Air inside sealing space realizes the clamping to workpiece to generate internal and external pressure difference.Conversely, if smoothly being inhaled to vacuum
Inflation in disk makes to become zero air pressure or slightly positive air pressure by negative pressure in vacuum chuck, it can unclamp workpiece.
Wherein, Universal vacuum chuck diameter, quantity, the specific determining principle of position are as follows:
(1) determination of sucker diameter
The adjustable post of height in discrete nail bed can be screwed in being separated by 50mm nail hole on pedestal, in order to guarantee that height is adjustable
Space interference does not occur between post and Universal vacuum chuck, sucker lip diameter is necessarily less than 100mm.
(2) determination of sucker layout
The time processing amount very little of sandwich panel Ultra-precision Turning, therefore the operating force generated is also very small, only needs 1
~2 suckers can be completely counterbalanced by.However, to realize ultraprecise milling not only will make the frictional force of sucker offer be greater than milling
Power, it is necessary to which that realizes panel stablizes absorption, guarantees that the deformation of panel in milling process is sufficiently small.
4 points of absorption are respectively adopted to size 400mm × 400mm sandwich surface plate, and (panel quadrangle is respectively set one
Universal vacuum chuck) and 5 points absorption (Universal vacuum chuck is respectively set in panel quadrangle and center) the way of restraint determined
Ultraprecise numerical control processing situation when position is studied (sucker lip diameter is 60mm).Two kinds be fitted after processing is completed
The flatness situation of the way of restraint lower interlayer structural slab is as shown in Figure 7.According to fitting result it follows that if Fig. 7 a, b are when to folder
When layer structure is using 5 suction type constraints, the panel plane degree after processing is evenly distributed, and edge and central area be not bright
Aobvious length travel is poor.If Fig. 7 c, d are when carrying out four point absorption (face plate center is without support) constraint to panel, from fringe region
To center, length travel difference is gradually increased, this is because face plate center region is about when being constrained using 4 suction types
Beam is insufficient, larger displacement is produced under the action of z is to Milling Force, so that generative center region owes to cut phenomenon, when unloading is true
After pneumatics power, it is formed the low distribution situation of intermediate high rim.
According to above-mentioned analysis: when constraining during actual processing panel, it is necessary to assure face plate center and four
Angle is at least arranged a Universal vacuum chuck and adsorbs to it, just can guarantee that panel sufficiently positions and scleronomic constraint, thus real
Existing micro Ultra-precision Turning.When carrying out Ultra-precision Turning positioning to large area panel, need to only be existed using the flexible clamping system
It is reused on large area pedestal using above-mentioned 5 points of absorption the way of restraint as minimum unit.
