Description

Technical Field

[0001] This utility model relates to the field of coating technology in automotive parts manufacturing, specifically a magnetic sealing hanger. Background Technology

[0002] Among automotive parts, some parts need to be assembled with other parts and cannot be painted, while other parts need to be painted. Currently, for painting such parts, it is necessary to apply glue or a film to the non-painted surface. After painting, cleaning the non-painted surface is time-consuming and laborious, and incomplete cleaning will affect the assembly accuracy of the parts.

[0003] To address the aforementioned issues, a Chinese utility model patent application with application number 2025001660908, entitled "A Threaded Sealing Fixture," proposed a technical solution. This solution involves inserting the unpainted surface of a component into the cylinder of the fixture, then screwing the bolts at the top of the unpainted surface into the fixture to seal the unpainted surface. However, this method requires tightening the bolts between the component and the fixture for painting, and then unscrewing the component after painting. This is time-consuming and labor-intensive for operators, and results in low production efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a magnetic sealing hanger that can effectively solve the problems of low cleaning efficiency of parts on non-painted surfaces, incomplete cleaning affecting the assembly accuracy of parts, time-consuming and labor-intensive operation, and low production efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a magnetic sealing hanger, including a hanger frame, a hook at the upper end of the hanger frame, and two hanging cylinders symmetrically fixedly connected at the lower end of the hanger frame. The bottom of the hanging cylinder is sealed, and a gasket is connected to the top opening. A magnetic ring is closely attached to the lower part of the gasket and is magnetically attracted to a recessed platform on the inner wall of the top of the hanging cylinder. A spring support is provided inside the hanging cylinder, and the lower end of the spring support contacts the bottom of the hanging cylinder. The hanger frame, spring support, and hanging cylinder are all made of metal.

[0006] Further improvements include: both the hanging bracket and the hanging cylinder are made of Q235 steel.

[0007] A further improvement is that the bracket and the hanging cylinder are fixedly connected by welding.

[0008] A further improvement is that the gasket is made of silicone.

[0009] A further improvement is that the top of the spring support is a circular metal plate, and a metal spring is fixedly connected to its lower part.

[0010] A further improvement is that the magnetic sealing hanger is used for electrophoretic coating.

[0011] The beneficial effects of this utility model are as follows: The use of this new magnetic sealing hanger can effectively improve the cleaning efficiency of non-painted surfaces of parts, ensure the cleanliness of assembly contact surfaces of parts, and improve the assembly accuracy of parts. At the same time, it reduces the labor intensity of operators and improves production efficiency. Attached Figure Description

[0014] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0015] See Figures 1 to 3 As shown, this utility model embodiment provides a magnetic sealing hanger, including a hanger 1. The upper end of the hanger 1 is provided with a hook, and two hanging cylinders 5 are symmetrically fixedly connected to its lower end. The bottom of the hanging cylinder 5 is sealed, and a gasket 2 is connected to the top opening. A magnetic ring 3 is closely attached to the lower part of the gasket 2. The magnetic ring 3 is magnetically attracted to a recessed platform on the inner wall of the top of the hanging cylinder 5. A spring support 4 is provided inside the hanging cylinder 5, and the lower end of the spring support 4 contacts the bottom of the hanging cylinder 5. The hanger 1, the spring support 4, and the hanging cylinder 5 are all made of metal. In this embodiment, the hanger 1, spring support 4, and hanging cylinder 5 are all made of metal, which facilitates the connection between the painted parts 6 and the electrodes for electrophoretic coating.

[0016] See Figure 1 As shown, both the bracket 1 and the hanging cylinder 5 are made of Q235 steel.

[0017] See Figure 1 As shown, the bracket 1 and the hanging cylinder 5 are fixedly connected by welding. In this embodiment, there are various fixed connection methods, such as snap-fit, threaded connection, welding, etc. Welding is preferred because it is simple, convenient and low in cost.

[0018] See Figure 1As shown, the gasket 5 is made of silicone. In this embodiment, silicone has good elasticity, good sealing performance, oil resistance, and high temperature resistance.

[0019] See Figure 1 As shown, the top of the spring support 4 is a circular metal plate, and a metal spring is fixedly connected to its lower part.

[0020] See Figure 3 As shown, the magnetic sealing hanger described above is used for electrophoretic coating; the hanger in this embodiment is specifically designed for electrophoretic coating, which is currently the most mainstream and best rust-proof coating for automotive parts.

[0021] The working principle of this utility model is as follows: See Figures 1 to 3 As shown, first, the shaft of the paint part 6 is inserted into the hanging cylinder 5. Then, the gasket 2 at the opening of the hanging cylinder 5 is pressed tightly against the shoulder of the paint part 6, so that the magnetic ring 3 at the opening of the hanging cylinder 5 attracts the shoulder of the paint part 6 through magnetic force, thus sealing the inside of the hanging cylinder 5 and ensuring that the paint cannot enter the hanging cylinder 5. At the same time, the top of the shaft of the paint part 6 contacts the spring support 4 inside the hanging cylinder 5, ensuring that the electrophoresis electrode is connected to the paint part 6 through the magnetic sealing hanger. Finally, the magnetic sealing hanger with the paint part 6 installed is hung on the electrophoresis pool conveyor line for electrophoretic coating.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any simple modifications, equivalent substitutions, improvements, etc. made within the technical concept of the present utility model should be included within the protection scope of the present utility model.
