Sealing and welding robot for main silencer barrel body of silencer

The utility model belongs to the field of sealing and welding of silencer main silencer cylinder bodies, and particularly relates to a silencer main silencer cylinder body sealing and welding robot which comprises a bottom frame panel, the outer end of the bottom frame panel is fixedly connected with a sealing plate, the upper portion of the bottom frame panel is connected with a silencer main silencer cylinder body, and the silencer main silencer cylinder body is connected with the sealing plate. The left side of the upper end of the bottom frame panel is fixedly connected with a driving box base, so that when a welding seam of the silencer main silencer barrel is welded, after the silencer main silencer barrel is fixed, the air cylinder is pushed to drive the push rod to move towards the two ends of the silencer main silencer barrel, then the push rod ejects out the sealing cover follow-up jig, and then the sealing cover follow-up jig is pushed out. The sealing cover follow-up jig is used for buckling the s
