Ultrasonic knife handle with electrodes

Abstract

The invention discloses an ultrasonic knife handle with electrodes. The ultrasonic knife handle comprises a knife handle body and a transducer, the outer side of the knife handle body is provided witha conductive sheet and an insulating sleeve, the conductive sheet and the insulating sleeve are integrally designed with the knife handle body and fixed on the outer tapered end face of the knife handle body, one end of the transducer is arranged in the knife handle body, and the transducer comprises an amplitude-change pole, piezoelectric ceramic, a transducer pressing block and a pressing screw; by adopting interference fit and an extrusion mode, the transducer is integrally connected with the knife handle body, the pressing screw is sequentially connected with a transducer pressing cover,the piezoelectric ceramic and the amplitude-change pole and is tightly connected with a amplitude-change pole pressing nut, and the front end of the amplitude-change pole is provided with an inner tapered hole used for installing a standard cutting tool clamping head. The knife handle can achieve electric leakage protection, dust proofing and water proofing; in additional, the machining efficiencycan be improved, the cutting force is reduced, and the surface quality after machining is improved.

Description

technical field [0001] The invention relates to the field of machine-ultrasonic-assisted grinding, in particular to an ultrasonic knife handle. Background technique [0002] Ultrasonic machining is one of the most suitable processing methods for hard and brittle materials. It removes the processed material on the workpiece by means of ultrasonic high-frequency and small-amplitude vibration on the basis of ordinary grinding, and passes between it and the workpiece. Abrasives dissociated in the cutting fluid hammer the surface to be machined, and the surface of the workpiece material is gradually broken into special processing. Ultrasonic machining can strengthen and improve the effect of ordinary machining. It not only retains the characteristics of ordinary machining, but also can greatly improve the processing efficiency (processing efficiency can reach 3-5 times that of ordinary grinding), reduce the deformation of cutting, It reduces the cutting force and can effectively...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to overcome the problems existing in the existing ultrasonic knife handle, and provide an ultrasonic knife handle with electrodes. The knife handle is different from the ordinary standard knife handle, but the conductive copper The conductive copper sheet is used to conduct the current on the spindle of the CNC machine tool to the transducer of the tool handle, so as to realize the high-frequency and small-amplitude vibration of the tool at the front end of the tool handle. The insulating sleeve is used to connect the current on the spindle of the CNC machine tool with the The shell of the handle is separated, so as to solve the problems of electric leakage, easy pollution of dust and non-waterproof in the prior art
