Square head bolt, ball screw nut etc., and the end of threaded portion be pyramidal structure, convenient for bolt installation when centering screwhole position,
The bolt can directly selection standard part restructured.
Further, the mould group is made of multiple battery cores, and four fixed feets are arranged in mould group, setting half in each fixed feet
Waist hole, the center of two waist hole semicircles being centrally formed is away from the center of screw hole formation in less than two fixed beams away from waist hole width
Greater than the nominal diameter of bolt, when installation, mould group can be moved along mould group waist hole length direction and fixed beam length direction, adjustment
To after suitable position, fixation is tightened by bolt.
Further, the nut, plain washer, spring washer can directly selection standard part, plain washer connect for increasing
Contacting surface product, spring washer are used for bolt connection anti-loose.
The utility model has the beneficial effects that:
1, mould group installs simple and fast, high production efficiency；
2, structure is simple, and installation is reliable and stable, ensure that the safe operation and service life of battery；
3, processing part can suitably reduce the accuracy of manufacture, improve production efficiency, reduce cost.
