Abstract
The invention relates to a protection device for the vibration test of a primary mirror. The protection device comprises a bottom plate, a side plate and an upper cover plate, wherein the side plate is arranged at the periphery of the bottom plate, the upper cover plate is arranged at the upper end of the side plate, a primary mirror cavity is formed by the enclosing the bottom plate, the side plate and the upper cover plate, even number of side plate windows are arranged on the side plate, and side plate protecting gaskets and side plate organic glass are arranged in the side plate windows at intervals in sequence; even number of cover plate windows are arranged on the upper cover plate, upper cover plate protecting gaskets and upper cover plate organic glass are arranged in the cover plate windows at intervals in sequence; a plurality of bottom plate windows are arranged on the bottom plate uniformly, and bottom plate protecting gaskets are arranged in the bottom plate window. According to the protection device for the vibration test of the primary mirror, the technical problem that the primary mirror is easy to collide in the vibration test of the primary mirror is solved, frame type structures are adopted by the plate and the upper cover plate, and the middle of the protection device adopts organic glass materials, so that the weight is lightened, and the primary mirror can be observed at any time.
Description
Technical field
The present invention relates to a kind of primary mirror vibration test protective device.
Background technology
Vibration test is the dynamic environmental test that carries out the camera space optical axis direction.In vibration test, can not observe the situation of primary mirror, also cause the distortion that bumps of primary mirror easily.
Summary of the invention
In order to solve the technical matters that causes the primary mirror collision in the existing primary mirror vibration test easily, the present invention relates to a kind of primary mirror vibration test protective device.
Technical solution of the present invention:
A kind of primary mirror vibration test protective device, its special character is: comprise base plate, side plate and upper cover plate, said side plate is arranged on the periphery of base plate, and said upper cover plate is arranged on the upper end of side plate, and said base plate, side plate and upper cover plate surround the primary mirror chamber,
Have even number side plate window on the said side plate, be arranged at intervals with side plate protective lining and side plate organic glass in the side plate window successively;
Have the even number plate window on the said upper cover plate, be arranged at intervals with upper cover plate protective lining and upper cover plate organic glass in the plate window successively;
Evenly have a plurality of base plate windows on the said base plate, be provided with the base plate protection liner in the said base plate window.
Above-mentioned upper cover plate organic glass is provided with the upper cover plate wire hole, and said side plate organic glass is provided with the side plate wire hole.
Be evenly distributed in a plurality of lifting screws on the above-mentioned upper cover plate.
The advantage that the present invention had:
1, the present invention adopts tower structure at side plate and upper cover plate, and the middle pmma material that adopts had both alleviated weight, can observe the primary mirror situation at any time again.
2, the present invention prevents that at base plate, side plate and upper cover plate position protective lining primary mirror and other parts bump in the vibration processes.
3, the present invention is provided with wire hole and both can the vibration test control line be drawn protective device internal gas generation resonance in the time of can avoiding vibration test again in the middle of upper cover plate organic glass and side plate organic glass.
