The stator coil of the three-phase asynchronous motor can be divided into a forming type and a scattered winding type, wherein the former is a coil (generally using an insulated copper bar) with a fixed shape, which is manufactured by expanding and molding equipment, and the shape, the size, the pitch and other characteristics are stable, and the latter is a coil (generally using an enameled wire) wound by a winding die, and the shape and the size of a lead of the coil can be greatly adjusted according to actual conditions. For the motor stator iron core with the center height of 280mm or less, the utility model generally adopts the scattered winding coil, and the coil length and span are adjustable, the winding is convenient and the structure is simple. The subsequent coil inserting, welding and shaping processes of the coil are very convenient and fast relative to the coil forming process, and the operability is strong.

The shaping process of the embedded wire of the stator core is an important link for manufacturing the motor and is a key process for determining the quality of the motor. The technical method and the process for inserting and shaping the motor stator core comprise the following steps: the iron core is hoisted to a roller support frame, slot bottom insulating paper, inserted lines, slot opening insulating paper, slot wedges, inserted phase insulation, the iron core is rotated to a hollow slot part until the inserted lines of all slots are finished, the iron core is automatically conveyed to a shaping position, a lead is arranged, the lead is welded, the iron core is rotated until all lines are welded, and the shaping is carried out by using an end shaping die, wherein the process has the following defects:

1. the existing iron core support frame lacks an adjusting and locking device, and when the inserting wire shaping is completed, the iron core needs to be rapidly rotated to observe the integrity of the inserting wire shaping, large thrust needs to be applied, and great labor is wasted. When the iron core needs to be rotated slowly in the shaping and wire inserting processes, force is easily applied too much, so that the phenomenon that the iron core is over-rotated when the iron core is outgoing is caused, a pushing force needs to be manually applied in the reverse direction when the iron core is rotated, the rotation speed of the iron core is controlled manually by feeling, and the iron core is inconvenient to operate and difficult to control.

The roller material of current support frame is the carbide, and the iron core rotates the in-process on the cylinder and can produce to collide with and wear, influences iron core excircle surface quality. Secondly, the contact surface of the iron core and the metal roller is too smooth, the roller can rotate when the iron core is slightly touched, and the enameled wire is easily scratched at the notch, so that the performance of the motor is influenced.

3. The shaft of the existing support frame is directly contacted with the stepped inner hole of the roller, the friction coefficient of the contact surface of the roller and the rotating shaft is large, when iron cores with different masses are supported on the same support frame, the phenomenon of overlarge friction resistance between the roller and the rotating shaft due to the large mass of the iron core can occur, so that the iron core is inconvenient to rotate, and the operation in the wire inserting and shaping processes is inconvenient; moreover, the contact surface of the rotating shaft and the roller is in long-term contact and is not smooth and stable enough, so that the contact surface of the rotating shaft and the roller is abraded frequently, and the material, labor and time cost for replacing abraded parts regularly is increased.

4. The original integrated welding between the bottom plate of the supporting plate and the workbench has poor universality and can not be adjusted according to the change of the outer diameter of the iron core.
