[0021] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figures 1-5 In this embodiment of the utility model, a hub center positioning device includes a fixed base 1, a groove 2 inside the fixed base 1, a drive motor 3 installed inside the groove 2, a connecting rod 4 connected to the output end of the drive motor 3, a positioning disk 5 connected to the top end of the connecting rod 4, a positioning post 6 connected to the upper surface of the positioning disk 5, a fixing ring 7 sleeved on the outer surface of the positioning post 6, and a set of circularly arranged positioning plates 8 connected to the outer surface of the fixing ring 7. A positioning block 9 is connected to the end of each positioning plate 8 away from the fixing ring 7. Threaded holes 10 are opened inside each positioning block 9 and on the upper surface of the positioning disk 5. A fastening screw 11 is provided above each positioning block 9. The drive motor 3 can drive the connecting rod 4 and the positioning disk 5 to rotate, thus enabling the positioning disk 5 to drive the hub to rotate at multiple angles without manual adjustment, reducing the difficulty of operation and improving work efficiency.

[0024] Each fastening screw 11 is adapted to the threaded hole 10. The outer surface of each fastening screw 11 is coated with an anti-rust coating. A set of guide grooves 12 are opened on the inner side wall of the fixing ring 7. A set of guide blocks 13 are connected to the outer surface of the positioning post 6. A protective pad 14 is connected to the bottom surface of each positioning plate 8. The outer surface of each protective pad 14 is provided with anti-slip texture. The anti-rust coating on the surface of the fastening screw 11 can effectively resist the corrosion of the external environment and extend its service life. The cooperation of the guide block 13 and the guide groove 12 reduces the wear of the fixing ring 7 during the sliding process, improves the stability and durability of the overall structure of the device, and reduces maintenance costs. The protective pad 14 on the bottom surface of the positioning plate 8 can not only avoid the wear caused by the direct contact between the positioning plate 8 and the wheel hub, but the anti-slip texture on its surface can also increase the friction with the wheel hub and prevent the surface of the wheel hub from being scratched, thus playing a dual protection role.

[0025] An annular groove 15 is formed on the upper surface of the fixed base 1. An annular plate 16 is slidably connected inside the annular groove 15. The top of the annular plate 16 is connected to the bottom surface of the positioning disk 5. Two control buttons 17 are installed on the front of the fixed base 1. A model nameplate 18 is connected to the front of the fixed base 1. Two L-shaped connecting brackets 19 are connected to the bottom surface of the fixed base 1. Each L-shaped connecting bracket 19 has a mounting hole 20 inside. Through the sliding cooperation between the annular groove 15 and the annular plate 16, the stability of the positioning disk 5 during rotation is improved, and the impact of vibration on the machining accuracy is reduced. The control buttons 17 facilitate the operation and control of the drive motor 3. The model nameplate 18 makes it easy for operators to identify equipment information, which meets the requirements of standardized management. The L-shaped connecting brackets 19 and the mounting holes 20 make it easy to install the device firmly on the workbench, ensuring that the device will not shift during operation, providing a solid foundation for wheel hub positioning.

[0026] The working principle of this utility model is as follows: When using this device, firstly, the wheel hub is placed on the positioning plate 5, so that the center hole of the wheel hub fits into the positioning post 6, initially achieving center alignment. Then, the fixing ring 7 is fitted outside the positioning post 6. The annularly arranged positioning plates 8 and positioning blocks 9 connected to its outer side can form a circumferential support for the inner edge of the wheel hub. By adjusting the position of the fixing ring 7 on the positioning post 6, combined with the cooperation of the guide groove 12 and the guide block 13, the movement direction of the positioning plate 8 is ensured to be stable. Then, the fit between the positioning block 9 and the wheel hub is adjusted. After the position is determined, the fastening screw 11 is screwed into the threaded hole 10 on the positioning block 9 and the positioning plate 5 to fix the positioning block 9, thereby completing the center positioning operation of the wheel hub. The above is the complete operation process of this device.
