Abstract
The utility model is related to a kind of large_sized hydraulic cylinder universal coupling, with sphere base, sphere bar and sphere end cap；The sphere lower half of the sphere bar bottom is arranged in sphere base, and the sphere first half is pushed down by sphere end cap, and the upper end of sphere bar is threadedly coupled with end terminal pad, and is fixed between the top of sphere bar and end terminal pad by straight pin；It is fixedly connected between the sphere end cap and sphere base by the 3rd screw and spring washer；Sphere-contact gap is adjusted by pad between the sphere base and sphere end cap, sphere base is fixedly mounted on spheric seating by the first screw；The end terminal pad is fixedly connected with pinboard by the second screw, and by positioning finger setting concentricity between end terminal pad and pinboard.The utility model eliminates gap by adjusting multi-disc adjust pad, and intensity is high, and accuracy is good, while can increase sphere lifting surface area.
Description
Technical field
The utility model is related to mechanics machine manufacturing technology field, more particularly to a kind of large_sized hydraulic cylinder universal coupling.
Background technology
Piston hydraulic cylinder has higher service behaviour, so, obtained in the hydraulic control system for requiring higher extensively
Using.But in larger-diameter piston cylinder, due to the reason such as processing, installing, using, hydraulic cylinder piston is produced beat, liquid
When the piston rod center of cylinder pressure and misaligned outer load effect center, piston rod can be by very big uneven loading action, in radially meeting
Larger moment of flexure is produced to produce larger bending stress, will if exceeding tolerance band beyond allowable stress or deformation
Cause piston rod unstability or even fracture, have a negative impact to cylinder device, and unbalance loading also easily makes hydraulic cylinder produce part
Abrasion, causes leakage, can not be worked when serious, reduce its working life.
The content of the invention
The purpose of this utility model be the defect for overcoming prior art to exist there is provided a kind of simple in construction, good positioning effect,
Good concentricity, the large_sized hydraulic cylinder universal coupling of sphere lifting surface area can be increased.
Realizing the technical scheme of the utility model purpose is：A kind of large_sized hydraulic cylinder universal coupling, with sphere base, ball
Face bar and sphere end cap；The sphere lower half of the sphere bar bottom is arranged in sphere base, and the sphere first half passes through sphere
End cap is pushed down, and the upper end of sphere bar is threadedly coupled with end terminal pad, and is passed through between the top of sphere bar and end terminal pad
Straight pin is fixed；It is fixedly connected between the sphere end cap and sphere base by the 3rd screw and spring washer；The sphere
Sphere-contact gap is adjusted by pad between base and sphere end cap, sphere base is fixedly mounted on sphere by the first screw
On seat；The end terminal pad is fixedly connected with pinboard by the second screw, and is passed through between end terminal pad and pinboard
Position finger setting concentricity.
Pad described in above-mentioned technical proposal is combined by the ultra-thin pad of multi-disc and formed.
After adopting the above technical scheme, the utility model has following positive effect：
(1) the utility model eliminates gap by adjusting multi-disc adjust pad, and intensity is high, and accuracy is good, while can
To increase sphere lifting surface area.
(2) concentricity is positioned by alignment pin 8 between end terminal pad 5 of the present utility model and pinboard 6, it is ensured that whole
The concentricity that ball is twisted.
Brief description of the drawings
In order that content of the present utility model is easier to be clearly understood, below according to specific embodiment and with reference to attached
Figure, is described in further detail to the utility model, wherein
Fig. 1 is structural representation of the present utility model；
Embodiment
(embodiment 1)
See Fig. 1, the utility model has sphere base 1, sphere bar 4 and sphere end cap 3；Under the sphere of the bottom of sphere bar 4
Half portion is arranged in sphere base 1, and the sphere first half is pushed down by sphere end cap 3, it is ensured that sphere can freely activity, sphere bar 4
Upper end be threadedly coupled with end terminal pad 5, prevent from loosening, and pass through cylinder between the top of sphere bar 4 and end terminal pad 5
Pin 13 is fixed；It is fixedly connected between sphere end cap 3 and sphere base 1 by the 3rd screw 9 and spring washer 12；Sphere base 1
Sphere-contact gap is adjusted by pad 2 between sphere end cap 3, Spherical Clearance can be accurately adjusted, sphere base 1 passes through the
One screw 11 is fixedly mounted on spheric seating 7；Pad 2 is combined by the ultra-thin pad of multi-disc and formed.End terminal pad 5 and pinboard 6
It is fixedly connected by the second screw 10, and concentricity is positioned by alignment pin 8 between end terminal pad 5 and pinboard 6.
Particular embodiments described above, has carried out entering one to the purpose of this utility model, technical scheme and beneficial effect
Step is described in detail, be should be understood that and be the foregoing is only specific embodiment of the utility model, is not limited to this
Utility model, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvements done etc. all should be wrapped
It is contained within protection domain of the present utility model.
