Description
Technical field
This utility model relates to a workpiece milling apparatus, and a kind of sealing surface to valve grinds
The milling apparatus of mill.
Background technology
The now hard valve sealed, it will usually be ground on the sealing surface of valve, with the sealing surface of valve
Smooth, smooth, to ensure the sealing effectiveness of valve.The grinding of existing valve sealing face mainly uses two
The mode of kind is carried out, and one mode is that valve maintains static, and grinds bistrique and contacts with the sealing surface of valve,
And constantly carry out activity so that it is the sealing surface of valve is ground；Another way is that valve is placed
In abrasive disk, whole abrasive disk is rotating, and utilizes abrasive disk and rotating against of valve to realize grinding
Mill.But, use the first lapping mode to be difficult to control the levelness of valve sealing face, grind requirement
Precision is the highest, easily causes lapping efficiency relatively low；Though using the second lapping mode to overcome first
Plant lapping mode and cause, because grinding precision prescribed height, the problem that working (machining) efficiency is low, but valve depends merely on abrasive disk
Rotation realize grind if grinding effect poor, and grind time because of valve always around abrasive disk make
Rotary motion, utilizes the self gravitation of valve, and gravity is downward, makes the valve can constantly crush and grind dish
Interior abrasive pastes, make abrasive pastes lose in a large number, and then reduce grinding effect further.
In view of this, existing drawbacks described above is furtherd investigate by the present inventor again, then produces in this case
Raw.

Reversion make movable block 5 move down, move down, along with movable block 5, the horizontal stroke made on movable block 5
Sleeping vibration strengthens block 6 to be affected progressively in just upwards pulling by stop collar 7, finally makes vibration strengthen block 6
Vibration enhancing block, again in upright state, so, when vibrating motor 4 rotates forward again, also can make
Vibration strengthens block 6 setting rising and finally keeps flat accumbency setting, then, the positive and negative of vibrating motor 4 is revolved repeatedly
Turn, it is possible to when making valve do vibration fricting movement in abrasive disk, moreover it is possible to do the most inside, outside
Sliding friction campaign.Compared with prior art, it can make valve in abrasive disk except making vibration friction
Motion is outer makees the most inside, outside sliding friction campaign the most simultaneously, make valve obtain vibration friction with
Sliding friction, significantly improves integral grinding speed, makes the grinding effect of valve sealing face significantly carry
Height, thus grinding-in of valve quality is relatively stable reliably, meanwhile, by anti-in abrasive disk of valve
The most outside multiple sliding friction campaign, make valve will not constantly abrasive pastes in crush and grind dish,
Greatly reduce the loss of abrasive pastes, be effectively guaranteed grinding effect.
In this utility model, the free end end of the output shaft 41 of this vibrating motor 4 has accumbency,
And with the spacer pin 8 that the output shaft 41 of vibrating motor 4 is arranged in a mutually vertical manner, utilize this spacer pin 8 can
Prevent movable block 5 from skidding off outside output shaft 41.
In this utility model, the low bottom-disc of this vibration frame 22 is convexly equipped with downwards closed-loop shaped bulge loop 222,
The upper end of mounting post 221 is in closed-loop shaped bulge loop 222, and the end, upper end of vibrating spring 3 is in be closed
In annular convex ring 222, utilize this closed-loop shaped bulge loop 222 can make the installation more spring of vibrating spring 3.
