[0048] Specifically, as Figure 7 shown, Figure 7 is Figure 5 a structural schematic view of an embodiment of the pressing assembly, the pressing assembly 27 comprises a connecting block 271 and a pressing block 272, the pressing block 272 is movably connected with the connecting block 271, the connecting block 271 is connected with the second cross beam 22, and the pressing block 272 is used for pressing connection with the end plate of the longitudinal beam of the automobile. Optionally, the pressing block 272 can be movably connected with the pressing block 272 through an elastic member 273. In this way, the fixing mode of the pressing assembly 27 is simple, and the fixing reliability is also higher. Through the pressing and fixed connection of the pressing assembly 27, the stability of the second tooling 20 on the vehicle body is ensured.

[0049] Further, as Figure 5 shown, the second cross beam 22 is provided with an alignment assembly 28, the alignment assembly 28 is used for fixing the first tooling 10 to align the first tooling 10, so that the first tooling 10 is installed on the vehicle body.

In some specific embodiments, as Figure 8 shown, the alignment assembly 28 comprises a sliding rail 281, a sliding block 282, an adapter plate 283 and a positioning pin 284. Among them, the sliding rail 281 is fixed on the second cross beam 22, the sliding block 282 is movably connected with the sliding rail 281, the adapter plate 283 is connected with the sliding block 282, and the positioning pin 284 is connected with the adapter plate 283. Two positioning pins 284 can be provided to position the X direction and the Z direction of the first tooling 10, or the position of the positioning pin 284 in the X direction and the Z direction can be adjusted by adjusting the gasket. The sliding block 282 relative to the sliding rail 281 can drive the positioning pin 284 to move, which can ensure that the first tooling 10 slides in the Y direction to realize the adhesion with the vehicle body. Referring to Figure 9 shown, Figure 9 is a structural schematic view of an embodiment of the first tooling, the second tooling and the vehicle body, the positioning pin 284 is used for hanging the first tooling 10 to fix the first tooling 10 to the lower end of the vehicle body.

In this way, the structural stability of the entire frame of the second tooling 20 can be improved.

[0052] The second tooling 20 is equivalent to a robotic arm. Its structure is simple and its operation is straightforward. Fixed to the vehicle body, it can move directly with the body, avoiding interference from other factors that could affect its effectiveness. Furthermore, its connection to the car's fender shortens the dimensional chain.

[0053] like Figure 10 and Figure 11 As shown, Figure 10 This is a schematic diagram of the structure of an embodiment of the third tooling in the automotive front-end module mounting fixture provided in this application. Figure 11 yes Figure 10 A structural schematic diagram of the third tooling from another perspective.

[0054] like Figure 12 As shown, Figure 12 This is a structural schematic diagram of an embodiment of the third tooling and the front-end module. The function of the third tooling 30 is to cooperate with the upper end of the front-end module 40. The third tooling 30 includes a positioning frame (not shown in the figure), which includes a first positioning frame 31 and a second positioning frame 32. The first positioning frame 31 is connected to the second positioning frame 32.

[0057] The third tooling 30 may also include: a third positioning pin 35 and a fourth positioning pin 36. The third positioning pin 35 and the fourth positioning pin 36 are respectively located at both ends of the first positioning frame 31. The third positioning pin 35 and the fourth positioning pin 36 are used to cooperate with the positioning holes on the left and right fenders of the car. In this way, the dimensional chain can be shortened, and this position can be matched in the X direction by adjusting the shims.

[0058] The second positioning frame 32 is equipped with a positioning component 38, which is used to cooperate with the front-end module 40 to position the front-end module 40 in the X and Y directions.

[0059] Furthermore, such as Figure 10As shown, the positioning assembly 38 can include a first positioning member 381, a second positioning member 382, and a third positioning member 383, wherein the second positioning member 382 is arranged between the first positioning member 381 and the third positioning member 383.

That is, the second positioning member 382 is arranged protruding from the first positioning member 381 and the second positioning member 382. The second positioning member 382 is used to cooperate with the front end module 40 to achieve Y-direction positioning of the front end module 40. And this position can also be achieved by adjusting the gasket to match the Y-direction. The first positioning member 381 and the third positioning member 383 cooperate with the front end module 40 to achieve X-direction positioning of the front end module 40, and this position can be achieved by adjusting the gasket to match the X-direction.

[0060] The third tooling 30 provides X-direction and Y-direction positioning for installation of the front end module 40.

[0061] For example, the process of installing the front end module 40 by using the first tooling 10, the second tooling 20, and the third tooling 30 is as follows:

[0062] 1. One person on the left and one person on the right at a certain station of the chassis line assemble the second tooling 20 to the vehicle body, manually assemble the first tooling 10 to the second tooling 20, and fix the first tooling 10 to the vehicle body, specifically, the first tooling 10 can be fixed to the vehicle body by tightening the fasteners. After the first tooling 10 is installed, the second tooling 20 is removed.

[0063] 2. The front end module 40 is disassembled offline (without a front bumper beam), and is transported to the chassis line offline station by logistics.

[0064] 3. The mechanical hand operator operates the mechanical hand to grab the front end module 40 and moves it to the chassis line, and at the same time during the grabbing process, two people on the line take the third tooling 30 and reach the working position before the mechanical hand arrives, and install the third tooling 30 on the vehicle body, then assist in assembling the front end module 40 by using the third tooling 30, complete the X-direction and Y-direction alignment by using the third tooling 30, and support the front end module 40 on the first tooling 10 to assist in the fixed installation of the front end module 40, and then remove the second tooling 20.

[0065] 4. Two people go online to pick up the front bumper beam and assemble it onto the vehicle body. First, tighten the X-direction bolts (diagonally and symmetrically), and then tighten the Y-direction bolts (symmetrically).

[0066] 5. Two people on the line disassemble the first tooling 10 and put it back into the transfer trolley; then wait for the personnel to return the trolley to the chassis line workstation.

[0067] In summary, the above assembly solution meets the 60 JPH requirement and, compared to the robotic arm solution, reduces the cost per vehicle by 4.6 yuan, reduces consistency investment by 340,000 yuan, increases the assembly qualification rate by 23%, reduces the number of rework personnel, and allows for timely handling of abnormal issues.
