Description

Technical Field

[0001] This utility model belongs to the field of automotive assembly tooling technology, and relates to tooling in the automotive manufacturing process, specifically to a tooling for ensuring the gap between the front door and the triangular window of an automobile. Background Technology

[0002] In automotive body assembly, the matching accuracy between the front door and surrounding components directly affects the overall vehicle's sealing and appearance quality. Specifically, the clearance between the triangular window and the front door needs to meet design requirements. Currently, most front door installation processes typically use fender contour blocks to adjust the X / Z-axis positioning of the front door, and then the fender is adjusted in the X / Y / Z-axis according to the front door's posture. While this method ensures the relative positional stability of the front door and fender, it also introduces other problems:

[0003] 1. Accumulation of dimensional chain deviations: Manufacturing tolerances and assembly errors of various body parts will be transmitted to the matching area of ​​the front door and the triangular window through the dimensional chain. Since the triangular window is a non-adjustable part, the Z-direction gap between the front door and the triangular window is difficult to control.

[0004] 2. Insufficient redundancy in positioning reference: It relies on the fender contour block as the main adjustment method, but the fender itself needs to be installed by adjustment method due to the assembly sequence restriction, and its positioning accuracy is difficult to meet the high matching requirements.

[0005] 3. Dynamic error amplification effect: Fluctuations in the installation accuracy of the door hinges will further affect the posture of the front door. Traditional methods cannot directly constrain the Z-axis degree of freedom of the triangular window area through tooling, which exacerbates the problem of uneven gaps. Utility Model Content
