GANIC EQUIPMENT FOR THE CENTRATION AND BLOCKING OF PEZZI, PARTICULARLY LAMIERA FLOWERS.

摘要

A hook apparatus for centering and clamping workpieces, particularly metal sheets, comprises a main body (12) defining a resting zone (62) of a workpiece, a hooking member (19) movable between a resting position spaced from the resting zone (62) and at least one clamping position close to the resting zone (62), and members for controlling the movement of the hooking member (19) such as to allow workpieces of different thickness to be locked. The control means include a control rod (20) slidable with respect to the main body (12) between a lowered position and a raised position, at least one L-shaped member (32) articulated to a part (22) connected to the rod (20), and guide elements (36, 46, 48) to keep a predetermined orientation of the hooking member (19). The part connected to the rod (20) includes an auxiliary body (22) fixed to the rod (20), having a slit (24) in which a slidable pin (26) is engaged, which also engages a hole (30) of an arm of the L-shaped member (32).
