Seat 11 is the mounting platform to match with shell 50, and shell 50 and the battery core 40 in shell 50 are located at by the first limit assembly
In the mounting platform limited with the second limit assembly, the accuracy of 40 position of battery core, avoids battery core 40 when ensure that welding
It shakes.
Specifically, the first limit assembly and the second limit assembly are separately at least one set of, as shown in Figure 1, first
Limit assembly is spaced two groups, and every group of first limit assembly includes being separately positioned on shell 50 along first direction both ends
The first limited block 12；Second limit assembly is one group, and the second limit assembly includes being separately positioned on shell 50 in a second direction
Second limited block 13 at both ends.
It should be noted that in the embodiment shown in the utility model, two first in every group of first limit assembly
Two the second limited blocks 13 in limited block 12 and the second limit assembly, which can be, immovably to be installed on the pedestal 11,
That is the battery that a welding tooling is only used for a kind of model.In the unshowned embodiment of the utility model, every group first limit
Two the first limited blocks 12 in hyte part or/and two the second limited blocks 13 in the second limit assembly can be movable
Ground is installed on the pedestal 11, i.e. distance is adjustable or/and two between two the first limited blocks 12 in every group of first limit assembly
The distance between second limited block 13 is adjustable, and a welding tooling can be used for various types of batteries.For example, two second limits
One in block 13 can be relative to another movement, and specifically, welding tooling further includes the elastic components such as spring, one end of elastic component
On the pedestal 11, the other end is installed therein on second limited block 13 for installation, when not applying external force state, two second limits
Position block 13 can in a second direction to battery limiting, when needing placing battery, in a second direction to elastic component apply external force, two
The distance between a second limited block 13 increases, and is put into battery, then removes external force, under the action of elastic restoring force, two
Second limited block 13 restores again to the limit state to battery.At this point, different rulers can be applicable between two the second limited blocks 13
Very little battery.In order to better adapt to the installation of multi-model number, positioning seat 20 is also required to match with mounting base 10, such as:
The size of positioning seat 20 and the cover plate assembly size of respective battery match, the distance between positioning seat 20 and mounting base 10 also with
The distance between the tab of respective battery and connection sheet match.
