[0021] A processing method for a square lithium battery shell fixing processing device comprises the following steps: Step 1: The motor 201 drives the reciprocating screw 202, and the cross-shaped spiral groove on the reciprocating screw 202 drives the concave plate 204 to move; Step 2: The concave plate 204 moves to drive the clamping plate 205 to move, and the square lithium battery shell is fixed by the clamping plate 205; Step 3: The L-shaped block 211 is moved by the concave plate 204, and the L-shaped block 211 moves to contact the hinge plate 1 207. When the device is reset, the hinge plate 1 207 is limited by the limit plate 208, so that the L-shaped block 211 drives the hinge plate 1 207 to rotate; Step 4: The hinged plate 207 rotates to drive the T-shaped column 209 to rotate, the T-shaped column 209 rotates to drive the material receiving block 210 to rotate, and the material receiving block 210 rotates to drive the lithium battery shell to rotate, so that the drill bit can drill holes in the lithium battery shell.

[0022] Working principle: The guide plate 401 moves upward through the movement of the telescopic plate 303, and the guide plate 401 moves downward to drive the traction plate 402, and the traction plate 402 moves downward to drive the return plate 403 to move downward, and the spring 404 is reset, and the traction plate 402 moves downward to fix the top of the square lithium battery shell, so that the drill bit is more stable when drilling, and the position accuracy is guaranteed. When the traction plate 402 moves downward to fix the top of the square lithium battery shell, it is like providing a precise coordinate for the drilling operation of the drill bit, because the shell is firmly fixed in a stable position. The drill bit can drill accurately according to the preset position during the drilling process. For the situation where it is necessary to drill holes at specific positions of the shell to install components such as electrodes, this fixing method can ensure that the position error of the hole is controlled within a very small range, thereby ensuring the accuracy of subsequent component installation. The movement of the return plate 403 drives the movement of the triangular plate 408, and the triangular plate 408 moves and contacts with the guide plate 407, so that the guide plate 407 moves and is reset by the spring 406, so that the cutting oil in the filter barrel 405 falls evenly when the drill bit is drilling, making drilling more convenient and quick.
