Abstract
Disclosed in the utility model is an integrated oscillator rack comprising a piezoelectric ceramic unit, rack body and a metal substrate. The rack body and the metal substrate are made of the same kind of metal material by an integrated way; and the piezoelectric ceramic unit is arranged at the metal substrate. According to the integrated oscillator rack, consumption of the electromechanical conversion energy by the plane sliding and clamping stress can be eliminated in terms of structure; the influence on the integrated oscillator rack by the temperature changing is small; and thus the electromechanical conversion efficiency is ensured.
Description
Technical field
The utility model belongs to earthquake physical prospecting field, relates to the data-collection part of a kind of earthquake physical prospecting sensor, relates in particular to a kind of integral type oscillator frame.
Background technology
The data-collection part of sensor for earthquake physical prospecting, data-collection part is the core technology of piezoelectric sensor, its quality will have influence on sensitivity, the signal to noise ratio (S/N ratio) of sensor, the important parameters such as mechanical-electric coupling efficiency, and ensure that the piezoelectric ceramics substrate of oscillator frame and the connected mode of oscillator frame are very key links.
At present, the normal piezoelectric ceramics substrate adopting and the connected mode of oscillator frame are mainly split type, piezoelectric ceramics substrate and oscillator frame are to process respectively, then by mechanical connection manner, how both are integrated, what the bended piezoelectric acceleration sensor of Chinese patent ZL.200820030163.4 adopted is exactly piezoelectric ceramics substrate and oscillator frame split-type structural, this structure cannot be eliminated and connect the fastening planar slide bringing and nip stress structure, and slip and nip stress will make the electromechanical conversion efficiency of sensor reduce, degree of stability is easily influenced.
Utility model content
The utility model provides the integral type oscillator frame that a kind of electromechanical conversion efficiency is high.
Technical solution of the present utility model is:
Integral type oscillator frame, comprises piezoelectric ceramics, and its special character is:
Described integral type oscillator frame also comprises that described piezoelectric ceramics is arranged on metal substrate by the integrated support body of metal material of the same race and metal substrate.
Above-mentioned metal substrate comprises upper surface and lower surface, and described piezoelectric ceramics sticks on upper surface and the lower surface of metal substrate.
Above-mentioned metal material is beryllium-bronze or stainless steel.
Above-mentioned metal material is high-elastic alloy.
On above-mentioned metal substrate and piezoelectric ceramics, be equipped with center pit, the center pit on metal substrate is concentric with the center pit on piezoelectric ceramics.
Above-mentioned metal substrate be shaped as circle, ellipse or rectangle.
The utility model has the advantages that:
1, electromechanical conversion efficiency is high: because planar slide and nip stress all can make machine-electric switching energy loss, and metal substrate of the present utility model and support body are integrated with metal material of the same race, so the utility model has been eliminated this consumption of two factors to machine-electric switching energy from structure, thereby has ensured electromechanical conversion efficiency.
2, temperature stability is good: because metal substrate of the present utility model and support body are integrated with metal material of the same race, coefficient of thermal expansion and contraction is identical, temperature variation is little on impact of the present utility model, thereby monolithic construction of the present utility model is better than split-type structural.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation that the utility model is provided with center pit.
Reference numeral:
1-support body; 2-piezoelectric ceramics; 3-metal substrate; 4-center pit.
Embodiment
The utility model provides a kind of integral type oscillator frame, as shown in Figure 1, comprise piezoelectric ceramics 2, integral type oscillator frame also comprises by the integrated support body 1 of metal material of the same race and metal substrate 3, metal material can be high-elastic alloy, specifically can adopt beryllium-bronze and stainless steel etc., and beryllium-bronze effect is best; Piezoelectric ceramics is arranged on metal substrate.
Metal substrate comprises upper surface and lower surface, and described piezoelectric ceramics sticks on upper surface and the lower surface of metal substrate.
As shown in Figure 2, in order to make range of application of the present utility model wider, be equipped with center pit 4 on metal substrate and piezoelectric ceramics, the center pit on metal substrate is concentric with the center pit on piezoelectric ceramics, so that assembling.
The shape of metal substrate can be circle, ellipse or rectangle, circular.
Manufacturing process of the present utility model is: first support body and metal substrate time processing are formed, on this support body, there is metal substrate part, and then piezoelectric ceramics is pasted on metal substrate, in this structure, being connected of metal substrate and oscillator frame support body will do not there is not, just do not produce planar slide and nip stress, thereby its electromechanical conversion efficiency is guaranteed yet.
