Description
環状の溶接部位を溶接するための治具は、溶接部位に対応した開口部を設ける必要があるため、環状の内側と外側とで治具が分離してしまう。
溶接部位が互いに近接している場合には、近接している溶接部位の間に取り付ける治具の寸法が小さくなることで治具の強度が低下し、その結果として、治具による溶接部位周辺の溶接部品の保持が不十分になってしまっていた。また、溶接部位が非常に近接している場合には、このような溶接部位の間に治具が配置できない場合もある。溶接部位に治具を配置できない場合には、溶接部位周辺の溶接部品の保持がさらに不十分になってしまっていた。
まず、本発明の溶接用治具装置の実施の形態について説明する。
図1は、本発明の実施の形態に係る溶接用治具装置1の概略構成を示すための、正面図である。図2は、溶接用治具装置1の一方側治具10及び他方側治具20の概略構成を示すための、平面図である。図3は、溶接用治具装置1の一方側治具10の部分平面図である。図4は、溶接用治具装置1の他方側治具20の部分底面図である。図5は、溶接用治具装置1の一方側治具10及び他方側治具20のA-A断面図である。図6は、溶接用治具装置1により製造される部品5の概略構成を示すための、平面図である。
治具架台部30は、一方側支持部31と、他方側支持部32と、一方側支柱33と、他方側支柱34と、支持台35とを備える。
