[0025] Reference Figure 1-Figure 5A new energy vehicle battery pack shell manufacturing device includes a processing box 1. The processing box 1 is a closed structure for accommodating the main components of the entire manufacturing device and protecting the equipment from the influence of the external environment. The processing box 1 is provided with a protective door 2, which is fixed to the processing box 1 by a precision hinge so that it can be opened and closed smoothly. The outer wall of the protective door 2 is fixedly connected with a handle 3. The handle 3 is convenient for the operator to open and close the protective door to ensure the safety and convenience of the operation. The outer wall of the processing box 1 is fixedly connected with a fixed box 4. The fixed box 4 is a small box, which is usually formed by stamping a metal sheet and welded to the outer wall of the processing box 1. A motor 5 is fixedly connected to the top of the fixed box 4. The motor 5 is a power source that drives the subsequent motion mechanism. The output shaft is vertically downward. The output end of the motor 5 is fixedly connected with a rotating rod 6. The rotating rod 6 is made of high-precision metal material and has sufficient rigidity and torsion resistance to ensure the precision of the moving block 7 when moving. Accuracy and stability, the rotating rod 6 is connected to the moving block 7, the inner wall of the processing box 1 is fixedly connected to the cross bar 11, and the outer wall of the cross bar 11 is slidably connected to the sleeve 10, the sleeve 10 can slide freely on the cross bar 11, and rollers or guide rails are arranged inside the sleeve 10 to reduce friction and ensure smooth movement. The sleeve 10 and the moving block 7 are connected by a driving mechanism, and the bottom of the sleeve 10 is connected to a cutting machine 12. The cutting machine 12 can use high-precision electric control or CNC cutting equipment, which is fixed to the bottom of the sleeve 10 by fasteners. You can choose a suitable cutting tool or laser head according to your needs. This is the prior art and will not be described here. A support plate 13 is fixedly connected to the bottom of the processing box 1, and an anti-slip material can be added to the surface of the support plate 13 to improve the stability of the battery pack shell. Two symmetrically arranged clamping mechanisms are fixedly connected to the bottom of the processing box 1. The clamping mechanism is used to fix battery pack shells of different sizes and shapes to ensure stability during the cutting process.

[0026] The driving mechanism includes a fixed block 9 fixedly connected to the top of the sleeve plate 10. The outer walls of the fixed block 9 and the movable block 7 are fixedly connected with a rotating shaft. The two rotating shafts are connected by a linkage rod 8. The setting of the linkage rod 8 enables the movement between the fixed block 9 and the movable block 7 to be coordinated, thereby achieving precise positioning and operation. Rotating openings are provided at both ends of the linkage rod 8, and the two rotating openings are respectively rotatably socketed with the outer walls of the rotating shaft. Moving openings for the movement of the linkage rod 8 are provided on the side walls of the processing box 1 and the fixed box 4. This structure enables the linkage rod 8 to move freely in a specific area without interfering with other components, thereby ensuring the stability and reliability of the entire device.

[0027] An external thread is provided on the outer wall of the rotating rod 6, a threaded opening is provided on the moving block 7, and an internal thread matching the external thread is provided on the inner wall of the threaded opening. The threaded opening is threadedly sleeved with the outer wall of the rotating rod 6. In this way, when the rotating rod 6 rotates, the moving block 7 can move axially along the rotating rod 6. The connection method between the rotating rod 6 and the moving block 7 is simple and reliable, which is suitable for high-precision positioning and adjustment requirements. The device can be easily installed and maintained, reducing the difficulty of operation.

[0028] The clamping mechanism includes two symmetrically arranged side plates 14, the bottom of the side plates 14 is fixedly connected to the bottom of the processing box 1, and the same positioning rod 15 is fixedly connected to the opposite side of the two side plates 14. The outer wall of the positioning rod 15 is rotatably connected to a rotating plate 16, and the two ends of the rotating plate 16 are respectively connected to a pressure head 17 and a protrusion 19, and the pressure head 17 is arranged in a cylindrical shape. The selection of the cylindrical shape can make the pressure head 17 evenly distributed during the pressure application process to avoid deformation or damage of the shell caused by excessive local pressure. The protrusion 19 is connected to a driving mechanism, and the driving mechanism includes a cylinder 18 fixedly connected to the bottom of the processing box 1, and a fixing plate 20 is fixedly connected to the top of the cylinder 18. Corresponding connecting ports are provided on the protrusion 19 and the fixing plate 20. The connecting ports on the protrusion 19 and the fixing plate should be designed to corresponding shapes and sizes to ensure that the connecting shaft can be smoothly inserted and realize rotational connection. The two connecting ports are rotationally connected through the connecting shaft. Through a simple and effective mechanical transmission design, the effective fixation of the battery pack shell of the new energy vehicle is achieved, and the stability of the subsequent processing process is ensured.

[0029] The specific working principle of the present invention is as follows:

[0030] In actual operation, when the device is used, first, the operator opens the protective door 2 through the handle 3 on the protective door 2, and places the battery pack shell to be processed on the pallet 13 inside the processing box 1. Then, the protective door 2 is closed and the motor 5 in the fixed box 4 is started. The motor 5 drives the rotating rod 6 to rotate, and then the moving block 7 connected to the rotating rod 6 moves up and down along its path. At the same time, the sleeve plate 10 is connected to the moving block 7 through a driving mechanism, so as the moving block 7 moves, the sleeve plate 10 will also slide horizontally on the outer wall along the cross bar 11, and the cutting machine 12 located at the bottom of the sleeve plate 10 will move accordingly to perform precision cutting at the specified position of the battery pack shell.

[0031] To ensure the stability and accuracy of the processing, clamping mechanisms are provided on both sides of the bottom of the processing box 1. The cylinder 18 is started, and the cylinder 18 drives the rotating plate 16 to rotate, so that the pressing head 17 can move up and down conveniently and automatically clamp the battery pack shell during the processing to prevent it from displacement.

[0032] The whole set of actions is driven by the motor 5, and through the exquisite coordination between the various components, efficient and stable battery pack shell manufacturing is achieved. During the entire manufacturing process, the protective door 2 also plays a role in safety protection, preventing debris from splashing during the processing, ensuring the safety of the operator and facilitating the collection of debris.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
