Therefore, in order to improve the stability of the matching dimensions of the headlights 900, the front signal lights 800 and the front bumper, a vehicle front end assembly jig 100 and an assembly method are provided.

The stability of the positioning of the headlight undermount bracket assembly 400 is further ensured.

[0069] like Fig.10 , Fig.13 and Fig.14As shown, in other embodiments, a second limiting block 145 is used to fit with the headlight mounting bracket assembly 500 in the X direction and Y direction of the vehicle, and another second limiting clamp is used to clamp the headlight mounting bracket assembly 500. In some embodiments, the second limiting block 145 includes a groove, and the groove is provided with a limiting surface a1451 for limiting along the X direction of the vehicle and a limiting surface b1452 for limiting along the Y direction of the vehicle. Correspondingly, the headlight mounting bracket assembly 500 fits with the limiting surface a1451 along the X direction of the vehicle, thereby limiting in the X direction of the vehicle; the headlight mounting bracket assembly 500 fits with the limiting surface b1452 along the Y direction of the vehicle, thereby limiting in the Y direction of the vehicle, and the headlight mounting bracket assembly 500 can be self-positioned in the Z direction through the mounting surface. Then, the headlight mounting bracket assembly 500 is fitted and limited with the skeleton of the vehicle front end assembly assembly jig 100 along the X direction of the vehicle by the second limiting clamp b144. The stability of the positioning of the headlight mounting bracket assembly 500 is further ensured.

[0070] like Figure 1 As shown, in some embodiments, the frame includes a first frame 151 and a second frame 161; the first positioning assembly 110 and the first limiting assembly 130 are both mounted on the first frame 151 to form a first fixture 150; the first fixture 150 is arranged above the front frame 200; the second positioning assembly 120 and the second limiting assembly 140 are both mounted on the second frame 161 to form a second fixture 160; the first fixture 150 is arranged in front of the front frame 200 and the front bumper assembly of the body-in-white. The upper crossbeam mounting plate 300 can be limited in the X direction, Y direction and Z direction of the vehicle relative to the front frame 200 by the first fixture 150; the headlight mounting bracket assembly 500 and the headlight lower mounting bracket assembly 400 can be limited in the X direction, Y direction and Z direction of the vehicle relative to the front frame 200 by the second fixture 160.

[0071] like Figure 1 As shown, in some embodiments, the first fixture 150 and the second fixture 160 are split. It is convenient to position the upper crossbeam mounting plate 300 of the water tank by the first fixture 150, and to position the headlight mounting bracket assembly 500 and the headlight lower mounting bracket assembly 400 by the second fixture 160. The operation contents can be split to reduce the weight of a single tool.

[0072] like Fig.11 As shown, in some embodiments, the second fixture 160 also includes a fixing clip 162 for fixing the second fixture 160 to the body-in-white; the second fixture 160 can be fitted to the body-in-white through the fixing clip 162.

[0073] like Fig.11 , Fig.15 and Fig.16 As shown, in other embodiments, when the positioning of the front-end assembly of the vehicle also includes the front center mounting bracket 600, the second fixture 160 also includes a limiting portion 163, and the limiting portion 163 is used to fit the front center mounting bracket 600 in the X direction, Y direction and Z direction of the vehicle. The limiting portion 163 includes a limiting portion a1631, a limiting portion b1632 and a limiting portion c1633. The limiting portion a1631 can provide a limit in the Z direction of the vehicle. The limiting portion a1631 can be an adsorption magnet to provide an adsorption force for the front center mounting bracket 600 in the Z direction of the vehicle to prevent the front center mounting bracket 600 from falling; the limiting portion b1632 can provide a limit in the X direction of the vehicle, and the limiting portion c1633 can provide a limit in the Y direction of the vehicle, so that the front center mounting bracket 600 is limited in the limiting portion 163 along the X direction, Y direction and Z direction of the vehicle. The front fender mounting bracket 600 can be used to support the front fender assembly to ensure the Z-direction position of the front fender assembly.

[0074] Therefore, when installing the headlight mounting bracket assembly 500 and the headlight under-mounting bracket assembly 400, the headlight mounting bracket assembly 500 and the headlight under-mounting bracket assembly 400 can be installed on the second fixture 160 in advance, and the second fixture 160 is positioned and installed on the white vehicle body through the front end frame 200, thereby improving the installation efficiency.

[0075] In a second aspect of the present application, a vehicle front end assembly method based on the above-mentioned vehicle front end assembly assembly jig 100 is provided, wherein the vehicle lamp mounting assembly includes a water tank upper crossbeam mounting plate, a headlight lower mounting bracket assembly and a headlight mounting bracket assembly;

[0076] The installation method of the water tank upper crossbeam mounting plate 300 comprises the following steps:

[0077] The water tank upper cross beam mounting plate 300 is pre-installed on the body-in-white; it can be understood that the water tank upper cross beam mounting plate 300 has a fitting surface that cooperates with the cross beam 216 of the body, that is, the water tank upper cross beam mounting plate 300 can be placed on the corresponding body to complete the pre-installation. Since the position of the column 217 of the front end frame 200 is fixed, the water tank upper cross beam mounting plate 300 can be directly fitted with the column 217 of the front end frame 200 and the cross beam 216 of the body to complete the pre-installation.

[0078] The front end frame 200 is installed on the body-in-white; that is, the upper cross beam 216 of the front end frame 200 is installed on the column 217 of the front end frame 200 .

[0079] The multiple positioning members of the vehicle front end assembly jig 100 are matched with the front end frame 200, so as to generate constraints in at least one direction of the vehicle's X direction, Y direction, and Z direction, so that the multiple positioning members are positioned relative to the front end frame 200 in the vehicle's X direction, Y direction, and Z direction. That is, the first jig 150 of the vehicle front end assembly jig 100 can be positioned relative to the front end frame 200.

[0080] The limiting piece of the vehicle front-end assembly jig 100 is matched with the water tank upper cross beam mounting plate 300, so as to generate a constraint in at least one direction of the vehicle's X direction, Y direction, and Z direction, and the water tank upper cross beam mounting plate 300 is limited relative to the front-end frame 200 in the vehicle's X direction, Y direction, and Z direction through the first jig 150. That is, the water tank upper cross beam mounting plate 300 can be positioned relative to the front-end frame 200 through the first jig 150.

[0081] Connect and fix the water tank upper cross beam mounting plate 300 to the vehicle body; that is, connect and fix the water tank upper cross beam mounting plate 300 to the corresponding mounting holes of the white body.

[0082] The vehicle front end assembly jig 100 is removed; after the water tank upper crossbeam mounting plate 300 is installed, the first jig 150 can be removed along the Z direction of the vehicle. The operation is simple, convenient and fast.

[0083] When the second fixture 160 further includes the limiting portion 163, the method for installing the headlight lower mounting bracket assembly 400 and the headlight mounting bracket assembly 500 includes the following steps:

[0084] The limiting piece and the limiting portion 163 of the vehicle front end component assembly jig 100 are matched with the front headlight mounting bracket assembly 400, the front headlight mounting bracket assembly 500 and the front fender mounting bracket 600 respectively, that is, the left front headlight mounting bracket assembly 400, the right front headlight mounting bracket assembly 400, the left front headlight mounting bracket assembly 500, the right front headlight mounting bracket assembly 500 and the front fender mounting bracket 600, a total of five parts, can be installed in advance on the second jig 160 of the vehicle front end component assembly jig 100. Since the five parts are relatively scattered, the five parts are first installed on the second jig 160, which improves the installation efficiency.

[0085] The positioning parts of the vehicle front-end component assembly jig 100 are matched with the front-end frame 200; thereby, the above-mentioned five parts are positioned relative to the front-end frame 200 in the X-direction, Y-direction and Z-direction of the vehicle. Since the five parts are positioned on the second jig 160 in advance, the five parts are limited relative to the front-end frame 200 in the X-direction, Y-direction and Z-direction of the vehicle by the second jig 160.

[0086] The headlight lower mounting bracket assembly 400, the headlight mounting bracket assembly 500 and the front bumper center mounting bracket 600 are mounted on the body-in-white; that is, the five parts are connected and fixed to the corresponding mounting holes of the body-in-white.

[0087] The vehicle front end assembly fixture 100 is removed. After the five parts are connected and fixed to the corresponding mounting holes of the body-in-white, the second fixture 160 can be removed along the X direction of the vehicle, which is simple, convenient and quick to operate.

[0088] Therefore, the present application can use the first jig 150 and the second jig 160 to respectively install the seven parts, namely, the left mounting plate of the upper cross beam 216 of the water tank, the right mounting plate of the upper cross beam 216 of the water tank, the left front headlight mounting bracket assembly 500, the right front headlight mounting bracket assembly 500, the left front headlight lower mounting bracket assembly 400, the right front headlight lower mounting bracket assembly 400, and the front center mounting bracket 600. The seven parts are uniformly installed by the first jig 150 or the second jig 160 with the front end frame 200 as the positioning reference, which reduces the weight of the jig and can also split the mounting bracket operation to facilitate the balance between the installation processes. Compared with using a jig for positioning and installation of each part, two jigs are smaller in size than multiple jigs and are more convenient to use.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
