ABSTRACT:
A clamp structure that has a jaw mounted on a shaft with the clamping face of the jaw facing along the direction of the shaft and offset from it applies clamping force to a work piece when a cam that is part of the clamp structure is moved by an actuator from a free position to a clamping position. The cam is connected to the shaft and has a cam surface that applies force to a follower in opposition to a biasing spring when the actuator is so moved, and a mounting device holds the shaft between the follower and the spring.
