Abstract
A system pendulum apparatus (13) is provided for a chuck and a method is provided for the clamping of workpieces with a pendulum element (16) and a basal element (30). An axially swivelable connection is provided between the pendulum element and the basal element by way of an element connection device. A swivel range a of the pendulum element can be restricted by a restriction device (39), and the pendulum element can be returned by a return device to a central position of the swivel range. The pendulum element can be fixed within the swivel range by a fixing device (23). The basal element can be joined by a joining device to one jaw of a chuck (10). The pendulum element has a clamping device with two exchangeable clamping elements (20), which are displaceable and fixable.
Claims18
A system pendulum apparatus for a chuck or the like, the apparatus comprising:
- a pendulum element;
- a basal element;
- an element connection device for providing an axially swivelable connection between the pendulum element and the basal element, the connection device comprising a restriction device for restricting a swivel range of the pendulum element, a return device for returning the pendulum element to a central position of the swivel range, a fixing device for fixing that the pendulum element within the swivel range, wherein the basal element can be joined by means of a joining device to one jaw of a chuck, and the pendulum element has a clamping device with two exchangeable clamping elements, which are slideable and fixable, said clamping elements being mounted on said pendulum element and slidable in a linear direction with respect to said pendulum element;
- said pendulum element swivels about a swivel axis with respect to said basal element;
- said linear direction of said clamping elements is in a plane perpendicular to said swivel axis.
A chuck for clamping of workpieces or the like, the chuck comprising at least three system pendulum apparatuses, each pendulum apparatuses comprising:
- a pendulum element;
- a basal element;
- an element connection device for providing an axially swivelable connection between the pendulum element and the basal element, the connection device comprising a restriction device for restricting a swivel range of the pendulum element, a return device for returning the pendulum element to a central position of the swivel range, a fixing device for fixing that the pendulum element within the swivel range, wherein the pendulum element has a clamping device with two exchangeable clamping elements, which are slideable and fixable and wherein the system pendulum apparatuses are each displaceable and fixable by means of a joining device at jaws of the chuck, said clamping elements being mounted on said pendulum element and slidable in a linear direction with respect to said pendulum element;
- said pendulum element swivels about a swivel axis with respect to said basal element;
- said linear direction of said clamping elements is in a plane perpendicular to said swivel axis.
A method for clamping of workpieces, the method comprising the steps of:
- providing a pendulum element;
- providing a basal element;
- providing an element connection device for providing an axially swivelable connection between the pendulum element and the basal element, the connection device comprising a restriction device for restricting a swivel range of the pendulum element, a return device for returning the pendulum element to a central position of the swivel range, a fixing device for fixing that the pendulum element within the swivel range, wherein the pendulum element has a clamping device with two exchangeable clamping elements, which are slideable and fixable and wherein the system pendulum apparatuses are each displaceable and fixable by means of a joining device at jaws of a chuck and wherein for clamping of a workpiece the chuck having at least three system pendulum apparatuses is used, said clamping elements being mounted on said pendulum element and slidable in a linear direction with respect to said pendulum element;
- said pendulum element swivels about a swivel axis with respect to said basal element;
- said linear direction of said clamping elements is in a plane perpendicular to said swivel axis.
