The utility model discloses gas sets up a plurality of gas passageway that rises in the surface of axostylus axostyle department along its axial, set up the ejector pin in rising by the passageway to set up the sealing washer on the ejector pin, guarantee that gas leakage can not appear in air expansion shaft in the course of the work, owing to adopt a plurality of gas rise passageway and apical axis, guarantee the the stress homogeneity, just so the great improvement air expansion shaft's of ability life.
Description
Technical field
The utility model is related to a kind of gas expansion shaft, more particularly, to the gas expansion shaft expanded outwardly using air pressure.
Background technology
Gas expansion shaft is a kind of special winding, unreeling shaft, can be expanded by high-pressure aerated rear face portion point, table after deflation
The axle that face part is retracted rapidly.Air-expanding shaft is extremely easy to use, quick, only needs user to provide source of the gas for oneself, and air-pressure controlling is in 2-
In the range of 6kg, when need to lock reel core, as long as air gun just can be completed against the valve inflation on air-expanding shaft, reel core need to be loosened
During discharging, the slip gaseous core pressed with hand on valve is deflated.Traditional gas expansion shaft is by being arranged at axostylus axostyle inner hollow
Air bag is realized expanding outwardly different convex keys, but this kind of gas expansion shaft is unstable, and easily goes wrong；Work as air bag
Whole gas expansion shaft can be caused when generation gas leakage can not be used, and cause fault in production.
Utility model content
In order to solve the above-mentioned technical problem, the utility model purpose is：A kind of gas expansion shaft is provided, is risen the purpose is to reduce gas
The fault rate of axle, it is ensured that the effective of production is carried out.
The technical scheme that the utility model is used is：A kind of gas expansion shaft, including hollow axostylus axostyle, spindle nose, nest plate, apical axis
And top flat；Described spindle nose is fixedly mounted on hollow axostylus axostyle, wherein a spindle nose is provided with air admission hole；Described nest plate passes through
Screw is fixedly mounted on hollow axostylus axostyle；Described apical axis is arranged on hollow axostylus axostyle；Described top flat is solid by screw
Dingan County is on apical axis；Described apical axis is made up of spring, push rod and sealing ring；Seal groove is provided with described push rod, is pushed up
Four cylindrical holes are provided with bar step；Described sealing ring is arranged on seal groove；Described spring is arranged on cylindrical hole.
Further, described hollow axostylus axostyle is provided with cylinder shape groove.
Further, described spindle nose one end is provided with seal groove.
Further, described apical axis is in " convex " font.
Further, described top flat is made up of aluminium alloy；Described top flat can be smooth cambered surface, or
Toothed cambered surface.
The utility model has advantages below：The utility model sets multiple gas axially along in the outer surface of axostylus axostyle
Rise passage, and push rod is set in gas rises by passage, and sealing ring is set on push rod, it is ensured that gas expansion shaft will not go out in the course of the work
Existing gas leakage；Due to rising passage and apical axis using multiple gas, it is ensured that overall uniform force, gas expansion shaft can be thus greatly improved
Service life.
Brief description of the drawings
Fig. 1 is the utility model schematic cross-section.
Fig. 2 is the utility model schematic three dimensional views.
Label declaration：Top flat 1, nest plate 2, hollow axostylus axostyle 3, apical axis 4, sealing ring 5, spring 6, spindle nose 7, push rod 8.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing to this reality
It is further elaborated with new.It should be appreciated that specific embodiment described herein is only used to explain this practicality
It is new, it is not used to limit the utility model.
Shown in referring to the drawings：The technical scheme that the utility model is used is：A kind of gas expansion shaft, including hollow axostylus axostyle 3,
Spindle nose 7, nest plate 2, apical axis 4 and top flat 1；Described spindle nose 7 is fixedly mounted on hollow axostylus axostyle 3, wherein a spindle nose 7 is provided with
Air admission hole；Described nest plate 2 is fixedly mounted on hollow axostylus axostyle 3 by screw；Described apical axis 4 is arranged on hollow axostylus axostyle
On 3；Described top flat 1 is fixedly mounted on apical axis 4 by screw；Described apical axis 4 is by 5 groups of spring 6, push rod 8 and sealing ring
Into；Seal groove is provided with described push rod 8, four cylindrical holes are provided with the step of push rod 8；Described sealing ring 5 is arranged on close
On seal groove；Described spring 6 is arranged on cylindrical hole.
Further, described hollow axostylus axostyle 3 is provided with cylinder shape groove.
Further, described one end of spindle nose 7 is provided with seal groove.
Further, described apical axis 4 is in " convex " font.
Further, described top flat 1 is made up of aluminium alloy；Described top flat can be smooth cambered surface, it is also possible to
It is toothed cambered surface.
After product to be processed puts into gas expansion shaft, at this moment gas constantly squeezes into hollow from spindle nose 7 to start gas switch
Axostylus axostyle 3, causes that the hollow cavity pressure of axostylus axostyle 7 constantly increases due to hollow cavity closing, and top is just promoted when reaching 3 kilograms
Axle 4 is displaced outwardly, and then axle spreading is clamped processed product.The now hollow chamber of axostylus axostyle 7 of gas switch is closed after processing
Interior pressure is quickly reduced, and apical axis 4 acts on reinstatement negative pressure and spring 6, at this moment goes lower product to complete process.
Above-described embodiment only to illustrate technology design of the present utility model and feature, technique is familiar with its object is to allow
Personage will appreciate that content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.
All equivalent change or modifications made according to the utility model Spirit Essence, should all cover protection domain of the present utility model it
It is interior.
