Description
Technical field
The present invention relates to a kind of precision machinery devices, and in particular to a kind of telescope primary mirror mandrel machine based on static pressure principle
Structure and correction oil injection method, the demand suitable for telescope primary mirror and the radial supporting mechanism axially decoupled.
Background technique
The primary mirror of telescope is the maximum optical element of telescopic system, and the support effect of primary mirror is to telescope at image quality
Amount has a great impact.And the support of primary mirror is generally made of axial support and radial (or lateral) support, good support system
It is required that axially and radially support it is full decoupled, it is non-interference.Mandrel mechanism is a kind of common primary mirror radial supporting mechanism, often
The mandrel mechanism seen is made of mandrel outer ring, mandrel inner ring and mandrel pillar etc..There are mainly two types of mandrel mechanisms: a kind of inner ring and
Outer ring uses hard contact, and outer ring shape is typically designed as drum type at this time, is line contact between outer ring and primary mirror mesoporous；It is another
It is contacted between outer ring and primary mirror mesoporous using cylinder, is bonded together using structure glue, and inner ring and outer ring uses flexible sheet
Connection, flexible sheet axial rigidity is small and radial rigidity is big.But both modes cannot all accomplish and axial support is full decoupled,
There are frictional force between the drum type outer ring and primary mirror mesoporous of first way；The flexible sheet rigidity that the second way uses is not
It is infinitely small.Therefore need to design the full decoupled radial support of a kind of and axial support.
Summary of the invention
The present invention mentions to solve the problems, such as that it is full decoupled with axial support that existing telescope primary mirror mandrel can not be accomplished
For a kind of telescope primary mirror mandrel mechanism and correction oil injection method based on static pressure principle.

The correction oil injection method of telescope primary mirror mandrel mechanism based on static pressure principle, this method are realized by following steps:
Mandrel mechanism is horizontally arranged first, interior hexagonal plunger is laid down, then passes through the oiling input on mandrel outer ring
Mouth oiling, hydraulic oil are flowed up by oiling input port, are finally flowed out from oiling delivery outlet；
After filling, oiling delivery outlet is sealed using hexagonal plunger, then mandrel mechanism rotation 180 degree is inputted oiling
Mouth is placed upward, after standing a period of time, is sealed oiling input port with interior hexagonal plunger, and oiling is completed.
Beneficial effects of the present invention: the present invention is using the closed oil pocket of static pressure principle design as the radial direction branch of primary mirror
Support can accomplish that radial rigidity is infinitely great and axial rigidity is infinitely small, meet radial support and axially support full decoupled need
It asks.Can guaranteeing primary mirror, axially support and mandrel mechanism can be full decoupled under two states, and non-interference, primary mirror is protected always

Specific embodiment
Specific embodiment one illustrates present embodiment in conjunction with Fig. 1 to Fig. 4, the telescope primary mirror core based on static pressure principle
Platen 2 in axis mechanism, including mandrel briquetting 1, upper film, upper film external pressure plate 4, mandrel outer ring 5, interior hexagonal plunger 6, in mandrel
Circle 9, lower film external pressure plate 10, rolling film 11, platen 12 and mandrel column 13 in lower film.Mandrel component is mainly by mandrel
Circle 9, mandrel outer ring 5 and mandrel column 13 form.Wherein mandrel outer ring 5 and the contact of 1 mesoporous of primary mirror, pass through gluing between the two
Knot is together.Mandrel column 13 is mounted in mirror cell 14 by screw, and mandrel inner ring 9 is then fixed on mandrel by mandrel briquetting 1
On column 13.Mandrel inner ring 9 and mandrel outer ring 5 are then linked together by upper and lower two panels rolling film 11, and rolling film 11 is logical
Cross that platen 2 in film, upper film external pressure plate 4, platen 12 and lower film external pressure plate 10 are separately fixed at outside mandrel in lower film
On circle 5 and mandrel inner ring 9.Mandrel inner ring 9, mandrel outer ring 5 and rolling film 11 constitute a closed chamber 3 together, in closed chamber 3
It is filled with low temperature hydraulic oil, hydraulic oil is to pass through interior hexagon prism after filling by two pouring orifices injection on mandrel outer ring 5
6 sealing of plug.
In present embodiment, when primary mirror direction is vertical, since the closed chamber that mandrel mechanism of the invention uses is full of liquid
Pressure oil, and liquid does not have a shear stiffness, and the shear stiffness of rolling film also very little, therefore the weight of primary mirror is completely by axially propping up
Support burden.When primary mirror is directed toward it is horizontal when, the gravity of primary mirror can cause the stereomutation of closed chamber, and liquid is incompressible, i.e., this
When mandrel mechanism oil pocket rigidity it is infinitely great, therefore primary mirror weight is undertaken by mandrel mechanism completely.
Specific embodiment two illustrates that present embodiment, present embodiment are specific embodiment one in conjunction with Fig. 3 and Fig. 4
The correction oil injection method of the telescope primary mirror mandrel mechanism based on static pressure principle, this method are realized by following procedure:
Mandrel mechanism is horizontally arranged first, interior hexagonal plunger 6 is laid down, then the oiling input by being provided in Fig. 3
Mouth oiling, low temperature hydraulic oil are gradually flowed up by lowest part, are finally flowed out from oiling delivery outlet.After filling, first will
The 6 precession mandrel outer ring 5 of hexagonal plunger of oiling delivery outlet, oiling delivery outlet is sealed.
Then mandrel mechanism is rotated and places original oiling input port upward, (generally seven after standing a period of time
It or so), oiling input port is also being sealed with interior hexagonal plunger 6, is completing the oiling of mandrel mechanism.
The temperature range of low temperature hydraulic oil described in present embodiment is between -30 DEG C to -50 DEG C.
Illustrate present embodiment in conjunction with Figure 34, closed oil pocket when giving mandrel mechanism in Fig. 4 as radial support by
Power schematic diagram.From the figure, it can be seen that the weight of primary mirror is undertaken by mandrel mechanism completely when 7 direction level of primary mirror.Assuming that close
Closed chamber 3 is had downwards displacement Z by primary mirror gravity, then the circular arc portion A and B in 3 section of closed chamber, are respectively deformed into elliptic arc
A' and B'.Circular arc A is consistent with the length of elliptic arc A', and circular arc B is consistent with the length of elliptic arc B'.It is constituted due to same material
Geometric figure, circular area is maximum, and the area of circular arc A and B are centainly greater than elliptic arc A' and B'.I.e. closed chamber 3 is being led
Volume can reduce when mirror gravity, and low temperature hydraulic oil is filled in closed chamber 3, and the bulk modulus of liquid is very big, the body of liquid
Product is almost incompressible, the volume compression very little that closed chamber 3 generates, and the gravity direction displacement Z of primary mirror 7 is with regard to very little, therefore core
The radial support rigidity of axis mechanism is very big, and primary mirror weight is supported by mandrel mechanism completely.And liquid internal tangential friction force is very
Small, 11 shear stiffness of rolling film is also very low, and when primary mirror direction is vertical, primary mirror weight is completely by axially supporting 8.Therefore it uses
The mandrel mechanism can guarantee primary mirror in different pitch attitudes, and radial support and axial support are full decoupled, non-interference.
The mandrel mechanism designed in present embodiment carries out radial support to primary mirror using static pressure principle, it is ensured that radial
Rigidity is big and axial rigidity is almost nil, to guarantee telescope primary mirror difference pitch attitude with axial support decoupling well
Under good support effect.
