In a device for clamping a workpiece, such as an undressed casting, so that various surfaces of the workpiece can be mechanically worked, a platform having a support surface for the workpiece is pivotally mounted on a horizontal first axle located below the support surface. The first axle is pivotally mounted in a first cup-shaped housing which, in turn, is mounted for rotation about a vertically extending second axle. The first housing is pivotally supported within a second cup-shaped housing which is secured by swivel arms to a horizontal third axle located above and extending normally of the first axle. With the workpiece located on the support surface of the platform, the position of the surface to be worked is sensed to determine any deviations from a nominal position and by pivoting the platform about the three axles the surface can be precisely located for the working operation. |

DETAILED DESCRIPTION OF THE INVENTION In FIGS.
1, 2 and 3 a device is illustrated for the aligned clamping of a workpiece shown schematically and the device includes a platform 1 mounted for rotation about three separate axles 3, 4 and 5.
Platform 1 is rigidly connected by webs 21 with the first axle located below and in parallel with the horizontal clamping surface 2 of the platform.
First axle 3 is pivotally mounted in bearings 22, 23 located in an inner cup-shaped housing 9.
A rotational drive 7 is directly connected to the axle 3.
Inner housing 9 is pivotally mounted by means of a ring-shaped bearing 10 located on the upper edge 32 of the housing for rotation about the second axle 4 which extends vertically below the housing.
A rotational drive 8 is connected directly to the axle 4 and is supported on the lower surface of an outer cup-shaped housing 11.
Outer housing 11 laterally encloses the inner housing 9 and it is supported from the axle 5 by arms 12 located on opposite sides of the housing.
The axle 5 is pivotally mounted in two bearings 24, 25 of a frame 20, not otherwise shown.
The axles 3, 4 and 5 extend perpendicularly to one another, with axle 5 being disposed horizontally in the represented embodiment.
It would also be possible to position the third axle 5 vertically.
Rotational drive 6, mounted directly on the frame 20, drives the third axle 5.
The rotational drives 6, 7 and 8 are preferably hydraulic rotary drives, however, other types of hydraulic or pneumatic drives can be used.
Function generators 17, 18 and 19 are used to indicate the pivoted positions of the axles 3, 4 and 5.
In FIG.
5 another embodiment is shown of the rotational drive for the first axle 3.
Platform 1 is connected eccentrically to a linear variable drive 30 for rotation about the axle 3.
The drive, as shown, is a hydraulic cylinder pivotally mounted on frame 20 and operatively connected to a linear transmitter 31.
By a pivotal movement of drive 30, its connection to the platform 1 can be released and the platform can be rotated into a vertical position by turning it about the third axle 5
