Lifting type automobile machining plate laser welding mechanism

The utility model discloses a lifting type automobile machining plate laser welding mechanism. Machine base comprises a machine base body, a transverse sliding groove is formed in the middle of the top face of the machine base body in the transverse direction. And the transverse sliding groove is a dovetail-shaped groove, a storage assembly is slidably connected into the transverse sliding groove,a supporting plate is fixed to one side of the top face of the machine base body, a top plate is fixed to the top end of the supporting plate in the horizontal direction, a longitudinal sliding groove is formed in the top plate in the longitudinal direction, and the longitudinal sliding groove is a dovetail-shaped groove. The welding device has the advantages that the air cylinder works to drivethe welding device body at the bottom end of the plunger rod to ascend and descend to adjust the working height of the welding device body so as to adapt to automobile machining plates with differentthicknesses placed on the w
