Embodiment
Below in conjunction with accompanying drawing, for example the present invention is described in more detail:
In conjunction with Fig. 1～6, the object of the invention is to provide a kind of simple in structure, reliable operation, the cellular vacuum chuck that still can normally work the in the situation that of existing the defects such as local cracks, aperture to cause local gas leakage at workpiece.The rubber membrane of this sucker has completely cut off dust etc. and has entered vacuum system, and without independent filtration system, while not working, sucker mouth is smooth smooth, and convenient cleaning, so sucker can be worked in the rugged environments such as many dust, mashing.
The cellular vacuum chuck of the present invention comprises: rubber membrane, macroporous plate, aperture plate and sucker shell.Rubber membrane is flexible high-elastic all thick rubber membranes, and the details of macroporous plate, aperture plate and sucker shell is as follows:
Macroporous plate: macroporous plate integral body is in the form of annular discs, there is a solid endless belt disk outer end.Endless belt is uniformly distributed through hole with interior disk body, through hole be shaped as regular hexagon.The thickness of macroporous plate equals the external radius of a circle of regular hexagon.
Aperture plate: aperture plate is discoideus, aperture plate external diameter is slightly less than sucker shell internal diameter.Intensive a lot of spileholes that distribute equably on aperture plate, the diameter of pore equals the thickness before rubber pattern distortion.
Sucker shell: sucker shell integral body is hemispherical.Little opening end is the pipe to give prominence to, and pipe end is flange, 8 bolts hole of circumference uniform distribution on flange.
Aperture plate 3 is welded on macroporous plate 2, and macroporous plate 2 is welded on sucker shell 4 again.During welding, guarantee that aperture plate 3 is in sucker shell one side.Rubber membrane 1 directly sticks on macroporous plate.Sucker shell 4 is partly connected with vacuum pump by flange.
While not working, rubber membrane 1 is reset condition, not distortion.Sucker is pressed close to behind the surface of the object that will adsorb, and vacuum pump is extracted the air of sucker shell 4 inside out.Because sucker is when being attached to body surface, between rubber membrane 1 and body surface, can there is minimum gas, due to the effect of pressure reduction, there is tensile buckling in rubber membrane 1, and is out of shape along the regular hexagon through hole of macroporous plate 2.After rubber membrane 1 contact aperture plate 3, because the size of pore approaches the thickness of rubber membrane 1, what now rubber membrane occurred is shear deformation, underpressure so that rubber membrane 1 deform, so rubber membrane 1 stops distortion.Low pressure between dependence rubber membrane 1 and body surface and the effect of atmospheric pressure, sucker is mentioned object.
When the surface of object exists the defects such as crack, while causing local gas leakage.Rubber membrane in the regular hexagon through hole of gas leakage part increases at the side air pressure contacting with body surface, so rubber membrane 1 will further be out of shape.But due to stopping of aperture plate 3, the shearing strain quantity of rubber membrane 1 is very little, the volume of sucker shell 4 cavitys is out of shape volume much larger than this, thus the air pressure in sucker shell 4 do not change, thereby the air pressure of the regular hexagon through hole of air tight part is constant.In sum, local gas leakage can not cause sucker shell 4 internal air pressures acutely to decline, and has ensured that in local gas leakage situation, sucker still can work on.
The cellular vacuum chuck of the present invention, comprises rubber membrane 1, macroporous plate 2, aperture plate 3 and sucker shell 4.Aperture plate 3 is welded on macroporous plate 2, and macroporous plate 2 is welded on sucker shell 4 again.Rubber membrane 1 directly sticks on macroporous plate 2.Whole sucker is connected with vaccum pump unit by the flange of sucker shell 4.
Macroporous plate 2 is whole in the form of annular discs, and there is a solid endless belt disk outer end.Endless belt is uniformly distributed through hole with interior disk body, through hole be shaped as regular hexagon.
Aperture plate 3 is discoideus, and aperture plate 3 external diameters are slightly less than sucker shell 4 internal diameters.Intensive a lot of spileholes that distribute equably on aperture plate 3, the diameter of pore equals the thickness before rubber pattern 1 distortion.
On macroporous plate 2, be uniformly distributed regular hexagon through hole, by with the coordinating of rubber membrane 1, a large sucker is divided into a lot of uniform small suckers; Intensive uniform spilehole on aperture plate 3 can stop by air the further distortion of rubber membrane 1 simultaneously.
After the air of sucker shell 4 inside is drawn out of, because sucker is when being attached to body surface, between rubber membrane 1 and body surface, can have minimum gas, under the effect of pressure reduction, rubber membrane 1 is along the regular hexagon through hole generation tensile buckling of macroporous plate 2.After rubber membrane 1 contact aperture plate 3, change shear deformation into, underpressure is so that rubber membrane 1 deforms, and rubber membrane 1 stops distortion.Formation low pressure between rubber membrane 1 and body surface, under barometric pressure effect, sucker is mentioned object.
When on macroporous plate 2, in certain regular hexagon through hole, rubber membrane internal air pressure increases (being equivalent to local gas leakage), this part rubber membrane 1 has the trend of distortion, but due to stopping of aperture plate 3, the shearing strain quantity of rubber membrane 1 is very little, air pressure in sucker shell 4 does not change, thereby the air pressure of the regular hexagon through hole of air tight part is constant.
Under the cooperation of rubber membrane 1, macroporous plate 2 and aperture plate 3, make local gas leakage can not cause sucker shell 4 internal air pressures to decline, ensured that in local gas leakage situation, sucker still can work on.
Rubber membrane 1 has completely cut off dust, water slurry etc. and has entered vacuum system, and makes the easy to clean of sucker mouth.
Aperture plate 3 is welded on macroporous plate 2, and macroporous plate 2 is welded on sucker shell 4 again.During welding, guarantee that aperture plate 3 is in sucker shell 4 the same sides.Rubber pattern 1 directly sticks on macroporous plate 2.Sucker shell 4 is partly connected with vacuum pump by flange.
For carrying out brief calculation explanation, establishing macroporous plate 2 regular hexagon hole exradius is R, and it is t that rubber membrane 1 is not out of shape thickness, and direct stress allowable is σ
maxfrom the structural feature of cellular vacuum chuck, the thickness of macroporous plate 2 is about h=R, and on aperture plate 3, hole diameter is t.
While not working, rubber membrane 1 is reset condition, not distortion.Sucker is pressed close to behind the surface of the object that will adsorb, and vacuum pump is extracted the air of sucker shell 3 inside out.Because sucker is when being attached to body surface, between rubber membrane 1 and body surface, can there is minimum gas, after the gas of sucker shell 3 is drawn out of, effect at pressure reduction, rubber membrane 1 deforms, and is out of shape along the regular hexagon through hole of macroporous plate 2, and deformation as shown in Figure 5.Due to the width in the regular hexagon hole thickness much larger than rubber membrane 1, there is larger distortion in rubber membrane 1, and deformation type is common tensile buckling.For the rubber membrane in tensile buckling in regular hexagon through hole, after distortion, be almost full of regular hexagon through hole.As shown in Figure 6, after rubber membrane 1 contact aperture plate 3, because the size of pore approaches the thickness of rubber membrane 1, what now rubber membrane occurred is shear deformation, underpressure so that rubber membrane 1 continue to deform, so rubber membrane 1 stops distortion.Low pressure between sucker dependence rubber membrane 1 and body surface and the effect of atmospheric pressure are mentioned object as common sucker.
When the surface of object exists the defects such as local cracks, while producing local gas leakage.Rubber membrane in the regular hexagon through hole of gas leakage part can increase by air pressure in the side contacting with body surface, until increase to barometric pressure, rubber both sides differential pressure of membrane is a barometric pressure to the maximum, so rubber membrane will further be out of shape.As shown in Figure 6, for the rubber in shear deformation, the shearing stress bearing is:
Because rubber shearing stress is only pressed direct stress, therefore the shearing stress τ that rubber can bear
max=σ
max, the minimum direct stress 2MPa of the softest natural rubber left and right, is far longer than 0.025MPa.Therefore rubber can sustain pressure reduction during gas leakage, and the distortion producing is very little.
Therefore due to the stopping of aperture plate, the shearing strain quantity of rubber membrane is very little, and the volume of sucker shell 4 cavitys is out of shape volume much larger than this, thus the air pressure in sucker shell 4 do not change, thereby the air pressure of the regular hexagon through hole of air tight part is constant.In sum, local gas leakage can not cause sucker shell internal air pressure to decline, and has ensured that in local gas leakage situation, sucker still can work on.In addition, the rubber membrane of this sucker has completely cut off dust etc. and has entered vacuum system, and without independent filtration system, while not working, sucker mouth is smooth smooth, and convenient cleaning, so sucker can be worked in the rugged environments such as many dust, mashing.
