Detailed Description
In the description of the present invention, unless otherwise specified, the terms "upper", "lower", "left", "right", "front", "rear", and the like indicate orientations or positional relationships only for the purpose of describing the present invention and simplifying the description, but do not indicate or imply that the device or structure referred to must have a particular orientation and therefore should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
As shown in FIG. 1, a cylinder battery homonymy welded pressure head frock include connecting block 1, first pressure head 3 and second pressure head 4, wherein, the connecting block is used for being connected with laser welding equipment, first pressure head is used for compaction pole piece and cylinder casing positive pole, the second pressure head is used for compaction pole piece and cylinder casing negative pole, so can solve cylinder battery 9 and appear the problem when homonymy face of weld has the difference in height on a pressure head frock.
In the above, the connecting block, the first pressing head and the second pressing head are made of an integrated piece made of luohao copper or red copper, the first pressing head is preferably rectangular, and the second pressing head is preferably circular.
The specific scheme for solving the problems is as follows:
as shown in fig. 1, firstly, a conical groove 2 with a large upper inner diameter and a small lower inner diameter is arranged on the connecting block; secondly, as shown in fig. 2, the first pressure head 3 and the second pressure head 4 are both fixedly connected to the lower end face of the connecting block and are provided with through holes 5 which are arranged along the vertical direction and communicated to the conical groove, so that when the connecting block is installed on laser welding equipment, laser passes through the conical groove and the two through holes to be respectively welded; finally, as shown in fig. 2 and 3, because of the height difference of the welding surfaces on the same side surface, the height difference exists between the pressing surface of the first pressing head and the pressing surface of the second pressing head in the vertical direction, so that the welding surfaces with the height difference on one pressing head tool can be attached.
