Description

Technical Field

[0001] The utility model relates to the technical field of motor processing, and in particular to a hard winding coil precision positioning plug-in device. Background Art

[0002] The connection between the flat wire hairpin coil and the stator core is an important component step of the hairpin motor. The hairpin motor is a stator winding shaped like a hairpin. During the production process of the hairpin motor, the hairpin-shaped copper wire winding needs to be pressed into the motor. The hairpin motor is also a flat copper wire motor. The hairpin motor is threaded and then the end of each turn is welded. The number of heads in each slot is equal to twice the number of turns. The traditional flat copper wire motor directly puts the formed winding into the slot. Each slot has only two heads. The existing hairpin motor is currently mainly used in new energy vehicles, and the design is mainly based on permanent magnet motors.

[0003] For example, the automatic pressing device for flat wire hairpin coils and stator cores disclosed in the authorization announcement number CN218276414U can prevent the displacement of the core due to excessive or insufficient pressure, and achieve accurate positioning of the core. However, the structural stability of the device for plugging the coil into the core is poor, and the accuracy of the plugging cannot be guaranteed, which has great limitations. At present, some plug-ins are also manually plugged in. Manual operation is labor-intensive, time-consuming and labor-intensive, and is not conducive to mass production. Utility Model Content
