SCRIBING TOOL

To make it possible to entry a scribe line on a surface of a structure while achieving reduction of work time and workload by use of a contact type three-dimensional measuring instrument.SOLUTION: A scribing tool, which is combined with a contact type three-dimensional measuring instrument provided with a probe having a spherical tip, comprises: a fixation part which is detachably fixed to a surface of a work-piece which is an intermediate product during manufacture of a structure; and a probe reception part which holds the tip of the probe, and positions the probe along the surface of the work-piece. A punch insertion hole, which extends along a direction perpendicular to the surface of the work-piece in the state that the fixation part is fixed to the surface of the work-piece, is provided.SELECTED DRAWING: Figure 1 【課題】接触式３次元測定器を用い、作業時間及び作業負担の軽減を図りながら、構造物の表面に罫書き線を記入可能にする。【解決手段】罫書き用治具は、球状の先端部を有するプローブが設けられた接触式３次元測定器と組み合わせられる罫書き用治具であって、構造物の製造途中の中間品であるワークの表面に着脱自在に固定される固定部と、プローブの先端部を保持すると共にプローブをワークの表面に沿って位置決めするプローブ受部と、を備え、固定部がワークの表面に固定された状態において、ワークの表面に垂直な方向に沿って延びるポンチ挿入孔が設けられている。【選択図】図１
