Abstract
The present invention relates to a coupling system for use at a spindle apparatus of a machine tool, comprising an energy transmission unit with a transmitter coil unit for the contact-free transmission of electrical energy to a receiver coil unit of a tool interface unit with an electrical load and a tool interface portion for accommodation in a tool support of a work spindle of the spindle apparatus, and a coupling interface unit having an interface body element attachable to the spindle apparatus and a second coupling element which is configured to be coupled to a first coupling element of the energy transmission unit by means of a releasable connection.
Claims21
A system for use with a spindle apparatus of a machine tool, comprising:
- an energy transmission unit having a transmitter coil unit for contact-free transmission of electrical energy to a receiver coil unit of a tool interface unit, the tool interface unit including:
- the receiver coil unit;
- an electrical load;
- and
- a tool interface portion configured to be received by a tool support of a work spindle of the spindle apparatus;
- and
- the system further comprising:
- a coupling interface unit having an interface body element configured to be releasably attached to the spindle apparatus,
- wherein the coupling interface unit includes a second coupling element configured to be releasably coupled to a first coupling element of the energy transmission unit;
- and
- wherein the coupling interface unit has an electrically, hydraulically, or pneumatically controllable locking mechanism for unlocking and locking the releasable connection between the first and second coupling elements.
