is a clamper such as an electromagnet, 3 and 3 are blank,
() Place the blanks 3, 3 on the clampers 2, 2 and press them against the rising positioning plate 1 to position and fix the blanks 3, 3 on the clampers 2, 2 (see Figure 1), Next, the positioning plate 1 is lowered (see A in Fig. 1), and then the clampers 2, 2 are brought relatively close together by the thickness of the positioning plate 1, and the welded parts of the blanks 3, 3 are butted (see A in Fig. 1). (see B in FIG. 1), and then the welded portion of the blank 3 is welded by laser welding or the like (see C in FIG. 1).

た。 In the welding positioning device, spatters 4 adhere to the lowered positioning plate 1 during welding as shown in FIG. 1 (see FIG. 2), and the positioning plate 1
When the plate rises again and positions the next blank 3, 3, this spatter 4 adheres to the abutting surface of the blanks 3, 3 (see Fig. 3), and the positioning plate 1 descends to position the next blank 3, 3. When the two blanks 3 are butted together, the blanks 3 come into contact with each other through the spatters 4, which increases the butt gap (see FIG. 4) and causes welding defects.

を供する点にある。 The present invention addresses the above-mentioned problems, and includes a welding positioning device that includes a positioning plate that can be raised and lowered to position the blank when it is raised, and a clamper that clamps the positioned blank by pressing against the positioning plate. The welding positioning device is characterized in that protrusions are provided on both sides of the positioning plate against which the blank is pressed, and the front surface of the protrusions is used as a reference surface for positioning. The object of the present invention is to provide an improved welding positioning device that does not cause welding defects.

がある。 The welding positioning device of the present invention is constructed as described above.
Positioning plate 1 placed on top of 2 and rising
The blanks 3, 3 are positioned and fixed on the clampers 2, 2 by pressing against the ridges 1a, and then the positioning plate 1 is lowered. The clampers 2, 2 are brought relatively close to each other by a thickness of 1), the welded portions of the blanks 3, 3 are butted, and welded by laser welding or the like. However, during positioning, the blanks 3, 3 come into contact with the narrow protrusion 1a of the positioning plate 1, as described above, and the possibility of the spatter 4 adhering to the blank 3 is extremely small, resulting in poor welding. This has the effect of preventing as much as possible.
