Abstract
The utility model discloses a vacuum cup, which comprises a cup body. A concave cavity is formed in the middle of the cup body, an annular edge is connected to the rim of the cup body, and a side on the annular edge facing the side of an opening of the concave cavity is an adsorption plane which is an annular plane and provided with a seal ring. A support rib plate is disposed on the inner wall of the cup body along the direction perpendicular to the adsorption plane, the support rib plate does not extrude relative to the adsorption plane, and a connector communicated with the concave cavity is also arranged at the back of the cup body. When the vacuum cup is utilized to adsorb a workpiece, a workpiece area under the action of differential pressure does not change during vacuum pumping process, an acting force leading the workpiece to bear the differential pressure is big, adsorption is stable, and additional energy consumption caused by addition of the vacuum cup is avoided. Compared with the prior art, the effect of saving energy can be achieved.
Description
Technical field
The utility model relates to a kind of hanger, relates in particular to the bigger vacuum cup of a kind of absorption affinity.
Background technology
Vacuum cup is one of vacuum equipment actuator, during use be adsorbed Work piece sealing and contact, form an airtight air chamber, then with pipeline the rarefaction of air that it is inner of vavuum pump by the connection sealed gas chamber, make the suffered atmospheric pressure of the workpiece one side relative less than the suffered atmospheric pressure of another side with sealed gas chamber, and then by the effect of pressure difference workpiece and vacuum cup are interfixed, have pollution-free, do not hinder workpiece and easy-to-use characteristics.
Vacuum cup of the prior art generally adopts the elastomeric material manufacturing, vacuumizing posterior sucker also closely contacts to the workpiece adhesive under the effect of pressure difference, effect by self reseting elasticity and inside and outside differential pressure, workpiece absorption is fixing, but vacuum cup can make the area of pressure difference effect on the workpiece also diminish after the workpiece adhesive, according to F=PS as can be known, the active force of workpiece institute pressure difference diminishes, be that vacuum cup is insecure to the absorption of workpiece, cause obscission easily, and set up a plurality of vacuum cups, need expend the more energy.
Therefore, in order to guarantee the active force of the pressure reduction that workpiece is suffered, energy savings needs a kind of vacuum cup that can form enough big differential pressure action face with workpiece.
The utility model content
In view of this, the utility model provides a kind of vacuum cup, can keep the area of workpiece pressure difference effect not change in vacuum, so the active force of workpiece pressure difference is bigger, and absorption is firm.
Vacuum cup of the present utility model, comprise the sucker body, the middle part of described sucker body forms cavity, what be connected with described sucker body outer has a ring limit, one side towards the cavity open side on the ring limit is an adsorption plane, and described adsorption plane is planar annular and is provided with sealing ring that the inwall that is positioned at the sucker body is provided with the support floor along the direction perpendicular to adsorption plane, described support floor does not protrude in adsorption plane, and the back of described sucker body also is provided with the joint that is communicated with cavity.
Further, the rounded recessed plate-like of described sucker body;
Further, described support floor radially is provided with along the sucker body, and is equal with the adsorption plane on ring limit, and along circumferentially evenly distributing.
Further, the inboard sealing strip that is provided with of going back one of described sealing ring, sealing ring is adhered to ring surface, limit, and sealing strip is adhered to and supports the floor surface.
The beneficial effects of the utility model are: use vacuum cup absorption workpiece of the present utility model, in vacuum, can keep the area of workpiece pressure difference effect not change, make the active force of workpiece pressure difference bigger, absorption is firm, avoided setting up the additional energy source consumption that vacuum cup causes, compared with prior art, can reach the effect of energy savings.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a front view of the present utility model;
Fig. 2 is a upward view of the present utility model.
The specific embodiment
Fig. 1 is a front view of the present utility model, Fig. 2 is a upward view of the present utility model, as shown in the figure: the vacuum cup of present embodiment, comprise sucker body 1, the middle part of described sucker body 1 forms cavity, be connected with described sucker body 1 outer have the ring limit 2, one side towards the cavity open side on the ring limit 2 is an adsorption plane, described adsorption plane is planar annular and is provided with sealing ring 21, the inwall that is positioned at sucker body 1 is provided with along the direction perpendicular to adsorption plane and supports floor 11, described support floor 11 does not protrude in adsorption plane, the back of described sucker body 1 also is provided with the joint 12 that is communicated with cavity, when the vacuum cup of present embodiment adsorbs workpiece, in vacuum, support 11 pairs of sucker bodies 1 of floor and workpiece and play a supporting role, can avoid sucker body 1 to workpiece adhesive and contact with it, keep the area of workpiece pressure difference effect not change, make the active force of workpiece pressure difference bigger, absorption is firm.
In the present embodiment, described sucker body 1 rounded recessed plate-like, rational in infrastructure.
In the present embodiment, described support floor 11 radially is provided with along sucker body 1, and is equal with the adsorption plane on ring limit 2, and along circumferentially evenly distributing, makes the suffered support force of sucker body more even, and stressed effect is good, and production and processing easily.
In the present embodiment, described sealing ring 21 inboard also one be provided with sealing strip 13, sealing ring 21 is adhered to ring 2 surfaces, limit, sealing strip 13 is adhered to and supports floor 11 surfaces, be used for the poor slightly thin-walled shape workpiece of rigidity, can effectively prevent to deform under the effect of workpiece differential pressure action power.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
