Abstract
The utility model discloses a kind of plane sealing structures of actuator cylinder cap and cylinder body, including cylinder body, the cylinder body side is equipped with cylinder cap, the cylinder cap side is provided with groove, the trench interiors are equipped with O-ring seals, the O-ring seals include metal gasket, interior reinforcing ring and outer annular-stiffer, and interior reinforcing ring is fixedly connected on inside the metal gasket.There are the risks of leakage failure for traditional macropore sealing, the utility model is then that sealing station is transferred in plane, so that sealing effect is more preferably, cylinder cover structure optimization is shortened with the effective length of macropore cooperation, cylinder cap weight can be mitigated, reduce the cost of raw material, the O-ring groove rheo-die-casting molding of flat seal, without being machined out, production efficiency is greatly improved, cost is reduced.Pass through the outer annular-stiffer on the outside of the interior reinforcing ring and O-ring seals on the inside of O-ring seals so that O-ring seals are more wear-resisting, extend the service life of O-ring seals.
Description
Technical field
The utility model is related to machine components technical field, the flat seal knot of specially a kind of actuator cylinder cap and cylinder body
Structure.
Background technology
Gasket is the mechanical seal between two objects, usually to prevent from being under pressure between two objects, burn into and
Pipeline expands with heat and contract with cold leakage naturally.Since machining surface can not possibly be perfect, scrambling can be filled up using gasket.Pad
Piece is usually made of flaky material, such as packing paper, rubber, silicon rubber, metal, cork, felt, neoprene, nitrile rubber, glass
Fiber or plastic polymer（Such as polytetrafluoroethylene (PTFE)）.The gasket of specific application may contain asbestos.Washer is thin plate（Usually circle
Type）A loophole（Usually in centre）Typically it is used for the load thread fastener of distribution.Other purposes are as interval, bullet
Spring（Belleville gasket, wave gasket）, wear-resistant pad, pre-display device, locking device.Rubber washer is also used in tap（Valve）
With the liquid or gas of cut-out flowing.Rubber or silicon spacer can also be used, to reduce the vibration of fan.Usual gasket outer diameter is interior
Twice or so of diameter.
Circle is lost in processing cylinder body macropore circularity unavoidably, and cylinder diameter is bigger, and this phenomenon is more serious, and the sealing of traditional macropore is deposited
In the risk of leakage failure, so providing the plane sealing structure of a kind of actuator cylinder cap and cylinder body to solve asking for above-mentioned appearance
Topic very it is necessary to.
Utility model content
It is above-mentioned to solve the purpose of this utility model is to provide a kind of plane sealing structure of actuator cylinder cap and cylinder body
The problem of being proposed in background technology.
To achieve the above object, the utility model provides the following technical solutions：A kind of plane of actuator cylinder cap and cylinder body
Sealing structure, including cylinder body, the cylinder body side are equipped with cylinder cap, and the cylinder cap side is provided with groove, and the trench interiors are set
It includes metal gasket, interior reinforcing ring and outer annular-stiffer to have O-ring seals, the O-ring seals, and the metal gasket inside is solid
Surely it is connected to interior reinforcing ring, outer annular-stiffer is fixedly connected on the outside of the metal gasket.
Preferably, the O-ring seals both sides are circular arc chamfering.
Preferably, it is provided with card slot on the inside of the end cap, the card slot side is equipped with connector.
Preferably, the groove is loop configuration.
Compared with prior art, the utility model has the beneficial effects that：A kind of actuator cylinder cap of the utility model and cylinder body
Plane sealing structure, structure novel, traditional macropore seal there are the risk of leakage failure, which is then sealing position
It sets and is transferred in plane so that sealing effect more preferably, shorten with the effective length of macropore cooperation, can mitigate by cylinder cover structure optimization
Cylinder cap weight, reduces the cost of raw material, and the O-ring groove rheo-die-casting molding of flat seal without being machined out, substantially carries
High efficiency reduces cost.By the outer annular-stiffer on the outside of the interior reinforcing ring and O-ring seals on the inside of O-ring seals,
So that O-ring seals are more wear-resisting, extend the service life of O-ring seals.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model O-ring seals main structure diagram；
Fig. 3 is the utility model O-ring seals overlooking structure diagram；
Fig. 4 is the utility model part A partial enlargement structural representation.
In figure：1 cylinder body, 2 cylinder caps, 3 grooves, 4 O-ring seals, 5 metal gaskets, reinforcing ring, 7 outer annular-stiffers, 8 circles in 6
Arc chamfering, 9 connectors, 10 card slots.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
- 4 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of flat seal of actuator cylinder cap and cylinder body
Structure, including cylinder body 1,1 side of the cylinder body are equipped with cylinder cap 2, and 2 side of the cylinder cap is provided with groove 3, inside the groove 3
Equipped with O-ring seals 4, the O-ring seals 4 include metal gasket 5, interior reinforcing ring 6 and outer annular-stiffer 7, the metal gasket
Interior reinforcing ring 6 is fixedly connected on inside piece 5,5 outside of the metal gasket is fixedly connected with outer annular-stiffer 7.
4 both sides of the O-ring seals are circular arc chamfering 8.2 inside of the end cap is provided with card slot 10, the card slot 10 1
Side is equipped with connector 9.The groove 3 is loop configuration.
Operation principle：The utility model structure novel, for the sealing of traditional macropore there are the risk of leakage failure, the practicality is new
Type is then that sealing station is transferred in plane so that more preferably, cylinder cover structure optimizes sealing effect, the effective length with macropore cooperation
Shorten, cylinder cap weight can be mitigated, reduces the cost of raw material, the O-ring groove rheo-die-casting molding of flat seal, without the machine of progress
Processing, greatly improves production efficiency, reduces cost.Outside by the interior reinforcing ring 6 and O-ring seals 4 of 4 inside of O-ring seals
The outer annular-stiffer 7 of side so that O-ring seals 4 are more wear-resisting, extend the service life of O-ring seals 4.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
