Description
Technical field
The utility model technical field is about sucker structure, is that one kind is inhaled in sucker circumference equipped with multistage in more detail
The sucker structure in attached portion.
Background technique
The vacuum chuck used in daily life, the mode for excluding air in sucker can keep its flat by pressing sucker
Or manual operation sucker on suction unit and reach, this kind of suckers must be dependent on significantly it is flat deformation keep it almost complete
The Contact-sorption face of area, and be attached on adsorption plane by the antiskid property of material and stickiness, therefore this kind of suckers can only
The adsorption planes such as flat, smooth glass surface, mirror surface, ceramic tile are adsorbed on, slightly coarse surface cannot then be used.In addition,
This kind of suckers for the adhesive force of adsorption plane be from center to circumference decrescence, in other words, the adhesive force of sucker circumferential location
Most weak, the pressure of outside air is easy to break through circumferential location and relieve the vacuum adsorption force of sucker, and sucker is made to fall off.Again
The area of person, this kind of suckers are smaller, therefore adsorption area is small, and adsorption capacity is weaker, and because ambient temperature and humidity variation and
The load-bearing capacity of the influence of the factors such as the elastic restoring force of sucker itself, sucker is weaker, and is easier to fall off.
Utility model content
Technical problem underlying to be solved in the utility model is, overcomes drawbacks described above of the existing technology, and mentions
For a kind of multi-stage absorption vacuum chuck, adsorption capacity can be enhanced, load-bearing capacity, the long period can not fall off, even may be used at
Surface is not the adsorption plane of completely smooth planar.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of multi-stage absorption vacuum chuck, comprising: a core portion and the disk prolonged from the outside oblique expansion of the core portion circumference are oblique
Portion；The circumference bottom surface of the disk inclined portion is equipped with the multi-stage absorption portion of annular, the multi-stage absorption portion include several concentric rings around absorption
Rank, several absorption ranks have difference in height, and the height near the absorption rank in the core portion is highest, remaining absorption rank
Height sequentially to the circumferencial direction of the disk inclined portion reduce.
Preferably, several absorption ranks have width poor, the absorption rank width near the core portion is minimum, remaining
The width of the absorption rank is sequentially incremented by.
Preferably, the multi-stage absorption portion is located at the position of the outer rim to outer 1/5th of the disk inclined portion.
The effect of the utility model:
Multi-stage absorption portion increases the adhesive force of vacuum chuck circumferential location, and external air pressure is not easy to break through circumferential location
Multi-stage absorption portion, it is ensured that gas leakage will not occur for sucker.
Multi-stage absorption portion guarantees the laminating degree of sucker and object, and it is empty that every grade of absorption rank can respectively form closed sealing
Between, when being bonded with object, if causing wherein primary adsorption rank failure, other grades due to protrusion or pit etc.
Absorption rank can also play sealing function, therefore improve sucker to rough surface or have the object of the defects of microprotrusion, pit
The adsorption capacity of body.
In conclusion multi-stage absorption portion strengthens the compactness of sucker and adsorption plane, adsorption capacity, weight bearing ability, energy are promoted
Long period does not fall off, may be used at the adsorption plane that surface is not completely smooth planar.
The utility model has the beneficial effects that it can enhance adsorption capacity, load-bearing capacity, can not fall off, even the long period
It may be used at the adsorption plane that surface is not completely smooth planar.

Specific embodiment
For ease of illustration of the utility model central idea represented in above-mentioned one column of new content, hereby with specific implementation
Example expression.In embodiment it is various difference objects be in be suitable for explanation ratio, size, deflection or displacement and describe, rather than
It is drawn in the ratio of actual component, conjunction is first chatted bright.
Fig. 1 describes the composed structure of the vacuum chuck 20 of vacuum suction apparatus 10 and the utility model, as known,
The vacuum suction apparatus 10 is manually operated, and the air in vacuum chuck 20 can be discharged, and make inside vacuum chuck 20 into vacuum state
And adsorb a solid face.The vacuum chuck 20 is using tool flexible deformation and returns the material production of ability, and material includes but unlimited
In rubber, silicon rubber, polyurethane.
Fig. 1 to Fig. 4, the vacuum chuck 20 are collar plate shape structure, including core portion 21 and oblique outward from 21 circumference of core portion
The disk inclined portion 22 prolonged to expansion.The vacuum chuck 20 is equipped with the multi-stage absorption portion 30 of annular dentation in the circumference bottom surface of disk inclined portion 22,
The multi-stage absorption portion 30 is located at the position of the outer rim to outer 1/5th of the disk inclined portion 22.The multi-stage absorption portion 30 includes concentric ring
Around three absorption ranks 31,32,33, be defined herein as the first absorption rank 31, the second absorption rank 32, third adsorbs rank 33.This three
A absorption rank has difference in height, and the third absorption rank 33 near core portion 21 is higher than the second absorption rank 32, the second absorption rank 32
Rank 33 is adsorbed higher than near the first of circumference.Three absorption ranks have width poor, and the width of the first absorption rank 31 is greater than second
Rank 32 is adsorbed, the width of the second absorption rank 32 is greater than third and adsorbs rank 33.
Such as Fig. 5 to Fig. 8, the vacuum suction apparatus 10 is manually operated, and the air in vacuum chuck 20 can be discharged, and make vacuum
At vacuum state inside sucker 20, the slightly flat deformation of the vacuum chuck 20 adsorbs a solid face with the multi-stage absorption portion 30.It is more
Suction adsorption section 30 is stage absorption, is first adsorbed in solid face with the first absorption rank 31, is next sequentially the second absorption rank 32
Rank 33 is adsorbed with third.
Every grade of absorption rank 31,32,33 can respectively form closed vacuum sealing space, and every grade of absorption rank 31,32,33 is equal
It is bonded with solid face adherence, keeps prolonged adhesive force, increase the adhesive force of 20 circumferential location of vacuum chuck, it is ensured that vacuum is inhaled
Gas leakage will not occur for disk 20, improve the most weak problem of traditional vacuum sucker circumferential part adsorption capacity.Due to the utility model vacuum
Sucker 20 be not it is comprehensive fit in solid face, but solid face is attached to multi-stage absorption portion 30, therefore the solid face removes
It is except smooth planar face, if concave-convex non-fully smooth planar face is also applicable slightly.In addition, if wherein primary adsorption
Rank failure, the absorption rank of other grades still can play sealing function.
Release 20 vacuum adsorption state of the utility model vacuum chuck mode, be with manual drawing on vacuum chuck 20
Protrusion 23, the inclined power of previous upper drawing was bestowed on vacuum chuck 20, the multi-stage absorption portion 30 and real is released in a manner of external force
The attachment of dignity can remove vacuum chuck 20.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation, it is made by the above technical examples according to the technical essence of the present invention it is any it is simple modification, equivalent variations with
Modification, is still within the scope of the technical solutions of the present invention.
