Description

Technical Field

[0001] The utility model relates to the technical field of testing, in particular to a vibration testing tool. Background Art

[0002] Currently, many sensors, precision components, and precision equipment require X, Y, and Z axis vibration testing to comprehensively test and evaluate their performance. Currently, there are two types of vibration test fixtures commonly used:

[0003] (1) A single vibration test fixture can only test one of the X, Y, and Z axes. The other two axes need to be replaced with another vibration test fixture to install the device under test for vibration testing. This results in the need to use three special vibration test fixtures, the vibration test cost is high, and the vibration test process is troublesome to disassemble and assemble, resulting in low test efficiency.

[0004] (2) Use an integrated X, Y, and Z-axis vibration test fixture (for example, a cross-shaped vertical plate is set on a flat plate to form X, Y, and Z-axis direction partitions). The device under test is installed on the corresponding axis direction partition for the axis vibration test to be performed, or the X, Y, and Z-axis vibration tests are performed on the device under test at the same time. This results in the single-axis vibration test being hindered by the installation structure of the other two axes (for example, when the device under test is installed on the Z-axis direction partition, i.e., the flat plate, the vibration is hindered by the cross-shaped vertical plate or the vibration is uneven), resulting in inaccurate vibration test results. It also results in inaccurate vibration frequency and uneven vibration when the X, Y, and Z axes are vibrated simultaneously due to the excessive weight of the fixture itself and the obstruction of the installation structure, which also makes the vibration test results inaccurate.

[0005] Therefore, there is an urgent need for a vibration test fixture with a simple structure that can accurately perform separate tests on the X, Y or Z axis. Utility Model Content

Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0036] The following combination Figures 1 to 5 , describing a vibration testing tooling of an embodiment of the present utility model.

[0037] A vibration test fixture includes a plate 1, an X-axis assembly 2, a Y-axis assembly 3, and a Z-axis assembly 4. Multiple devices under test 5 can be mounted in the center of the front or rear of the plate 1. X-axis test mounting positions 11, Y-axis test mounting positions 12, and Z-axis test mounting positions 13 are staggered around the circumference of the plate 1.

[0038] When the device under test 5 is subjected to an X-axis vibration test, the X-axis assembly 2 is installed between the X-axis test installation position 11 and the vibration test platform 6, and the plate 1 is erected in the X-axis direction;

[0039] When the device under test 5 is subjected to a Y-axis vibration test, the Y-axis assembly 3 is installed between the Y-axis test installation position 12 and the vibration test platform 6, and the plate 1 is erected in the Y-axis direction;

[0040] When the device under test 5 is subjected to a Z-axis vibration test, the Z-axis assembly 4 is installed between the Z-axis test installation position 13 and the vibration test platform 6 , and the plate 1 is erected horizontally in the Z-axis direction.

[0041] The present invention proposes a preferred embodiment of a vibration test tool, such as Figures 1 to 5 As shown, the vibration test fixture realizes separate testing of the X, Y, and Z axes by designing the structure of the flat plate 1, X-axis assembly 2, Y-axis assembly 3, and Z-axis assembly 4 and their mutual coordination. Among them, the flat plate 1 serves as the main structure, and multiple devices under test 5 can be installed in the center of the front or back to provide a basic platform for testing; the X, Y, and Z axis test installation positions staggered around the side of the flat plate 1 allow the test components of the three axes to be installed separately, avoiding mutual interference and convenient disassembly and assembly; and the X-axis assembly 2, Y-axis assembly 3, and Z-axis assembly 4 are used for vibration testing of the X, Y, and Z axes respectively. During each test, only the components of the corresponding axis are installed, and the flat plate 1 is erected in the direction of the corresponding axis so that the device under test 5 is in the correct test direction. This design ensures that during each test, only the components of one axis are connected to the vibration test platform, avoiding the influence of the installation structures of other axes on the test, thereby improving the accuracy of the test results.

[0042] Specifically, the flat plate 1 is divided into a front panel, a rear panel, a left side, a right side, an upper side and a lower side, wherein the front panel and the rear panel are mounting surfaces for the device under test 5, the lower side is the X-axis fitting plane, the left side or the right side is the Y-axis opposite surface, and the rear panel is the Z-axis opposite surface; the Y-axis assembly 3 and the X-axis assembly 2 are respectively detachably mounted on the Y-axis opposite surface, and the Z-axis assembly 4 is detachably mounted on the Z-axis opposite surface, thereby realizing X-, Y- and Z-axis vibration tests respectively.

[0043] It should be noted that the peripheral side of the plate 1 generally refers to the area except for the front or rear center of the plate 1 for mounting the device under test 5. Within this range, the top surface, bottom surface, side surface or interior of the plate 1, etc., and any way of setting the X-axis test mounting position, Y-axis test mounting position or Z-axis test mounting position are all within the limited range.

[0044] This technical solution achieves independent single-axis testing of the X, Y, and Z axes through the installation of detachable components and the adjustment of the direction of the plate 1. It solves the problem of mutual interference between multi-axis structures in traditional vibration test fixtures and ensures the independence and accuracy of each axis test. At the same time, the design has a simple structure and is easy to disassemble and assemble, which improves testing efficiency. In addition, since three-axis testing can be performed on the same plate 1, the need for tooling replacement is reduced, reducing testing costs.

[0045] Furthermore, the X-axis test installation position 11 is set at the corner of the tablet 1; the Y-axis test installation position 12 is set in the middle of the side of the tablet 1; the Z-axis test installation position 13 is set in the middle of the side of the tablet 1 and is staggered with the Y-axis test installation position 12.

[0046] In this embodiment, the problem of performing multi-directional vibration testing on a flat panel is solved by rationally arranging the X-axis, Y-axis, and Z-axis test mounting positions. The X-axis test mounting position 11 is arranged at the corner of the flat panel 1, which can provide a stable support point for the flat panel 1, making it easy to lift the flat panel 1 in the X-axis direction, which is beneficial to the transmission of vibration in the X-axis direction. Similarly, the Y-axis test mounting position 12 and the Z-axis test mounting position 13 are both arranged in the middle of the side, which can provide a stable support point for the flat panel 1. However, the Y-axis test mounting position 12 and the Z-axis test mounting position 13 are staggered with each other. This arrangement can make full use of the space around the flat panel 1 to achieve vibration testing in different axes.

[0047] It should be noted that, based on the limitation of the circumferential range, the corners of the flat plate 1 generally refer to the raised parts of the flat plate 1 regardless of whether the flat plate 1 is rectangular, square, triangular or polygonal; and the middle part of the side of the flat plate 1 generally refers to the area between the two corners.

[0048] Furthermore, a recessed platform with a fixing hole is provided at the lower left or right corner or the upper left or right corner of the flat plate 1 to form an X-axis test mounting position 11;

[0049] A groove with a fixing hole is provided in the middle of the side of the flat plate 1 to form a Y-axis test mounting position 12;

[0050] Fixing holes are opened in the middle of the left and right sides of the flat plate 1 to form a Z-axis test installation position 13.

[0051] In this embodiment, considering the different directions in which the tablet 1 is erected during the X-axis, Y-axis, and Z-axis vibration tests, it is necessary to maintain the structural strength and stability of the tablet 1 after it is erected. Therefore, the X-axis test mounting position 11 adopts a concave platform structure with a fixing hole, the Y-axis test mounting position 12 adopts a groove structure with a fixing hole, and the Z-axis test mounting position 13 adopts a fixed hole structure.

[0052] Among them, because the X-axis test mounting position 11 is to be set at the corner of the flat plate 1 and the flat plate 1 needs to be erected, a recessed platform structure with fixing holes is provided at the lower left or right corner or the upper left or right corner of the flat plate 1. After the X-axis assembly 2 is fixed on the recessed platform using the fixing holes, when the flat plate 1 is erected in the X-axis direction, the X-axis assembly 2 provides an upward supporting force for the recessed platform to support the flat plate 1 to be erected stably in the X-axis direction, thereby preventing the flat plate 1 from losing balance or becoming structurally unstable.

[0053] Because the Y-axis test mounting position 12 is set in the middle of the side of the tablet 1, and the tablet 1 needs to be erected, a groove structure with a fixing hole is adopted to allow the Y-axis component 3 to be fixed in the groove through the fixing hole, and to have a large contact area and a firm limiting relationship with the tablet 1, so that when the tablet 1 is erected in the Y-axis direction, the Y-axis component 3 provides an upward supporting force for the groove to support the tablet 1 to be stably erected in the Y-axis direction, thereby preventing the tablet 1 from losing balance or becoming structurally unstable.

[0054] Because the Z-axis test mounting position 13 is set in the middle of the side of the tablet 1 and is horizontally erected in the Z-axis direction, the Z-axis component 4 only needs to provide supporting force to horizontally erect the tablet 1. Therefore, a fixed hole structure (consisting of at least one fixed hole) is opened in the middle of the left and right sides of the tablet 1 for fixedly installing the Z-axis component 4 to support the tablet 1 to be stably erected horizontally in the Z-axis direction to prevent the tablet 1 from losing balance or structural instability.

[0055] Furthermore, the X-axis assembly 2 includes two L-shaped angle brackets 21, which are respectively mounted on two concave platforms of the X-axis test mounting position 11;

[0056] One end of the L-shaped angle code 21 is placed in the recess of the X-axis test mounting position 11 and is fixedly connected to the X-axis test mounting position 11 through the fixing hole of the X-axis test mounting position 11. The other end of the L-shaped angle code 21 is fixedly connected to the vibration test platform 6.

[0057] In this embodiment, based on the X-axis vibration test, the flat plate 1 is erected in the X-axis direction through a concave platform with a fixing hole. In order to simplify the component structure, reduce the difficulty of disassembly and assembly, and improve the test efficiency, the X-axis component 2 is preferably composed of two L-shaped angle brackets 21, and the two L-shaped angle brackets 21 are respectively installed on the two concave platforms of the X-axis test installation position 11; wherein, one end of the L-shaped angle bracket 21 is placed in the concave platform of the X-axis test installation position 11, and is fixedly connected to the X-axis test installation position 11 through the fixing hole of the X-axis test installation position 11, and the other end of the L-shaped angle bracket 21 is fixedly connected to the vibration test platform 6, thereby erecting the flat plate 1 in the X-axis direction. Figure 3 shown.

[0058] Furthermore, the Y-axis assembly 3 is a horizontal plate, the middle part of the Y-axis assembly 3 is embedded in the groove of the Y-axis test mounting position 12, and is fixedly connected to the Y-axis test mounting position 12 through the fixing hole of the Y-axis test mounting position 12. The front and rear ends of the Y-axis assembly 3 are fixedly connected to the vibration test platform 6, and the Y-axis assembly 3 and the plate 1 are perpendicular to each other.

[0059] In this embodiment, based on the Y-axis vibration test, the flat plate 1 is erected in the Y-axis direction through the groove with the fixing hole. In order to simplify the component structure, reduce the difficulty of disassembly and assembly, and improve the test efficiency, the Y-axis component 3 is preferably composed of a horizontal plate, and the middle part of the horizontal plate is embedded in the groove of the Y-axis test installation position 12, and is fixedly connected to the Y-axis test installation position 12 through the fixing hole of the Y-axis test installation position 12. The front and rear ends of the horizontal plate are fixedly connected to the vibration test platform 6, so that the Y-axis component 3 and the flat plate 1 are perpendicular to each other, thereby erecting the flat plate 1 in the Y-axis direction. Figure 4 shown.

[0060] Furthermore, the Z-axis assembly 4 includes two Z-shaped angle brackets 41, and the two Z-shaped angle brackets 41 are respectively installed in two fixing holes of the Z-axis test installation position 13;

[0061] One end of the Z-shaped angle code 41 is fixedly connected to the Z-axis test installation position 13 through a fixing hole of the Z-axis test installation position 13 , and the other end of the Z-shaped angle code 41 is fixedly connected to the vibration test platform 6 .

[0062] In this embodiment, based on the Z-axis vibration test, the plate 1 is horizontally erected in the Z-axis direction through the groove with the fixing hole. In order to simplify the component structure, reduce the difficulty of disassembly and assembly, and improve the test efficiency, the Z-axis component 4 is preferably composed of two Z-shaped angle brackets 41, and the two Z-shaped angle brackets 41 are respectively installed in the two fixing holes of the Z-axis test installation position 13; wherein, one end of the Z-shaped angle bracket 41 is fixedly connected to the Z-axis test installation position 13 through the fixing hole of the Z-axis test installation position 13, and the other end of the Z-shaped angle bracket 41 is fixedly connected to the vibration test platform 6, thereby horizontally erecting the plate 1 in the Z-axis direction, as shown in FIG. Figure 5 shown.

[0063] Furthermore, a plurality of DUT mounting positions 7 are provided in the center of the front or rear of the plate 1 . The plurality of DUT mounting positions 7 are aligned from top to bottom and from left to right, and each DUT mounting position 7 is provided with a DUT 5 .

[0064] In this embodiment, the vibration test tooling can also be used for data calibration of the device under test 5. By aligning multiple devices under test 5 arranged in the center of the front or rear of the flat plate 1 horizontally and vertically, the influencing factors during the vibration process are reduced. Thus, the data of all devices under test 5 are received simultaneously during the vibration process for comparison to determine which device under test 5 has inaccurate data, and then the device under test 5 is calibrated.

[0065] It should be noted that the device under test mounting position 7 can be a screw hole, and the screw passes through the screw hole in the center of the device under test 5 and the screw hole of the device under test mounting position 7 to fix the device under test 5 on the flat plate 1; the device under test mounting position 7 can also be a limit slot or other structure, which is not limited here.

[0066] Furthermore, a first elongated fixing through hole 211 is formed at the other end of the L-shaped angle bracket 21 , and the first elongated fixing through hole 211 is used for connecting to the vibration test platform 6 .

[0067] Furthermore, a second elongated fixing through hole 31 is provided at both the front and rear ends of the Y-axis assembly 3 , and the second elongated fixing through hole 31 is used to connect to the vibration test platform 6 .

[0068] Furthermore, a third long strip fixing through hole 411 is formed at the other end of the Z-shaped angle code 41 , and the third long strip fixing through hole 411 is used for connecting to the vibration test platform 6 .

[0069] In this embodiment, based on the different vibration test platforms 6 installed on the vibration test tooling, the vibration test tooling may not be able to adapt to the installation of the vibration test platform 6. Therefore, a first long strip fixing through hole 211 is provided at the other end of the L-shaped angle code 21, a second long strip fixing through hole 31 is provided at both the front and rear ends of the Y-axis assembly 3, and a third long strip fixing through hole 411 is provided at the other end of the Z-shaped angle code 41. By utilizing the structure of the long strip through holes, the installation position can be freely adjusted when connected to the vibration test platform 6, so that the vibration test tooling is suitable for more vibration test platforms 6.

[0070] It should be noted that the connection relationship between the first elongated fixing through hole 211, the second elongated fixing through hole 31 and the third elongated fixing through hole 411 and the vibration test platform 6 respectively can be a connection relationship formed by a screw passing through the fixing through hole and the through hole opened in the vibration test platform 6 and cooperating with a nut; or it can be a connection relationship formed by a screw rod passing through the fixing through hole and cooperating with a nut on the vibration test platform 6; as long as any method can connect the first elongated fixing through hole 211, the second elongated fixing through hole 31 and the third elongated fixing through hole 411 to the vibration test platform 6 respectively, it falls within the limited range.
