As shown in fig. 1, the present embodiment provides an adjustable tooling, which includes a fixing structure 1 and an adjusting baffle 2. The two fixing structures 1 are oppositely arranged along a first direction and are surrounded to form an accommodating cavity 101 capable of accommodating the battery cell 4, and the distance between the two fixing structures 1 is adjustable; the adjusting baffle plates 2 are transversely connected to the two fixing structures 1 along the first direction, the positions of the adjusting baffle plates 2 in the second direction are adjustable, the first direction is perpendicular to the second direction, the first direction is ab direction shown in fig. 1, and the second direction is cd direction shown in fig. 1.

Specifically, the adjusting baffle 2 is located on the fixing structure 1, and can be optionally arranged at any position of the surface of the fixing structure 1 contacting with the adjusting baffle 2, the adjustment of the accommodating cavity 101 formed by enclosing the two fixing structures 1 in the first direction is realized by changing the position of the relative arrangement of the two fixing structures 1, and further, the size of the accommodating cavity 101 in the second direction is realized by adjusting the position of the adjusting baffle 2 relative to the fixing structure 1.

Further, adjustable frock still includes fastener 3, and fastener 3 connects in two fixed knot construct 1, and can adjust the distance of two fixed knot constructs 1 in the first direction. Specifically, two after fixed knot constructs 1 sets up relatively, adopt fastener 3 to fix, according to actual production demand, can utilize fastener 3 to adjust two fixed knot to construct 1's relative position in the first direction.

Specifically, the fastener 3 is provided in two, and each fastener 3 includes a bolt 31 and a nut 32. In the second direction, two sides of the two fixing structures 1 are respectively provided with a fixing lug 13, and the bolt 31 can simultaneously penetrate through the two fixing lugs 13 on the same side, so as to connect the two fixing structures 1 together, further, the relative distance between the two fixing structures 1 is also adjusted by the bolt 31, that is, the width change interval of the accommodating cavity 101 in the first direction is the length change interval of the bolt 31 in the middle of the two fixing structures 1. In the present embodiment, as shown in fig. 2 and 3, because different battery cells 4 are disposed, the relative positions of the two fixing structures 1 in the first direction are also different, i.e., the width of the accommodating cavity 101 is adjusted accordingly by the fastening member 3.

As shown in fig. 1, magnets 11 are disposed in the two fixing structures 1 and the adjusting baffle 2, and the position of the adjusting baffle 2 relative to the fixing structures 1 is adjustable in the second direction, in this embodiment, the adjusting baffle 2 can be disposed at any position of the fixing structures 1 on the surface where the fixing structures 1 and the adjusting baffle 2 contact, which is achieved by disposing the magnets 11 inside the two fixing structures 1 and the adjusting baffle 2 for adsorption fixation.

Of course, in another embodiment, the adjustable fixture may further include a ferromagnetic component and a magnet 11, one of the ferromagnetic component and the magnet is disposed on the fixed structure 1, and the other is disposed on the adjusting baffle 2, and the ferromagnetic component and the magnet 11 cooperate to fix the adjusting baffle 2 to the fixed structure 1. Specifically, one of the optional fixing structure 1 or the adjusting baffle 2 is provided with a magnet 11, and the other is provided with a metal block which is attracted to the magnet 11. In another embodiment, the fixing and adjusting of the position between the fixing structure 1 and the adjusting baffle 2 can also be performed by providing a series of grooves on the surface of the fixing structure 1 that is matched with the adjusting baffle 2, so as to perform clamping and fixing. Or a series of fixing holes are formed in the surfaces of the fixing structure 1 and the adjusting baffle 2, through holes matched with the fixing structure are formed in the adjusting baffle 2, and the fixing structure 1 and the adjusting baffle 2 are fixed through the fixing part in a matched mode, so that the fixing structure 1 and the adjusting baffle 2 are matched firmly.
