Device to clamp a workpiece in a definite position in a working area of a machine tool |
摘要 |
<p>The unit (1) has a chuck (1) to clamp a work piece support, with a centring pin (22) on the chuck co-operating with second positioning devices on the work piece support. The pin and second positioning devices co-operate in pairs as alignment elements and position the work piece support in three orthogonal axes and the desired angle. A clamp device (12,18) fixes the clamping force of the work piece support in position at the chuck. The clamp device has a number of clamping balls (18) and an annular groove. The line of the clamping force of the clamp device lies in a cylindrical casing surface (MF) of the chuck, which is parallel the chuck axis (Z) and intersects the centring pin and second positioning devices.</p> |
