Abstract

The invention relates to a double-spiral-groove combined type single-excitation three-dimensional curved surface ultrasonic-assisted turning device and belongs to the field of compound ultrasonic vibration cutting machining. The double-spiral-groove combined type single-excitation three-dimensional curved surface ultrasonic-assisted turning device comprises an ultrasonic excitation device, a double-spiral-groove combined type pressing twisting device and a fixed frame. Through combination of the ultrasonic excitation device and the double-spiral-groove combined pressing twisting device, underultrasonic high-frequency vibration excitation, the double-spiral-groove combined type pressing twisting device is twisted in the horizontal direction and meanwhile deforms in the vertical direction,a turning tool vibrates up and down to a certain extent in the vertical plane in the axial direction while being driven to make arc-shaped rotation movement in the horizontal plane, and one-dimensional ultrasonic vibration generated by the ultrasonic excitation device in a single-excitation form is converted into three-dimensional curved surface type composite ultrasonic vibration for ultrasonic-assisted turning machining. By adjusting the elements such as the amplitude and frequency of the ultrasonic excitation device, the number of spiral grooves and the grooving width, and different tracksof three-dimensional curved surface movement of the turning tool are changed so as to adapt to different machining conditions and meet different requirements.

Description

technical field [0001] The invention belongs to the technical field of composite ultrasonic vibration cutting and processing, and in particular relates to a double helical groove combined single excitation three-dimensional curved surface ultrasonic assisted turning device. Background technique [0002] With the rapid development of the machinery industry and the acceleration of product upgrading, the industrial upgrading of the equipment manufacturing industry is imminent, and the requirements for the processing accuracy and processing efficiency of mechanical parts are getting higher and higher. Especially in recent years, with the rapid development of aerospace, semiconductor and electronic industries, and the wide application of crystalline silicon, optical glass, engineering glass and other materials, the processing technology for these hard and brittle difficult-to-machine materials has been stagnant, which is serious. Influenced the further popularization and applicat...
