Detailed Description

As shown in fig. 1, the utility model discloses an electric core flexible coupling laser welding's auxiliary fixtures, including the carrier plate 7 of the rectangle that a level was placed, be equipped with the second constant head tank 5 that supplies flexible coupling 10 location to place and supply the first constant head tank 2 that the core 9 location was placed on the last edge of carrier plate 7. The battery cell 9 and the flexible connection 10 are positioned through the first positioning groove 2 and the second positioning groove 5 and then welded through welding equipment, and welding quality is guaranteed.

The both sides of 7 length direction of carrier plate are equipped with vertical flange 6 respectively, and the middle part of carrier plate 7 is equipped with along 7 width direction's of carrier plate horizontal flange 4 that distribute, and vertical flange 6 and horizontal flange 4 adopt casting or machining mode integrated into one piece with carrier plate 7. And two ends of the transverse rib 4 are respectively provided with a second positioning groove 5 for positioning and placing the flexible connection 10. The first positioning groove 2 is enclosed on the carrier plate 7 on both sides of the transverse rib 4 by the longitudinal rib 6 and the corresponding side of the transverse rib 4. The end of the first positioning groove 2 far away from the transverse rib 4 is open and distributed, and the open end of the first positioning groove 2 is provided with a longitudinal positioning mechanism 1 for pushing the battery cell 9 in the first positioning groove 2 to the transverse rib 4 so as to realize the positioning and placement of the battery cell 9.
