ABSTRACT:
A pneumatically actuated clamp and gripper including a fluid actuated piston and cylinder assembly and a clamp arm supported for pivotal movement and having a moving end for clampingly engaging a workpiece. The clamp includes a link having one end pivotally connected to the clamp arm for causing movement of the clamp arm and the other end of the link being connected to the piston. The clamp also includes a frame assembly for supporting the clamp arm for pivotal movement, the frame assembly including a pair of frame halves clamped together in face-to-face relation and housing the projecting end of the piston and clamp arm therebetween. The frame assembly includes a pair of pivot pin bores for selectively and alternatively supporting the clamping arm for pivotal movement about a first pivot axis and a second pivot axis. The clamp also includes a roller assembly for supporting the drive member connected to the link for reciprocating movement and for preventing wear of the drive member and the frame components.
