<p>A clamp pin tool holder (10) for clamping an insert (18) in a tool holder includes a bore (19) for receiving a clamp pin (20) and a bore (15) for receiving a lock screw (30). The clamp pin (20) includes a cam portion (22) with angled surfaces (28b, 28c). The lock screw (30) is rotatably mounted to the bore (15) of the tool holder (10) and includes angled surfaces (32c, 34c) for engaging the angled surfaces (28b, 28c) of the clamp pin (20). When the lock screw (30) is rotated in one direction, one angled surface (32c) on the lock screw (30) and one angled surface (28b) on the clamp pin (20) engage each other and acts as a conical wedge to cause the clamp pin to move relative to the lock screw. When the lock screw (30) is rotated in the opposite direction, another angled surface (34c) on the lock screw engages a different angled surface (28c) on the clamp pin (20) in a similar manner to cause the clamp pin (20) to move in an opposite direction.</p> |
