[0002] The wheel hub is a cylindrical metal part with the inner contour of the tire supporting the tire and the center mounted on the shaft. It is also called a rim, steel ring, wheel, or tire bell. There are many types of wheel hubs depending on diameter, width, molding method, and material. The wheel hub surface treatment process will also take different methods according to the characteristics and needs of different models. It can be roughly divided into two types: baking paint and electroplating. The appearance of the wheel hub of ordinary models is less considered, and good heat dissipation is a basic requirement. The process basically adopts baking paint treatment, that is, spraying first and then electric baking. The cost is relatively economical and the color is beautiful and lasts for a long time. Even if the vehicle is scrapped, the color of the wheel hub remains unchanged.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-2 In this embodiment, a vehicle wheel hub installation and disassembly device comprises a moving wheel 1, and an adjusting and disassembling mechanism is arranged on the top of the moving wheel 1.

[0021] In this embodiment, the adjusting and disassembling mechanism includes a fixed base 2 fixedly installed on the top of the moving wheel 1, a stepper motor 3 is fixedly installed on the top of the fixed base 2, a threaded rod 4 rotatably connected to the fixed base 2 is fixedly installed on the output shaft of the stepper motor 3, a moving block 5 is threadedly connected to the outer side of the threaded rod 4, a through groove is opened on the top of the fixed base 2, and the moving block 5 is slidably connected to the fixed base 2 through the through groove, which helps the moving block 5 to slide and move inside the fixed base 2.

[0022] Among them, a limit block 6 is fixedly installed at the bottom of the moving block 5 and is slidably connected to the fixed base 2. A limit groove is opened on the top of the fixed base 2. The limit block 6 is slidably connected to the fixed base 2 through the limit groove, which helps to limit the moving block 5 and facilitates stable movement.

[0023] In this embodiment, a moving box 7 is fixedly installed on the top of the moving block 5, and a brake motor 8 is fixedly installed inside the moving box 7. The output shaft of the brake motor 8 is fixedly installed with a bidirectional screw rod 9 that is rotatably connected to the moving box 7. The outer side of the bidirectional screw rod 9 is threadedly connected with two threaded blocks 10. The outer side of the bidirectional screw rod 9 is provided with thread grooves in opposite directions. The thread block 10 is threadedly connected to the bidirectional screw rod 9 through the thread groove, which helps the thread block 10 to move on the outside of the bidirectional screw rod 9.

[0024] Among them, the adjustment and disassembly mechanism also includes a clamping rod 11 fixedly installed on one side of the threaded block 10, a friction pad 12 is provided on the side opposite to the two clamping rods 11, a limiting rod 13 is fixedly installed on the side opposite to the two clamping rods 11, and an auxiliary component is provided on the top of the fixed base 2, and the auxiliary component includes a support rod 14 hinged to the top of the fixed base 2.

[0025] In this embodiment, a pulley 15 is fixedly installed on the other side of the support rod 14 and is slidably connected to the moving box 7. A movable groove is opened on one side of the moving box 7. The pulley 15 is slidably connected to the moving box 7 through the movable groove, which helps the pulley 15 to provide mobile support. A placement frame 16 is fixedly installed on the top of the fixed base 2, and a counterweight block 17 is movably connected to the inner side of the placement frame 16.

[0026] It should be noted that the automobile wheel hub installation and disassembly device, through the setting of the adjustment and disassembly mechanism, uses the brake motor 8 and the bidirectional screw 9 to drive the two clamping rods 11 and the friction pad 12 to fit tightly and apply pressure to the wheel hub, which is helpful to clamp and fix different types of wheel hubs. Using the stepping motor 3 and the threaded rod 4, the moving block 5 can be driven to start moving under the limit of the limit block 6, and the moving block 5 moves to the left on the outside of the threaded rod 4, thereby driving the moving box 7 to move to the left, and driving the moving box 7, the clamping rod 11 and the wheel hub to move to the left in turn. At the same time, the pulley 15 moves upward on the left side of the moving box 7, and the support rod 14 is hinged and rotated at the top of the fixed base 2, so that the wheel hub can be pulled out. Similarly, the wheel hub can be clamped and fixed using the same method, thereby improving the flexibility of the device.

[0027] The working principle of the above embodiment is:

[0028] The automobile wheel hub installation and removal device can first push the fixed base 2 when in use, and the fixed base 2 is moved by the moving wheel 1 to move the device to the wheel hub to be removed, and then continue to push the device to move, insert the two clamping rods 11 into the gap in the middle of the wheel hub, and then start the brake motor 8, the brake motor 8 drives the bidirectional screw rod 9 to rotate, and the two threaded blocks 10 on the outside of the bidirectional screw rod 9 start to move in opposite directions, so that the friction pad 12 fits with the gap in the wheel hub, until the two clamping rods 11 and the friction pad 12 are tightly fitted to the wheel hub and apply pressure, the fixing bolts inside the wheel hub can be removed, and then the stepping motor 3 can be started to drive the threaded rod 4 to rotate, and the moving block 5 on the outside of the threaded rod 4 starts to move under the limit of the limit block 6;

[0029] The moving block 5 moves to the left on the outside of the threaded rod 4, thereby driving the moving box 7 to move to the left, and in turn drives the moving box 7, the clamping rod 11 and the wheel hub to move to the left. At the same time, the pulley 15 moves upward on the left side of the moving box 7, and the support rod 14 is hinged and rotated on the top of the fixed base 2 to pull out the wheel hub. Similarly, the same method can be used to clamp and fix the wheel hub, and drive the wheel hub to move and install, which is convenient to use the brake motor 8 and the two-way screw rod 9, and can drive the clamping rod 11 and the friction pad 12 to be quickly adjusted, which is convenient for clamping and fixing wheel hubs of different sizes, greatly improving the flexibility and practicality of the device.
