ABSTRACT:
The invention relates to a rapid clamping system (50), comprising a clamping housing (12), with a piston (18) acted on from one side by springs (15) and which may be pressurised from the other side, with an actuator (60) arranged on the piston (18) to follow the piston movement, with at least one clamping bolt (32) arranged to be displaced perpendicular to the piston axis (28), in a working coupling acting in both directions of displacement with the actuator (60) by means of an inclined guide (52), whereby, with the springs (16) extended, the clamping bolt (32) takes up a locking position for locking a clamping pin (14) which may be introduced in the clamping housing (12) and which adopts an unlocking position for removal of the clamping pin (14) on corresponding pressurization of the piston (18). The invention is characterized in that the inclined guide (52) has an irregular guide contour (54) with varying angles of inclination (α, β, γ, δ) relative to the piston axis (28) to achieve varying translation ratios.
