ELECTRICITY SUPPLY TOOL HOLDER FOR MACHINING CENTER

摘要

An electricity supply tool holder for a machining center is provided, and has: a holder body, a stationary coil portion, a rotating coil portion, a lateral fixing portion, and an electrical machinery. The stationary coil portion is provided with a primary coil therein; the rotating coil portion is correspondingly provided with a secondary coil therein; and the lateral fixing portion is fixed on a side of the stationary coil portion used for removably combining with a machining center. When the tool holder is rotated, an external electric power/signal can be transmitted through the lateral fixing portion to the primary coil, then inducing the secondary coil, then the electric power/signal is transmitted to the electrical machinery. Additionally, the lateral fixing portion can be switched into a locked position to temporarily limit rotation, so that it can be used in a machining center of an Automatic Tool Changing (ATC) system.

主权项

1. An electricity supply tool holder for a machining center, used in the machining center having a rotating shaft, and comprising:
a holder body formed as a column and including a holder shank disposed on an upper end thereof and a tool chuck disposed on a lower end thereof, wherein the holder shank is used for removably combining with a holder shank chuck of an end of the rotating shaft of the machining center; and the tool chuck is used for clamping and downwardly fixing a cutting tool; a stationary coil portion coaxially and rotatably disposed on the holder body and being provided with at least one primary coil therein; a rotating coil portion coaxially and fixedly disposed on the holder body and being provided with at least one secondary coil therein, wherein the secondary coil corresponds to the primary coil; a lateral fixing portion fixed on a side of the stationary coil portion and used for removably combining with a fixing location of the machining center, wherein the lateral fixing portion comprises at least one set of input electrode portions, one end of which is removably and electrically connected to an electric source of the machining center, and the other end of which is electrically connected to the primary coil of the stationary coil portion by at least one set of first electric wires; and an electrical machinery disposed inside the holder body and electrically connected to the secondary coil of the rotating coil portion by at least one set of second electric wires; wherein when the electricity supply tool holder is mounted on the holder shank chuck of the machining center and starts to be rotated, the machining center transmits an electric power/signal to the set of first electric wires, then to the primary coil of the stationary coil portion, and the secondary coil of the rotating coil portion is induced to generate an electric power/signal, then the electric power/signal is transmitted to operate the electrical machinery.
