Abstract
An expansion tool includes a housing, a collar rotatably coupled to the housing, the collar including a plurality of slots, a plurality of jaws, each jaw having a projection received in a corresponding one of the plurality of slots such that the jaws are coupled for co-rotation with the collar, a mandrel moveable relative to the housing between a retracted position and an extended position, the mandrel engageable with the jaws to expand the jaws in response to movement of the mandrel to the extended position, and a cone received within the plurality of jaws and engageable with inner surfaces of the plurality of jaws. The mandrel is configured to engage the cone to move the cone with the mandrel to expand the jaws as the mandrel moves toward the extended position, and a rotation mechanism is configured to incrementally rotate the collar.
