AI Technical Summary

Technical Problem

In the existing technology, the lack of a limiting structure when the car wheel hub moves on the transmission roller causes the wheel hub to easily deviate from the clamping structure, affecting the accuracy and consistency of the marking position and reducing marking efficiency and quality.

Method used

The system employs a linkage structure of blocking bars and clamping bars, and controls the lifting and adjusting components through a motor-driven gear and pulley system. This enables the hub to automatically block and clamp on the conveyor roller, ensuring the accuracy and stability of the marking position.

Benefits of technology

It improves the uniformity and accuracy of wheel hub marking position, reduces the failure rate, meets the standardized management requirements of mass production, improves marking efficiency, and reduces the failure rate caused by human error.

Abstract

The utility model relates to the field of wheel hub marking, in particular to an automatic marking device for automobile wheel hub unit assembly parameters, which comprises a conveying frame, a conveying roller and a laser marking assembly, two vertical plates are fixedly connected onto the conveying frame, a fixing plate is arranged below the conveying frame, two ends of the fixing plate are fixedly connected onto the two vertical plates respectively, and the laser marking assembly is fixedly connected onto the conveying roller. A stopping rod and two clamping rods are arranged above the fixing plate. According to the utility model, a linkage structure of the blocking rod and the clamping rod is arranged, the motor is used for driving the gear and the belt pulley to synchronously control the lifting assembly and the distance adjusting assembly, automatic blocking and clamping positioning of the hub on the conveying roller are realized, the moving position of the hub can be accurately limited after the blocking rod is lifted, marking deviation caused by excessive conveying is avoided, and the production efficiency is improved. And meanwhile, the clamping rod rapidly clamps the hub through rack transmission, it is ensured that the hub is stable during marking, the uniformity and accuracy of the marking position are remarkably improved, and the problems that manual operation is low in efficiency and high in failure rate are solved.
