Auxiliary tool for welding process of silencer core assembly

The utility model discloses an auxiliary tool for a silencer core assembly welding process. The auxiliary tool comprises an air inlet pipe positioning piece, an exhaust pipe positioning piece and a partition plate positioning piece. During welding, the distance between the air inlet pipe positioning piece and the exhaust pipe positioning piece can be determined according to the axial distance between the air inlet pipe and the exhaust pipe in the machined core assembly; the two are fixed on the mounting base; similarly, according to the height positions among the clapboards in the processed core assembly, the clapboards are separated; each corresponding partition plate positioning piece is positioned at the corresponding height; in this way, the distance between the air inlet pipe and theair outlet pipe, the distance between the adjacent partition plates, the distance between the partition plates and the air inlet pipe and the distance between the partition plates and the air outlet pipe can be accurately pos
