Description

Technical Field

[0001] This application relates to the technical field of detection technology for installing vehicles with opposite-opening doors, and particularly relates to a gap surface difference adjustment tooling and adjustment method for opposite-opening doors. Background Art

[0002] The front door assembly is composed of the front door sheet metal assembly and the door hinge assembly, and the rear door assembly is composed of the rear door sheet metal assembly and the door hinge assembly. Due to customer requirements, the door opening method has changed. The current mainstream door opening method is forward-opening the door, and the technical solutions for forward-opening the door are very mature. Due to project needs, it is necessary to change from forward-opening the door to opposite-opening the door, and the assembly adjustment design scheme for opposite-opening the door has changed greatly.

[0003] In the related art, the matching adjustment method for forward-opening the door is to use a strong magnet to flatten it to meet the surface difference requirement, and then use the fender tooling to assemble the fender. The matching adjustment method for forward-opening the door is: S1 Assemble the rear door, and then use a strong magnet to flatten the rear door and the side wall to meet the gap surface difference requirement; S2 Assemble the front door, and then use a strong magnet to flatten the front and rear doors to meet the gap surface difference requirement; S3 Assemble the fender through the integral fender assembly tooling to ensure the gap surface difference requirement between the fender and the front door.

A method for adjusting the gap surface difference when opening a vehicle door, characterized in that, The method uses the gap and flushness adjustment tool for opening a car door according to any one of claims 1 to 8, and the method comprises: Install the gap and flushness adjustment tool on the B-pillar of the vehicle under test, where the gap and flushness adjustment tool is located on the outer wall surface of the B-pillar of the vehicle; Using a positioning mechanism (3) to position the positioning bracket (1) on the B-pillar of the vehicle body in the X direction, using a clamping mechanism (4) to position the positioning bracket (1) on the B-pillar of the vehicle body in the Y direction, and using a locking mechanism (5) to position the positioning bracket (1) on the B-pillar of the vehicle body in the Z direction; The rear door (7) is closed, and the clearance surface difference between the rear door (7) and the side wall (6) of the vehicle body is measured. If the clearance surface difference between the rear door (7) and the side wall (6) of the vehicle body does not meet the design requirements, the Y-direction position of the rear door (7) is adjusted using the Y-direction adjustment structure (2) until the requirements are met, and then the rear door (7) is fixed; The front door (8) is closed, and the gap surface difference between the front door (8) and the rear door (7) is measured. If the measured gap surface difference between the front door (8) and the rear door (7) does not meet the design requirements, the Y-direction position of the front door (8) is adjusted using the Y-direction adjustment structure (2) until the requirements are met, and then the front door (8) is fixed; The fender (9) is assembled using a fender assembly tool, the fender assembly tool is matched with the front door (8) in the X direction through a positioning pin, and is matched with the front door (8) in the Y direction through a strong magnet, so that the gap surface difference between the fender (9) and the front door (8) meets the design requirements, and then the bolts are tightened and the fender assembly tool is removed; After the gap surface difference between the rear door (7) and the vehicle body side panel (6), the gap surface difference between the front door (8) and the rear door (7), and the gap surface difference between the front door (8) and the fender (9) meet the design requirements, the gap surface difference adjustment tool is removed.
