That is, the pressure-regulating cylinder has the same function as an elastic member such as a spring, a spring plate and the like, but the elastic member has an elastic fatigue defect, so that the pressure-regulating cylinder is preferably used.
Since the following clamp 191 and the movable cutter 175 act in the same manner, in order to ensure that the first fixing member 193 and the second fixing member 137 already complete clamping and fixing the pole piece before the movable cutter 175 contacts the pole piece, in the present embodiment, when the cutter driving member 171 is in the reset state, that is, when the movable cutter 175 is farthest away from the pole piece in the vertical direction, the first fixing member 193 is closer to the pole piece than the movable cutter 175 in the vertical direction.
In practical application, in the process that the cutter driving member 171 drives the movable cutter 175 to move close to the pole piece through the cam 173, the first fixing member 193 contacts the pole piece in advance, and then the pressure regulating cylinder gradually compresses until the movable cutter 175 contacts the pole piece and cuts off the pole piece. When the pole piece is cut off, the cutter driving member 171 drives the movable cutter 175 to move in a resetting manner, and when the movable cutter 175 is out of contact with the pole piece, the first fixing member 193 and the second fixing member 137 still clamp the pole piece of the cut-off part. In the process of resetting the movable cutter 175, the piston rod of the pressure regulating cylinder is gradually extended, and when the piston rod is extended to the maximum stroke, the first fixing member 193 is driven to be separated from the pole piece.
In addition, in other embodiments, the following clamp 191 may also adopt a self-driven driving device such as an electric cylinder, an oil cylinder, etc. to realize the active driving of the first fixing member 193. For example, if an electric cylinder is used, the first fixing member 193 is connected to an output shaft of the electric cylinder, the electric cylinder may be directly disposed on the mounting bracket 131, and before the movable cutter 175 contacts the pole piece, the electric cylinder actively drives the first fixing member 193 and the second fixing member 137 to complete clamping and fixing of the pole piece.
