Abstract
A feeding unit for feeding an element to a treatment unit of a machine tool, in particular for feeding a rivet to a riveting unit, has a gripping element provided for the fastening element for the automatic take-up of the fastening element from a supply unit and automatic feed to the treatment unit. The gripping element is disposed on a rotary element rotatable about an axial direction, and at least one electromagnet is provided which is configured in such a way that a torque acting on the rotary element is generated by a magnetic force.
Claims12
A feeding unit for feeding a fastening element to a treatment unit of a machine tool, the feeding unit comprising:
- a guide tube;
- a rotary element mounted within said guide tube and being rotatable about an axial direction, said rotary element being axially displaceable and telescopically guided in said guide tube, said rotary element having a first end and a second end opposite said first end;
- a permanent magnet fixed on said rotary element at said second end of said rotary element;
- said guide tube having magnet coils disposed thereon, said magnet coils being disposed such that during an axial displacement of said rotary element, said permanent magnet being axially displaceable to an axial position of said magnetic coils for providing a magnetic force producing a torque on said rotary element to rotate said rotary element;
- and
- a gripping element for automatically taking-up of the fastening element from a supply unit and automatically feeding the treatment unit, said gripping element disposed on said rotary element at said first end.
