Description

Technical Field

[0001] This utility model belongs to the field of metal surface treatment fixture technology, specifically relating to a universal fixture for chemical passivation of automobile door sill beams. Background Technology

[0002] Because of the length of car door sill beams, current technology cannot hang them vertically on the hanger during chemical passivation treatment. Instead, two operators must simultaneously lift the door sill beam and hang it horizontally on the hanger. This method of hanging presents at least two significant problems:

[0003] 1. Poor passivation effect

[0004] Uneven wetting: When aluminum car door sill beams are hung in a horizontal position, the passivation solution is difficult to evenly cover the entire surface and cavity. Especially for door sill beams with more complex internal structures, the passivation solution may not be able to fully penetrate the internal space, resulting in poor film formation.

[0005] Liquid residue: After the process is completed, passivation liquid may remain inside the horizontally placed threshold beam. This residual liquid is not easy to drain, which may lead to inconsistent film thickness and affect the quality of the final product.

[0006] Unstable processing: The product's position is unstable during processing, and it may move or tilt slightly, further exacerbating the unevenness of the passivation effect.

[0007] 2. Unreasonable spatial layout

[0008] Limited number of products that can be hung: Because sufficient lateral space needs to be left for each sill beam, the number of products that a single hanger can carry is very limited, which greatly restricts the space utilization of the production line.

[0009] Low processing efficiency: Only a small number of products can be processed at a time, which increases the processing cycle and reduces the overall production efficiency;

[0010] Resource waste: The space on the hanger is not fully utilized, which reduces the efficiency of the passivation solution and causes unnecessary waste of chemicals;

[0011] High labor intensity: It requires two operators to complete the hanging operation, which not only increases labor costs but also increases the intensity of work. In particular, fatigue is easily caused during long-term operation, which in turn affects the safety of operation and product quality.

[0012] In summary, the existing hanging method not only seriously affects the effect of chemical passivation treatment, but also results in an unreasonable spatial layout, reduces production efficiency, increases resource waste, and brings additional workload to operators. Utility Model Content

[0013] This utility model addresses the aforementioned problems in the existing technology by proposing a universal mounting bracket for chemical passivation of automotive door sill beams that increases the amount of material attached, improves the passivation effect, increases line utilization, and saves costs.

[0014] This utility model can be achieved through the following technical solutions:

[0024] As a further improvement of this utility model, the single set of lower positioning components consists of at least two lower positioning shafts.

[0025] As a further improvement of this utility model, the upper positioning shaft and the lower positioning shaft used to hang the same product are located on the same inclined straight line.

[0026] As a further improvement of this utility model, the upper positioning shaft and the lower positioning shaft are respectively inserted into the through holes at the upper and lower ends of the product to form a lock hole positioning structure.

[0027] As a further improvement of this utility model, the outer surfaces of both the upper positioning shaft and the lower positioning shaft are coated with adhesive.

[0028] As a further improvement of this utility model, the hanging frame is also provided with a reinforcing beam, which is connected to the top and bottom edges of the hanging frame and located near the middle of the hanging frame.

Increase the number of products that can be hung: The tilted hanging method reduces the space occupied by each product, so more products can be hung on the same rack, which significantly increases the number of products processed at one time and enhances the space utilization of the production line.

[0036] 6. Product protection: The outer surfaces of both the upper and lower positioning shafts 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

[0044] 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.

[0045] like Figure 1-3 As shown, this utility model provides a universal mounting bracket for chemical passivation of automobile door sill beams, comprising:

[0046] Hanging frame 100;

[0047] The product 400 hanging assembly is formed by combining the upper hanging rod 200 and the lower hanging rod 300 and is used to hang the product 400. Multiple sets of the product 400 hanging assembly are provided on the hanging frame 100.

[0048] The upper hanging rod 200 and the lower hanging rod 300 are respectively set on the top and bottom edges of the hanging frame 100;

[0049] The line connecting the upper hanging rod 200 and the lower hanging rod 300 of the same product 400 hanging assembly is an oblique line, and its tilt angle with the vertical line is between 20° and 30°. That is, the product 400 is hung at an angle, and the tilt angle of the product 400 after hanging is between 20° and 30°.

[0050] This tilted hanging method has at least the following advantages:

[0051] 1. Improve passivation effect

[0052] Uniform wetting: By hanging the product 400 at an angle of 20°-30°, it is ensured that the passivation solution can fully and evenly cover the surface and inner cavity of the aluminum automotive door sill beam. This tilted design facilitates the smooth flow of liquid into the internal structure of the product 400 and the rapid drainage of residual liquid after treatment, ensuring the uniformity of the film weight on the inner and outer cavity surfaces of the product 400.

[0053] 2. Optimize spatial layout

[0054] Increase the number of products that can be hung: The tilted hanging method reduces the space occupied by each product 400, so more products 400 can be hung on the same hanger, which significantly increases the number of products 400 processed at one time and enhances the space utilization of the production line.

[0055] Improved production line efficiency: By increasing the number of products processed per batch by 400, overall production efficiency was improved, and the processing time and cost per unit of 400 products were reduced.

[0056] Reduced labor intensity: The improved hanger design simplifies the hanging operation, requiring only one operator to hang the product 400, reducing manpower requirements, lowering labor intensity, and improving operational safety.

[0057] 3. Conserve resources

[0058] Reduced passivation solution waste: The optimized rack design ensures efficient use of passivation solution, reducing unnecessary chemical waste and meeting environmental protection and energy conservation requirements.

[0059] In summary, the hanger provided in this embodiment, through its unique structural design and reasonable layout, not only solves the problems existing in the prior art, but also doubles the hanging capacity, doubles the efficiency, doubles the cycle time, and increases the line utilization rate by 50% in practical applications, thus meeting the characteristics of high efficiency, energy saving, environmental protection, and low cost.

[0060] In addition, the hanger is made of stainless steel, which not only enhances its durability and corrosion resistance, but also extends its service life and reduces maintenance costs.

[0061] Preferably, both the front and back sides of the hanging frame 100 are product 400 hanging surfaces and have product 400 hanging components, which further improves the space utilization of the hanging frame 100.

[0062] Preferably, the upper hanging rod 200 is provided with an upper positioning member 210, and the number of upper positioning members 210 is provided in two sets and located on the front and rear product 400 hanging surfaces of the hanging frame 100 respectively;

[0063] The lower hanging rod 300 is provided with a lower positioning component 310. There are two sets of lower positioning components 310, which are located on the front and rear product 400 hanging surfaces of the hanging frame 100, thereby meeting the requirement of hanging the product 400 on both sides of the hanging frame 100.

[0064] The single upper positioning component 210 consists of at least two upper positioning shafts 211, and the single lower positioning component 310 consists of at least two lower positioning shafts 311. The upper positioning shafts 211 and lower positioning shafts 311 are respectively inserted into the through holes at the upper and lower ends of the product 400 to form a locking hole positioning structure, which prevents the product 400 from sliding or shifting position during the processing, ensures the stability of the passivation process, and improves the quality of the final product 400.

[0065] Furthermore, the upper positioning shaft 211 and the lower positioning shaft 311 used to hang the same product 400 are located on the same inclined straight line, so that the tilt angle of the product 400 after hanging is maintained between 20° and 30°. This design ensures that the posture of the product 400 is consistent throughout the entire processing, so that the passivation liquid can evenly cover the surface of the product 400, improving the uniformity of the film formation effect. At the same time, it simplifies the hanging operation, requiring only a single operator to complete the hanging operation of the product 400, reducing operation time and difficulty.

[0066] Preferably, the outer surfaces of the upper positioning shaft 211 and the lower positioning shaft 311 are coated with rubber to avoid the risk of bumps and scratches caused by direct contact between the product 400 and the stainless steel, while ensuring that the friction between the product 400 and the stainless steel hanging frame 100 is increased to ensure that the product will not slip.

[0067] Preferably, the hanging frame 100 is also provided with a reinforcing beam 110. The reinforcing beam 110 is connected to the top and bottom edges of the hanging frame 100 and is located near the middle of the hanging frame 100. This can better balance the stress distribution of the entire hanger, enhance the overall rigidity of the hanging frame 100, and prevent deformation under long-term use or heavy load.

[0068] Preferably, the top of the hanging frame 100 is also provided with a suspension rod 120 for connecting with the external target beam. The top of the suspension rod 120 is provided with a square hook 121. The square hook 121 can better match the shape of the target beam, ensuring a tight fit between the two and reducing gaps and looseness caused by shape mismatch. Compared with the traditional round hook, it significantly reduces the swaying amplitude of the hanging frame 100 during the process, provides more stable support, and prevents chemical waste or product damage caused by swaying.

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.
