The air cylinder rear cover buffering and sealing structure is convenient to assemble and good in reliability.
Description
Technical field
The utility model relates to cylinder field, especially relates to a kind of cylinder back cover cushion seal structure.
Background technique
Conventional cylinder is mainly comprised of structures such as cylinder body, protecgulum, bonnet, piston and piston rod, Sealing and shock absorbers.The Sealing of cylinder mainly contains the stationary seal ring of piston packing ring, rod seal ring, protecgulum and bonnet and cylinder body joint; The shock absorber of cylinder is often referred to the rubber sheet gasket between piston and protecgulum, bonnet.This structure of conventional cylinder, because part is more, the warehousing management cost of the manufacture cost of whole product, component is higher, and the assembly process of product is more loaded down with trivial details, and the time cost of single finished product is also higher.
Chinese patent notice of authorization number: CN202203210U, April 25 2012 notice of authorization day, disclose and the utility model discloses a kind of cylinder of freely installing, comprise front end housing, bonnet, piston rod, piston is located in the chamber of front end housing and bonnet composition, piston rod one end is connected with piston, stretch out by front end housing piston rod one end, two O type circles and cushion pad are installed between piston and piston rod, and described piston rod one end is stretched out end by front end housing nut is installed, and is provided with dust cap and compound sleeve device on described piston rod.This cylinder is when assembling, and its assemble flow is generally that O type circle is put the oil, the assembling of O type circle and cushion pad assemble this 3 step, and more loaded down with trivial details, in addition because the component of product are more, the probability of product failure just increases greatly, and reliability is lower.
Model utility content
The utility model is in order to overcome the deficiency that in prior art, the assembling of cylinder back cover cushion seal parts is loaded down with trivial details, reliability is not good, a kind of easy to assembly, the good cylinder back cover cushion seal of reliability structure to be provided.
To achieve these goals, the utility model is by the following technical solutions:
A kind of cylinder back cover cushion seal structure of the present utility model, comprise circular body, the edge of described body is bent to form sealed department towards the direction perpendicular to body surface, the edge of described sealed department is provided with the seal ring that protrudes from sealed department outer surface, and described body is provided with the buffering of body integrative-structure protruding away from the surface of sealed department.After installing, seal ring between bonnet and cylinder body, buffering projection between piston and bonnet to prevent that piston from directly contacting with bonnet, integrate sealing and pooling feature, more convenient and quicker during assembling, efficiency of assembling is improved, and cost of production is minimized.In addition, when piston action is when buffering is protruding, body and sealed department can provide better support to cushioning projection, prevent from cushioning projection and are offset, and reduce the protruding wearing and tearing of buffering, and overall structure stability is better.Simultaneous buffering projection expands outwardly sealed department for the active force of sealed department, makes to compress between seal ring and cylinder body, and sealability further improves.
As preferably, ringwise and coaxially arranged with body, the buffering projection relatively distance at body center is less than the distance at the relative body of sealed department center to described buffering projection.Like this, when buffering projection is subject to the impact from piston, active force evenly can be passed on body center and sealed department, reduce moving radially of buffering projection, the stability while improving buffering.
As preferably, described body is provided with positioning convex towards the centre of surface of sealed department, and it is conical that described positioning convex is.Positioning convex is set and can guarantees reliability of positioning between body and bonnet.
As preferably, in described body, a side at mind-set sealed department place is protruded and is formed centralized positioning face.Centralized positioning face can play positioning action, has strengthened in addition for the protruding support effect of buffering the stability while having improved buffering.
As preferably, the internal surface of described sealed department is provided with the clamping ring corresponding with seal ring position, between described clamping ring, sealed department and body, forms draw-in groove.By clamping ring, can easily body be arranged on bonnet, improve efficiency of assembling.
As preferably, described body adopts elastic material to make.
Therefore, the utlity model has following beneficial effect: (1) is easy to assembly quick, and efficiency of assembling promotes, and has reduced cost of production; (2) it is more outstanding that sealability is compared independent rubber sheet gasket and stationary seal ring with shock-absorbing capacity; (3) structural stability, reliability is better.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is mounting point of the present utility model schematic diagram.
In figure, body 1, buffering projection 2, sealed department 3, seal ring 4, clamping ring 5, draw-in groove 6, centralized positioning face 7, positioning convex 8, conical surface 9, bonnet 10, cylinder body 11, piston 12.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
In embodiment as shown in Figure 1, a kind of cylinder back cover cushion seal structure, comprises circular body 1, and the body in the present embodiment is to adopt NBR rubber to make.The edge of body 1 is bent to form sealed department 3 towards the direction perpendicular to body 1 surface, and the edge of sealed department 3 is provided with the seal ring 4 that protrudes from sealed department 3 outer surfaces, and body 1 is provided with the buffering projection 2 with body 1 integrative-structure away from the surface of sealed department 3.Ringwise and coaxially arranged with body 1, the distance at buffering projection 2 relative body 1 centers is less than the distance at sealed department 3 relative body 1 centers to buffering projection 2.Body 1 is provided with positioning convex 8 towards the centre of surface of sealed department 3, and it is conical that positioning convex 8 is.In body 1, a side at mind-set sealed department 3 places is protruded and is formed centralized positioning face 7, and the surrounding of centralized positioning face 7 is provided with conical surface 9.The internal surface of sealed department 3 is provided with the clamping ring 5 corresponding with seal ring 4 positions, between clamping ring 5, sealed department 3 and body 1, forms draw-in groove 6.
As shown in Figure 2, this cushion seal structure is installed on the bonnet 10 of cylinder, completes fixingly by clamping ring 5 and draw-in groove 6 and bonnet 10, and installation process is comparatively convenient and swift.After installation, its cross section is " bow " font.Wherein, the positioning convex 8 on centralized positioning face 7 can prevent that buffering projection 2 is offset, the stability while improving buffering.When piston 12 impacts bonnet 10, buffering projection 2 active forces that are subject to will make sealed department 3 expand outwardly, and seal ring 4 is further pushed, and the sealing effect between cylinder body 11 is improved.Through overtesting, also prove that this structure is more outstanding and reliable at Performance Ratio independence rubber sheet gasket and the stationary seal ring of buffering and seal aspect.
