ADJUSTMENT AID AND LASER WELDING DEVICE

To provide an adjustment aid and a laser welding device capable of quantifying deviation of an actual focal position relative to a focal position in a layout.SOLUTION: An adjustment aid is mounted on a laser emission side of a galvano scanner, and is used for adjusting a tool coordinate system of a galvano scanner. The adjustment aid includes: a light receiving member having a light receiving surface that is at least one plane; and a coupling member for coupling the light receiving member to the galvano scanner, and capable of oppositely arranging the light receiving surface at a laser emission port of the galvano scanner at a prescribed distance. The light receiving member has a light receiving sign part, on the light receiving surface, for quantifying a difference of a relative position of an actual light receiving position of light emitted from the laser emission port, relative to a reference light receiving position of the light emitted from the laser emission port.SELECTED DRAWING: Figure 1 【課題】設計上の焦点位置に対して実際の焦点位置のずれを定量化することが可能な調整補助具及びレーザ溶接装置を提供すること。【解決手段】ガルバノスキャナのレーザ出射側に装着されて、ガルバノスキャナのツール座標系を調整するのに用いられる調整補助具であって、少なくとも１つの平面である受光面を有する受光部材と、受光部材をガルバスキャナに連結する連結部材であって、ガルバノスキャナのレーザ出射口に受光面を所定の距離を空けて対向配置可能な連結部材と、を備え、受光部材は、受光面に、レーザ出射口から出射する光の基準受光位置に対する、レーザ出射口から出射する光の実際の受光位置の相対位置の差を定量化するための標示である受光標示部を有する。【選択図】図１
