Detailed description of the invention
With the following Examples the utility model is further described.
A kind of battery slot rolling instrument of the present embodiment, as depicted in figs. 1 and 2, comprise cylindrical slot rolling 42 body 1 and the slot rolling head 2 being located at cylindrical slot rolling 42 body 1 one end, described slot rolling head 2 comprises three circle bodies, be respectively the A circle body 21 stacked gradually, B circle body 22 and C circle body 23, A circle body 21 directly maximum, the diameter of C circle body 23 is minimum, the diameter of B circle body 22 is between A circle body 21 and B circle body 22, A circle body 21 is near cylindrical slot rolling 42 body 1, described slot rolling head 2 is arranged with annular sleeve 3, the space for holding battery case is had between described annular sleeve 3 and slot rolling head 2.
The battery case of three applicable two kinds of different inner diameters of circle body carries out slot rolling 42, such as, when the internal diameter of battery case is applicable to being enclosed within C circle body 23, annular sleeve 3 is just enclosed within C circle body 23, B circle body 22 is for supporting the opening 41 of annular sleeve 3 and battery case, before slot rolling 42, the opening 41 of battery case is inserted between C circle body 23 and annular sleeve 3, utilize the opening 41 of annular sleeve 3 and C circle body 23 self-contained battery shell, the opening 41 of battery case can be made can not to be out of shape because of stressed during slot rolling 42, also can to control the precision of slot rolling 42 well.
In like manner, when the internal diameter of battery case is applicable to being enclosed within B circle body 22, annular sleeve 3 is just enclosed within B circle body 22, A circle body 21 for supporting the opening 41 of annular sleeve 3 and battery case, before slot rolling 42, is inserted between B circle body 22 and annular sleeve 3 by the opening 41 of battery case.
Concrete, described C circle body 23 is provided with protuberance 24, and described protuberance 24 can insert battery case, because battery core need be placed in battery case inside, pad can be utilized to be enclosed within two lugs of battery core, for fixing battery core, but during due to slot rolling 42, battery rotates with slot rolling head 2, and pad may be shifted, and makes battery core also produce displacement, by being provided with protuberance 24 on C circle body 23, utilize protuberance 24 to withstand pad, make in the process of slot rolling 42, pad is indeformable not to be shifted.
Concrete, described protuberance 24 is set to the protuberance 24 of annular, because pad is circular, therefore, utilizes both can passing for the lug of battery core of annular, can withstand pad again.
