Vehicle-mounted power battery cover mounting mechanism

Abstract

The utility model belongs to the technical field of power batteries, and particularly relates to a vehicle-mounted power battery cover mounting mechanism which comprises a bottom plate, a base and a pressing mechanism, the base is fixed on the bottom plate, the pressing mechanism comprises a pressing air cylinder, a first connecting rod, a second connecting rod, a third connecting rod and a connecting rod support, the connecting rod support is fixed on the base, and the first connecting rod and the second connecting rod are fixed on the base. One end of the first connecting rod is connected with a piston rod of the pressing air cylinder, the other end of the first connecting rod is provided with two connecting ends which are connected with one end of the second connecting rod and one end of the third connecting rod respectively, the other end of the second connecting rod is connected with one end of the connecting rod support, and the other end of the third connecting rod is connected with a pressing rod. A pressing head is fixed to the bottom of the pressing rod. According to the device, the upper shell can be pressed through the two sets of pressing mechanisms, so that the whole upper shell is uniformly stressed, then the screw is tightened, reciprocating secondary tightening is not needed, and the working efficiency is greatly improved.
