[0033] like Figure 1-4 It can be seen that the embodiment of the utility model provides a tool for disassembling square aluminum shell batteries, including a base 10, a limit assembly 20 and a cutter assembly 30.

[0034] A longitudinal guide rail 13 is provided on the base 10;

[0035] The limiting assembly 20 includes a base 21 mounted on the longitudinal guide rail 13 and a screw rod 22 mounted on the base 21. The base 21 has a first opening groove 214 and a screw hole 211 penetrating the top wall of the base 21 at the lower end thereof. One end of the screw rod 22 passes through the screw hole 211 into the first opening groove 214, and an adjusting rod 23 is mounted on the other end thereof for rotating the screw rod 22.

[0036] The cutter assembly 30 includes a fixed seat 31 and a tension spring 32 installed at one end of the fixed seat 31. A cutter 33 is installed at the other end of the fixed seat 31 for cutting square aluminum shell batteries. The fixed seat 31 is slidably installed in the first opening groove 214. The end of the screw 22 away from the adjusting rod 23 can abut against the fixed seat 31 for adjusting the height of the cutter 33. The tension spring 32 is sleeved on the outside of the screw 22, and the end away from the cutter 33 is fixed on the inner wall of the top wall of the base 21. When the tension spring 32 recovers, it can drive the cutter 33 to reset.

[0037] The embodiment of the utility model sets a limit assembly 20. When cutting square aluminum shell batteries of different models and sizes, the screw 22 abuts against the fixing seat 31. The feed amount of the screw 22 on the limit assembly 20 is adjusted by rotation to control the height of the cutter 33 during the cutting process, so that the cutting depth of the cutter 33 can be controlled, so as to avoid the cutting depth of the cutter 33 affecting the disassembly effect and causing damage to the battery cell. The embodiment of the utility model also sets a tension spring 32. After the cutting is completed, the screw 22 rotates back to the initial position. The return of the tension spring 32 can drive the cutter 33 to reset, which is convenient for users to use, improves operating efficiency, and enhances the convenience and applicability of the tool. The utility model sets a limiter to effectively control the cutting depth of the cutter 33, so that the tool can meet the disassembly requirements of square aluminum shell batteries of different models and sizes, facilitates the different use requirements of users, and improves the disassembly efficiency of square aluminum shell batteries.

[0038] like Figure 1It can be seen that in an optional embodiment of the present utility model, the base 10 includes two relatively arranged transverse guide rails 12 and a limit plate 11 fixed on the transverse guide rails, and the longitudinal guide rail 13 is slidably installed on the transverse guide rail 12. The limit plate 11 and the longitudinal guide rail 13 are located on one side and are used to limit the position of the square aluminum shell battery.

[0039] Specifically, by setting a limit plate 11, the limit plate 11 and the longitudinal guide rail 13 are placed on one side to limit the position of the square aluminum shell battery, so that the cut square aluminum shell battery can be accurately positioned, avoiding the square aluminum shell battery being placed too deep to affect the cutting effect, and ensuring that the square aluminum shell battery will not move or shake unnecessarily during disassembly or processing. This setting helps to maintain the accuracy and safety of the operation, and can ensure the controllability and stability when performing related work. It should be noted that the limit plate 11 is fixed on the base 10 to share the pressure on the base 10 during cutting, making the square frame structure of the base more stable, extending the service life of the device, and ensuring the stability and practicality of the device.

[0040] like Figure 1 It can be seen that in an optional embodiment of the present invention, a supporting assembly is also provided in the base 10, and the supporting assembly includes an elastic member 15 and an abutment member 14 connected to one end of the elastic member 15, and the other end of the elastic member 15 is installed on the inner wall of the base 10, and the abutment member 14 and the adjacent two side plates of the square frame form an adjustable square mold cavity for fixing the square aluminum shell battery.

[0041] Specifically, by setting a support assembly, a square mold cavity with adjustable spacing is formed between the abutment member 14 on the support assembly and the side plate of the base 10. When cutting square aluminum shell batteries of different models and sizes, the adjustable design makes the process of fixing the square aluminum shell battery more flexible and simple, improves the adaptability of the tool, and is suitable for batteries of various specifications. The combination of the elastic member 15 and the abutment member 14 can provide sufficient elastic force to ensure that the square aluminum shell battery can be firmly and firmly fixed in the square mold cavity to prevent it from shaking or loosening during operation, thereby improving the versatility and practicality of the tool, meeting the different usage requirements of different users, and improving the user experience. It should be noted that the elastic member 15 is a spring, and the design of the spring helps to alleviate the impact or vibration between the battery and the support assembly, plays a buffering role, and helps to protect the outer shell of the square aluminum shell battery from damage.

[0042] like Figure 1It can be seen that in an optional embodiment of the present utility model, the longitudinal track includes two sliders 131 slidably mounted on the transverse guide rail 12 and two cross bars 132 fixed on the sliders 131, and two through holes 213 are provided on the base 21, and the through holes 213 are located on both sides of the first opening groove 214. The cross bars 132 are arranged through the through holes 213, and the base 21 slides on the longitudinal guide rail 13.

[0043] Specifically, by setting a longitudinal track, the base 21 can slide on the longitudinal track. Under the limiting action of the through hole 213 and the cross bar 132, the base 21 can move in a directional manner on the longitudinal track, so that the base 21 can be stable on the longitudinal track, avoiding the base 21 from shaking or moving due to force during the cutting process, and ensuring the stability and stability of the cutter 33 during the sliding process. This design provides a convenient sliding adjustment function, making the adjustment of the equipment more convenient and faster, reducing the complexity of manual operation, and facilitating the position adjustment and positioning of the working parts.

[0044] like Figure 2 and Figure 3 It can be known that in an optional embodiment of the present utility model, a moving handle 24 is further provided on the base 21 , and the moving handle 24 is fixed to the outer wall of the base 21 for pushing the base 21 to move.

[0045] Specifically, by providing the movable handle 24, it is convenient for the user to apply force to the base 21, providing a more convenient control method. The provision of the movable handle 24 enables the operator to easily control the position of the base 21 and more conveniently adjust the working position of the tool. At the same time, it can reduce sharp or protruding parts and reduce the risk of accidental injury to the operator during operation.

[0046] like Figure 3-8 It can be known that in an optional embodiment of the present utility model, the first opening groove 214 is an opening groove with openings at both ends, and two movable notches 212 are provided on the two inner walls of the first opening groove 214. The length direction of the movable notch 212 is the same as the axial direction of the screw 22. Two limit pins 311 are fixed on the two outer walls of the fixed seat 31. The limit pins 311 extend into the movable notches 212 to limit the moving position of the fixed seat 31.

[0047] Specifically, by setting two movable notches 212 in the first opening groove 214, two limit pins 311 on the fixed seat 31 extend into the movable notches 212, and the limit pins 311 can move along the axial direction of the screw 22 in the movable notch 212, limiting the moving position of the fixed seat 31, so that the cutting knife 33 has a limited cutting depth range, avoiding excessive movement or shaking of the fixed seat 31 during cutting, and ensuring that it remains stable during operation to avoid damaging the battery cell, thereby increasing the stability of the fixed seat 31 and improving the reliability and safety of the equipment. The first opening groove 214 is an opening groove with openings at both ends, providing a movable space for the fixed seat 31. This design makes it easier to disassemble and assemble the fixed seat 31 from the base 21, improving the convenience of work and operating efficiency.

[0048] like Figure 5 and Figure 6 It can be seen that in an optional embodiment of the present utility model, two parallel second opening grooves 215 are provided on the two inner walls of the first opening groove 214, and the length direction of the second opening groove 215 is perpendicular to the length direction of the movable notch 212. One end of the second opening groove 215 is connected to the movable notch 212, and the other end is connected to the outer wall of the base 21 for installing the limit pin 311.

[0049] Specifically, by providing the second opening slot 215, one end of the second opening slot 215 is connected to the movable notch 212, and the other end is connected to the outer wall of the base 21, forming a connected channel, when installing the fixed seat 31, the limit pin 311 can be easily installed in the movable notch 212, avoiding breaking or bending during the installation process, affecting the activity of the fixed seat 31, facilitating the removal and installation of the fixed seat 31, and improving the applicability of the tool. The installation of the limit pin 311 enhances the stability of the fixed seat 31, and helps to ensure that the fixed seat 31 remains in the desired position when moving.

[0050] In an optional embodiment of the present invention, the outer diameter of the screw rod 22 is smaller than the inner diameter of the tension spring 32 .

[0051] Specifically, by setting the outer diameter of the screw 22 smaller than the inner diameter of the tension spring 32, there is a gap between the inner diameter of the tension spring 32 and the outer diameter of the screw 22, so that the screw 22 can move freely, avoiding the screw 22 from contacting the tension spring 32 when moving, affecting the feed amount of the screw 22, and further affecting the cutting depth of the cutter 33, slowing down the disassembly efficiency. The screw 22 can realize a more flexible adjustment mechanism, which helps to improve the applicability of the tool.

[0052] like Figure 7 It can be seen that in an optional embodiment of the present invention, the screw 22 is an adjusting screw 22, the feed amount of the screw 22 is S, the pitch of the screw 22 is P, the number of rotations of the screw 22 is N, and: S=N·P.

[0053] Specifically, the feed amount of the screw 22 is S, and the pitch refers to the distance that the screw 22 moves in the axial direction when it rotates one circle. The pitch of the screw 22 is P, and the pitch refers to the distance that the thread advances on the spiral line for one spiral circle. Specifically, the pitch is the vertical distance between two adjacent spiral lines on the thread. The number of rotations of the screw 22 is N, and the relationship between the feed amount and the pitch is: S=N·P. It can be seen that when disassembling different square aluminum shell batteries, according to the model size, only the number of rotations of the screw 22 needs to be adjusted to control the feed amount of the screw 22, so that the cutting depth of the cutter 33 can be controlled, avoiding the cutting height of the cutter 33 being too low, damaging the battery cell, and facilitating the use of the user. By setting the screw 22, the cutting depth of the cutter 33 can be effectively controlled, so that the tool can meet the disassembly needs of square aluminum shell batteries of different models and sizes, which is convenient for users to use and improves the disassembly efficiency of square aluminum shell batteries.

[0054] like Figure 8 It can be seen that in an optional embodiment of the present invention, the cutter 33 is a cutter wheel, and a third opening groove 312 is provided at one end of the fixed seat 31 away from the tension spring 32. The cutter wheel is installed in the third opening groove 312 and can rotate in the third opening groove 312.

[0055] Specifically, by opening a second opening groove 215 on the fixing seat 31, a position suitable for the installation of the cutter wheel is provided, and the cutter wheel can be fixed to avoid loosening or falling off during the cutting process. This design may simplify the replacement or maintenance process of the cutter wheel, making it easier for maintenance personnel to perform equipment maintenance or tool replacement. By rotating the cutter wheel in the third opening groove 312, it may be possible to adjust the cutter wheel to adapt to square aluminum shell batteries of different thicknesses or hardness, thereby optimizing the cutting effect. It should be noted that the cutter wheel is a disc-shaped tool that can form a deep slit on the object to be cut so that the object can be more easily disconnected along the slit and a vertical cutting surface can be reliably formed when the object is disconnected. The main structure of the cutter wheel is a disc-shaped member with a cutting edge along its periphery, which can be installed and fixed through the mounting hole in its center and the irregularly shaped groove. This design helps to ensure the firm fixation of the cutter wheel, improves the stability and safety of the equipment during operation, and may also improve the maintainability and applicability of the equipment.

[0056] In summary, the embodiment of the utility model provides a tool for disassembling square aluminum shell batteries, including a base 10, a limit assembly 20 and a cutter assembly 30. The embodiment of the utility model sets the limit assembly 20. When cutting square aluminum shell batteries of different models and sizes, the screw 22 abuts against the fixing seat 31. The feed amount of the screw 22 on the limit assembly 20 is adjusted by rotation to control the height of the cutter 33 during the cutting process, so that the cutting depth of the cutter 33 can be controlled, thereby preventing the cutting depth of the cutter 33 from affecting the disassembly effect and causing damage to the battery cell. After the cutting is completed, the screw 22 rotates back to the initial position, and the tension spring 32 fixed on the base 21 returns to drive the cutter 33 to reset, which is convenient for users to use, improves operating efficiency, and enhances the convenience and applicability of the tool. The embodiment of the utility model also forms a square mold cavity with adjustable spacing by setting a support assembly, and the abutment member 14 on the support assembly is connected to the side plate of the base 10 by an elastic member 15. When cutting square aluminum shell batteries of different models and sizes, the adjustable design makes the process of fixing the square aluminum shell batteries more flexible and simple, improves the adaptability of the tool, and is suitable for batteries of various specifications. The utility model effectively controls the cutting depth of the cutter 33 by setting a limiter, so that the tool can meet the disassembly requirements of square aluminum shell batteries of different models and sizes, facilitates the different use requirements of users, and improves the disassembly efficiency of square aluminum shell batteries.
