Description

Technical Field

[0001] The present application relates to the technical field of automotive component painting, and particularly relates to a hanger for electrophoretic painting of automotive parts. Background Art

[0002] In the process of electrophoretic painting of automotive parts, the hanger is an indispensable auxiliary tool for hanging and fixing the parts to be painted, ensuring that they can uniformly and stably receive the paint during the electrophoretic painting process.

[0003] Currently, most of the existing hangers for automotive bumper reinforcement crossbeams adopt a single-row hanger design and are often fixed only through the upper hanging points. Although this hanger is convenient to operate, in actual use, the loading capacity of the single-row hanger is limited and cannot meet the requirements of large-scale production. With the increase in the production volume of automobiles, the efficiency requirements for electrophoretic painting processing are also getting higher and higher. However, the existing single-row hangers have a small loading capacity, which limits the throughput of the production line and affects the overall production efficiency.

[0004] Secondly, the method of fixing through the upper hanging points easily causes the lower part of the bumper reinforcement crossbeam to shake. During the electrophoretic painting process, the parts need to be in a stable state to ensure that the paint can uniformly cover their surfaces. However, due to the method of fixing through the upper hanging points, the lower part of the parts cannot be effectively supported and limited, resulting in the parts being prone to shaking during the painting process. This not only affects the uniformity of the paint but also may cause collisions and damages between the parts.

[0005] In view of the above problems, a hanger for electrophoretic painting of automotive parts is now designed. Summary of the Utility Model

[0006] The embodiments of the present application provide a hanger for electrophoretic painting of automotive parts to solve the problems in the related art that most of the existing hangers for automotive bumper reinforcement crossbeams adopt a single-row hanger and the method of fixing through the upper hanging points, resulting in a small loading capacity and easy collision due to the shaking of the lower part of the bumper reinforcement crossbeam.

[0007] In a first aspect, a hanger for electrophoretic painting of automotive parts is provided, including:

[0008] A bracket, on which two upper fixing plates are oppositely arranged. A plurality of upper hooks are arranged at the bottom of the upper fixing plate, and the upper hooks are used to fix the top of the parts. Fixing plates are oppositely arranged on the bracket, and a limiting tooling is arranged on the side of the fixing plate away from the bracket, and the limiting tooling is used to limit the bottom end of the parts.

[0009] In some embodiments, the limiting tooling includes a support plate, a plurality of rubber strips, and an insertion strip. The support plate is arranged on the fixed plate. A front baffle is arranged at one end of the support plate, and a rear baffle is rotatably arranged at the other end of the support plate. The plurality of rubber strips are sequentially arranged on the support plate, the front baffle, and the rear baffle. The insertion strip is arranged on the front baffle.

[0010] In some embodiments, the rear baffle includes a rotating shaft rotatably arranged at the end of the fixed plate. A torsion spring is arranged outside the rotating shaft, and a retaining piece is arranged on the rotating shaft outside the torsion spring.

[0011] In some embodiments, a set of connecting hooks is arranged at the top of the bracket, and the connecting hooks are used to connect with an external conveying cableway.

[0012] In some embodiments, the fixed plate is located at the bottom of the upper fixed plate, and the upper hook and the corresponding limiting tooling are symmetrically arranged up and down.

[0013] In some embodiments, a plurality of through holes are formed in the fixed plate, and a set of reinforcing plates connected to the bracket are oppositely arranged on the fixed plate.

[0014] In some embodiments, the upper fixed plate includes a set of support rods and a mounting plate. The set of support rods are oppositely arranged above the bracket, the mounting plate is arranged between an adjacent set of the support rods, and the upper hook is arranged at the bottom of the mounting plate.

[0015] The embodiment of the present application provides a hanger for electrophoretic coating processing of automotive parts. By the combined use of the upper hook and the limiting tooling, the hanger can ensure the stability of automotive parts during the electrophoretic coating process, and avoid problems such as uneven coating or coating damage caused by the shaking or displacement of the parts. By using the bracket and the two upper fixed plates, double-sided hanging points can be adopted to increase the hanging capacity and improve the production efficiency.

[0016] The hanger is reasonably designed and easy to operate. The staff only needs to fix the top and bottom of the parts at the corresponding positions of the hanger respectively, without a complex operation process, which improves the work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0025] The embodiment of the present application provides a hanger for electrophoretic coating processing of automotive parts, which can solve the problems in the related art that the existing hangers for automotive bumper reinforcement crossbeams mostly adopt a single-row hanger and a fixed upper hanging point method, resulting in a small hanging capacity and easy collision due to the shaking of the lower part of the bumper reinforcement crossbeam.

[0026] Please refer to Figures 1 - 3 , a hanger for electrophoretic coating processing of automotive parts includes; a bracket 1, two upper fixed plates 2 are oppositely arranged on the bracket 1, a plurality of upper hooks 3 are arranged at the bottom of the upper fixed plate 2, the upper hooks 3 are used to fix the top end of the parts, a fixed plate 4 is oppositely arranged on the bracket 1, and a limit tooling 5 is arranged on the side of the fixed plate 4 away from the bracket 1, and the limit tooling 5 is used to limit the bottom end of the parts.

[0027] Specifically, the fixture includes a bracket 1, on which two upper fixed plates 2 are oppositely arranged. At the bottom of these two upper fixed plates 2, there are multiple upper hooks 3, which are used to fix the top of the automotive parts. At the same time, a fixed plate 4 is also arranged on the bracket 1, and a limiting tooling 5 is arranged on the side of the fixed plate away from the bracket. The function of the limiting tooling is to limit the bottom position of the automotive parts to ensure the stability of the parts during the electrophoretic coating process.

[0028] During the electrophoretic coating process, the staff first fix the top of the automotive parts on the fixture through the upper hooks 3, and then use the limiting tooling 5 to limit the bottom of the parts to ensure that the parts are in the correct position and posture in the electrophoretic tank. After that, the fixture enters the electrophoretic tank along the assembly line for electrophoretic coating operation.

[0029] In actual use, through the combined use of the upper hooks 3 and the limiting tooling 5, this fixture can ensure the stability of the automotive parts during the electrophoretic coating process, avoid problems such as uneven coating or coating damage caused by the shaking or displacement of the parts, and the use of double-sided hanging points can increase the hanging capacity and improve production efficiency.

[0030] This fixture is reasonably designed and easy to operate. The staff only need to fix the top and bottom of the parts at the corresponding positions of the fixture respectively, without a complex operation process, which improves work efficiency.

[0031] Since this fixture adopts a modular design, the positions and quantities of the upper fixed plates 2 and the fixed plate 4 can be adjusted according to needs, so it can adapt to the electrophoretic coating requirements of automotive parts with different sizes and shapes.

[0032] By ensuring the stability of the parts during the electrophoretic coating process, this fixture helps to improve the uniformity and adhesion of the coating, thus enhancing the coating quality.

[0033] Preferably, in this embodiment, the limiting tooling 5 includes a support plate 51, several rubber strips 52, and an insertion strip 53. The support plate 51 is arranged on the fixed plate 4. One end of the support plate 51 is provided with a front baffle 54, and the other end of the support plate 51 is rotatably provided with a rear baffle 55. Several rubber strips 52 are sequentially arranged on the support plate 51, the front baffle 54, and the rear baffle 55. The insertion strip 53 is arranged on the front baffle 54.

[0034] The limiting tooling 5 is used to fix the bottom of the automotive parts and ensure its stability.

[0035] The support plate 51 is the main part of the limiting tooling 5, which is installed on the fixed plate 4 to provide a basic support surface for the parts.

[0036] The rubber strips 52 are sequentially arranged on the support plate 51, the front baffle 54 and the rear baffle 55. These rubber strips 52 not only increase the contact area with the components, improve the friction force, and prevent the components from sliding during the electrophoretic coating process, but also their soft material can effectively avoid damage to the components caused by direct collision.

[0037] The front baffle 54 is arranged at one end of the support plate 51, and its main function is to prevent the components from sliding forward or tipping over during the electrophoretic coating process. The inserted bar 53 arranged on the front baffle 54 cooperates with the assembly hole of the automobile bumper reinforcement beam and can be used for further fixation to increase its stability.

[0038] The rear baffle 55 is rotatably arranged at the other end of the support plate 51. By adjusting the angle of the rear baffle 55, components of different sizes and shapes can be adapted to achieve a better limiting effect.

[0039] In summary, in actual use, by adjusting the angle of the rear baffle 55, the limiting tooling 5 can adapt to components of different sizes and shapes, improving the versatility and flexibility of the hanger.

[0040] The addition of the rubber strips 52 increases the friction force with the components, effectively preventing the components from sliding or tipping over during the electrophoretic coating process and improving the stability and quality of the coating.

[0041] The soft material of the rubber strips 52 can avoid direct collision between the components and the limiting tooling 5, reducing the risk of component damage.

[0042] As Figure 5 shown, specifically, as a preferred embodiment, the rear baffle 55 in this implementation scheme includes a rotating shaft 551 rotatably arranged at the end of the fixing plate 4. A torsion spring 552 is arranged outside the rotating shaft 551, and a retaining piece 553 located outside the torsion spring 552 is arranged on the rotating shaft 551.

[0043] The rear baffle 55 lies in its rotatability and automatic reset function.

[0044] The rotating shaft 551 is a connecting piece between the rear baffle 55 and the fixing plate 4, allowing the rear baffle 55 to rotate relative to the fixing plate 4 by a certain angle. This rotational design enables the rear baffle 55 to flexibly adapt to components of different sizes and shapes, thus ensuring the stable fixation of the components.

[0045] The torsion spring 552 is installed outside the rotating shaft 551. When the rear baffle 55 is rotated to adapt to the components, the torsion spring 552 will be compressed or stretched. The elastic force of the torsion spring 552 provides the rear baffle 55 with an automatic reset function, that is, when there is no external force, the rear baffle 55 will automatically return to its initial position under the elastic force of the torsion spring 552.

[0046] As Figure 4 shown, specifically, a set of connecting hooks 6 are provided at the top of the bracket 1 in this implementation scheme, and the connecting hooks 6 are used to connect with an external conveying cableway.

[0047] In this implementation scheme, a set of connecting hooks 6 are provided at the top of the bracket 1 of the hanger. The main function of these connecting hooks 6 is to connect with an external conveying cableway. This design is to meet the requirements of the electrophoretic coating processing production line, enabling the hanger to be conveniently and stably mounted on the conveying cableway, thereby realizing the automatic conveying and coating processing of parts.

[0048] When it is necessary to mount the hanger on the conveying cableway, the staff only needs to dock the connecting hook 6 with the corresponding connection point of the external conveying cableway.

[0049] The design of the connecting hook 6 should ensure that it can be firmly fixed on the conveying cableway to prevent falling off or shaking during the conveying process, thereby ensuring the stability and safety of the parts.

[0050] Specifically, the fixed plate 4 in this implementation scheme is located at the bottom of the upper fixed plate 2, and the upper hook 3 and the corresponding limiting tooling 5 are symmetrically arranged up and down.

[0051] The fixed plate 4 is located at the bottom of the upper fixed plate 2. This design is to better support and fix the parts. More particularly, the upper hook 3 and the corresponding limiting tooling 5 are arranged symmetrically up and down.

[0052] In this implementation scheme, a number of through holes are provided on the fixed plate 4, and a set of reinforcing plates 7 connected to the bracket 1 are oppositely arranged on the fixed plate 4.

[0053] A number of through holes are provided on the fixed plate 4. The specific number, size, and position of these through holes may vary according to the actual application and the size and shape of the parts.

[0054] The main function of the through holes is to allow the electrophoretic solution or related fluids to pass through during the coating process, ensuring that the parts can uniformly and fully contact the electrophoretic solution, thereby obtaining a high-quality coating.

[0055] Through a reasonable design of the through holes, the accumulation and retention of the electrophoretic solution can also be reduced, which helps to maintain the cleanliness and stability of the electrophoretic tank.

[0056] The main function of the reinforcing plate 7 is to increase the connection strength between the fixed plate 4 and the bracket 1, improving the structural stability and load-bearing capacity of the entire hanger.

[0057] As Figure 4As shown, furthermore, in this embodiment, the upper fixed plate 2 includes a group of support rods 21 and a mounting plate 22. A group of support rods 21 are oppositely arranged above the bracket 1, the mounting plate 22 is arranged between an adjacent group of the support rods 21, and the upper hook 3 is arranged at the bottom of the mounting plate 22.

[0058] The main function of the support rod 21 is to provide structural support for the upper fixed plate 2 to ensure its stability and load-bearing capacity during the entire electrophoretic coating process.

[0059] The mounting plate 22 is arranged between an adjacent group of support rods 21 and serves as the mounting base for the upper hook 3.

[0060] The material of the mounting plate 22 should have a certain strength and stiffness to ensure that it can firmly support the upper hook 3 and the mounted components.

[0061] The upper hook 3 is arranged at the bottom of the mounting plate 22 and is used to hang the top of automotive components.

[0062] The design of the upper hook 3 should consider its shape, size and load-bearing capacity to ensure that it can firmly fix the components and withstand various forces and torques during the electrophoretic coating process.

[0063] Through the combination of the support rod 21 and the mounting plate 22, the upper fixed plate 2 can effectively support and fix the upper hook 3 and the components mounted thereon.
