A clamp having a lock is provided. In another aspect, a fail safe lock maintains the position of a clamping member when fluid pressure or other actuating power is undesirably reduced. Another aspect employs teeth on a locking structure which engage matching teeth on a shaft where engagement of the teeth prevent unclamping of a workpiece. In still another aspect, a manual override member disengages a lock in order to unclamp a workpiece.

Pin clamp

A clamp includes a body, a lead pin moveable relative to the body and an actuator supported by the body. The actuator is axially moveable between an extended position and a retracted position. The actuator includes a camshaft drivingly coupled to the lead pin. Axial movement of the camshaft causes the lead pin to rotate between a first positioned aligned with a first longitudinal axis and a second position aligned with a second longitudinal axis laterally offset from the first longitudinal axis.

Rotating head pin clamp

Disclosed is an automatically equalizing press for sequential operations on opposite sides of a workpiece. The press is designed to allow a pair of punch-anvil combinations to work on opposing sides of the workpiece without substantially deforming the workpiece prior to the final, e.g. piercing, operation. One tool from each combination is mounted on a slide block which is capable of movement independent of the other slide block. The slide blocks are operable by fluid actuated pistons.
