Description

Technical Field

[0001] This utility model relates to the field of automotive lighting processing technology, specifically to an aluminum plating fixture for aluminum plating on the surface of vehicle headlight reflectors. Background Technology

[0002] Aluminum plating for automotive headlights is a surface treatment method that involves electroplating or other processes to coat the surface of the reflector with aluminum, giving it better wear resistance, corrosion resistance, and aesthetic appeal. To improve the aluminum plating effect, multiple reflectors to be plated are typically mounted using specialized hangers, allowing for simultaneous aluminum plating of multiple reflectors. Before aluminum plating, a primer is applied to the reflector surface to enhance the stability of the subsequent aluminum plating layer.

[0003] For example, Chinese patent document CN217203040U discloses an electroplating hanger, including several support columns and several strut shaft hanger mechanisms. Each strut shaft hanger mechanism includes two mounting rings and several hanging pins. The two mounting rings are vertically spaced apart, and the hanging pins are equidistantly arranged on the outer ring of the mounting rings. The support columns are arranged in a circle and are fixedly connected to the inner ring of the mounting rings.

[0004] In the above technical solution, by setting the hanging pin, after the support rod shaft core is inserted into the hanging pin, the hanging pin is released. Under the action of the metal elasticity of the hanging pin, the support rod shaft core is firmly inserted into the support rod shaft hanger mechanism, which ensures that it will not fall off during the electroplating process, and the electroplating layer is of uniform thickness and has consistent brightness on both sides.

[0005] However, in actual use, when the reflector is hung on the rack for primer spraying, because the spray gun is on the outside of the rack, only the outer surface of the reflector can be evenly sprayed. Thus, the reflector can only be hung back on the rack after the primer on the outer surface of the reflector has dried completely, so that the inner surface of the reflector is facing the spray gun to complete the primer spraying on the inner surface of the reflector. Therefore, the overall spraying time is long, which affects the efficiency of subsequent aluminizing processing. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an aluminum plating hanger for aluminum plating on the surface of vehicle headlight reflectors, which can complete the turning of the reflector without contacting the reflector, thereby improving the efficiency of painting the reflector.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an aluminum-plating hanger for aluminum plating on the surface of vehicle headlight reflectors, comprising a shaft, a connecting sleeve fixedly fitted around the outer periphery of the shaft, multiple connecting sleeves spaced apart from each other, a connecting plate on the outer side of the connecting sleeve, a support rod between the connecting plate and the connecting sleeve, one end of the support rod fixed to the inner side of the connecting plate, and the other end fixed to the outer side of the connecting sleeve, multiple support rods evenly distributed circumferentially, a connecting rod rotatably connected to the connecting plate in the vertical direction, the lower end of the connecting rod extending below the connecting plate as a connecting end, the connecting end connected to a fixing clamp, and a steering device above the connecting plate for driving each connecting rod to rotate.

[0008] The present invention is further configured such that: the steering device includes a drive ring, the connecting plate is provided with a guide groove, the bottom of the drive ring serves as a coupling end, the coupling end is adapted to the guide groove and can form a sliding fit between the two, the upper end of the connecting rod extends above the connecting plate as an extension end, the extension end is fitted with a transmission gear, the drive ring is provided with a transmission rack, the transmission rack can mesh with the transmission gear and form a transmission fit between the two.

[0009] The present invention is further configured such that an upwardly extending lever is fixed on the drive ring.

[0010] The present invention is further configured such that: a limiting cover plate is provided on the connecting plate, a first threaded hole is provided on the connecting plate, a second threaded hole corresponding to the first threaded hole is provided on the limiting cover plate, the limiting cover plate and the connecting plate are threadedly connected through the second threaded hole and the first threaded hole, and the limiting cover plate abuts against the surface of the drive ring to limit the drive ring axially.

[0011] The present invention is further configured such that: the connecting sleeve is provided with a through third threaded hole, and a tightening bolt is provided in the third threaded hole to form a threaded engagement with the third threaded hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Because a steering device is installed above the connecting plate, after the primer is applied to one side of the reflector held in place by the clamp, the steering device can rotate each connecting rod. This allows the reflector to be turned without contacting it, eliminating the need for the primer on one side of the reflector to dry completely before turning. This allows for direct application of primer to the other side of the reflector, reducing the time required to paint the entire reflector and improving the overall efficiency of the aluminum plating process.

[0017] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] like Figures 1 to 3 As shown, this utility model discloses an aluminum plating fixture for aluminum plating on the surface of vehicle headlight reflectors, including a shaft 1. The shaft 1 is configured to be fixed to a bushing inside an existing aluminum plating tank during aluminum plating. A connecting sleeve 2 is fixed to the outer periphery of the shaft 1. The connecting sleeves 2 are spaced apart along the direction of the shaft 1. A connecting plate 3 is provided on the outer side of each connecting sleeve 2. The connecting plate 3 and the connecting sleeve 2 are connected by a support rod 4. That is, one end of the support rod 4 is fixed to the inner side of the connecting plate 3 and the other end is fixed to the outer side of the connecting sleeve 2. There are multiple support rods 4 and they are evenly distributed around the outer periphery of the shaft 1. In this way, the connection plate 3 and the connecting sleeve 2 can be stably connected by the multiple support rods 4.

[0020] A connecting rod 5 is rotatably connected to the connecting plate 3 in a vertical direction. The connecting rod 5 is rotatably connected to the connecting plate 3 through a bearing. The lower end of the connecting rod 5 extends to the bottom of the connecting plate 3 as a connecting end, which is used to install the fixing clip 6. When applying primer to the surface of the reflector, the fixing clip 6 clamps and fixes the reflector. Specifically, since the reflector has connecting ears on its outer periphery, and the connecting ears are hidden inside the lampshade after the reflector is connected to the lampshade, the fixing clip 6 can be clamped on the connecting ears of the reflector. After the primer is sprayed on one side of the reflector, the turning device above the connecting plate 3 can be used to drive each connecting rod 5 to rotate. This allows the reflector to be turned without contacting it, so that the turning operation can be performed directly on the other side of the reflector without waiting for the primer on one side of the reflector to dry. This shortens the time required to paint the entire reflector and improves the overall efficiency of the aluminum plating process.

[0021] In this embodiment, the steering device includes a drive ring 71. By opening a guide groove 31 on the connecting plate 3, the bottom end of the drive ring 71, that is, the coupling end adapted to the guide groove 31, can be directly fitted into the guide groove 31 when assembling the drive ring 71 with the connecting plate 3. After pushing the drive ring 71, the coupling end and the guide groove 31 can form a sliding fit, thus realizing the rotation of the drive ring 71. In addition, a transmission rack 73 is provided on the drive ring 71, and a transmission gear 72 is fixedly fitted on the extension end of the connecting rod 5. Thus, during the rotation of the drive ring 71, the transmission rack 73 and the transmission gear 72 mesh, which can drive the connecting rod 5 to rotate, thereby driving the reflector to turn.

[0022] It should be noted that both the transmission rack 73 and the transmission gear 72 are made of plastic. Since the paint contains moisture during the primer spraying process, the transmission rack 73 and transmission gear 72 are made of plastic to avoid rusting due to the paint. This ensures the stability of the meshing of the transmission rack 73 and transmission gear 72 during long-term use. Furthermore, in this design, the distribution angle of the transmission rack 73 is not 360°. Since the rotation of the connecting rod 5 is mainly achieved by manually pushing the drive ring 71, the excessive resistance encountered when the transmission rack 73 meshes with the transmission gears 72 on each connecting rod 5 simultaneously can be avoided, thus facilitating the rotation of the drive ring 71.

[0023] In this embodiment, an upwardly extending lever 8 is further fixed on the drive ring 71. By setting the lever 8, it is easier to apply force when pushing the drive ring 71 to rotate, thus making it easier to push the drive ring 71 to rotate.

[0024] In this embodiment, after the drive ring 71 is installed into the guide groove 31, a limiting cover plate 9 can be installed. The limiting cover plate 9 abuts against the surface of the drive ring 71, which can axially limit the drive ring 71. This can prevent the drive ring 71 from disengaging from the guide groove 31 during rotation, thereby improving the stability of long-term use. The connection between the limiting cover plate 9 and the connecting plate 3 is mainly achieved through the second threaded hole 91 and the first threaded hole 32 respectively provided on the limiting cover plate 9 and the connecting plate 3. By aligning the first threaded hole 32 with the second threaded hole 91 and screwing in a locking member that can form a threaded engagement with the first threaded hole 32 and the second threaded hole 91, the fixing between the limiting cover plate 9 and the connecting plate 3 can be completed.

[0025] In this embodiment, the connection and fixation between the connecting sleeve 2 and the shaft 1 is mainly achieved by the friction generated between the connecting sleeve 2 and the shaft 1 after the connecting sleeve 2 is fitted onto the outer circumference of the shaft 1. Therefore, in order to prevent the connecting sleeve 2 from loosening, a third threaded hole is further provided on the connecting sleeve 2. In this way, after the connecting sleeve 2 fitted onto the outer circumference of the shaft 1 is slid to a suitable position, the tightening bolt 10 can be screwed into the third threaded hole to press the tightening bolt 10 against the outer circumference of the shaft 1, thereby fixing the connecting sleeve 2 and improving the connection stability between the connecting sleeve 2 and the shaft 1.

[0026] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
