Description
Technical field
The utility model relates to the oil cylinder technical field of synchronization motion, particularly relates to the device of the large load operation platform of a kind of integral type non-concentric piston rod oil cylinder movement.
Background technique
At present, in engineering, when using the large load weight of oil cylinder movement, the generally easy piston rod that oil cylinder is stretched out, be squeezed distortion, causes the leakage of oil of oil cylinder when mobile large load weight, cause oil cylinder to damage time serious, need repairing oil cylinder, or change oil cylinder, affects project progress.
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model provides the device of the large load operation platform of a kind of integral type non-concentric piston rod oil cylinder movement.
For achieving the above object, the technical solution of the utility model is:
The device of the large load operation platform of a kind of integral type non-concentric piston rod oil cylinder movement, have two identical the first oil cylinders and be fixedly connected with formation by housing with the second oil cylinder reverse parallel connection, described first oil cylinder inner piston rod is fixedly connected with the large load operation platform one end be positioned on guide rail by connecting rod; The second reverse oil cylinder inner piston rod is fixedly connected with the large load operation platform the other end be positioned on guide rail by connecting rod.
A device for the large load operation platform of integral type non-concentric piston rod oil cylinder movement, the first described oil cylinder, the second oil cylinder are the elongated oil cylinder of the external ouput force of tension state, and the slenderness ratio of its piston diameter and diameter of piston rod is more than or equal to 5; Piston rod is the High Yield Stress Steel that yield strength is greater than 1000MPa.
Owing to adopting technological scheme as above, the utility model has following beneficial effect:
The utility model can use worktable and the weight of the large load of long thin oil cylinder movement, by long thin oil cylinder pulling force back and forth, pull worktable and the weight of large load, avoid the piston rod stretching out oil cylinder, be squeezed distortion, and cause leakage of oil, the damage of oil cylinder, decrease the maintenance of oil cylinder, improve project progress.Its structure is simple, and reliability is high, low cost of manufacture.
First oil cylinder of dual action cylinder of the present utility model, the second oil cylinder more adapt to the occasion that elongated oil cylinder uses, emphasize in the external ouput force of tension state, the other end is stressed very little, guarantee there will not be depression bar to be out of shape, and the first oil cylinder of dual action cylinder, the piston diameter of the second oil cylinder and the slenderness ratio of diameter of piston rod are more than or equal to 5; Piston rod material is higher yield strength, and as 30CrMnSi, 40CrMoV, 60Si2MnA, 40CrNiMo, 55CrSi, 18Ni300 etc., yield strength, more than 1000MPa, like this under oil pressure higher state, more easily plays piston rod material yield strength characteristic.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Accompanying drawing l is the structural representation that the two rod oil cylinder of non-concentric connects shuttle table.
In figure: 1, the first oil cylinder, the 2, second oil cylinder, 3, large load operation platform, 4, connecting rod.
Embodiment
As shown in Figure 1, the device of the large load operation platform of a kind of integral type non-concentric piston rod oil cylinder movement, have two identical the first oil cylinders 1 and be fixedly connected with formation by housing with the second oil cylinder 2 reverse parallel connection, described first oil cylinder 1 inner piston rod is fixedly connected with large load operation platform 3 one end be positioned on guide rail by connecting rod 4; The second reverse oil cylinder 2 inner piston rod is fixedly connected with large load operation platform 3 the other end be positioned on guide rail by connecting rod 4.
During use, adopt the pulling force of the first oil cylinder 1 inner piston rod return of integral type non-concentric piston rod oil cylinder, moved to A direction by the large load operation platform 3 on connecting rod 4 sliding guides, when large load operation platform 3 moves in B direction round about, adopt the pulling force of the second oil cylinder 2 inner piston rod return, moved in B direction round about by the large load operation platform 3 on connecting rod 4 sliding guides; Specifically be implemented as follows:
1 works as large load operation platform 3 moves to A direction, oil inlet hole oil-feed in first oil cylinder 1 rod chamber, first oil cylinder 1 inner piston rod return, moved to A direction by the large load operation platform 3 on connecting rod 4 sliding guides, oil inlet hole oil-feed in second oil cylinder 2 rodless cavity, auxiliary second oil cylinder 2 inner piston rod stretches out;
2 work as large load operation platform 3 moves to B direction, oil inlet hole oil-feed in second oil cylinder 2 rod chamber, second oil cylinder 2 inner piston rod return, moved to B direction by the large load operation platform 3 on connecting rod 4 sliding guides, oil inlet hole oil-feed in first oil cylinder 1 rodless cavity, auxiliary first oil cylinder 1 inner piston rod stretches out;
Alternately pulling back of 3 above-mentioned first oil cylinder 1 inner piston rods and the second oil cylinder 2 inner piston rod, reaches large load operation platform 3 and moves back and forth, and avoids piston rod and to be squeezed the stress of distortion and the damage of oil cylinder.
First oil cylinder of the dual action cylinder of the device of above-mentioned integral type non-concentric piston rod oil cylinder movement large load operation platform, the second oil cylinder more adapt to the occasion that elongated oil cylinder uses, emphasize in the external ouput force of tension state, the other end is stressed very little, guarantee there will not be depression bar to be out of shape, and the first oil cylinder of dual action cylinder, the piston diameter of the second oil cylinder and the slenderness ratio of diameter of piston rod are more than or equal to 5; Piston rod material is higher yield strength, and as 30CrMnSi, 40CrMoV, 60Si2MnA, 40CrNiMo, 55CrSi, 18Ni300 etc., yield strength, more than 1000MPa, like this under oil pressure higher state, more easily plays piston rod material yield strength characteristic.
