[0002] A battery pack refers to a combination of multiple battery cells according to a certain electrical and mechanical structure to form an overall module that can be used for power supply. Later, multiple battery packs need to be assembled and installed in the battery pack shell to achieve electrical connection of multiple battery packs.
[0003] The battery pack shell is an important component of electric vehicles. The battery pack shell is generally a rectangular structure. During production, the shell bottom plate is generally clamped on the welding tooling table, and then the shell sub-plate to be welded is positioned and placed on the shell bottom plate. Then, the shell sub-plate is welded to the shell bottom plate with a welding gun, and finally the battery pack shell is welded. Therefore, the battery pack shell welding tooling is required.
[0004] At present, when welding, the existing battery pack shell welding tool needs to pick up the corresponding shell sub-plate, and the shell sub-plate is mostly placed on the ground, requiring the worker to bend over to pick it up. This action of bending over to pick up the metal shell sub-plate is rather troublesome, which reduces the comfort of the worker on the battery pack shell welding tool to pick up the shell sub-plate in the pre-placed box.
[0005] In addition, the welding tooling tables of the existing battery pack shell welding tools are mostly unable to be horizontally rotated and positioned according to the welding needs of the workers, which reduces the flexibility of the horizontal rotation of the welding tooling tables.

DETAILED DESCRIPTION
[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0027] Reference Figure 1-5 A battery pack shell welding tool includes a welding tool table 1, a shell bottom plate 11 and a clamping cylinder 12 are provided on the welding tool table 1, a clamping plate 13 is provided on the clamping cylinder 12, a tool bottom plate 3 is provided below the welding tool table 1, tool legs 32 are provided on the tool bottom plate 3, a pre-placed material box 5 is provided above the welding tool table 1, and a partition 51 is provided in the pre-placed material box 5;
[0028] A horizontal cylinder 7 and a horizontal slide 30 are provided on the tooling base 3. A guide slide 42 is slidably connected in the horizontal slide 30. A lifting cylinder 4 is provided on the guide slide 42. A lifting rod 41 is provided in the lifting cylinder 4. A cylinder rod 71 is provided on the horizontal cylinder 7. A connecting block 6 is provided on the cylinder rod 71.
[0029] The tooling bottom plate 3 is provided with a side frame plate 2 and an adjusting motor 31 , the side frame plate 2 is provided with a guide sliding side groove 21 , and the tooling legs 32 are provided with a reinforcing rib 33 .
[0030] The connecting block 6 is an L-shaped structure as a whole. The connecting block 6 is fixed to the cylinder rod 71 and the lifting cylinder 4 respectively. When the lifting rod 41 is horizontally extended or retracted left and right, the connecting block 6 can drive the lifting cylinder 4 to slide horizontally along the horizontal slide groove 30 through the guide slide seat 42.
[0031] The upper end of the pre-placement box 5 is open, and there are five partitions 51 arranged horizontally and set in the inner cavity of the pre-placement box 5. Multiple shell sub-plates to be welded can be separated and placed separately in the pre-placement box 5.
[0032] The lifting cylinder 4 and the lifting rod 41 form a group, which are two symmetrical groups in total. The lifting rod 41 is slidably set in the lifting cylinder 4, and the lifting rod 41 is fixed to the pre-placed box 5, which improves the horizontal movement support stability of the upper pre-placed box 5.
[0033] The guide slide 42 is a trapezoidal structure as a whole and is arranged at the lower end of the lifting cylinder 4. The guide slide 42 is slidably engaged with the horizontal slide 30. The guide slide 42 and the horizontal slide 30 are a group, and there are two symmetrical groups in total. The trapezoidal structure ensures that the guide slide 42 slides horizontally along the horizontal slide 30, while preventing the guide slide 42 from slipping out of the horizontal slide 30.
[0034] The motor shaft of the adjusting motor 31 is fixed to the welding tooling table 1, and the side frame plates 2 are two symmetrical ones on the left and right. The top cross-section of the guide sliding side groove 21 is an arc-shaped inner groove structure and is matched with the circular structure welding tooling table 1 for sliding connection, so that the circular structure welding tooling table 1 can be stably rotated and adjusted horizontally along the guide sliding side groove 21.
[0035] The regulating motor 31 is a commonly used servo motor. Through a preset control button, the motor shaft can be rotated forward and reverse at a constant speed and stopped and positioned in real time.
[0036] The reinforcing ribs 33 are triangular in structure as a whole. The reinforcing ribs 33 are fixed to the lower end surface of the tooling base plate 3 and the tooling legs 32 respectively. The triangular structure is highly stable. The reinforcing ribs 33 are made of 12Cr1MoV alloy steel, which has high strength and is not deformed, thereby improving the structural support stability between the tooling legs 32 and the lifting cylinder 4.
[0037] Working method: Place the shell bottom plate 11 on the welding tooling table 1, and then start the clamping cylinder 12 to stably clamp the shell bottom plate 11 through the clamping plate 13. If the current worker is short and has a short arm span, the lifting cylinder 4 can be started to drive the lifting rod 41 to slide downward, thereby realizing the downward movement of the pre-placed box 5. When the pre-placed box 5 drops to a position suitable for the current worker to pick up, the lifting cylinder 4 is stopped, and then the horizontal cylinder 7 is started. The cylinder rod 71 will retract horizontally into the horizontal cylinder 7, thereby driving the guide slide 42 to slide along the horizontal slide 30, driving the pre-placed boxes 5 on both sides to move horizontally and approach. When the distance between the pre-placed boxes 5 on both sides is suitable for the current worker with a shorter arm span, the horizontal cylinder 7 is stopped. At this time, the worker can conveniently and comfortably take the shell sub-plate preset in the pre-placed box 5, which improves the comfort of the worker on the battery pack shell welding tooling to take the shell sub-plate in the pre-placed box 5;
[0038] After taking the housing sub-plate and placing it on the position on the housing bottom plate 11 that needs to be welded, the staff can take a handheld welding gun to perform welding (this is the existing technology).
[0039] In addition, a control button is preset on the adjusting motor 31, and the control button can be used to control the forward and reverse rotation and real-time stop of the motor shaft of the adjusting motor 31, thereby realizing the horizontal forward and reverse rotation and real-time stop of the welding tooling table 1 along the guide sliding side groove 21 at a constant speed, thereby realizing the horizontal forward and reverse rotation and real-time stop positioning of the clamped shell bottom plate 11 according to the welding needs of the staff, thereby greatly improving the horizontal rotation flexibility of the welding tooling table 1.
[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
