Abstract
The gripping device has two gripping arms which are directly connected to one another in a pivotable manner about a common axis. A stop member is positioned in front of the pivot axis. Both gripping arms are pivotally connected to a piston rod of a piston-cylinder unit via toggle levers. The piston rod is displaceable relative to the pivot axis so that the gripping arms can be extended in a single displacement movement and pivoted into their gripping position.
Claims9
A gripping device for gripping tools, workpieces or the like, comprising:
- (a) a housing,
- (b) a pair of gripping arms, mounted in said housing, said arms being pivotally mounted to each other adjacent their inner ends about a pivot axis,
- (c) piston-cylinder means movable longitudinally in said housing,
- (d) lever means pivotally connected both to said piston-cylinder means and to said gripping arms in such a manner that said piston-cylinder means is longitudinally displaceable relative to said pivot axis, and
- (e) stop means on said housing in alignment with said pivot axis and forwardly thereof, whereby
- forward movement of said piston-cylinder means causes said gripping arms to move correspondingly forward until said gripping arms in the region of said pivot axis engage said stop means, with continued movement of said piston-cylinder means causing said lever means to rotate and move said gripping arms into a gripping position.
