Constitute battery pack main body.Supporting body of the battery pack housing as battery module plays the trouble free service and protection of battery module
Key effect, and its protective action is realized by the cover board with explosion-protection equipment being connect with battery pack housing.
In the prior art, the connection type of battery pack housing and cover board is：Seal groove is opened in the surrounding of battery pack housing, is beaten
Threaded hole beats screw thread via on cover board, sealing ring is then placed in the seal groove of shell surrounding, then cover plate lid in battery pack
On shell, screw is finally screwed at threaded hole.
The connection type of existing battery pack housing and cover board has the following problems：One, seal groove and threaded hole are processed
Fineness requires height, long processing time to lead to low production efficiency；Two, the fixed mode of screw is susceptible to mechanical failure and tight
Gu the loosening at position causes its protection effect bad.
Invention content

It washes, removes oxide film dissolving, then wiped with acetone, remove grease, finally dried up with compressed air, form battery pack housing
Cleaning surface and cover board cleaning surface；
Step 2：The fixation of 2-3 μ m thicks is smeared in battery pack shell body cleaning face and cover board cleaning surface by pre-pressing respectively
Glue, and preliminary pressing is docked on two sides；
Step 3：The workpiece that step 2 obtains is placed on welding tooling by clamping workpiece；
Step 4：Pre- hot melt, the screw of FDS equipment exert a force to the surface of workpiece, and high-speed rotation is to welding position
Processing preheating；
Step 5：Welding, the screw of FDS equipment sequentially pass through cover board and shell under certain pressure and rotating speed；
Step 6：Fastening, FDS equipment tighten screw by certain screwing force, the fastening of 1 position are completed, under continuing
The fastening of one position.
It further says, the fixing glue in the step 2 includes following components：Methacrylic acid, butadiene-styrene latex, end ammonia
Base fluid body nitrile rubber, polyvinyl resin, antifoaming agent and antiager.
It further says, the fastening position in the step 6 is distributed in the end face one week of cover board.
It further says, the rotating speed of screw is 8000r/min in the step 4.
It further says, the down force pressure of screw is 280-320N in the step 5, and the rotating speed of screw is 350r/
min。
It further says, the screwing force in the step 6 is 15-25N.
It further says, the screw is mild steel screw, brass screws nail or ALUMINUM SCREWS nail.
It further says, the screw carries out carburizing and quenching processing before processing.
The beneficial effects of the invention are as follows：The present invention replaces original fixed mode of screw, using FDS to battery pack housing
Carry out riveting fixation with cover board, can improve the compactness that battery pack housing is connect with cover board, the riveting process it is efficient, at
The defects of stability of product is high, flawless, undercut, stomata, recess.
