Operating principle dead point mechanism

Skizze Funktionsprinzip GN 865

These pneumatically operated power clamps (Patent MISATI) are used for clamping, holding, gripping and positioning of work pieces in jigs and handling systems.

The salient points of these power clamps are:
• the high clamping force
• the small dimensions
• the reduced air consumption
• the light weight

The drawings shown here explain the functional principle of the dead point mechanism.

Pistons with diameters of 20, 32, 40 and 50 mm yield a clamping force of 60 Nm up to 475 Nm, which leads to clamping forces being much above those of competitors’ power clamps.

The power clamps have been designed and configured to achieve an extended life. Functional tests have proved that even after 20 million cycles they were still serviceable.

Further salient design points are:

• The clamp is kinematically designed such that self-retention (holding force FH) is achieved in the clamped position (clamping force FS) after passing the dead point due to irreversibility.

• The forward stroke sequence of the clamping arm is rapid but the ultimate clamping action is slow and as a result pneumatic damping is normally not required. Upon request, however, it can be supplied when big masses are moved.

• The clamping mechanism is fitted with needle bearings which give optimum clamping forces and reduced wear.

• The steel cylinder with the integrated clamping mechanism are in one unit. This leads to high stability for these small units with an extended range of applications. The placement of the air connection at the bottom end leads also to many other advantages.
