DETAILED DESCRIPTION

[0017] The wheel processing hanger of the present invention will be described below with reference to the accompanying drawings.

[0018] In Example 1 of the present application, Figure 1 and Figure 2 As shown, the wheel processing hanger (hereinafter referred to as "the present invention") includes a suspension chain lap rod 1, an upper stabilizing plate 2, a main vertical rod 3, a rolling rod 4, a rolling rod support arm 5, a hub guide support rolling rod 6, a guide support rolling rod support arm 7, an upper connecting rod 8, a lower connecting rod 9, and a lower stabilizing plate 10. The top of the main vertical rod 3 is connected to the upper stabilizing plate 2 through the upper connecting rod 8. The suspension chain lap rod 1 is set at the upper center of the upper stabilizing plate 2. Two sets of wheel mounting rod assemblies are respectively installed on the upper and lower sides of the main vertical rod 3. The two rolling rods 4 of the wheel mounting rod assembly are connected to the upper and lower sides of the main vertical rod 3. A rolling rod reference plane is formed by symmetrically installing the rolling rod support arm 5 on the side of the main vertical rod 3, and the wheel hub guide support rolling rod 6 is installed on the side of the main vertical rod 3 perpendicular to the rolling rod reference plane through the guide support rolling rod support arm 7; the rolling rod 4 and the wheel hub guide support rolling rod 6 are tilted upward by fifteen degrees; a rotating shaft is provided at the end of the rolling rod 4, and the rotating shaft is inserted into the bearing built into the rolling rod support arm 5; the rotating shaft is fixedly installed at the base of the wheel hub guide support rolling rod 6, and the rotating shaft is inserted into the bearing built into the guide support rolling rod support arm 7; the wheel hub guide support rolling rod 6 is a spring plate covered with plastic.

[0019] The utility model announcement number is CN218611216U, which is a lightweight wheel hub pre-treatment hanger (hereinafter referred to as "the patent"). The patent has made important improvements in structure and lightweighting. However, this has increased the contact points between the wheel hub and the hanger. These contact surfaces will affect the pre-treatment effect and thus affect the yield rate. The present invention uses a rolling rod 4 that can rotate the wheel hub and a wheel hub guide support rolling rod 6, so that the wheel hub can rotate within a certain range during treatment, so that the contact surface is no longer fixed, so that the wheel hub surface can be pre-treated evenly.

[0020] The structure of the second embodiment is basically the same as that of the first embodiment, except that Figure 3As shown, the lower end of the main vertical rod 3 is connected to the lower stabilizing plate 10 through the lower connecting rod 9. The lower stabilizing plate 10 has a built-in battery pack and is connected to the motor and controller in the upper stabilizing plate 2 through wires. The motor output shaft in the upper stabilizing plate 2 drives the main transmission shaft in the main vertical rod 3 through a bevel gear and a connecting rod. The main transmission shaft is connected to the rolling rod 4 and the hub guide supporting the rotating shaft of the rolling rod 6 through the bevel gear sleeved thereon.

[0021] To further optimize the performance of this application and facilitate replacement of the lower stabilizing plate 10, the connecting rod 9 is mounted to the lower stabilizing plate 10 via threads and annular metal contacts. To protect the wheel hub from damage, the rolling rod 4 is coated in plastic. The wheel hub guide and support rolling rod 6 is a steel rod with a plastic coating on the exterior and ends.

[0022] When in use, install the wheel processing hanger on the suspension chain and the equipment can be put into use.

[0023] When the utility model is in use, the specific operations are as follows:

[0024] When in use, without installing the lower stabilizing plate 10, the robotic arm aligns the center hole of the wheel hub with the wheel hub guide support rolling rod 6 and mounts it on the wheel hub guide support rolling rod 6. After the end of the wheel hub guide support rolling rod 6 passes through the center hole of the wheel hub, it cooperates with the rolling rod 4 to support the wheel hub. During pretreatment, sandblasting and liquid flow give the wheel hub a tiny thrust. Since the movable rolling rod 4 and the wheel hub guide support rolling rod 6 are rotatable structures, the wheel hub can rotate, so that the contact surface is no longer fixed, so that the surface of the wheel hub can be evenly pretreated to prevent the occurrence of defects.

[0025] After installing the lower stabilizing plate 10, the robotic arm aligns the hub center hole with the hub guide support roller rod 6 and mounts it on the hub guide support roller rod 6. After the end of the hub guide support roller rod 6 passes through the hub center hole, it cooperates with the roller rod 4 to support the hub. When the equipment enters the pretreatment section, it receives a control signal and is powered by the battery pack built into the lower stabilizing plate 10. The motor in the upper stabilizing plate 2 drives the shaft in the upper connecting rod 8 through the rotating shaft and bevel gear. The rotating shaft in the upper connecting rod 8 drives the bevel gear at the top of the rotating shaft in the main vertical rod 3 through the bevel gear on the end. Then, driven by the bevel gear on the surface of the rotating shaft in the main vertical rod 3, it drives the rotating shaft of the roller rod 4 located in the roller rod support arm 5 and the rotating shaft of the hub guide support roller rod 6 located in the guide support roller rod support arm 7, thereby causing the roller rod 4 and the hub guide support roller rod 6 to slowly rotate, thereby allowing the hub surface to be pretreated evenly and preventing the occurrence of defects. Compared with passive rotation, actively rotating the hub can make the pretreatment more uniform and further ensure the treatment effect.

[0026] In summary, the wheel processing hanger of the embodiment of the present invention, by adding a rolling rod 4 that can rotate the wheel hub and a wheel hub guide support rolling rod 6, allows the wheel hub to rotate within a certain range during processing, so that the contact surface is no longer fixed, so that the wheel hub surface can be uniformly pre-processed, which can effectively improve the wheel hub yield.

Within the spirit and principles of the present invention, the technical features of the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and many other variations exist for the various aspects of the present invention described above, which are not provided in detail for the sake of clarity.
