[0034] Example 1

[0035] In a typical embodiment of the present application, referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , a large lid assembly aid includes a first auxiliary tool, a second auxiliary tool and a third auxiliary tool, which are used together during large lid assembly to achieve the precise gap requirements between the large lid and the side wall and the front door after assembly.

[0036] As shown in Figure 3 , the third auxiliary tool includes two rear end Y direction limiting components of the lid, which have a side wall profiled block 113 that can be attached to the side wall. The side wall profiled block 113 is provided with a gap block 116 between the lid and the side wall. The side wall profiled block 113 is also provided with a strong magnet, which is attached to the left and right side of the vehicle body through the strong magnet, achieving the requirement of quick installation. In this embodiment, the side wall profiled block 113 is provided with two strong magnets, specifically a first strong magnet 114 and a second strong magnet 115. It can be understood that the number of strong magnets is not limited to two in this embodiment, and can be selected according to actual conditions, as long as it can ensure the firm installation of the side wall profiled block 113.

[0037] The side wall profiled block 113 can ensure that the third auxiliary tool is attached to the side wall. In addition, by providing the gap block 116 between the lid and the side wall, the gap between the large lid and the side wall after assembly can be ensured to be consistent, so the thickness of the gap block 116 between the lid and the side wall is consistent with the gap between the lid and the side wall.

[0038] It is easy to understand that the third auxiliary tool includes two side contouring blocks 113, which are arranged on the two sides of the vehicle body respectively, and jointly assist in positioning the gap between the rear end of the large cover and the side wall, so as to ensure the positioning of the rear end of the large cover in the Y direction.

[0039] As shown in Figure 4 The second auxiliary tool includes two rear end X limiting components of the large cover, and the rear end X limiting component of the large cover has a front door contouring block 117 which can be attached to the front door, and the front end of the front door contouring block 117 is provided with a large cover and front door gap block.

[0040] Specifically, in the embodiment, two large cover and front door gap blocks are arranged on the front door contouring block 117, which are a first large cover and front door gap block 121 and a second large cover and front door gap block 122. It can be understood that the number of large cover and front door gap blocks is not limited to two in the embodiment, and can be increased or decreased according to actual conditions, as long as the purpose of ensuring the gap can be achieved.

[0041] In the embodiment, a strong magnet is further arranged on the front door contouring block 117, which is adsorbed on the vehicle body by the strong magnet to meet the requirement of quick installation. In the embodiment, three strong magnets are arranged on the front door contouring block 117, specifically a third strong magnet 118, a fourth strong magnet 119 and a fifth strong magnet 120, and the three strong magnets are uniformly distributed on the front door contouring block 117 to ensure that the front door contouring block 117 is stably adsorbed on the vehicle body on the left and right sides. It can be understood that the number of strong magnets on the front door contouring block 117 is not limited to three in the embodiment, and can be selected according to actual conditions, as long as the front door contouring block 117 can be firmly installed.

[0042] The front door contouring block 117 can ensure that the second auxiliary tool is attached to the front door, and the thickness of the large cover and front door gap block is consistent with the gap between the large cover and the front door, so that the gap between the large cover and the front door is consistent after the large cover is assembled.

[0043] It is easy to understand that the second auxiliary tool includes two front door contouring blocks 117, which are arranged on the two sides of the vehicle body respectively, and jointly assist in positioning the gap between the rear end of the large cover and the front door, so as to ensure the positioning of the rear end of the large cover in the X direction.

[0044] As shown in Figure 5 The front door contouring block 117 is specifically installed on the front door outer plate 123, and the side contouring block 113 is specifically installed on the side wall outer plate 124.

[0045] This embodiment, by setting a second auxiliary tooling and a third auxiliary tooling, includes a gap block 116 between the cover and the front door, and a gap block 116 between the cover and the side panel, which allows the cover to be directly positioned with the front door and the side panel. This ensures that the cover is positioned to the front door in the X direction and to the side panel in the Y direction when closed. During assembly, the status with the front door and the side panel can be directly displayed. After manual inspection to ensure that the requirements are met, the cover and hinge mounting nuts are tightened, which can meet the requirements for precise gaps between the cover and the front door, and between the cover and the side panel.

[0046] In addition, by adjusting the assembly sequence of the hood and fenders, the hood can be assembled first, followed by the fenders. This ensures that the hood, when closed, matches the gap between itself and the outer front door panel and the outer side panel through the gap block, meeting the appearance gap requirements before tightening the connecting nuts between the hood and the fenders.

[0047] Using the auxiliary tool in this embodiment, workers can directly inspect and then tighten the cover and cover hinge nuts during the assembly process, avoiding secondary adjustments. This ensures that the gap between the cover and the front door and side panels meets the design requirements in one go, directly improving assembly efficiency and quality.

After the bracket is installed, the two positioning pins are located at the end of the bracket near the windshield, and can be positioned to the vehicle body's water channel. Specifically, the two positioning pins are a first positioning pin 102 and a second positioning pin 103. The first positioning pin 102 is positioned to the vehicle body's water channel, and the second positioning pin 103 is also positioned to the vehicle body's water channel.

[0051] The first positioning pin 102 is a round pin, and the second positioning pin 103 is a diamond pin. The round pin can control the X / Y position of the first auxiliary tooling 101 on the vehicle body, and the diamond pin can control the X position of the first auxiliary tooling 101 on the vehicle body.

[0052] The Y-axis positioning component also includes two support blocks mounted on the bracket to serve as free support for the wheel arch assembly, and two support blocks to serve as free support for the fender bracket.

[0053] Specifically, the two support blocks of the support wheel cover assembly are a first support block 104 and a second support block 105, both of which are arranged at the rear end of the support X. The first support block 104 is arranged close to the first positioning pin 102, and the second support block 105 is arranged close to the second positioning pin 103. Among them, the first support block 104 is positioned to the left wheel cover assembly in the Z direction of the vehicle body, and the second support block 105 is positioned to the right wheel cover assembly in the Z direction of the vehicle body.

[0054] The two support blocks used as support fender brackets are a third support block 106 and a fourth support block 107, both of which are arranged at both ends of the support Y. Among them, the third support block 106 is positioned to the left fender bracket of the vehicle body, and the fourth support block 107 is positioned to the right fender bracket of the vehicle body.

[0055] As shown in Figure 2 The cover support part includes at least two support blocks arranged at one end of the support X, and at least two support blocks arranged at the other end of the support X.
