Completely automatic device for stretching and shifting lithium battery shell

The invention relates to a device for stretching and shifting a lithium battery shell, in particular to a completely automatic device for stretching and shifting lithium battery shell. Two identical pneumatic shifting mechanisms are arranged at two sides of the work top of a stretching machine so as to drive a battery shell clamping block, thus realizing the movement of the battery shell to the left and right; two identical mechanical fork-levers are arranged at two sides of the upper mould of a stretching die and are matched with a pneumatic compensation mechanism so as to realize the location clamping and loosening of the battery shell; and an upper mechanism and a lower mechanism are matched with each other, thus achieving the directional intermittent movement of the battery shell. Thedevice has the beneficial effects of small volume, easy installation, consuming little stretching force of the stretching machine, reliable clamping and shifting operation, simple debugging, automatically identifying the prof
