Description
Technical field
The utility model relates to gyroscope technology field, particularly relates to a kind of rate gyroscope vibration-proof structure.
Background technology
Rate gyroscope is a kind of precision instrument for measuring object angular velocity, but the working environment principal feature due to rate gyroscope is strong vibration, High Rotation Speed, therefore rate gyroscope is very easily affected by vibration, the performance index such as its zero-bit is worth partially can change under vibration, thus affect the measuring accuracy of rate gyroscope, and then the serviceability of rate gyroscope is caused to meet the demands.
The Sensitive Apparatus of rate gyroscope is mainly arranged in the inner housing that profile is rectangular parallelepiped by the vibration damping mode of current rate gyroscope, but but there is rate gyroscope zero-bit under High Rotation Speed environment and be partially worth the problem that drift occurs, its reason rate gyroscope is three direction (x in the course of the work, y, z) all vibration is had, therefore its position all needs to be fixed in three directions, a kind of structure guaranteed rate gyroscope of completely isolated vibration therefore must be designed from vibration effect.
Utility model content
For prior art above shortcomings, the purpose of this utility model is just to provide a kind of rate gyroscope vibration-proof structure, can by isolating technique suffered in the rate gyroscope course of work, thus the impact avoiding rate gyroscope to be vibrated, to improve the measuring accuracy of rate gyroscope.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of rate gyroscope vibration-proof structure, comprise the shell body that top is uncovered, be connected with shell body upper end and the overhead guard that shell body is closed, and the inner housing be installed in shell body, described inner housing is cuboid structure, the inner chamber of described shell body is the rectangular cavities can holding inner housing, it is characterized in that: be arranged with a rubber shock-absorbing cover respectively at the top and bottom of inner housing, described rubber shock-absorbing cover is annular plate structure, its outward flange has the flange be bent to form to rubber shock-absorbing cover side, and the flange of two rubber shock-absorbing covers is arranged in opposite directions, this inner housing and rubber shock-absorbing cover are fitted in shell body by overhead guard, and inner housing and shell body and the position between inner housing and overhead guard are fixed by two rubber shock-absorbing covers.
Further, described rubber shock-absorbing cover is corresponding with inner housing and middle part has the rectangular ring structure of rectangular opening.
Further, the flange of described rubber shock-absorbing cover and the corresponding position, middle part of each side of inner housing have breach, make to have gap between the flange of the middle part of each side of inner housing and rubber shock-absorbing cover.
Further, the surrounding of described overhead guard has downward flange, and this flange combines with the coboundary of shell body.
Compared with prior art, the utility model tool has the following advantages: structure is simple, can effectively at three direction (x, y, z) on, rate gyroscope is fixed, thus the vibration that effective isolation rate gyroscope is subject in the course of the work, avoid the impact that rate gyroscope is vibrated, and then effectively improve the measuring accuracy of rate gyroscope.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment: see Fig. 1 to Fig. 4, a kind of rate gyroscope vibration-proof structure, comprises the uncovered shell body 1 in top, is connected with shell body 1 upper end and the overhead guard 3 closed by shell body 1 and installing and inner housing 2 in shell body 1.Described inner housing 2 is cuboid structure, and the inner chamber of described shell body 1 is the rectangular cavities can holding inner housing 2.Be arranged with a rubber shock-absorbing cover 4 respectively at the top and bottom of inner housing 2, described rubber shock-absorbing cover 4 is annular plate structure, and its outward flange has the flange be bent to form to rubber shock-absorbing cover 4 side, and the flange of two rubber shock-absorbing covers 4 is arranged in opposite directions.This inner housing 2 and rubber shock-absorbing cover 4 are fitted in shell body 1 by overhead guard 3, and inner housing 2 and shell body 1 and the position between inner housing 2 and overhead guard 3 are fixed by two rubber shock-absorbing covers 4.
Described rubber shock-absorbing cover 4 is corresponding with inner housing 2 and middle part has the rectangular ring structure of rectangular opening; Thus can carry out better assembling and improving damping effect.
The flange of described rubber shock-absorbing cover 4 and the corresponding position, middle part of each side of inner housing 2 have breach, make to have gap between the middle part of each side of inner housing 2 and the flange of rubber shock-absorbing cover 4; Thus increase the deformability of rubber shock-absorbing cover 4, to improve damping effect further.
The surrounding of described overhead guard 3 has downward flange, and this flange combines with the coboundary of shell body 1; Assemble convenient, top rubber shock-absorbing cover 4 can be connected in overhead guard 3, and then cover on shell body 1 by overhead guard 3, installation stability is better.
The utility model can effectively at three direction (x, y, z) on rate gyroscope is fixed, thus the effectively vibration that is subject in the course of the work of isolation rate gyroscope, avoid the impact that rate gyroscope is vibrated, and then effectively improve the measuring accuracy of rate gyroscope.
Finally it should be noted that, above embodiment is only in order to illustrate the technical solution of the utility model but not restriction technologies scheme, those of ordinary skill in the art is to be understood that, those are modified to the technical solution of the utility model or equivalent replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of right of the present utility model.
