Description

Technical Field

[0001] The utility model relates to the technical field of protection devices, in particular to a protection device for shaping a motor stator coil. Background Art

[0002] The shaping of the motor stator coil is a key process in the motor production process. The stator is fixed and the coil is squeezed through the shaping mold to shape the coil to the required size. The shaping disk is the part of the shaping mold that fixes the stator. The shaping disk consists of four parts: a base, a turntable, a slide, and protective teeth. When in use, the protective teeth are inserted into the gap between the stator coil and the iron core, playing a shaping and protective role during the coil shaping.

[0003] The patent with announcement number CN218771665U proposes a segmented protection device for shaping the stator coils of a motor, comprising a base, a plurality of evenly distributed chutes opened on the upper portion of the outer surface of the base, a rotating structure movably connected to the upper end of the rotating structure, a fixed plate movably connected to the lower end of the rotating structure, and a plurality of evenly distributed protective tooth structures fixedly connected, wherein the plurality of protective tooth structures are respectively located in the plurality of chutes. The segmented protection device for shaping the stator coils of a motor described in this utility model reduces the complexity of assembly and disassembly by providing a rotating structure and a protective tooth structure, thereby improving the replacement efficiency of the protection device and reducing the intensity of manual operation. The protective teeth are provided as a segmented structure, and only the tooth tip part needs to be made and replaced when making and replacing new protective teeth, which saves time and material costs, and avoids the negative impact of repeated assembly and disassembly on positioning accuracy.

[0004] During use of the above case, since the No. 1 protective tooth and the No. 2 protective tooth are connected by a hexagonal set screw, when multiple No. 1 protective teeth are closed together to achieve the protective effect, the No. 1 protective tooth will rotate in a circle along the hexagonal set screw as the center toward the position of the No. 2 slot. Over time, this will cause wear on the edges and corners of the No. 1 protective tooth, affecting the shaping and positioning accuracy of the motor stator coil, thereby bringing inconvenience to the use of the protection device. For this reason, the present application proposes a protection device for shaping the motor stator coil. Utility Model Content
