[0026] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0027] like Figures 1 to 3 A detection tool is shown, the front part of the detection tool is provided with a positioning surface 5 and a positioning pin 6, the positioning pin 6 is used to cooperate with the instrument panel positioning hole on the vehicle body, and the positioning surface 5 is used to fit with the reference surface on the vehicle body; the rear part of the detection tool is provided with a first observation hole 8 and a second observation hole 9, the first observation hole 8 is provided with a first scale 10 for measuring the position of the door positioning hole on the front door of the vehicle in the front and rear direction, and the second observation hole 9 is provided with a second scale 11 for measuring the position of the door positioning hole on the front door of the vehicle in the up and down direction. The instrument panel positioning hole is a positioning hole on the vehicle body for positioning the instrument panel, the reference surface is a plane on the vehicle body, and the door positioning hole is a positioning hole on the front door of the vehicle.

[0028] When the above-mentioned detection tool is used, the positioning surface 5 and the positioning pin 6 are associated with the instrument panel positioning hole on the vehicle body, and then associated with the position of the instrument panel. The first observation hole 8 and the first scale 10 can be used to read the position of the door positioning hole on the front door of the vehicle in the front and rear directions, and the second observation hole 9 and the second scale 11 can be used to read the position of the door positioning hole on the front door of the vehicle in the up and down directions. The installation position of the front door interior panel is determined by the position of the door positioning hole on the front door of the vehicle. In other words, the relative position of the instrument panel and the front door interior panel can be detected by the detection tool, and then it can be determined whether the matching quality between the instrument panel and the front door interior panel meets the requirements.

[0029] By adopting the above technical solution and the above detection tooling, the relative positions of the instrument panel and the front door interior panel on the vehicle body can be indirectly detected before the instrument panel and the front door interior panel are assembled. Then, it can be determined whether there is a problem with the matching quality between the instrument panel and the front door interior panel, and the matching quality between the instrument panel and the front door interior panel can be detected earlier, more intuitively and more accurately. The difficulty of detecting, analyzing and adjusting the matching quality between the instrument panel and the front door interior panel is reduced.

[0030] In some embodiments, in order to facilitate the arrangement and reading of scales, the first observation hole 8 is a strip-shaped hole whose length extends in the front-to-back direction, and the second observation hole 9 is a strip-shaped hole whose length extends in the up-down direction.

[0031] In some embodiments, the front part of the inspection tool is provided with a plurality of support columns 4 for supporting on the vehicle body, and the end faces of the plurality of support columns 4 constitute positioning surfaces 5. The above technical solution is adopted, and the support columns 4 are used to support on the vehicle body, which facilitates the cooperation between the positioning pins 6 and the instrument panel positioning holes on the instrument panel positioning parts. As a specific example, four support columns 4 are provided at the front part of the inspection tool.

[0032] In some embodiments, the ends of the plurality of support columns 4 are provided with magnetic attraction portions for magnetic attraction on the vehicle body. By adopting the above technical solution, the magnetic attraction portions can be provided to magnetically attract the plurality of support columns 4 on the vehicle body, which provides convenience for the use of the inspection tool. As a specific example, the support column 4 includes a support column body and a magnet block fixedly connected to the end of the support column body, and the magnet block constitutes the above magnetic attraction portion.

[0033] In some embodiments, two first observation holes 8 are provided at the rear of the detection tool, and the two first observation holes 8 are arranged at intervals in the front-to-back direction, and the two first observation holes 8 are used to observe the front edge and the rear edge of the door positioning hole on the front door of the vehicle, respectively. With the above technical solution, the two first observation holes 8 can better detect the position of the door positioning hole on the front door of the vehicle in the front-to-back direction.

[0034] In some embodiments, two second observation holes 9 are provided at the rear of the detection tooling, and the two second observation holes 9 are arranged at intervals in the up-down direction, and the two second observation holes 9 are used to observe the upper edge and the lower edge of the door positioning hole on the front door of the vehicle, respectively. With the above technical solution, the two second observation holes 9 can better detect the position of the door positioning hole on the front door of the vehicle in the up-down direction.

[0035] As a preferred example, two first observation holes 8 are provided at the rear of the detection tooling, and two second observation holes 9 are provided at the rear of the detection tooling, and the two first observation holes 8 and the two second observation holes 9 are distributed in a "cross" shape. The four observation holes distributed in a "cross" shape can better detect the position of the door positioning hole on the front door of the vehicle.

[0036] In some embodiments, the first observation hole 8 and the second observation hole 9 are spaced apart from each other. By adopting the above technical solution, the structural strength of the rear part of the detection tool can be ensured, the possibility of deformation at the first observation hole 8 and the second observation hole 9 can be reduced, and the detection accuracy of the detection tool can be ensured. As a preferred example, the two first observation holes 8, the two second observation holes 9, and the first observation hole 8 and the second observation hole are all spaced apart from each other.

[0037] In some embodiments, the detection tooling further includes a substrate portion 1, a connecting plate portion 2 extending outward from the rear edge of the substrate portion 1, and a detection plate portion 3 extending backward from the outer edge of the connecting plate portion 2, a positioning pin 6 is fixedly connected to the substrate portion 1, and a first observation hole 8 and a second observation hole 9 are both provided on the detection plate portion 3. In a specific implementation, the substrate portion 1, the connecting plate portion 2, and the detection plate portion 3 can be formed by bending a single plate, and the positioning pin 6 can be fixedly connected to the substrate portion 1 by welding. The above technical solution has the characteristics of simple structure and easy implementation.

[0038] In some embodiments, the detection plate portion 3 is provided with a detection portion 7 protruding outward, and the first observation hole 8 and the second observation hole 9 are both provided on the detection portion 7. With the above technical solution, the detection portion 7 protruding outward can reduce the contact area between the detection plate portion 3 and the front door of the vehicle, which helps to reduce the difficulty of matching the detection tooling with the front door of the vehicle. As a specific example, in order to improve the structural strength of the detection portion 7, the detection portion 7 is provided as a convex rib-shaped structure protruding outward.

[0039] In some embodiments, the substrate portion 1 is provided with weight-reducing holes 12 . Providing the weight-reducing holes 12 can reduce the weight of the detection tooling and can reduce the difficulty of using the detection tooling.

[0040] In some embodiments, two positioning pins 6 are provided at the front of the detection tool, one positioning pin 6 is a round pin, and the other positioning pin 6 is a diamond pin. The round pin is the main positioning pin, which is used to limit two degrees of freedom; the diamond pin is the secondary positioning pin, which is used to limit one degree of freedom. The positioning is performed by combining the round pin and the diamond pin, which has the characteristic of facilitating the installation of the detection tool on the vehicle body. Obviously, in other embodiments, multiple positioning pins 6 may be provided at the front of the detection tool.

[0041] In some embodiments, the first scale 10 includes a plurality of scale lines arranged in sequence and at intervals along the length direction of the first observation hole 8, and the second scale 11 includes a plurality of scale lines arranged in sequence and at intervals along the length direction of the second observation hole 9. In a specific implementation, the spacing between two adjacent scale lines in the first scale 10 can be set to 1 mm, and the spacing between two adjacent scale lines in the second scale 11 can be set to 1 mm.

[0042] like Figure 4 and Figure 5 As shown, the detection process of the above-mentioned detection tool is as follows: the multiple positioning pins 6 of the detection tool are respectively inserted into the multiple instrument panel positioning holes on the vehicle body 13, and the positioning surface 5 is fitted with the reference surface on the vehicle body 13 to associate the position of the instrument panel on the vehicle body 13. The front door is naturally closed, and the position of the door positioning hole on the front door 14 is observed through the first observation hole 8 and the second observation hole 9, that is, the position of the front door interior panel is associated, and the first scale 10 and the second scale 11 are used to read, so that the deviation of the door positioning hole in the front and rear direction and the up and down direction can be detected, and this deviation is the relative position deviation between the instrument panel and the front door interior panel.

[0043] The above-mentioned inspection tooling can be used in a welding workshop of an automobile to inspect the vehicle body 13, cross the dimension chain of the instrument panel and the front door interior panel at the vehicle body end, and detect the relative positions of the instrument panel and the front door interior panel on the vehicle body 13, which helps to prevent the problem of unqualified matching quality between the instrument panel and the front door interior panel in advance.
