Description

Technical Field

[0001] The utility model relates to the technical field of winding frames, in particular to a winding frame for stator production. Background Art

[0002] The motor mainly consists of distributed stator windings and a rotor. Under the action of the rotating magnetic field of the stator winding, the rotor is rotated by the magnetic field. The stator winding refers to the winding installed on the stator, that is, the copper wire wound on the stator. The winding is a general term for a phase or the entire electromagnetic circuit composed of multiple coils or coil groups. In the existing technology, the iron core is clamped on the winding frame, and the copper wire is wound around the hollow inside of the iron core through automated winding equipment.

[0003] In order to improve the stability when winding the stator winding, the prior art has made many improvements to the stator production winding frame. For example, the patent publication number CN220173077U discloses a stator production winding frame, including a fixed seat and a clamping mechanism arranged at the bottom of the fixed seat, the clamping mechanism including a sliding assembly and a rotating assembly, the sliding assembly including a clamping body, the outside of the fixed seat is provided with a clamping body, the inside of the clamping body is connected through a sliding rod, one end of the sliding rod is fixedly connected to a limiting block, the outer wall of the clamping body is fixedly connected to a cylinder, and one end of the cylinder is slidably connected to a hydraulic rod, the rotating shaft is fixed to the machine by setting, and then when the cylinder pushes the hydraulic rod forward or backward, it drives the rotating block to rotate clockwise or counterclockwise, driving the two sets of connecting rods to rotate synchronously, and pushing the two sets of clamping bodies to slide left or right on the sliding rod to clamp the fixed seat. The two sets of limit blocks can prevent the clamping body from sliding too much and falling off, thereby avoiding the problem that the clamping body cannot slide or cannot clamp the fixed seat.

[0004] The above patents have obvious beneficial effects, but still have the following deficiencies in actual operation:

[0005] In the above-mentioned comparative document, the iron core is limited and clamped by two clamps that can move toward or away from each other. In reality, the stator winding can be divided into an outer winding stator and an inner winding stator. The outer winding stator refers to the iron core with the slot facing outward, and the inner winding stator refers to the iron core with the slot facing inward. The outer winding stator is made by winding copper wire on the outside of the iron core, while the inner winding stator is made by winding copper wire on the inside of the iron core. However, in the above-mentioned comparative document, only the inner winding stator can be limited and fixed, and the fixing effect on the outer winding stator is poor, thereby reducing the scope of application of the winding frame. Therefore, this field urgently needs to make improvements to the winding frame used for stator production to solve the defects of the existing technology. Utility Model Content
