Locating spot welding equipment of fan impeller blade

The invention provides a locating spot welding equipment of a fan impeller blade, which is applicable to the technical field of fan impeller production. The locating spot welding equipment of the fan impeller blade is provided with a supporting platform; one end of the supporting platform is provided with a rotary working platform with a central hole by a locating shaft; the locating shaft penetrates through the central hole of the rotary working platform; a wheel plate to be spot-welded is fixedly arranged on the rotary working platform; the other end of the supporting platform is provided with a working platform guide rail, on which a dragging plate is arranged in a sliding way; a supporting column is arranged on the dragging plate; a blade locating supporting frame is sleeved on the supporting column in a sliding way; and the blade locating supporting frame is matched with the rotary working platform so as to locate and spot-weld the blade on the wheel plate; therefore, spot-welding of the blade is carried out in a semi-automatic way, the working efficiency is increased and an accumulated error of an impeller group is reduced, so that the integral property of a fan is guaranteed.
