Abstract
The chain magazine for holding tool'(5) for machine tool'includes a continuous chain (1) which has chain links (2) each with at least one tool holder (2a, 2b) and with which at least one sprocket (6, 7) meshes and a guide device (9-12) which has a guide element (12) that can be moved back and forth between a first and a second position, by means of which a tool holder (2a, 2b) of a chain link (2) can be turned in and turned out.
Claims11
A chain magazine for holding took for a machine tools comprising:
- a continuous chain which has chain links forming a rotating chain having an inner side and an outer side, each chain link having a first tool holder and a second tool holder, a transfer station at which a tool from the first tool holder is gripped by a tool changer, the first tool holder having a first axis of rotation, the second tool holder having second axis of rotation, at least one sprocket which is configured to mesh with and drive the chain to carry a given chain link to the transfer station, a guide device for guiding the chain, and a guide element that can be moved back and forth between a first inward position and a second outward position to pivot the given chain link about the second axis of the second tool holder and turn out the given chain link to displace the first tool holder outwardly to the second outward position to facilitate gripping of a tool in the first tool holder by the tool changer.
