Abstract: A machine tool of high-frequency vibration is provided. A main shaft structure of the machine tool comprises a rotating shaft, the end of which is provided with a tool holder chuck for fixing a tool holder; the upper portion of which is provided with a rotating coil portion; the main shaft structure is correspondingly provided with a stationary coil portion; and the tool holder is provided with a high-frequency vibration module. By non-contact coils, an external electric power/signal can be transmitted into the high-frequency vibration module to avoid a wear phenomenon in a contact-rotating electrode. Because the inductive coil is arranged outside of the tool holder, the manufacturing cost of the tool holder is reduced, and the convenience of changing the tool holder is increased. Moreover, the machining stability and efficiency of the tool holder are improved by a control method of sensing/feedback signals with wireless transmission.

Abstract: 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.

Abstract translation: 提供高频振动的机床。 机床的主轴结构包括旋转轴，其端部设置有用于固定工具架的工具夹头卡盘; 其上部设置有旋转线圈部分; 主轴结构相应地设置有固定线圈部分; 并且工具架设有高频振动模块。 通过非接触线圈，外部电力/信号可以传输到高频振动模块中，以避免接触旋转电极中的磨损现象。 由于感应线圈设置在刀夹的外侧，因此刀架的制造成本降低，并且提高了刀架的变更的便利性。 此外，通过无线传输的感测/反馈信号的控制方法，提高了刀架的加工稳定性和效率。
