Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The present invention provides a kind of technical solution referring to FIG. 1-2: a kind of reflecting mirror of drum structure, including reflector body
1, reinforcing rib 2, thin boss 3, fixed mounting hole 4, support column 5 and mounting seat 6, reflector body 1 is parallel with mounting seat 6 to be set
It sets, and reflector body 1 is vertical with support column 5 with mounting seat 6, reflector body 1, support column 5 and mounting seat 6 are in drum knot
Structure, and reflector body 1, support column 5 and mounting seat 6 are integrally machined, three of the back side setting of reflector body 1 but unlimited
In three reinforcing ribs 2, guarantee that reflecting mirror is light-weighted simultaneously, for reinforcing mirror structure rigidity, intensity and optical surface type
Precision, improves the eigenfrequency of reflecting mirror, while reducing dosage, save the cost, center line and the reflector body 1 of support column 5
Reflecting surface is vertical, and the center line of support column 5 passes through the central point of mounting seat 6, and support column 5 is vertical with peace pedestal 6, mounting seat
6 be the understructure of light-weighted three or more a rotational symmetry distribution supporting leg, is guaranteeing the rigidity of structure and intensity
In the case where, lightweight is further realized, support column 5 and 6 joint of mounting seat open up a lightening hole, and lightening hole is circle
Lightening hole, but it is not limited to circle, the support in mounting seat 6 has fixed mounting hole 4, and the center of all fixed mounting holes 4 is arrived
5 center of support column is equidistant, and one thin boss 3 is machined on the supporting leg of mounting seat 6, thin boss 3 is circular ring shape, thin
The internal diameter of boss 3 is identical as fixed mounting hole 4, further decreases the influence of mount stress；Drum knot described in present example
Structure reflecting mirror, the relative position of assembly the design phase by mounting seat 6, fixed mounting hole 4, fixed mounting hole 4 it is thin
Realize that the relative accuracy of assembly realized by requirement on machining accuracy in the position of boss 3；
Installation is simple, during practical set, since reflector body 1, support column 5 and mounting seat 6 are same material one
Body processing, therefore the installation steps of drum structure reflecting mirror and external system are simple, are easy adjustment, and no longer need the one of optical axis
The debugging calibration of cause property；
Mount stress influence it is small, due to the decoupling function of reflecting mirror drum structure, in installation process due to flatness error,
The stress that screw locking generates will not be directly transferred on mirror surface；
The stress generated in installation process will not be directly transferred on mirror surface, and attenuation ratio is up to 100 times, to protect
Surface precision is demonstrate,proved；
Thermal adaptability is good, due to reflector body 1, support column 5 and mounting seat 6, is integrally machined for same material, because
This, when environmental change, reflector body 1 is not present to be generated mirror surface and becomes because of mismatching with the thermal expansion coefficient of other materials
Shape is suitble to space application；
Lightweight, for comparison is with the fused quartz reflecting mirror of size, drum structure reflecting mirror is in identical surface precision item
Under part, thickness can be very thin, therefore has smaller rotary inertia and higher resonance frequency, is suitable for weight, impact
The demanding situations of adaptability such as vibration；
Loss of weight compares table, and silicon carbide mirror is up to 2.7 times with respect to fused quartz reflecting mirror loss of weight.
Have a wide range of application, drum structure reflecting mirror and external system are connected and fixed using screw, therefore are avoided traditional
Adhesive means the problems such as there are deflation rates, glue aging in space environment；
The course of work is stablized, and reflector body 1 will not generate mirror surface loosening in rotary course, move the stress of generation by
In the decoupling function of drum structure, it will not be directly transferred on mirror surface, influence image quality；
It is easy to disassemble, it is that drum structure reflecting mirror demounting procedure is simple, tears open with the maximum difference of traditional gluing reflecting mirror
The influence unloaded to reflecting mirror and external system is small, reusable.
