Definitions

  • Lightweight alloy using a lightweight material such as aluminum or magnesium has been widely used in various industrial fields such as civil engineering and construction field and in transportations such as automobiles or airplanes.
  • various industrial fields such as civil engineering and construction field and in transportations such as automobiles or airplanes.
  • the lightweight alloys have to be connected by welding. Accordingly, a technique of welding the lightweight alloy has been widely researched.
  • friction stir welding is disclosed in International Patent Publication document (International Patent No. WO93/10935; applicant: THE WELDING INSTITUTE).
  • the friction stir welding technique will be briefly described with reference to the aforementioned document.
  • two to-be- processed objects are in contact with each other and connected by using friction heat generated while a tool proceeds along the interface between the two objects and using a plastic work phenomenon generated in the objects.
  • the aforementioned friction stir spot welding method is obtained by combining a resistance spot welding method with a friction stir welding method and recognized as another welding method that is different from the friction stir welding.
  • a friction stir spot welding device in which a driver for rotating a main shaft on which a rotation tool is installed in a fixed frame, and the driving shaft of the driver is connected to the spindle of the main shaft through a timing belt or chain, in Japanese Unexamined Patent Application Publication No. 2002-137067 (hereinafter, referred to as 'Kawasaki patent').
  • driving force of the driver is transmitted to the spindle of the main shaft through the timing belt or chain, and accordingly, the main shaft is rotated.
  • the load of the welding device can be reduced as compared with the existing friction stir spot welding device.
  • the load of the friction stir spot welding device can be reduced.
  • the frame 10 has a hollow box shape.
  • first to third plates 12, 14 and 16 are included.
  • the housing 22 protrudes through a lower wall 18 of the frame 10.
  • a rotation tool 24 that is rotated together with the rotation shaft spindle 20 protrudes through the housing 22.
  • the rotation tool 24 allows to-be-processed objects to be connected to each other by applying a predetermined force on a surface of the objects (not shown) while the rotation tool 24 is rotating.
  • the housing 22 does not rotate with the rotation shaft spindle 20 but maintains a fixed state.
  • the power of the rotation shaft driver 30 is transmitted to the rotation shaft spindle 20 through the timing belt or chain 34. Accordingly, the rotation tool 24 is rotated together with the rotation shaft spindle 20.
