Vacuum Chuck

In the manufacture of subminiature components it often is necessary to handle thin fragile metal or ceramic plates.

This chuck quickly and securely holds such plates without fracture. It has circular base plate 10 of toroid configuration provided with holes for screws 11. Circular cover plate 12 is formed with circular groove 14 in the upper surface to accommodate resilient O-ring 15. The under surface of the cover is dished to form a cavity 16, the edges of which are recessed to receive a disk 17 of spring material.

Diaphragm 18 of resilient material such as rubber is secured between the cover and base over disk 17. pins 20 are in the cover for positioning plate 21. Hole 22 is in the cover communicating with cavity 16, which, when a vacuum is created in the cavity, by flexing diaphragm 18, reduces the pressure on the underside of the plate within the area of the 0-ring to firmly hold the plate.
