Detailed Description

As shown in fig. 1-2, a power battery welding tool comprises a welding platform 1, a positioning groove 101, a clamping mechanism and a pressing mechanism are arranged on the welding platform 1, the positioning groove 101 is matched with an outer shell of a power battery, the clamping mechanism comprises clamping cylinders 2 arranged on two sides of the positioning groove 101, clamping blocks 3 are arranged on telescopic rods of the clamping cylinders 2, the pressing mechanism comprises a support 4 and a pressing cylinder 5 arranged on the support 4, a pressing block 6 is arranged on a telescopic rod of the pressing cylinder 5, the pressing block 6 is arranged right above the positioning groove 101, a material returning cylinder 7 is arranged on one side of the support 4, a material returning plate 8 is arranged on a telescopic rod of the material returning cylinder 7, a support frame 9 is arranged below the welding platform 1, and a lifting mechanism 10 is arranged on, in this embodiment, the lifting mechanism 10 is a lifting cylinder, a lifting plate 11 is disposed on the top of the lifting mechanism 10, and a through hole 102 adapted to the lifting plate 11 is disposed at the bottom of the positioning slot 101.

When the welding device is used specifically, a battery to be welded is placed in the positioning groove 101, position determination is achieved, the clamping cylinder 2 is started to drive the clamping block 3 to move oppositely, the battery to be welded is fixed, after the battery to be welded is fixed, the battery cover plate is placed at the top of the battery to be welded, the pressing cylinder 5 is started, the pressing block 6 is driven to press and fix the cover plate, then welding equipment welds the battery, after welding is completed, the clamping cylinder 2 and the pressing cylinder 5 retract, limiting on the power battery is removed, the lifting mechanism 10 is started, the lifting plate 11 penetrates through the through hole 102 to ascend, the battery is lifted, the lifting plate 11 stops ascending after moving to be flush with the welding platform 1, the material returning cylinder 7 is started to drive the material returning plate 8 to move, the battery is returned, the battery is made to leave a welding area, and welding operation of the next.
