Abstract

The invention discloses a clamp-type inertial piezoelectric linear motor, which comprises a stator fixed frame and an output rod. The stator fixed frame is a hollow structure. An upper clamp block and a lower clamp block are arranged horizontally at the ends respectively, and a wedge is placed between the two lower clamp blocks; a ring-shaped laminated piezoelectric ceramic is arranged in the fixed frame of the stator, and the upper end of the ring-shaped laminated piezoelectric ceramic is against Lean against the inner surface of the upper end of the stator fixed frame, the lower end of the annular laminated piezoelectric ceramics is against the upper end of the wedge, the output rod passes through the stator fixed frame, annular laminated piezoelectric ceramics, and the wedge in turn, and the lower end of the output rod extends Wedge out. The stator in the inertial piezoelectric linear motor of the present invention adopts a clamp-type structure, and the left and right levers can be adjusted to meet different precision requirements; at the same time, the clamp-type structure can achieve high precision by increasing the clamp and output during work. The positive pressure and friction between the rods increase the output thrust.

Description

technical field [0001] The invention belongs to the technical field of piezoelectric precision actuation, and in particular relates to a clamp-type inertial piezoelectric linear motor. Background technique [0002] Piezoelectric linear motors have the characteristics of high positioning accuracy, fast response speed, flexible design, and immunity to electromagnetic interference. They have broad application prospects in emerging cutting-edge technology fields. In recent years, piezoelectric linear motors have been developed rapidly under the extensive attention of researchers from many countries. Classified according to the principle, the piezoelectric motor can be divided into resonant and non-resonant motors. In the resonant motor, the vibrating body is driven by a signal in the ultrasonic frequency band to generate micro-amplitude vibration through modal coupling, and the dynamic force is driven by friction. The motor produces a large-stroke motion, and the use of the cou...
