In said program, the second sealing device and third sealing device are equipped between the ontology and piston rod.
The advantages of the utility model and advantageous effect are：The utility model provides a kind of easy to use, safe and reliable
Hydraulic-driven tensioner centering component.The utility model uses in the case of needing internal diameter to position and be clamped for workpiece, positioning accurate
Degree is high, and inner hole of workpiece size does not influence its use, and its use simple in structure very safe ready.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, other drawings may also be obtained based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the sectional view of the utility model.
In figure：1, ontology 2, end cap 3, piston rod 4, ringfeder
5, end face 6, fixed plate 7, screw 8, first sealing device
9, the second sealing device 10, third sealing device 11, oil inlet 12, oil outlet
Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below
Example is only used for clearly illustrating the technical solution of the utility model, and the protection model of the utility model cannot be limited with this
It encloses.
As shown in Figure 1 and Figure 2, the utility model is a kind of hydraulic-driven tensioner centering component, including ontology 1, end cap 2, work
Stopper rod 3, ringfeder 4, end face 5 and fixed plate 6, ontology 1 include supporting table and protrusion, and 1 lower end of ontology is equipped with end cap 2, is set in ontology 1
There are piston rod 3, ontology 1 to be equipped with ringfeder 4, ringfeder 4 is sheathed on the outside of protrusion, and ringfeder 4 is equipped with end face 5, and end face 5, which penetrates, rises
In set 4, fixed plate 6 is additionally provided in supporting table, fixed plate 6 is used for fixing ontology 1, and end face 5 is equipped with stomidium, and it is oblique that protrusion is outer
Face is respectively equipped with oil inlet 11 and oil outlet 12 in supporting table.
Blind rivet is equipped in stomidium.Fixed plate 6 is fixed with screw 7.First sealing device 8 is equipped between end cap 2 and ontology 1.
The second sealing device 9 and third sealing device 10 are equipped between ontology 1 and piston rod 3.
Workpiece to be machined internal diameter is inserted into ringfeder 4, and for ringfeder 4 because of natural resiliency effect reduced profile, size is minimum at this time.It opens
Dynamic oil pressure, 11 oil inlet of oil inlet, piston rod 3 move down, and end face 5 pushes ringfeder 4 to move down, and ringfeder 4 is slow on central shaft inclined-plane
Slow sliding, 4 size of ringfeder gradually increase, and drive workpiece firmly close to positioning surface (i.e. raised inclined-plane) and set up a clamp
Clamp force, at this time 4 outer diameter of ringfeder be tightly adjacent to inner hole of workpiece, complete centering and clamp.After oil pressure is stablized, the executable processing of workpiece.It is complete
Finish, reversely lead to oil pressure, clamping piston bar 3 moves up, and ringfeder 4 is gradually reduced under natural resiliency effect, and along central shaft inclined-plane to
Upper movement, at this moment 4 outer diameter of ringfeder become smaller, workpiece facilitates extraction.
The utility model uses in the case of needing internal diameter to position and be clamped for workpiece, and positioning accuracy is high, inner hole of workpiece
Size does not influence its use, and its use simple in structure very safe ready.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
