AI Technical Summary

Technical Problem

Existing welding and positioning tooling for outdoor leisure chairs has problems such as insufficient positioning accuracy, poor adaptability, and low efficiency. Especially when facing different specifications and styles, it leads to poor welding quality, affecting structural strength, safety and appearance consistency.

Method used

A high-precision positioning tooling was designed, which includes a positioning workbench, a sliding support seat, an armrest clamping assembly and a chair back clamping assembly. Through the guide screw, motor drive and flexible clamping structure, the chair leg spacing, armrest position and chair back angle can be precisely adjusted to meet the welding requirements of different shapes and angles.

Benefits of technology

It improves the accuracy and efficiency of welding positioning, reduces manual measurement errors, reduces equipment investment costs, improves the qualified rate of workpieces after welding, and reduces rework rate and raw material waste.

Abstract

The application relates to a high-precision positioning tool for outdoor leisure chair welding, and belongs to the technical field of positioning tools, which comprises a positioning workbench, symmetrical sliding support seats on the positioning workbench slide in the Y-axis direction, a chair leg clamping assembly for clamping chair legs is fixedly installed on one side of the sliding support seat, a fixed seat moving in the X-axis direction is slidably installed on the upper end of the sliding support seat, a handrail clamping assembly that can be lifted in the Z-axis direction is arranged on the fixed seat, a detachable flexible handrail clamping block is arranged in the handrail clamping assembly, and a chair back clamping assembly for clamping and supporting chair backs of different angles is rotatably installed at one end of the fixed seat. Through the transverse guide frame, the guide screw and the guide wheel on the positioning workbench, the sliding support seat slides in the limiting rail, the accurate control of the distance between the chair legs is realized, compared with the traditional manual alignment, the symmetry of the two sides of the leisure chair is ensured, and the stress imbalance caused by the uneven distance is avoided.
