Marked ring gripper for handling of e.g. annular workpieces, has set of gear wheels rotating on circular path by coarse thread spindle becoming set of link stones to move set of chuck jaws when set of slots is closed

摘要

The gripper has a coarse thread spindle rotated by an axial moved segment-shaped piston. A set of gear wheels (1) rotating on a circular path by a coarse thread spindle becomes a set of link stones to move a set of chuck jaws working against each other in linear led pairs of chuck jaws when a set of slots to engage and flow power at a wall of an annular workpiece is closed. The segment-shaped piston, coarse thread spindle, gear wheels, link stones and pairs of chuck jaws are displaced three times around 120 degrees. A set of annular workpiece locations is displaced around 120 degrees.
