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.
Claims19
An apparatus for removing rubber stator material from inside a housing, the apparatus comprising:
- a head being passable at least partially inside the housing along a longitudinal axis;
- at least one drive configured to concurrently impart rotation about the longitudinal axis and translation along the longitudinal axis between the head and the housing;
- 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 longitudinal axis and being configured to remove the rubber stator material at least partially from inside the housing along the longitudinal axis in response to the concurrently imparted rotation and translation;
- 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.
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 longitudinal 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, the actuator comprising:
- a piston having a shoulder disposed on the head, the shoulder being movable against the at least one blade;
- a source disposed in fluid communication with the piston and supplying fluid pressure to the piston;
- and
- a shaft on which the head is disposed, the shaft communicating the fluid pressure from the source to a pressure chamber of the piston disposed on the shaft, wherein the shoulder is movable against the at least one blade in response to the fluid pressure supplied from the source to the piston.
