AI Technical Summary
The existing bus frame has deformation errors during welding and assembly, which makes it difficult to guarantee dimensional accuracy. Mechanical shaping equipment is inefficient and prone to introducing secondary errors.
The initial deviation is obtained by non-contact scanning measurement. Combined with laser displacement measurement and servo hydraulic drive three-jaw pushing mode, the measurement and data feedback are synchronized in real time. Closed-loop control is achieved through progressive pushing to ensure the accuracy of the skeleton.
It improved the dimensional accuracy and production efficiency of bus frame shaping, reduced secondary errors, and enhanced the quality and smoothness of the entire vehicle manufacturing process.
