Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 This embodiment of a wheel hub radial runout online detection and correction integrated machine includes a base 1, a housing 2 fixed to the top of the base 1, two connecting blocks 3 fixed to the inner side of the housing 2, a drive mechanism 4 between the two connecting blocks 3, the drive mechanism 4 penetrating the right side wall of the housing 2, a connecting structure 8 for easy connection on the right side of the drive mechanism 4, a wheel hub 9 on the right side of the connecting structure 8, a lifting component 5 for detecting the radial runout of the wheel hub 9 on the right side of the housing 2 and above the wheel hub 9, a hydraulic cylinder 7 on the top of the base 1, and an electric fan 6 on the inner side of the housing 2.

[0024] In addition, each connecting block 3 has multiple ventilation holes, a dustproof net is fixedly connected to the left side wall of the outer shell 2, and multiple exhaust holes are opened on the top of the outer shell 2. Through the combination of ventilation holes, exhaust holes and dustproof net, a stable flow channel can be provided for air circulation, and the electric fan 6 can be used to stably cool the drive motor 401.

[0025] In addition, the drive mechanism 4 includes a drive motor 401 fixed to two connecting blocks 3. The drive motor 401 is used to provide stable power for the rotation of the hub 9. When using the drive motor 401, the speed of the drive motor 401 needs to be set to a slower speed to ensure that the staff can react in time. One end of the output shaft of the drive motor 401 is fixed with a drive shaft 402 that passes through the right side wall of the housing 2. A support rod is fixed to the top of the base 1. An extension rod is fixed to the right side of the support rod. The drive shaft 402 passes through the support rod and is rotatably connected to the support rod through a bearing.

[0026] In this embodiment, a controller is provided inside the base 1, and a movable door is hinged to the back of the base 1. The controller is electrically connected to the drive motor 401 and signal-connected to the dial indicator 505. The dial indicator 505 can be a digital dial indicator or a dial indicator capable of signal output.

[0027] Please refer to it again. Figures 1 to 3 To improve the flexibility of detection, the lifting assembly 5 in this embodiment includes a support platform 501 fixed to the right side of the outer shell 2. The support platform 501 serves as a connection. A threaded rod 503 is threadedly connected to the inner side of the support platform 501 and passes through the support platform 501. An adjustment plate is fixed to the top of the threaded rod 503. By rotating the adjustment plate, the connecting platform 502 can be lifted and lowered. The outer surface of the threaded rod 503 is rotatably connected to the connecting platform 502 located above the support platform 501 through a bearing. A displacement part 504 is provided on the right side of the connecting platform 502. A dial indicator 505 is fixed to the front of the displacement part 504.

[0028] It is understood that the displacement part 504 includes a support bar 5041 fixed to the right side of the connecting platform 502. A sleeve block 5042 is fitted on the outer surface of the support bar 5041. The support bar 5041 and the sleeve block 5042 are movably connected. The cross-section of the support bar 5041 is rectangular, which can limit the position of the sleeve block 5042. Two threaded plates 5043 are fixed to the back of the sleeve block 5042, and two stabilizing plates 5044 are fixed to the back of the support bar 5041. A rotating rod 5 is rotatably connected between the two stabilizing plates 5044 through a bearing. 045. When the rotating rod 5045 is rotated, the threaded connection between the threaded plate 5043 and the rotating rod 5045 will drive the sleeve block 5042 to move, further realizing the left and right movement of the dial indicator 505. The rotating rod 5045 passes through the right-side stabilizing plate 5044. A turntable 5046 is fixed to the right side of the rotating rod 5045 and outside the stabilizing plate 5044. The rotating rod 5045 passes through two threaded plates 5043 and is threadedly connected to the two threaded plates 5043. Two limiting rods that pass through the support platform 501 are fixed at the bottom of the connecting platform 502.

[0029] Furthermore, hydraulic cylinders 7 are fixed at the bottom of the extension rod and at the top of the base 1. Each of the two hydraulic cylinders 7 is threaded to a pressure block that is compatible with the wheel hub 9. The pressure block can apply pressure to the wheel hub 9 to correct it. The pressure block is a detachable structure that can better adapt to different styles of wheel hubs 9.

[0030] Additionally, the connecting structure 8 includes a connecting shaft 801 extending into and movably connected to the drive shaft 402. Multiple primary sliding keys are fixed to the outer surface of the connecting shaft 801. Multiple primary sliding grooves are formed on the inner side of the drive shaft 402, and the primary sliding keys extend into these grooves respectively. A connecting bolt 802, penetrating both the drive shaft 402 and the connecting shaft 801, is provided at the top of the drive shaft 402. A connecting nut 803 is threaded onto the outer surface of the connecting bolt 802, located below the drive shaft 402. A limiting ring 804 that can limit the position of the hub 9 is fixed on the outer surface of the shaft 801. A snap-fit ​​bracket 805 that passes through the hub 9 is movably connected to the right side of the connecting shaft 801. Multiple secondary sliding keys are fixed on the outer surface of the snap-fit ​​bracket 805. Multiple secondary sliding grooves are opened on the inner side of the connecting shaft 801. The multiple secondary sliding keys extend into the multiple secondary sliding grooves respectively. A limiting bolt 806 that passes through the snap-fit ​​bracket 805 and extends into the drive shaft 402 is provided on the right side of the snap-fit ​​bracket 805. The limiting bolt 806 is threadedly connected to the connecting shaft 801.

[0031] In this embodiment, the detachable design of the connecting structure 8 allows the clip bracket 805 to be replaced according to the needs of different wheel hubs 9. This flexibility greatly improves the adaptability of the equipment, enabling it to adapt to more specifications and types of wheel hubs 9.

[0032] Understandably, the multi-directional adjustment function of the lifting component 5 allows the dial indicator 505 to flexibly contact different parts of the wheel hub 9, expanding the detection range. Compared with the traditional fixed detection method, this adjustable detection method can more comprehensively detect the radial runout of the wheel hub 9.

[0033] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0034] The working principle of the above embodiments is as follows:

[0035] First, start the equipment. The electric fan 6 starts working to cool the drive motor 401 and ensure that the drive motor 401 maintains a stable temperature during operation. According to the specifications of the wheel hub 9 to be tested and calibrated, select a suitable clamping bracket 805 and install the wheel hub 9 onto the clamping bracket 805. Fix the clamping bracket 805 to the connecting shaft 801 with the limiting bolts 806, thereby connecting the wheel hub 9 to the drive shaft 402. After installation, adjust the position of the dial indicator 505 using the lifting assembly 5. After the drive motor 401 starts, the power will drive the wheel hub 9 to rotate continuously. The contacts of the dial indicator 505 will contact the outer surface of the wheel hub 9. As the wheel hub 9 rotates, the dial indicator 505 will measure the radial runout of the surface of the wheel hub 9 in real time. When radial runout occurs, the operator can mark the surface of the wheel hub 9 and then correct it using two hydraulic cylinders 7.
