[0001] The utility model relates to welding positioning technical field, specifically a kind of stator core laminated welding tool. BACKGROUND

[0002] Stator core, as one of the core components of motor, plays the key role of constituting magnetic flux loop and fixing stator coil. It is composed of punching sheet and various fasteners, usually made of silicon steel sheet material with good magnetic conductivity and low loss, and the thickness is generally 0.5mm or 0.35mm. These punching sheets are precisely processed and stacked to form an overall structure with good rigidity and vibration characteristics.

[0003] The stator core is made through a series of precise mechanical processing processes, including stamping or cutting process, and then the processed iron sheets are stacked in multiple layers and firmly connected together through welding technology. In the welding process, in order to ensure the accuracy of welding and the overall strength after welding, a specially designed positioning tool is needed to fix the stacked iron core. This tool can ensure that the iron core remains stable during welding and does not displace or deform. During welding, the operator needs to hold the welding gun and carefully weld along the edge of the iron core, which requires the operator to have high concentration and skilled skills. Due to the meticulousness of welding and the strict requirements for welding quality, the welding speed is usually slow. Therefore, a stator core laminated welding tool is proposed. SUMMARY
