Description
Technical field
The present invention relates to a kind of Novel double-acting single-piston rod-type hydraulic cylinder.
Background technology
The structure of existing double acting single-piston rod-type hydraulic cylinder is to be provided with piston, piston in oil cylinder
Side be connected to piston rod；In oil cylinder, the side not having piston rod is the first oil pocket (big chamber),
The side of corresponding piston rod is the second oil pocket (loculus)；Being respectively arranged at two ends with of oil cylinder first is entered
Oil-out and the second oil inlet and outlet, the first oil inlet and outlet is oily for the first oil pocket (big chamber) turnover,
Second oil inlet and outlet is for the second oil pocket (loculus) turnover oil.Piston is divided into two chambeies oil cylinder,
The biggest chamber and loculus, during hydraulic cylinder works, first oil inlet and outlet at two ends, the second oil inlet and outlet
Alternately provide pressure oil or oil return, to realize the bidirectional-movement of piston.Owing to little intracavity is provided with work
Stopper rod, thus big chamber is different with the effective active area of loculus, so that the big chamber of oil cylinder and loculus
Dischargeable capacity unequal.When flow one timing, due to big chamber and the difference of loculus dischargeable capacity,
Pressure oil enters, by the first oil-in, the time pressure to be longer than that the first oil pocket (big chamber) does work
Oil enters, by the second oil-in, the time that the second oil pocket (loculus) does work, and i.e. piston is by loculus
It is more than piston by big chamber to movement velocity v1 of little cavity direction to movement velocity v2 of big cavity direction,
The thickest then speed difference of piston rod is the biggest, affects hydraulic cylinder work efficiency in plant equipment.
Summary of the invention
The goal of the invention of the present invention is to provide a kind of Novel double-acting single-piston rod-type hydraulic cylinder,
Effectively reduce piston movement velocity of two directions of motion in oil cylinder poor.
Realize the object of the invention technical scheme:
A kind of Novel double-acting single-piston rod-type hydraulic cylinder, is provided with piston, the outside of piston in oil cylinder
It is connected to piston rod；In oil cylinder, the inner side of corresponding piston is the first oil pocket, and the outside of corresponding piston is
Second oil pocket；Oil cylinder be respectively arranged at two ends with the first oil inlet and outlet and the second oil inlet and outlet, first enters
Oil-out is for the first oil pocket turnover oil, and the second oil inlet and outlet is for the second oil pocket turnover oil, and it is special
Levying and be: the end of oil cylinder, corresponding first oil pocket is additionally provided with auxiliary oil inlet and outlet, auxiliary turnover oil
Mouth is for the first oil pocket turnover oil.
Described auxiliary oil inlet and outlet can be provided with multiple.
The invention have the benefit that
The present invention is in the end of oil cylinder, and corresponding first oil pocket (big chamber) is additionally provided with auxiliary turnover oil
Mouthful, auxiliary oil inlet and outlet is for the first oil pocket (big chamber) turnover oil.Due to be additionally arranged assist into
Oil-out, thus add pressure oil or the stream of into and out first oil pocket of oil return (big chamber)
Amount, is effectively improved piston by big chamber to movement velocity v1 of little cavity direction, effectively reduces piston and exists
In oil cylinder, the movement velocity of two directions of motion is poor, until it is poor to eliminate movement velocity, thus effectively
Improve the mechanical efficiency of oil cylinder.Simultaneously as the increase of big chamber return flow, return oil pressure subtracts
Little, piston also can be improved to movement velocity v2 of big cavity direction by loculus simultaneously, oil cylinder
Mechanical efficiency can be increased exponentially, and whole efficiency and the performance of plant equipment all obtains simultaneously
It is substantially improved.
Accompanying drawing explanation
Accompanying drawing is the structural representation of the present invention.
Detailed description of the invention
As it can be seen, be provided with piston 1 in oil cylinder, the right side (outside) of piston 1 is connected to piston rod
2；In oil cylinder, the left side (inner side) of corresponding piston is the first oil pocket A, the right side of corresponding piston
(outside) is the second oil pocket B；Oil cylinder be respectively arranged at two ends with the first oil inlet and outlet A ' and second
Oil inlet and outlet B ', the first oil inlet and outlet A ' are for the first oil pocket A turnover oil, the second turnover oil
Mouth B ' is for the second oil pocket B turnover oil, and this is prior art.In prior art, piston is oil
Cylinder is divided into the first oil pocket A (the biggest chamber) and the second oil pocket B (i.e. loculus), during hydraulic cylinder works,
First oil inlet and outlet A ', the second oil inlet and outlet B ' alternately provide pressure oil or oil return, to realize
The bidirectional-movement of piston.Owing to little intracavity is provided with piston rod, thus big chamber and the effective of loculus make
Different, so that the dischargeable capacity of the big chamber of oil cylinder and loculus is unequal with area.When flow is certain
Time, due to big chamber and the difference of loculus dischargeable capacity, pressure oil passes through the first oil-in A ' entrance
The time pressure oil to be longer than that first oil pocket A (big chamber) does work passes through the second oil-in B ' entrance
The time that second oil pocket B (loculus) does work, i.e. piston by loculus to the movement velocity of big cavity direction
V2 is more than piston by big chamber to movement velocity v1 of little cavity direction, and the thickest then speed difference of piston rod is more
Greatly, hydraulic cylinder work efficiency in plant equipment is affected.
The present invention is in the end of oil cylinder, and corresponding first oil pocket A sets up auxiliary oil inlet and outlet
A ' 1, auxiliary oil inlet and outlet A ' 1 are for the first oil pocket A turnover oil.As required, auxiliary turnover
Hydraulic fluid port can be provided with multiple, and auxiliary oil inlet and outlet bore sets as required.Auxiliary owing to being additionally arranged
Help oil inlet and outlet, thus add pressure oil or into and out first oil pocket of oil return (big chamber)
Flow, be effectively improved piston by big chamber to movement velocity v1 of little cavity direction, effectively reduce work
Plug movement velocity of two directions of motion in oil cylinder is poor, until it is poor to eliminate movement velocity, thus
It is effectively improved the mechanical efficiency of oil cylinder.Simultaneously as the increase of big chamber return flow, oil return is carried on the back
Pressure reduces, and piston also can be improved to movement velocity v2 of big cavity direction by loculus simultaneously, oil
The mechanical efficiency of cylinder can be increased exponentially, and the whole efficiency of plant equipment and performance are all simultaneously
It is increased dramatically.
