Description

Technical Field

[0001] The present invention relates to the field of automobiles, and particularly to a modular vibration tooling used during vehicle vibration testing. Background Art

[0002] Vibration is a very common motion phenomenon in nature, and it exists very widely in engineering technology and daily life. From large-scale earthquakes, winds, and tsunamis to small-scale vibrations of strings, tuning forks, and pendulums, they can all be classified as vibrations. However, although vibration is ubiquitous in nature, in many cases, vibration is harmful. It is often the direct cause of mechanical and structural damage and failure.

[0003] Precisely because of this, the anti-vibration performance of structures has always been an important issue concerned in structural design. Correspondingly, for automobile manufacturers, vibration testing is one of the important tests that all components must complete. In order to make the vibration test as close as possible to the real vehicle environment so as to reflect as accurately as possible the vibration conditions of components under driving conditions, the vibration standards of automobile manufacturers usually require that the installation direction and installation method of the test piece be the same as those of the real vehicle. Then, in order to meet the above requirements, obviously the test piece cannot be directly installed on the vibration table. The test piece needs to be installed on a tooling that can restore the installation direction and installation method of the real vehicle for testing. At this time, the control point for applying excitation needs to be set on the tooling and as close as possible to the installation connection point between the test piece and the tooling.

[0004] For most components, the number of installation points connected to the vehicle body is more than 1, and correspondingly, the number of installation points with the tooling is also more than 1. At this time, if the response differences of each installation point are large, then the natural frequency of the test piece under the constrained state will change, and at the same time, the actual excitation received by the test piece will deviate from the control excitation. Whether the actual excitation is too small or too large is not conducive to accurately evaluating the anti-vibration performance of the test piece: if the actual excitation is too small, it will cause the test piece to undergo a vibration test in a relatively safe situation compared to the actual working condition, which will bring potential risks to the future use of the component; if the actual excitation is too large, it will cause the test piece to undergo a vibration test in a more severe situation compared to the actual working condition, thus increasing the difficulty of passing the vibration test and causing serious over-design, which may result in additional time, manpower, and manufacturing costs for component manufacturers.

[0005] A vibration table generally consists of a vibration table (table body), a moving coil base of the vibration table, a moving coil of the vibration table, trunnions, air springs, trunnions and other auxiliary accessories. A pair of trunnions are installed in the mounting holes inside the vibration table (table body). The moving coil base of the vibration table is connected to the trunnions through 4 guide rails. At the same time, 4 air springs are sandwiched between the moving coil base of the vibration table and the trunnions. The moving coil of the vibration table is installed in the moving coil base of the vibration table. There are two sets of exciting coils in the moving coil base of the vibration table, and the exciting coils are connected to a power amplifier through cables. After being powered on, the host computer transmits the vibration spectrum to be generated to the vibration controller, and the vibration controller controls the up and down movement of the moving coil of the vibration table in the moving coil base of the vibration table by controlling the power amplifier, so as to generate vibrations that conform to the target spectrum, such as Figure 1 , Figure 2 .

[0006] According to current international standards, national standards or enterprise standards, vibration tests generally include vibration tests and mechanical shock tests. It is necessary to complete vibration or mechanical shock tests in three axial directions of the installation posture of the test sample. In daily tests, relevant tests are completed by switching the directions of the moving coil base and the moving coil of the vibration table: when the moving coil base and the moving coil of the vibration table are in the vertical direction, vibration or mechanical shock tests in the vertical axial direction are carried out; when the moving coil base and the moving coil of the vibration table are in the horizontal direction, vibration or mechanical shock tests in two horizontal axial directions are carried out, such as Figure 1 and Figure 3 .

[0007] Taking a certain brand and model of vibration table as an example, the top of the moving coil of this type of vibration table is a radially convex platform threaded hole base with a height of about 30 mm, such as Figure 4 , Figure 5 . Due to the size limitation of the installation threaded holes of the moving coil of the vibration table, in order to match more test samples, the manufacturer also configures a vertical table extension platform when the vibration table leaves the factory, such as Figures 6 - 10 .

[0008] Currently, the products that need to undergo vibration tests are diverse, and the products (test samples) need to design suitable vibration toolings during the vibration test process, such as Figures 11 - 16 . However, the number of vibration test tables in each unit is limited, and the types and specifications are mostly fixed and unified. Therefore, for each vibration test, as long as the product size changes, a different set of suitable vibration toolings needs to be designed. Through the vibration tooling, the test sample to be measured is installed on the vibration table. The current method results in a large variety and quantity of vibration toolings. Even more puzzling is that even if there is a slight change in the installation size of the test sample to be measured, a new vibration tooling has to be redesigned, and simulation calculations are required each time a new tooling is designed to ensure that the installation stiffness of the tooling meets the test requirements, thus consuming a large amount of manpower and material resources. The storage of a large number of vibration toolings is also a new problem.

[0009] Vibration tests generally need to be carried out for vibrations and mechanical shock tests in three axes (X, Y, Z). The current practice requires switching the direction of the moving coil of the vibration table to conduct vibration or shock tests in different axes. Taking a mainstream type of vibration table as an example, when conducting vibration or mechanical shock tests in the vertical axis (Z), the direction of the moving coil of the vibration table needs to be switched to the vertical direction; when conducting vibrations and mechanical shock tests in the horizontal transverse (X) and horizontal longitudinal (Y) directions, the direction of the moving coil of the vibration table needs to be switched to the horizontal direction, as Figures 17 - 25 . High-frequency switching of the direction of the moving coil of the vibration table consumes a large amount of manpower and also exacerbates the wear of the vibration table.

[0010] According to practice, it is known that the stiffness of the vibration tooling is closely related to the mass, the height of the center of gravity, and the concentration of the mass distribution above the center of gravity. The smaller the mass, the lower the center of gravity, and the smaller the mass towards the higher position, the better the stiffness of the tooling. A tooling similar to a short and flat one is the preferred design.

[0011] Since the thrust of the vibration table is provided by the excitation coil, its thrust is constant. According to Newton's second law: F = ma, when the thrust is constant, the smaller the mass of the moving part, the greater the acceleration that the moving coil and the tested tooling can reach, and the wider the test range.

[0012] The current material of the vertical table extension platform is magnesium alloy. Through simulation and actual measurement, the mass of this vertical table extension platform is 84 kg, the top surface height is 205 mm, and the natural frequency is 900 Hz. Since this vertical table extension platform needs to fix itself on the moving coil of the vibration table and also provide mounting holes for installing the test specimens, its shape is an upper extension shape, with a counterbore in the middle for installing itself on the moving coil of the vibration table, and threaded holes are distributed around this counterbore for installing the tested specimens and their tooling. This results in a large mass at the higher position, which is very unfavorable for vibration; the equivalent mass of the horizontal sliding table is 154 kg, and the natural frequency is about 800 Hz. The large mass of the horizontal sliding table is not conducive to high-acceleration vibration or mechanical shock tests.

[0013] Therefore, it is very necessary to design a set of as general as possible three-way vibration tooling and to reduce the installation height of the tested specimen relative to the top of the moving coil as much as possible. Summary of the Invention

[0014] A series of simplified concepts are introduced in the summary of the invention part. These simplified concepts are all simplified from the prior art in this field, which will be further described in detail in the specific implementation part. The summary of the invention part of the present invention does not mean to attempt to define the key features and essential technical features of the claimed technical solution, nor does it mean to attempt to determine the protection scope of the claimed technical solution.

[0015] The technical problem to be solved by the present invention is to provide a modular vibration tooling that can be combined according to the installation requirements and test requirements of the test piece to be tested.

[0016] Correspondingly, the present invention also provides a three-way (three axes X, Y, Z) vibration table with the modular vibration tooling.

[0017] To solve the above technical problem, the modular vibration tooling provided by the present invention is formed by at least one basic component;

[0018] The first basic component includes:

[0019] The first bottom plate, on one side of which a fixing structure for connecting the moving coil of the vibration table is formed, and on the other side of which a connecting structure for connecting other first basic components is formed;

[0020] The column body is formed between the fixing structure and the connecting structure of the first bottom plate of the first basic component, and an installation surface for fixing the test sample installer is formed thereon;

[0021] The second basic component is formed into a frame structure composed of a top beam, a base, a left side wall and a right side wall, and can be fixedly installed between the column bodies of 2 first basic components;

[0022] The third basic component, after 2 third basic components are spliced, has the same shape as the first bottom plate of the first basic component;

[0023] The auxiliary part is used to fixedly connect the tops of the main bodies of at least 2 first basic components.

[0024] Optionally, further improving the modular vibration tooling, it is composed of 4 first basic components, 4 second basic components and 1 auxiliary part;

[0025] The 4 first basic components are arranged in central symmetry, 1 second basic component is fixedly connected between every 2 adjacent first basic components, and 1 auxiliary part is fixedly connected to the tops of the column bodies of the 4 first basic components;

[0026] Among them, the installation surface on the outer side wall of the column body of the first basic component is used to fix the test sample installer.

[0027] Optionally, further improving the modular vibration tooling, it is composed of 2 first basic components, 4 third basic components and 1 auxiliary part;

[0028] The 2 first basic components are arranged in central symmetry, 2 third basic components are fixedly and juxtaposedly connected between the first bottom plates of the 2 first basic components, and 1 auxiliary part is fixedly connected to the tops of the column bodies of the 2 first basic components;

[0030] Optionally, further improve the modular vibration tooling, which is composed of two first basic components, four third basic components and one auxiliary component;

[0031] The two first basic components are arranged adjacent to each other. One third basic component is fixedly connected in parallel between the first bottom plates on one side of the two first basic components, and three third basic components are fixedly connected in parallel between the first bottom plates on the other side. One auxiliary component is fixedly connected to the tops of the columns of the two first basic components;

[0032] Among them, the installation surfaces of the two first basic components are connected to form a flat vertical installation surface for fixing the device under test installer.

[0033] Optionally, further improve the modular vibration tooling, which is composed of three first basic components, two second basic components, two third basic components and one auxiliary component;

[0034] The three first basic components are arranged adjacent to each other in central symmetry. One second basic component is arranged between the smaller included angles of every two first basic components. The two third basic components are arranged in parallel between the first bottom plates of the two first basic components on the outer side. The first bottom plates of the adjacent first basic components and the third basic components are fixed to each other, and the adjacent third basic components are fixed to each other. One auxiliary component is fixedly connected to the tops of the columns of the three first basic components;

[0035] Among them, the included angle between the adjacent installation surfaces of the two first basic components on the outer side is less than 180 degrees, and the adjacent installation surfaces are used to fix the device under test installer.

[0036] Optionally, further improve the modular vibration tooling, which is composed of eight third basic components, and its top surface is used to fix the device under test installer.

[0037] Optionally, further improve the modular vibration tooling. The column is a hollow triangular prism, and its three faces are installation surfaces.

[0038] To solve the above technical problems, the present invention provides a vibration table with the modular vibration tooling, including: the moving coil base of the vibration table is connected to the trunnion through a guide rail. An air spring is arranged between the moving coil base of the vibration table and the trunnion. The moving coil of the vibration table is installed in the moving coil base of the vibration table and is connected to the modular vibration tooling through an extension platform or a horizontal sliding table.

[0039] Optionally, further improve the vibration table of the modular vibration tooling, characterized in that it can be used for vibration tests of electronic control brake system controllers, intelligent electronic control brake system controllers, automotive steering system controllers and assemblies, 4G remote communication modules, 5G remote communication modules, tire pressure sensors, tire pressure controllers, anti-lock braking system controllers and assemblies, vehicle stability control system controllers and assemblies, high-voltage control unit controllers, intelligent system controllers, intelligent camera controllers, and advanced driver assistance controllers.

[0040] Through the combination of three basic components and auxiliary components, the present invention can form a multi-purpose general modular vibration tooling. This modular vibration tooling can form different combinations according to the types and quantities of selected basic components and auxiliary components and is directly installed on the moving coil of the vibration table. The present invention can at least achieve the following technical effects:

[0041] 1. Modular combination: Through the mutual combination of three basic components and auxiliary components, plus several auxiliary components, the present invention forms a set of multi-purpose general vibration tooling. By removing the original extension platform with a height of 205 mm, the volume, mass, and height of the tooling are effectively reduced. For the modality of the tooling, undoubtedly, it can be greatly improved.

[0042] 2. For the general vibration tooling, through modular assembly, when conducting vibration tests on some test samples in the vertical direction, directly use the third basic component for assembly to form an ultra-thin planar mounting base, reducing the relative mounting height of the test sample from 205 mm to 30 mm, reducing the total mass of the basic components from 104 kg to 12.5 kg, further reducing the volume and height of the basic components, improving the stiffness of the basic components, optimizing the overall vibration modality, and expanding the applicable range.

[0043] 3. For the general modular vibration tooling, through modular design, the basic component provides a basic mounting motherboard. Since the stiffness of the basic components in different combination modes has been optimized through simulation calculation, its natural frequency is much higher than the natural frequency of the current "vertical table extension platform" + "vibration tooling" + "test sample". In the actual use process, only the transition tooling (i.e., the test sample installer) between the general modular vibration tooling and the test sample needs to be designed, greatly reducing the task volume of designing the tooling.

[0044] 4. For the general modular vibration tooling, through the mutual combination of each basic component, a basic mounting motherboard is provided, greatly reducing the manufacturing cost of the tooling.

[0045] 5. The universal modular vibration fixture can be assembled into a three-axis fixture through modular assembly. When testing conventional controller products, three-axis vibration tests can be completed in the vertical direction, where the equivalent mass of the vibration table's dynamic coil is minimized, without switching the dynamic coil's direction. This saves a considerable amount of test preparation time and improves work efficiency. Furthermore, the frequency of switching the vibration table's direction is reduced, significantly reducing wear and tear during assembly and disassembly, and extending the vibration table's lifespan. This effectively reduces workload and improves testing efficiency.

[0046] 6. Compared with the three-dimensional cube tooling, the universal modular vibration tooling can reduce the number of modules and change the splicing combination method according to the test requirements, effectively reducing the total mass of the tooling. Under the condition of a certain thrust, the maximum acceleration is increased as much as possible, thereby increasing the test range.

[0047] 7. Reference Figure 26 As shown in the figure, when the universal modular vibration fixture is used to install products in different surfaces of the installation space (such as redundant EPS controllers, etc.), compared with the three-way cube fixture, the modular fixture can select several suitable modules according to the spatial installation angle of the sample during modular installation, reduce the angle between the vertical walls, shorten the length of the cantilever, and increase the stiffness of the test fixture.

[0048] 8. Reference Figure 27 As shown in the figure, compared with the current overall tooling design, the universal modular vibration tooling adopts a standard mounting hole spacing, which reduces the design workload and tooling production cost of the tooling. At the same time, the mounting holes on the base plate can be designed with inclined support arms according to needs, making the tooling design more flexible while maximizing the overall rigidity of the tooling.

[0049] 9. For the installation of assembly types (EPS, XBS, ESC, ABS, etc.), compared with the current single overall tooling design, the universal modular vibration tooling already has a basic upright arm. For different samples, only some relatively designed adaptive tooling is needed for installation, which reduces the design workload and tooling production cost of the tooling.

[0050] 10. When conducting vibration tests on a vibration table in the vertical direction, the universal modular vibration fixture can fully utilize the approximately 30mm height of the vibration table's dynamic coil protruding from the threaded hole base. When the DUT transition fixture (i.e., the DUT installer) is adapted to the universal modular vibration fixture and the DUT, the DUT installation center is moved downward as much as possible, as long as it does not contact the upper surface of the vibration table's dynamic coil. Horizontal installation also utilizes the larger horizontal length of the mounting surface on the column of the first foundation assembly, providing sufficient installation space. This reduces the overall installation height, undoubtedly significantly improving overall rigidity.

[0051] 11. When installing an oversized controller, the modular vibration tooling combines four different basic components to form an oversized vertical facade, which increases the scope of application.

[0052] 12. The universal modular vibration tooling is composed of different basic components to form a motherboard with a "mouth"-shaped installation facade, which is convenient for the normal fixation of certain test samples with protrusions on the installation plane (such as XBS assembly).

[0069] The present invention provides a modular vibration tooling, which is formed by at least one basic component;

[0070] The first basic component includes:

[0071] The first bottom plate, on one side of which a fixing structure for connecting the moving coil of the vibration table is formed, and on the other side of which a connecting structure for connecting to other first basic components is formed;

[0072] The column body is formed between the fixing structure and the connecting structure, and an installation surface for fixing the installer of the sample to be measured is formed thereon;

[0073] Exemplarily, the present invention provides a feasible embodiment of the first basic component, and the corresponding structure should not be construed as a limitation on the first basic component; the first bottom plate is approximately fan-shaped, and the main body is a hollow triangular prism;

[0074] The included angle between side 1 and side 4 of the fan-shaped bottom plate is 90 degrees, and the included angles between side 1 and side 3, and between side 2 and side 4 are also 90 degrees. There are 3 countersunk holes distributed in the direction of side 1, namely countersunk hole 4, countersunk hole 5, and countersunk hole 6. There are also 3 countersunk holes in the direction with an included angle of 45 degrees with side 1, namely countersunk hole 1, countersunk hole 2, and countersunk hole 3. The purpose of designing these 6 countersunk holes is to facilitate the installation of the fan-shaped bottom plate on the boss threaded hole base on the moving coil of the vibration table using hexagon socket head cap screws, as Figures 28 - 32 .

[0075] The triangular column of the hollow triangular prism mounting mother plate of the fan-shaped bottom plate is a hollow structure. The hollow triangular prism is located directly above the fan-shaped bottom plate. The countersunk depths of the 3 countersunk holes inside it are different. The countersunk surfaces of countersunk hole 2, countersunk hole 4, countersunk hole 5, and countersunk hole 6 are in the same plane. The countersunk surfaces of countersunk hole 1 and countersunk hole 3 are above half of the height of the hollow triangular prism. The purpose of such design is: According to calculations, the countersunk surface should be as high as possible, so that the stiffness of the tooling will increase accordingly; and in order to reduce weight as much as possible, the countersunk surfaces of countersunk hole 1 and countersunk hole 3 are above half of the height of the hollow triangular prism. In this way, the countersunk surface of countersunk hole 1 is as high as possible, forming a triangle with the surrounding shorter countersunk surfaces, and its own stiffness is improved as much as possible. Similarly, the same effect can be achieved for countersunk hole 3. As Figures 28 - 31 .

[0076] There are 7 threaded holes on each side of the fan-shaped bottom plate of the hollow triangular prism mounting mother plate where the hollow triangular prism is located. The distances of the 7 threaded holes (threaded hole 1 to threaded hole 7) on the left side in the direction of side 1 and side 3 are the same, which is convenient for installing the transition tooling with standard hole distances; similarly, the distances of the 7 threaded holes (threaded hole 8 to threaded hole 14) on the right side in the direction of side 2 and side 4 are also the same, which is convenient for installing the transition tooling with hole distances, as Figures 37 - 41 .

[0077] There are also 5 threaded holes (threaded hole 15 to threaded hole 19) at the top of the hollow triangular prism of the hollow triangular prism mounting mother plate of the fan-shaped bottom plate, which are used to connect with other basic components, as Figure 32 .

[0078] There are 6 threaded holes (threaded hole 20 to threaded hole 25) on one side of the fan-shaped bottom plate of the hollow triangular prism mounting mother plate where the hollow triangular prism is located; there are 6 countersunk holes (countersunk hole 7 to countersunk hole 12) at the symmetric position on the other side, which are used for splicing multiple hollow triangular prism mounting mother plates of the fan-shaped bottom plate, as Figures 32 - 34 .

[0079] On one side of the fan-shaped bottom plate of the fan-shaped bottom plate hollow triangular column installation mother plate, which is located between the counterbore holes 7 and 12, there are 3 arc-shaped upper convex platforms, namely the first arc-shaped upper convex platform, the second arc-shaped upper convex platform, and the third arc-shaped upper convex platform; on the side of the fan-shaped bottom plate where the threaded holes 20 to 25 are located, there are three arc-shaped lower convex platforms at symmetrical positions with the 3 arc-shaped upper convex platforms, namely the first arc-shaped lower convex platform, the second arc-shaped lower convex platform, and the third arc-shaped lower convex platform. The threaded holes 20 to 25 are located on the three arc-shaped lower convex platforms. Specifically, the threaded holes 20 and 21 are located on the first arc-shaped lower convex platform, the threaded holes 22 and 23 are located on the second arc-shaped lower convex platform, and the threaded holes 24 and 25 are located on the third arc-shaped lower convex platform; the counterbore holes 7 to 12 are located on the three arc-shaped upper convex platforms. Specifically, the counterbore holes 7 and 8 are located on the first arc-shaped upper convex platform, the counterbore holes 9 and 10 are located on the second arc-shaped upper convex platform, and the counterbore holes 11 and 12 are located on the third arc-shaped upper convex platform. The positions of the three arc-shaped upper convex platforms and the three arc-shaped lower convex platforms are completely symmetrical. The positions of the counterbore holes on the arc-shaped upper convex platforms and the positions of the threaded holes on the arc-shaped lower convex platforms are also completely symmetrical. The projections of the three arc-shaped upper convex platforms and the three arc-shaped lower convex platforms on the horizontal plane are the same, as Figures 35 - 36 。

[0080] On the side of the fan-shaped bottom plate of the fan-shaped bottom plate hollow triangular column installation mother plate where there are arc-shaped lower convex platforms, there are also the first arc-shaped convex surface, the second arc-shaped convex surface, and the third arc-shaped convex surface around the counterbore holes 4, 5, and 6. Specifically, the outside of the counterbore hole 4 is the first arc-shaped convex surface, the outside of the counterbore hole 5 is the second arc-shaped convex surface, and the outside of the counterbore hole 6 is the third arc-shaped convex surface. There are also three arc-shaped concave surfaces directly above the three arc-shaped lower convex platforms on the same side, namely: the one directly above the first arc-shaped lower convex platform is the first arc-shaped concave surface, the one directly above the second arc-shaped lower convex platform is the second arc-shaped concave surface, and the one directly above the third arc-shaped lower convex platform is the third arc-shaped concave surface. As Figure 35 、 Figure 36 。

[0081] On the side of the fan-shaped bottom plate of the fan-shaped bottom plate hollow triangular column installation mother plate where there are arc-shaped upper convex platforms, there are also three arc-shaped concave surfaces at symmetrical positions with the 3 arc-shaped convex surfaces, namely the fourth arc-shaped concave surface, the fifth arc-shaped concave surface, and the sixth arc-shaped concave surface. Specifically, the fourth arc-shaped concave surface is completely symmetrical to the first arc-shaped convex surface in the horizontal plane projection, the fifth arc-shaped concave surface is completely symmetrical to the second arc-shaped convex surface in the horizontal plane projection, and the sixth arc-shaped concave surface is completely symmetrical to the third arc-shaped convex surface in the horizontal plane projection. There are also three arc-shaped concave surfaces directly below the three arc-shaped upper convex platforms on the same side. Specifically, the one directly below the first arc-shaped upper convex platform is the seventh arc-shaped concave surface, the one directly below the second arc-shaped upper convex platform is the eighth arc-shaped concave surface, and the one directly below the third arc-shaped upper convex platform is the ninth arc-shaped concave surface. The purpose of setting these arc-shaped surfaces is to be able to engage and join with each other during modular splicing and form a whole through the connection of bolts, asFigure 35 , Figure 36 。

[0082] The counterbore diameter of the counterbore 2 on the hollow triangular column of the sector bottom plate hollow triangular column installation mother plate is relatively large, and the counterbore surface is on the same horizontal plane as the counterbore surfaces of the counterbore 4, counterbore 5, and counterbore 6, with the aim of minimizing weight as much as possible. As Figures 28 - 31 。

[0083] There are also 2 blind holes on the hollow triangular column of the sector bottom plate hollow triangular column installation mother plate. The bottom surface of the blind hole is on the same horizontal plane as the sector bottom surface. The purpose of setting the blind holes is also to reduce weight, as Figure 30 , Figure 32 。

[0084] The hollow triangular column of the sector bottom plate hollow triangular column installation mother plate has 3 mounting surfaces in the vertical direction, namely: the first mounting surface, the second mounting surface, and the third mounting surface. The first mounting surface and the second mounting surface are axisymmetric. There are 20 mounting threaded holes arranged in 4 rows and 5 columns with equal horizontal and vertical spacing on the first mounting surface and the second mounting surface at completely symmetric spatial positions. There are 20 mounting threaded holes arranged in 5 rows and 4 columns with equal horizontal and vertical spacing on the third mounting surface. The positions of the threaded holes on the first mounting surface and the threaded holes on the third mounting surface are offset in the vertical direction. Similarly, the positions of the threaded holes on the second mounting surface and the threaded holes on the third mounting surface are offset in the vertical direction. At the same time, the lowermost row of threaded holes on the third mounting surface is located on the sector bottom plate, with the aim of minimizing the mounting height of the center of gravity of the sample to be measured when mounting the sample on the third mounting surface, as Figures 35 - 41 。

[0085] There are 2 symmetric chamfers at the connection position between the sector bottom plate and the top of the hollow triangular column of the sector bottom plate hollow triangular column installation mother plate, as Figures 35 - 41 。

[0086] The second basic component is formed as a frame structure composed of a top beam, a base, a left side wall, and a right side wall, and it can be fixedly installed between 2 of the said columns;

[0094] There are transition fillets between the top beam of the "square-shaped wedge bracket mounting motherboard" and the left side wall and the right side wall, forming a top beam pit, as Figure 48 , [[ID=I12]] Figure 49 .

[0095] The central plane in the vertical direction of the "square" cavity formed between the top beam, the left side wall, the right side wall and the base of the "square-shaped wedge bracket mounting motherboard" coincides with the central plane of the "square-shaped wedge bracket mounting motherboard" in the vertical direction.

[0096] There are 20 threaded holes with equal horizontal and vertical spacing distances on the front surface of the "square-shaped wedge bracket mounting motherboard", as Figure 42 , for the purpose of facilitating the normal fixation of some measured samples with protruding object shape features on the installation plane and their transition tooling.

[0110] The relative positions among the countersunk holes in each set on the "stretching plate 3" are the same as the relative positions among the threaded holes 15 to 17 on the hollow triangular column of the "sector bottom plate hollow triangular column installation mother plate", as shown in Figure 32 、 Figure 69 。

According to the actual usage requirements, at least 5 basic configurations are formed through the relative combination of the basic components and the auxiliary components, and on the premise of ensuring the stiffness of the tooling, the installation requirements of most samples are satisfied as much as possible.

[0114] In addition, it should also be understood that although terms such as "first", "second", etc. may be used herein to describe different elements, parameters, components, regions, layers, and / or parts, these elements, parameters, components, regions, layers, and / or parts should not be limited by these terms. These terms are only used to distinguish one element, parameter, component, region, layer, or part from another element, parameter, component, region, layer, or part. Therefore, without departing from the teachings of the exemplary embodiments of the present invention, the first element, parameter, component, region, layer, or part discussed below may also be referred to as the second element, parameter, component, region, layer, or part. For ease of description, spatial relative terms such as "under", "above", "below", "above", "upper", etc. may be used herein to describe the spatial positional relationship of one element or feature to other elements or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, the element described as "under other elements or features" or "below other elements or features" will then be positioned "above other elements or features" or "over other elements or features". Thus, the exemplary term "under" can include both the orientations of "above" and "under". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding interpretations of the spatial relative descriptors used herein will be made accordingly.

[0145] The terms used herein are for the purpose of describing particular embodiments only and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular forms are also intended to include the plural forms. In addition, it should also be understood that when the terms "comprises" and / or "comprising" are used in this specification, they specify the presence of the stated features, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or combinations thereof.

[0146] Herein, exemplary embodiments according to the present invention are described with reference to schematic cross-sectional views of preferred embodiments (and intermediate structures) that are exemplary embodiments. Thus, variations in the shapes shown, for example, due to manufacturing techniques and / or tolerances are expected. Accordingly, the exemplary embodiments should not be construed as being limited to the specific shapes of the regions shown herein, but may also include, for example, shape deviations resulting from manufacturing.

It will also be understood that terms such as those defined in a general dictionary, unless specifically defined herein, should be construed as having a meaning consistent with their meaning in the context of the relevant art and not to be interpreted in an idealized or overly formal sense.

[0148] The present invention has been described in detail above through specific embodiments and examples, but these do not constitute a limitation to the present invention. Without departing from the principle of the present invention, those skilled in the art can also make many variations and improvements, which should also be regarded as the protection scope of the present invention.
