Background In the production and manufacturing process of the motor stator, after the welding process is finished, three copper plates (wiring terminals) led out from the stator winding often generate position offset and deformation due to welding thermal stress, material internal stress release or touch in process circulation. In order to ensure that the wiring terminal can be smoothly installed and well contacted in the subsequent assembly, the spatial position of the copper plate must be corrected. At present, a rigid positioning die is generally adopted, namely a supporting block with a fixed height is arranged on a bottom plate, an operator fixes the stator by using a simple clamp after placing the stator in the positioning die, and then the copper plate is forcibly bent to the plane of the supporting block by using a manual tool (such as a nipper pliers) or a hammering mode, so that the height and the position of the copper plate are controlled. The existing correction tool still cannot meet the comprehensive production requirement of a high-quality motor in practical application, and has obvious defects. The existing rigid supporting mode lacks effective isolation protection to copper plate root (near the welding point), when bending moment is applied to the copper plate end portion, stress is very easy to transfer to the root welding point, so that the welding point is cracked or invisible hidden danger is generated, the service life of a motor is influenced, moreover, as the copper material has rebound characteristics, the copper plate is flattened by simply relying on a stop block at a fixed position, the copper plate is often rebounded to an out-of-tolerance position after being released, a floating mechanism with overpressure avoidance and elastic reset functions is lacked to eliminate rebound errors, and the copper plate has poor height consistency during mass production.
