Motor stator core welding device and manufacturing method

Abstract

The present invention relates to the technical field of welding devices, and in particular to a motor stator core welding device and a manufacturing method thereof, wherein the motor stator core welding device comprises a bracket, a limiting straight rod, a guide rod and a driving member, a plurality of silicon steel sheets are placed on the bracket, and under the action of a first clamp and a second clamp, the plurality of silicon steel sheets will not move in the axial and radial directions. In this state, the limiting straight rod is simultaneously inserted into the welding grooves of the plurality of silicon steel sheets, and a first driving source in the driving member twists the plurality of silicon steel sheets, and under the action of a second driving member in the driving member, the limiting straight rod and the guide rod move alternately in the welding groove, and when the guide rod enters the welding groove, two adjacent silicon steel sheets rotate relative to each other, so that the welding grooves of the plurality of silicon steel sheets are spirally shaped, and under the action of the guide rod, the spiral lines of the welding grooves become regular, thereby improving the quality and efficiency of motor manufacturing.
