Embodiment Construction

[0054] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0055] like Figure 1 to Figure 3 As shown, a single-blade lateral milling method based on torsional ultrasonic vibration adopts a milling method combining single-blade side milling and ultrasonic machining. Device 3, support sleeve 4, horn 5 and single-edged milling cutter 7, etc. The transducer 3 connected to the horn 5 is located inside the support sleeve 4, avoiding direct contact with the external environment and ensuring safe operation; The generator 2 is connected to realize the ultrasonic signal input in the rotating state of the single-edged milling cutter.

[0056] The end of the horn 5 is equipped with a single-edged milling cutter 7, the single-edged milling cutter 7 is composed of a disc 701 and a single cutter head 702 fixed on the circumference of the disc, the single-edged milling cutter 7 is connected with the horn 5 through a tapered thread , The...

Abstract

The invention relates to a single-blade lateral milling method based on torsional ultrasonic vibration. The single-blade lateral milling method is characterized in that an ultrasound single-blade lateral milling device is driven by a machine tool spindle to rotate, a workpiece is fed on a machine tool workbench, normal contact between a tool bit and a machining face is always maintained during machining, the turning radius of a tool bit and workpiece contact point is smaller than the curvature radius of the contact point on the workpiece, the vibration direction is the tangential direction ofrotation of a single-blade milling cutter, and a single-blade lateral milling mode under torsional ultrasonic vibration is realized. The single-blade lateral milling method has the advantages that themethod is novel, the structure is unique, the process is practical, and reliability is high; the ultrasound single-blade lateral milling device is simplified in structure, downsized and convenient tomount; single-blade milling impact is improved, the method is adapted to milling of narrow and deep structures, frequency variation of a sound and vibration system is overcome, and heat radiation ofthe sound and vibration system is omitted; the problem of milling difficulty of high-hardness high-precision complex undercut hook faces and high-hardness variable-pitch spiral grooves is solved undercommon technological conditions, and the application prospect is abroad.

Description

technical field [0001] The invention belongs to the new technology field of ultrasonic machining, and specifically relates to a single-blade side milling method based on torsional ultrasonic vibration, which is a single-blade side milling mode integrating the dual advantages of ultrasonic machining and single-blade milling. Background technique [0002] Due to the structure of the parts or the requirements of the process, etc., it is often necessary to use the single-edge lateral milling method, especially when the three-axis continuous milling of the deep undercut part of the integral part. [0003] Different from general milling, single-blade milling generally uses non-standard tools instead of standard milling cutters or forming knives. When it comes to single-blade lateral milling, it is usually self-made tools, such as turning tools (square tool holders). On a cylindrical tool shank with a square hole (the turning tool is perpendicular to the cylindrical shank, and the ...
