The invention discloses automatic vibration disc body welding equipment, and relates to the field of vibration discs. The automatic vibration disc body welding equipment comprises a bottom plate, wherein a first lead screw is arranged in the bottom plate, a first sliding block is arranged on the outer side of the first lead screw, a first baffle is connected to the top end of the first sliding block, and a second lead screw is arranged at the position, above the first lead screw, in the bottom plate; and a second sliding block is arranged on the outer side of the second lead screw, a second baffle is connected to the top end of the second sliding block, and smoke suction heads are arranged on one side of the second baffle and one side of the first baffle. Through the arrangement of a supporting rod, clamping jaws, a first gear, a second gear, a first motor, a transverse rotating rod, a longitudinal rotating rod, a mounting frame, an air cylinder, a transverse fixing rod and a longitudinal fixing rod, four sets of workpieces are clamped through the four sets of clamping jaws in different directions instead of being welded one by one during welding, and then four sets of welding gunsare used for welding, so that the welding time consumption is reduced, and the welding efficiency is improved.
