Abstract
The invention relates to a device for damping vibrations and/or controlling the flexion of an object in machining, said device comprising at least one force exchange device which could be a force applying device or a damping device. A such force applying device is for applying a force having a force component directed at right angles to the surface of the object and/or for applying a moment to the object. A damping device of this type is for absorbing vibrations from the object and is adapted to absorb a force component directed at right angles to the surface of the object or to absorb a moment from the object.
Claims21
A device for vibration damping and/or controlling the flexion of an object in machining, wherein the object is a tool, tool holder or workpiece, the device comprising:
- at least one force exchange device external of a surface of the object and wherein said force exchange device comprises at least one actuator attached to a locator sleeve and a mechanical lever surrounding the object, the locator sleeve with the at least one actuator and mechanical lever are movable along an outer surface of the object, and wherein the at least one force exchange device is operative to either
- exchanging a force having a force component directed at right angle to the surface of the object, or
- exchanging directly or via the mechanical lever, a moment between the object and the device.
A device for vibration damping and/or controlling the flexion of an object in machining, the device comprising:
- a locator sleeve having an inner portion and an outer portion, wherein the inner portion is disposed around an outer surface of the object;
- a force transmission sleeve having an inner portion and an outer portion, wherein the inner portion is disposed around the outer surface of the object;
- and
- at least one force exchange device attached to the outer portion of the locator sleeve and the outer portion of the force transmission sleeve, wherein the locator sleeve, the force transmission sleeve and the at least one force exchange device are movable along the outer surface of the object and wherein the at least one force exchange device is operative to either
- exchange a force having a force component directed at right angle to the surface of the object, or
- exchange directly or via the force transmission sleeve, a moment between the object and the device.
A device for vibration damping and/or controlling the flexion of an object in machining, the device comprising:
- a locator sleeve connected to a side of a tool clamp, wherein the tool clamp is attachable to a surface of the object;
- a force transmission sleeve in contact with the object;
- and
- at least one force exchange device attached between the locator sleeve and the force transmission sleeve, wherein the at least one force exchange device is operative to either
- exchange a force having a force component directed at right angle to the surface of the object, or
- exchange directly or via the force transmission sleeve, a moment between the object and the device.
