Abstract
A tool operable to expand an end of a pipe, such as PEX pipe, has a jaw assembly with jaws movable between a closed position and an expanded position and rotatable about a longitudinal axis. A motor drives an output spindle driven by the motor, which in turn drives a radial cam. A wedge is movable by the radial cam in a reciprocating motion along the axis, causing the wedge to move between a first position where the jaws are in the closed position and a second position where the jaws are in the expanded position. A rotating ring is mounted on the wedge and connected to the jaws. The rotating ring is driven by the output spindle for rotating the jaws about the axis.
Claims16
A tool operable to expand an end of a pipe, the tool comprising:
- a housing;
- a jaw assembly disposed on the housing, the jaw assembly comprising a plurality of jaws rotatable about an axis and movable between a closed position where portions of the plurality of jaws are adjacent to the axis, and an expanded position where the portions are moved away from the axis;
- a motor disposed in the housing;
- an output spindle driven by the motor;
- a radial cam connected to the output spindle;
- a wedge movable by the radial cam in a reciprocating motion along the axis;
- an index cam connected to the output spindle;
- a shaft connected to the index cam;
- a rotating ring mounted on the wedge;
- a clutch ring mounted on the wedge and engaging the rotating ring;
- and
- a gear ring driven by the shaft and slidably engaging the clutch ring;
- wherein the wedge is movable between a first position where the plurality of jaws are in the closed position and a second position where the plurality of jaws are in the expanded position.
