DEVICE FOR SWEEP-GRINDING/POLISHING/CLEANING FILLET WELDING ZONE

摘要

PROBLEM TO BE SOLVED: To grind/polish/clean a weld bead face as well as a lower plate face and a vertical plate face which are adjacent to the weld bead face by a single sweep-grinding mechanism. SOLUTION: A single grinding/polishing/cleaning mechanism 26 with which the weld bead 4 at the fillet welding zone on a lower plate 2 and a vertical plate 1 as well as each of the steel plate faces of the lower plate 2 and the vertical plate 1 which are adjacent to the weld bead 4 are simultaneously ground/polished/cleaned is formed in a way that the mechanism can be pressed against the fillet welding zone while keeping a predetermined angle by a pressing mechanism 27. An elevating/lowering mechanism 30 which elevates and lowers both of the grinding/polishing/cleaning mechanism 26 and the pressing mechanism 27 is provided.
