Abstract
A compensating chuck for concentrically clamping workpieces. The chuck has a drive unit having two pairs of entrainment members, wherein the entrainment members are preferably slidingly mounted, are respectively movable in paired relationship, and are so coupled to a respective one of the main jaws that a relative movement of a respective pair causes a synchronous movement of adjacent main jaws and that both a relative movement relative to each other with respectively different movement components and also a synchronous movement of the adjacent entrainment members in the same direction respectively causes a relative movement of adjacent main jaws.
Claims25
A compensating chuck for concentrically clamping workpieces, comprising:
- a housing;
- two pairs of mutually diametrically opposed main jaws for receiving corresponding clamping jaws;
- and
- a transmission for radially moving the main jaws towards and away from each other,
- wherein the transmission has a drive unit having two pairs of adjacent drivable entrainment members, wherein the entrainment members:
- are mounted slidingly in the housing such that the entrainment members move only in a sliding manner relative to the housing, the movement only in a sliding manner being defined by movement along only a single direction for each entrainment member,
- within each pair are respectively slidable towards and away from each other, and
- are so coupled to a respective one of the main jaws such that a relative sliding movement of the entrainment members within the respective pair with the same movement components relative to each other causes a synchronous movement of adjacent main jaws;
- and such that both a relative sliding movement of the entrainment members within each pair relative to each other with respectively different movement components and also a synchronous sliding movement of the adjacent entrainment members in the same direction respectively causes a relative movement of adjacent main jaws relative to each other,
- wherein one of the main jaws or the entrainment members has a sliding guide in which a corresponding projection of the other of the main jaws or one the entrainment members is guided, without play.

A compensating chuck for concentrically clamping workpieces, comprising:
- a housing;
- two pairs of mutually diametrically opposed main jaws for receiving corresponding clamping jaws;
- and
- a transmission for radially moving the main jaws towards and away from each other,
- wherein the transmission has a drive unit having two pairs of drivable first entrainment members, wherein the first entrainment members:
- are mounted slidingly in the housing,
- are respectively movable towards and away from each other in paired relationship, and
- are so coupled to a respective one of the main jaws such that a relative movement of the first entrainment members, of a respective pair with the same movement components relative to each other causes a synchronous movement of adjacent main jaws;
- and such that both a relative movement of the first entrainment members relative to each other with respectively different movement components and also a synchronous movement of the adjacent first entrainment members in the same direction respectively causes a relative movement of adjacent main jaws relative to each other,
- wherein the first entrainment members are movable in a first horizontal plane parallel to a first axis (A) and the main jaws are movable in a main jaw plane parallel to the first plane,
- wherein the compensating chuck has a set of second entrainment members mounted slidingly in the housing, and
- wherein the first entrainment members are mounted slidingly, in the housing, by guide means provided on the first entrainment members.
