It relates to a joining device.
- the present invention is suitable for spot joining a plurality of superposed metal members.
- a friction stir welding method (hereinafter referred to as FSW) for joining by frictional heat generated between a welding tool and a workpiece is known, and is described in, for example, Patent Document 1.
- FSW is a method in which the workpiece is softened by frictional heat between the welding tool and the workpiece, and the plastic flow is caused by the rotation of the welding tool. , For example, based on a principle different from the arc welding method.
- a spot bonding method applying the principle of FSW is also known, and is described, for example, in Patent Documents 2 and 3.

And a welding tool rotation axis conversion device for inclining the rotation axis of the welding tool with one point in the rotation axis direction of the welding tool as a fulcrum.
- the joining method of the present invention does not move the joining tool continuously along the joining line, the backing member is compared with a normal FSW construction method in which the joining tool is moved continuously. It is easy to press, and is suitable for joining curved objects. In addition, compared with the conventional spot bonding, the region to be metal-bonded can be widened, and the bonding strength can be increased.

- the size of the joining device is about 1000 mm in height, about 600 mm in width, and about 30 mm in thickness (in the direction perpendicular to the paper).
- 1 is a joining tool
- 2 is a joining tool rotating motor
- 3 is a frame
- 4 is a workpiece
- 5 is a hammer
- 6 is a Stono
- 7 is a spring
- 8 is a guide column
- 9 is a joining head up / down moving motor
- Reference numeral 10 denotes an object holder
- 11 denotes a spring
- 12 denotes a belt
- 13 denotes a welding head swing shaft
- 14 denotes a welding head
- 15 denotes a welding head base plate
- 21 denotes a workpiece support.
- the welding head 14 includes a welding tool 1, a welding tool rotating motor 2, an object holder 10, a welding head base plate 15, and the like.
- the welding tool driving device includes a welding head vertical movement motor 9, a belt 12 for transmitting the rotational force of the motor to a ball screw (not shown), and the rotation of the ball screw. And a guide column 8 for guiding the joining head moving.
- the welding head 14 is configured such that the welding tool rotation axis can be inclined in the direction of arrow 22 shown in FIG. 1 with the welding head swing axis 13 as a fulcrum.
- the spring 7 connects the joining tool rotating motor 2 and the joining head base plate 15, and the joining head 14 does not rotate unless an external force acts on it.
- the lower end of the workpiece holder 10 is located closer to the workpiece 4 than the lower end of the welding tool 1. For this reason, the lower end of the workpiece holder 10 comes into contact with the workpiece 4 first when the welding head 14 is lowered. Since the workpiece holder 10 is attached to the welding head base plate 15 via the spring 11, the workpiece holder 10 comes into contact with the workpiece and then the welding head 14 descends. The object holder 10 keeps a state of elastic contact with the object 4 due to the expansion and contraction of the spring. As a result, the workpiece holding member 10 acts to hold the workpiece 4 with a predetermined force that does not damage the workpiece 4.
