[0003] However, in the prior art, when welding the battery pack shell, the traditional welding tooling cannot fit the battery pack shells tightly together when they are placed, so the workers need to spend extra time and energy to carefully adjust and align the battery packs to ensure that they can fit tightly together. This process is time-consuming and laborious, increasing the difficulty and complexity of the work. In addition, when the battery pack shells cannot fit tightly, the welding quality may be reduced, and even poor welding may occur. Therefore, we provide a welding tool for the power battery pack shell of new energy vehicles. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] The utility model provides a technical solution: Figure 1 - Figure 5As shown, in this embodiment, a welding tool for the shell of a power battery pack of a new energy vehicle comprises: a positioning mechanism 1, the positioning mechanism 1 comprises a cylinder 11, the cylinder 11 is docked in a slot opened on one side of the top of an operating table 31, a telescopic rod 12 is arranged at one end of the cylinder 11, a slide rail 13 is arranged in the operating table 31, and movable plates 14 are arranged at both ends of the top of the slide rail 13, the output end of the cylinder 11 is docked with the telescopic rod 12, the outer surface of the slide rail 13 is fixedly connected to the inner wall of the operating table 31, and the end of the telescopic rod 12 away from the cylinder 11 is fixedly connected with the movable plate 14, the bottom sides of the two movable plates 14 are respectively slidably connected to the top of the slide rail 13, and the opposite sides of the two movable plates 14 are respectively docked with the two ends of the blind 33, and the opposite sides of the two movable plates 14 are respectively provided with adjustment plates 15, and the two ends of the two movable plates 14 away from the adjustment plate 15 are provided with three adjustment grooves 16, and the adjustment grooves 16 are provided with adjustment members 17. A rack 18 is provided at the bottom of the opposite side of the two movable plates 14, one end of the adjusting member 17 passes through the adjusting groove 16 and is threadedly connected to the inner wall of the thread groove opened on the side of the adjusting plate 15 close to the movable plate 14, the bottom of the opposite side of the two movable plates 14 is fixedly connected with the rack 18, a fixing bar 19 is provided in the slide rail 13, a fixing member 110 is provided in the card groove opened at the center of the fixing bar 19, two ends of the fixing bar 19 are respectively fixedly connected to the two sides of the inner wall of the slide rail 13, a fixing member 110 is fixedly connected in the card groove opened at the center of the fixing bar 19, a bearing 111 is provided on the outer surface of the fixing member 110, a gear 112 is provided on the outer surface of the bearing 111, the outer surface of the top of the fixing member 110 is fixedly connected to the inner surface of the bearing 111, the outer surface of the bearing 111 is fixedly connected to the inner surface of the gear 112, the teeth of the two racks 18 are meshed with the tooth grooves of the gear 112, and a buffer mechanism 2 is provided on the top of the adjusting plate 15.

[0025] In this embodiment, when the staff uses the device to position weld multiple battery panel shells, they first place the battery pack shell on the operating table 31, and drive the telescopic rod 12 to drive the movable plate 14 to move on the slide rail 13 by starting the cylinder 11. When the movable plate 14 moves, the rack 18 will also keep moving synchronously, and then one tooth of the rack 18 will mesh with the tooth groove of the gear 112, so the gear 112 will rotate. During the rotation of the gear 112, the tooth groove on the other side of the gear 112 will mesh with the tooth of the other rack 18, so the two movable plates 14 will keep synchronous relative horizontal movement, and then the battery on the operating table 31 The battery pack shell will be positioned and clamped and fit tightly together. At the same time, the curtain 33 will be retracted or stretched due to the synchronous movement of the two movable plates 14. The curtain 33 can prevent external dust and debris from falling into the workbench and causing difficulty in cleaning. When the battery pack to be positioned and clamped is shorter, the adjustment member 17 can be rotated counterclockwise to release the limit fixation between the adjustment plate 15 and the movable plate 14. When the adjustment plate 15 is adjusted downward to a suitable position, the adjustment plate 15 and the movable plate 14 are again limited and fixed by the adjustment member 17 to ensure that the buffer plate 25 can fit more fully with the battery pack shell, which helps to improve welding quality and reduce welding defects.

[0026] like Figure 1 - Figure 5 As shown, the buffer mechanism 2 includes a connecting block 21, the bottom of which is fixedly connected to a slot opened at the top of the adjusting plate 15, one side of the connecting block 21 is fixedly connected to a fixed tube 22, a movable rod 23 is slidably connected inside the fixed tube 22, the other end of the movable rod 23 passes through the inner ring of a buffer spring 24 and is fixedly connected to one side of a buffer disk 25, one end of the buffer spring 24 is fixedly connected to one end of the fixed tube 22 away from the connecting block 21, and the other end of the buffer spring 24 is fixedly connected to a side of the buffer disk 25 close to the movable rod 23.

[0027] In this embodiment, when the two movable plates 14 move relative to each other to position and clamp the battery pack shell, the buffer plate 25 will first contact the outside of the battery pack shell. When the buffer plate 25 then squeezes the battery pack shell, the movable rod 23 will slide into the inside of the fixed tube 22. The spring will be squeezed and deformed by the squeezing force generated when the buffer plate 25 moves toward the side of the fixed tube 22. The resulting buffering effect can better protect the battery pack shell from deformation of its appearance under squeezing and clamping.

[0028] The utility model provides a new energy vehicle power battery pack shell welding tool, the specific working principle is as follows:

[0029] When the staff needs to use the device to perform precise positioning welding on multiple battery panel shells, they first need to place the battery pack shell on the operating table 31. When the cylinder 11 is started, it will push the telescopic rod 12. After the telescopic rod 12 is pushed, the movable plate 14 will move on the slide rail 13. In this process, the rack 18 will also keep moving synchronously. When the rack 18 moves, one of its teeth will mesh with the tooth groove of the gear 112, and the gear 112 will rotate. During the rotation of the gear 112, the tooth groove on the other side of the gear 112 will mesh with the teeth of the other rack 18. Therefore, the two movable plates 14 will maintain synchronous relative horizontal movement, so that the battery pack shell on the operating table 31 will be positioned and clamped, and fit tightly. Together, at the same time, the curtain 33 will be retracted or stretched due to the synchronous movement of the two movable plates 14. When the height of the battery pack to be positioned and clamped is relatively short, the adjusting member 17 can be rotated counterclockwise to release the limit fixation between the adjusting plate 15 and the movable plate 14, and then, when the adjusting plate 15 is adjusted downward to a suitable position, the adjusting plate 15 and the movable plate 14 are again limited and fixed by the adjusting member 17. When the two movable plates 14 move relative to each other to position and clamp the battery pack shell, the buffer plate 25 will first contact the outside of the battery pack shell. When the buffer plate 25 then squeezes the battery pack shell, the movable rod 23 will slide into the inside of the fixed tube 22. At this time, the spring will be squeezed and deformed by the extrusion force generated when the buffer plate 25 moves toward one side of the fixed tube 22.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
