Description
Technical field:
This patent relates to the plane mirror sensing assembly of space remote sensing and laser communication instrument, specifically refers to by plane
The sensing assembly of the coupling member composition of reflecting mirror, rotating shaft and connection plane mirror and rotating shaft.
Background technology:
Frequently with plane mirror directing mechanism in space remote sensing and laser communication instrument: for remote sensing instrument, point to
Illuminating apparatus structure is in order to expand imaging viewing field；For laser communication, directing mechanism is then used for being scanned following the tracks of to quasi goal, sets up letter
Road.The unstressed support of high accuracy of directing mechanism midplane reflecting mirror is always a technical barrier.Current method for supporting master
Having two kinds, one is respectively to install a rotating shaft in plane mirror two sides, and plane mirror carries out supported on both sides, this way
Making mirror body become a section of gyroaxis, on the one hand the axiality of mirror body both sides rotating shaft is difficult to ensure that, causes axle system to have bigger
Additional erection stress, instrument in orbit time shorten the moving component life-span；On the other hand erection stress will feed back on mirror body,
Affect mirror shape precision, finally affect the image quality of instrument.A kind of employing leads to spindle center mounting means, i.e. at mirror body
Side is provided with a through hole, and concentric shafts runs through mirror body, and arranges contiguous block in concentric shafts center and couple with mirror body, this
Mode can overcome the problem of revolution concentricity, but arranges through hole at mirror body side surface, destroys the integrity of mirror body itself, right
The rigidity of mirror body has certain impact, and through hole is typically all disposed within the axis of symmetry, is supported on the center of mirror body, certainly will be right
Jing Ti center minute surface surface figure accuracy has considerable influence, for the laser beam of energy Gauss distribution, loss core
Surface figure accuracy can cause bigger performance loss.Simultaneously because plane mirror typically uses back to alleviate, barycenter very close to
Minute surface, and in order to keep certain minute surface thickness, logical mandrel axis of rotation can not pass through the mirror body constitution heart, this makes mirror body needs
Carry out counterweight at back to reach static balance, be the most unfavorable for this spaceflight apparatus the most limited to weight and volume
's.
Summary of the invention:
Based on problem present on above-mentioned existing plane mirror structure, this patent proposes what a kind of crankshaft center supported
Draw bail, this structure ensure that the integrity of mirror body, improves the rigidity in mirror body especially centre；Simultaneously by design
The axis of rotation of bent axle is by pointing to mirror assembly barycenter, it is achieved around the static balance of axis of rotation, it is not necessary to increase unnecessary counterweight knot
Structure.By the precision controlling of coupling member, can effectively improve connection stress and the hot adaptability of mirror body, it is achieved high surface figure accuracy
Clamping.
The plane mirror optics of this patent points to assembly and includes: plane mirror, bent axle and plane mirror and song
Coupling member between axle.
Described plane mirror 1 is elliptic plane mirror, and mirror body back arranges and alleviates groove.Plane mirror 1 back is arranged
There is datum level 101, as the benchmark installing connecting column 2；Plane mirror 1 back is provided with four symmetrical blind holes 102,
Size matches with four connecting columns 2, and four blind holes 102 arrange and concentrate on Jing Ti center；
Having storage glue lattice 203 on described connecting column 2 face of cylinder, bonding force during in order to increase splicing ensures that glue-line is thick simultaneously
Degree.The lug 202 of three circumference uniform distributions is had, when connecting column 2 loads plane mirror 1 blind hole 102 as location on connecting column 2
Use.Connecting column top plan 201 is coupled by the first screw 4 with butterfly keyset 3, and top plan 201 planarity requirements is not
More than 0.002mm, top plan 201 has the first screw 204 in order to couple butterfly keyset 3；
On described butterfly keyset 3, plane 301 and bent axle 5 is coupled by the second screw 6, upper plane 301 is provided with
The second screw 302 that bent axle 5 couples, lower plane 304 couples with 4 connecting columns 2, and plane 304 center is arranged in each of the lower
There is the first through hole 303, pass for the first screw 4；
Described bent axle 5 center has mounting plane 502, bent axle 5 back to be provided with the second through hole 503, wears for the second screw 6
Cross, bent axle 5 has two mounting flanges 501, couples with the apparatus for rotating of peripheral hardware.The centre bore axis of mounting flange 501 passes through
The barycenter of whole assembly.
Coat epoxy glue in connecting column 2 face of cylinder storage glue lattice 203, fill in plane mirror 1 back blind hole 102, plug
Enter rear lug 202 to develop with datum level 101, show that connecting column 2 is installed and put in place.After epoxy glue solidifies, by four connecting columns 2
Top plan 201 repair grind coplanar.Then installing butterfly keyset 3 on top plan 201, the first screw 4 leads to through first
Hole 303 is fixed on the first screw 204, completes to couple with plane mirror 1 by butterfly keyset 3 by being spirally connected；Second screw 6
On bent axle 5, the second through hole 503 is fastened on butterfly keyset 3 second screw 302, and bent axle 5 mounting plane 502 turns with butterfly
On fishplate bar 3, plane 301 is fitted, the centre bore axis of crankshaft installed flange 501 barycenter by whole assembly.
The advantage of this patent is:
1. by the central supported of bent axle, avoided the problem opening through hole on mirror body, it is ensured that the integrity of mirror body, carried
The high rigidity in mirror body especially centre, the clamping making mirror body comprise the unified high surface figure accuracy in centre is able to reality
Existing.
2. it is passed to point to mirror assembly barycenter by the axis of rotation of design bent axle, it is achieved quiet around axis of rotation is put down
Weighing apparatus, it is not necessary to increase unnecessary counter weight construction, saved volume and the quality resource of assembly is significant for space product；
