AI Technical Summary

Technical Problem

In the existing welding process of box-type substation shells, the workpiece clamping is unstable, the plate position is offset, and the welding deformation is difficult to control. Traditional tooling is not capable of multi-face clamping and angular positioning, resulting in poor welding quality and high labor intensity, and it is difficult to meet the requirements of high repeatability positioning accuracy.

Method used

Welding positioning fixtures, including a base, horizontal limiting module, longitudinal limiting module and side wall limiting unit, are adopted. Through the coordinated action of multiple limiting modules, rapid positioning, precise limiting and stable clamping of the box-type substation shell are achieved. Combined with servo motor and magnetic/chuck structure, the posture stability and position accuracy during the welding process are ensured.

Benefits of technology

It significantly improves welding accuracy and quality, reduces reliance on manual experience, shortens preparation time, enhances clamping stability and angle consistency, and ensures high efficiency and precision in the welding process.

Abstract

This invention relates to the field of substation welding technology, specifically to a welding positioning fixture and welding equipment for a box-type substation shell; comprising: a base with a vertically fixed guide; a horizontal limiting module horizontally disposed on the base with its rear end slidingly engaged with the guide; two sets of first longitudinal limiting modules, the two sets of first longitudinal limiting modules being disposed opposite each other on both sides of the base; each longitudinal limiting module includes a guide frame, an adjusting frame capable of horizontally approaching and moving away from the substation shell, and a side wall limiting unit flipped and disposed outside the adjusting frame; and a second longitudinal limiting module vertically slidably disposed on one side of the guide frame with its limiting end perpendicularly facing the substation shell; this invention not only enables multi-directional limiting of the substation shell but also allows for precise adjustment of the limiting angle, with high adjustment accuracy and good correction effect.
