AI Technical Summary

Technical Problem

The existing heavy-duty truck wheel hub bearing rotary press has reduced mechanical positioning accuracy and adaptability when facing bearings and hubs with complex shapes and diverse sizes, resulting in easy offset or misalignment during the press process, affecting the press quality and even causing damage to the bearings or hubs. At the same time, there is a lack of real-time and precise control of the press force and displacement, making it difficult to meet the needs of efficient press installation and intelligent management.

Method used

It introduces a multi-dimensional sensing and positioning module, a multi-modal driving module, an adaptive pressing module, an intelligent diagnosis module and a human-machine collaboration module, and uses laser scanning, pressure sensing and vision guidance technologies for high-precision positioning, realizing force-displacement closed-loop control, providing driving modes that adapt to different working conditions, enhancing the equipment's adaptability and intelligence, and possessing predictive maintenance and remote monitoring functions.

Benefits of technology

It achieves high-precision and high-adaptability positioning of bearings and hubs with complex shapes and various sizes, improves press-fitting quality and efficiency, reduces production costs, enhances equipment reliability and maintenance efficiency, expands the scope of application, and meets the high standards of modern heavy-duty truck manufacturing.
