[0016] Specifically, the motherboard 50 (B-pillar plate) is clamped and positioned on the inner support frame 20 by the motherboard positioning component 30, and the position of the motherboard positioning component 30 changes with the shape of the motherboard 50 (B-pillar plate), so it can be used for motherboards 50 (B-pillar plates) of different shapes; the patch plate 60 is supported and positioned on the lower surface of the motherboard 50 (B-pillar plate) at the position to be spot welded by the patch plate positioning component 40, and the position of the patch plate positioning component 40 changes with the shape of the patch plate 60, so it can be used for patch plates 60 of different shapes. When spot welding different patch plates 60, it is not necessary to change the new fixture, thus improving the spot welding efficiency of the patch plate.

[0017] Furthermore, after the patch plate 60 is positioned on the lower surface of the main board 50 (B-pillar plate) to be spot welded, the patch plate 60 is spot welded to the lower surface of the main board 50 (B-pillar plate) using a spot welding machine, thereby increasing the local strength of the main board 50 (B-pillar plate).

The first positioning block 31, the second positioning block 32, the third positioning block 33, and the positioning plate 34 surround the motherboard 50 and clamp and position the motherboard 50 on the rectangular frame. The inner support frame 20 has grooves on its surface corresponding to the positions of the first positioning block 31, the second positioning block 32, the third positioning block 33, and the positioning plate 34. The bottom of the first positioning block 31, the second positioning block 32, the third positioning block 33, and the positioning plate 34 is equipped with sliders corresponding to the grooves. The positions of the first positioning block 31, the second positioning block 32, the third positioning block 33, and the positioning plate 34 can be slid along the grooves, thereby adjusting the positions of the first positioning block 31, the second positioning block 32, the third positioning block 33, and the positioning plate 34 according to the shape of the main board 50. This allows the first positioning block 31, the second positioning block 32, the third positioning block 33, and the positioning plate 34 to surround and clamp the main board 50. Locking bolts are threaded on the first positioning block 31, the second positioning block 32, the third positioning block 33, and the positioning plate 34. After the first positioning block 31, the second positioning block 32, the third positioning block 33, and the positioning plate 34 move to the corresponding positions, the positions are fixed by the locking bolts.

[0020] Specifically, after the motherboard 50 is placed on the inner support frame 20, the motherboard 50 is surrounded and fixed by the first positioning block 31, the second positioning block 32, the third positioning block 33 and the positioning plate 34, thereby positioning the motherboard 50 on the inner support frame 20.

[0021] The positioning plate 34 has a positioning post 35 at its end that mates with the edge of the motherboard 50. The positioning post 35 supports and positions the motherboard 50 from one end of the motherboard 50.

[0022] The patch plate positioning assembly 40 includes a first support plate 41, a second support plate 42, a third support plate 43, a first support rod 44, a second support rod 45, and a fourth support plate 47.

The first support plate 41, the second support plate 42, the third support plate 43, the first support rod 44, the second support rod 45, and the fourth support plate 47 surround the patch plate 60 and support and position the patch plate 60 on the lower surface of the main board 50 at the position to be spot welded.

[0023] The inner support frame 20 has grooves on its surface corresponding to the positions of the first support plate 41, second support plate 42, third support plate 43, first support rod 44, second support rod 45, and fourth support plate 47. Sliding blocks corresponding to the grooves are installed on the first support plate 41, second support plate 42, third support plate 43, first support rod 44, second support rod 45, and fourth support plate 47, allowing the first support plate 41, second support plate 42, third support plate 43, first support rod 44, second support rod 45, and fourth support plate 47 to slide along the grooves. This adjusts the positions of the first support plate 41, second support plate 42, third support plate 43, first support rod 44, second support rod 45, and fourth support plate 47 according to the shape of the patch plate 60. The positions of the support rod 45 and the fourth support plate 47 allow the first support plate 41, the second support plate 42, the third support plate 43, the first support rod 44, the second support rod 45, and the fourth support plate 47 to surround and clamp the patch plate 60, positioning the patch plate 60 on the lower surface of the main board 50 at the spot welding position. Locking bolts are threaded onto the first support plate 41, the second support plate 42, the third support plate 43, the first support rod 44, the second support rod 45, and the fourth support plate 47. After the first support plate 41, the second support plate 42, the third support plate 43, the first support rod 44, the second support rod 45, and the fourth support plate 47 move to their corresponding positions, their positions are fixed by the locking bolts.

[0024] Specifically, after the motherboard 50 is placed on the inner support frame 20, it is fixed by the first positioning block 31, the second positioning block 32, the third positioning block 33 and the positioning plate 34. The patch plate 60 is placed on the lower side of the motherboard 50 and is clamped and fixed by the first support plate 41, the second support plate 42, the third support plate 43, the first support rod 44, the second support rod 45 and the fourth support plate 47, so that the patch plate 60 is positioned on the lower surface of the motherboard 50 at the position to be spot welded.

[0025] A third support rod 46 is slidably mounted on one long side of the rectangular frame. The end of the third support rod 46 is equipped with a rubber pad, which contacts the lower surface of the patch plate 60. A groove is formed on the surface of the inner support frame 20 corresponding to the position of the third support rod 46. A slider corresponding to the groove is mounted on the third support rod 46, allowing it to slide along the groove. This adjusts the position of the third support rod 46 according to the shape of the patch plate 60, ensuring that the end of the third support rod 46 contacts the lower surface of the patch plate 60 through the rubber pad. The third support rod 46 supports the patch plate 60, ensuring it adheres to the lower surface of the main board 50. A locking bolt is threaded onto the third support rod 46, securing it in place after it moves to the corresponding position.

[0026] The outer frame 10 has guide rollers 11 rotatably mounted on both sides at equal intervals. The spot welding fixture is slidably mounted on the spot welding workbench via the guide rollers 11, which facilitates the adjustment of the position of the spot welding fixture.

[0027] Working principle: In use, the main board 50 is fixed by the first positioning block 31, the second positioning block 32, the third positioning block 33 and the positioning plate 34, thereby positioning the main board 50 on the inner support frame 20; and the patch plate 60 is clamped and fixed by the first support plate 41, the second support plate 42, the third support plate 43, the first support rod 44, the second support rod 45 and the fourth support plate 47, so that the patch plate 60 is positioned on the lower surface of the main board 50 to be spot welded. At the same time, the patch plate 60 is supported by the third support rod 46 to ensure that the patch plate 60 can be attached to the lower surface of the main board 50. Then, the patch plate 60 is spot welded to the lower surface of the main board 50 (B-pillar plate) by a spot welding machine, thereby increasing the local strength of the main board 50 (B-pillar plate).
