Robot-controlled gripping chuck e.g. for a post sole plate assembly system has components to form rotary coupling between base and gripper under axial effort

摘要

The chuck (31), comprising a base (310) and a gripping section (311, 312) that is fixed relative to the base in the absence of effort, incorporates a series of components (315, 316, 317, 318) that form a rotary coupling between the base and gripping section under an axial effort that pushes them together, overcoming the force of springs (313, 314). It incorporates a plate (315) that co-operates with a collar in the absence of effort, disengaging from it when the base and gripping section move towards one another.
