Description

Technical Field

[0001] The utility model relates to the technical field of motor coils, and more specifically, to a coil convenient for assembly. Background Art

[0002] During the existing motor repair process, the coil assembly process of the stator core, one of the core components of the motor, has always been a key step. Most traditional coil installation methods rely on manual operations. Specifically, workers manually push the pre-wound coils into the slots of the stator core one by one and ensure that the coils are in the correct position and fit tightly. This process is not only extremely cumbersome but also has high requirements for the skills and physical strength of workers.

[0003] Firstly, due to the precise and dense dimensions of the motor stator slots, high precision is required when manually pushing the coils to avoid coil misalignment or damage, which undoubtedly increases the difficulty of the operation. Secondly, the efficiency of manually assembling coils is low, and the installation of each coil takes a long time. Especially when facing a large number of motors to be installed, this time-consuming process directly affects the overall production speed and cost control. Moreover, long-term manual labor is likely to cause worker fatigue, which not only affects the stability of the assembly quality but may also lead to occupational health problems. No effective solution has been proposed for the problems in the related technologies. Therefore, a coil convenient for assembly is needed to solve the problems mentioned above. Summary of the Utility Model

[0004] In view of the problems in the related technologies, the utility model proposes a coil convenient for assembly to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] For this purpose, the specific technical solution adopted by the utility model is as follows:

[0006] A coil convenient for assembly includes a stator core. A plurality of coil slots are evenly opened on the inner wall of the stator core. A coil winding is fixedly installed inside the coil slots. A transmission slot is opened inside the stator core. A sliding slot one is opened on one side surface of the coil slot, and the sliding slot one is in through connection with the transmission slot. A protective shell is fixedly installed on one side of the stator core. A support ring is slidably installed inside the transmission slot. A transmission turbine is rotatably installed on the surface of the support ring. A transmission worm is meshed and connected to one side of the transmission turbine.

A threaded transmission rod is rotatably installed on the bottom surface of the protective shell, and the threaded transmission rod is rotatably connected to the positioning plate. A push rod is fixedly connected to the inner wall of the transmission turbine. The end of the push rod passes through the sliding slot one and is fixedly connected to an extrusion plate. A sliding slot two is opened on one side surface of the coil slot, and a bearing plate is slidably installed on one side of the sliding slot two.

[0007] Further, in order to achieve the sliding installation of the bearing plate on one side of the inner wall of the coil groove, a rolling wheel is rotatably installed on one side surface of the bearing plate, a limiting rod is fixedly installed on one side of the rolling wheel, and the end of the limiting rod is slidably installed on one side of the second sliding groove.

[0008] Further, in order to facilitate the screwing drive of the threaded drive rod, the top of the threaded drive rod rotatably passes through the protective housing and is fixedly connected to a screwing rod.

[0009] Further, in order to facilitate the rotation of the drive worm in the protective housing, screwing holes are opened on the upper and lower sides of the surface of the protective housing, and a screwing groove is opened on one end face of the drive worm.

[0010] Further, in order to achieve the insulation effect between the coil winding and the stator core, insulating paper is provided on both side surfaces of the coil winding.

[0012] Further, in order to achieve the frictional force when the pressing plate and the bearing plate are clamped, anti-slip patterns are provided on one side surface of both the pressing plate and the bearing plate.

[0013] The beneficial effects of the present utility model are as follows: Place one side of the coil winding to be installed in the stator core between the bearing plate and the pressing plate, rotate the drive worm to drive the drive turbine to rotate. After the drive turbine rotates, drive the pressing plate to approach the bearing plate, squeeze and clamp the coil winding. After clamping, rotate the threaded drive rod inside the protective housing, so that the threaded drive rod drives the positioning plate, the pressing plate and the bearing plate to move to the other end of the coil groove, realizing the rapid installation of the coil winding in the stator core.
