[0002] In vehicle production process, body -in -white as the reference carrier of whole vehicle assembly, the detection precision of body -in -white full size directly determines the assembly quality, safety and whole vehicle performance of whole vehicle.

[0003] Currently, the size detection of body -in -white is usually three coordinate measurement technology, and the supporting device mainly includes rectangular bottom plate and multiple positioning support frames, the rectangular bottom plate is fixedly arranged on the ground, each support frame is fixedly connected with the bottom plate by fastening bolt, and the height is adjusted by gasket, so that the fixed position and support height of each support frame are adapted to the body -in -white to be measured.

[0004] However, in actual operation process, the position and height of each support frame are often adjusted by operating personnel with the aid of auxiliary tools repeatedly manually, which is not only time-consuming and labor-consuming, and the positioning deviation caused by manual operation is difficult to avoid, seriously affects detection efficiency and accuracy; in addition, when different body -in -white of different models needs to be switched to measure, since the positioning reference points of different body -in -white of different models are different, multiple support frames on the bottom plate need to be frequently disassembled and replaced, which is complicated, and the single replacement disassembly time is long, seriously restricts the efficient operation of production line, and cannot meet the actual needs of modern automobile manufacturing rapid replacement and efficient production. Therefore, a new type of body -in -white measurement support device needs to be developed. UTILITY MODEL CONTENTS

[0005] Therefore, the utility model aims at providing a kind of body -in -white measurement support device, which aims at solving the technical problems that the supporting device matched in the size measurement process of existing body -in -white needs operating personnel to repeatedly manually adjust the position and height of each support frame with the aid of tools in actual operation process, which is time-consuming and labor-consuming, and the positioning deviation caused by manual operation is difficult to avoid, seriously affects detection efficiency and accuracy.

[0006] The utility model aims at providing a kind of body -in -white measurement support device, which aims at solving the technical problems that the supporting device matched in the size measurement process of existing body -in -white needs operating personnel to repeatedly manually adjust the position and height of each support frame with the aid of tools in actual operation process, which is time-consuming and labor-consuming, and the positioning deviation caused by manual operation is difficult to avoid, seriously affects detection efficiency and accuracy.

[0007] The bottom plate is provided with multiple fixed pins, and multiple fixed pins are arranged along the length direction of the bottom plate;

[0008] The support assembly includes a connecting plate, at least two first support frames fixed to one side of the connecting plate, and at least two second support frames fixed to the opposite side of the connecting plate.

The end of the fixing portion away from the guide portion is fixedly connected to the upper surface of the base plate by welding. The circumferential outer edge of the fixing portion is interference-fitted with the wall of the connecting through hole.

[0014] Furthermore, when the fixing pin is inserted into the connecting through hole, the lower surface of the connecting plate is in close contact with the upper surface of the base plate, and the thickness of the connecting plate is one-third to one-half of the total length of the fixing pin.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] Please see Figures 1 to 5 The diagram illustrates a support device for measuring a body-in-white according to this invention. It includes a base plate 11 and a support assembly. The base plate 11 is used to position and place the support assembly. Multiple fixing pins 12 are provided on the base plate 11, spaced apart along the length of the base plate 11. The fixing pins 12 are interference-fitted with the connecting through holes 201 on the connecting plate 21. In this embodiment, the base plate 11 is a rectangular plate structure. Each fixing pin 12 includes a guide portion and a fixing portion integrally connected to the guide portion. The end of the fixing portion away from the guide portion is fixedly connected to the upper surface of the base plate 11 by welding. The circumferential outer edge of the fixing portion is interference-fitted with the wall of the connecting through hole 201. The guide portion guides the entire fixing pin 12 to be quickly and accurately inserted into the connecting through hole 201, reducing alignment time and improving the installation efficiency of the support assembly on the base plate 11. As a specific example, in this embodiment, the fixing portion is a cylindrical structure, and the guide portion is a hemispherical structure. In some embodiments, the base plate may also be the operating table structure integrated into the coordinate measuring machine. It should be understood that the aforementioned coordinate measuring machine is a device well known to those skilled in the art and will not be described in detail here.

[0028] The support assembly is used to position and support the body-in-white. It includes a connecting plate 21, at least two first support frames 22 fixed to one side of the connecting plate 21, and at least two second support frames 23 fixed to the opposite side of the connecting plate 21. The connecting plate 21 has multiple connecting through holes 201. The connecting plate 21 is fixed to the base plate 11 by inserting fixing pins 12 into the connecting through holes 201. In this embodiment, the connecting plate 21 is a rectangular plate structure. A first support frame 22 is provided at each end of one side. The two support frames 22 are symmetrically arranged about the center line in the width direction of the connecting plate. A second support frame 23 is provided at each end of the opposite side. The opening position and number of the connecting through holes 201 on the connecting plate 21 correspond to the design of the fixing pins 12 on the base plate 11.

[0029] Furthermore, the interference fit between the connecting through hole 201 and the fixing pin 12 is 0.15mm-0.3mm. Specifically, in this embodiment, the tolerance range of the total radial length of the fixing pin 12 is (-0.15, 0)mm, the tolerance range of the hole diameter of the connecting through hole 201 is (0, 0.15)mm, and when the fixing pin 12 is inserted into the connecting through hole 201, the lower surface of the connecting plate 21 is in close contact with the upper surface of the base plate 11, and the thickness of the connecting plate 21 is one-third to one-half of the total length of the fixing pin 12. This design can ensure the stability of the connection between the connecting plate 21 and the base plate 11, prevent the support assembly from shaking due to external force collisions or other factors during the measurement of the body-in-white, thus affecting the measurement accuracy, and facilitate the quick removal of the entire support assembly from the base plate 11 when it is necessary to switch the support assembly, which can greatly improve the flexibility and convenience of the device.

[0030] Furthermore, the bottoms of the first support frame 22 and the second support frame 23 are fixedly connected to the upper surface of the connecting plate 21 by bolts. The top of the first support frame 22 is provided with a positioning pin 221, the top of which is a pointed structure. The top of the second support frame 23 is provided with a positioning protrusion 231. The positioning pin 221, the positioning protrusion 231 and the corresponding preset positioning points on the white body are matched to realize the positioning support of the support component on the white body, so as to ensure the position accuracy of the white body during the measurement process and thus improve the accuracy of the measurement results. In some embodiments, a positioning pin structure can also be provided on the top of the second support frame 23 to improve the positioning accuracy of the second support frame for the body-in-white and further ensure the measurement accuracy of the body-in-white. Correspondingly, in practical applications, the positioning pins on the two first support frames 22 are inserted into the positioning holes of the vehicle body's engine compartment to construct a first reference surface to constrain the translational freedom of the body-in-white along the Z-axis and the rotational freedom around the X and Y axes; the positioning pin on one of the second support frames 23 is inserted into the positioning hole of the rear crossbeam of the rear floor of the vehicle body to form a second reference surface to restrict the translational freedom of the body-in-white along the Y-axis and the rotational freedom around the Z-axis; the remaining positioning points (such as the positioning protrusions or positioning pins on the top of the second support frame 23) cooperate with the corresponding points of the body-in-white to form a third reference surface to eliminate the translational freedom along the X-axis. By strictly following the "3-2-1" measurement principle, the six degrees of freedom of the body-in-white in three-dimensional space are effectively constrained, ensuring that the position of the body-in-white is fixed during the measurement process, thereby significantly improving the accuracy and reliability of the measurement results.

[0031] Furthermore, the connecting plate 21 is also provided with a plurality of lifting rings 24. The lifting rings 24 are arranged adjacent to the first support frame 22 or the second support frame 23. The lifting rings 24 are used to connect with the hook of the crane crane to realize the lifting of the support components by the crane crane. In this embodiment, the connecting plate 21 is provided with four lifting rings 24. The four lifting rings 22 are symmetrically arranged about the centerline in the width direction of the connecting plate. Specifically, the lifting rings 24 are semi-circular ring structures, and the two ends of the lifting rings 24 are fixedly connected to the upper surface of the connecting plate 21 by welding.

[0032] In summary, the beneficial effects of the support device for measuring the body-in-white of this utility model are as follows: The first and second support frames in this application are fixed on the connecting plate to form a prefabricated support assembly, realizing modular switching and installation. Furthermore, the interference fit between the fixing pin on the base plate and the connecting through hole on the connecting plate enables rapid positioning and fixing of the entire support assembly on the base plate. Compared to the prior art where operators need to repeatedly manually adjust the position of the support frame on the base plate using auxiliary tools, this significantly reduces installation time. Simultaneously, the lifting ring facilitates the rapid lifting of the support assembly using a crane, further improving the installation and disassembly efficiency of the entire support device, effectively shortening the preparation time for body-in-white measurement, and increasing overall operational efficiency. In practical application, only the support assembly with different layouts of the first and second support frames needs to be replaced to quickly adapt to the positioning requirements of different body-in-white models, eliminating the need for extensive disassembly and replacement of the support frames. This effectively reduces the disassembly and assembly time for single model changes, meeting the actual needs of rapid model changes and efficient production in modern automobile manufacturing, and improving the operating efficiency of the production line.
