Abstract
The utility model relates to an asymmetric clamping piezoelectric inertial driver with a ploughing effect. The driver comprises a guide rail, a driver pedestal, a support plate, a sliding block, a piezoelectric bimorph oscillator, and an end quality block. An excitation signal of the driver is a symmetrical waveform signal. A drive element is the piezoelectric bimorph oscillator. The piezoelectric bimorph oscillator is clamped asymmetrically to generate inertial impact forces in positive and negative directions, wherein the inertial impact forces have different magnitudes. The driver pedestal is provided with a wedge-shaped frictional foot with the ploughing effect, thereby allowing the driver to move in positive and negative directions on the guide rail to generate frictional forces with different magnitudes. Therefore, the small frictional force can be generated between the driver and the guide rail when the driver moves in the positive direction and withstands a great inertial impact force. And the great frictional force can be generated between the driver and the guide rail when the driver moves in the negative direction and withstands a small inertial impact force. The drive can only move towards the positive direction. The driver provided by the utility model is simple in circuit, high in positioning accuracy, large in stroke, and the like.
