Title:
METHOD AND DEVICE FOR FEEDING POWER TO BATTERY INCORPORATED IN TOOLHOLDER
Document Type and Number:
WIPO Patent Application WO/2023/234169
Kind Code:
A1
Abstract:
[Problem] To provide a method and a device for feeding power to a battery incorporated in a toolholder, with which it is possible to reasonably improve the problem of power feeding to a battery incorporated in a toolholder. [Solution] The present invention comprises: a power transmission unit 10 which is provided so as to be separated from a toolholder; and a power reception unit 20 which is provided to the toolholder. The power transmission unit generates an alternating magnetic field. The power reception unit converts the alternating magnetic field into electric current by means of a power reception coil, and feeds power to a battery in a non-contact manner. The power transmission unit is provided so as to be capable of facing a sensing toolholder 30 that is mounted on a main spindle, and performs power feeding to the battery by exciting the power reception coil of the sensing toolholder mounted on the main spindle with the alternating magnetic field. A workpiece to be machined by a tool is of a conductive material, and a removal device 50 for machining chips from the workpiece is provided between the power transmission unit and the power reception unit.
