Abstract
A self-clamping torque adapter comprises a tool base, a central hub, a plurality of clamps, and a cam actuator mechanism. The tool base has a central axis and the central hub is rotatably coupled to the tool base and configured to rotate relative to the tool base about the central axis. The central hub comprises a torque input member configured to receive a torque input. The plurality of clamps are slidably coupled to the tool base, and configured to displace bi-directionally along a radial axis. The cam actuator mechanism couples each of the plurality of clamps to the central hub. Rotation of the central hub relative to the tool base causes the cam actuator mechanism to move each of the plurality of clamps in a radial direction.
