[0031] The working principle of the battery pack cutting device of the present invention is as follows: Step 1: During placement and installation, fix the mounting plate 26 on the base by bolts, support the placement platform 17 by the mounting plate 26 to increase the stability of the placement platform 17, and then move the head of the battery pack close to the limit plate 31 for limit.

[0032] Step 2: When the battery pack is cut to a stable limit position, the battery pack is limited on both sides along the two limit frames 25, so that the battery pack is placed at the specified limit position, and the reduction motor 19 is started through the controller 27 on the mounting plate 26, and the reduction motor 19 drives the transmission screw 20 to rotate, and the transmission screw 20 drives the two threaded sleeves 21 to approach each other under the action of the thread transmission force, and at the same time, the two threaded sleeves 21 move along the inner wall of the slide frame 18, so that the distance between the two threaded sleeves 21 becomes smaller, and at the same time, the threaded sleeve 21 drives the connecting strip 22 to move right, and the connecting strip 22 drives the pressing plate 23 to move right, and the pressing plate 23 moves right along the inner wall of the limit frame 25, and the pressing plate 23 is pressed on the left side of the battery pack, and the other pressing plate 23 can be pressed on the right position of the battery pack.

When the distance value sensed by the second distance sensor 24 is the same as the limit distance set by the controller 27, the reduction motor 19 is turned off by the controller 27, so that the two pressure plates 23 can perform stable limit operations on both sides of the battery pack according to the specified limit distance.

[0033] Step 3: When the saw disc is stable and limited in cutting, the controller 27 is used to start the rotating motor 16, which drives the mounting shaft 4 to rotate, and the mounting shaft 4 rotates inside the socket plate 3.
