[0002] Tires are an important part of cars, and usually clamps are used to grab them. Tires can be fixed in a specified position by clamping or adsorption. Human assistance is required during the installation process. Although automated equipment plays an important role in automobile production lines, manual assistance is necessary to install tires in some cases. In addition, some small automobile manufacturers or hand-made cars may still use manual tire installation methods. In this case, workers need to use tools and skills to perform installation work.

[0003] When installing tires on cars, tires of different specifications and sizes may differ, and loose clamping may occur during the gripping process. If a tire falls off and needs to be reinstalled, additional assembly efficiency will be increased, and the wheel hub of the fallen tire is also prone to wear. Therefore, we propose a tire positioning and gripping device to ensure that the tire can be gripped accurately. Utility Model Content
