The device is designed to equip fixed or mobile posts for assembling vehicles, or clamping arms.
Claims8
A centring and clamping device for a sheet-metal assembly or a mechanical part along three orthogonal axes, the device comprising a hollow pilot, for geometric centring along two orthogonal axes, fitted with at least two retractable hooks for geometric clamping along a third orthogonal axis, articulated on axes and powered by a piston which slides inside the hollow pilot, the retractable hooks provided with lugs and the piston provided with a driving groove which permits the drive in rotation of the hooks through the lugs;
- the device further comprising a supporting nosepiece which determines the supporting face of the part to be clamped, on which are mounted the pilot, the hooks and the piston, and also comprising a washer inserted between the fixing face of the pilot and the base of the supporting nosepiece, the washer being provided for the adjustment of the thickness of the part to be clamped, by modification of its thickness.
