Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vibration test equipment, and particularly relates to a horizontal decoupling device for a hydraulic vibration test system. Background Art
[0002] In a triaxial hydraulic vibration test device, a decoupling device is required to connect a vibration working table and an exciter to eliminate the mutual influence during the operation of exciters in different directions, so that one exciter only controls the vibration output in one direction.
[0003] During the actual use process, even if the product is only subjected to the vibration force in a single direction, displacement will also occur in other directions. To simulate the real use environment of the test product, during the vibration test, it is necessary to completely release the restriction of the non-operating exciter on the vibration working table, and the exciter needs to be removed, which takes a long time and affects the efficiency and accuracy of the test.
[0004] Therefore, aiming at the deficiencies of the existing technology, it is necessary to design a horizontal decoupling device for a hydraulic vibration test system to solve the above problems.
[0005] It should be noted that the above introduction of the technical background is only for the convenience of clearly and completely explaining the technical solution of the utility model and facilitating the understanding of those skilled in the art. It cannot be considered that the above content is well-known to those skilled in the art just because these contents are described in the background art of the utility model. Summary of the Utility Model
[0006] To overcome the above deficiencies in the existing technology, the purpose of the utility model is to disclose a horizontal decoupling device for a hydraulic vibration test system, which solves the problem of difficult contact connection between the traditional decoupling device and the vibration test table.
[0007] The utility model discloses a horizontal decoupling device for a hydraulic vibration test system, which includes a vibration working table for placing a test product. A first slideway is arranged on the side of the vibration working table, and the first slideway is arranged along one vibration direction of the hydraulic vibration test system. A first slider is slidably connected to the first slideway. A second slideway is arranged on the side of the first slideway away from the vibration working table, and the second slideway is arranged along another vibration direction of the hydraulic vibration test system; a second slider is slidably connected to the second slideway. The first slider and the second slider are detachably connected together through a cross adapter block, and can be quickly separated when not in use, completely releasing the movement restriction of the exciter on the vibration working table at this horizontal decoupling device. The second slideway is arranged on a transition plate, and the transition plate is used to connect an external exciter. The vibration direction of the external exciter is different from the setting directions of the first slideway and the second slideway, so that the external exciter from the horizontal direction can use the horizontal decoupling device to eliminate the vibration influence from the other two directions.
[0008] Preferred technical solution: The cross transfer block is connected to the first slider and the second slider via a latch, making assembly and disassembly more convenient.
[0009] Preferred technical solution: the first slide is arranged along the side of the vibrating workbench to prevent the product on the vibrating workbench from colliding with the first slide; at least two first sliders are connected to the first slide, and the first sliders are all detachably connected to independent second sliders, and the second sliders are all connected to independent second slides. By arranging multiple second sliders on the first slide for connection, the balance of the connection is improved to avoid jamming during movement.
[0010] Preferred technical solution: Both ends of the first slide are provided with a first limit block for limiting the moving distance of the first slider; both ends of the second slide are provided with a second limit block for limiting the moving distance of the second slider to prevent the slider from detaching from the slide and causing damage to the device.
[0011] A preferred technical solution: the first slideway and the second slideway are both slide rail structures, and the first slider and the second slider are both provided with a slide groove structure that is slidably connected to the slide rail structure.
[0012] A preferred technical solution: the first slideway and the second slideway are both slide groove structures, and the first slider and the second slider are both provided with a slide rail structure that is slidably connected to the slide groove structure.
[0013] Due to the application of the above technical solution, the utility model has the following beneficial effects compared with the prior art:
[0014] The utility model is used for a horizontal decoupling device of a hydraulic vibration test system. Through a detachable double slideway design, it can complete the rapid connection and separation of the exciter and the vibration workbench, thereby improving the test efficiency. At the same time, it utilizes the slideway in conjunction with the slider to eliminate the influence of vibrations in other directions, so that the exciter does not need to swing to reduce external interference, thereby improving the control accuracy of the vibration output.

[0027] Embodiment 1:
[0028] As Figure 1 shown, the present utility model discloses a horizontal decoupling device for a hydraulic vibration test system, which includes a vibration working table 100 for placing test specimens, a first slideway 1, and a second slideway 2. The following will specifically describe the main components of the above present utility model:
[0029] As Figure 1 and Figure 2 shown, the first slideway 1 is a slide rail structure and is provided with first limit blocks 12 at both ends. The first slideway 1 is arranged along the side of the vibration working table 100 to avoid interference with the products on the vibration table; the arrangement direction of the first slideway 1 is the same as the vibration direction of the horizontal X-direction exciter. Three first sliders 11 are slidably connected to the first slideway 1, and the first sliders 11 are connected to the slide rails on the first slideway 1 through chutes;
[0030] As Figure 1 and Figure 2 shown, the second slideway 2 is a slide rail structure and is provided with second limit blocks 22 at both ends. The second slideway 2 is arranged on the side of the first slideway 1 away from the vibration working table 100. The arrangement direction of the second slideway 2 is the same as the vibration direction of the vertical Z-direction exciter; a second slider 21 is slidably connected to the second slideway 2, and the second slider 21 is connected to the slide rails on the second slideway 2 through chutes; the first slider 11 and the second slider 21 are detachably connected together through a cross transfer block 3 and a pin; the second slideway 2 is arranged on a transition plate 4, and the transition plate 4 is connected to the horizontal Y-direction exciter. The vibration direction of the horizontal Y-direction exciter is different from the arrangement directions of both the first slideway 1 and the second slideway 2. It should be noted that X, Y, and Z in the above horizontal X-direction exciter, horizontal Y-direction exciter, and vertical Z-direction exciter are only used to distinguish the exciters and do not specifically refer to a certain fixed direction.
[0031] Refer to Figure 1 and Figure 2As shown in the figure, when the utility model is in use, the vibration from the horizontal X-direction exciter will drive the vibration working table 100 to reciprocate along the X direction. During this process, the first slideway 1 moves together, and the first slider 11 relieves the movement interference of the first slideway 1 on it through sliding; the vibration from the vertical Z-direction exciter will drive the vibration working table 100 to reciprocate along the Z direction. During this process, the first slideway 1, the first slider 11 and the connected second slider 21 all move together, and the second slideway 2 relieves the movement interference of the second slider 21 on it through sliding, so that the connecting transition plate 4 and the horizontal Y-direction exciter on it are not affected by the exciters in the other two directions. When the horizontal Y-direction exciter is not needed, disconnect its connection with the vibration working table 100 by removing the cross adapter block 3 and the pin to avoid restricting the Y-direction movement of the vibration working table 100.
[0032] Embodiment 2:
[0033] As Figure 3 and Figure 4 shown in the figure, the difference from Embodiment 1 is that the first slideway 1 is arranged perpendicular to the side of the vibration working table 100, and its setting direction is the same as the vibration direction of the vertical Z-direction exciter; while the setting direction of the second slideway 2 is the same as the vibration direction of the horizontal X-direction exciter. This design is applicable to the test with a short Z-direction movement stroke and a large X-direction vibration stroke.
[0034] Embodiment 3:
[0035] The difference from Embodiment 1 is that both the first slideway 1 and the second slideway 2 are chute structures, and slide rail structures corresponding to the chutes are arranged on the first slider 11 and the second slider 21.
[0036] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
