[0022] like Figure 1 As shown, the battery 1 to be cast-welded includes a battery container 11, and a pre-grooved pole group 12 is provided in the battery container 11. The pole group 12 is pre-grooved to a certain extent, but not to the bottom, so that at this time, the pole ears 13 on the positive and negative plates in the pole group 12 protrude from the battery container 11, so as to be used for cast welding to form a busbar. After the cast welding is completed, the pole group 12 is further grooved to the bottom.

[0023] like Figures 1 to 3 As shown, a battery cast welding height level calibrable device includes a cast welding base membrane 2 and a cast welding position plate 3.

[0024] The top surface of the cast welding bottom membrane 2 has a cast welding cavity 21, and the cast welding bottom membrane 2 is lowered below the molten lead in the lead pot, so that the molten lead enters the cast welding cavity 21, and then the pole ear extends into the cast welding cavity 21, and the lead liquid is cooled to form a bus.

[0025] The cast welding position plate 3 has a positioning groove 31 for cooperating with the battery slot 11 of the battery to be cast welded for positioning. The outer periphery of the mouth of the battery slot 11 has a circle of step structure, which is used for the battery slot 11 to cooperate with the battery cover. During cast welding, this circle of step structure just cooperates with the positioning groove 31 to position the battery slot 11.

[0026] The cast welding position plate 3 is provided with a plurality of limit pins 33, the lower ends of which extend out from the bottom surface of the cast welding position plate 3, and the cast welding bottom film 2 is provided with positioning holes 22 for the limit pins 33 to extend into for positioning. The positioning holes 22 are through holes that penetrate the cast welding bottom film 2, so that after the cast welding bottom film 2 is immersed in the lead liquid and lifted up, the lead liquid can flow out of the positioning holes 22 smoothly to avoid blocking the positioning holes 22.

[0027] The number of the limiting pins 33 can be selected as needed, and it is only necessary to ensure that the cast welding position plate 3 and the cast welding bottom membrane 2 are positioned in the horizontal direction. Therefore, the number of the limiting pins 33 is at least one on each side, and preferably, the limiting pins 33 include four located at the four corners of the cast welding position plate 3.

[0028] The lower end of the limiting pin 33 is a pointed tip, which plays a guiding role when the limiting pin 33 is inserted into the positioning hole 22. The limiting pin 33 is detachably fixed to the cast-welded position plate 3, so that it is convenient to replace the limiting pin 33 after it is damaged. The upper end of the limiting pin 33 has a fixing portion 34, and the fixing portion 34 is a truncated cone with a small upper portion and a large lower portion. Correspondingly, the cast-welded position plate 3 is provided with a truncated cone-shaped mounting hole that matches the fixing portion 34. The upper end surface of the fixing portion 34 is provided with a first threaded hole, and the limiting pin 33 is fixed to the cast-welded position plate 3 by a fixing bolt 35. The fixing bolt 35 includes a stud portion and a nut portion, and the stud portion of the fixing bolt 35 is threadedly matched with the first threaded hole, and the nut portion of the fixing bolt 35 abuts against the top surface of the cast-welded position plate 3. When the fixing bolt 35 is tightened, the nut portion abuts against the top surface of the cast welding position plate 3, thereby exerting an upward pulling force on the limiting nail 33, so that the fixing portion 34 and the truncated cone-shaped mounting hole on the cast welding position plate 3 are tightly fitted and fixed.

[0029] The cast welding position plate 3 is provided with a plurality of balancing pins 32, which pass through the cast welding position plate 3 and have their bottom ends abutting against the top surface of the cast welding bottom film 2 when in use. The number of balancing pins 32 can be selected as needed, and it is only necessary to ensure that the cast welding position plate 3 and the cast welding bottom film 2 maintain a set spacing. Therefore, the number of balancing pins 32 is at least one on each side, preferably four at the four corners of the cast welding position plate 3. The limiting pins 33 at each corner of the cast welding position plate 3 are located on the outside of the balancing pins 32.

[0030] The balancing nail 32 is preferably configured to be adjustable in length so as to be adjusted as required, thereby making the distance between the cast welding position plate 3 and the cast welding base film 2 adjustable.

[0031] In the structure shown in the figure, the balancing pin 32 has a threaded section, the threaded section has an external thread, the cast welding position plate 3 is provided with a second threaded hole matched with the threaded section, and the threaded section is matched with a locking nut 36 in the area above the cast welding position plate 3. The length of the bottom extending out of the second threaded hole is adjusted by rotating the balancing pin 32, and the locking nut 36 is tightened after the adjustment is completed.

[0032] When the battery cast welding height level calibrable device of the present application is in use, the battery 1 to be cast welded is turned upside down and positioned with the positioning groove 31 on the cast welding position plate 3, and then the cast welding bottom film 2 is extended into the lead pot and immersed in the lead liquid, so that the lead liquid fills the cast welding cavity 21. After the cast welding bottom film 2 is raised, the mold is hung to remove the excess lead liquid on the surface of the cast welding bottom film 2, and then the cast welding position plate 3 is positioned with the cast welding bottom film 2, so that the limit pin 33 is extended into the positioning hole 22, and the bottom surface of the balance pin 32 is against the top surface of the cast welding bottom film 2. At this time, the pole ear 13 of the battery 1 is extended into the lead liquid in the cast welding cavity 21. After the cast welding bottom film 2 is cooled, the lead liquid in the cast welding cavity 21 forms a bus, and the cast welding is completed.

[0033] In the battery cast welding height horizontal calibrable device of the present application, the limit pins on the cast welding position plate extend into the positioning holes on the cast welding bottom film. The limit pins only play a role in horizontal positioning, while in the vertical direction, the balance pins on the cast welding position plate are pressed against the top surface of the cast welding bottom film to achieve positioning. This prevents conventional limit pins from sticking lead and causing deviations in cast welding height, which affects the quality of cast welding. At the same time, adjustable balance pins are provided. According to the actual deformation of the cast welding bottom mold or the cast welding position plate, the limit pins are appropriately adjusted to ensure the consistency of the cast welding battery height and the quality of battery cast welding.
