member 4, mounted rigidly on the piston rod, spreads plungers 5 an equal distance from the centre. Plungers 5 turn levers 6 about fixed axes A. This pushes V-blocks 2 inward to clamp workpiece 1.
