Description

Technical Field

[0001] The utility model relates to the technical field of tooling, in particular to a lamination tooling for a rotor core. Background Art

[0002] The rotor core is composed of several stacked laminations. In the existing technology, the through holes on the laminations are aligned and sequentially mounted on the core shaft, and one of the through holes on the laminations is aligned with the positioning hole on the core shaft. After the stacking and installation is completed, the cover plate is installed on the core shaft, and then one end of the positioning pin is sequentially passed through the positioning hole on the core shaft, the through hole of the laminations, and the positioning hole on the cover plate. Then, the lamination tooling is transversely rotated to the opposite direction of the cover plate and the core shaft, and the lamination deflection angle is adjusted. After the deflection is completed, the core shaft and the cover plate are locked with bolts, and then the lamination between the core shaft and the cover plate is positioned, and then the lamination is welded. This method increases the workload of workers and reduces the efficiency of installation. Moreover, after the lamination angle is deflected, there is still a rebound force in the lamination, so that the deflection angle of the lamination on each installed core is different, and the installation consistency cannot be achieved. For this reason, a lamination tooling for a rotor core is proposed that can improve installation efficiency and production consistency. Summary of the invention
