Hollow Water Outlet Ultrasonic Electric Spindle

Abstract

The invention discloses an ultrasonic electric spindle with a hollow water-discharge structure. The ultrasonic electric spindle comprises a spindle shell, a spindle rotor, a hollow water-discharge rotary connector, a wireless electricity energy transmission module, a squirrel-cage type motor, a hollow water-discharge connection pipe and a hollow water-discharge energy converter; the spindle rotor is provided with a water conveying channel; and the hollow water-discharge energy converter is arranged at the head of the spindle shell and is connected with the water conveying channel through the hollow water-discharge connection pipe. According to the ultrasonic electric spindle with the hollow water-discharge structure, the structural design is ingenious and reasonable; water passes the hollow water-discharge rotary connector, enters the spindle rotor and is sprayed out from a tool head of the hollow water-discharge energy converter; the cooling effect is good, cutting heat is effectively improved, and the cutter service life is prolonged; meanwhile, scraps in a deep hole can be discharged out through a water current sequentially, and accordingly the problem of difficult scrap discharging during deep hole machining is solved; and thus, the advantage on the deep hole machining aspect is effectively improved, the machining efficiency, effect, precision and quality, the cutter service life and the like are greatly improved, the machining effect is good, the working stability is high, and wide popularization is facilitated.

Description

technical field [0001] The invention relates to the technical field of ultrasonic electric spindles, in particular to a hollow water outlet ultrasonic electric spindle. Background technique [0002] In recent years, some new hard and brittle composite materials such as C / SiC and C / C have been used more and more in aerospace, automobile, energy and other fields, but these hard and brittle composite materials are not as easy to process as traditional materials. Traditional mechanical processing methods are prone to defects such as fiber tearing, delamination, and burrs, and the tool wear is severe and the efficiency is low. Ultrasonic vibration processing technology is considered to be one of the most suitable methods for processing hard and brittle composite materials. It is in the traditional Based on the relative movement of the workpiece and the tool in machining, ultrasonic vibration is applied to the workpiece or the tool to obtain better processing performance.
