Abstract
The utility model belongs to flat grinding device, and in particular to a kind of double eccentric automatic 8 word flat grinding devices of heavy-caliber gate valve flashboard.A kind of double eccentric automatic 8 word flat grinding devices of heavy-caliber gate valve flashboard, including motor-driven mill, planar support nog plate, flashboard, abrasive sand, eccentric abrasive sheet, eccentric milling bar, the planar support nog plate are arranged in motor-driven mill, and flashboard and abrasive sand are arranged on planar support nog plate, eccentric abrasive sheet is set in abrasive sand, eccentric milling bar is set on eccentric abrasive sheet.The effect of the utility model is: using small 8 word polishing principle, there are two distinguishing features: the 1. labyrinth seal tracks formd；2. the abrasive sand of abrasive sheet is constantly in uniformly distributed grinding, while improving the service life of abrasive sand due to the eccentric effect around axis turn and rotation of abrasive sheet.This two o'clock is effectively controlled the flatness of flashboard for sluice valve, reduces the leakage rate of valve, is to be very suitable to the grinding of heavy-caliber gate valve flashboard.
Description
Technical field
The utility model belongs to flat grinding device, and in particular to a kind of double eccentric automatic 8 word planes of heavy-caliber gate valve flashboard
Grinding device.
Background technique
The center Plane of rotation grinding technique of existing flashboard is to belong to circumference grinding.Firstly, its track is that rule is concentric
Circle.Under microcosmic, sealing surface quality is mainly the influence of the value of wave crest and the degree size of surface deviation, when two sealing surfaces are applied
Plus-pressure makes wave crest generation compressive deformation form pore.Hydrone is by increasing movement resistance when labyrinth channel under microcosmic
Power is to play sealing function, but this is not best lapping mode.Firstly, because labyrinth is logical under the sealing surface of unit width
Road is more complicated, and sealing effect is better；Secondly, the abrasive sand of abrasive sheet is constantly in same position grinding, it is longer using the time
Afterwards, it may appear that groove is unfavorable for grinding.
Utility model content
The utility model in view of the drawbacks of the prior art, grind by the double eccentric automatic 8 word planes for providing a kind of heavy-caliber gate valve flashboard
Mill apparatus.
The technical solution of the utility model is: a kind of double eccentric automatic 8 word flat grinding devices of heavy-caliber gate valve flashboard, including
Motor-driven mill, planar support nog plate, flashboard, abrasive sand, eccentric abrasive sheet, eccentric milling bar, the planar support nog plate
It is arranged in motor-driven mill, flashboard and abrasive sand is set on planar support nog plate, eccentric abrasive sheet is set in abrasive sand,
Eccentric milling bar is set on eccentric abrasive sheet.
Double eccentric automatic 8 word flat grinding devices of a kind of heavy-caliber gate valve flashboard as described above, wherein ground in bias
Eccentric distance rotating hole is arranged in plate centre.
Double eccentric automatic 8 word flat grinding devices of a kind of heavy-caliber gate valve flashboard as described above, wherein described is inclined
Heart milling bar is the milling bar with eccentric distance.
The effect of the utility model is: using small 8 word polishing principle there are two distinguishing feature: 1. form Fig. 6 labyrinth it is close
Seal track；2. the abrasive sand of abrasive sheet is constantly in uniformly distributed grinding, together due to the eccentric effect around axis turn and rotation of abrasive sheet
When improve service life of abrasive sand.This two o'clock is effectively controlled the flatness of flashboard for sluice valve, reduces the leakage rate of valve, is
It is very suitable to the grinding of heavy-caliber gate valve flashboard.

Specific embodiment
As shown in Figure 1, a kind of double eccentric automatic 8 word flat grinding devices of heavy-caliber gate valve flashboard, mainly include electronic
Grinder 1, planar support nog plate 2, flashboard 3, abrasive sand 4, eccentric abrasive sheet 5, eccentric milling bar 6.
At abrasive sheet center, processing has eccentric distance rotating hole；
Processing has the rotary shaft of eccentric distance.
Component (clearance fit) is mounted in motor-driven mill, by the shaft low speed of motor-driven mill 30-60r/min
Eccentric milling bar is rotated, eccentric milling bar generates thrust and pushes eccentric abrasive sheet, forms eccentric rotational motion, and due to abrasive sheet
Be eccentrically formed centrifugal force, abrasive sheet, which starts simultaneously at, to be generated rotation and forms rotation track, and rotation and revolution grinding track are more multiple
It is miscellaneous, effectively raise the sealing performance of flashboard.
Above-mentioned specific embodiment is used to illustrate this patent, rather than limits this patent, in this patent
In spirit and scope of protection of the claims, to any modifications and changes that this patent is made, the protection model of this patent is both fallen within
It encloses.
