AI Technical Summary

⚠Technical Problem

Existing internal support clamps have complex drive and transmission structures, occupy a large space, and are costly. The synchronization of multiple support legs is difficult to guarantee precisely, which may lead to uneven force on the wheel hub and tilting. There is a lack of effective positioning and detection methods, resulting in unstable clamping and surface damage.

⚗Method used

A gripper for gripping the outer rim of an automobile wheel hub was designed. It consists of a bracket, chassis, drive unit, and inner support assembly. The drive unit drives the inner support assembly to move radially. Combined with slider and linkage transmission, the synchronous movement of multiple inner support assemblies is achieved. Sensors are used for positioning detection, and cylinders are used as drive units to improve stability and accuracy.

🎯Benefits of technology

The fixture is adaptable to wheel hubs with different inner diameters, improving production flexibility and efficiency, avoiding damage to the outer surface of the wheel hub, enhancing the stability and precision of clamping, and reducing mechanical vibration.
