Dynamic balance ultrasonic cutterhead

Abstract

The invention relates to the technical field of machining and particularly relates to a dynamic balance ultrasonic cutterhead. The dynamic balance ultrasonic cutterhead comprises a knife handle, a cutterhead, a dynamic balance ring, an ultrasonic transducer and wireless transmission transmitting and receiving devices; the knife handle comprises a knife handle main body and an assembly joint; the dynamic balance ring is sleeved on the knife handle main body and is used for adjusting the center-of-gravity position of the whole cutterhead; an accommodating cavity is formed at one end, away from the assembly joint, of the knife handle main body; the ultrasonic transducer is positioned in the accommodating cavity; the wireless transmission transmitting device is positioned on the main shaft; the wireless transmission receiving device is sleeved on the knife handle main body and is connected with the ultrasonic transducer. According to the dynamic balance ultrasonic cutterhead provided by the invention, through the ultrasonic transducer arranged in the knife handle, the cutterhead generates high-frequency vibration so as to realize ultrasonic processing. Moreover, the dynamic balance ring adjusts the overall dynamic balance performance of the cutterhead component so as to reduce mechanical failure.

Description

technical field [0001] The present application relates to the technical field of machine tool processing, in particular to a dynamically balanced ultrasonic cutterhead. Background technique [0002] As the connection between the machine tool spindle and the cutting tool, the tool holder plays the role of rigidly connecting the machine tool spindle and the cutting tool; in order to adapt to the rotary ultrasonic machining, people integrate the vibration system into the tool holder to obtain an ultrasonic tool holder. [0003] However, the structure of the traditional ultrasonic tool holder integrated with the vibration system is not stable enough, and its horn is prone to tilt after collision, thereby increasing the circular runout of the horn and affecting the dynamic balance of the horn, resulting in low machining accuracy of the ultrasonic tool handle. Poor, short service life. [0004] TWM372763U discloses an ultrasonic vibration tool module, the first coil is fixed to t...
