DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

Therefore, they cannot be understood as limitations on the present invention.

[0034] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; and direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0035] Example 1:

[0036] like Figure 1 and Figure 2As shown, the utility model provides a side wall panel bonding auxiliary device, which is used to bond and fix the side wall panel 1 to the side wall frame 2 by applying glue. The side wall frame 2 is made of horizontal beams and longitudinal beams spliced ​​and welded. The side wall panels 1 are also multiple pieces laid flat on the side wall frame 2. The side wall panels 1 are bonded in sequence from bottom to top during bonding.

[0037] In this embodiment, the side wall panel bonding auxiliary device includes a magnetic adsorption component 3, a positioning line 4, a leveling pad 5 and a gap spacer 6.

[0038] At least two magnetic adsorption members 3 are fixed to the side wall frame 2 on either side of the side wall panel 1. The ends of the positioning line 4 are fixed to the two magnetic adsorption members 3. After installation, the positioning line 4 spans above the side wall panel 1. Depending on the length of the side wall frame 2, the length of the positioning line 4 can be selected to be 80m. In this embodiment, the magnetic adsorption members 3 are connected to the side wall frame 2 to facilitate the operator's removal and movement of the fixed position of the side wall frame 2, thereby moving the positioning line 4.

[0039] In this embodiment, it is more preferred to fix the two magnetic adsorption parts 3 on the side surface 2a perpendicular to the side wall frame 2 and the side wall panel 1. This not only tightens the positioning line 4, but also avoids the entire surface of the side wall frame 2 for bonding the side wall panel 1, making it convenient to install the leveling pad 5 on the side wall frame 2.

[0040] In this embodiment, the magnetic attachment 3 preferably includes a magnetic base 31 and hooks 32. The base 31 is attached to the side of the sidewall frame 2, and the ends of the positioning wire 4 are fixed to the hooks 32 on either side, ensuring that the positioning wire 4 can be straightened and tightened after installation. The structure of the base 31 and hooks 32 of the magnetic attachment 3 not only increases the attachment area between the magnetic attachment 3 and the sidewall frame 2, ensuring stable and secure fixation, but also facilitates connection with the positioning wire 3. The vertical suction force of the magnetic attachment 3 is preferably not less than 20 kg.

[0041] The side wall frame 2 is made of longitudinal beams and transverse beams spliced ​​and welded together. The welding deformation is particularly large at the intersecting locations. Therefore, in this embodiment, it is preferred to set the positioning line 4 at the intersecting locations of the side wall frame 2, that is, the positioning line 4 is pulled at each row of positions with intersecting points for positioning. After one position measurement is completed, the magnetic adsorption component 3 is removed from the side wall frame 2 and moved to the next row of positions with intersecting points, and the positioning line 4 is re-fixed and tightened. The measurement is then repeated, and this process is repeated until all intersecting points are measured. In this embodiment, the positioning line 4 is preferably made of a nylon thin wire with a diameter of 0.4mm to 0.6mm, and can withstand a maximum tensile force of not less than 10Kg.

[0042] The side wall frame 2 deforms after welding, with some parts convex and some concave. In this embodiment, multiple leveling pads 5 are installed on the side wall frame 2 to support the positioning wire 4 and adjust the distance between the positioning wire 4 and the side wall frame 2. In this embodiment, it is further preferred that multiple leveling pads 5 are installed on both sides of the side wall frame 2 near the edge. When the positioning wire 4 is in a taut state, it is closely attached to the top of the leveling pads 5. At this time, the thickness of the leveling pads 5 determines the distance between the positioning wire 4 and the surface of the side wall frame 2.

[0043] In this embodiment, in order to ensure the structural strength of the side wall panel 1 and the side wall frame 2 after bonding, the thickness of the glue layer between the side wall panel 1 and the side wall frame 2 is preferably not less than 3 mm. It is further preferred that the standard thickness of the glue layer is 3 mm, that is, it is necessary to ensure that there is at least a 3 mm gap between the highest point of the upward protrusion of the side wall frame 2 after deformation and the side wall panel 1 for applying sealant.

[0044] After tightening the positioning line 4, the operator measures along the positioning line 4, measuring the distance between the positioning line 4 and the side wall frame 2 and recording it. If the distance between the positioning line 4 and the highest point of the upward protrusion of the side wall frame 2 is less than the standard thickness of 3mm, the thickness of the leveling pad 5 is thickened to raise the positioning line 4 so that the distance between the positioning line 4 and the highest point of the upward protrusion of the side wall frame 2 meets the standard thickness requirement of the glue layer. At this time, the thickness of the leveling pad 5 is the thickness required for installing the side wall panel 1. In this way, when gluing the side wall panel 1, the side wall panel 1 can be directly placed on top of the leveling pad 5, thereby ensuring that the minimum distance between the side wall panel 1 and the side wall frame 2 is also guaranteed to be 3mm. After gluing, the leveling pad 5 is embedded in the glue layer and does not need to be removed.

[0045] In this embodiment, at least three leveling pads 5 are installed on either side of the side wall frame 2 to ensure that the overall flatness of the side wall panel 1 after bonding meets vehicle manufacturing requirements. Preferably, the leveling pads 5 are rubber pads, which provide support without damaging the side wall panel 1.

[0046] like Figure 2 As shown, in this embodiment, the gap spacer 6 is used to be inserted into the gap between two adjacent side wall panels 1. The thickness of the gap spacer 6 is the standard spacing of the gap. Multiple gap spacers 6 of the same specification can be inserted into the gap between two adjacent side wall panels 1 to ensure that the gap is uniform.

[0047] Specifically, the side wall panels 1 are bonded from bottom to top. After the lower side wall panel 11 is bonded, when the upper side wall panel 12 is bonded, multiple gap spacers 6 of appropriate thickness are used to support the upper side wall panel 12, ensuring a uniform gap between the lower and upper side wall panels 11, 12. The same gap spacers 6 can also be used when assembling the left and right side wall panels 1. Multiple gap spacers 6 are placed between the left and right side wall panels 1 to ensure a uniform gap between the left and right side wall panels 1.

[0048] like Figure 3 and Figure 4 As shown, in this embodiment, it is further preferred that the gap spacer 6 adopts a T-shaped structure, including a first portion 61 and a second portion 62 perpendicular to each other. The first portion 61 has a standard thickness and is used to be inserted into the gap between two adjacent side wall panels 1. The second portion 62 is used to fit the surface of the side wall panel 1 after insertion, ensuring that the gap spacer 6 can be stably fixed on the side wall panel 1 and ensuring uniform and consistent flashing. It is further preferred that the second portion 62 extends vertically outward from one side surface of the first portion 61. In this way, after installation, the second portion 62 fits the surface of the lower side wall panel 11, a portion of the second portion 62 is inserted into the gap, and the other portion not inserted into the gap is exposed on the outside of the side wall panel 1, which can facilitate the operator to take the gap spacer 6.

[0049] Regarding the gap spacer 6, this embodiment provides another implementation method. The gap spacer 6 can also adopt an L-shaped structure, which also includes a first part 61 and a second part 62 that are perpendicular to each other. The first part 61 has a standard thickness and is used to be inserted into the gap between two adjacent side wall panels 1. The second part 62 is used to fit the surface of the side wall panel 1 after insertion.

[0050] In this embodiment, the gap spacer 6 is preferably made of nylon material to ensure that the gap spacer 6 has sufficient strength while not damaging the side wall panel 1. The gap spacer 6 can be an integral structure, but in this embodiment, it is more preferably a split structure, with two countersunk threaded holes 63 on the first part 61, which is fixed to the second part 62 by two countersunk screws 64.

[0051] like Figure 1 and Figure 2 As shown, the process of bonding the side wall panels using the auxiliary device is described in detail below:

[0052] 1. Before bonding the lower side wall panel 11 , first tie the two ends of the positioning line 4 to the hooks 32 of the magnetic adsorption members 3 at both ends.

[0053] 2. Firmly adsorb the chassis 31 of the magnetic adsorption component 3 on the two side surfaces of the side wall frame 2, and tighten and straighten the positioning line 4. The positioning line 4 is located above the intersection of the longitudinal beam and the transverse beam of the side wall frame 2.

[0054] 3. Measure the distance between the side wall frame 2 and the positioning line 4, and record it to determine whether the distance is less than 3mm.

[0055] 4. If the spacing is less than 3 mm, increase the number of leveling pads 5 or replace the leveling pads 5 with different thicknesses to ensure that the minimum spacing between the side wall frame 2 and the positioning line 4 is 3 mm.

[0056] 5. Place the lower side wall panel 11 on the leveling pad 5, and then glue the lower side wall panel 11.

[0057] 6. After the lower side wall panel 11 is bonded to the side wall frame 2, select multiple gap spacers 6 with appropriate thickness and install the multiple gap spacers 6 between the adjacent lower side wall panels 11 and the upper side wall panels 12, so that the upper side wall panels 12 are padded on the multiple gap spacers 6, thereby ensuring that the flashing between the two adjacent side wall panels 1 is uniform.

[0058] 7. Repeat the above steps to bond all side wall panels 1 in sequence.

[0059] The side wall panel bonding auxiliary device provided by the utility model has the following beneficial effects:

[0060] 1. The device has a simple and reasonable structure, is efficient and convenient to use, can greatly improve the efficiency of side wall panel installation, and can be applied to the installation of side wall panels in different models and various occasions.

[0061] 2. This device facilitates the measurement and leveling of the flatness of the side wall frame before bonding the side wall panels, ensuring that the overall flatness of the installed side wall panels meets the vehicle design requirements. It also facilitates the adjustment of the gaps between adjacent side wall panels, ensuring that the gaps between the side wall panels are uniform and consistent, thereby ensuring the quality of the side wall panel installation.

[0062] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments with equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
