[0002] Automobile wheels are an important part of automobile parts. With the growth of China's automobile parts industry, the wheel industry has gradually developed and grown. The wheels on the market can be divided into steel wheels and alloy wheels according to the material. The main advantage of steel wheels is the simple manufacturing process. Steel wheels are generally made by casting, which is a process in which the metal is in a molten state and is gradually cooled or crystallized under pressure to form the wheel. There are many burrs on the surface of the wheel after forming, and the burrs on the surface of the wheel need to be polished. When polishing the automobile wheel, it is necessary to use an automobile wheel clamping tool to stably clamp the automobile wheel.

[0003] Existing automobile wheel hub clamping devices usually use a two-point clamping method to clamp and fix the two sides of the automobile wheel hub during the clamping process. However, due to the arc-shaped and smooth surface of the outer side of the automobile wheel hub, this clamping method is not stable. During the processing of the automobile wheel hub, the automobile wheel hub may become loose, thereby affecting the processing efficiency of the automobile wheel hub. Utility Model Content

[0036] Example 3

[0037] See also Figure 5 、 Figure 6 and Figure 7This embodiment provides a technical solution: a vehicle wheel hub clamping device, comprising a movable base 1 and a clamping portion 2:

[0038] A plurality of guide grooves 206 are provided on the side of the transmission column 205, and guide columns 208 are provided on both sides of the sliding block 207. There are six guide grooves 206, and the guide columns 208 are embedded in the guide grooves 206 and are connected to the transmission column 205. The guide columns 208 can slide along the guide grooves 206 by sliding the transmission column 205 up and down, thereby controlling the sliding block 207 to slide along the slide groove b204. There are six sliding blocks 207, and the six sliding blocks 207 are rotationally symmetrical around the axis of the sliding column 202. The side of the sliding block 207 is provided with an inclined surface, and the sliding displacement of the six sliding blocks 207 can control the sliding displacement of the sliding block 207. The automobile wheel hub can be quickly and firmly fixed on the sliding column 202. When the transmission column 205 is not subjected to external force, the spring b210 pushes the transmission column 205 to move upward in the slide groove a203, so that the guide column 208 slides to the bottom of the guide groove 206. At this time, the six sliding blocks 207 all slide out of the slide groove b204 and expand outward. When the transmission column 205 is subjected to downward pressure, the transmission column 205 overcomes the elastic force of the spring b210 and slides downward in the slide groove a203, so that the guide column 208 slides to the top of the guide groove 206. At this time, the six sliding blocks 207 all slide along the slide groove b204 to the inside of the sliding column 202 for storage.

[0039] Working principle: First, when fixing the automobile wheel hub, align the center hole of the wheel hub at the center of the automobile wheel hub with the top of the sliding column 202 and press down. At this time, the bottom of the center hole of the wheel hub will abut against the inclined surface of the top of the six sliding blocks 207, thereby pushing the six sliding blocks 207 to slide along the slide groove b204 to be stored inside the sliding column 202. When the center hole of the wheel hub passes through the six sliding blocks 207, the spring b210 pushes the transmission column 205 to move up in the slide groove a203, so that the guide column 208 slides to the bottom of the guide groove 206. At this time, the six sliding blocks 207 all slide out of the slide groove b204 and expand outward. While pressing the automobile wheel hub downward, the bottom of the automobile wheel hub will abut against the push plate 211. When the six sliding blocks 207 pop out again, the automobile wheel hub is released, and the elastic force provided by the spring a209 is used. , which can push the push plate 211 to slide upward along the slide column 202, so that the sliding block 207 that slides outward and the push plate 211 that slides upward can be clamped, so that the automobile wheel hub can be quickly and firmly fixed on the slide column 202, thereby improving the processing efficiency of the automobile wheel hub. After the automobile wheel hub is processed, by pressing the transmission column 205 downward, the transmission column 205 overcomes the elastic force of the spring b210 and slides downward in the slide groove a203, so that the guide column 208 slides to the top of the guide groove 206. At this time, the six sliding blocks 207 all slide along the slide groove b204 to the inside of the slide column 202 for storage. At this time, since there is no sliding block 207 on the top of the automobile wheel hub, the automobile wheel hub will move upward under the drive of the spring a209 to push the push plate 211, making it convenient for the operator to take it out.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
