AI Technical Summary
In existing technologies, the welding sequence of excavator track beams is irregular, which leads to difficulties in controlling welding deformation, resulting in out-of-tolerance critical dimensions, low product quality and yield, and an inability to meet the market's demand for high-quality production.
The track beam is divided into three independent units for welding: the travel reducer mounting base, the U-shaped beam assembly, and the guide wheel tensioning device rail. The welding sequence is from the inside to the outside and from the middle to both ends. It is then pressed and fixed by rigid pressure plates. Deformation is controlled by pre-deformation and weight reaction force, reducing the need for correction.
Effectively control welding deformation, improve production quality and yield, reduce correction processes, ensure key dimensions are within tolerance range, and improve production efficiency and structural stability.
