Ultrasonic spindle, ultrasonic tool holder and ultrasonic processing equipment

Abstract

The present invention relates to the technical field of ultrasonic processing, in particular to an ultrasonic spindle, an ultrasonic tool handle and ultrasonic processing equipment, including a spindle housing; There are installation holes; the launching frame is arranged on the front side of the spindle housing. The launching frame includes a launching part, which is in the shape of a non-full circle around the outer circumference of the rotating shaft assembly. An annular first accommodation tank; an ultrasonic wireless transmitting unit, which is arranged in the first accommodation tank, and the ultrasonic wireless transmitting unit includes a transmitting coil and a transmitting ferrite. By replacing the traditional full-ring wireless transmitting device with a non-full-circular ultrasonic wireless transmitting unit, after the ultrasonic tool handle is installed on the ultrasonic spindle, it is possible to leave a space for the tool holder on the tool holder body , so that the tool magazine can be used for automatic tool change, and the versatility 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...

Problems solved by technology

[0004] At present, the main difference between the structure of the ultrasonic spindle and the structure of the ordinary machine tool spindle is that an ultrasonic wireless transmitting device is installed on the front side of the ordinary machine tool spindle, and the ultrasonic wireless transmitting component is a full-ring structure. , the ultrasonic wireless transmitting device will interfere with the original tool magazine, resulting in the inability to change the tool automatically. To realize the automatic tool change without interference between the ordinary tool holder and the ultrasonic tool holder on the tool magazine, it is necessary to customize a non-universal tool magazine , leading to the inability to realize the versatility of the tool magazine of the equipment, thus greatly increasing the cost
