Power operated clamp assembly

A power operated clamp assembly comprising:

• a clamp body;
• a reciprocatable member extending into the clamp body and adapted to engage a driving means, the reciprocatable member being reciprocatable between extended and retracted positions, and the reciprocatable member having an end;
• a clamp arm mounted to the clamp body, the clamp arm being pivotally moveable and terminating its movement at first and second positions, the first and second positions being adjustable with respect to the clamp body;
• and
• a linkage assembly having a drive end and a clamp end, the drive end being adjustably secured to the end of the reciprocatable member, and the clamp end being operatively secured to the clamp arm so as to pivot the clamp arm between the first and second positions as the reciprocatable member reciprocates between the extended and retracted positions,
• wherein the drive end is adjustable with respect to the end of the reciprocatable member so as to allow adjustment of the first and second positions.

A power operated clamp assembly comprising:

• a clamp body;
• a reciprocatable member extending into the clamp body and adapted to engage a driving means, the reciprocatable member being reciprocatable between extended and retracted positions, and the reciprocatable member having an end;
• a first pivot element and a second pivot element, each pivot element defining a pivot axis;
• a clamp arm pivotally mounted to the clamp body by the first pivot element, the clamp arm being pivotally moveable about the pivot axis of the first pivot element,
• the clamp arm terminating movement at first and second positions, the first and second positions being adjustable with respect to the clamp body;
• and
• a linkage assembly including a connection pivotable about the pivot axis of the second pivot element, the linkage assembly having a drive end and a clamp end, the drive end being adjustably secured to the end of the reciprocatable member, and the clamp end being operatively secured to the clamp arm so as to pivot the clamp arm between the first and second positions as the reciprocatable member reciprocates between the extended and retracted positions,
• wherein the drive end is adjustable with respect to the end of the reciprocatable member so as to allow adjustment of the first and second positions, and
• wherein one pivot element of the first and second pivot elements includes an eccentric shaft having a central axis, the eccentric shaft including an axially extending eccentric portion, the eccentric portion defining the pivot axis of the one pivot element, the pivot axis of the one pivot element being displaced from the central axis of the one pivot element,
• the eccentric shaft being rotationally adjustably secured to the clamp body so as to allow angular adjustment of the pivot axis of the one pivot element with respect to the central axis of the one pivot element, thereby adjusting the first and second positions.
