Abstract
The utility model is specifically a kind of air floating platform for high-precision glass polishing machine；It is characterized in that：It includes top rotary table, undersetting, intermediate sleeve, central shaft, auxiliary bearing, central shaft is vertical in undersetting centre, intermediate sleeve and top rotary table are sequentially sleeved on central shaft, and auxiliary bearing is provided between top rotary table and central shaft and between intermediate sleeve and central shaft；It is hollow and provided with air delivering pipeline that the bottom surface or side of the intermediate sleeve, which are provided with inside transfer port, central shaft, and the transfer port connection of described air delivering pipeline one end and intermediate sleeve, the other end is connected with compressed gas source.The utility model between top rotary table, undersetting by being provided with the intermediate sleeve of transfer port, compressed air is inputted into the transfer port of intermediate sleeve, so that being filled with compressed air between top rotary table and undersetting, after enough compressed airs are entered between top rotary table and undersetting top rotary table can be made to float from undersetting top surface, now be rotated by top rotary table.
Description
Technical field
The utility model is related to high-precision polissoir field, and specifically a kind of air supporting for being used for high-precision glass polishing machine is put down
Platform.
Background technology
Glass polishing machine have machining accuracy it is high, it is high in machining efficiency the characteristics of, it is used for the high-precision surface of heavy-calibre element
Make, such as the processing of macrotype optical mirror piece.However, many rollings by bearing between rotating disk and bearing of traditional glass polishing machine
Rub to realize rotation each other；And rolling friction be present, thus existing glass polishing machine machining accuracy without
Method is improved.
The content of the invention
The purpose of this utility model is there is provided one kind to be used to that glass polishing machine machining accuracy can be improved, utilizes air supporting principle
Realize the air floating platform mutually rotated.
In order to achieve the above object, the utility model is realized in：
A kind of to be used for the air floating platform of high-precision glass polishing machine, it includes top rotary table, undersetting, intermediate sleeve, central shaft, auxiliary
Bearing, central shaft is sequentially sleeved on central shaft in undersetting centre, intermediate sleeve and top rotary table vertically, top rotary table and central shaft
Between and intermediate sleeve and central shaft between be provided with auxiliary bearing；The bottom surface or side of the intermediate sleeve are provided with transfer port,
It is hollow inside central shaft and provided with air delivering pipeline, the transfer port connection of described air delivering pipeline one end and intermediate sleeve, the other end
It is connected with compressed gas source；Wherein, top rotary table and undersetting are granite materials.
Described is used for the air floating platform of high-precision glass polishing machine, and the transfer port has multiple, is uniformly arranged in annular
On the side wall of intermediate sleeve.
The utility model uses above-mentioned design, its centre by being provided with transfer port between top rotary table, undersetting
Set, by inputting compressed air in the transfer port to intermediate sleeve so that be filled with compressed air between top rotary table and undersetting, and by
In top rotary table, undersetting be granite material, therefore when enough compressed airs are entered between top rotary table and undersetting
After top rotary table can be made to float from undersetting top surface, now rotated by top rotary table.
Brief description of the drawings
Fig. 1 is the top view of this air floating platform.
Fig. 2 be in Fig. 1 A-A to sectional view.
Embodiment
The utility model is further illustrated below by way of specific embodiment.
As shown in Figure 1 and Figure 2, it is a kind of to be used for the air floating platform of high-precision glass polishing machine, it include top rotary table 5, undersetting 1, in
Between set 2, central shaft 3, auxiliary bearing 3, central shaft 3 is sequentially sleeved in the centre of undersetting 1, intermediate sleeve 2 and top rotary table 5 vertically
On central shaft 3, auxiliary bearing is provided between top rotary table 5 and central shaft 3 and between intermediate sleeve 2 and central shaft 3；In described
Between set 2 bottom surface or to be provided with inside transfer port, central shaft 3 be hollow and provided with air delivering pipeline for side, the air delivering pipeline one
End is connected with the transfer port of intermediate sleeve 2, and the other end is connected with compressed gas source；Wherein, top rotary table 5 and undersetting 1 are granite
Material.
Described is used for the air floating platform of high-precision glass polishing machine, and the transfer port has multiple, is uniformly arranged in annular
On the side wall of intermediate sleeve 2.
The utility model uses above-mentioned design, and it between top rotary table 5, undersetting 1 by being provided with transfer port
Between cover 2, by inputting compressed air in the transfer port to intermediate sleeve 2 so that compression is filled between top rotary table 5 and undersetting 1 empty
Gas, and because top rotary table 5, undersetting 1 are granite materials, thus when enough compressed airs enter top rotary table 5 with
After between undersetting 1 top rotary table 5 can float from the top surface of undersetting 1, now rotated by top rotary table 5.And pass through this
Rotating manner is planted, the advantage is that, during rotation, be not in contact between top rotary table 5 and undersetting 1, the bearing for rotation is also held
By top rotary table 5 or the gravity of undersetting 1, and then the abrasion of bearing is reduced, improve the precision of processing operation.
Claims (2)
