AI Technical Summary

Technical Problem

In the existing technology, once the bolt seat is welded to the wheel hub, it is difficult to remove it from the fixed fixture, resulting in problems such as inaccurate positioning and poor welding consistency.

Method used

An auxiliary tooling for welding inner ring bolt seats of wheels has been designed, including a lifting platform, a rotating platform, a clamping component, an abutting component, and a pushing component. Through the coordinated action of the pushing component, clamping component, abutting component, elastic locking block, and receiving groove, automatic clamping and unlocking are achieved to ensure accurate positioning and stable locking of the bolt seat. It also automatically unlocks after welding is completed, making it convenient to remove the wheel hub.

Benefits of technology

It improves the automation level and production efficiency of welding, solves the technical problem of difficult removal of workpieces after welding, ensures welding consistency and stability, and enhances the adaptability and versatility of tooling.

Abstract

The application relates to the technical field of wheel production, and particularly discloses an auxiliary tool for welding a bolt seat of a wheel inner ring, which comprises a lifting table and a rotating table, the table top of the lifting table and the table top of the rotating table are concentrically arranged, a clamping piece, an abutting piece and a pushing piece are installed on the rotating table, the pushing piece is used for pushing the clamping piece and the abutting piece to slide along the radial direction of the rotating table, the clamping piece comprises a mounting table and upper and lower clamping jaws, the abutting piece is provided with an abutting ring, elastic pieces two are arranged between the abutting ring and the rotating table, elastic pieces one are arranged between the clamping piece and the pushing piece, and elastic locking blocks for limiting the movement of the abutting ring towards the center of the rotating table are installed on the rotating table; when the wheel hub is removed, the clamping jaws are separated from the bolt seat and abut against the bolt seat through the abutting piece, so that the welding stability of the bolt seat is not affected when the wheel hub is removed.
