Abstract
A clamping assembly for a clamping device for clamping of a workpiece or tool or a toolholder on machine component with a clamping cone movable axially via a tension rod and several clamping elements arranged spaced from each other in the peripheral direction on the outside of the clamping cone, which can be moved between a radially outer clamped position and a radially inner released position by axial movement of the tension rod. The clamping cone includes two parts movable opposite each other in the axial direction.
Claims12
A clamping assembly for a clamping device for clamping of a workpiece or tool or a toolholder on machine part, the clamping assembly comprising a clamping cone movable axially via a tension rod and a plurality of clamping elements arranged spaced from each other in a peripheral direction on an outside of the clamping cone, which are movable between a radially outer clamped position and a radially inner released position by axial movement of the tension rod, wherein the clamping cone has first and second parts movable opposite each other in an axial direction and wherein the clamping elements have a first inner clamping surface for contact on a conical outer surface of the first part of the clamping cone and a second inner clamping surface for contact on a conical outer surface of the second part of the clamping cone.
A clamping device for clamping of a workpiece or tool or toolholder on a machine part with a clamping assembly arranged within the machine part and an activation device connected to the clamping assembly,
- wherein the clamping assembly comprises a clamping cone movable axially via a tension rod and a plurality of clamping elements arranged spaced from each other in a peripheral direction on an outside of the clamping cone, which are movable between a radially outer clamped position and a radially inner released position by axial movement of the tension rod, the clamping cone having first and second parts movable opposite each other in an axial direction, and
- wherein the activation device contains a cylinder arranged within a housing, in which a first piston connected to the first part of the clamping cone via a first piston rod and a second piston connected to second part of the clamping cone via a second piston rod are arranged to move axially.
