[0046] The present invention will now be described in further detail with reference to the accompanying drawings.

[0047] like Figures 4 to 9 As shown below, the structure and function of a car wheel hub will be described in detail.

[0048] A car wheel hub includes a wheel hub 11, which has three mounting holes 12 and an air inlet 13. A rotating disk 21 is rotatably connected inside the wheel hub 11. The rotating disk 21 has two arc-shaped waist holes 22. Each arc-shaped waist hole 22 is slidably connected to an extrusion cylinder 23. Each extrusion cylinder 23 is threadedly connected to a positioning screw I 24 for positioning. A drive gear 25 is rotatably connected to the wheel hub 11 to drive the rotating disk 21 to rotate. The drive gear 25 and the rotating disk 21 mesh and transmit power.

[0049] A power mechanism I for driving the drive gear 25 to rotate is fixedly connected to the hub 11. The power mechanism I is preferably a servo motor.

[0050] One of the mounting holes 12 is connected to a threaded post 31 by a thread, and a sensor 32 is fixedly connected to the threaded post 31. The power mechanism I is connected to the sensor 32.

[0051] The other two mounting holes 12 are each connected to a mounting sleeve 42 by a thread. Each mounting sleeve 42 is fixedly connected to a storage cylinder 41. Each storage cylinder 41 is slidably connected to a pressing plate 43. Each pressing plate 43 is fixedly connected to a pressing boss 44. A compression spring is fixedly connected between the pressing boss 44 and the storage cylinder 41. A one-way mechanism 45 is provided inside the mounting sleeve 42.

[0052] The two extrusion cylinders 23 can respectively extrude the two extrusion protrusions 44, so that the two extrusion plates 43 can slide in the two storage cylinders 41 respectively;

[0053] When using, such as Figure 4As shown, two mounting sleeves 42 are pre-connected to two mounting holes 12 by threads. One storage cylinder 41 contains tire repair fluid, and the other storage cylinder 41 contains tire gas. The tire sleeve is mounted on the wheel hub 11, and the mounting threaded post 31 is connected to the remaining mounting hole 12 by threads, so that the sensor 32 extends into the inside of the tire. The tire is inflated through the air inflator 13, which is equipped with a one-way valve to ensure that the gas can only be injected into the tire and cannot be discharged from the tire. The distance between the sensor 32 and the tire is adjusted. The sensor 32 can be a contact sensor or a squeeze sensor.

[0054] The wheel hub 11 is mounted on the drive shaft of the car. When the tire is punctured and leaks air during driving, the air inside the tire is released, and the tire can no longer maintain its original shape. Under pressure, the tire deforms to a certain extent, and the inner side of the tire squeezes the sensor 32. The sensor 32 is connected to the power mechanism I through the electronic control technology commonly used in the art. When the sensor 32 is squeezed, the sensor 32 controls the output shaft of the power mechanism I to start rotating. The output shaft of the power mechanism I drives the drive gear 25 to rotate, and the drive gear 25 drives the rotating disk 21 to rotate. The rotating disk 21 drives the two extrusion cylinders 23 to rotate. One of the extrusion cylinders 23 first contacts the extrusion protrusion 44 corresponding to the storage cylinder 41 containing tire repair fluid. The extrusion cylinder 23 squeezes the extrusion protrusion 44. 4. Push the extrusion plate 43 to slide inside the storage cylinder 41, so that the tire repair fluid in the storage cylinder 41 is introduced into the tire through the mounting sleeve 42. As the tire rotates, the tire's interior is repaired. Then, another extrusion cylinder 23 contacts the extrusion protrusion 44 corresponding to the tire gas storage cylinder 41. The extrusion cylinder 23 extrudes the extrusion protrusion 44, and the extrusion protrusion 44 pushes the extrusion plate 43 to slide inside the storage cylinder 41, so that the gas in the storage cylinder 41 is introduced into the tire through the mounting sleeve 42, thereby supporting the tire's interior. This can perform preliminary repairs on the tire's interior and support the car's movement. It should be noted that this repair is only suitable for minor tire damage and can temporarily provide some repair, ensuring that the car can still travel a certain distance even with a damaged tire.

[0055] like Figures 1 to 3 As shown, since the wheel hub 11 is provided with three mounting holes 12 and one air inlet 13, in order to facilitate the machining of the holes on the wheel hub 11, a manufacturing method for automobile wheel hub is designed.

[0056] A method for manufacturing an automobile wheel hub, the method comprising the following steps:

[0057] S1: Place the hub 11 on the outside of multiple support rollers 63, with the multiple support rollers 63 moving away from each other to clamp the hub 11;

[0058] S2: Replace the model of the support hole 65 on the support roller 63, and replace the model of the punching tool 74;

[0059] S3: The drilling tool 74 and the support hole 65 work together to drill holes in the wheel hub 11;

[0060] In S2, changing the model of the support hole 65 on the support roller 63 includes the following steps:

[0061] S201: Drive the support roller 63 located at the punching position to rotate;

[0062] S202: The support roller 63 located on the opposite side of the punching position rotates in the opposite direction to the support roller 63 at the punching position, while the support rollers 63 at other positions do not rotate.

[0063] S203: The support roller 63 at the punching position is spinning idly and will not drive the hub 11 to rotate. Replace the support roller 63 at the punching position with the model of the support hole 65.

[0064] In S2, changing the model of the punching tool 74 includes the following steps:

[0065] S211: Drives the tool changer 73 to rotate;

[0066] S212: The tool changer 73 drives multiple drilling tools 74 to rotate;

[0067] S223: Replace with a 74-type punching tool.

[0068] like Figures 10 to 13 As shown, in order to facilitate the implementation of a method for manufacturing automobile wheel hubs, an automobile wheel hub manufacturing device is designed. The structure and function of the automobile wheel hub manufacturing device are described in detail below.

[0069] A manufacturing apparatus for automobile wheel hubs includes an apparatus support 51, a telescopic mechanism I 52 fixedly connected to the apparatus support 51, a tension seat 53 fixedly connected to the telescopic end of the telescopic mechanism I 52, and a plurality of connecting rods 54 hinged to the tension seat 53.

[0070] Multiple sliding seats 61 are slidably connected to the device bracket 51, and multiple connecting rods 54 are respectively hinged to multiple sliding seats 61. A drive motor 62 is fixedly connected to each sliding seat 61, and a support roller 63 is fixedly connected to the output shaft of the drive motor 62. Multiple support holes 65 are provided on each support roller 63, and the multiple support holes 65 are of different types.

[0071] Each support roller 63 is slidably connected to a limit plate 64, and a positioning screw II is threadedly connected to the limit plate 64.

[0072] A telescopic mechanism II 71 is fixedly connected to the device bracket 51. A lifting bracket 72 is fixedly connected to the telescopic end of the telescopic mechanism II 71. A tool changer 73 is rotatably connected to the lifting bracket 72. Multiple punching tools 74 are rotatably connected to the tool changer 73. The multiple punching tools 74 are of different models.

[0073] A power mechanism II for driving the tool changer 73 to rotate is fixedly connected to the lifting bracket 72. The power mechanism II is preferably a servo motor. A power mechanism III for driving the drilling tool 74 to rotate is fixedly connected to the tool changer 73. The power mechanism III is preferably a servo motor.

[0074] In use, the hub 11 is placed on the outside of multiple support rollers 63, and the telescopic mechanism I 52 is activated. The telescopic mechanism I 52 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I 52 drives the tension seat 53 to move. The tension seat 53 drives multiple connecting rods 54 to move. The connecting rods 54 drive the sliding seat 61 to move. The sliding seat 61 drives the drive motor 62 to move. The drive motor 62 drives the support rollers 63 to move. The positions of the multiple support rollers 63 are adjusted so that the multiple support rollers 63 are far apart from each other. The multiple support rollers 63 support and clamp the inner side of the hub 11.

[0075] Start the telescopic mechanism II 71, which can be a hydraulic cylinder or an electric push rod. Start the power mechanism III. The output shaft of the power mechanism III drives the drilling tool 74 to rotate. The telescopic end of the telescopic mechanism II 71 drives the lifting bracket 72 to move. The lifting bracket 72 drives the drilling tool 74 to move downward. The drilling tool 74 and the support hole 65 cooperate to drill holes in the wheel hub 11. This support and drilling method can effectively prevent the wheel hub 11 from deforming.

[0076] Because the mounting holes 12 that need to be machined on the hub 11 are of different types and sizes, in order to machine mounting holes 12 of different sizes;

[0077] Start the drive motor 62. The output shaft of the drive motor 62 starts to rotate. The output shaft of the drive motor 62 drives the corresponding support roller 63 to rotate. The support roller 63 located at the drilling position rotates in the opposite direction to the support roller 63 at the drilling position. The support rollers 63 at other positions do not rotate. The support roller 63 at the drilling position spins idly and does not drive the hub 11 to rotate. Change the model of the support hole 65 on the support roller 63 at the drilling position. Start the power mechanism II. The output shaft of the power mechanism II starts to rotate. The output shaft of the power mechanism II drives the tool changer 73 to rotate. The tool changer 73 drives multiple drilling tools 74 to rotate. Change the model of the drilling tool 74. The drilling tool 74 and the support hole 65 cooperate to drill holes in the hub 11.

[0078] Furthermore, in order to adjust the position of the mounting hole 12 on the hub 11, the support roller 63 is driven to rotate, so that multiple support rollers 63 rotate in the same direction, thereby driving the hub 11 to rotate, and thus adjusting the position of the hole.

[0079] Furthermore, such as Figure 10 As shown, in order to position the hub 11, the inner side of the hub 11 rests on the limiting plate 64. The position of the limiting plate 64 can be adjusted on the support roller 63, thereby adjusting the drilling position on the hub 11.
