Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a positioning device for positioning a welded part in welding equipment for butt welding two welded parts.

[0002]

[Prior Art]

 When two welded parts (1) and (2) are butted and continuously welded like TIG welding or laser welding, as shown in FIGS. 3 and 4, one welded part (hereinafter, fixed side welded part) is used. (1) is set in the positioning jig (3) by an appropriate means, and the other welding part (hereinafter referred to as the moving side welding part) (2) is placed close to the positioning jig (3). It is moved to the fixed side welding part (1) by the feeding means (4) such as a roller or a pusher, and the end surface of the moving side welding part (2) is pressed against the end surface of the fixed side welding part (1) and abutted, Weld the abutting points.

During the above welding, if the fixed-side welded part (1) and the movable-side welded part (2) are both thin plates and easily bendable, the movable-side welded part (2) is pressed against the fixed-side welded part (1). When applied, the impact is large and the moving-side welded component (2) may ride on the fixed-side welded component (1) or be deformed. In particular, as shown in Fig. 5, when the welding part (2) on the moving side was fed in at an angle, it almost climbed up and welding was not possible.

As a solution to the above problems, there is one disclosed in Japanese Utility Model Laid-Open No. 60-34394. As shown in FIG. 6, a positioning plate (6) is provided at a central portion of a positioning table (5) so that the positioning plate (6) can be moved up and down, and a fixed side welding part (1) and a moving side are provided on both sides of the positioning plate (6). The welded parts (2) are butted against each other, and then the positioning plate (6) is released as shown in FIG. 7 so that the moving side welded parts (2) are butted against the fixed side welded parts (1). ing.

[0005]

[Problems to be solved by the device]

 The above means requires a positioning plate (6) and a lifting means for moving it up and down, which complicates the structure and increases the manufacturing cost.

Further, even if the inclination of the moving-side welding component (2) is corrected by the positioning plate (6), the moving-side welding component (2) is fixed to the fixed-side welding part after the positioning plate (6) escapes. When I pressed it to (1), I sometimes got on it.

The present invention aims to provide a positioning device capable of reliably abutting a moving-side welded part on a fixed-side welded part.

[0008]

[Means for Solving the Problems]

 This invention is an apparatus for butt-positioning two welded parts, and a positioning jig for positioning and fixing the periphery of one welded part (fixed-side welded part) and a positioning jig arranged and positioned in the positioning jig. And a magnet for magnetizing the welded part, and the other welded part (moving side welded part) is attracted to the magnetized welded part (fixed side welded part).

[0009]

[Action]

 The positioning device configured as described above positions the fixed-side welded component on the positioning jig, magnetizes the fixed-side welded component with the electromagnet, and attracts the moving-side welded component to the magnetized fixed-side welded component and abuts them. It was done like this.

Since the moving-side welded component is attracted to the fixed-side welded component in this manner, the moving-side welded component does not move over the fixed-side welded component after it abuts on the fixed-side welded component, and is reliably positioned.

[0011]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

As shown in FIG. 1, the positioning device includes a positioning jig (10) for positioning the fixed-side welded part (1) and an electromagnet (11) for magnetizing the fixed-side welded part (1). It is equipped.

In the positioning jig (10), holding metal fittings (12) for holding the peripheral edge of the fixed-side welding component (1) are arranged on three sides, and the respective holding metal fittings (12) (12) ... Positioning is fixed by pressing the three peripheral edges of (1).

The electromagnet (11) is placed in the positioning jig (10) and comes into contact with the lower surface of the positioned fixed-side welded component (1) to energize the fixed-side welded component (1). Magnetize.

The above-mentioned positioning device supplies the fixed-side welding component (1) to the positioning jig (10) by an appropriate conveying means and sets it in the holding metal fittings (12) (12). Next, the electromagnetic stone (11) is energized, and the moving-side welding component (2) is sent to the fixed-side welding component (1) side by the conveyor (13).

When the moving-side welded part (2) approaches the fixed-side welded part (1) to some extent, the movable-side welded part (2) is attached to the magnetized fixed-side welded part (1) as shown in FIG. They are attracted and matched.

In the positioning device, since the moving-side welded part (2) is pulled toward the fixed-side welded part (1) and abutted against each other, the moving-side welded part (2) once abuts against the fixed-side welded part (1). Then, since the external force for moving the moving-side welded part (2) does not act thereafter, the moving-side welded part (2) does not ride on the fixed-side welded part (1). Further, even if the moving-side welded component (2) is inclined, it can be satisfactorily struck because it is pulled in order from the closer side and abutted.

The electromagnet (11) may be arranged on the upper surface side of the fixed-side welded component (1).

[0019]

[Effect of the device]

 According to this invention, the moving-side welded part is attracted to the fixed-side welded part and abutted against each other, so that the moving-side welded part does not ride on the fixed-side welded part and deformation does not occur. You can do it. Further, it is only necessary to assemble the electromagnet in the positioning jig, and a feeder mechanism such as a roller or a pusher for pushing the moving-side welded parts is not required, and the positioning device can be simplified.
