Abstract

The invention discloses a stackable piezoelectric ceramic. The stackable piezoelectric ceramic comprises a micro-sealing box and a stackable piezoelectric ceramic body. The stackable piezoelectric ceramic body is located at the bottom of the inner side of the micro-sealing box, a sealing cover is arranged at the upper end of the micro-sealing box, conducting layers are symmetrically arranged on the two sides of the stackable piezoelectric ceramic, insulation ceramic pieces are arranged at the upper end and the lower end of the stackable piezoelectric ceramic body respectively, a plurality of piezoelectric ceramic pieces are arranged between the two insulation ceramic pieces, a connecting plate is arranged between every two piezoelectric ceramic pieces, glue grooves are formed in the upper ends and the lower ends of all the connecting plates respectively, a fixing plate is arranged between every two glue grooves, baffles are symmetrically arranged at the two ends of each connecting plate respectively, fixing blocks are fixedly connected to one sides of all the baffles, and annular buckles are arranged at one ends, far away from the fixing blocks, of all the columns. According to the stackable piezoelectric ceramic, finished piezoelectric ceramic pieces are stacked to form piezoelectric ceramics with the different sizes, different pieces of displacement are achieved, and the stackable piezoelectric ceramic is suitable for wide popularization.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a stacked piezoelectric ceramic. Background technique [0002] Piezoelectric ceramics is an information functional ceramic material that can convert mechanical energy and electrical energy into each other—piezoelectric effect. 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., piezoelectric ceramics use their materials under the action of mechanical stress to cause the relative displacement of the internal positive and negative charge centers to cause polarization, resulting in the appearance of bound charges of opposite signs on the surfaces of the materials, that is, pressure. It is made of electric effect and has sensitive characteristics. Piezoelectric ceramics are mainly used in the manufacture...

[0002] Piezoelectric ceramics is an information functional ceramic material that can convert mechanical energy and electrical energy into each other—piezoelectric effect. 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., piezoelectric ceramics use their materials under the action of mechanical stress to cause the relative displacement of the internal positive and negative charge centers to cause polarization, resulting in the appearance of bound charges of opposite signs on the surfaces of the materials, that is, pressure. It is made of electric effect and has sensitive characteristics. Piezoelectric ceramics are mainly used in the manufacture of ultrasonic transducers, underwater acoustic transducers, electroacoustic transducers, ceramic filters, ceramic transformers, ceramic frequency discriminators, high voltage generators, Infrared detectors, surface acoustic wave devices, electro-optical devices, ignition and detonation devices, and piezoelectric gyroscopes, etc., are not only used in high-tech fields, but also serve people in daily life, and at the same time, deep processing of piezoelectric ceramics is required , the existing piezoelectric ceramics have a single shape and specification, which cannot meet further requirements. Therefore, it is necessary to stack piezoelectric ceramics to form different sizes and heights, so as to achieve different displacements
