Problems solved by technology

[0003] At present, the research on ultrasonic vibration-assisted milling and grinding is mainly based on the one-dimensional ultrasonic vibration of the spindle. This method requires a large change to the spindle, which affects the inherent high machining accuracy of the machine tool spindle, and the ultrasonic amplitude generated is relatively small. Small
The research on 2D ultrasonic vibration assisted machining is still in the exploratory stage, and there are still many technical problems to be solved in applying 2D ultrasonic vibration to the spindle.

Abstract

The invention belongs to the field of ultrasonic processing technology in special processing technology. It discloses a single-excitation two-dimensional ultrasonic vibration-assisted micro-machining platform, which includes a right-angled bottom plate, a linear guide rail, upper and lower vibration blocks, a support plate, and a horn. Energizer, ultrasonic generator. The upper and lower vibrating blocks are arranged perpendicularly to each other along the feed and side cutting directions respectively. The lower vibrating block and the bottom plate, and the lower vibrating block and the upper vibrating block are connected through linear guide rails. The workpiece is fixed on the upper vibrating block through a threaded connection. piece. The vibration block and the horn, and the horn and the transducer are all connected by double-headed studs. Two sets of horns are fixed on the base plate through the support plate at the node. The two sets of transducers are connected to the same ultrasonic generator through wires. They output two ultrasonic signals at the same time and have a phase difference adjustment function. By adjusting the ultrasonic generator The amplitude and phase difference of the output signal are coupled to different elliptical vibration trajectories according to actual needs to achieve high-efficiency and high-precision processing.
