One-way ultrasonic vibration platform with adjustable clamps and operation method for one-way ultrasonic vibration platform

Abstract

The invention discloses a one-way ultrasonic vibration platform with adjustable clamps and an operation method for the one-way ultrasonic vibration platform. According to the one-way ultrasonic vibration platform, one group of adjustable clamps is fixed to each of the upper surface and the lower surface of a two-dimensional porous vibration platform body, and an ultrasonic transducer is connected to the center position of one side surface of the two-dimensional porous ultrasonic vibration platform body; the adjustable clamps limit five degrees of freedom of parts, and the clamping force is parallel to the ultrasonic vibration direction; threaded holes and through holes I are symmetrically and evenly distributed in the two-dimensional porous ultrasonic vibration platform body and are used for isolating transverse vibration and increasing the longitudinal vibration amplitude, and through holes II are evenly distributed in the side surface and are used for controlling the vibration mode and decreasing the size of the device; and the ultrasonic transducer drives the two-dimensional porous ultrasonic vibration platform body to form a coupled vibration mode of longitudinal full waves and transverse half waves, in addition, coupled vibration forms single longitudinal vibration in the center of the platform body, and the area of a central longitudinal vibration area is enlarged through the coupled vibration. The one-way ultrasonic vibration platform and the operation method thereof have the advantages that reliable positioning and clamping of the parts of various sizes in ultrasonic machining are realized through the adjustable clamps; and ultrasonic-assisted machining of the similar parts of the same family can be realized.
