Abstract

The invention discloses a circuit compensation network of a non-contact power supply ultrasonic vibration system for realizing maximum transmission efficiency. The circuit compensation network comprises a primary compensation network and a secondary compensation network. The primary compensation network is connected between an ultrasonic power supply and a primary coil of a non-contact electromagnetic coupler to compensate reactive power of the system and make voltage and current output by the power supply in phase. The secondary compensation network is connected between a secondary coil of the non-contact electromagnetic coupler and an ultrasonic vibrator to realize highest-efficiency energy transmission by optimizing the parameters of a secondary compensation element(s), wherein the compensation element(s) is / are an inductor or / and a capacitor. The circuit compensation network of the invention can be applied to rotary ultrasonic machining, ultrasonic welding, and other occasions in which a non-contact electromagnetic coupler needs to be adopted to supply power to an ultrasonic vibrator. Highest-efficiency energy transmission is realized by optimizing the parameters of the secondary compensation element(s).

Description

technical field

[0001] The invention relates to a technology of using a non-contact rotating electromagnetic coupler to supply power to an ultrasonic transducer, in particular to a circuit compensation method for realizing the maximum transmission efficiency of the non-contact energy transmission system. Background technique

[0002] Rotary ultrasonic machining uses consolidated diamond tools (electroplated or sintered diamond tools) for ultrasonic vibration and high-speed rotation at the same time. Widely used in the processing of hard and brittle materials such as engineering ceramics, composite materials, titanium alloys, etc., rotary ultrasonic machining can effectively improve material removal rate, improve workpiece surface quality and prolong tool life. Traditional rotary ultrasonic machine tools mostly use the power supply method of brush slip ring. This contact power supply method is prone to sparks and wear, and cannot be used in inflammable and explosive harsh en...
