Abstract

The invention discloses a non-contact power supply device for a smart cutter handle, and belongs to the field of rotation component power transmission, which is used for solving the problems that according to the existing cutter handle power supply mode, the power is low and cannot be adaptive to the high rotation speed, and a cutter is difficult to change. The non-contact power supply device comprises a transmitting terminal device and a receiving terminal device, wherein the receiving terminal device comprises a receiving terminal circuit, a receiving coil group and a receiving support; the receiving support sleeves on a cutter handle; the receiving coil group is arranged on the outer surface of the receiving support; the receiving terminal circuit is arranged in the receiving support; the transmitting terminal device comprises a transmitting terminal circuit, a transmitting coil group and a transmitting support; one side of the transmitting support is an arc surface; the transmitting coil group is fixed on the inner side of the arc surface of the transmitting support; the transmitting terminal circuit is arranged in the transmitting support; the transmitting coil group and the receiving coil group form a basic transmitting model; according to the basic transmitting model, the transmitting terminal circuit and the receiving terminal circuit, the magnetic resonance coupling energy transmission principle is adopted for supplying power for a sensor on the cutter handle. The non-contact power supply device for the smart cutter handle is used for supplying power for an intelligent cutter handle for cutting and machining.

Description

technical field [0001] The invention belongs to the field of power transmission of rotating components. Background technique [0002] The modernization of machinery manufacturing has put forward higher and higher requirements for the speed and precision of cutting processing. In order to effectively utilize the manufacturing capabilities of automated processing systems, it is particularly important to monitor the cutting process in real time. [0003] The traditional monitoring method is mainly to build a single-parameter or multi-parameter cutting state monitoring system by using a desktop dynamometer, an independent vibration sensor, and an acoustic emission sensor. Considering that this method is complicated to install, inconvenient to use, and easily affected by the shape and size of the workpiece, etc. Insufficient, some researchers and practitioners began to integrate one or more sensors into the CNC tool holder, thus forming a set of intelligent tool holder system for...
