Abstract

The invention discloses a wireless power supply device for an intelligent knife handle system, and belongs to the field of non-contact electric energy transmission; the wireless power supply device comprises an electric energy transmitting unit and an electric energy receiving unit. The electric energy transmitting unit comprises a supporting protection ring, a transmitting coil arranged on the lower surface of the supporting protecting ring, and a transmitting unit circuit arranged in the supporting protecting ring, and the unit is responsible for converting the power-frequency alternating current into high-frequency alternating current and transmitting the high-frequency alternating current through the transmitting coil; the electric energy receiving unit comprises an intelligent knife handle ring, a receiving coil arranged on the upper surface of the intelligent knife handle ring and a receiving unit circuit arranged in the intelligent knife handle ring, and the unit is responsiblefor converting the high-frequency alternating current into low-voltage direct current capable of being used for charging the intelligent knife handle of the lithium battery through rectification filtering, and meanwhile, the voltage signals output by the electric energy receiving unit are transmitted to the electric energy transmitting unit through Bluetooth to form feedback adjustment. Accordingto the wireless power supply device, the cruising problem of the intelligent knife handle system is effectively solved, and the processing production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of non-contact power transmission, in particular to a wireless power supply device for an intelligent tool handle system. Background technique [0002] In the field of milling process monitoring, the traditional method is to use various sensing elements such as dynamometers, acceleration sensors or acoustic emission sensors to be fixed on the machine tool or workpiece to collect signals related to the processing process, and then monitor the processing process. The method has the disadvantages of cumbersome installation, great influence on the installation location, and poor repeatability. At present, many scholars are studying the integration of multiple sensors into the position of the tool holder to form a set of intelligent tool holder system to monitor the milling process. This method is easy to use, can collect multiple signals at the same time and is not affected by the size of the workpiece, and is s...
