Description

Technical Field

[0001] The invention relates to the technical field of vehicle body manufacturing, and in particular to a device, application and method for measuring the verticality of a component. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] A skirt panel is provided inside the bogie under the vehicle side beam to provide better protection for the removal of equipment and aerodynamic performance for the vehicle. The skirt panel is not a whole piece, but multiple pieces. The skirt panel is installed through a skirt panel mounting seat, which is welded to the lower plane of the chassis side beam. During the welding process, the skirt panel mounting seat produces thermal deformation, which affects the verticality of the skirt panel mounting seat relative to the lower plane of the side beam. In addition, there are more than 30 skirt panel mounting seats in total on the lower plane of the two side beams on each chassis. The 32 skirt panel mounting seats of a single vehicle are installed in different processes. Most of the skirt panel mounting seat beams are pre-assembled on the side beams in advance during the side beam parts process. The side beam pre-assembly is also divided into two construction sites, some models are installed at the manufacturer, and some models are constructed in the factory. For the skirt plate mounting seats that cannot be pre-assembled in advance (they compete with the side beam welding tooling during pre-assembly), they are installed after the base frame is welded and before the base frame is handed over. Because multiple processes are involved, the verticality measurement standards of the skirt plate mounting seats are not unified, which ultimately causes the overall flatness of the skirt plate mounting seats on the side beam to be out of tolerance, with a value between 2.5 and 4.5 mm.

[0004] Considering the appearance of the vehicle, after all skirt panels are installed, the overall flatness requirement is that the outer surface of the skirt panel mounting seat is ≤2mm / 3m, and the verticality of a single skirt panel mounting seat and the lower plane of the side beam is ≤0.5mm. That is to say, when the skirt panel is installed during the manufacturing process of the vehicle body, due to the excessive verticality between the skirt panel mounting seat and the lower plane of the side beam of the vehicle body chassis, the problem of the skirt panel being unable to be installed occurs, or the flatness of multiple skirt panels after installation cannot be effectively guaranteed. Therefore, it is necessary to detect the verticality of the skirt panel mounting seat relative to the lower plane of the side beam of the vehicle body chassis. The inventor found that the following problems exist in the actual detection process:

[0005] refer to Figure 1 As shown, the lower plane of the vehicle body chassis side beam is actually only about 5 cm wide and has a flange structure. The bottom plate of the skirt panel mounting seat also has a set width. After the skirt panel mounting seat is welded to the three sides of the side beam, the distance between the bottom plate of the skirt panel mounting seat and the flange of the chassis side beam is small, only about 1-2 mm. After welding, the lower plane of the chassis side beam facing the vertical surface of the skirt panel mounting seat is almost completely covered by the weld, and the space between the skirt panel mounting seat and the flange of the side beam cannot be used. The verticality of the vertical surface relative to the side beam is measured using a right-angle measuring ruler 5.

[0006] In actual construction, even if only the verticality of the skirt mounting base itself is measured, Figure 2 As shown, since a transition section is provided between the vertical surface and the plane of the skirt plate mounting seat, and the transition section is a rounded corner, it is also impossible to use a right-angle measuring ruler to directly measure, and the rounded corner position cannot be placed with a right-angle measuring ruler at all;

[0007] refer to Figure 4 As shown, when the missing corner measuring tool 6 is used for verticality detection, the tool needs to be measured because of the gap; Chinese patent application CN201621441666.1 discloses a welded tube sheet verticality measuring tool, which uses straight plates on both sides to measure the verticality of the welded tube sheet by changing the angles of the straight plates on both sides. The overall occupied area is large and is not suitable for skirt plate mounting seats with smaller spaces; in addition, it is equivalent to missing a corner. In order to ensure accuracy, it needs to be measured, and the measurement method is relatively complicated. After multiple uses, it needs to be re-measured to ensure the accuracy of the measurement results, and multiple skirt plate mounting seats cannot be quickly detected.

[0008] Another method is to make a template 7, refer to Figure 5 As shown, it is similar to the shape of a right-angle measuring ruler, and an arc transition is set at the right angle position to avoid the transition section of the skirt plate mounting seat. An opening 7-1 is opened at the position of the side beam flange, so that it is stuck on the side beam flange, and then the gap is measured with a feeler gauge to confirm the verticality size. This solution is stuck on the side beam flange, because its reference is not the lower plane of the side beam, but the side beam flange, but the side beam flange has an arc, which has a large error.

[0009] In summary, not only for the skirt panel mounting seat, but also for other measured components in a complex environment, that is, the measured component whose verticality needs to be measured is supported by a fixed component, because the width of the fixed component is relatively narrow, and the measured component and the fixed component are welded together, and the fixed component is provided with a weld on the side of the measured component, that is, it is uneven. Because of this unevenness, it is impossible to place a measuring ruler, and the accuracy of the verticality detection of the measured component cannot be guaranteed; the measured component has a bottom plate and a vertical panel. Because there is a transition section between the bottom plate and the vertical panel, a right-angle measuring ruler cannot be directly set for measurement. The device with missing corners needs to be measured multiple times, which affects the speed and efficiency of the detection. If it is not measured, it affects the accuracy of the detection; in addition, for the measured components that are out of tolerance, such as the skirt panel mounting seat, they can only be replaced in the end to meet the size requirements. Replacement requires cutting off the existing skirt panel mounting seat and replenishing the material, which has a great impact on the production rhythm and is not conducive to ensuring product quality. Summary of the invention

[0010] In view of the shortcomings of the prior art, the first object of the present invention is to provide a device for measuring the verticality of a component, which can measure the verticality of a component under test in a complex environment, not only ensuring the measurement accuracy, but also effectively improving the measurement efficiency.

[0011] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0012] A device for measuring the verticality of a component comprises a support seat, a right-angle measuring ruler and a feeler gauge, the support seat is a door-shaped support seat, the two sides of the support seat are supported by fixed components of the component to be measured, the top surface of the support seat is a plane, the top surface of the support seat and the fixed components of the component to be measured are parallel to each other, the support seat can be arranged across the bottom plate of the component to be measured and the weld on the side of the bottom plate, the inner side surface of the support seat is in contact with the vertical panel of the component to be measured or the inner side surface of the support seat is set at a distance from the vertical panel, the top surface of the support seat is arranged lower than the top surface of the component to be measured, the right-angle measuring ruler can be placed on the top surface of the support seat, the first right-angle side of the right-angle measuring ruler is in contact with the top surface of the support seat, the feeler gauge is inserted between the second right-angle side and the vertical panel of the component to be measured, and the verticality of the component to be measured relative to the fixed component is obtained by obtaining the distance between the second right-angle side and the vertical panel of the component to be measured at different heights by the feeler gauge.

[0013] As described above, for a device for measuring the verticality of a component, considering that the top surface of the support seat is the measuring surface of the right-angle measuring ruler, in order to ensure the measurement accuracy, the top surface of the support seat cannot be set too high, and should be as low as possible, but cannot touch the transition section of the component to be measured. The height of the support seat is 2mm-5mm higher than the sum of the height of the bottom plate of the component to be measured and the height of the transition section of the component to be measured, and the transition section of the component to be measured is located between the bottom plate and the vertical panel of the component to be measured.

[0014] A device for measuring the verticality of a component as described above, wherein the support seat comprises two columns, the bottom surfaces of the columns are planes, the parallelism between the bottom surfaces of the columns and the top surface of the support seat is ≤0.1 mm, the top plate is supported by the columns on both sides, the top plate is provided with the top surface, and the thickness of the top plate is greater than the height of the transition section between the vertical plate and the bottom plate of the component to be measured;

[0015] The length of the column is greater than or equal to 15mm and less than or equal to 25mm to ensure the contact area between the support seat and the fixed component, ensure the stability of the support seat structure, facilitate the operation of the staff, and effectively control the processing cost.

[0016] In the device for measuring the verticality of a component as described above, an inclined section is arranged between the inner side surface of the top plate close to the vertical panel of the component to be measured to avoid the transition section between the vertical panel and the bottom plate of the component to be measured, so that the thickness of the top plate on one side close to the vertical panel is smaller than the thickness on the other side, and the arrangement of the inclined section makes the width of the inner side surface of the top plate smaller than the width of the top surface.

[0017] In a device for measuring the verticality of a component as described above, the width of the inclined section is greater than or equal to the width of the transition section, the height of the inclined section is greater than or equal to the height of the transition section, the width of the inclined section is 0-2mm wider than the width of the transition section, and the height of the inclined section is 0-0.5mm higher than the height of the transition section, so as to avoid contact between the support seat and the transition section, which is conducive to controlling the height of the support seat.

[0018] In the device for measuring the verticality of a component as described above, the thickness of the top plate is 1mm-3mm higher than the height of the thinner side of the inclined surface section.

[0019] In the device for measuring the verticality of a component as described above, because the fixed component of the component to be measured is slender, combined with the situation of the component to be measured, the support seat is limited to be slender as well. In order to ensure the stability of the support seat, the width of the support seat must be ensured. The width of the support seat is smaller than the difference between the distance between the vertical panel of the component to be measured and the flange of the fixed component and the transition section of the component to be measured, so as to avoid the transition section of the component to be measured.

[0020] In a device for measuring the verticality of a component as described above, a groove is provided on the side of the support seat away from the top surface, the height of the groove is greater than the bottom plate setting of the measured component, and the length of the groove is greater than the sum of the length of the bottom plate and the width of the weld on the side of the bottom plate, so that the groove avoids the weld setting of the bottom plate and its side.

[0021] In the device for measuring the verticality of a component as described above, in order to prevent the inner side surface of the support seat from being in contact with the bottom plate of the component to be measured, the height of the groove is 2 mm to 4 mm higher than the bottom plate of the component to be measured;

[0022] Taking into account the width of the weld, the length of the groove is 6 cm-10 cm longer than the length of the base plate.

[0023] In the second aspect, the present invention discloses an application of a device for measuring the verticality of a component, which is applied to the verticality detection during or after the installation of a vehicle body skirt mounting seat. Since the support seat and the fixed component such as the lower surface of the chassis side beam are parallel to each other, the verticality of the vehicle body skirt mounting seat relative to the lower surface of the chassis side beam can be measured by measuring the verticality between the vertical panel and the support seat.

[0024] In a third aspect, the present invention discloses a component verticality measurement method, which uses the component verticality measurement device, and includes the following contents:

[0025] The support seat is arranged across the bottom plate of the measured component, so that the fixed component of the measured component supports the support seat, the support seat is arranged to avoid the weld seam on the peripheral side of the bottom plate of the measured component, and the inner side surface of the support seat contacts the vertical panel of the measured component or the inner side surface of the support seat is arranged to be spaced apart from the vertical panel;

[0026] Place a right-angle measuring ruler on the top surface of the support base, with the first right-angle side of the right-angle measuring ruler in contact with the top surface of the support base, and the second right-angle side of the right-angle measuring ruler close to the vertical panel of the measured component;

[0027] Insert the feeler gauge between the second right-angled side and the vertical panel of the measured component. At different heights of the vertical panel, the distance between the second right-angled side and the vertical panel at different heights is obtained by the feeler gauge, thereby obtaining the verticality of the measured component at different heights relative to the support seat or fixed component.

[0028] The beneficial effects of the present invention are as follows:

[0029] 1) A support seat is provided in the present invention. The support seat is a door-type support seat, which can be effectively arranged across the bottom plate of the measured component and can be placed on the side of the vertical panel of the measured component, fit with the vertical panel of the measured component or set at a distance between the two. The top surface of the support seat is a plane and is parallel to the fixed component, so that the top surface of the support seat forms a measurement reference surface. The first right-angle side of the right-angle measuring ruler is placed on the top surface of the support seat, and a feeler gauge can be inserted between the second right-angle side and the vertical panel of the measured component. The verticality of the measured component relative to the support seat, that is, the fixed component, can be obtained by obtaining the distance between the second right-angle side and the vertical panel of the measured component at different heights with the feeler gauge. As above, the entire measuring device provides a relatively flat reference surface through the support seat. Because the right-angle measuring ruler and the feeler gauge are used, both of which are standard parts, measurement can be performed without testing several, thereby ensuring measurement accuracy; and the speed and efficiency of measurement can be ensured.

[0030] 2) In the present invention, the height of the support seat is limited so that the height of the support seat is higher than the bottom plate and transition section of the component to be measured to avoid contact with the bottom plate and ensure the flatness of the top surface of the support seat. However, it cannot be too high because the higher the height of the support seat, the closer it is to the top surface of the component to be measured, and the measurement results at different positions may be closer, affecting the accuracy of the detection results.

[0031] 3) In the present invention, the support seat supports the top plate through the columns, and the height of the top plate is the height of the support seat. Considering that the top plate needs to avoid the transition section of the measured component, the thickness of the top plate is greater than the height of the transition section, and the length of the columns is limited. The limitation of the width of the support seat effectively ensures the stability of the slender support seat. And an inclined section is set on the side of the inner side of the top plate close to the vertical panel of the measured component. By limiting the height and width of the inclined panel, the height of the top plate is further reduced, but it will not affect the setting strength of the top plate, and the top plate can fully avoid the transition section of the measured component.

[0032] 4) In the present invention, a groove is provided on the support seat, and the length of the groove is limited so that the support seat is set across the bottom plate and the side weld of the measured component. By limiting the height of the groove, the overall height of the support seat is effectively controlled while ensuring the stability of the overall structural setting.

[0033] 5) The measuring device of the present invention can be applied to the verticality detection of the skirt panel mounting seat during or after the installation of the vehicle body. The verticality detection is performed on all the skirt panel mounting seats of a single vehicle, which not only ensures the accuracy and precision of the measurement, but also ensures the efficiency of the measurement. After the verticality of a single skirt panel mounting seat is ensured, the flatness of all skirt panels after being installed through the skirt panel mounting seat can be guaranteed.

[0034] 6) The measurement method provided in the present invention can quickly measure the verticality of the vertical panel of a single measured component relative to the top surface of the support seat. The measurement steps are simple, convenient for staff to operate, and can ensure the accuracy of the measurement results. Because the support seat and the fixed component such as the lower surface of the chassis side beam are parallel to each other, the verticality of the body skirt mounting seat relative to the lower surface of the chassis side beam can be quickly measured.

[0046] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0047] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless otherwise explicitly stated in the present invention, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof;

[0048] As introduced in the background technology, the existing technology has the problems of low accuracy and low efficiency in component verticality detection under complex environment. In order to solve the above technical problems, the present invention proposes a device for measuring component verticality.

[0049] Embodiment 1

[0050] In a typical embodiment of the present invention, reference is made to Figure 6As shown, a device for measuring the verticality of a component comprises a support seat 3, a right-angle measuring ruler 5 and a feeler gauge. The support seat 3 is a door-shaped, and both sides of the support seat 3 are supported by the fixed components 2 of the measured component 1. The top surface of the support seat 3 is a plane, and the top surface of the support seat 3 is parallel to the fixed components 2 of the measured component 1. The support seat 3 can be arranged across the bottom plate 1-1 of the measured component and the weld 4 on the side of the bottom plate 1-1. The inner side surface of the support seat 3 contacts the vertical panel 1-2 of the measured component or the inner side surface of the support seat 3 is arranged at a distance from the vertical panel 1-2. The top surface of the support seat 3 is arranged lower than the top surface of the measured component. The right-angle measuring ruler 5 can be placed on the top surface of the support seat 3. The first right-angle side of the right-angle measuring ruler 5 contacts the top surface of the support seat 3, and the feeler gauge is inserted between the second right-angle side and the vertical panel 1-2 of the measured component. The distance between the second right-angle side and the vertical panel 1-2 of the measured component is obtained by the feeler gauge at different heights to obtain the verticality of the measured component 1 relative to the support seat 3, that is, the fixed component 2.

[0051] In this embodiment, the support seat 3 includes two columns 3-1, the height of the column 3-1 is the height of the support seat, the transverse cross-section of the column 3-1 can be a rectangle, the bottom surface of the column 3-1 is a plane, the parallelism between the bottom surface A of the column and the top surface of the support seat 3 is ≤0.1mm, and a smaller flatness requirement can further reduce the error, and the top plate 3-2 is supported by the columns 3-1 on both sides. The top plate 3-2 is a flat plate, and the top plate 3-2 has a top surface. The thickness of the top plate 3-2 is greater than the height of the transition section 1-3 between the vertical panel 1-2 and the bottom plate 1-1 of the measured component; during processing, the column 3-1 and the top plate 3-2 are processed into an integrated structure through an aluminum plate; of course, in some examples, in order to facilitate processing, the column 3-1 and the top plate 3-2 can also be made into a split structure, but the split structure needs to be fixedly connected by fasteners such as bolts when in use, and the top plate and the column are connected from the side of the column.

[0052] Considering that the top surface of the support seat 3 is the measuring surface of the right-angle measuring ruler 5, in order to ensure the measurement accuracy, the top surface of the support seat 3 cannot be set too high, and should be as low as possible, but cannot touch the transition section 1-3 of the measured component. The height E of the support seat is 2mm-5mm higher than the sum of the height of the bottom plate 1-1 of the measured component and the height of the transition section 1-3 of the measured component. The transition section 1-3 of the measured component is located between the bottom plate 1-1 and the vertical panel 1-2 of the measured component.

[0053] It is easy to understand that the sizes of the columns 3-1 on both sides are the same, the length B of the column is consistent with the length of the support base 3, the length B of the column 3-1 is greater than or equal to 15mm and less than or equal to 25mm, such as 20mm, to ensure the contact area between the support base 3 and the fixed component 2, to ensure the stability of the support base 3 structure, to facilitate the operation of the staff, a too heavy support base 3 is not conducive to the staff's handling, and to effectively control the processing cost.

[0054] Considering that the top surface of the support seat 3 is the measuring surface of the right-angle measuring ruler 5, in order to ensure the measurement accuracy, the top surface of the support seat 3 cannot be set too high, and should be as low as possible, but cannot touch the transition section 1-3 of the measured component. The height of the support seat 3, that is, the height of the top plate 3-2, is 2mm-5mm higher than the sum of the height of the bottom plate 1-1 of the measured component and the height of the transition section 1-3 of the measured component. The transition section 1-3 of the measured component is located between the bottom plate 1-1 of the measured component 1 and the vertical panel 1-2.

[0055] It should be noted that in order to reduce the height of the top plate 3-2 as much as possible, Figure 6 and Figure 7 As shown, an inclined surface section 3-4 is arranged between the inner side surface of the top plate 3-2 and the vertical panel 1-2 of the component to be measured to avoid the transition section 1-3 between the vertical panel 1-2 and the bottom plate 1-1 of the component to be measured, so that the thickness of the top plate 3-2 on one side close to the vertical panel 1-2 is smaller than the thickness on the other side. The arrangement of the inclined surface section 3-4 makes the width of the inner side surface of the top plate 3-2 smaller than the width of the top surface. In this way, the arrangement of the inclined surface section 3-4 allows the inner side surface of the top plate 3-2 to avoid the transition section 1-3, so that the height of the inner side surface of the top plate 3-2 does not need to be too high, and does not have to be above the transition section 1-3, and the detection device is controlled not to be too high, providing a larger measurement space for the right-angle measuring ruler 5 and the feeler gauge, which not only avoids the waste of materials, but also helps to ensure the accuracy of the detection results.

[0056] It is easy to understand that the width of the bevel section 3-4 is greater than or equal to the width of the transition section 1-3, the height of the bevel section 3-4 is greater than or equal to the height of the transition section 1-3, the width of the bevel section 3-4 is 0-2mm wider than the width of the transition section 1-3, and the height H of the bevel section is 0-0.5mm higher than the height of the transition section 1-3 to avoid contact between the support seat 3 and the transition section 1-3, which is beneficial to control the height of the support seat 3; in some examples, the width of the bevel section 3-4 is the same as the height H of the bevel section, so that the inclination angle of the bevel section 1-3 relative to the top surface is 45°, and the height H of the bevel section is the same as the radius of the transition section.

[0057] In addition, because the fixed component 2 of the measured component 1 is slender, the support seat 3 is also restricted to be slender. In order to ensure the stability of the support seat 3, the width F of the support seat must be ensured. The width F of the support seat 3 is smaller than the difference between the distance between the vertical panel 1-2 of the measured component and the flange of the fixed component 2 and the transition section 1-3 of the measured component, so as to avoid the transition section 1-3 of the measured component while ensuring the setting strength of the support seat 3.

[0058] It is easy to understand that a groove 3-3 is provided on the side of the support seat 3 away from the top surface, the height G of the groove is higher than the bottom plate 1-1 of the measured component, and the length of the groove 3-3 is greater than the sum of the length of the bottom plate 1-1 and the width of the weld 4 on the side of the bottom plate 1-1, so that the groove 3-3 avoids the bottom plate 1-1 and the weld 4 on its side.

[0059] In order to prevent the inner side of the support seat 3 from fitting with the bottom plate 1-1 of the component to be measured, the height G of the groove is 2mm-4mm higher than the bottom plate 1-1 of the component to be measured, which is convenient for processing and manufacturing;

[0060] Taking into account the width of the weld 4, the length C of the groove is 6cm-10cm longer than the length of the base plate 1-1, and specifically 5cm can be selected. The distance between the groove 3-3 and one side of the base plate 1-1 is 2.5cm, which effectively avoids the influence area of ​​the weld 4 without making the support seat 3 too long. By limiting the length of the groove 3-3, the length of the support seat, that is, the length of the top plate, is limited, and the length D of the support seat is limited, that is, the sum of the length of the groove 3-3 and the length of the columns on both sides.

[0061] Among them, the thickness of the top plate 3-2 is 1mm-3mm higher than the height of the thinner side of the inclined surface section 3-4. In some examples, the overall thickness of the top plate can be 7mm, the height of the groove is also 7mm, and when the radius of the transition section is 5mm, the height of the inclined surface section can be 5mm, and the width of the inclined surface section is also 5mm.

[0062] It should be noted that the right-angle measuring ruler is an existing right-angle measuring ruler, and the feeler gauge is an existing pair of feeler gauges (such as a thickness gauge), and both are standard parts.

[0063] In addition, it is easy to understand that the application of a component verticality measuring device is applied to the verticality detection during or after the installation of the vehicle body skirt mounting seat.

[0064] The above-mentioned measuring device can be used to measure the verticality of the skirt board mounting seat. The measurement of the verticality of the skirt board mounting seat is simple and convenient, and can be unified in different processes. The support seat in the measuring device does not participate in the measurement, and the right-angle measuring ruler 5 can easily measure the verticality of the skirt board mounting degree and the lower plane of the side beam. The measuring device can change the length of the measuring device according to the different sizes of the skirt board mounting seats, which overcomes the problem that the verticality of the skirt board mounting seat and the lower plane of the side beam cannot be measured. The measuring device is used for installation in different processes. The verticality of the skirt board mounting seat is guaranteed at this process. When the chassis is finally delivered, the verticality of a single skirt board mounting seat among more than 30 skirt board mounting seats meets the requirements, and the overall flatness can also meet the requirements, so there is no need to adjust or even replace the skirt board mounting seat, saving 2 hours / unit of the body adjustment time of the skirt board mounting seat and 1 hour / unit of the skirt board adjustment in the general assembly plant.

[0065] Embodiment 2

[0066] The difference between this embodiment and the first embodiment is that:

[0067] The inner side of the top plate close to the vertical panel of the measured component is not provided with an inclined section, so it is necessary to raise the height of the support seat groove to avoid interference between the top plate and the transition section of the measured frame.

[0068] Embodiment 3

[0069] This embodiment discloses a component verticality measurement method, which uses a component verticality measurement device described in the first embodiment or the second embodiment, and includes the following contents:

[0070] The support seat 3 is arranged across the bottom plate 1-1 of the measured component, so that the fixed component 2 of the measured component 1 supports the support seat 3, the support seat 3 is arranged to avoid the weld 4 on the peripheral side of the bottom plate 1-1 of the measured component 1, and the inner side surface of the support seat 3 contacts the vertical panel 1-2 of the measured component or the inner side surface of the support seat 3 is arranged at a distance from the vertical panel 1-2;

[0071] Place the right-angle measuring ruler 5 on the top surface of the support seat 3, with the first right-angle side of the right-angle measuring ruler 5 in contact with the top surface of the support seat 3, and the second right-angle side of the right-angle measuring ruler 5 close to the vertical panel 1-2 of the measured component;

[0072] Insert the feeler gauge between the second right-angled side and the vertical panel 1-2 of the component to be measured. At different heights of the vertical panel 1-2, the feeler gauge is used to obtain the distance between the second right-angled side and the vertical panel 1-2 at different heights (including at least three places, the bottom side, the middle side and the top side of the vertical panel). In this way, the verticality of the component to be measured at different heights relative to the support seat or the fixed component is obtained, and compared with the verticality requirement. If the verticality requirement is exceeded, the component to be measured needs to be adjusted.

[0073] In this way, in the case where multiple measured components need to be measured, the measuring device is used to assist in installation and measurement in each installation process. The measuring device is used to check the verticality before installation. After welding the skirt board mounting seat, the right-angle measuring ruler and feeler gauge in the measuring device are used to measure the verticality, thereby achieving unified measurement standards and unified installation methods. The overall flatness of the 32 skirt boards on the chassis side beams after installation will no longer exceed the tolerance, reducing the rework time and effectively improving the production efficiency.

[0074] When in use, the square ruler can be placed at multiple positions such as the middle or side of the vertical panel of the measured component to accurately determine the verticality of the vertical panel of the measured component relative to the fixed component from multiple positions.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
