Abstract

The invention relates to the technical field of ultrasonic machining, in particular to an ultrasonic main shaft, an ultrasonic knife handle and ultrasonic machining equipment. The ultrasonic main shaft comprises a main shaft shell,a rotating shaft assembly, a launching frame and an ultrasonic wireless transmitting unit; the rotating shaft assembly is rotatably arranged in the main shaft shell in apenetrating mode, and a mounting hole is formed in the front end face of the rotating shaft assembly; the launching frame is arranged on the front side of the main shaft shell and comprises a launching part, the launching part is in a non-full-circular-ring shape arranged around the periphery of the rotating shaft assembly, and a first accommodating groove in a non-full-circular-ring shape is formed in the inner side face of the launching part; and the ultrasonic wireless transmitting unit is arranged in the first accommodating groove, and comprises a transmitting coil and a transmitting ferrite. According to the ultrasonic main shaft, by replacing a traditional full-ring type wireless transmitting device with the non-full-ring type ultrasonic wireless transmitting unit, after the ultrasonic knife handle is installed on the ultrasonic main shaft in a matched mode, an avoiding space can be reserved at the knife clamping position of the knife handle body, and therefore the tool magazinecan conduct automatic tool changing, and the universality of the equipment tool magazine can be improved.

Description

technical field [0001] The invention relates to the technical field of ultrasonic processing, in particular to an ultrasonic spindle, an ultrasonic tool handle and ultrasonic processing equipment. Background technique [0002] Ultrasonic machining equipment introduces high-frequency vibration into the rotary motion of the tool, which can not only improve the surface roughness of the machined surface, improve the machining accuracy, but also reduce the cutting resistance and improve the service life of the tool, so it is widely used. [0003] The existing ultrasonic spindle includes fixed parts, rotating parts, bearings and ultrasonic transmission devices. Among them, the fixed parts include related parts such as the main shaft housing and the front end cover. Rotating parts include related parts such as rotating shafts. The ultrasonic transmission device may be an ultrasonic wireless transmitting unit or an ultrasonic wired transmission device. [0004] At present, the ma...
