Fan blade welding device

The invention discloses a fan blade welding device. The fan blade welding device comprises a rack, a rotating assembly, a fixing assembly and a moving assembly. The rotating assembly comprises a sleeving end and a first driving part, and the axis of the sleeving end is obliquely arranged. The fixing assembly comprises a moving seat, a fixing groove, a moving part and a lifting machine, a first sliding rail is arranged between the moving seat and the rack, and a first reciprocating part is arranged on the rack; the moving assembly comprises a second sliding rail and a sliding block arranged on the second sliding rail, a storage groove is formed in the lower portion of the second sliding rail, and a negative pressure suction cup is arranged on the sliding block. To-be-welded fan blades are moved through the negative pressure suction cup, and it is guaranteed that the to-be-welded fan blades cannot be scratched due to friction in the moving process; the stacked to-be-welded fan blades can be directly placed into
