摘要:
An ID chuck is defined by a rotating tube pushed or pulled by a left hand cylinder and piston. The tube moves an extender cooperating with a plug surrounded by a set of collet fingers. The fingers move radially to lock a workpiece against a registration surface, and move inwardly to release the workpiece.
摘要:
An expansible mandrel constructed to radially expand equally comprising a generally truncated polyhedron-shaped core member and a plurality of wedge members defining a cylinder, the core member being axially movable relative to the wedge members. Elastic means surrounding the wedge members maintain the wedge members in position relative to the core member.
摘要:
A workpiece holder includes a plurality of elements movable radially outwardly into engagement with an inner surface of an annular workpiece in response to movement of a cam.
摘要:
An expansible shaft including a hollow axially-extending body and operatively coupled core engaging and retracting sections within the body. The core engaging section includes a core engager movable relative to the body in a direction generally perpendicular to the axis of the body and biased towards a core engagement position in which it projects beyond the wall of the body; and the retracting section includes an actuator arranged to overcome the bias and move the core engager radially inwardly from its core engagement position.
