Two-dimensional ultrasonic vibration angle-adjustable workpiece clamping system

A two-dimensional ultrasonic vibration angle-adjustable workpiece clamping system comprises a support, an angle adjustment driving mechanism, a fixed cylinder, a rotating cylinder, a precise numerical control rotary table, a transducer and an amplitude-change pole assembly. Ultrasonic vibration is added to the workpiece, grinding force and grinding temperature are effectively reduced, the grinding effect is improved, meanwhile, the inclination angle of the center line of the gear workpiece is adjusted, namely, the included angle between the center line of the gear workpiece and the rotation center line of a gear is adjusted, and therefore the grinding angle and range can be enlarged, and the grinding device is suitable for wider grinding operation. 二维超声振动角度可调式工件夹持系统，包括支架、角度调节驱动机构、固定筒、旋转筒、精密数控转台、换能器和变幅杆组件；本实用新型采用对工件进行增加超声振动，有效的降低磨削力、磨削温度，提高磨削效果，同时对齿轮工件的中心线的倾角进行调节，即调节齿轮工件的中心线与齿轮回转中心线的夹角，这样可扩大磨削的角度和范围，适应更广泛的磨削作业。
