Precise wireless ultrasonic coupler with high adaptability

Abstract

The precise wireless ultrasonic coupler is connected with an ultrasonic knife handle and a machine tool spindle and comprises a magnetic core seat, a magnetic core, a coil, a hanging lug and a hoop, a knife handle hole is formed in the middle of the magnetic core seat, the ultrasonic knife handle is sleeved with the knife handle hole, a first U-shaped ring groove is formed in one side of the magnetic core seat and located on the outer side of the knife handle hole, the magnetic core is annular, and the coil is arranged in the magnetic core seat. The magnetic core seat is connected into the first U-shaped annular groove, a second U-shaped annular groove is formed in one side of the magnetic core seat, the coil is annular and connected into the second U-shaped annular groove, the two hanging lugs are connected to the magnetic core seat, located on the outer side of the cutter handle hole and in contact with the machine tool spindle, and the hoop is located on the outer sides of the two hanging lugs, arranged on the machine tool spindle in a sleeving mode and used for clamping the hanging lugs to the machine tool spindle. According to the precise wireless ultrasonic coupler with the high adaptability, stable connection between the wireless coupler and the machine tool spindle and between the wireless coupler and the ultrasonic cutter handle can be effectively guaranteed, installation is convenient, the ultrasonic coupling performance is guaranteed, and the stability of ultrasonic machining is improved.

Description

technical field [0001] The invention relates to the field of wireless ultrasonic couplers, in particular to a precise wireless ultrasonic coupler with high adaptability. Background technique [0002] Ultrasonic tool holders are widely used in the processing of hard and brittle phase materials and sticky materials. During the working process of the ultrasonic tool holder, it needs to be powered by the ultrasonic power supply, and the function of the wireless ultrasonic coupler is to be installed at the lower end of the machine tool spindle to realize the wireless connection between the ultrasonic tool holder and the ultrasonic power supply, and to provide energy to the ultrasonic tool holder. The connection between the existing wireless coupler and the spindle of the machine tool and the ultrasonic tool holder is not stable enough, the installation is difficult, and the ultrasonic coupling performance is unstable, which seriously affects the stability of ultrasonic machining....
