This utility model discloses a battery aluminum shell edge trimming device, belonging to the field of battery aluminum shell processing. It mainly includes a cutting assembly, which comprises a movable plate connected by four sets of support pillars. Cutting sections are installed on the four sides of the movable plate, each including a side connecting block mounted on the side of the movable plate. Each side connecting block has a U-shaped groove and a second U-shaped groove on its connecting side to the movable plate. A fixed seat is installed on the side connecting block, and a second cylinder is installed on the fixed seat. The output end of the second cylinder is connected to a connecting plate, and a third cylinder is installed on the connecting plate. The telescopic end of the third cylinder is connected to the fixed section. A U-shaped rod is installed on the fixed section, and a saw blade movably passes through the two right-angled ends of the U-shaped rod. The saw blade has inserts at both ends that form sliding pairs with the right-angled ends of the U-shaped rod. A pushing part is installed on the connecting plate. This battery aluminum shell edge trimming device, by connecting the movable plate and the cutting sections through support pillars, replaces traditional rotary cutting, controls the saw blade to achieve independent cutting, disperses stress, and reduces burrs.
