Performance proposes new requirement, the efficient of such as equipment, energy-conservation, long lifespan, Environmental Safety, cost-effective, low noise, high efficiency
Energy-conservation, the waste gas discharge, smokeless and non-stimulated smell etc. of cleaning.With the raising of social productive forces, agriculture enterprise makes to equipment
New requirement is proposed with row performance.The security of equipment operation, stationarity, comfortableness turn into the later development trend of industry.
To adapt to the demand of agriculture enterprise, the oil cylinder has the advantages of locating distance of Multi-stage cylinder is small, and stroke is long, and applying working condition is severe, work frequency
Numerous, the cleannes of technical requirements and oil cylinder to each parts of oil cylinder require higher, therefore, we release a kind of integrated oil cylinders.
Utility model content
The purpose of this utility model is to provide a kind of integrated oil cylinders, to solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides following technical scheme：A kind of integrated oil cylinders, including the first cylinder body and
Second cylinder body, the rear surface of first cylinder body are provided with the first fuel feed hole, and the upper end face of second cylinder body is provided with second
Fuel feed hole, first cylinder body and the second cylinder body are structure as a whole, between first cylinder body and the second cylinder body by dividing plate every
To open, the inner chamber of first cylinder body is provided with the first cylinder barrel, and the inside of first cylinder barrel, which is slipped, First piston bar, and described first
The upper end of piston rod is provided with the first cylinder cap with the first cylinder barrel contact position, and the inner chamber of second cylinder body is provided with the second cylinder barrel, institute
State the second cylinder barrel inside it is sliding have a second piston bar, the lower end of the second piston bar and the second cylinder barrel contact position are provided with the
Two cylinder caps.
Preferably, the Tempering and Quenching hardness of first cylinder barrel, the second cylinder barrel, First piston bar and second piston bar：
HB240~280.
Preferably, the outside dimension precision of First piston bar and second piston bar the sealing mating surface must not be less than f8,
The external diameter surface roughness of First piston bar and second piston bar the sealing mating surface is Ra0.2.
Preferably, the dimensional accuracy of the endoporus sealing mating surface of first cylinder barrel and the second cylinder barrel must not be less than H7, institute
The surface roughness for stating the endoporus sealing mating surface of the first cylinder barrel and the second cylinder barrel is Ra0.2.
Compared with prior art, the beneficial effects of the utility model are：The utility model compares common oil cylinder, mounting distance
Shorter, compared to Multi-stage cylinder, fast ratio is smaller, the drawbacks of avoiding quick return, the column cleaning after pass the test, with 120 mesh/English
The filter filtering of very little precision, the online article drying of gained are weighed, and its weight must not exceed standard requirement, high-quality using import
Seal ensures sealing property, and oil cylinder operation is safer, and steadily, end impact is smaller, and noise is smaller, using refractory seals
Part, it is adapted to use under higher temperature.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
In figure：1 first cylinder body, 2 second cylinder bodies, 3 first cylinder barrels, 4 second cylinder barrels, 5 first fuel feed holes, 6 second fuel feed holes,
7 First piston bars, 8 second piston bars, 9 dividing plates, 10 second cylinder caps, 11 first cylinder caps.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, the utility model provides a kind of technical scheme：A kind of integrated oil cylinders, including the first cylinder body 1 and second
Cylinder body 2, the rear surface of first cylinder body 1 are provided with the first fuel feed hole 5, and the upper end face of second cylinder body 2 is provided with second
Fuel feed hole 6, the cylinder body 2 of the first cylinder body 1 and second are structure as a whole, between the cylinder body 2 of the first cylinder body 1 and second by every
Plate 9 separates, and the inner chamber of first cylinder body 1 is provided with the first cylinder barrel 3, and the inside of first cylinder barrel 3 is sliding First piston bar
7, upper end and the contact position of the first cylinder barrel 3 of the First piston bar 7 are provided with the first cylinder cap 11, the inner chamber of second cylinder body 2
