AI Technical Summary

Technical Problem

Traditional fixture structures obstruct the welding path of the inner cavity and outer edge of the wheel hub, which restricts the movement of the welding robot arm, poses an interference risk, and introduces repeated positioning errors through multiple clamping, making it difficult to achieve simultaneous processing of inner and outer welds, thus reducing production efficiency and welding accuracy.

Method used

The axially through hollow alignment fixture structure, combined with a positioning component that can deflect over a large span and a synchronous control structure, enables adaptive clamping and rotation of the wheel hub semi-ring prefabricated part. Through independent control of the drive component and transmission system, unified positioning and synchronous rotation of three references are achieved, avoiding motion interference and repeated positioning errors.

Benefits of technology

This technology enables seamless welding of the inner and outer weld seams of the wheel hub, improving production efficiency and welding precision, ensuring consistency of the three reference standards, reducing errors caused by repeated clamping, and enhancing overall welding quality and automated cycle efficiency.

Abstract

This invention relates to the field of industrial production technology, specifically to an intelligent laser welding system for wheel hub processing. It includes two symmetrically arranged alignment fixtures; each fixture comprises a support frame, a push frame, and a clamping seat with an axially through-hole hollow structure. A positioning component driven by a gear ring is provided in the clamping area. The positioning component drives the clamping component via a deflection arm to achieve adaptive clamping of the inner wall or outer edge of the wheel hub semi-ring preform. Simultaneously, two sets of transmission components are provided for clamping drive and rotation drive, respectively, and synchronous operation of the two fixtures is achieved through a synchronous shaft. Combined with a displacement component, the two wheel hub semi-ring preforms are axially aligned and their end faces are fitted together. This invention can achieve unified positioning of the center hole, outer circle, and end face under a single clamping condition, and realize stable synchronous rotation of the wheel hub and continuous welding on both inner and outer sides. It effectively avoids welding path interference and repeated clamping errors, improving welding accuracy, structural consistency, and overall production efficiency.
