Patent number: 11253943Abstract: Provided is a seam welding device capable of seam welding various shapes of objects to be welded. A seam welding device which performs seam welding by causing electricity to be conducted between a first electrode wheel and a second electrode wheel comprises a first motor which drives the first electrode wheel, a second motor which drives the second electrode wheel, and a first belt provided between the first electrode wheel and the first motor. If a direction joining the axes of the first electrode wheel and the second electrode wheel is defined as a vertical direction, the direction from the first electrode wheel toward the second electrode wheel is upward, and the direction from the second electrode wheel toward the first electrode wheel is downward, then the first motor is disposed further upward than a point of contact of the first electrode wheel and the second electrode wheel.Type: GrantFiled: September 26, 2017Date of Patent: February 22, 2022Assignee: HONDA MOTOR CO., LTD.Inventors: Hitoshi Yoshimichi, Hiroshi Miwa

Patent number: 9364882Abstract: A roller hemming device includes a large diameter roller having a large tapered surface and a small diameter roller having a small cylindrical surface. The small diameter roller is coaxially disposed with the large diameter roller. The small diameter roller and the large diameter roller enable to relatively move in an axial direction. The outer diameter of the small cylindrical surface is smaller than the minimum outer diameter of the large tapered surface.Type: GrantFiled: May 8, 2013Date of Patent: June 14, 2016Assignee: HONDA MOTOR CO., LTD.Inventors: Hitoshi Yoshimichi, Hiroshi Miwa, Kazuya Hirose

Patent number: 8819938Abstract: A panel positioning apparatus is provided with an outer panel supporting device 20 adapted to support the outer panel 11 from a lower side of the outer panel 11 and an inner panel supporting device 30 adapted to support the inner panel 12 from an upper side of the inner panel 12. The outer panel supporting device 20 has a lower-surface contact section 23 adapted to abut against a lower surface of the outer panel 11. The inner panel supporting device 30 has an upper-surface contact section 344 adapted to expose below the inner panel 12 and to abut against an upper surface of a part of the outer panel 12 against which the lower-surface contact section 23 abuts. The outer panel 11 and the inner panel 12 are overlaid with each other, and a bending part 112A of the outer panel 11 is bent by pinching the outer panel 11 by the lower-surface contact section 23 and the upper-surface contact section 334.Type: GrantFiled: May 26, 2010Date of Patent: September 2, 2014Assignee: Honda Motor Co., Ltd.Inventors: Eisaku Hasegawa, Nobuhiro Kozasa, Shunsuke Ishii, Hitoshi Yoshimichi, Koki Sanada
