[0019] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0020] In the prior art, there are two solutions for assembling the hood and fender using tooling:

[0021] 1. Install the hood first and then the fender. In this solution, after the hood is installed, the hood must be opened to install the Z-direction installation point on the upper part of the fender. Before tightening the assembly, only the surface difference between the fender and the door can be confirmed, but the surface difference between the hood and the fender cannot be confirmed;

[0022] 2. Install the fender first and then the engine hood. In this solution, in order to establish the positioning connection between the engine hood and the fender, the positioning holes of the engine hood tooling are arranged on the fender. In order to lower the tooling, the engine hood must be opened and tightened. In this way, before assembly and tightening, only the gap and surface difference between the fender and the door can be confirmed, but the gap and surface difference between the engine hood and the fender cannot be confirmed.

[0023] Since two positioning components are arranged side by side and at intervals on the end face of the first support member facing the vehicle body and are detachably connected to the vehicle body, the first support member is supported by the vehicle body, and at the same time, the positioning of the first support member is realized. Since the first hood front limiting component is arranged on the top of the first support member and fits with the top of the front outer surface of the hood to limit the Z direction of the front part of the hood, the front Z direction of the hood is limited by the first hood front limiting member against the top of the front outer surface of the hood. Since the second hood front limiting component is arranged on the top of the first support member and fits with the end of the front outer surface of the hood to limit the X direction of the front part of the hood, the front X direction of the hood is limited by the second hood front limiting member against the end of the front outer surface of the hood. Since two gap adjusting components are arranged on the first support member and the adjusting end of the gap adjusting component can be arranged between the hood and the fender to limit the Y direction of the hood, the hood is centered in the Y direction between the two fenders through the adjusting end of the gap adjusting component, and the Y direction of the hood is limited. Moreover, the assembler can confirm the gap between the fender and the hood by visual inspection or measuring tools. If the gap is asymmetric, the adjusting end of the gap adjusting component can be used to make the gap between the hood and the two fenders symmetric, realizing online adjustment, avoiding repeated adjustment, and improving the assembly efficiency. Since the second support member is connected to the end of the first support member, the second support member is supported by the first support member, and at the same time, the X direction of the first support member is determined through the second support member. Since the first fender limiting component is arranged on the top of the second support member and fits with the Y-shaped surface and Z-shaped surface of the upper part of the fender to limit the Y direction and Z direction of the fender, the first fender limiting component is supported by the second support member, and the first fender limiting component abuts against the Y-shaped surface and Z-shaped surface of the upper part of the fender, realizing the Y direction and Z direction limitation of the fender. Since the fender positioning member is arranged at the bottom of the second support member and is connected to the lower part of the fender to limit the Z direction of the fender, the fender supports the second support member, and at the same time, the Z direction limitation of the fender is realized. Since at least two second fender limiting components are arranged on the second support member at intervals along the height direction of the vehicle body, and the second fender limiting components fit with the Y-shaped surface of the rear part of the fender, the Y-shaped surface of the door, the X-shaped surface of the rear part of the fender and the X-shaped surface of the door to limit the X direction and Y direction of the fender, the Y direction limitation of the rear part of the fender and the door is realized through at least two second fender limiting components. At the same time, the gap surface difference between the X-shaped surface of the rear part of the fender and the X-shaped surface of the door can also be ensured, improving the assembly efficiency. Finally, the hood and the fender are assembled on the vehicle body, and the assembly is completed in the state where the hood is closed. The positioning of the door and the fender is associated with the positioning of the hood and the fender, reducing the defect rate, and it is possible to identify whether there is a gap surface difference defect before the hood is assembled and tightened. When a gap surface difference is found, the gap surface difference can be adjusted online, avoiding repeated assembly and improving the assembly efficiency. Description of the Drawings

[0034] The first front hood limiting component 1-3 is arranged on the top of the first support member 1-1 and is in contact with the top of the front outer surface of the hood 3, and is used to limit the Z direction of the front part of the hood 3. In this embodiment, in order to ensure the positioning accuracy, the number of the first front hood limiting components 1-3 is two or more, and there is a spacing between every two adjacent first front hood limiting components 1-3.

In this embodiment, in order to ensure the positioning accuracy, the number of the first fender limiting components 2-2 is two or more, and there is a spacing between every two adjacent first fender limiting components 2-2.

[0040] The fender positioning member 2-3 is arranged at the bottom of the second support member 2-1 and is connected to the lower part of the fender 4, and is used to limit the Z direction of the fender 4. In this embodiment, the fender positioning member 2-3 can be a positioning pin.

[0041] At least two second fender limiting components 2-4 are arranged on the second support member 2-1 at intervals along the height direction of the vehicle body 5, and the second fender limiting components 2-4 are in contact with the Y-shaped surface of the rear part of the fender 4, the Y-shaped surface of the door, the X-shaped surface of the rear part of the fender 4 and the X-shaped surface of the door, and are used to limit the X direction and the Y direction of the fender 4.

[0042] In the prior art, there are two schemes for using a tooling to assemble the hood 3 and the fender 4:

[0043] 1. Install the hood 3 first and then the fender 4. In this solution, after the hood 3 is assembled, the hood 3 must be opened to assemble the Z-direction mounting points on the upper part of the fender 4. Before assembly and tightening, only the gap and surface difference between the fender 4 and the door can be confirmed, but the gap and surface difference between the hood 3 and the fender 4 cannot be confirmed.

[0044] 2. Install the fender 4 first and then the hood 3. In this solution, in order to establish the positioning connection between the hood 3 and the fender 4, the positioning holes of the hood 3 tooling are arranged on the fender 4. In order to lower the tooling, the hood 3 must be opened and tightened. In this way, before assembly and tightening, only the gap and surface difference between the fender 4 and the door can be confirmed, but the gap and surface difference between the hood 3 and the fender 4 cannot be confirmed.

[0045] Since the two positioning components 1-2 are arranged side by side and at intervals on the end face of the first support member 1-1 facing the vehicle body 5 and are detachably connected to the vehicle body 5, the first support member 1-1 is supported by the vehicle body 5, and at the same time, the positioning of the first support member 1-1 is realized. Since the first front hood limiting component 1-3 is arranged on the top of the first support member 1-1 and is in contact with the top of the front outer surface of the hood 3 to limit the Z direction of the front part of the hood 3, the front part of the hood 3 is limited in the Z direction by the first front hood limiting member against the top of the front outer surface of the hood 3. Since the second front hood limiting component 1-4 is arranged on the top of the first support member 1-1 and is in contact with the end of the front outer surface of the hood 3 to limit the X direction of the front part of the hood 3, the front part of the hood 3 is limited in the X direction by the second front hood limiting member against the end of the front outer surface of the hood 3. Since the two clearance adjusting components 1-5 are arranged on the first support member 1-1, and the adjusting end of the clearance adjusting component 1-5 can be arranged between the hood 3 and the fender 4 to limit the Y direction of the hood 3, the hood 3 is centered in the Y direction between the two fenders 4 through the adjusting end of the clearance adjusting component 1-5, realizing the Y-direction limiting of the hood 3. Moreover, the assembly personnel can confirm the clearance between the fender 4 and the hood 3 by visual inspection or measuring tools. If the clearance is asymmetric, the adjusting end of the clearance adjusting component 1-5 can be used to make the clearance between the hood 3 and the two fenders 4 symmetric, realizing on-line adjustment, avoiding repeated adjustment, and improving the assembly efficiency. Since the second support member 2-1 is connected to the end of the first support member 1-1, the second support member 2-1 is supported by the first support member 1-1, and at the same time, the X direction of the first support member 1-1 is determined through the second support member 2-1. Since the first fender limiting component 2-2 is arranged on the top of the second support member 2-1 and is in contact with the Y-shaped surface and Z-shaped surface of the upper part of the fender 4 to limit the Y direction and Z direction of the fender 4, the first fender limiting component 2-2 is supported by the second support member 2-1, and the first fender limiting component 2-2 abuts against the Y-shaped surface and Z-shaped surface of the upper part of the fender 4, realizing the Y-direction and Z-direction limiting of the fender 4. Since the fender positioning member 2-3 is arranged at the bottom of the second support member 2-1 and is connected to the lower part of the fender 4 to limit the Z direction of the fender 4, the second support member 2-1 is supported by the fender 4, and at the same time, the Z-direction limiting of the fender 4 is realized. Since at least two second fender limiting components 2-4 are arranged on the second support member 2-1 at intervals in the height direction of the vehicle body 5, and the second fender limiting components 2-4 are in contact with the Y-shaped surface of the rear part of the fender 4, the Y-shaped surface of the door, the X-shaped surface of the rear part of the fender 4 and the X-shaped surface of the door to limit the X direction and Y direction of the fender 4, the Y-direction limiting of the rear part of the fender 4 and the door is realized through at least two second fender limiting components 2-4, and at the same time, the clearance surface difference between the X-shaped surface of the rear part of the fender 4 and the X-shaped surface of the door can also be ensured, improving the assembly efficiency.Finally, the hood 3 and the fender 4 are assembled on the vehicle body 5, and the assembly is completed with the hood 3 closed. The positioning of the door and the fender 4 is associated with the positioning of the hood 3 and the fender 4, reducing the defect rate. Moreover, whether there are gap and flushness defects can be identified before the hood 3 is assembled and tightened. When gap and flushness are found, the gap and flushness can be adjusted online to avoid repeated assembly and improve the assembly efficiency.
