[0039] The present invention will now be described in further detail with reference to the accompanying drawings.

[0040] like Figures 2 to 5 As shown below, the steps and functions of a car wheel hub will be explained in detail.

[0041] A car wheel hub, a wheel hub 11, a support plate 12 fixedly connected to the wheel hub 11, a plurality of inclined blocks I 13 are provided inside the wheel hub 11, a support ring 21 is rotatably connected inside the wheel hub 11, a plurality of inclined blocks II 22 are fixedly connected to the support ring 21, and the plurality of inclined blocks II 22 can contact the plurality of inclined blocks I 13.

[0042] When using, such as Figure 2 As shown, when it is necessary to increase the strength of the hub 11, the support ring 21 is rotated. The rotation of the support ring 21 drives the multiple inclined blocks II 22 on it to rotate. The multiple inclined blocks II 22 press the multiple inclined blocks I 13 through the inclined surfaces, so that the multiple inclined blocks I 13 tend to move outward, increasing the stress inside the hub 11, thereby increasing the strength of the hub 11.

[0043] Furthermore, the inclined block II22 is made of an elastic material, preferably a rubber material;

[0044] In order to facilitate the rotation of the drive support ring 21, a power mechanism I for driving the support ring 21 to rotate is fixedly connected to the hub 11. The power mechanism I is preferably a servo motor.

[0045] When the power mechanism I is started, the output shaft of the power mechanism I begins to rotate. The output shaft of the power mechanism I drives the support ring 21 to rotate, and the support ring 21 drives multiple inclined blocks II 22 to rotate. The multiple inclined blocks II 22 rotate and squeeze the inclined block I 13.

[0046] Furthermore, during vehicle movement, the increased force on the wheel hub 11 due to tire deflation can cause deformation of the wheel hub 11, leading to damage. To overcome this technical problem, a sensor is installed inside the tire. The sensor can be a contact sensor. When the tire leaks air, the tire compresses the sensor. The sensor is connected to the power mechanism I via an electronic control method commonly used in the art. The output shaft of the power mechanism I starts to rotate, which drives the support ring 21 to rotate, supporting the wheel hub 11 and increasing its strength.

[0047] like Figure 1 As shown below, the steps and functions of a method for making an automobile wheel hub are explained in detail.

[0048] A method for manufacturing an automobile wheel hub, the method comprising the following steps:

[0049] Step 1: Clamp the wheel hub 11 between multiple drive wheels 33, and clamp the wheel hub 11 with two clamping discs 42;

[0050] Step 2: Drive the two cutting wheels 65 to move, and the cutting wheels 65 drive the multiple cutting tools 66 to rotate;

[0051] Step 3: Multiple cutting tools 66 move laterally to cut inside the hub 11, forming an inclined block I 13 inside the hub 11.

[0052] like Figures 6 to 10 As shown, in order to facilitate the processing of inclined block I13, an automobile wheel hub production device is designed. The structure and function of the automobile wheel hub production device are described in detail below.

[0053] An automobile wheel hub production device includes a device support 31, on which a plurality of telescopic mechanisms I 32 are fixedly connected. Each telescopic mechanism I 32 is rotatably connected to a drive wheel 33. A power mechanism II for driving the drive wheel 33 to rotate is fixedly connected to the telescopic end of the telescopic mechanism I 32. The power mechanism II is preferably a servo motor.

[0054] A hub 11 is clamped between multiple drive wheels 33;

The two clamping plates 42 can contact the wheel hub 11. The two clamping brackets 41 are respectively threaded to both ends of the lead screw I 34.

[0057] A transverse support 51 is slidably connected to the device bracket 31. The transverse support 51 is threadedly connected to the lead screw II 35. A telescopic mechanism II 52 is fixedly connected to the transverse support 51. A rotating disk 53 is rotatably connected to the telescopic end of the telescopic mechanism II 52. A power mechanism V for driving the rotating disk 53 to rotate is fixedly connected to the telescopic end of the telescopic mechanism II 52. The power mechanism V is preferably a servo motor.

[0058] A rotating ring 61 is rotatably connected to the rotating disk 53. A telescopic mechanism III 62 is fixedly connected to the rotating ring 61. A cutting bracket 63 is fixedly connected to the telescopic end of the telescopic mechanism III 62. A drive shaft 64 is rotatably connected to the cutting bracket 63. Two cutting wheels 65 are slidably connected to the drive shaft 64. Multiple cutting blades 66 are fixedly connected to each cutting wheel 65. The multiple cutting blades 66 are staggered with each other. Two telescopic mechanisms IV 67 are fixedly connected to the cutting bracket 63. A push ring 68 is fixedly connected to the telescopic end of each of the two telescopic mechanisms IV 67. The two push rings 68 are rotatably connected to the two cutting wheels 65 respectively.

[0059] A power mechanism VI for driving the rotating ring 61 to rotate is fixedly connected to the rotating disk 53. The power mechanism VI is preferably a servo motor. A power mechanism VII for driving the drive shaft 64 to rotate is fixedly connected to the cutting bracket 63. The power mechanism VII is preferably a servo motor.

[0060] like Figure 6 As shown, the hub 11 is placed between multiple drive wheels 33, and the telescopic mechanism I 32 is activated. The telescopic mechanism I 32 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I 32 drives the drive wheels 33 to move, and the multiple drive wheels 33 move closer to each other, clamping the hub 11.

[0061] When the power mechanism III is started, the output shaft of the power mechanism III drives the lead screw I 34 to rotate. When the lead screw I 34 rotates, it drives the two clamping brackets 41 to move through the thread. The two clamping brackets 41 move closer or further away from each other. The two clamping brackets 41 drive the two clamping discs 42 to move. The two clamping discs 42 move closer to each other and clamp the side of the wheel hub 11, thereby completing the fixation of the wheel hub 11.

[0062] Start the power mechanism VII. The output shaft of the power mechanism VII drives the drive shaft 64 to rotate. The drive shaft 64 drives the two cutting wheels 65 to rotate. The cutting wheels 65 drive the cutting tools 66 to rotate. Multiple cutting tools 66 rotate together. Start the power mechanism IV. The output shaft of the power mechanism IV starts to rotate. The output shaft of the power mechanism IV drives the lead screw II 35 to rotate. When the lead screw II 35 rotates, it drives the transverse support 51 to move through the thread. The transverse support 51 drives the telescopic mechanism II 52 to move. The telescopic mechanism II 52 drives the rotating disk 53 to move. The rotating disk 53 drives the rotating ring 61 to move. The rotating ring 61 drives multiple cutting tools 66 to move, so that multiple cutting tools 66 pass through the inside of the hub 11 and cut to form an inclined notch inside the hub 11.

[0063] Furthermore, the telescopic mechanism II 52 is activated. The telescopic mechanism II 52 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism II 52 drives the rotating disk 53 to move. The rotating disk 53 drives the rotating ring 61 to move. The rotating ring 61 drives multiple cutting tools 66 to move, thereby adjusting the position of the multiple cutting tools 66.

[0064] Furthermore, the power mechanism V is activated, and the output shaft of the power mechanism V begins to rotate. The output shaft of the power mechanism V drives the rotating disk 53 to rotate, the rotating disk 53 drives the rotating ring 61 to move, and the rotating ring 61 drives multiple cutting tools 66 to move, thereby adjusting the tilt direction of the multiple cutting tools 66.

[0065] Furthermore, the power mechanism VI is activated, and the output shaft of the power mechanism VI drives the rotating ring 61 to rotate. The rotating ring 61 drives multiple cutting tools 66 to move, thereby adjusting the tilt direction of the multiple cutting tools 66.

[0066] Furthermore, the telescopic mechanism Ⅲ62 is activated. The telescopic mechanism Ⅲ62 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism Ⅲ62 drives multiple cutting tools 66 to move, thereby adjusting the height of the multiple cutting tools 66.

[0067] Furthermore, by activating the telescopic mechanism II 52, power mechanism V, power mechanism VI, and telescopic mechanism III 62, the positions of multiple cutting tools 66 can be adjusted to meet different processing requirements;

[0068] Furthermore, after the multiple cutting tools 66 complete the first cut, the power mechanism II is started. The output shaft of the power mechanism II drives the drive wheel 33 to rotate, and the drive wheel 33 drives the hub 11 to rotate, adjusting the cutting position of the hub 11. The multiple cutting tools 66 cut the hub 11 multiple times, and the inclined block I 13 is formed inside the hub 11.

[0069] Furthermore, when it is necessary to adjust the cutting width of multiple cutting tools 66, the telescopic mechanism IV 67 is activated. The telescopic mechanism IV 67 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism IV 67 drives the push ring 68 to move. The push ring 68 pulls the cutting wheel 65 to slide on the drive shaft 64, thereby adjusting the cutting width composed of multiple cutting tools 66 on both sides to meet different processing requirements.
