Description
Technical field
The utility model relates to a kind of graphite grazing seat grinding tools.
Background technique
Graphite grazing is using more and more extensive at present.Especially bridging type divides valve graphite-seal ring, is widely used in aviation, boat
In the military projects such as sea.And complete graphite grazing component must include sealed base and graphite-seal ring, sealed base and graphite grazing
Complete graphite grazing component air seal situation is directly affected whether ring matching quality, therefore not only divides valve graphite close bridging type
The roughness and planarity requirements of seal ring end face are high, equally high to the roughness and planarity requirements of sealed base, can match,
To reach optimum efficiency.Although having high-end processing equipment both at home and abroad at present, low roughness and plane can not be all processed
The sealed base of degree can only use rigid grinding-in pedestal in the past, cause eccentric wear because of unbalance stress, flatness can not with take
The formula of connecing divides valve graphite-seal ring end face to match, and released gas rate is overproof when complete graphite grazing component uses, and influences entire unit
Behaviour in service.
Utility model content
In order to overcome above-mentioned existing technological deficiency, the purpose of this utility model is to provide a kind of raising graphite grazings
The roughness and flatness of step end face in pedestal guarantee the efficient of final graphite grazing seat and graphite-seal ring matching precision
Grinding tool.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
The technical program is graphite grazing seat grinding tool, including connecting plate, abrasive disk, guide post and compressed spring；It is described
The fixation hole of suit external impetus equipment is equipped in the middle part of connecting plate；Connecting plate is connected by guide post and compressed spring and abrasive disk elasticity
It connects；The guide post and compressed spring are the multiple groups of setting of being centrosymmetric；The grinding pan bottom is equipped with grinding skewed slot.
As optimization, the grinding agent added holes through bottom, grinding agent added holes upper end opening are provided on the abrasive disk
It is horn-like.
As optimization, the abrasive disk and the graphite grazing pedestal being ground are concentric.
As optimization, the abrasive disk is cast iron quality.
Compared with prior art, the utility model has the beneficial effects that using this grinding tool, platform in graphite grazing pedestal
The roughness and flatness of rank end face greatly improve, and meet layout design technical requirements, to effectively solve graphite grazing pedestal
Interior step end face flatness processing technology problem, the air seal leakage rate after reducing complete graphite grazing component suit, makes
Whole unit performance after assembling gets a promotion.
Detailed description of the invention
The utility model will illustrate by example and with reference to the appended drawing, in which:
Fig. 1 is the main structure schematic diagram of the utility model.
Marked in the figure: connecting plate 1, abrasive disk 2, guide post 3, compressed spring 4, grinding agent added holes 5, fixing screws 6, graphite
Sealed base 7.
Specific embodiment
With reference to the accompanying drawing, the utility model is described in detail.
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Embodiment 1, as shown in fig. 1, the utility model are graphite grazing seat grinding tool, including connecting plate 1, abrasive disk
2, guide post 3 and compressed spring 4；The fixation hole of suit external impetus equipment is equipped in the middle part of the connecting plate 1；Connecting plate 1 is by leading
Column 3 and compressed spring 4 and 2 elastic connection of abrasive disk；The guide post 3 and compressed spring 4 are the multiple groups of setting of being centrosymmetric；Institute
It states 2 bottom of abrasive disk and is equipped with grinding skewed slot；The grinding agent added holes 5 through bottom, grinding agent addition are provided on the abrasive disk 2
5 upper end opening of hole is horn-like；The abrasive disk 2 and the graphite grazing pedestal being ground are concentric；The abrasive disk 2 is cast iron material
Matter.
The grinding of sealed base: 3 bottom of abrasive disk is equipped with grinding skewed slot, roughness Ra0.1, by the connection of grinding tool
Plate 1 is sleeved on machine tool chief axis to be fixed by fixing screws 6, by step centering in the graphite grazing pedestal 7 of required grinding
Center is simultaneously pressed on platen, is started the lathe slow-speed of revolution and is driven grinding tool rotation, abrasive disk 2 is vertical by machine tool chief axis
It is pressed in graphite grazing pedestal 7 on step to movement, abrasive disk 2 is in the case where guide post 3 and compressed spring 4 are acted on to graphite grazing pedestal
Step carries out floating grinding in 7, and grinding agent is added by the grinding agent added holes 5 on abrasive disk 2, in grinding agent added holes
Flare openings structure facilitates quickly adding and prevent grinding agent from pouring down or forth for grinding agent；It is ground by the floating of abrasive disk 2, most
So that the bottom of the steps roughness is reached Ra0.1 eventually, flatness less than 0.0009, and with graphite-seal ring bottom
Matching.
Using this grinding tool, the roughness and flatness of step end face are greatly improved in graphite grazing pedestal, meet figure
Paper technical requirement on design is reduced into effectively solve the problems, such as step end face flatness processing technology in graphite grazing pedestal
Air seal leakage rate after covering graphite grazing component suit, the whole unit performance after making assembling get a promotion.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
