Description

A kind of pluggable piezoelectric polarization device high temperature test fixture
Technical field
The invention belongs to piezoceramic material technical field of performance test, it is related to a kind of pluggable piezoelectric polarization device high Warm test fixture.
Background technology
Piezoceramic material is a kind of functional material that can be converted mechanical energy and electric energy, extensive based on this characteristic The high-technology fields such as mobile communication, satellite broadcasting, electronic equipment, instrument and meter and Aero-Space are applied to, referred to as can not The modernization critical material and element for lacking.With developing rapidly for science and technology, the use scope of piezoelectric ceramic piece becomes more Plus extensively, based on this, develop more high-curie temperature, larger piezoelectric stress constant, the novel piezo-electric ceramic of friendship high mechanical properties Material turns into the task of top priority.The new piezoelectric element polarization process of research is essential.But based on experiment the need for, often The material and shape and thickness of individual test specimen all need to carry out different shapings, cause that test specimen reaches test request after then polarizing. But the test fixture structure of traditional polarization device is excessively unreasonable, operation inconvenience is particularly not easy to repetition plug and uses, It is difficult to clamp for the piezoelectric ceramic piece of different-thickness, therefore same test fixture can not realize the piezoelectric ceramic piece of different-thickness Polarization.
The content of the invention
A kind of shortcoming it is an object of the invention to overcome above-mentioned prior art, there is provided pluggable piezoelectric polarization device High temperature test fixture, the fixture can realize the polarization of the piezoelectric ceramic piece of different-thickness.
To reach above-mentioned purpose, pluggable piezoelectric polarization device high temperature test fixture of the present invention includes piezoelectricity pole Fixture and electrode plate are put in makeup, and piezoelectric polarization device fixture includes collets, lower end plug, first baffle, second baffle, the One electrode, second electrode, the first spring and second spring;
Lower end plug is fixed on the lower end of collets, and first baffle and second baffle are both secured to the upper end of collets, and The positive pole and negative pole of lower end plug are connected with first baffle and second baffle, and first electrode and second electrode are located at first baffle Between second baffle, be connected by the first spring between first electrode and first baffle, second electrode and second baffle it Between be connected by second spring, and first electrode, just to second electrode, electrode plate is provided with what is be engaged with lower end plug Jack, electrode plate is connected with external polarizer apparatus.
Also include clamp, clamping collets by clamp is inserted into jack lower end plug.
The depth of jack is 5-8mm.
First electrode and second electrode are circular configuration or rectangular configuration.
The surface of clamp is coated with insulating barrier.
First baffle, second baffle, first electrode, second electrode, the first spring and second spring are by conductive material It is prepared from.
The invention has the advantages that:
Pluggable piezoelectric polarization device high temperature test fixture of the present invention in concrete operations, by piezoelectric ceramic piece Be held between first electrode and second electrode, realize the clamping of piezoelectric ceramic piece, at the same first electrode by the first spring with First baffle is connected, and second electrode is connected by second spring with second baffle, so that first electrode and second electrode The piezoelectric ceramic piece of different-thickness and different size shape can be clamped, lower end plug is then inserted in inserting for electrode plate again Kong Zhong, then electrode plate is connected with external polarizer apparatus, you can realize different-thickness, different size, different shape piezoelectricity The polarization of potsherd, simple structure is easy to operate, can adapt to the piezoelectric ceramic piece of different-thickness.Lower electrode plate is set Multiple jacks, can once polarize multiple piezoelectric ceramic pieces, solve the problems, such as that polarization volume is low, while the difference that can polarize simultaneously Thickness, piezoelectric ceramic piece of different shapes, beneficial to contrast test is done under same polarization condition, save test period, and it is right to increase Than the reliability tested, the unnecessary waste of electric energy and heat energy is reduced.
Further, clamp collets by clamp lower end plug is inserted into jack, the surface of clamp is coated with insulation Layer, so as to effectively reduce the potential safety hazard that user's misoperation is caused.
