Technical Field

[0001] This utility model relates to the field of experimental equipment technology, and in particular to a vibration fixture and vibration platform. Background Technology

[0002] The rapid development of the experimental equipment industry has also driven the rapid development of vibration testing equipment. In order to ensure that the components formed by wire harnesses to form connecting circuits can withstand the test of various vibration environments in actual use and ensure their stability and reliability, reliability testing must be carried out, and vibration testing is one of them.

[0003] Currently, there are numerous types and models of wire harnesses. In traditional technology, vibration testing of wire harnesses of different sizes or models requires the production of vibration fixtures that are adapted to them, resulting in significant resource waste and increased testing costs. Existing technologies offer vibration fixtures that can be adjusted to a certain extent, but most have complex structures, and their fixation effect is difficult to guarantee. Utility Model Content

[0004] Therefore, it is necessary to provide a vibration fixture and vibration platform that can be adapted to different types of wire harnesses to address the above problems.

[0005] To address the above problems, this application provides the following technical solution:

[0006] A vibration fixture is used on a vibration table. The vibration table has multiple mounting positions. The vibration fixture includes at least two fixing devices. Each fixing device includes a base, a vertical frame, and a support frame. The length direction of the vertical frame is the Z-axis direction, and the vertical frame is movably mounted on the base along a first direction. The length direction of the support frame is parallel to the first direction, and the support frame is adjustablely mounted on the vertical frame along the length direction of the vertical frame. Each fixing device can be adjustablely mounted on the mounting position along a second direction. The first direction is either the X-axis direction or the Y-axis direction, and the second direction is the other one.

[0007] This configuration allows the vibration fixture to be adjusted simultaneously in the first direction, the second direction, and the Z-axis direction, meeting the testing requirements of wire harnesses of different sizes or types.

[0008] In one embodiment, each fixing device includes a reinforcing frame fixed to a base, the reinforcing frame having a stabilizing portion located above the base, one end of the upright being movably disposed on the base, and the other end being movably disposed on the stabilizing portion.

[0009] This configuration satisfies the spatial structural stability of the fixing device while also enabling adjustment in the first direction.

[0010] In one embodiment, the reinforcing frame includes a connecting portion, the base includes an adjusting portion and a fixing portion spaced apart from the adjusting portion, one end of the connecting portion is fixed to the fixing portion, and the other end is fixed to the stabilizing portion.

[0011] This design connects the reinforcing frame and the base into a single unit, making the connection between the upper and lower parts of the fixing device more secure.

[0012] In one embodiment, the reinforcing frame includes reinforcing ribs, with a fixing part and a connecting part fixedly connected to each end of the reinforcing ribs, respectively. This arrangement provides support to the sides of the reinforcing frame, effectively reducing the possibility of structural side damage during testing.

[0013] In one embodiment, the adjusting part is provided with a first adjusting hole, the stabilizing part is provided with a second adjusting hole, and the two ends of the upright are respectively provided with a third adjusting hole that connects the first adjusting hole and the second adjusting hole through fasteners.

[0014] This configuration achieves a tight connection between the upright and the fixing device, while also allowing the upright to be adjusted in the first direction.

[0015] In one embodiment, the opening direction of the first adjustment hole is along the Z-axis, and the opening direction of the second adjustment hole is along a direction perpendicular to the X-axis or the Y-axis.

[0016] This design makes the force transmission path of the support frame in the fixing device more reasonable, and avoids the fasteners bearing large shear forces.

[0017] In one embodiment, along the Z-axis, the side of the support frame has multiple spaced fourth adjustment holes, and the support frame has fifth adjustment holes that are adjustablely connected to the fourth adjustment holes via fasteners. This arrangement enables the support frame to be adjustable in the Z-axis direction, allowing the fixing device to meet the vibration testing requirements of wire harnesses at different heights.

[0018] In one embodiment, each fixing device includes at least one support frame, which is disposed on one or both sides of the upright. This arrangement allows one fixing device to simultaneously support and fix multiple sets of wire harnesses and perform vibration tests on multiple sets of wire harnesses at the same time.

[0019] In one embodiment, the support frame is provided with a plurality of sixth adjustment holes spaced apart along the length of the support frame. This arrangement allows the support frame to provide fixed support for wire harnesses of different sizes.

[0020] In one embodiment, the base is further provided with a seventh adjustment hole; the mounting position is a mounting hole, and the seventh adjustment hole is used to adjustably position the device within the mounting hole using fasteners. This arrangement allows the base of the fixing device to be connected and fixed to the mounting hole on the vibration table, thereby enabling the fixing device to be adjustablely positioned on the vibration table.

[0021] This application also provides a vibration platform for testing wire harnesses, including a vibration table and the vibration fixture described in any of the above embodiments. The vibration table has multiple mounting positions, and each fixing device is adjustablely mounted at a mounting position. This arrangement allows the vibration fixture to be adjustablely mounted on the vibration table, thereby enabling the vibration fixture to meet the vibration testing requirements of wire harnesses of different lengths in a second direction.

[0022] Compared with existing technologies, the aforementioned vibration fixture achieves varying degrees of adjustment in three dimensions through the configuration of a base, upright frame, and support frame, enabling it to adapt to vibration testing of wire harnesses of different sizes or types. The reinforcing frame ensures the connection between the components in the fixing device, thereby guaranteeing the fixing effect of the device during vibration testing. Attached Figure Description

[0034] See Figures 1-3 This embodiment provides a vibration fixture for a vibration table 2. The vibration table 2 has multiple mounting positions 20. The vibration fixture includes at least two fixing devices 1. Each fixing device 1 includes a base 11, a stand 12, and a support frame 13. The length direction of the stand 12 is the Z-axis direction, and the stand 12 is movably mounted on the base 11 along the first direction. The length direction of the support frame 13 is parallel to the first direction, and the support frame 13 is adjustablely mounted on the stand 12 along the length direction of the stand 12. Each fixing device 1 can be adjustablely mounted on the mounting position 20 along a second direction. The first direction is either the X-axis direction or the Y-axis direction, and the second direction is the other one.

[0035] It is worth mentioning that at least two fixing devices 1 can form a group; in other words, a group of fixing devices 1 includes at least two fixing devices 1. (Refer to...) Figure 1 As shown, the vibration table 2 is equipped with two sets of fixing devices 1, and each set of fixing devices 1 has two parts.

[0036] For details, please refer to Figure 1 As shown, the vibration table 2 is square, with its four sides extending along the X-axis and Y-axis directions respectively. The vibration table 2 has multiple mounting positions 20, and two fixing devices 1 are arranged along the Y-axis direction of the vibration table 2. When any vibration device is adjusted along the Y-axis direction, the distance between the two fixing devices 1 can be adjusted, thus accommodating wire harnesses 100 of different lengths. On the other hand, since the two fixing devices 1 are arranged along the Y-axis direction, the support frame 12 can be movable relative to the base 11 along the X-axis direction, thereby achieving adjustment in the X-axis direction to accommodate different types of wire harnesses 100. Furthermore, when it is necessary to adjust the height of the support frame 13, since the support frame 13 is movably mounted on the support frame 12, it can be adjusted simply along the height direction of the support frame 12. Through the above-described configuration, the vibration fixture of this application can achieve adjustment of the support frame 13 along the X-axis, Y-axis, and Z-axis directions to accommodate different types or sizes of wire harnesses 100, which is convenient and quick.

[0037] Similarly, in other embodiments, the two fixing devices 1 can also be arranged along the X-axis. The specific adjustment method can refer to the above-described method of arranging the two fixing devices 1 along the Y-axis, and will not be repeated here. Of course, in other embodiments, multiple sets of fixing devices 1 can also be arranged simultaneously in the X-axis and Y-axis directions on a vibration table 2.

[0038] refer to Figure 1 and Figure 2 As shown, each fixing device 1 may also include a reinforcing frame 14, which is fixed to the base 11. The reinforcing frame 14 has a stabilizing part 140 located above the base 11. One end of the upright frame 12 is movably disposed on the base 11, and the other end is movably disposed on the stabilizing part 140. Thus, the two ends of the upright frame 12 are movably connected to the base 11 and the stabilizing part 140, respectively. When adjusting the upright frame 12, the upper and lower ends of the upright frame 12 can be fixed respectively, which has the effect of stabilizing the upright frame 12 and preventing the upright frame 12 from shaking during testing because only one end of the upright frame 12 is movably fixed.

[0039] Specifically, the length direction of the upright 12 is the Z-axis direction, the length of the reinforcing frame 14 along the Z-axis direction is equal to the length of the upright 12, the stabilizing part 140 in the reinforcing frame 14 is located above the base 11, the length direction of the stabilizing part 140 is the X-axis direction, one end of the upright 12 is movably disposed on the base 11 along the X-axis direction, and the other end is movably disposed on the stabilizing part 140 along the X-axis direction.

[0040] In this embodiment, the reinforcing frame 14 includes a connecting portion 141, and the base 11 includes an adjusting portion 110 and a fixing portion 111 spaced apart from the adjusting portion 110. One end of the connecting portion 141 is fixed to the fixing portion 111, and the other end is fixed to the stabilizing portion 140. Specifically, the adjusting portion 110 is disposed on the base 11 along the X-axis direction, and the fixing portion 111 is disposed on the base 11 parallel to the adjusting portion 110 and spaced apart. The connecting portion 141 of the reinforcing frame 14 is an L-shaped structure with a rectangular cross-section, one end of which is fixed to the fixing portion 111, and the other end of which is fixed to the stabilizing portion 140. This arrangement positions the stabilizing portion 140 directly above the adjusting portion, ensuring that the upright frame 12 is arranged along the Z-axis direction.

[0041] refer to Figure 2 As shown, the connecting portion 141 is generally L-shaped. In other embodiments, each stabilizing portion 140 can be fixedly connected by multiple connecting portions 141 to improve the connection strength. The cross-section of the connecting portion 141 can be other shapes, and the connecting portion 141 does not have to be L-shaped, as long as one end can be fixed to the fixing portion 111 and the other end can be fixed to the stabilizing portion 140.

[0042] To further enhance the connection strength between the connecting part 141 and the base 11, the reinforcing frame 14 may also include reinforcing ribs 142, with the two ends of the reinforcing ribs 142 respectively fixedly connected to the fixing part 111 and the connecting part 141. The reinforcing ribs 142 may be provided on one or both sides of the connecting part 141, and one or more reinforcing ribs 142 may be provided on one side of the connecting part 141, which can be set according to requirements.

[0043] In this embodiment, the adjusting part 110 is provided with a first adjusting hole 4, the stabilizing part 140 is provided with a second adjusting hole 5, and both ends of the upright frame 12 are respectively provided with a third adjusting hole 6 that connects the first adjusting hole 4 and the second adjusting hole 5 through fasteners 3, so as to realize the quick and easy adjustment of the upright frame 12 along the length direction of the adjusting part 110. The first adjusting hole 4, the second adjusting hole 5 and the third adjusting hole 6 can be smooth holes or threaded holes, and the adjustment is achieved by fasteners 3, which is convenient and quick.

[0044] To further improve the stability of the connection between the column and the base 11, in this embodiment, the opening direction of the first adjustment hole 4 is along the Z-axis, and the opening direction of the second adjustment hole 5 is along a direction perpendicular to the X-axis or the Y-axis. The perpendicularity of the opening directions of the two adjustment holes makes the force transmission path of the frame 12 in the fixing device 1 more reasonable, thereby reducing possible shaking of the frame 12 during testing. For example, the opening direction of the first adjustment hole 4 is along the Z-axis, and the opening direction of the second adjustment hole 5 is along a direction perpendicular to the X-axis.

[0045] To enable the adjustability of the support frame 13 and the upright frame 12, multiple spaced fourth adjustment holes 7 are provided on the side of the upright frame 12 along the Z-axis. The support frame 13 is provided with a fifth adjustment hole 8 that is adjustablely connected to the fourth adjustment holes 7 via fasteners 3, allowing for quick and easy adjustment of the support frame 13 along the length of the upright frame 12. The fourth adjustment holes 7 and the fifth adjustment holes 8 can be either smooth holes or threaded holes, and adjustment is achieved through the fasteners 3, making it convenient and quick.

[0046] In this embodiment, each fixing device 1 includes a support frame 13, which is arranged on one side of the upright frame 12.

[0047] In other embodiments, each fixing device 1 may also include multiple support frames 13, all of which are adjustablely mounted on the upright frame 12. The multiple support frames 13 may be located on the same side of the upright frame 12 or on both sides of the upright frame 12. When the multiple support frames 13 are located on both sides of the upright frame 12, the support frames 13 on both sides may be symmetrically arranged relative to the upright frame 12 or staggered; no limitation is made here.

[0048] It is worth mentioning that the support frame 13 is provided with a plurality of sixth adjustment holes 9 spaced apart along the length of the support frame 13. The support frame 13 is used to support and fix the wire harness 100. Specifically, the support frame 13 is provided with a plurality of sixth adjustment holes 9 arranged along the length of the support frame 13. On the one hand, the wire speed can be fixed by fasteners 3 or cable ties, and on the other hand, the wire speed can be finely adjusted by adjusting the wire speed at different positions of the support frame 13.

[0049] Specifically, the support frame 13 is a sheet-like structure with an L-shaped cross-section, and the sixth adjustment holes 9 are spaced apart along the length of the support frame 13. In other embodiments, the cross-section of the support frame 13 may not be L-shaped, nor may it be a sheet-like structure, as long as the sixth adjustment holes 9 are spaced apart along the length of the support frame 13.

[0050] In this embodiment, the base 11 is also provided with a seventh adjustment hole 10; the mounting position 20 is a mounting hole, and the seventh adjustment hole 10 is adjustablely positioned within the mounting hole by means of a fastener 3. Two seventh adjustment holes 10 are provided at intervals on each side of the base 11, and the seventh adjustment holes 10 are adjustablely positioned within the mounting holes by means of fasteners 3. By cooperating with the mounting holes, the positional relationship between the fixing device 1 and the vibration table 2 can be adjusted along the X-axis or Y-axis, thereby achieving adaptation to different lengths of the wire harness 100.

[0051] In this embodiment, a vibration platform is also provided for testing the wire harness 100, including a vibration table 2 and the vibration fixture described in any of the above embodiments. The vibration table 2 is provided with a plurality of mounting positions 20, and each fixing device 1 is adjustablely disposed at the mounting position 20.

[0052] Specifically, the vibration fixture and the vibration table 2 can be combined to perform vibration tests on the wire harness 100. The vibration table 2 is provided with multiple mounting positions 20. Every two fixing devices 1 are arranged and used in combination along the X-axis or Y-axis. Each fixing device 1 is adjustable along the Y-axis and is located at the mounting position 20 to meet the testing of different models of wire harness 100. The vibration platform is easy and quick to adjust.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
