Embodiment two:
Figure 14 and Figure 15 is a kind of work shape of the embodiment two of numerical control high-precision planetary mechanism grinder of the utility model
State figure；As shown in figure 14, wherein using appended drawing reference corresponding with embodiment one with component identical or corresponding in embodiment one,
For simplicity, hereafter only describe with the distinctive points of embodiment one, the embodiment two it is different from embodiment one shown in FIG. 1 it
Be in:
As shown in Figure 14 and Figure 15, for grinding turntable 32 and rotate clockwise, revolved clockwise in grinding turntable 32
When turning, the lapping using star lapping machine component 42 on turntable 32 is ground while carrying out the rotation opposite with grinding 32 direction of rotation of turntable,
At this time what is different from the first embodiment is that the fixation of orientation assemblies 41 does not shift, valve plate 10 carries out the grinding of class " 8 " word and mentions, at this point,
Due to having lacked supply of the orientation assemblies 41 in transverse movement, the path that valve plate 10 is walked on grinding turntable 32 is class " 8 "
Font.
The course of work:
As shown in Figure 11, Figure 12 and Figure 13, for grinding turntable 32 and rotate clockwise, carried out in grinding turntable 32 suitable
When hour hands rotate, the lapping using star lapping machine component 42 ground on turntable 32 is carrying out the rotation opposite with grinding 32 direction of rotation of turntable
While, and be oriented to by orientation assemblies 41, it is deviated along with the grinding consistent direction in 32 direction of rotation of turntable, is valve plate
10 carry out the supply that the grinding of " 8 " word improves transverse movement, and during offset, the valve plate 10 in lapping using star lapping machine component 42 is ground
The centrifugal force of turntable 32 is close to contradict with lapping using star lapping machine component 42, and frictional force of the valve plate 10 by lapping using star lapping machine component 42 carries out
With the consistent rotation in 42 direction of rotation of lapping using star lapping machine component, as shown in figure 12, the A point on valve plate 10 is in planet grinding assembly 42
During being deviated, always happen change, realizes the forming of figure of eight track half of the A point in migration process, later
Actuator 511 is controlled by numerical control control cabinet to reversely rotate, and makes the other half of the A point complete dish figure of eight track on valve plate 10.
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.
