一种风机制造用焊接工装
By designing welding fixtures for components such as guide rods, cross plates, slide rails, cylinders, worm gear drives, and indexing plates, the problem of existing welding fixtures being unable to adjust the angle between the impeller and the column was solved. This enabled multi-dimensional and precise docking of the impeller blades and the impeller body, adapting to the welding requirements of different types of fan impellers and improving welding accuracy and efficiency.

AI Technical Summary
The existing welding fixtures cannot adjust the angle between the impeller and the column, which limits their use and makes them unsuitable for welding impellers of different models of fans.
A welding fixture was designed, comprising components such as guide rods, cross plates, slide rails, cylinders, worm gear drives, and indexing plates. The cylinder drives the clamping plate to fix the impeller blades to the C-shaped plate. The welding angle of the impeller blades is adjusted by worm gear drives and angle markings. Combined with stepper motors and limiters, multi-dimensional precise docking is achieved to adapt to the welding requirements of different impellers.
It achieves multi-dimensional and precise docking between the impeller blades and the impeller body, improves welding accuracy and efficiency, adapts to the welding needs of different types of wind turbine impellers, breaks the limitations of traditional tooling, and improves the versatility and applicability of tooling.
