Embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1：
As shown in Figure 1 and Figure 2, a kind of electric core of lithium ion power battery is accurately positioned the device master of bilateral synchronous horizontal punching
To include base fixing plate 1, the left and right above base fixing plate and promote assembly, cover half 6, upper mould assembly.
Base fixing plate 1 is provided through the left and right and promotes assembly slide 17, cover half 6, the positioning hole of spring bottom plate 5, leads to
Crossing bolt promotes assembly, cover half 6 to be combined together with base fixing plate 1 left and right, to ensure in left and right red needle 14 and cover half 6
Holding is put accurate, so as to improve drilling precision.Base fixing plate 1 be provided with the position identical chip-removal hole of cover half 6, chip is direct
Chip removal bucket is discharged into, it is to avoid drilling operation is influenceed because of talus accumulation, so as to reduce the possibility that chip enters battery.
Cross through hole of the cover half 6 provided with control hole size and distance, cooperates with red needle specification position, constitutes bicker
Structure, the cover half 6 is hollow, and bottom is provided with chip-removal hole, and each punching chip is expelled directly out.
Left and right promote assembly symmetrically, structure is identical, be respectively equipped with spring bottom plate 5, spring pull bar 3, die sinking spring 4,
Spring base 2, dynamic model pressing plate 19, slide 17, dynamic wedge 16, red needle 14, holddown spring 13, red needle fixed plate 15, pressing plate 18, pressing plate
Return plate 12.Upper mould assembly, which is located at cover half 6, left and right, to be promoted above assembly, and the upper mould assembly is provided with upper wedge 7, cover half pressing plate
