Gripper METAL WORK

Parallel gripper: the jaws move in a straight line. There may be two, three or even four
iaws.
Hinged gripper: the jaws are hinged and move along the arc of a circle. It is generally cheaperthan a parallel gripper but there are some limitations (see drawing 1.6):
- If the part has varying dimensions, the contact area changes.
- If the part is cylindrical with varying dimensions, the position of the axis of the clamped part varies.
Gripper with retracting jaws: the jaws hâve an opening angle of about 90\ The clamping fingers can retract fully from the work top, and so, in certain cases, it is possible to avoid one linear retraction motion (see drawing 1.5).
Toggle gripper: a hinged gripper with a toggle-action mechanism to achieve high clamping forces. Clamping is irréversible even when there is no pressure, so the part cannot be released accidentally. The opening angle is 90e so it acts as retracting gripper. The clamping force is high within a limited angle only.
