Abstract
A workpiece holder device for workpieces to be machined on multiple sides, wherein the workpiece can be held axially and radially relative to the first axis between a first workpiece holder, operatively connected to at least one support spindle of the workpiece holder device and rotatable about a first axis, and at least one second workpiece holder, operatively connected to at least one drive spindle of the workpiece holder device and rotatable around the first axis, by force locking by a clamping force which can be built up in the manner of a vice between the first workpiece holder and the second workpiece holder in the axial direction of the first axis and acting on the opposite sides of the workpiece.
Claims27
A workpiece holder device for workpieces to be machined on multiple sides, the workpiece holder device comprising:
- a first workpiece holder operatively connected to at least one support spindle and rotatable about a first axis (R),
- at least one second workpiece holder operatively connected to at least one drive spindle and rotatable around the first axis (R), and
- at least one locking means;
- wherein, in operation, the workpiece can be held axially and radially relative to the first axis (R) between the first workpiece holder and the second workpiece holder by a clamping force which can be built up in the manner of a vice between the first workpiece holder and the second workpiece holder in the axial direction of the first axis (R) and acting on the opposite sides of the workpiece,
- wherein the first workpiece holder comprises at least one first clamping element with a first smooth clamping face facing towards the second workpiece holder and the workpiece and the second workpiece holder comprises at least a second clamping element with a second smooth clamping face facing towards the first workpiece holder and the workpiece,
- wherein the at least one locking means is configured to enable at least one of the first workpiece holder and the first clamping element to be lockable in at least one predetermined rotational position about the first axis, and
- wherein the at least one locking means comprises a locking element moveable from a release position into a locking position to enable at least one of the first workpiece holder and the second workpiece holder to be movable from a rotational position different from the predetermined rotational position into the predetermined rotational position.
A workpiece holder device for workpieces (105) to be machined on multiple sides, the workpiece holder device comprising:
- a first workpiece holder operatively connected to at least one support spindle and rotatable about a first axis (R), and
- at least one second workpiece holder operatively connected to at least one drive spindle and rotatable around the first axis (R),
- wherein, in operation, the workpiece can be held axially and radially relative to the first axis (R) between the first workpiece holder and the second workpiece holder by a clamping force which can be built up in the manner of a vice between the first workpiece holder and the second workpiece holder in the axial direction of the first axis (R) and acting on the opposite sides of the workpiece,
- wherein the first workpiece holder comprises at least one first clamping element with a first smooth clamping face facing towards the second workpiece holder and the workpiece and the second workpiece holder comprises at least a second clamping element with a second smooth clamping face facing towards the first workpiece holder and the workpiece,
- wherein the first clamping element and the second clamping element are constructed of a plurality of parts, wherein a first clamping element part of a particular clamping element can be moved relative to the second clamping element part of the clamping element in such a manner that a first angle (α′) between the first axis (R) and the normal direction of the first clamping face and a second angle between the first axis and the normal direction of the second clamping face can be varied;
- wherein the first clamping element part is in contact with at least one second contact surface of the second clamping element part in the region of at least one first contact surface, and wherein the first axis (R) is defined by a center of gravity of the first contact surface or a center of gravity of the second contact surface, and wherein the first contact surface is smaller than the second clamping element part facing first surface of the first clamping element part or the second contact surface is smaller than the second surface of the second clamping element part facing the first clamping element part.
