Description
Technical field
The present invention relates to a kind of high temperature turntable mechanisms carrying out non-spherical reflector processing by the way of centrifuging founding.Belong to
In the protection field of optical manufacturing mechanical device.
Background technology
Using this mode of centrifugation founding aspherics glass reflector, main process principle is：When to melt
When glass is rotated, a paraboloid, the paraboloid formed in this way can be formed in the glass melt surface of rotation
Surface smoothness is very high, can be used for making optical mirror substrate.The mirror substrate made in this way, using table
Mirror polish, plated film are processed into optical mirror.Non-spherical reflector is processed by the way of this centrifugation founding
Major advantage is, is convenient for the processing and forming of large caliber reflecting mirror, due to having centrifuged the surface face type formed during founding
Through to be aspherical, therefore save the time of a large amount of follow-up grinding and polishing.
During carrying out non-spherical reflector centrifugation founding, turntable needs continuous running that glass can be made to be in molten
Melt the high temperature under state, is carried on turntable and carry out the mold that optical glass centrifuges founding, turntable driven mold common rotation, when
Melt-glass cools down after forming the face type gone for, is cooled down, final to obtain non-spherical reflector substrate.
The processing of non-spherical reflector substrate is carried out in this way, and for turntable, there are two important requirements：
One, to the processing temperature of glass material usually all in 600-1500 DEG C of high temperature range, processing temperature depends on will be into
The optical glass material of row processing, therefore turntable will can guarantee stable operation at high temperature.
Two, it wants that insulation processing can be carried out between high temperature turntable and main power shaft.Since the temperature of active vertical shaft cannot
It is excessively high, the excessively high rotation precision that will influence turntable.Therefore it while ensureing that in-furnace temperature is stablized, reduces from turntable to active force
The heat transference efficiency of axis, and can effectively be radiated, protection main shaft temperature is unlikely to excessively high.
Therefore, the turntable that can be operated in 700-1200 DEG C of high temperatures is produced, and is carried out in turntable and main power shaft
It is the key component of this kind of processing method using heat-shield mechanism when connection, between connecting portion and turntable.Aluminium oxide ceramics have compared with
Good conductibility, mechanical strength and heat-resisting quantity.And zirconia ceramics has high tenacity, high-flexural strength and high-wearing feature, it is excellent
The advantages that different heat-proof quality, coefficient of thermal expansion is close to steel.According to the different performance of both ceramics, applied in high temperature
The different location of turntable.In the present invention, aluminium oxide ceramics and zirconia ceramics material have largely been used with ensure turntable and
The high-temperature stability and heat-proof quality of heat-shield mechanism, and the shape of heat-shield mechanism cooling fin is designed, ensure running
Good heat-insulated and heat dissipation performance in journey.The position for being thermally shielded heat preservation is being needed to use high density aluminosilicate fiberboard simultaneously,
Because its thermal and insulating performance is good while having lower density, the dead weight of turntable is reduced.
Invention content
The present invention is to centrifuge the high temperature turntable mechanism used needed for founding making for aspherics glass reflector
Structure design.Major function is used in heating furnace, for being rotated to the glass material under high temperature fused state, is utilized
The centrifugal force that rotation generates forms the high precision turntable of aspherical face type.
It is following two the invention aims to solve the problems, such as：
1, turntable can stable operation under 600-1500 DEG C of the condition of high temperature.
2, it needs to be thermally shielded between high temperature turntable and steel flanges disk for main power shaft connection and radiating treatment, protect
Card works long hours under state, is attached and drives the line shaft temperature that turntable is rotated certain with steel flanges disk
In range, it is unlikely to influence the rotation precision of turntable.
In order to solve the above technical problems, technical solution of the present invention is：
A kind of aspherics glass reflector centrifugation founding high temperature turntable mechanism, overall structure is as shown in Figure 1, Fig. 2 is height
The vertical view of warm turntable mechanism.In the present invention, aluminium oxide ceramics and zirconia ceramics material have largely been used to ensure to turn
The high-temperature stability and heat-proof quality of platform and heat-shield mechanism, and the shape of heat-shield mechanism cooling fin is optimized, ensure
Good heat-insulated and heat dissipation performance in the process of running.The position for being thermally shielded heat preservation is being needed to use alumina silicate fibre simultaneously
Plate reduces the dead weight of turntable because its thermal and insulating performance is good while having lower density.
In Fig. 1, turntable upper surface uses alumina ceramic plate 1, because aluminium oxide ceramics has very high high temperature resistance,
Also there is good thermal conductivity simultaneously, be easy to be transmitted to the heat in stove by way of heat transfer in mold on it.
Aluminosilicate fiberboard 2 is used at the middle part of turntable in Fig. 1, plays the role of heat preservation to in-furnace temperature.Simultaneously also to having in Fig. 1
The cast iron plate 3 of flanged joint plays the role of temperature protection.In alumina ceramic plate 1, alumina-silicate ceramic fibre plate 2 and there is method
It is connected with nut using 8 hexagon socket head cap screw of zirconia ceramics between the cast iron plate 3 of orchid connection, since the bolt is from turntable upper surface
High-temperature region cross the low-temperature space of lower surface, and zirconia ceramics material coefficient of thermal expansion is small, while thermal conductivity coefficient is low has
Heat-insulated effect.Steel flanges disk 7 is used between the line shaft of driving turntable rotation be attached in Fig. 1.With flange
Between the cast iron plate 3 and steel flanges disk 7 of connection, it is overlapped using zirconia ceramics piece 5 and stainless steel fin 6 to be formed
Heat-insulated, cooling mechanism, and be attached using bolt 4.During use, steel flanges disk 7 is carried out with line shaft in Fig. 1
Connection drives turntable to be rotated by dynamic vertical shaft.
It needs to be thermally shielded and cooling mechanism such as Fig. 3 between high temperature turntable and the steel flanges disk connected for main power shaft
