Abstract
An apparatus for removing rubber stator material from inside a housing includes a head, at least one blade, and an actuator. For example, the apparatus can be used to core out rubber material from the housing so new material can be molded therein. Also, the apparatus can be used to cut back excess rubber material newly molded in the housing. The head is rotated about an axis and is moved along the axis relative to the housing. The at least one blade is pivotably connected to the head and removes the rubber stator material at least partially from inside the housing with the rotation and movement of the head through the housing. The actuator is associated with the at least one blade and is operable to adjust a pivot of the at least one blade relative to the head.

An apparatus for removing rubber stator material from inside a housing, the apparatus comprising:
- at least one drive configured to impart rotation about a longitudinal axis;
- a head being passable at least partially inside the housing along the longitudinal axis of the imparted rotation;
- at least one blade pivotably connected at a pivot point to the head, the at least one blade being pivotable about the pivot point at a plurality of pivot positions relative to the axis and being configured to remove the rubber stator material at least partially from inside the housing along the longitudinal axis of the imparted rotation;
- and
- an actuator associated with the at least one blade and being configured to adjust the at least one blade to any one of the pivot positions relative to the longitudinal axis.
A method of removing rubber stator material from inside a housing, the method comprising:
- rotating at least one of a head and the housing about a longitudinal axis;
- passing the head at least partially inside the housing along the longitudinal axis;
- adjusting at least one blade on the head to any one of a plurality of pivot positions relative to the longitudinal axis;
- engaging the at least one blade on the head against the rubber stator material inside the housing;
- and
- removing the rubber stator material at least partially from inside the housing with the engagement.
