Abstract

The invention discloses a welding fixture for welding a blade on a rotor. The welding fixture for welding the blade on the rotor comprises a first copper electrode and a second copper electrode. The first electrode comprises a fixing seat, a rotary plate and a rotor bearing seat, wherein the fixing seat, the rotary plate and the rotor bearing seat are sequentially arranged; the rotary plate is sleeved on the rotor bearing seat and is fixedly connected with the rotor bearing seat; a protruding block at the front end of the rotor bearing seat is inserted in the fixing seat; the rotor bearing seat rotates around the fixing seat; the diameter of a bearing end at the rear end of the rotor bearing seat is matched with the inner diameter of the rotor; a positioning groove for positioning the rotor is formed in the outer circle of the bearing end; an accommodating groove for bearing the blade is arranged on the second electrode; a compression sheet for pressing the blade in the accommodating groove is locked on the second electrode through a bolt. The welding fixture for welding the blade on the rotor achieves the purposes that the blade and the rotor are accurately positioned between the electrodes, the welding precision of the blade and the rotor is guarantees, and welding quality and production efficiency are improved.

Description

technical field [0001] The invention relates to the motor manufacturing industry, in particular to a welding tool for welding blades on a rotor. Background technique [0002] Resistance welding includes spot welding, seam welding, butt welding and projection welding, among which spot welding is the most widely used. Spot welding is a resistance welding method in which the weldment is assembled into a lap joint and pressed between two columnar electrodes, and the base metal is melted by resistance heat to form a solder joint. Compared with arc welding, resistance spot welding has the advantages of high thermal efficiency and dense weld seam, and is suitable for welding thin plate parts. [0003] In today's impeller manufacturing process, welded impellers are dominant, and the welding quality between the blade and the rotor directly affects whether the blade rotor can work normally. Resistance spot welding needs to press the welding workpiece between two electrodes, and the ...
