[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] Reference Figures 2 to 4 , the utility model provides an embodiment: a kind of multi-station pneumatic clamp of battery shell, including base 1, the rear end of base 1 is fixedly connected with multiple drive assemblies, the drive end of drive assembly is fixedly connected with moving plate 3, drive assembly includes rotary cylinder 2, the front end of rotary cylinder 2 is fixedly connected in the rear end of base 1, the drive end of rotary cylinder 2 is fixedly connected in the rear end of moving plate 3, when rotary cylinder 2 starts, it can drive moving plate 3 movement, so that moving plate 3 starts to move and drives subsequent structure to adjust, by this mode, drive assembly can efficiently realize the clamping and positioning of battery shell.

[0027] The inner wall of moving plate 3 is fixedly connected with spring one 4 on both sides, the other end of spring one 4 is fixedly connected with limiting block 5, the end, away from spring one 4, of limiting block 5 is fixedly connected with connecting column 6, the other end of connecting column 6 is fixedly connected with positioning plate 7, spring one 4 adjusts the position of limiting block 5 by elastic force, accurately limits battery shell 9 when operating equipment, the contact of limiting block 5 and battery shell 9 can effectively prevent unnecessary displacement of battery shell 9 in operating process, to improve work stability.

[0028] Reference Figure 1 And Figure 3 , the front end of base 1 is fixedly connected with multiple clamping blocks 8, battery shell 9 is installed in the inner wall of every two clamping blocks 8, battery shell 9 is always kept in a fixed position under the clamping of the inner wall of clamping block 8, this structure design ensures the accuracy of clamp in operating process, and reduces any possible error, the design of clamping block 8, especially the installation mode of inner wall, makes that clamp can effectively adapt to battery shell 9 of different sizes.

[0029] The outer sliding connection of the limiting block 5 is connected to the inner wall of the moving plate 3, and one side of the positioning plate 7 is in contact with the outside of the battery shell 9. When the device is in operation, the movement of the moving plate 3 will drive the positioning plate 7 to contact the battery shell 9. In this way, the positioning plate 7 ensures that the battery shell 9 is accurately positioned and prevents it from shifting. The precise control of the positioning plate 7 is the core of the efficient operation of the device, avoiding the positioning error that may occur in the battery shell 9.

[0030] Reference Figure 5 The front end of the base 1 is fixedly connected with a protection assembly, which includes a plurality of telescopic rods 10. The rear ends of the telescopic rods 10 are fixedly connected to the front end of the base 1. The outside of the telescopic rod 10 is provided with a spring 11. The front ends of the two telescopic rods 10 are fixedly connected with a buffer plate 12. The front end of the buffer plate 12 is in contact with the rear end of the battery shell 9. The function of the protection assembly is to prevent the battery shell 9 from being impacted by excessive pressure or external force, ensuring that no damage occurs during operation. The function of the spring 11 is to provide a buffering force through deformation, ensuring that the buffer plate 12 can be in contact with the battery shell 9 with appropriate force, thereby effectively protecting the battery shell 9 from damage.

[0031] One end of the spring 11 is fixedly connected to one side of the base 1, and the other end of the spring 11 is fixedly connected to one side of the buffer plate 12.

[0032] Working principle: when the device needs to be used, the battery shell 9 is placed in the inner wall of the clamping block 8. At this time, the rotating cylinder 2 is started, which can drive the moving plate 3 to move, so that the moving plate 3 moves and rotates. At this time, the moving plate 3 will drive the positioning plate 7 to move, and the positioning plate 7 will push the connecting column 6 to make the limiting block 5 extrude the spring 4. At this time, the spring 4 will deform to generate elastic potential energy, which will make the positioning plate 7 resist the battery shell 9 and provide elastic force at the same time, avoiding damage caused by direct clamping of the battery shell 9 by the positioning plate 7, thereby providing protection. In this process, the battery shell 9 will push the buffer plate 12, which will push the telescopic rod 10 to make the spring 11 deform, thereby providing protection for the battery shell 9 through the buffering force on both sides, avoiding damage caused by direct clamping to the battery shell 9.
