Embodiment Construction

[0021] As shown in Figures 1 and 2, the double-knife reverse-feed ultrasonic torsional vibration turning and milling system uses two sets of ultrasonic torsional vibration turning and milling devices in the turning and milling system, which are arranged along both sides of the radial direction of the workpiece. The radial force in the center can be balanced, which can completely eliminate the bending deformation caused by the radial force; the reverse feed is supplemented by an elastic tip, which eliminates the phenomenon of pressure instability and cutting temperature rise caused by the processing of slender shafts. The problem of bending deformation caused by the elongation of the slender shaft.

[0022] The ultrasonic torsional vibration turning and milling device has an ultrasonic generator 7, a torsional vibration sandwich piezoelectric transducer 8, a torsional vibration horn 9, a flange 10, a milling cutter disc 11, cutter teeth 12, a frame, and a torsional vibration Th...

Abstract

The present invention discloses one kind of ultrasonic torsional vibration turning-milling system and method. In the turning-milling process, the resultant motion of the rotation of the milling cutter, the rotation of the workpiece, the axial feeding of the milling cutter shaft, the radial feeding of the milling cutter and the ultrasonic torsional vibration of the milling cutter is adopted to complete the cutting of the workpiece. The ultrasonic torsional vibration of the milling cutter is generated with two sets of ultrasonic torsional vibration devices arranged radially along the workpiece. The present invention has the advantages of eliminating the bending deformation the radial force generates, eliminating the bending deformation caused by elongation of slender shaft, high machining precision, etc.

Description

technical field [0001] The invention relates to a turning method, in particular to a double-knife reverse-feed ultrasonic torsional vibration turning and milling system and a method thereof. Background technique [0002] Variable cross-section slender rods refer to shaft parts with a maximum diameter of less than 50mm, an aspect ratio of 12-100, and a variable cross-section. It has a wide range of uses in the fields of machinery manufacturing, defense industry and acoustics. For example, the control rod is a slender rod with variable cross-section in the hydraulic recoil machine. It cooperates with the fixed-diameter ring to form a variable flow hole to ensure the movement of the recoil when the artillery fires. Therefore, the control rod is an important part of modern artillery products, and artillery designers have put forward strict requirements on its dimensional accuracy, shape accuracy and surface quality. In ultrasonic processing equipment, various forms of horns and...
