Abstract
The invention relates to the technical field of oil cylinders with synchronization action, and discloses a device of an integrated non-concentric piston rod oil cylinder for moving a heavy-load working table. The integrated non-concentric piston rod oil cylinder for moving the heavy-load working table is formed by a first oil cylinder 1 and a second oil cylinder 2 which are the same and are fixedly connected in parallel reversely through a shell, wherein a piston rod in the first oil cylinder 1 is fixedly connected with one end of the heavy-load working table 3 located on a guide rail through a connecting rod 4; a piston rod in the reversed second oil cylinder 2 is fixedly connected with the other end of the heavy-load working table 3 located on the guide rail through the connecting rod 4. According to the device, the heavy-load working table and weights are pulled through back-and-forth pulling force of a long and thin oil cylinder of the device of the integrated non-concentric piston rod oil cylinder for moving the heavy-load working table, so that the phenomena of oil leakage and damage of the oil cylinder caused by the reason that the piston rod stretched out of the oil cylinder is extruded and deformed are avoided, the maintenance of the oil cylinder is reduced, the yield strength characteristic of materials of the piston rod under the state of higher oil pressure is realized, and the works programme is improved. The device is simple in structure, high in reliability and low in manufacturing cost.
Description
Technical field
The present invention relates to the oil cylinder technical field of synchronization motion, relate in particular to the device of the large load operation platform of the non-concentric piston rod oil cylinder movement of a kind of integral type.
Background technique
At present, in engineering, when using the large load weight of oil cylinder movement, the general easy piston rod that oil cylinder is stretched out, the distortion that is squeezed, causes the leakage of oil of oil cylinder in mobile large load weight, causes oil cylinder to damage when serious, the oil cylinder that needs repairing, or change oil cylinder, affect project progress.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides the device of the large load operation platform of the non-concentric piston rod oil cylinder movement of a kind of integral type.
For achieving the above object, technological scheme of the present invention is:
The device of the large load operation platform of the non-concentric piston rod oil cylinder movement of a kind of integral type, have two the first identical oil cylinders and be fixedly connected with formation by housing with the second oil cylinder reverse parallel connection, described the first oil cylinder inner piston rod is fixedly connected with the large load operation platform one end being 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 being positioned on guide rail by connecting rod.
A device for the large load operation platform of the non-concentric piston rod oil cylinder movement of integral type, the first described oil cylinder, the elongated oil cylinder that the second oil cylinder is the external ouput force of tension state, 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 present invention has following beneficial effect:
The present invention 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 stretching out the piston rod of oil cylinder, distortion is squeezed, and cause leakage of oil, the damage of oil cylinder, and reduce the maintenance of oil cylinder, improve project progress.It is simple in structure, and reliability is high, low cost of manufacture.
The first oil cylinder of dual action cylinder of the present invention, 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 distortion, and the first oil cylinder, the piston diameter of the second oil cylinder and the slenderness ratio of diameter of piston rod of dual action cylinder 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 exceedes 1000MPa, under oil pressure higher state, more easily brings into play piston rod material yield strength characteristics like this.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described.
The with one heart two rod oil cylinders of accompanying drawing l right and wrong connect the structural representation of shuttle table.
In figure: 1, the first oil cylinder, 2, the 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 the non-concentric piston rod oil cylinder movement of a kind of integral type, have two the first identical oil cylinders 1 and be fixedly connected with formation by housing with the second oil cylinder 2 reverse parallel connections, described the first oil cylinder 1 inner piston rod is fixedly connected with large load operation platform 3 one end that are positioned on guide rail by connecting rod 4; The second reverse oil cylinder 2 inner piston rods are fixedly connected with large load operation platform 3 the other ends that are positioned on guide rail by connecting rod 4.
When use, adopt the pulling force of the first oil cylinder 1 inner piston rod return of the non-concentric piston rod oil cylinder of integral type, move to A direction by the large load operation platform 3 on connecting rod 4 sliding guides, when large load operation platform 3 round about B direction move, adopt the pulling force of the second oil cylinder 2 inner piston rod returns, by the large load operation platform 3 on connecting rod 4 sliding guides round about B direction move; Specifically be implemented as follows:
1 works as large load operation platform 3 moves to A direction, oil inlet hole oil-feed in the first oil cylinder 1 rod chamber, the first oil cylinder 1 inner piston rod return, move to A direction by the large load operation platform 3 on connecting rod 4 sliding guides, oil inlet hole oil-feed in the second oil cylinder 2 rodless cavities, auxiliary the second oil cylinder 2 inner piston rods stretch out;
2 work as large load operation platform 3 moves to B direction, oil inlet hole oil-feed in the second oil cylinder 2 rod chambers, the second oil cylinder 2 inner piston rod returns, move to B direction by the large load operation platform 3 on connecting rod 4 sliding guides, oil inlet hole oil-feed in the first oil cylinder 1 rodless cavity, auxiliary the first oil cylinder 1 inner piston rod stretches out;
Alternately pulling back of 3 above-mentioned the first oil cylinder 1 inner piston rods and the second oil cylinder 2 inner piston rods, reaches large load operation platform 3 and moves back and forth, avoided piston rod be squeezed distortion stress and the damage of oil cylinder.
The first oil cylinder, second oil cylinder of the dual action cylinder of the device of the large load operation platform of the non-concentric piston rod oil cylinder movement of above-mentioned integral type more adapts 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 distortion, and the first oil cylinder, the piston diameter of the second oil cylinder and the slenderness ratio of diameter of piston rod of dual action cylinder 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 exceedes 1000MPa, under oil pressure higher state, more easily brings into play piston rod material yield strength characteristics like this.
