Description

Technical Field

[0001] This utility model belongs to the field of metal surface treatment hanger technology, specifically relating to a universal hanger for a U-shaped rear side panel of a car. Background Technology

[0002] To meet the requirements of modern industry, especially the automotive industry, for high-quality and long-life components, chemical passivation of automotive components is of particular importance. Chemical passivation can form a dense oxide film or other types of protective film on the metal surface, which can significantly improve the corrosion resistance of the product and extend its service life. This is especially important for automotive components exposed to complex environments.

[0003] During the chemical passivation process, the product needs to be hung on a fixture first, and then the passivation solution needs to be applied to the surface and inner cavity of the product. However, the fixtures currently used for aluminum automotive U-shaped rear side panels have the following problems:

[0004] 1. Due to the unreasonable spatial layout, the number of products hanging on the equipment is too small, and there is a risk that the products may slip during movement, posing a safety hazard to the workers and the equipment line.

[0005] 2. Due to design flaws in the mounting fixture, the passivation solution cannot evenly cover the product surface and inner cavity, resulting in poor passivation film formation and low film uniformity, while also causing serious waste of the passivation solution.

[0006] 3. High product cycle time, low line utilization, low production efficiency and increased production costs. Utility Model Content

[0007] This utility model addresses the aforementioned problems in the existing technology by proposing a universal mounting bracket for the U-shaped rear side panel of automobiles that increases the amount of hanging capacity, improves the passivation effect, increases the line utilization rate, and saves costs.

[0008] This utility model can be achieved through the following technical solutions:

[0009] A universal mounting bracket for a U-shaped rear side panel of a car, comprising:

[0010] Hanging frame;

[0011] The inner frame is detachably installed inside the hanging frame. The number of inner frames is set to be multiple and distributed at intervals. The inner frames are arranged in a grid structure and have several slots. The slots of the multiple inner frames are aligned vertically.

[0012] A base frame, which is detachably mounted on the bottom of the hanging frame;

[0013] The product is hung vertically inside the hanging frame, with its upper and lower ends passing through the slots and hanging on at least two of the inner frames, and its lower end abutting against the bottom frame.

[0014] As a further improvement of this utility model, a separating groove is provided between the left and right adjacent card slots, and the left and right adjacent products are separated by the separating groove.

[0015] As a further improvement of this utility model, the hanging frame is provided with multiple sets of positioning elements spaced apart along its longitudinal direction.

[0016] As a further improvement of this utility model, a set of the positioning components consists of multiple positioning pins located on the same horizontal plane.

[0017] As a further improvement of this utility model, hooks are provided on both sides of the inner frame and the bottom frame, and the hooks are hung on the positioning pins.

[0018] As a further improvement of this utility model, the bottom frame is arranged in a grid structure and has several abutment grooves, and the lower end of the product abuts against the abutment grooves.

[0019] As a further improvement of this utility model, the bottom frame abuts against the bottom plate frame of the hanging frame.

[0020] As a further improvement of this utility model, the inner frame and the bottom frame are covered with adhesive.

[0021] As a further improvement of this utility model, the top of the hanging frame is provided with a suspension rod for connecting with the external target beam. Both the upper and lower ends of the suspension rod are provided with square hooks, which are connected to the hanging frame and the target beam.

[0022] As a further improvement of this utility model, the middle part of the suspension rod has a bent portion and is configured as a reinforcing plate.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. Stable hanging: The product is hung vertically inside the hanging frame. The top and bottom ends of the product pass through the slots and are hung on at least two inner frames. Since the product is U-shaped, the contact point between the inner frame and the product will form the hanging point of the product. At the same time, the bottom end of the product rests against the bottom frame, thereby ensuring that the product is hung stably and reducing the risk of the product slipping.

[0025] 2. Increase the number of hanging items: By designing the inner frame slots and combining them with the vertical hanging method of the products, the space layout is optimized, the number of hanging items per unit area is increased, and the space utilization rate of the production line is improved.

[0026] 3. Improved passivation effect: The vertical hanging method also allows the passivation solution to cover the entire product surface and inner cavity more evenly. At the end of the chemical passivation treatment, the passivation solution remaining in the product cavity can be quickly discharged, which improves the quality and uniformity of the passivation film, while also reducing the waste of passivation solution and lowering the processing cost.

[0027] 4. Improve production line efficiency: By increasing the number of products processed each time, the overall production efficiency is improved, and the processing time and cost per unit product are reduced;

[0028] 5. Product protection: Both the inner and bottom frames are coated with rubber to avoid the risk of bumps and scratches caused by direct contact between the product and stainless steel. At the same time, it ensures increased friction between the product and the stainless steel hanging frame to prevent the product from slipping. Attached Figure Description

Detailed Implementation

[0032] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. The technical methods of the present invention will be further described, but the present invention is not limited to these embodiments.

[0033] like Figure 1-2 As shown, this utility model provides a universal mounting bracket for the U-shaped rear side panel of an automobile, comprising:

[0034] Hanging frame 100;

[0035] The inner frame 110 is detachably installed inside the hanging frame 100. Multiple inner frames 110 are provided and distributed at intervals. The inner frames 110 are arranged in a grid structure and have several slots 111. The slots 111 of the multiple inner frames 110 are aligned vertically.

[0036] The bottom frame 120 is detachably mounted on the bottom of the hanging frame 100;

[0037] Specifically, in this embodiment, the product 200 is vertically hung inside the hanging frame 100. The upper and lower ends of the product 200 pass through the slots 111 and are hung on at least two inner frames 110. Since the product 200 is U-shaped, the contact point between the inner frame 110 and the product 200 will form the hanging point of the product 200. At the same time, the lower end of the product 200 abuts against the bottom frame 120, thereby ensuring that the product 200 is stably hung and reducing the risk of the product 200 slipping.

[0038] Furthermore, the vertical hanging of product 200 optimizes the spatial layout, increases the number of products per unit area, and improves the space utilization of the production line. This vertical hanging method also allows the passivation solution to cover the entire surface and inner cavity of product 200 more evenly. At the end of the chemical passivation treatment, the passivation solution remaining in the inner cavity of product 200 can be quickly discharged, improving the quality and uniformity of the passivation film, while also reducing the waste of passivation solution and lowering the processing cost.

[0039] Preferably, a partition groove 112 is provided between the left and right adjacent slots 111. The left and right adjacent products 200 are separated by the partition groove 112. Because the product 200 has a U-shaped structure, the left and right adjacent products 200 need to maintain sufficient independent space through the partition groove 112 to avoid mutual interference between the products 200, further improve the uniformity of passivation liquid coverage, and make it easier to hang the product 200.

[0040] Preferably, the hanging frame 100 has multiple sets of positioning elements distributed at intervals along its longitudinal direction, and each set of positioning elements consists of multiple positioning pins 130 located on the same horizontal plane.

[0041] Meanwhile, hooks 140 are provided on both sides of the inner frame 110 and the bottom frame 120. The hooks 140 are hung on the positioning pins 130 to realize the installation of the inner frame 110 and the bottom frame 120. The design of the positioning pins 130 and hooks 140 allows the inner frame 110 and the bottom frame 120 to be quickly installed and disassembled, reducing assembly time and improving the flexibility of the production line. When adjustment or maintenance is required, the operation is simple and quick, without the need for complicated tools or procedures.

[0042] Preferably, the bottom frame 120 abuts against the bottom plate frame of the hanging frame 100, and the bottom frame 120 is arranged in a grid structure with several abutment grooves 121. The lower end of the product 200 abuts against the abutment grooves 121. The abutment grooves 121 ensure that each product 200 has a support point at its lower end. This not only prevents the product 200 from sliding or tilting during processing, but also greatly enhances the stability and reliability of the overall hanging fixture.

[0043] Preferably, the inner frame 110 and the bottom frame 120 are covered with adhesive. The adhesive layer can effectively buffer the direct contact between the product 200 and the hanger, avoiding scratches, dents and other damage caused by direct friction or collision of the metal surface. This is crucial for maintaining the appearance quality and surface integrity of the product 200.

[0044] In addition, the rubber coating material usually has a high coefficient of friction, which can enhance the friction between the product 200 and the hanger, reduce the risk of the product 200 sliding or shifting during the handling process, and thus improve the overall stability and reliability of the hanger.

[0045] Preferably, the top of the hanging frame 100 is provided with a suspension rod 150 for connecting with the external target beam. Both the upper and lower ends of the suspension rod 150 are provided with square hooks 151, which are connected to the hanging frame 100 and the target beam. The square hooks 151 can better match the shape of the hanging frame 100 and the target beam, ensuring a tight fit and reducing gaps and looseness caused by shape mismatch. Compared with the traditional round hooks 140, the swing amplitude of the hanging frame 100 during the process is significantly reduced, providing more stable support and preventing chemical waste or product 200 damage caused by shaking.

[0046] Preferably, the middle part of the suspension rod 150 has a bent portion and is configured as a reinforcing plate 152. The setting of the reinforcing plate 152 enhances the structural strength of the suspension rod 150, enabling it to withstand greater weight and stress. This not only improves the overall load-bearing capacity of the hanger, but also ensures that the suspension rod 150 will not deform or break even under long-term use or heavy load conditions.

[0047] In addition, the entire frame 100 is made of stainless steel, which not only enhances its durability and corrosion resistance, but also extends its service life and reduces maintenance costs.

The above are specific embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.

[0049] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure).
