A unidirectional ultrasonic vibration platform with adjustable clamps and its operating method

Abstract

The invention discloses a one-way ultrasonic vibration platform with adjustable clamps and an operation method thereof. A group of adjustable clamps are respectively fixed on the upper and lower surfaces of the two-dimensional porous vibration platform, and the ultrasonic transducer is connected to the two-dimensional porous ultrasonic vibration platform. A side center position. The adjustable fixture restricts 5 degrees of freedom of the part, and the clamping force is parallel to the direction of ultrasonic vibration; there are symmetrical and evenly distributed threaded holes and through holes on the two-dimensional porous ultrasonic vibration platform, which are used to isolate lateral vibration and increase the amplitude of longitudinal vibration. There are uniformly distributed through holes for controlling the vibration mode and reducing the volume of the device; the ultrasonic transducer drives the two-dimensional porous ultrasonic vibration platform to form a coupled vibration mode of longitudinal full wave and transverse half wave, and the coupled vibration forms a single vibration mode in the center of the platform. For longitudinal vibration, the area of ​​the central longitudinal vibration area is enlarged through coupling vibration. The invention realizes reliable positioning and clamping of parts with various sizes in ultrasonic machining through adjustable clamps. A family of similar parts can be processed ultrasonically.
