Description

TECHNICAL FIELD

[0001] The present application relates to the field of vehicle door production equipment, in particular to a white body door assembly gap adjusting device and its using method. BACKGROUND

[0002] In the process of manufacturing the automobile white body, the assembly gap between the door and the adjacent parts is one of the key indicators to measure the manufacturing precision and quality of the whole vehicle.

[0003] Whether the gap is uniform and compliant directly affects the appearance quality, wind noise level and door closing feel of the vehicle.

[0004] At present, the adjustment of the door gap on the door assembly line is usually divided into two stages: White body stage adjustment: before the installation of the interior parts of the door (such as glass, glass lifter, door lock, interior panel, etc.), the naked door is preliminarily positioned and the gap is adjusted.

[0005] Post-assembly stage adjustment: after all the interior parts are installed, the final state of the door gap is reviewed and fine-tuned.

[0006] However, the existing adjustment method has significant drawbacks: Firstly, in the adjustment of the white body stage, the operator usually relies on simple plug gauges or visual experience to make judgments, and uses tools to adjust the hinge bolts; this method lacks scientific quantification simulation and cannot predict the weight impact after the installation of the interior parts.

[0007] Due to the considerable weight of the interior parts of the door (especially the glass and the lifter), the loading of the door hinge will cause a certain elastic deformation, resulting in the sinking or deviation of the whole door; this leads to the change of the perfect gap adjusted in the white body stage after the assembly, and the problem of uneven or even excessive gap.

[0008] The existing one generally ensures the installation gap between the door and the white body through auxiliary tools, such as the content disclosed in patent CN 103358250A - a white body door assembly gap adjusting auxiliary tool and its adjusting method, but based on the content of the patent; the patent can theoretically ensure the assembly gap between the door and the white body under specific working conditions; but the patent cannot realize that the assembly gap between the door and the white body without interior parts is equivalent to the assembly gap between the door and the white body with interior parts.

[0009] Therefore, there is an urgent need in the field for an adjusting device and method that can accurately simulate the actual weight state of the interior parts of the door in the white body stage, so that the door can be positioned in the "loaded" state when initially assembled, thereby fundamentally avoiding the subsequent gap variation and rework problems and improving the production rhythm and product quality.

[0051] Counterweight unit: The counterweight unit is the core of the device, which is used to accurately simulate the weight of the door interior.

[0052] The core carrier is a plug-in board 1, which is used to be inserted into the glass lifting groove of the door 102.

[0053] The counterweight unit further comprises a base counterweight unit 3 and a two-layer counterweight unit 4: The base counterweight unit 3 is fixed on the plug-in board 1 and comprises a first base block 31 and a second base block 32.

[0054] The first base block 31 and the second base block 32 are distributed on opposite sides of the plug-in board 1, and the three together constitute a stable T-shaped base structure; this structure not only provides a basic counterweight, but also the first and second base blocks 32 extending horizontally can act as a limiting piece to prevent the entire device from accidentally falling into the cavity of the door 102 during the adjustment of the door 102 The thickness of the first base block 31 is greater than that of the second base block 32, but the upper end faces of the two are arranged in the same plane.

[0055] This design is to adapt to the height difference between the inner plate and the outer plate of the door 102, to ensure that the device is installed flat and well matched with the inner and outer plates of the door 102.

[0056] The first base block 31 and the second base block 32 are preferably made of nylon material to avoid rigid collision with the sheet metal parts of the door 102 and cause scratches.

[0057] In order to further protect the door 102, a layer of rubber layer can be wrapped on the surface of the nylon block to realize flexible contact.

[0058] Second layer counterweight unit 4: in order to expand the application range of the device, so that it can adapt to different weight of the vehicle door 102, the second layer counterweight unit 4 is additionally arranged above the base layer counterweight unit 3.

[0059] The unit includes a first type of counterweight block 41 and a second type of counterweight block 42.

[0074] Step 4: detection and adjustment.

[0075] Observe the relative gaps of the vehicle door 102 around and the adjacent parts (such as the side wall).

[0076] If all the gaps are within the set qualified interval, it is determined that the installation position of the vehicle door 102 is qualified, and the adjusting device 101 is directly taken out.

[0077] If any gap is unqualified, the operator needs to adjust the hinge bolt of the vehicle door 102 on site to change the position of the vehicle door 102. Each adjustment is observed again until it is completely qualified, and then the adjusting device 101 is taken out.

[0078] Step 5: circulation and repetition. After the vehicle door 102 is adjusted, it is circulated to the next station. If other vehicle doors 102 need to be adjusted, steps 1 to 4 are repeated.
