Abstract
A kind of structure of pressurized cylinder piston, it be by：Big piston, bolt, stationary gland, connection axle journal, valve piston are formed, stationary gland is the structure of circular ring shape, make the ladder hole being made of small endoporus and big endoporus in the center of stationary gland, stationary gland is bolted on the centre of big piston side, connection axle journal is agreed with the ladder hole being made of small endoporus and big endoporus by the dome step of its one end, valve piston, a kind of pressurized cylinder are fixed with the other end of connection axle journal：The pressurized cylinder with above-mentioned piston whole feature, the present invention will not there is a phenomenon where interfering between piston and cylinder body, and thus trigger it is easy occur abrasion, scuffing of cylinder bore accident generation, cause internal leakage, work unreliable；The defects of also reducing the service life of equipment at the same time.
Description
Technical field
The present invention relates to the structure and pressurized cylinder of pressurized cylinder piston, belong to pressurized cylinder technical field.
Background technology
It is well known that the piston of pressurized cylinder is made of two pistons of size, two pistons of size are separately positioned on two
In a two cylinder bodies of corresponding size in same axial direction, in existing technology, two pistons of size of pressurized cylinder are all
It is rigidly fixed on same axis, this structure has the advantages that simple in structure, craftsmanship is preferable, still, by
In manufacture installation error inevitably exist, two pistons of size necessarily can not possibly completely on an axis,
Meanwhile matched size cylinder body exists due to manufacturing installation error, two cylinder bodies of size can not possibly necessarily exist completely
On one axis, the presence of these errors is close by the corresponding size cylinder body binding site for causing big valve piston matched
Degree is different, and easy appearance is worn, the generation of the accident of scuffing of cylinder bore, causes internal leakage, work unreliable；Also reduce at the same time
The service life of equipment.
The content of the invention
It is an object of the invention to：For the drawbacks described above present in the prior art, the present invention provides one kind can be effective
Overcome the structure and pressurized cylinder of the new pressurized cylinder piston of drawbacks described above.
Technical solution is used by the present invention realizes above-mentioned purpose：
A kind of structure of the pressurized cylinder piston, it be by：Big piston 1, bolt 2, stationary gland 3, connection axle journal 4, small work
Plug 5 is formed, and the stationary gland 3 is the structure of circular ring shape, is made at the center of stationary gland 3 by small endoporus 7 and imperial palace
The ladder hole that hole 8 is formed, stationary gland 3 are fixed on the centre of big 1 side of piston by bolt 2, and small endoporus 7
Opening direction is outside, and connection axle journal 4 is agreed with the rank being made of small endoporus 7 and big endoporus 8 by the dome step 6 of its one end
Terraced through hole, further：The diameter of small endoporus 7 is more than the diameter of place position connection axle journal 7 and is less than big endoporus 8, and greatly
8 diameter of endoporus is more than the diameter of dome step 6, is fixed with valve piston 5 in the other end of connection axle journal 7, further：It is described
Big piston 1 and valve piston 5 it is cylindrical on be respectively arranged with the first seal groove 10 and the second seal groove 9.
A kind of pressurized cylinder：It is the pressurized cylinder with above-mentioned piston whole feature.
Beneficial effect：In the present invention, since the axial line between big piston 1 and valve piston 5 can be by connecting on axle journal 4
Dome step 6 and the ladder hole that is made of small endoporus 7 and big endoporus 8 between gap adjustment, compensate due to manufacture with
The error of installation, so, will not there is a phenomenon where interfering between piston and cylinder body, and thus trigger it is easy occur abrasion,
The generation of the accident of scuffing of cylinder bore, causes internal leakage, work unreliable；The defects of also reducing the service life of equipment at the same time.
Brief description of the drawings
Fig. 1 is the structure principle chart of the present invention；
Shown in figure：1 be big piston, 2 be bolt, 3 be stationary gland, 4 be connection axle journal, 5 be valve piston, 6 be dome step,
7 it is small endoporus, 8 be big endoporus, 9 be the second seal groove, 10 is the first seal groove.
Embodiment
With reference to Fig. 1, embodiment of the invention is：
A kind of structure of pressurized cylinder piston, it be by：5 big piston 1, bolt 2, stationary gland 3, connection axle journal 4, valve piston groups
Into the stationary gland 3 is the structure of circular ring shape, is made at the center of stationary gland 3 by small endoporus 7 and big 8 groups of endoporus
Into ladder hole, stationary gland 3 is fixed on the centre of big 1 side of piston, and the opening side of small endoporus 7 by bolt 2
To outside, connection axle journal 4 is agreed with by the dome step 6 of its one end to be led in the ladder being made of small endoporus 7 with big endoporus 8
Hole, further：The diameter of small endoporus 7 is more than the diameter of place position connection axle journal 7 and is less than big endoporus 8, and big endoporus 8
Diameter is more than the diameter of dome step 6, is fixed with valve piston 5 in the other end of connection axle journal 7, further：Described is big
Piston 1 and valve piston 5 it is cylindrical on be respectively arranged with the first seal groove 10 and the second seal groove 9.
A kind of pressurized cylinder：It is the pressurized cylinder with above-mentioned piston whole feature.
Finally it should be noted that：The above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof；To the greatest extent
The present invention is described in detail with reference to preferred embodiments for pipe, those of ordinary skills in the art should understand that：Still
It can modify to the embodiment of the present invention or equivalent substitution is carried out to some technical characteristics；Without departing from this hair
The spirit of bright technical solution, it should all cover in the claimed technical solution scope of the present invention.
