AI Technical Summary
Existing tire gripping devices, while ensuring stability during gripping and movement, are prone to over-gripping, leading to tire deformation and consequently affecting the positioning accuracy when releasing the tire.
A car tire gripping device was designed, which uses two cross-shaped mounting plates of different sizes to install an outer gripping clamping plate and an inner gripping clamping plate respectively. Through a clamping drive mechanism and a transmission screw system, the clamping plates are ensured to be misaligned to avoid over-gripping the tire at the same position. Combined with an anti-slip pad, it prevents deformation.
It achieves stable tire gripping, avoids deformation, and ensures accurate subsequent positioning, adapting to the gripping needs of tires of different sizes.
