The utility model discloses a pre-tightening device for a square aluminum shell battery cell module, which is used for solving the problems of low production efficiency due to manual sequencing and pre-tightening in the assembling process of the square aluminum shell battery cell module in the prior art and relatively complicated and poor applicability of the existing pre-tightening device. The device comprises a bottom plate, side plates and a pressing assembly are fixedly arranged at the upper end of the bottom plate, the side plates are arranged in parallel in the long edge direction of the bottom plate, the longitudinal sections of the side plates are perpendicular to the transverse section of the bottom plate, and the pressing assembly is divided into a left part and a right part which are marked as a fixing part and a pressing part respectively; the square aluminum shell battery cell module is arranged between the fixing part and the pressing part in the long edge direction of the bottom plate, the fixi
