A hanger for spray wheel hubs

Abstract

This application relates to the field of wheel hub hanger technology, and more particularly to a hanger for painting wheel hubs. The proposed technical solution includes a support frame, with a hanging cylinder fixedly connected to each end of the support frame. A pair of through slots are formed at the outer end of each hanging cylinder, and a limiting rod is installed within each through slot. A retraction and extension drive mechanism for controlling the limiting rods is provided within the hanging cylinder. By creating a pair of through slots at the ends of the hanging cylinders, the two limiting rods can extend out of the two through slots under the control of the retraction and extension drive mechanism, thereby limiting and preventing the hung wheel hub from detaching. This makes the process more stable and safer during painting. Furthermore, the two limiting rods can retract into the hanging cylinders without affecting the hanging and removal of the wheel hub, resulting in a higher safety factor for the entire hanger.

Description

Technical Field

[0001] This application relates to the field of wheel hub mounting technology, and more particularly to a mounting for spraying wheel hubs. Background Technology

[0002] Wheel painting is an important part of car maintenance. Its core goal is to enhance the uniqueness of a car's appearance by changing the color, gloss, or texture of the wheels, while also providing additional protection for the wheels.

[0003] During the painting process, wheel hubs need to be hung on a hanger to expose their outer surface for easy painting of every area. Existing hangers simply attach the center of the wheel hub directly to the hanger's support rod before painting. While this prevents direct spraying of the wheel hub, the direct hanging method (without a restraining structure) still poses certain safety hazards, as the stability of the wheel hub during painting is not guaranteed. Therefore, this application proposes a hanger for painting wheel hubs. Utility Model Content

[0004] The purpose of this application is to provide a hanger for spraying wheel hubs, addressing the technical problems identified in the background section.

[0005] The technical solution of this application is: a hanger for spraying wheel hubs, including a support frame, with a hanging cylinder fixedly connected to each end of the support frame, a pair of through grooves opened at the outer end of the hanging cylinder, a limit rod provided in the through groove, and a retraction and extension drive mechanism for controlling the limit rod provided in the hanging cylinder.

[0006] Preferably, the retraction drive mechanism includes a pair of deflection shafts rotatably connected inside the hanging cylinder, and the two limiting rods are respectively fixedly connected to the side walls of the two deflection shafts;

[0007] A double-sided rack is provided between the two deflection shafts, and a gear is fixedly sleeved on the middle sidewall of each of the two deflection shafts. The two teeth of the double-sided rack mesh with the two gears respectively for transmission.

[0008] Preferably, an installation block is fixedly connected to the inner wall of the other end of the hanging cylinder, and an electric cylinder is installed at the inner end of the installation block. The telescopic end of the electric cylinder is fixedly connected to a double-sided rack.

[0009] Preferably, a pair of support blocks are fixedly connected to the inner wall of the hanging cylinder, and the two deflection shafts are rotatably connected between the two support blocks;

[0010] Both of the limiting rods have grooves at their ends near the deflection shaft, and the two gears are respectively accommodated in the two grooves.

[0011] Preferably, a limiting plate is fixedly connected to the outer wall of the hanging cylinder for positioning the wheel hub on the hanging cylinder.

[0012] Preferably, the two limiting rods protrude from the outer wall of the hanging cylinder after unfolding, in order to prevent the attached wheel hub from falling off.

[0013] Preferably, the support frame includes three support rods, one of which is perpendicular to the ground and located vertically between the other two support rods.

[0014] Compared with the prior art, this application has the following beneficial technical effects:

[0015] This application provides a pair of through slots at the end of the hanging cylinder. The two limiting rods can extend out of the two through slots under the control of the retraction drive mechanism, thereby limiting and preventing the hanging wheel hub from falling off. This makes the process more stable and safe during the painting process. In addition, the two limiting rods can be retracted into the hanging cylinder without affecting the hanging and removal of the wheel hub.

[0016] In this application, the support frame is set with three support rods, one of which is perpendicular to the ground and located vertically between the other two support rods. The lower ends of the three hubs are located on different vertical planes, which avoids the sprayed material dripping and affecting the hubs below, and also saves the space for hanging.

[0030] Example

[0031] like Figures 1-4 As shown, this application discloses a wheel hub painting hanger, comprising a support frame 1, with a hanging cylinder 2 fixedly connected to each end of the support frame 1. A limiting plate 3 is fixedly connected to the outer wall of the hanging cylinder 2 for positioning the hung wheel hub. A pair of through slots 4 are provided at the outer end of the hanging cylinder 2, and limiting rods 5 are provided in the through slots 4. A retraction and extension drive mechanism 7 for controlling the limiting rods 5 is provided in the hanging cylinder 2, allowing the two limiting rods 5 to be extended and retracted into the hanging cylinder 2. After the wheel hub is hung, the two limiting rods 5 are extended, protruding from the outer wall of the hanging cylinder 2 to prevent the hung wheel hub from falling off; when hanging or removing the wheel hub, the two limiting rods 5 are retracted into the hanging cylinder 2.

[0032] Specifically, the retraction drive mechanism 7 includes a pair of deflection shafts 71 rotatably connected inside the hanging cylinder 2, and two limiting rods 5 are respectively fixedly connected to the side walls of the two deflection shafts 71; a double-sided rack 73 is provided between the two deflection shafts 71, and gears 72 are fixedly sleeved on the middle side walls of both deflection shafts 71, with the two teeth of the double-sided rack 73 meshing with the two gears 72 respectively. A sliding groove is formed on the inner wall of the hanging cylinder 2, and a support rod is connected to one side of the double-sided rack 73, slidingly connected within the sliding groove (not shown in the figure due to perspective). A mounting block 8 is fixedly connected to the inner wall of the other end of the hanging cylinder 2, and an electric cylinder 6 is mounted on the inner end of the mounting block 8. The telescopic end of the electric cylinder 6 is fixedly connected to the double-sided rack 73.

[0033] The inner wall of the hanging cylinder 2 is fixedly connected to a pair of support blocks 75. The surfaces of the two support blocks 75 that are close to each other are flat, and each of the surfaces of the two support blocks 75 has a pair of support bearings embedded therein. The two deflection shafts 71 are rotatably connected between the two support blocks 75, and the two deflection shafts 71 are fixedly connected to the inner rings of the two pairs of support bearings respectively. The ends of the two limiting rods 5 near the deflection shafts 71 are each provided with a groove 74, and the two gears 72 are respectively accommodated in the two grooves 74, so that the two gears 72 can rotate normally.

[0034] Specifically, the support frame 1 includes three support rods, one of which is perpendicular to the ground and located vertically between the other two support rods. The lower ends of the three hubs are located on different vertical planes, which prevents the sprayed material from dripping and affecting the lower hubs, thus affecting the local spraying effect, and also saves hanging space.

[0035] The working principle of this embodiment is as follows: First, the support frame 1 is fixed on the external fixed frame, so that several hanging cylinders 2 are parallel to the ground. Before the wheel hub is hung, the limiting rod 5 on each hanging cylinder 2 is stored in the corresponding hanging cylinder 2. The wheel hub to be sprayed is hung on several hanging cylinders 2. The limiting plate 3 on the side wall of the hanging cylinder 2 can limit the wheel hub. After the wheel hub is hung, the electric cylinder 6 is started. The telescopic end of the electric cylinder 6 extends towards the through groove 4, thereby driving the double-sided rack 73 to move towards the through groove 4. The double-sided rack 73 meshes with two gears 72, causing the two deflection shafts 71 to rotate in opposite directions, thereby causing the two limiting rods 5 to rotate to the two through grooves 4, until the two limiting rods 5 are perpendicular to the two through grooves 4. When the two limiting rods 5 are perpendicular to the two through grooves 4, the outer ends of the two limiting rods 5 protrude from the outer side wall of the hanging cylinder 2, thereby limiting and preventing the hung wheel hub from falling off, making the spraying process more stable and safe. When the paint is dry and the hub needs to be removed, the telescopic end of the electric cylinder 6 is retracted, causing the double-sided rack 73 to mesh with the two gears 72 in the opposite direction, which in turn drives the two deflection shafts 71 to rotate in the opposite direction, causing the two limit rods 5 to rotate to the inside of the hanging cylinder 2. The next step is to remove the hub to one side.

[0036] The above specific embodiments are merely preferred embodiments of this application. Based on the technical solutions of this application and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments. The above specific embodiments are merely explanations of this application and are not limitations on this application.
