AI Technical Summary
In the existing technology, the lack of a dedicated combination fixture in the welding process of motorcycle or electric vehicle handlebars leads to inaccurate positioning of multiple fixed support components, resulting in large cumulative errors and low welding accuracy and efficiency.
A combined clamping device is designed, comprising a riser positioning mechanism, a handle positioning mechanism, a first fixing clamping mechanism, a second fixing clamping mechanism, and a third positioning clamping mechanism. These mechanisms enable synchronous positioning and clamping of the riser and handle with the same reference, ensuring the precise positioning of multiple fasteners.
It improved welding accuracy and efficiency, reduced cumulative errors from repeated positioning, and increased the product qualification rate.
