Description

Technical Field

[0001] This utility model relates to the field of weld seam milling technology, and more specifically, to a weld seam milling device for an automobile production line. Background Technology

[0002] Automotive production lines require welding workpieces to connect them. Before welding, the weld seam needs to be milled to ensure a strong weld. Existing milling methods using standard machine tools are costly and lack the flexibility to adjust to multiple angles. While 6-axis robots can achieve flexible multi-angle adjustments, they suffer from low precision, slow speed, and high cost. Currently, most milling devices use coolant for cooling, which can cause secondary contamination of the milled product. Weld seam milling devices cannot achieve flexible multi-angle adjustments, cannot mill weld seams at different locations, and lack two sets of milling heads for coordinated operation, affecting milling accuracy.
