Abstract

The invention relates to a one-dimensional micro-displacement table. The one-dimensional micro-displacement table comprises a bottom frame, wherein a movable table is arranged in the bottom frame; a drive device is arranged between the movable table and the bottom frame; the drive device comprises two groups of drivers; each group of drivers comprises two rhombic ceramic drivers which are connected in series; a micro-displacement sensor is further arranged in the bottom frame; each rhombic ceramic driver comprises two first connecting parts which are oppositely arranged and two second connecting parts which are oppositely arranged, and connecting arms are arranged between the first connecting parts and the second connecting parts; and a piezoelectric ceramic driver is arranged between the two second connecting parts, the piezoelectric ceramic driver comprises a mounting box, and piezoelectric ceramic, a first drive arm and a second drive arm are arranged in the mounting box. The one-dimensional micro-displacement table is relatively great in drive force and output range.

Description

technical field [0001] The invention relates to a displacement platform, in particular to a one-dimensional micro displacement platform. Background technique [0002] Piezoelectric ceramics are information functional ceramic materials that can convert mechanical energy and electrical energy into each other. In addition to piezoelectricity, piezoelectric ceramics also have dielectric properties, elasticity, etc., and have been widely used in medical imaging, acoustic sensors, acoustic transducers, ultrasonic motors, etc. In addition, people can also use the inverse piezoelectric effect to make it into a piezoelectric driver to achieve micro-displacement driving of objects. Existing devices for realizing micro-displacement driving include one-dimensional micro-displacement stages. The current micro-displacement stages generally drive the movement of the stage through a piezoelectric ceramic driver. The driving force is small, the driving capacity is limited, and the micro-dis...
