A non-contact ultrasonic processing device and its processing technology

Abstract

The invention discloses a non-contact ultrasonic processing device and its processing technology, which include a tool handle assembly, a transducer assembly, and a non-contact energy transmission device. The tool handle assembly includes an upper shaft connected to the main shaft of a machine tool and a hollow lower Shaft, the end of the lower shaft is provided with an inner cone surface, and the upper part of the inner cone surface is provided with an inwardly protruding inner end surface. The small end of the inner cone surface points to one side of the inner end surface of the lower part of the handle. The transducer assembly includes the upper piezoelectric ceramics The stack and the electrode piece, the nodal flange in the middle, the lower horn and the tool connection structure at the end of the horn, the outer circle of the nodal flange is processed into an outer cone, and the small end of the cone points to the piezoelectric ceramic stack On one side, the inner tapered surface of the lower shaft of the tool holder assembly cooperates with the outer tapered surface of the nodal flange, and a gasket is arranged between the inner end surface of the lower shaft of the tool holder assembly and the top end of the outer tapered surface of the nodal flange. The invention adopts taper surface positioning, which improves the coaxiality accuracy of the installation of the transducer and the tool handle, and uses the washer to compensate the flatness error of the flange end surface.

Description

technical field [0001] The invention relates to the technical field of ultrasonic processing equipment, in particular to a non-contact ultrasonic processing device and a processing technology thereof. Background technique [0002] A common ultrasonic machining device connects the transducer assembly to the tool holder assembly through a flange located at the node of the standing wave. Since the transducer assembly rotates with the tool handle assembly, it has coaxial precision requirements with the tool handle assembly. If the coaxiality error is too large, the dynamic imbalance generated by the ultrasonic machining device will be aggravated. This problem has a greater impact when working at high speeds and cannot be ignored. Generally, the side of the flange of the transducer is a cylindrical surface, which is used for positioning during assembly, but the processing of the cylindrical surface for precise positioning is difficult, and the assembly coaxiality error is large...
