Abstract

The invention discloses a device for broaching a workpiece with the help of additional ultrasonic vibration. In the prior art, an existing device is complex in structure and not high in accuracy. The device comprises an ultrasonic generator, an ultrasonic energy exchanger, a working table, an eddy current sensor, a sensor support, an ultrasonic amplitude-change pole, a front amplifier, a conversion plate, a data acquisition card and an industrial personal computer. During broaching, a tool and the workpiece make contact with each other and are separated from each other periodically at a high frequency; it is quite different from that the tool and the workpiece make contact with each other all the time during normal broaching. During ultrasonic vibration broaching, the effects of improving workpiece machining quality, prolonging the service life of a broach, improving broaching surface smoothness and reducing built-up edges on the broach can be achieved according to the characteristic that the tool and the workpiece can be separated from each other.

Description

technical field [0001] The invention relates to a method and a device for an ultrasonic-assisted broaching process, in particular to a broaching device for adding ultrasonic vibration to a workpiece. Background technique [0002] Ultrasonic machining is a special processing that uses ultrasonic frequency to vibrate with a small amplitude, and through the hammering action of the abrasive free in the liquid between it and the workpiece on the surface to be processed, the surface of the workpiece material is gradually broken. Broaching can obtain high dimensional accuracy and small surface roughness, high productivity, and is suitable for mass production in batches. In the actual broaching production, the broaching load of the broach will change with the progress of the production, the cutting resistance is large, the quality of the processed surface is abnormal and the processing size is easy to fluctuate, which affects the processing accuracy, processing efficiency and proces...
