Catoptron is the critical component of reflective optical system, and catoptron support technology is one of most critical technology in the application of large caliber reflecting mirror engineering.Large caliber reflecting mirror is generally operational in the state of facing upward or vertical state, all comparative maturities of the supporting way under this two states; And working in while having a down dip state, it is complicated many that supporting construction is wanted compared with first two state, can not use large caliber reflecting mirror at the state of facing upward or the vertical supporting way of state.
Summary of the invention
According to above-mentioned requirements, the design provides a kind of back side gummed lever weighting support scheme, to meet the support requirement of catoptron at the state of having a down dip.
For achieving the above object, the design realizes by following technological means:
A kind of large caliber reflecting mirror state supporting construction that has a down dip, it is characterized in that: comprise lever construction and web member, the lever of described lever construction is hinged through the hinge to fulcrum, described lever one end connects weight, one end and web member are connected through the hinge, and described web member is fixed on mirror mirror back at tie point by the mode of glue bond.
Preferably, described a kind of large caliber reflecting mirror state supporting construction that has a down dip, is characterized in that: the multiple that the quantity of described tie point is three.
Preferably, described a kind of large caliber reflecting mirror state supporting construction that has a down dip, is characterized in that: the diameter of described catoptron is 1.5mm.
Preferably, described a kind of large caliber reflecting mirror state supporting construction that has a down dip, is characterized in that: the quantity of described tie point is 18.
Preferably, described a kind of large caliber reflecting mirror state supporting construction that has a down dip, it is characterized in that: described tie point is positioned on two different circumference of diameter taking the catoptron center of circle as the center of circle, and 12 in described tie point are distributed on big circumference, and all the other 6 are distributed on small circumference.
Preferably, described a kind of large caliber reflecting mirror state supporting construction that has a down dip, is characterized in that: the position that is positioned at a tie point on small circumference forms isosceles triangle with the position that is positioned at two tie points on big circumference.
Preferably, described a kind of large caliber reflecting mirror state supporting construction that has a down dip, is characterized in that: described tie point be shaped as circle.
Preferably, described a kind of large caliber reflecting mirror state supporting construction that has a down dip, is characterized in that: the diameter of described circle is 50mm.
The invention has the beneficial effects as follows: this back side gummed lever weighting support scheme, in ensureing catoptron support accuracy, stressed, reliable operation, the version that can carry out by changing the position of weight on lever adjustment (adjusting) lever are light and handy.Be applicable to high-precision optical supported design, be widely used in bigbore mirror support system.
Brief description of the drawings
Fig. 1 is the design's structural representation, and Fig. 2 is mirror back surface tie point position view.
The implication of drawing reference numeral is as follows: 1 tie point, 2 web members, 3 hinges, 4 fulcrums, 5 weights, 6 levers, 7 minute surfaces, 8 isosceles triangles.
Embodiment
Below in conjunction with Figure of description, design is further described.
As shown in Figure 1, 2, a kind of large caliber reflecting mirror state supporting construction that has a down dip, it is characterized in that: comprise lever construction and web member 2, the lever 6 of described lever construction is connected in fulcrum by hinge 4, described lever 6 one end connect weight 5, one end is connected by hinge 3 with web member 2, and described web member 2 is fixed on mirror mirror 7 backs at tie point 1 by the mode of glue bond.
This kind of design proposal, stressed, reliable operation, the version that can carry out by changing the position of weight on lever adjustment (adjusting) lever are light and handy.Tie point and minute surface gummed is connected, simple in structure, and unique what should be noted that is exactly the problem of bond area.On the one hand, the cohesive strength of glue is limited, and bond area is larger, and the reliability of mechanism is just better; On the other hand, two aspects of bonding, due to expanded by heating coefficient difference, cause temperature distortion size also different, and bond area is fewer, and the possibility of coming unstuck is just less.
Preferably, described a kind of large caliber reflecting mirror state supporting construction that has a down dip, is characterized in that: the multiple that the quantity of described tie point 1 is three.
Reduce as much as possible the area of gummed, increase the quantity supporting and meet bonding strength.
