Abstract
A kind of hydraulic shear oil cylinder, main body is made up of cylinder body, piston rod, described piston rod is telescopic is arranged on cylinder interior, described piston rod inner hollow, a piston is provided with bottom piston rod, inner chamber of cylinder block is divided into rod chamber and rodless cavity by described piston, described piston rod inner is provided with one group and stretches out oil inlet pipe and one group of retraction return tube, described oil inlet pipe and the oil inlet and outlet of return tube are all arranged on the piston rod, described oil inlet pipe leads to rodless cavity, and described return tube leads to rodless cavity.The beneficial effects of the utility model are: the utility model is novel in design, structure is simple, not only facilitate and use in the confined space, ensure that oil pipe to collide and produce damaged cracking, decreasing the volume of overall oil cylinder, thus also widened the using scope of oil cylinder, make simple, easy to use, market value is high, is convenient to utilization and extention.
Description
Technical field
The utility model relates to hydraulic jack and manufactures field, is specifically related to a kind of hydraulic shear oil cylinder.
Background technique
Along with the development of Chinese Industrialization process, the development also of large-scale assembling manufacturing, oil cylinder is as the executive component of power, all play an important role in all trades and professions, its feature is exactly: steadily, the advantages such as High power output, and oil cylinder kind general on market is single double-action; Hydraulic shear oil cylinder is mainly used on orcible entry hydraulic shear, because forcible entry tool is when the use of reality, the space of itself is less, collider can be caused to swipe to oil cylinder in use for a long time simultaneously, traditional its oil pipe of hydraulic shear oil cylinder is all outside exposed oil hydraulic cylinder, like this in daily work, is easy to the breakage causing oil pipe, cause the disorder of whole hydraulic oil system, cause oil cylinder to damage.
Model utility content
It is simple, easy to use that technical problem to be solved in the utility model is to provide a kind of structure, takes up room little, the hydraulic shear oil cylinder that Safety performance is strong.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of hydraulic shear oil cylinder, main body is by cylinder body, piston rod forms, it is characterized in that: described piston rod is telescopic is arranged on cylinder interior, described piston rod inner hollow, a piston is provided with bottom piston rod, inner chamber of cylinder block is divided into rod chamber and rodless cavity by described piston, described piston rod inner is provided with one group of oil inlet pipe and one group of return tube, and return tube directly utilizes piston rod inner hollow to be formed, described oil inlet pipe and the hydraulic fluid port of return tube are all arranged on the piston rod, described oil inlet pipe leads to rodless cavity, described return tube leads to rod chamber.
Described piston is provided with a seal ring, ensure that piston and inboard wall of cylinder block fit tightly, sealing is stronger.
The utility model is in use: hydraulic oil enters into rodless cavity by oil inlet pipe, and in rodless cavity, hydraulic oil can promote piston and piston rod is protruding, and the hydraulic oil in rod chamber can be back in hydraulic system due to the propelling of piston, thus completes propelling action; Hydraulic oil enters in rod chamber by return tube, and in rod chamber, hydraulic oil can promote piston and piston rod to being retracted into, and the hydraulic oil in rodless cavity can be got back in hydraulic system due to the propelling of piston, thus completes indentation action.
The beneficial effects of the utility model are: the utility model is novel in design, structure is simple, not only facilitate and use in the confined space, ensure that oil pipe to collide and produce damaged cracking, decreasing the volume of overall oil cylinder, thus also widened the using scope of oil cylinder, make simple, easy to use, market value is high, is convenient to utilization and extention.
Accompanying drawing explanation
Fig. 1 is the utility model piston rod retracted mode figure;
Fig. 2 is that the utility model piston rod stretches out phase diagram.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As Fig. 1, shown in Fig. 2, a kind of hydraulic shear oil cylinder, main body is by cylinder body 1, piston rod 2 forms, piston rod 2 is telescopic is arranged on cylinder body 1 inside, piston rod 2 inner hollow, a piston 3 is provided with bottom piston rod 2, inner chamber of cylinder block is divided into rod chamber 4 and rodless cavity 5 by piston 3, piston rod 2 inside is provided with one group and stretches out oil inlet pipe 6 and one group of retraction return tube 7, the filler opening 8 and the return opening 9 that stretch out oil inlet pipe 6 and retraction return tube 7 are all arranged on piston rod 2, stretch out oil inlet pipe 6 and lead to rodless cavity 5, retraction return tube 7 leads to rod chamber 4, hydraulic oil enters into rodless cavity 5 by filler opening 8 to oil inlet pipe 6, in rodless cavity 5, hydraulic oil can promote piston 4 and piston rod 2 outwards exports, hydraulic oil in rod chamber 4 can because of the propelling of piston 3, get back in hydraulic system by return tube 7 and return opening 9, thus complete extend action, hydraulic oil by return opening 9 to return tube 7, wherein piston rod inner cavity is as drainback passage, enter into rod chamber 4, in rod chamber 4, hydraulic oil can promote piston 4 and piston rod 2 to reclaiming, hydraulic oil in rodless cavity 5 can because of the propelling of piston 3, got back in hydraulic system by oil inlet pipe 6 and filler opening 8, thus complete retract action, piston 3 is provided with a seal ring 10, ensure that piston 3 and cylinder body 1 inwall fit tightly, ensure that oil-feed is unobstructed simultaneously.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
