Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and particularly relates to a detection tool for the surface difference and gap of a vehicle door. Background Art

[0002] At present, during the installation process of a vehicle door, deviations are likely to occur. For example, the surface difference or gap between the vehicle door frame and the side wall outer panel is too large, resulting in problems such as poor appearance quality of the vehicle door, abnormal noise when opening and closing, and even collision with surrounding components. To ensure the installation accuracy of the vehicle door, during the installation process of the vehicle door, surface difference detection and gap detection are usually carried out on the vehicle door. In the related art, the surface difference detection and gap detection of the vehicle door are carried out separately. For example, first, the surface difference between the vehicle door and related components is detected, and the position of the vehicle door is adjusted based on the surface difference detection result. Then, the gap between the vehicle door and related components is detected, and the position of the vehicle door is adjusted based on the gap detection result. On the one hand, the separate implementation of surface difference detection and gap detection will lead to low detection efficiency during the installation process of the vehicle door, and ultimately result in low installation efficiency of the vehicle door. On the other hand, when adjusting the installation position of the vehicle door based on the gap detection result, it is inevitable to affect the surface difference between the vehicle door and related components. Correspondingly, when adjusting the installation position of the vehicle door based on the surface difference detection result, it is inevitable to affect the gap between the vehicle door and related components, resulting in the surface difference or gap between the vehicle door and related components still possibly not meeting the installation requirements, and ultimately resulting in low installation accuracy of the vehicle door. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems in the related art to some extent.

[0004] To this end, the present invention provides a detection tool for the surface difference and gap of a vehicle door to improve the installation efficiency and installation accuracy of the vehicle door.

[0005] The detection tool for the surface difference and gap of the vehicle door of the present invention includes a tool body and a first protrusion. The tool body is provided with a first mark and a fitting portion for fitting with the side wall outer panel. The first mark and the fitting portion are arranged at intervals along a first direction. The maximum distance between the first mark and the fitting portion in a second direction is equal to the minimum value of the surface difference between the side wall outer panel and the vehicle door. The first protrusion is arranged between the fitting portion and the first mark in the first direction. The first protrusion protrudes from the tool body in the second direction and is connected to the tool body. The minimum distance between the surface of the first protrusion away from the fitting portion in the first direction and the fitting portion in the first direction is equal to the minimum value of the gap between the side wall outer panel and the vehicle door. Wherein, the second direction is perpendicular to the first direction.

[0006] Optionally, the door surface difference and gap detection tooling further includes a second protrusion. The first protrusion protrudes from the tooling body in the second direction and is connected to the tooling body. The first mark is disposed between the first protrusion and the second protrusion in the first direction. The second protrusion has a second mark, and the maximum distance between the second mark and the fitting portion in the second direction is equal to the maximum value of the surface difference between the outer side panel and the door.

[0007] Optionally, the second mark is formed on the end face of the second protrusion away from the tooling body in the second direction; and / or, the tooling body includes a first end face and a second end face oppositely arranged in the second direction. The second end face is closer to the first protrusion than the first end face, and the portion of the second end face disposed between the first protrusion and the second protrusion forms the first mark.

[0008] Optionally, the door surface difference and gap detection tooling further includes a third protrusion. The third protrusion protrudes from the tooling body in the second direction and is connected to the tooling body. The first mark is disposed between the first protrusion and the third protrusion in the first direction. The maximum distance between the surface of the third protrusion facing the first protrusion and the surface of the first protrusion facing away from the second protrusion is equal to the maximum value of the gap between the outer side panel and the door.

[0009] Optionally, the third protrusion is disposed on one side of the second protrusion in the third direction, and the dimension of the third protrusion in the second direction is greater than the dimension of the second protrusion in the second direction, where the third direction is perpendicular to the first direction and the second direction; and / or, the tooling body is integrally formed with at least one of the first protrusion, the second protrusion, and the third protrusion.

[0010] Optionally, the tooling body includes a first end face and a second end face oppositely arranged in the second direction. The second end face is closer to the first protrusion than the first end face, and the second end face forms the first mark; and / or, the first mark extends to one end of the tooling body along the direction away from the fitting portion.

[0011] Optionally, the tooling body and the first protrusion are integrally formed.

[0012] Optionally, the fitting portion is an arc surface, and the fitting portion is smoothly connected to the surface of the first protrusion close to the fitting portion.

[0013] Optionally, the tooling body is provided with a handle for the inspector to hold.

[0014] Optionally, the handle is disposed on a side of the fitting portion away from the first protrusion in the first direction, and a notch is provided on a side of the tooling body close to the first protrusion in the second direction, and a portion of the tooling body away from the notch in the second direction forms the handle.

[0015] During the process of installing the vehicle door, when using the vehicle door surface difference and gap detection tooling of the present invention to detect the surface difference and gap of the vehicle door, the fitting portion of the tooling body is in contact with the outer panel of the side wall. At this time, if the first mark interferes with the vehicle door, it is determined that the surface difference between the vehicle door and the outer panel of the side wall does not meet the requirements; if the first mark fits with the vehicle door, it is determined that the surface difference between the vehicle door and the outer panel of the side wall meets the requirements; if the surface of the first protrusion away from the fitting portion in the first direction interferes with the vehicle door, it is determined that the gap between the vehicle door and the outer panel of the side wall does not meet the requirements; if the surface of the first protrusion away from the fitting portion in the first direction fits with the vehicle door, it is determined that the gap between the vehicle door and the outer panel of the side wall meets the requirements. Thus, the surface difference and gap between the vehicle door and the outer panel of the side wall can be detected simultaneously, thereby improving the detection efficiency during the vehicle door installation process, and further improving the installation efficiency of the vehicle door. In addition, when the surface difference or gap between the vehicle door and the outer panel of the side wall does not meet the requirements, the position of the vehicle door can be adjusted so that both the first mark and the surface of the first protrusion away from the fitting portion in the first direction fit with the vehicle door, thereby making both the surface difference and the gap between the vehicle door and the outer panel of the side wall meet the requirements, and further improving the installation accuracy of the vehicle door. Therefore, the vehicle door surface difference and gap detection tooling of the present invention has the advantages of high vehicle door installation efficiency and high vehicle door installation accuracy.

[0033] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0034] As Figure 1 、 Figure 2 、 Figure 6 and Figure 7 shown, the door surface difference and gap detection tooling 10 of the embodiment of the present invention includes a tooling body 1 and a first protrusion 2. The tooling body 1 is provided with a first mark 11 and a fitting part 12. The first mark 11 and the fitting part 12 are arranged at intervals in a first direction. The first protrusion 2 is arranged between the fitting part 12 and the first mark 11 in the first direction. The first protrusion 2 protrudes from the tooling body 1 in a second direction and is connected to the tooling body 1. As Figures 3 to 5 、 Figure 8 and Figure 9As shown, the fitting portion 12 is used to fit with the outer panel 20 of the side wall. The maximum distance between the first mark 11 and the fitting portion 12 in the second direction is equal to the minimum value of the surface difference between the outer panel 20 of the side wall and the door 30. The minimum distance between the surface of the first protrusion 2 away from the fitting portion 12 in the first direction and the fitting portion 12 in the first direction is equal to the minimum value of the gap between the outer panel 20 of the side wall and the door 30. Wherein, the second direction is perpendicular to the first direction. The surface of the first protrusion 2 away from the fitting portion 12 in the first direction is the third mark 21.

[0035] During the process of installing the door, when using the door surface difference and gap detection tooling 10 of the embodiment of the present invention to detect the surface difference and gap of the door, the fitting portion 12 of the tooling body 1 fits with the outer panel 20 of the side wall. At this time, if the first mark 11 interferes with the door 30, it is determined that the surface difference between the door 30 and the outer panel 20 of the side wall does not meet the requirements; if the first mark 11 fits with the door 30, it is determined that the surface difference between the door 30 and the outer panel 20 of the side wall meets the requirements; if the surface of the first protrusion 2 away from the fitting portion 12 in the first direction interferes with the door 30, it is determined that the gap between the door 30 and the outer panel 20 of the side wall does not meet the requirements; if the surface of the first protrusion 2 away from the fitting portion 12 in the first direction fits with the door 30, it is determined that the gap between the door 30 and the outer panel 20 of the side wall meets the requirements. Thus, the surface difference and gap between the door 30 and the outer panel 20 of the side wall can be detected simultaneously, thereby improving the detection efficiency during the door installation process, and further improving the installation efficiency of the door. In addition, when the surface difference or gap between the door 30 and the outer panel 20 of the side wall does not meet the requirements, the position of the door 30 can be adjusted so that both the first mark 11 and the surface of the first protrusion 2 away from the fitting portion 12 in the first direction fit with the door 30, so that both the surface difference and gap between the door 30 and the outer panel 20 of the side wall meet the requirements, and further improving the installation accuracy of the door.

[0036] Therefore, the door surface difference and gap detection tooling 10 of the embodiment of the present invention can improve the installation efficiency and installation accuracy of the door 30.

[0037] To make the technical solution of the present invention easier to understand, the following takes the first direction being consistent with the up and down direction and the second direction being consistent with the left and right direction as an example to further describe the technical solution of the present invention. Wherein, the up and down direction is as Figure 1 、 Figure 2 、 Figures 4 to 9 shown, and the left and right direction is as Figure 1 、 Figures 4 to 9 shown.

[0038] For example, as Figure 1 、 Figure 2 、 Figure 6 and Figure 7As shown, the first protrusion 2 is provided on the lower side of the first mark 11, the fitting portion 12 is provided on the lower side of the first protrusion 2, and the first protrusion 2 protrudes rightward from the tooling body 1. The distance between the right ends of the first mark 11 and the fitting portion 12 is equal to the minimum value of the surface difference between the outer panel 20 of the side wall and the door 30; the distance between the lower surface of the first protrusion 2 and the lower end of the fitting portion 12 in the vertical direction is equal to the minimum value of the gap between the outer panel 20 of the side wall and the door 30. Wherein, the lower surface of the first protrusion 2 is the third mark 21.

[0039] In some embodiments, as Figure 1 and Figure 2 shown, the door surface difference and gap detection tooling 10 further includes a second protrusion 3. The first protrusion 2 protrudes from the tooling body 1 in the second direction and is connected to the tooling body 1, and the first mark 11 is arranged between the first protrusion 2 and the second protrusion 3 in the first direction. As Figure 5 shown, the second protrusion 3 has a second mark 31, and the maximum distance between the second mark 31 and the fitting portion 12 in the second direction is equal to the maximum value of the surface difference between the outer panel 20 of the side wall and the door 30.

[0040] For example, as Figure 1 shown, the second protrusion 3 protrudes rightward from the tooling body 1, and the second protrusion 3 is arranged on the lower side of the first mark 11. As Figure 5 shown, the maximum distance between the second mark 31 and the fitting portion 12 in the left-right direction is equal to the maximum value of the surface difference between the outer panel 20 of the side wall and the door 30.

[0041] When using the door surface difference and gap detection tooling 10 of the embodiment of the present invention to detect the surface difference and gap of the door, the fitting portion 12 of the tooling body 1 is attached to the outer panel 20 of the side wall. At this time, if the outer surface of the door 30 is located between the first mark 11 and the second mark 31, including the outer surface of the door 30 being attached to the first mark 11 or the second mark 31, it is determined that the surface difference between the door 30 and the outer panel 20 of the side wall meets the requirements; when the outer surface of the door 30 is on the side away from the second mark 31 of the first mark 11, or the outer surface of the door 30 is on the side away from the first mark 11 of the second mark 31, it is determined that the surface difference between the door 30 and the outer panel 20 of the side wall does not meet the requirements.

[0042] Thus, it is possible to more effectively determine whether the surface difference between the door 30 and the outer panel 20 of the side wall meets the requirements, and when the surface difference between the door 30 and the outer panel 20 of the side wall does not meet the requirements, the position of the door 30 can be adjusted more pertinently. It is beneficial to further improve the installation efficiency and installation accuracy of the door.

[0043] It can be understood that the difference between the minimum value of the surface difference between the outer panel 20 of the side wall and the door 30 and the basic surface difference value between the outer panel 20 of the side wall and the door 30 is the lower deviation (as Figure 5and Figure 9 In L1) of Figure 9 , the difference between the maximum value of the surface difference between the outer side panel 20 and the door 30 and the basic surface difference value between the outer side panel 20 and the door 30 is the upper deviation (such as Figure 5 in L3) of Figure 5 . Among them, L1 can be 0.75 mm and L3 can be 0.75 mm.

[0044] Optionally, as Figure 1 shown, the second protrusion 3 forms a second mark 31 on the end face away from the tool body 1 in the second direction.

[0045] For example, as Figure 1 shown, the right end face of the second protrusion 3 forms a second mark 31.

[0046] By using the end face of the second protrusion 3 as the second mark 31, it is beneficial to simplify the structure of the door surface difference and gap detection tool 10 and facilitate the machining and manufacturing of the door surface difference and gap detection tool 10.

[0047] Optionally, as Figure 1 and Figure 2 shown, the tool body 1 includes a first end face and a second end face arranged oppositely in the second direction, and the second end face is closer to the first protrusion 2 relative to the first end face. The part of the second end face located between the first protrusion 2 and the second protrusion 3 forms a first mark 11.

[0048] For example, as Figure 1 shown, the right end face of the tool body 1 located between the first protrusion 2 and the second protrusion 3 forms a first mark 11.

[0049] By using the end face of the tool body 1 as the first mark 11, it is beneficial to further simplify the structure of the door surface difference and gap detection tool 10 and further facilitate the machining and manufacturing of the door surface difference and gap detection tool 10.

[0050] Optionally, as Figure 1 and Figure 2 shown, the door surface difference and gap detection tool 10 further includes a third protrusion 4. The third protrusion 4 protrudes from the tool body 1 in the second direction and is connected to the tool body 1. The first mark 11 is arranged between the first protrusion 2 and the third protrusion 4 in the first direction. As Figure 5 shown, the maximum distance between the surface of the third protrusion 4 facing the first protrusion 2 and the surface of the first protrusion 2 facing away from the second protrusion 3 is equal to the maximum value of the gap between the outer side panel 20 and the door 30. Among them, the surface of the third protrusion 4 facing the first protrusion 2 and the surface of the first protrusion 2 facing away from the second protrusion 3 are the fourth mark 41.

[0051] For example, as Figure 1 and Figure 2As shown, the third protrusion 4 protrudes rightward from the tooling body 1 and is disposed below the first identifier 11. As Figure 5 shown, the distance between the upper surface of the third protrusion 4 and the lower surface of the first protrusion 2 is equal to the maximum value of the gap between the outer side panel 20 and the vehicle door 30. Among them, the upper surface of the third protrusion 4 is the fourth identifier 41.

[0052] When using the vehicle door surface difference and gap detection tooling 10 of the embodiment of the present invention to detect the surface difference and gap of the vehicle door, the fitting portion 12 of the tooling body 1 fits with the outer side panel 20. At this time, if one end of the vehicle door 30 adjacent to the outer side panel 20 is located between the first protrusion 2 and the third protrusion 4, including the situation where one end of the vehicle door 30 adjacent to the outer side panel 20 is in contact with the first protrusion 2 and the third protrusion 4, it is determined that the gap between the vehicle door 30 and the outer side panel 20 meets the requirements; when one end of the vehicle door 30 adjacent to the outer side panel 20 is not between the first protrusion 2 and the third protrusion 4, it is determined that the gap between the vehicle door 30 and the outer side panel 20 does not meet the requirements.

[0053] During specific detection, it can be determined whether the gap between the vehicle door 30 and the outer side panel 20 meets the requirements by whether the first protrusion 2 can be inserted between the outer side panel 20 and the vehicle door 30. When the first protrusion 2 can be inserted between the outer side panel 20 and the vehicle door 30, it is determined that the gap between the vehicle door 30 and the outer side panel 20 meets the requirements; when the first protrusion 2 cannot be inserted between the outer side panel 20 and the vehicle door 30, it is determined that the gap between the vehicle door 30 and the outer side panel 20 does not meet the requirements.

[0054] Thus, it can be more effectively determined whether the gap between the vehicle door 30 and the outer side panel 20 meets the requirements, and when the gap between the vehicle door 30 and the outer side panel 20 does not meet the requirements, the position of the vehicle door 30 can be adjusted more pertinently. This is beneficial to further improving the installation efficiency and installation accuracy of the vehicle door.

[0055] It can be understood that the difference between the minimum value of the gap between the outer side panel 20 and the vehicle door 30 and the basic gap value between the outer side panel 20 and the vehicle door 30 is the lower deviation (such as Figure 5 and Figure 9 the L2 in), and the difference between the maximum value of the gap between the outer side panel 20 and the vehicle door 30 and the basic gap value between the outer side panel 20 and the vehicle door 30 is the upper deviation (such as Figure 5 the L4 in). Among them, L2 can be 1.25 mm and L4 can be 1.25 mm.

[0056] Optionally, the third protrusion 4 is disposed on one side of the second protrusion 3 in the third direction, and the dimension of the third protrusion 4 in the second direction is greater than the dimension of the second protrusion 3 in the second direction, where the third direction is perpendicular to the first direction and the second direction.

[0057] To make the technical solution of the present invention easier to understand, the following takes the third direction being consistent with the front-rear direction as an example to further describe the technical solution of the present invention. Among them, the front-rear direction is as Figures 1 to 4 , Figures 6 to 8 shown.

[0058] For example, as Figure 1 and Figure 2 shown, the third protrusion 4 is provided on the front side of the second protrusion 3, and the dimension of the third protrusion 4 in the left-right direction is greater than the dimension of the second protrusion 3 in the left-right direction.

[0059] Thus, on the one hand, the size of the door surface difference and gap detection tooling 10 in the first direction can be reduced, which is beneficial to saving the material cost of the door surface difference and gap detection tooling 10; on the other hand, a step is formed between the third protrusion 4 and the second protrusion 3, and the step is used as the second mark 31, so that it is easier for the inspectors to observe whether the surface difference between the outer panel 20 of the side wall and the door 30 exceeds the second mark 31, that is, it is convenient for the inspectors to judge whether the surface difference between the outer panel 20 of the side wall and the door 30 meets the requirements, thereby being beneficial to further improving the detection efficiency of the door 30.

[0060] Optionally, the tooling body 1 is integrally formed with at least one of the first protrusion 2, the second protrusion 3 and the third protrusion 4. In other words, the tooling body 1, the first protrusion 2, the second protrusion 3 and the third protrusion 4 are all integrally formed; or, the tooling body 1 is integrally formed with one of the first protrusion 2, the second protrusion 3 and the third protrusion 4; or, the tooling body 1 is integrally formed with two of the first protrusion 2, the second protrusion 3 and the third protrusion 4.

[0061] By integrally forming the tooling body 1 with at least one of the first protrusion 2, the second protrusion 3 and the third protrusion 4, it is not only convenient for the processing and manufacturing of the door surface difference and gap detection tooling 10, but also beneficial to improving the structural strength of the door surface difference and gap detection tooling 10.

[0062] In some other embodiments, as Figure 6 and Figure 7 shown, the tooling body 1 includes a first end face and a second end face oppositely arranged along the second direction, the second end face is closer to the first protrusion 2 than the first end face, and the second end face forms the first mark 11.

[0063] For example, as Figure 6 shown, the right end face of the tooling body 1 forms the first mark 11.

[0064] By using the end face of the tooling body 1 as the first mark 11, it is beneficial to further simplify the structure of the door surface difference and gap detection tooling 10 and further facilitate the processing and manufacturing of the door surface difference and gap detection tooling 10.

[0065] Optionally, the first identifier 11 extends to one end of the tooling body 1 in a direction away from the fitting portion 12.

[0066] For example, as Figure 6 shown, the fitting portion 12 is provided on the upper side of the first identifier 11, and the first identifier 11 extends downward to the lower end of the tooling body 1.

[0067] By extending the first identifier 11 to one end of the tooling body 1 in a direction away from the fitting portion 12, the size of the first identifier 11 is made larger, which is convenient for judging whether the surface difference between the vehicle door 30 and the outer panel 20 of the side wall meets the requirements.

[0068] In the related art, the flat surface of the detection tooling for detecting the surface difference of the vehicle door is in contact with the outer panel of the side wall. However, the edge of the outer panel of the vehicle side wall is often an arc surface. When the flat surface of the detection tooling contacts the arc surface of the outer panel of the side wall, it is impossible to ensure the unity of the contact position between the flat surface of the detection tooling and the arc surface of the outer panel of the side wall. This results in the detection tooling having no uniquely determined detection reference, affecting the accuracy of the surface difference detection of the vehicle door. For example, when the same detection personnel perform two detections before and after, the detection tooling may contact different positions of the arc surface of the outer panel of the side wall, resulting in different detection references for the two detections before and after, and further resulting in different detection results for the front and rear sides, making it difficult to determine the specific surface difference value between the vehicle door and the outer panel of the side wall. In addition, the detection methods of different detection personnel may also be different, which will also result in different detection results of different detection personnel under different detection references.

[0069] In some embodiments, as Figure 2 and Figure 7 shown, the fitting portion 12 is an arc surface, and the fitting portion 12 is smoothly connected to the surface of the first protrusion 2 close to the fitting portion 12.

[0070] As Figure 5 and Figure 9 shown, by setting the fitting portion 12 as an arc surface and smoothly connecting the fitting portion 12 to the surface of the first protrusion 2 close to the fitting portion 12, the fitting portion 12 can be closely attached to the outer panel 20 of the side wall, and the fitting portion 12 can only be attached to the same arc surface of the outer panel 20 of the side wall.

[0071] Thus, the vehicle door surface difference and gap detection tooling 10 has a uniquely determined detection reference, ensuring the accuracy of the surface difference detection of the vehicle door 30.

[0072] Optionally, as Figure 1 , Figure 2 , Figure 7 and Figure 8 shown, the tooling body 1 is provided with a handle 13 for the detection personnel to hold.

[0073] By providing a handle 13 on the tooling body 1, inspectors can hold the door surface difference and gap detection tooling 10 through the handle 13, which facilitates the inspectors to perform inspection operations on the door 30, helps to further improve the inspection effect of the door 30, and thus further improves the installation efficiency of the door 30.

[0074] Optionally, as Figure 1 , Figure 2 , Figure 7 and Figure 8 shown, the handle 13 is provided on the side of the fitting portion 12 away from the first protrusion 2 in the first direction. A notch 14 is provided on the side of the tooling body 1 close to the first protrusion 2 in the second direction, and the part of the tooling body 1 away from the notch 14 in the second direction forms the handle 13.

[0075] For example, as Figure 1 , Figure 2 , Figure 5 , Figure 7 , Figure 8 and Figure 9 shown, the handle 13 is provided on the upper side of the fitting portion 12, and a notch 14 is provided on the right side of the tooling body 1. The notch 14 forms a gap between the tooling body 1 and the outer panel 20 of the side wall, and this gap can allow the hand of the inspector to be inserted to grasp the handle 13.

[0076] Through the above design of the tooling body 1, it is beneficial to further simplify the structure of the door surface difference and gap detection tooling 10, as well as reduce the material cost and weight of the door surface difference and gap detection tooling 10.

[0077] Optionally, the door surface difference and gap detection tooling 10 is integrally block-shaped.

[0078] It should be noted that Figures 1 to 5 the door surface difference and gap detection tooling 10 shown is used for the welding process of the vehicle. As Figure 5 shown, at this time, the door 30 includes the inner door panel 301 and the window frame reinforcement plate 302 of the door, and the door surface difference and gap detection tooling 10 is used to detect the surface difference and gap between the whole formed by the inner door panel 301 and the window frame reinforcement plate 302 of the door and the outer panel 20 of the side wall. Figures 6 to 9 The door surface difference and gap detection tooling 10 shown is used for the general assembly process of the vehicle.
