摘要： PROBLEM TO BE SOLVED: To provide a friction stir welding apparatus which can improve bonding strength of a bonded member. SOLUTION: During friction stir welding, when a minute shifting means 123 applies a shifting force on an object 17 to be bonded to move it in the Y direction, an articulated robot 100 supporting a base body 21 is deflected by a reaction force given by the object 17 to be bonded, and then the object 17 to be bonded shifts relatively to the base body 21 in the Y direction. As the welding tool 22 shifts in the Y direction together with the base body 21, a bonding zone formed on the object 17 to be bonded can be expanded in the Y direction. Thus, regardless of a size of the welding tool 22, the bonding zone can be expanded to the action direction of the minute shifting means so that the bonding strength of the bonded object 17 can be improved.

摘要翻译：解决的问题：提供一种能够提高接合部件的接合强度的摩擦搅拌接合装置。解决方案：在摩擦搅拌焊接期间，当微小移动装置123对待接合的物体17施加移动力以在Y方向上移动时，支撑基体21的铰接机器人100被反作用力由待粘合的物体17给出，然后待粘合的物体17在Y方向上相对于基体21移动。随着焊接工具22与基体21一起沿Y方向移动，形成在待接合物体17上的接合区域可以沿Y方向扩展。因此，不管焊接工具22的尺寸如何，可以将接合区域扩大到微小移动装置的作用方向，从而可以提高接合物体17的接合强度。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide friction stir welding apparatus that can be miniaturized and that has a profile practical for friction stir welding operation.
SOLUTION: A first chuck body 25 is mounted with a pivoting tool 24 that is freely rotatable while a second chuck body 19 is mounted with a pressurizing tool 27 that is freely linearly displaceable. Friction stir welding is performed by driving the pivoting tool 24 rotatably and the pressurizing tool 27 in a linearly displaceable manner. Since the pivoting tool and the pressurizing tool are independently driven, the tool driving mechanism can be simplified and miniaturized. In addition, there is no need of arranging a rotary motor 28 and a pressure motor 29 together near the second tool holding section 22 in which the pressurizing tool 27 is mounted, thus minimizing the profile near the second tool holding section 22.

摘要： PROBLEM TO BE SOLVED: To provide friction stir welding equipment that stabilizes welding quality of a workpiece by keeping its remaining thickness to a prescribed range. SOLUTION: A distance D3 between tools is acquired and, on the basis of the acquired distance D3 between the tools, the pressurizing force F1 of a welding tool 21 is adjusted and the welding tool 21 is immersed in the workpiece 22 to a position where a target distance D4 is acquired between the tools. Even in the case where a superposed state is not constant between the members 22a, 22b to be welded of the workpiece 22, the immersion quantity can be made constant for the welding tool 21 to be immersed in the workpiece 22. Consequently, the remaining thickness E1 of the workpiece 22 after being welded can be controlled to be a specified value. In addition, abnormality in welding of the workpiece 22 can be prevented, thereby enabling the welding quality to be uniformized. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide an automatic tool exchanger capable of exchanging only tools for friction stir and a tool holder capable of convertibly holding tools by the automatic tool exchanger.
SOLUTION: Using a rotational tool holder 29 having a rotational base mount 40 and an engaged tip as the tool holder, a rotating tool 33 is grasped by press-inserting the rotational base mount 40 and at the same time, the engaged tip is engaged with an engaged portion 48. By this way, the rotating tool 33 can be held only by press-fitting the rotational base mount 40, and if only a directional force to withdraw from the rotational base mount 40 is given to tools, holding is released and separated. Using a tool changer 20 provided with a tool mounting table 75 and a releasing means 76 as the automatic tool exchanger, the releasing means 76 can give a directional force to be released to the rotating tool 33 and the rotating tool 33 withdrawn is received by the tool mounting table 75 for tools.

摘要： PROBLEM TO BE SOLVED: To suppress meandering of wire in a wire supply path between a wire supply means and a contact tip and accordingly stably supply the wire to a laser irradiation point.
SOLUTION: A laser brazing device continuously delivers the wire 12 supplied from a wire supply machine through a guide tube to the irradiation point of a laser beam on a workpiece through the contact tip and fuses the delivery end of the wire 12 by the laser beam. A chuck unit 20 as a meandering suppressing means, which constrains the wire 12 in a radial direction and suppresses the meandering of the wire 12 in the guide tube, is provided at the front step of the contact tip. The chuck unit 20 is configured to have a taper collet 27 which is always urged by a spring 29 and generates fastening force to the wire 12. When the wire 12 is supplied, the taper collet 27 is slightly retreated from a fastening position corresponding to the movement of the wire 12 to allow the free movement of the wire 12.
