Abstract: An electric clamp apparatus includes a body, a rotary drive unit which is driven rotatably by an electric signal, and a clamp arm disposed rotatably with respect to the body. By driving the rotary drive unit, a drive force is transmitted to the clamp arm through a drive force transmission mechanism, whereby the clamp arm is rotated via a link arm through a predetermined angle with respect to the body, and a workpiece is clamped between the clamp arm and a support member of the body. Further, rotational operation of the clamp arm is regulated by abutment of a sub-roller against an inclined portion of a displacement body.

Abstract: A workpiece holder for selectively mounting a workpiece along x, y and z axes is provided. A stationary base clamp includes a first protrusion extending from a first top surface having a first contact surface positioned at an acute angle relative to the first top surface. A clamp dog is slidably disposed within a partial slot defined in the base clamp and includes a second protrusion extending from a second top surface. The second protrusion may include second and third contact surfaces that are both positioned at an acute angle relative to the second top surface. An adjustment mechanism operatively connects the base clamp and clamp dog to selectively move the workpiece holder between clamped and release positions. In particular, the second protrusion is moved away from the first protrusion to the clamped position so that the contact surfaces engage a dovetail wall of a recess formed in the workpiece.
