[0002] The wheel hub refers to the component on the vehicle where the wheel is mounted, usually made of metal. It is the connecting part between the wheel and the vehicle, bearing the weight of the vehicle and allowing the wheel to rotate freely through bearings. The wheel hub usually has a circular shape with a hole in the middle for mounting the axle on the vehicle. On some high-performance vehicles, the wheel hub may also have a more complex design to increase the stability and handling performance of the vehicle.

[0003] After casting, existing wheel hubs still need to undergo other finishing operations, such as deburring, chamfering and other fine operations, and positioning is required for fine processing; for these wheel hubs that can be installed with hub covers, existing positioning fixtures usually squeeze the two ends of the wheel hub for positioning; this positioning method is not only inaccurate in positioning, but also easily causes damage to the tire mounting area of ​​the wheel hub, thereby affecting the quality of the wheel hub. Therefore, the utility model provides a wheel hub disassembly assembly device to meet the needs. Utility Model Content

[0012] Compared with the prior art, the present invention has at least the following beneficial effects:

[0013] In the above solution, the design of the limit assembly not only enables precise fixation of wheels of different specifications, but also, because the fixing method is from the inside to the outside, that is, the fixing parts apply the fixing force from the inside to the outside of the wheel hub.

In particular, it protects the wheel hub edge and the key parts for tire installation, ensuring the integrity and quality of the wheel hub. The fixing method from the inside to the outside allows the fixing parts to be more evenly distributed on the inside of the wheel hub, providing more stable support and fixing effect.

In addition, the triangular structure formed by the inclined rod, the fixing part and the extension rod further enhances the stability of the fixing part.

[0015] In the above solution, the inclination of the lifting plate can be adjusted through the design of the lifting component, thereby facilitating the removal and installation of the wheel hub. This design not only improves work efficiency, but also reduces the difficulty of operation, making the entire process more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] A wheel hub disassembly assembly device provided by the present invention is described in detail below with reference to the accompanying drawings and specific embodiments. At the same time, it is explained here that, in order to make the embodiments more detailed, the following embodiments are preferred embodiments, and for some well-known technologies, those skilled in the art may also adopt other alternatives.

[0023] like Figures 1 to 4As shown, the embodiment of the present invention provides a wheel hub disassembly assembly device, including a device frame 1, a lifting plate 2 is provided inside the device frame 1, and a connecting disc 3 is fixedly connected to the top of the lifting plate 2; a lifting component, the lifting component is used to adjust the inclination of the lifting plate 2, the lifting component is connected to the device frame 1, a device cavity 101 is opened inside the top of the device frame 1, and a rotating shaft 102 is fixedly connected to both sides of the inner cavity of the device cavity 101, and a fixing sleeve is fixedly connected to one side of the bottom of the lifting plate 2, and the two fixing sleeves are fixedly connected to the bottom of the lifting plate 2. Rotatingly connected to the outside of the two rotating shafts 102 respectively, the lifting assembly includes a lifting motor 103 fixedly connected to the bottom of the inner cavity 101 of the device, a lifting screw 104 fixedly connected to the output shaft of the lifting motor 103, the external thread of the lifting screw 104 is connected to the transmission block 105, the top of the transmission block 105 is rotatably connected to the support plate 106, and the other end of the support plate 106 is rotatably connected to the other side of the bottom of the lifting plate 2; first, start the lifting motor 103 fixedly connected to the bottom of the inner cavity of the device cavity 101. The start of the lifting motor 103 is the starting power source for the entire lifting process. As the lifting motor 103 is started, its output shaft will drive the lifting screw 104 to start rotating. The rotation of the lifting screw 104 is the key to the lifting plate 2 being able to move up and down. The external thread of the lifting screw 104 is connected to the transmission block 105. When the lifting screw 104 rotates, the transmission block 105 will move up and down along the screw. The top of the transmission block 105 is rotatably connected to a support plate 106, and the other end of the support plate 106 is rotatably connected to the other side of the bottom of the lifting plate 2. Therefore, as the transmission block 105 moves up and down, the support plate 106 will push the lifting plate 2 to adjust the inclination accordingly. Since one side of the bottom of the lifting plate 2 is rotatably connected to the rotating shaft 102 at the top of the device frame 1 through a fixed sleeve, and the other side is connected to the transmission block 105 through the support plate 106, when the transmission block 105 moves up and down, the lifting plate 2 will rotate around the rotating shaft 102, thereby adjusting the inclination. The lifting assembly can achieve precise adjustment of the inclination of the lifting plate 2. This precise adjustment helps to put the wheel hub in the best working position when removing or installing the wheel hub, improving the accuracy and efficiency of the operation. The automated design of the lifting assembly reduces the tediousness and labor intensity of manual operation and improves work efficiency. The operator only needs to start the lifting motor 103 to achieve automatic tilt adjustment of the lifting plate 2. The lifting assembly has a reasonable structural design and the connections between the various components are firm and reliable, ensuring the stability and safety of the lifting plate 2 throughout the lifting process. This helps prevent accidents when removing or installing the wheel hub, protecting the safety of operators and equipment. The design of the lifting assembly enables it to adapt to wheel hub removal assembly devices of different specifications and models. By adjusting the inclination of the lifting plate 2, it can adapt to the removal requirements of wheel hubs of different heights and angles, improving the versatility and flexibility of the device.

[0024] like Figures 1 to 4As shown, the limit assembly is used to fix wheel hubs of different specifications. The limit assembly is connected to the connecting disc 3. The limit assembly includes a rotating motor fixedly connected to the bottom of the connecting disc 3. The rotating disc 4 is fixedly connected to the output shaft of the rotating motor. There are four connecting members 401 distributed in a circle on the outside of the rotating disc 4, and the inside of each connecting member 401 is rotatably connected to a rotating plate 402. The other end of the rotating plate 402 is rotatably connected to an extension rod 303. The other end of the extension rod 303 is fixedly connected to an arc-shaped fixing member 304. The top of the connecting disc 3 is fixedly connected to a support ring 301. The rotating disc 4 is located at the center of the support ring 301. Four circular equidistantly distributed limit posts 302 are fixedly connected to the top of the rotating disc 4. A limit slot is provided inside the rotating plate 402. The limit posts 302 are slidably connected to the inside of the limit slot. There are four square slots, and each square slot is located directly below an extension rod 303. A guide rod is provided inside the square slot. The bottom of the extension rod 303 is fixedly connected to a sliding plate 306, which is slidably connected to the outside of the extension rod 303. The bottom end of the sliding plate 306 is rotatably connected to a roller 307. The bottom of the connecting disc 3 is located below the square slot and is fixedly connected to a limit frame 308. The bottom of the inner cavity of the limit frame 308 is provided with a rolling groove for the rolling of the roller 307. The fixing part 304 is provided with hard rubber on the outside, and an inclined rod 305 is fixedly connected to the other side of the fixing part 304. The bottom end of the inclined rod 305 is fixedly connected to the top of the extension rod 303. The inclined rod 305, the fixing part 304 and the extension rod 303 form a stable triangular structure. First, place the wheel hub on the top of the limit assembly and start the rotating motor connected to the bottom of the connecting disc 3. The start of the rotating motor will drive the rotating disk 4 on its output shaft to begin rotating. The rotation of the rotating disk 4 will drive the four rotating plates 402 to rotate synchronously through the connecting member 401. Each rotating plate 402 is slidably connected to the limiting post 302 at the top of the rotating disk 4 through an internal limiting groove, ensuring stability and accuracy during the rotation process. As the rotating plate 402 rotates, the extension rod 303 rotatably connected to it will also move accordingly. Because the bottom of the extension rod 303 is fixedly connected to the sliding plate 306, the sliding plate 306 slides within the rolling groove of the limiting frame 308 via the roller 307. This design makes the movement of the extension rod 303 smoother and more stable. As the extension rod 303 moves, the arc-shaped fixing member 304 fixed to its end will gradually approach and contact the inner side of the wheel hub. Since hard rubber is provided on the outer surface of the fixing part 304, this soft material can effectively reduce damage to the surface of the hub and increase friction to ensure the fixing effect. The other side of the fixing part 304 is fixedly connected to the top of the extension rod 303 through the inclined rod 305. The inclined rod 305, the fixing part 304 and the extension rod 303 together form a stable triangular structure.This structural design not only enhances the supporting force of the fixing part 304, but also improves the stability and durability of the entire limiting assembly. Through the continuous adjustment of the rotating motor and the coordinated work of the rotating plate 402, the extension rod 303 and the fixing part 304, the limiting assembly can accurately fix the wheels of different specifications and shapes. The hard rubber design on the fixing part 304 effectively reduces the damage to the wheel surface, especially avoids the problems such as extrusion deformation that may be caused by traditional clamps. The design of the triangular structure and the sliding connection of the roller 307 in the rolling groove make the entire limiting assembly more stable and reliable when fixing the wheel hub. The limiting assembly can be flexibly adjusted according to the specifications and shapes of the wheel hub, and is suitable for a variety of different types of wheel hub fixing needs.

[0025] The working principle provided by the present invention is as follows: first, the wheel hub is placed on top of the limiting assembly, and the rotary motor connected to the bottom of the connecting disc 3 is started. The starting of the rotary motor will drive the rotating disc 4 on its output shaft to start rotating, and the rotation of the rotating disc 4 will drive the four rotating plates 402 to rotate synchronously through the connecting member 401. Each rotating plate 402 is slidably connected to the limiting column 302 on the top of the rotating disc 4 through an internal limiting groove, ensuring stability and accuracy during the rotation process. As the rotating plate 402 rotates, the extension rod 303 connected to it will also move accordingly. Since the bottom of the extension rod 303 is fixedly connected to the sliding plate 306, the sliding plate 306 slides in the rolling groove of the limiting frame 308 through the roller 307. This design makes the movement of the extension rod 303 smoother and more stable. As the extension rod 303 moves, the arc-shaped fixing member 304 fixed at its end will gradually approach and contact the inner side of the wheel hub. Because the outer surface of the fixing member 304 is provided with hard rubber, this soft material can effectively reduce damage to the wheel hub surface and increase friction to ensure the fixing effect. The other side of the fixing member 304 is fixedly connected to the top of the extension rod 303 through the inclined rod 305. The inclined rod 305, the fixing member 304 and the extension rod 303 together form a stable triangular structure. This structural design not only enhances the supporting force of the fixing member 304, but also improves the stability and durability of the entire limit assembly. Through the continuous adjustment of the rotating motor and the coordinated work of the rotating plate 402, the extension rod 303 and the fixing member 304, the limit assembly can accurately fix wheels of different specifications and shapes. Then, the lifting motor 103 fixedly connected to the bottom of the inner cavity of the device cavity 101 is started. The start of the lifting motor 103 is the starting power source of the entire lifting process. As the lifting motor 103 is started, its output shaft will drive the lifting screw 104 to start rotating. The rotation of the lifting screw 104 is the key to the lifting plate 2 being able to move up and down. The external thread of the lifting screw 104 is connected to the transmission block 105. When the lifting screw 104 rotates, the transmission block 105 will move up and down along the screw. The top of the transmission block 105 is rotatably connected to the support plate 106, and the other end of the support plate 106 is rotatably connected to the other side of the bottom of the lifting plate 2. Therefore, as the transmission block 105 moves up and down, the support plate 106 will push the lifting plate 2 to adjust the inclination accordingly. Since one side of the bottom of the lifting plate 2 is rotatably connected to the rotating shaft 102 at the top of the device frame 1 through a fixed sleeve, and the other side is connected to the transmission block 105 through the support plate 106, when the transmission block 105 moves up and down, the lifting plate 2 will rotate around the rotating shaft 102, thereby achieving adjustment of the inclination. The lifting assembly can achieve precise adjustment of the inclination of the lifting plate 2. This precise adjustment helps to put the wheel hub in the best working position when disassembling or installing the wheel hub, improving the accuracy and efficiency of the operation.

[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
