Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As it is shown in figure 1, one multiaction power multi-speed oil cylinder of the present invention, including piston rod 1, cylinder barrel 2 and the cylinder with mandrel
Lid 3；Piston rod 1 is inside cylinder barrel 2, and forms the second acting chamber 8, piston rod 1 inner hollow with cylinder barrel, and is stretching out cylinder barrel 2
One end have the 3rd hydraulic fluid port 6；The first acting chamber 7 is collectively formed with cylinder cap 3 and the piston rod 1 and cylinder barrel 2 of mandrel, and with
The mandrel of the cylinder cap 3 of mandrel constitutes the 3rd acting chamber 9 with the hollow space of piston rod 1；Described 3rd hydraulic fluid port 6 and the 3rd acting chamber
9 connections；Oil cylinder 2 top and the bottom have the second hydraulic fluid port 5 and the first hydraulic fluid port 4, and the first hydraulic fluid port 4 connects with the first acting chamber 7, the second hydraulic fluid port
5 connect with the second acting chamber 8.Wherein, separate between first acting chamber the 7, second acting chamber the 8, the 3rd acting chamber 9, have close
Packing is disconnected.
Here piston rod 1 active area of the first acting chamber 7 correspondence, piston rod 1 acting surface of the second acting chamber 8 correspondence
Long-pending, piston rod 1 active area of the 3rd acting chamber 9 correspondence can be designed on demand.As in figure 2 it is shown, the present invention provides one
Implementing row, piston rod 1 active area of the first acting chamber 7 correspondence is more than piston rod 1 active area of the 3rd acting chamber 9 correspondence,
And assume that the oil liquid pressure that each chamber acts on is equal, the constant flow of hydraulic power supply 11.Its operation principle is as follows: first, when
When needing piston rod 1 low speed to stretch out or there is the active force of maximum, supplied to the first acting chamber 7 by the first hydraulic fluid port 4, control valve 10
Pressure oil, the 3rd hydraulic fluid port 6 is to the 3rd acting chamber 9 for pressure oil, and the fluid in the second acting chamber 8 is through the second hydraulic fluid port 5, control valve 10
Enter fuel tank 12.Now piston rod 1 has minimum speed, maximum active force.Secondly, when needs piston rod 1 middling speed is stretched out
Or when there is medium active force, by the first hydraulic fluid port 4, control valve 10 to the first acting chamber 7 for pressure oil, the 3rd acting chamber 9
Interior fluid fills into no pressure oil through the 3rd hydraulic fluid port 6, control valve 10, and the fluid in the second acting chamber 8 is through the second hydraulic fluid port 5, control
Valve 10 enters fuel tank 12.Now piston rod 1 has medium speed, medium active force.Again, when needs piston rod 1 high speed
When stretching out or there is minimum active force, by the 3rd hydraulic fluid port 6, control valve 10 to the 3rd acting chamber 9 for pressure oil, the first effect
Fluid in chamber 7 fills into no pressure oil through the first hydraulic fluid port 4, control valve 10, and the fluid in the second acting chamber 8 is through the second hydraulic fluid port 5, control
Valve 10 processed enters fuel tank 12.Now piston rod 1 has the highest speed, minimum active force.Finally, contract when needs piston rod 1
Hui Shi, by the second hydraulic fluid port 5, control valve 10 to the second acting chamber 8 for pressure oil, the fluid in the first acting chamber 7 is through the first oil
Mouth 4, control valve 10 enter fuel tank 12, and the fluid in the second acting chamber 8 enters fuel tank 12 through the second hydraulic fluid port 5, control valve 10.
Thus, present invention achieves oil cylinder and stretch out the third gear change of speed and power output, and the length direction of oil cylinder is installed
Size is not changed in.The above-mentioned embodiment that is given is first hydraulic fluid port the 4, second hydraulic fluid port 5 and the 3rd hydraulic fluid port 6 is connected by control valve 10
Hydraulic power supply 11 and fuel tank 12.Also can give each acting chamber logical oil respectively with different hydraulic power supplies, each acting chamber hydraulic pressure
Power also can be different, it is achieved different speed and the combination of power.
On the basis of said structure, the present invention can be integrated with the cylinder cap 3 of mandrel, its mandrel and cylinder cap, it is also possible to
It it is combination type.
Certainly, above-described embodiment is only the preferred version of the present invention, is specifically not limited thereto, on this basis can basis
It is actually needed to make having and adjusts targetedly, thus obtain different embodiments.Owing to mode in the cards is more, this
In illustrate the most one by one.
