Abstract
A workpiece holding device for holding a workpiece having a substantially radial inner surface and a substantially radial outer surface in a heat treatment system while the workpiece undergoes a thermal expansion and/or contraction, the workpiece holding device includes at least two clamping units configured to apply a radial clamping force to the workpiece to hold the workpiece in the workpiece holding device in a predefined position, each of the at least two clamping units including a clamping element configured to abut against the radially inner surface and/or against the radially outer surface of the workpiece and to apply a radial clamping force to the workpiece.
Claims18
A workpiece holding device for holding a workpiece having a substantially radial inner surface and a substantially radial outer surface in a heat treatment system while the workpiece undergoes a thermal expansion and/or contraction, the workpiece holding device comprising:
- at least two clamping units configured to apply a radial clamping force to the workpiece to hold the workpiece in the workpiece holding device in a predefined position, each of the at least two clamping units including a clamping element configured to abut against the radially inner surface and/or against the radially outer surface of the workpiece and to apply a radial clamping force to the workpiece and
- a drive unit configured to rotate the workpiece held in the workpiece holding device, the drive unit comprising a friction wheel or a friction roller configured to abut against the workpiece such that a rotation of the friction wheel or the friction roller is frictionally imparted to the workpiece to move a fixed point on the workpiece relative to the at least two clamping units.
A workpiece holding device for holding a workpiece having a substantially radial inner surface and a substantially radial outer surface in a heat treatment system while the workpiece undergoes a thermal expansion and/or contraction, the workpiece holding device comprising:
- at least two clamping units configured to apply a radial clamping force to the workpiece to hold the workpiece in the workpiece holding device in a predefined position, each of the at least two clamping units including a clamping element configured to abut against the radially inner surface and/or against the radially outer surface of the workpiece and to apply a radial clamping force to the workpiece, wherein each of the clamping elements has a rotational axis, and wherein each of the clamping elements is configured to abut against the workpiece, and wherein the rotational axis of the clamping element is substantially parallel to an axis of rotation of the workpiece.
