Abstract
A tool joint clamp which includes a clamp assembly and a stop ring. The clamp assembly has at least two die carriers, with each die carrier having a translating and pivoting link between the die carriers such that the die carriers may move toward and away from a centerline of the clamp assembly. The stop ring includes a ring body having a central aperture forming an internal sidewall, with at least a portion of the internal sidewall having splines. A cam surface and cam follower are positioned between the clamp assembly and the stop ring, with the cam surface and cam follower configured to urge the die carriers toward the clamp assembly's centerline when relative torque is applied between the clamp assembly and the stop ring.
