[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] like Figures 1 to 9 As shown, a car wheel hub pressure testing tool includes a base plate 1, a U-shaped plate 2 fixedly connected to the upper surface of the base plate 1, and first horizontal plates 3 fixedly connected to both the left and right sides of the inner wall of the U-shaped plate 2. A circular hole 4 is opened inside the first horizontal plate 3, and a first guide sleeve 5 is fixedly connected to the inner wall of the circular hole 4. A guide post 6 is fitted against the inner wall of the first guide sleeve 5, a placement plate 7 is fixedly connected to the upper surface of the guide post 6, a circular ring 8 is fixedly connected to the surface of the guide post 6, a spring 9 is fixedly connected to the upper surface of the circular ring 8, and a second guide sleeve 10 is fixedly connected to the upper surface of the spring 9. The inner wall of the second guide sleeve 10 is fitted against the surface of the guide post 6. The surface of the second guide sleeve 10 is fixedly connected to the second horizontal plate 11, the upper surface of the bottom plate 1 is fixedly connected to the push plate mechanism 12, the top of the inner wall of the U-shaped plate 2 is fixedly connected to the electric push rod 13, the bottom of the electric push rod 13 is fixedly connected to the third horizontal plate 14, the bottom of the third horizontal plate 14 is fixedly connected to the pressure sensor 15, the bottom of the pressure sensor 15 is fixedly connected to the pressing plate 16, the right side of the U-shaped plate 2 is fixedly connected to the first support plate 17, the front of the first support plate 17 is fixedly connected to the box body 18, the front of the box body 18 is fixedly connected to the touch screen display 19, and the inner wall of the box body 18 is fixedly connected to the controller 20.

[0025] The push plate mechanism 12 includes a mounting base 121, a drive motor 122, a rotating shaft 123, an elliptical disk 124, a bearing 125, and a support block 126. The bottom of the mounting base 121 is fixedly connected to the upper surface of the base plate 1. The upper surface of the mounting base 121 is connected to the bottom of the drive motor 122. The output end of the drive motor 122 is fixedly connected to the right end of the rotating shaft 123. The surface of the rotating shaft 123 is fixedly connected to the inner wall of the elliptical disk 124. The surface of the rotating shaft 123 is fixedly connected to the inner ring of the bearing 125. The outer ring of the bearing 125 is fixedly connected to the inner wall of the support block 126. The bottom of the support block 126 is fixedly connected to the upper surface of the base plate 1.

[0026] The pressure sensor 15 is a GE180K, the touch screen display 19 is a Kunlun Tongtai TPC1021KT, the controller 20 is a Honeywell PEC8044_PB1_SO, the electric actuator 13 is a UD100, and the drive motor 122 is a TWX-09E. The electric actuator 13 and the pressure sensor 15 are both connected to the serial port (e.g., COM1) of the controller 20 via RS485. After parsing the data, the controller 20 forwards it to the touch screen display 19 via another serial port (e.g., COM2) or Ethernet. The driver on the drive motor 122 is connected to the serial port (e.g., COM1) of the controller 20 via RS485.

[0027] It should be noted that the guide post 6 can slide up and down on the first guide sleeve 5, and the second guide sleeve 10 can slide up and down on the guide post 6. When the drive motor 122 drives the elliptical disk 124 to rotate, the rotating elliptical disk 124 causes the second horizontal plate 11 to move up and down reciprocally. The reciprocating movement of the second horizontal plate 11 causes the tension of the spring 9 on the ring 8 to fluctuate. At this time, the pressure on the wheel hub during the pressure test is constantly changing. After the wheel hub is placed on the placement plate 7, the electric push rod 13 can be used to press... The plate 16 presses against the wheel hub, and the pressure sensor 15 monitors the pressure applied by the pressing plate 16. When the pressure of the pressing plate 16 on the wheel hub reaches the set value, the controller 20 controls the electric push rod 13 to stop extending according to the data transmitted by the pressure sensor 15. At this time, the pressure of the pressing plate 16 on the wheel hub will not increase after reaching the set value. The initial pressure of the pressing plate 16 on the wheel hub can be set through the touch screen 19, and the start and stop of the drive motor 122 and the extension and retraction of the electric push rod 13 can also be controlled.

[0028] like Figures 1 to 4 As shown, a rectangular hole 21 is provided inside the placement plate 7. A slider 22 is fitted to the inner wall of the rectangular hole 21. An arc-shaped positioning post 23 is fixedly connected to the upper surface of the slider 22. The bottom of the arc-shaped positioning post 23 is fitted to the upper surface of the placement plate 7. A hollow block 24 is fixedly connected to the bottom of the slider 22. The upper surface of the hollow block 24 is fitted to the bottom of the placement plate 7. A threaded cylinder 25 is fixedly connected to the inner wall of the hollow block 24. A bolt 26 is threadedly connected to the inner wall of the threaded cylinder 25. A rubber strip 27 is fitted to the back of the bolt 26. A second support plate 28 is adhered to the back of the rubber strip 27. The upper surface of the second support plate 28 is fixedly connected to the bottom of the placement plate 7. A scale 29 is fixedly connected to the front of the placement plate 7. The bottom of the scale 29 is fitted to the bottom of the threaded cylinder 25.

[0029] There are two arc-shaped positioning posts 23, and the two arc-shaped positioning posts 23 are located on the left and right sides of the center of the placement plate 7, respectively.

[0030] It should be noted that the arc-shaped positioning post 23 can be used to position the wheel hub placed on the placement plate 7. Through the cooperation of the arc-shaped positioning post 23 and the hollow block 24, the slider 22 can only slide left and right within the rectangular hole 21. Through the threaded cylinder 25, when the user rotates the bolt 26, the bolt 26 can be made to contact or separate from the rubber strip 27. When the bolt 26 contacts the rubber strip 27, the friction between the rubber strip 27 and the bolt 26 prevents the arc-shaped positioning post 23 from moving. When the bolt 26 separates from the rubber strip 27, the arc-shaped positioning post 23 can move left and right on the placement plate 7. The scale 29 allows the user to intuitively judge the distance between the two arc-shaped positioning posts 23.

[0031] The working principle of this utility model is as follows: First, the initial pressure is set through the touch screen 19. Then, the wheel hub is placed on the placement plate 7 and positioned by the arc-shaped positioning column 23. Then, by operating the touch screen 19, the electric push rod 13 is extended and the pressing plate 16 presses the wheel hub. The pressure sensor 15 monitors the pressure applied by the pressing plate 16. When the pressure of the pressing plate 16 on the wheel hub reaches the set value, the controller 20 controls the electric push rod 13 to stop extending according to the data transmitted by the pressure sensor 15. At this time, the pressure of the pressing plate 16 on the wheel hub will not increase after reaching the set value.

[0032] Then, by operating the touch screen 19, the drive motor 122 drives the elliptical disk 124 to rotate. At this time, the rotating elliptical disk 124 can make the second horizontal plate 11 move up and down repeatedly. Through the up and down moving second horizontal plate 11, the tension of the spring 9 on the ring 8 varies. At this time, the pressure on the wheel hub during the pressure test is constantly changing.

[0033] After the hub has been under pressure for a period of time, the drive motor 122 stops driving the elliptical disk 124 to rotate via the touch display screen 19, and the electric push rod 13 retracts to its initial length. Then, the hub is removed from the placement plate 7, and the hub is observed to see if it is cracked or deformed.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
