Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, this utility model is further explained explanation.
A kind of high-precision quartz flexure accelerometers, as it is shown in figure 1, include gauge outfit 1 and servo circuit 2, gauge outfit 1 and servo
Circuit 2 forms electrical connection by wire welding, is then glued together formation complete machine with by servo circuit 2 shell and gauge outfit 1；
Described gauge outfit is made up of shell 101, shading ring 102 and watch core 103 3 part, and shading ring 102 sticks with glue and is connected on table
Core 103, then be fixed in shell 101 with glue, as shown in Figure 2；
Described watch core 103 is by upper yoke 310, lower yoke 305, magnet steel 304, pole piece 306, compensation ring 302, quartz pendulous reed
308, coil 307, binding post 301, ceramics pole 303 and bellyband 309 form, and quartz pendulous reed 308 and coil 307 stick with glue and be connected on one
Rise and constitute pendulum assembly；By lower yoke 305, magnet steel 304, pole piece 306, compensate ring 302, ceramics pole 303, binding post 301 glue
The lower torquer of the composition that is connected together；Upper yoke 310, magnet steel 304, pole piece 306, compensation ring 302 are glued together in composition
Torquer；Being placed on by pendulum assembly in the middle of upper and lower torquer, upper and lower torquer is glued together composition watch core by bellyband 309
103, as shown in Figure 3；

Degree.
Operation principle of the present utility model is as follows: this utility model uses capacitance type sensor, presses on quartz pendulous reed 308
Certain requirement is deposited with upper gold film, and this gold film forms two capacitor plates of sensor.Quartz pendulous reed 308 be bonded in above it
Two coils 307 constitute quality testing block, and the mid portion of its coil 307 and quartz pendulous reed 308 constitutes pendulum mass, through two
Individual flexible balance arm 4, makes pendulum mass become a detection quality with preferable single free elastic restraint, straight for sensitive carrier
Linear accelerometer vector.The closed magnet circuit that magnet steel 304, pole piece 306 and upper and lower torquer are formed, they and detection quality
On two coils 307 form the permanent magnet moment-meter of symmetrical operation.The capacitor plate of quartz pendulous reed 308 and the section shape of torquer
Become differential capacitance sensor.When having acceleration or tilting action in time detecting quality, pendulum mass deviates balance position because of inertia two
Putting, capacitance detector differentially detects the displacement of pendulum mass, and exports the signal of telecommunication being directly proportional to this displacement, through servo
Circuit 2 processing and amplifying, to torquer coil with electric current, the motion in magnetic field of this hot-wire coil produces an equilibrant, with
Balanced action, in the inertia force of pendulum mass, makes pendulum mass be in new equilbrium position.The size of current that torquer coil passes through is i.e.
Represent the size at input acceleration or inclination angle, and sense of current i.e. reflects the direction at input acceleration meter or inclination angle.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improve and
Retouching also should be regarded as protection domain of the present utility model.
