[0036] The installation beam 1 includes a first beam section 11, a second beam section 12 and a beam body 13. The beam body 13 extends in the left-right direction. The first beam section 11 and the second beam section 12 are respectively connected to two ends of the beam body 13 in the left-right direction at an angle.

[0037] The front cover simulation block 3 is arranged on the cross beam body 13 for detecting the position of the front cover; the left fender simulation block 4 is arranged on the first cross beam section 11 for detecting the position of the left fender, and the right fender simulation block 5 is arranged on the second cross beam section 12 for detecting the position of the right fender.

Secondly, the mounting crossbeam 1 includes a first crossbeam section 11, a second crossbeam section 12 and a crossbeam body 13. The mounting crossbeam 1 is constructed as a beam structure and adopts a three-section design, which can effectively simplify the structure of the mounting frame of the detection device. The detection device can be positioned at the front end of the body-in-white without the assistance of multiple people, which is convenient for operators to operate. In addition, the first cross beam section 11 and the second cross beam section 12 are respectively connected at an angle to the two ends of the cross beam body 13 along the left and right directions. The cross beam body 13 can be opposite to the position of the front cover, which is convenient for the installation of the front cover simulation block 3 for position detection of the front cover. The first cross beam section 11 can be opposite to the position of the left fender, which is convenient for the installation of the left fender simulation block 4 for position detection of the left fender. The second cross beam section 12 can be opposite to the position of the right fender, which is convenient for the installation of the right fender simulation block 5 for position detection of the right fender.

[0039] Optionally, refer to Figures 2 to 4 As shown, the body-in-white front end detection device further includes a front cover adjustment mechanism 6, which is disposed on the crossbeam body 13 to adjust the surface difference between the front cover and the left fender panel and the right fender panel.

[0040] For example, in the specific adjustment process, the front cover on the body-in-white can be opened first, and the front-end detection device of the body-in-white disclosed in the present invention can be positioned at the front end of the body-in-white by using the positioning mechanism 2 mentioned above, and then the front cover can be lowered, and the first face difference between the front cover and the front cover simulation block 3 can be measured by using a dial indicator, and then the second face difference between the left fender and the left fender simulation block 4 can be measured by using a dial indicator, and then the third face difference between the right fender and the right fender simulation block 5 can be measured by using a dial indicator. If the difference between the first face difference and the second face difference and / or the difference between the first face difference and the third face difference exceeds the required range, the position of the front cover can be adjusted by using the front cover adjustment mechanism 6 so that the front cover is flush with the left fender and the right fender. The front cover adjustment mechanism 6 can be constructed as any appropriate adjustment structure, and the present disclosure does not limit this.

[0041] Optionally, refer to Figures 2 to 4 As shown, the front cover adjustment mechanism 6 includes a first adjustment member 61 and a second adjustment member 62. Both the first adjustment member 61 and the second adjustment member 62 can be used to adjust the installation position of the front cover in the up and down directions. The first adjustment member 61 is arranged at the first end of the beam body 13 along the left and right directions, and the second adjustment member 62 is arranged at the second end of the beam body 13 along the left and right directions.

[0042] In this embodiment, the first adjustment member 61 and the second adjustment member 62 can be adjusted separately or simultaneously, and the present disclosure does not limit this. For example, the face difference between the front cover and the left fender meets the requirements, but the face difference between the front cover and the right fender does not meet the requirements. The first adjustment member 61 is set at the left end of the crossbeam body 13, and the second adjustment member 62 is set at the right end of the crossbeam body 13. In this case, there is no need to adjust the first adjustment member 61, and only the second adjustment member 62 needs to be adjusted. The first adjustment member 61 and the second adjustment member 62 can be constructed in any appropriate shape and structure, and the present disclosure does not limit this.

[0043] In one embodiment, referring to Figure 3 As shown, the first adjustment member 61 includes a first mounting block 611 and a first adjusting screw 612. The first mounting block 611 is arranged at the first end of the beam body 13 in the left-right direction, and the first mounting block 611 is formed with a first threaded hole extending in the up-down direction, and the first adjusting screw 612 is adjustably arranged in the first threaded hole in the up-down direction. The operator can rotate the first adjusting screw 612 to make the first adjusting screw 612 move in the up-down direction, and the first adjusting screw 612 can support the front cover so that the front cover is stably located in the adjusted position, and then use a dial indicator to detect the adjusted position to adjust the front cover to a position that meets the requirements.

[0044] In another embodiment, referring to Figure 4 As shown, the second adjustment member 62 may also include a second mounting block 621 and a second adjusting screw 622, the second mounting block 621 being disposed at the second end of the beam body 13 in the left-right direction, and the second mounting block 621 being formed with a second threaded hole extending in the up-down direction, and the second adjusting screw 622 being adjustably disposed in the second threaded hole in the up-down direction. The operator may rotate the second adjusting screw 622 to move the second adjusting screw 622 in the up-down direction, and the second adjusting screw 622 may support the front cover so that the front cover is stably located in the adjusted position, and then the adjusted position is detected using a dial indicator to adjust the front cover to a position that meets the requirements. In addition, the second adjusting screw 622 is easy to adjust and has high adjustment accuracy.

[0045] Optionally, refer to Figure 1 and Figure 2As shown, the front end detection device of the body-in-white may further include a left fender bracket simulation block 7 and a right fender bracket simulation block 8. The left fender bracket simulation block 7 is arranged at the first cross beam section 11 to detect the position of the left fender bracket, and the right fender bracket simulation block 8 is arranged at the second cross beam section 12 to detect the position of the right fender bracket. For example, for the detection of the right fender bracket, a dial indicator may also be used for detection. The detection method is to use the dial indicator to detect the gap between the right fender bracket and the right fender bracket simulation block 8. If the gap is too large and exceeds the required range, the operator adjusts the installation position of the right fender bracket to adjust the gap so that the installation position of the right fender bracket meets the requirements.

[0046] In another embodiment, referring to Figure 1 and Figure 2 As shown, the front end detection device of the body-in-white may further include a left front bumper bracket simulation block 9 and a right front bumper bracket simulation block 10.

By arranging the left front bumper bracket simulation block 9 and the right front bumper bracket simulation block 10, the position of the left front bumper bracket and the right front bumper bracket can be detected. For example, a dial indicator can be used for detection. The specific detection method is not described in detail here.
