step three: the stator shell assembly connecting tool (050) and the stator shell assembly (030) are firmly positioned and connected, and then positioned and placed on the press-fit supporting plate (230) and locked by bolts;
step four: the right side traversing servo electric cylinder (110) pushes the right side traversing support frame (130) to move leftwards along the right side traversing guide rail (120) until the end part (232-1) of the press-fit flat plate (232) enters the bottom of a notch (233-1) corresponding to the left side support frame (233), then the right side traversing servo electric cylinder (110) and the left side traversing servo electric cylinder (111) act simultaneously to push the right side traversing support frame (130) and the left side traversing support frame (131) to synchronously move leftwards along the right side traversing guide rail (120) and the left side traversing guide rail (121) until a workpiece moves to a press-fit position;
step five: the thimble driving servo cylinder (330) pushes the thimble support frame (320) and the thimble (310) to move downwards along the thimble support frame guide rail (340) until the thimble support frame and the thimble support frame are completely propped against the conical positioning surface of the rotor shaft of the rotor assembly;
step six: the right side pressing servo cylinder (210) and the left side pressing servo cylinder (211) act simultaneously, and the pressing support plate (230) and the stator housing assembly (030) are pushed to move downwards along the right side pressing guide rail (220) and the left side pressing guide rail (221) together with the stator housing assembly connecting tool (050) until the assembly surface of the stator housing assembly (030) is completely attached to the assembly surface of the reducer assembly (020);
step seven: the assembly surface of the stator shell assembly (030) is reliably connected with the reducer assembly (020) by bolts;
step eight: loosening the clamping mechanism, and driving the thimble supporting frame (320) and the thimble (310) to move upwards to the highest point by the thimble driving servo cylinder (330);
step nine: the right pressing servo electric cylinder (210), the left pressing servo electric cylinder (211) and the thimble driving servo electric cylinder (330) act simultaneously, and the pressing supporting plate (230) is pushed to move upwards to a certain position together with the stator shell component connecting tool (050) and the electric driving assembly;
step ten: the right side transverse moving servo electric cylinder acts to push the right side transverse moving support frame (130) together with the press mounting support plate (230), the stator shell component connecting tool (050) and the electric drive assembly to move rightwards to the limit position;
step eleven: loosening a connecting bolt between a stator shell assembly connecting tool (050) and a press-fit supporting plate (230);
step twelve: and (3) discharging the electric drive assembly which is manually hoisted and assembled, and disassembling connecting bolts between a stator shell assembly connecting tool (050) and a stator shell assembly (030), wherein the assembly cycle work of the electric drive assembly is completed.
