Encapsulated lever-operated chuck has lever on plate, toggle links, and double pistons, to apply high clamping force and maintain it when compressed air supply fails

摘要

The tool has an interchangeable lever (1) fastened to a plate (2) in a closed housing, and moved via toggle links (4,5,6). A piston (7) supports itself on a roller (11) when the lever builds up a load. The tool has double pistons (8,10) and a contact-free position indicator (12). The lever fastening on the plate is variable, so that the clamping force can used vertically or horizontally.
