[0002] In the field of automobile manufacturing, especially in the production process of light vehicles, the rotation and flipping of the side panel is a key step. The side panel is an important part of the vehicle's side structure, and its precise installation is crucial to the overall quality and safety of the vehicle.

[0003] In the existing technology, there are usually two ways to hoist and flip the inner panel of the side panel: one is to use hooks and chains, and the other is to use robots with grippers. Although the method of using hooks and chains is simple, it is easy to cause deformation of the inner panel of the side panel during the hoisting process, and it is impossible to flip it, which limits the subsequent gluing and other processes. In addition, there are safety hazards when workers operate under the hoisted workpiece. Although the method of using robots and grippers can achieve flipping, its high cost and difficulty in coordinating with manual operation lines also limit its application in production.

[0004] The existing lifting and flipping methods have the following technical problems:

[0005] 1. The hook and chain cannot realize the flipping of the inner panel of the side panel, which limits the subsequent process.

[0006] 2. The inner panel of the side panel may easily deform during the lifting process, affecting the quality and safety of the vehicle.

[0007] 3. There are safety hazards when workers operate under the hoisted workpiece.

[0029] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the art to which the present invention belongs. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0030] Example 1

[0031] In order to solve the technical problems of the background technology, this embodiment proposes a vehicle side inner panel clamping and flipping hanger, such as Figure 1 As shown, it mainly includes a frame structure 1, a hoisting mechanism 2 and a clamping mechanism 3. Figure 2 As shown, the frame structure 1 is composed of a connecting plate 11 and a hanging assembly on both sides. The hanging assembly includes a limit rod and a hanging rod to ensure the overall stability of the sling. Figure 3 As shown, the hoisting mechanism 2 includes a hoisting rod 22, the bottom of which is rotatably connected to the connecting plate 11, so that the hoist can be turned at an angle during operation. The fixing assembly includes a pressing block and a hook, which is abutted on the limit rod and hung on the hanging rod (such as Figure 4 , Figure 5 As shown in the figure), it provides a safe fixing method to prevent accidents during the lifting process. Figure 2As shown, the clamping mechanism 3 works together through the fixed clamping assembly 31, the transverse clamping assembly 32, the bidirectional clamping assembly 33 and the longitudinal clamping assembly 34, which are arranged in sequence around the frame structure 1, and can effectively clamp the side inner panels 5 of different sizes, ensuring their stability during the hoisting and flipping process, providing a good foundation for subsequent processes. The hoist improves the efficiency of the transfer of the side inner panels 5 of different wheelbase models on the same platform during the manufacturing process of light vehicles, and is convenient for flipping. It can achieve fast and accurate hoisting and flipping, making it convenient for workers to perform gluing operations, while eliminating safety hazards and improving production efficiency and product quality.

[0032] like Figure 3 , Figure 4 As shown, in this embodiment, a bent rod 26 is provided at the bottom of the suspension rod 22, and the bent rod 26 is bent toward the front side to increase the stability and flexibility of the suspension device. A rotating shaft 25 is provided at the bottom of the bent rod 26, and both ends of the rotating shaft 25 are installed in the bearing seat at the bottom of the connecting plate 11 of the frame structure 1, so that the suspension rod 22 can be flexibly rotated and meet the lifting requirements of various angles. This design not only enhances the carrying capacity of the suspension device, but also makes the clamping and flipping operations of the side inner plate 5 during the lifting process smoother, reduces the risk of damage caused by improper operation, and improves work efficiency.

[0033] The hanging assembly is located at the rear side of the connecting plate 11, the first hanging assembly 12 includes a horizontal first hanging rod 121 and a first limiting rod 122, and the fixing assembly includes a vertical fixing assembly 23, wherein the vertical fixing assembly 23 is composed of a vertical rod 231, a vertical hanging rod 232 and an opening pressing block 233. The vertical rod 231 is arranged at the rear side of the hanging rod 22, and the vertical hanging rod 232 is fixed at the rear side of the vertical rod 231, and its bottom is hung on the first hanging rod 121 (such as Figure 4 The opening block 233 is arranged obliquely, and its opening groove abuts against the first limit rod 122 to form an effective fixing point to prevent loosening due to vibration or gravity changes during the lifting operation, thereby ensuring the safety of the operation.

[0034] The hanging assembly also includes a second hanging assembly 13 located at the front side of the connecting plate 11, and the second hanging assembly 13 includes a horizontal second hanging rod 131 and a horizontal second limiting rod 132. The fixing assembly includes a horizontal fixing assembly 24, and the horizontal fixing assembly 24 is composed of a flat rod 243, a horizontal hook 241 and a flat pressing block 242. The flat rod 243 is located on both sides of the hanging rod 22 and is bent forward to enhance the stability of the structure. The horizontal hook 241 is installed on the flat rod 243, and its front side is hung on the second hanging rod 131 (such as Figure 5 As shown), the flat pressing block 242 abuts against the second limiting rod 132. This design ensures that all components can remain stable and do not fall off during the lifting process, ensuring the smooth progress of the lifting work.

[0035] The suspension rod 22 is an L-shaped rod with a U-shaped lifting ring 21 on the top. The L-shaped design provides a better support surface, so that the weight of the suspension rod 22 is reasonably distributed, thereby improving the overall stability. The U-shaped lifting ring 21 can be easily hung by lifting equipment such as an electric hoist, which is easy to operate and ensures the safety and efficiency of the lifting operation.

[0036] like Figure 2 , Figure 6 As shown, the fixed clamping assembly 31 is located at the left portion of the rear side of the frame structure 1, and the transverse clamping assembly 32 is located at the right end of the rear side of the frame structure 1 and can move left and right. The bidirectional clamping assembly 33 is located at the right end of the front side of the frame structure 1 and can move forward and backward and left and right, while the longitudinal clamping assembly 34 is located at the left end of the front side of the frame structure 1 and can move forward and backward. This structural arrangement can achieve a change in the position of the clamping block 35 by adjusting the positions of the transverse clamping assembly 32, the bidirectional clamping assembly 33 and the longitudinal clamping assembly 34 on the frame structure 1, thereby ensuring that the four clamping assemblies can effectively clamp the side inner panels 5 of vehicle models with different wheelbases. The layout design of the openings of the clamping blocks 35 relative to the holes of the side inner panels 5 enables all clamping blocks 35 to be snapped into the holes of the side inner panels 5 (such as Fig. 9 It provides a good clamping effect and ensures the stability and safety of the inner panel during lifting and flipping.

[0037] like Figure 7 As shown, the transverse clamping assembly 32 is composed of a first slide bar 321, a transverse rod 322 and a slider 323. The first slide bar 321 is installed on the frame structure 1 and arranged left and right, and its function is to provide a track for transverse sliding. The slider 323 is slidably installed on the first slide bar 321 to ensure the flexibility of the clamping operation. The transverse rod 322 is installed at the bottom of the slider 323, and a clamping block 35 is installed on the rear side thereof. This design allows the clamping block 35 to be adjusted according to the actual position of the side inner panel 5 during the clamping process, ensuring the accuracy and reliability of the clamping effect.

[0038] like Figure 7 , Figure 8As shown, the bidirectional clamping assembly 33 includes a second slide bar 331, a transverse plate 332, a slide plate 333, a push rod 334 and a handle 335. The second slide bar 331 is mounted on the frame structure 1 and arranged left and right, providing a sliding track for the slide plate 333. The slide plate 333 is slidably mounted on the second slide bar 331, the push rod 334 is slidably mounted on the slide plate 333 along the front and rear directions, and the handle 335 is mounted at the rear end of the push rod 334 for easy operation. The transverse plate 332 is mounted at the front end of the push rod 334 and connected to the clamping block 35. This structural design can realize the adjustment of the clamping block 35 in multiple directions, provide a more flexible clamping solution for the side inner panels 5 of different sizes, and improve the adaptability and efficiency of the operation. The longitudinal clamping assembly 34 is similar in structure to the bidirectional clamping assembly 33, the only difference is that the bidirectional clamping assembly 33 can move forward and backward and left and right relative to the frame structure 1, while the longitudinal clamping assembly 34 can only move forward and backward.

[0039] like Figure 6 As shown, in this embodiment, the clamping and flipping sling also includes a support mechanism 4, which is supported on the side inner panel 5 and includes a first support block 41, a second support block 42, a third support block 43 and a fourth support block 44. The first support block 41 and the second support block 42 are located at the rear side of the frame structure 1, and their bottoms are flat, providing a stable support surface. The third support block 43 and the fourth support block 44 are located at the front side of the frame structure 1. The bottom of the third support block 43 is a trapezoidal groove, which can adapt to different shapes of the side inner panel 5. The bottom of the fourth support block 44 is an L-shaped concave platform, which ensures effective support for the side inner panel 5 during the flipping operation. By cooperating with the four clamping components, it prevents tilting or falling off during the flipping process, thereby ensuring the safety and reliability of the overall operation.

[0040] The hoist is easy to operate, has low investment cost, is compatible with vehicles of different wheelbases on the same platform, has good safety performance, is durable, reusable, easy to hoist and flip, and facilitates manual gluing construction, thus improving production efficiency and product quality.

[0041] Example 2

[0042] This embodiment describes the working method of the sling in Example 1, including firstly keeping the frame structure 1 in a horizontal state (such as Figure 1 Next, the frame structure 1 is hoisted above the side panel inner plate 5, and the lateral clamping assembly 32, the bidirectional clamping assembly 33 and the longitudinal clamping assembly 34 are adjusted to match the holes of the side panel inner plate 5 and clamp the side panel inner plate 5 (as shown in FIG. Fig.10 Then, the side inner panel 5 is hoisted to the gluing station, and the frame structure 1 is rotated 90 degrees to a vertical state (as shown in FIG. Fig.11As shown), the side panel inner plate 5 is fixed by using the hanging assembly on the front side of the frame structure 1 and the fixing assembly on the front side of the lifting mechanism 2, and finally the gluing operation is completed on the side panel inner plate 5.

[0043] Specifically:

[0044] The electric hoist hook is hung into the U-shaped lifting ring 21, and after the open pressing block 233 is fitted with the steel main frame, the vertical hook 232 of the lifting device is matched with the first hanging rod 121 and hung tightly.

[0045] Use an electric hoist to hoist it above the side enclosure inner plate 5, adjust the transverse clamping assembly 32, the bidirectional clamping assembly 33 and the longitudinal clamping assembly 34, so that the clamping block 35 cooperates with the side enclosure hole, and the support block fits with the side enclosure inner plate 5.

[0046] The handle 335 is pulled to transmit force to the clamping block 35 through the push rod 334 , so that the clamping block 35 and the side inner panel 5 are completely clamped.

[0047] Lift the side inner panel 5 to the gluing station, open the vertical hook 232, and manually rotate the frame structure 1 90 degrees. The side inner panel 5 is clamped by the clamping block 35 and turns with the frame structure 1. After the flattening block 242 is attached to the frame structure 1, move the horizontal hook 241 to the second hanging rod 131.

[0048] Personnel can stand freely on the gluing side of the side inner panel 5 to carry out the gluing operation.

[0049] This working method ensures the stability and safety of the spreader during the entire operation process, providing good protection for the subsequent gluing process.

[0050] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
