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 preferably radially moving the main jaws towards and away from each other,
- wherein the transmission has a drive unit having two pairs of drivable entrainment members, wherein the entrainment members
- are mounted movably, preferably 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 that a relative movement of the entrainment members, of a respective pair with the same movement components relative to each other causes a synchronous movement of adjacent main jaws and that both a relative movement of the entrainment members 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 relative to each other.
