Technical Field
[0001] This utility model relates to the field of stator frame technology, and more specifically to a stator frame assembly. Background Technology
[0002] Stator frame assemblies are core components in electromagnetic equipment such as motors and transformers. They are mainly used to support and fix stator windings, ensuring the efficient transmission of insulation, mechanical stability, and electromagnetic performance between the windings and the core. With the increasing demands on motor performance in fields such as industrial automation, new energy vehicles, and precision servo systems, the design optimization of stator frame assemblies has become a key technology direction for improving equipment efficiency, reliability, and miniaturization.
[0003] A search revealed Chinese patent CN217362708U, which discloses a stator frame for a three-phase asynchronous motor. This device, through the arrangement of a first slot, a second slot, and a coil frame, facilitates the installation of the coil frame onto the stator frame body. The coil frame can be fixed onto the stator frame body through the arrangement of a plug rod and a plug hole. However, when the coil frame is disassembled or assembled by moving the movable plate, the small gaps between the multiple coil frames greatly affect the operator's operation of the movable plate, making the replacement of the coil frame quite difficult.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] Reference Figures 1-6This utility model provides a stator frame assembly, including a stator frame body 1. A mounting base 2 is bolted to the bottom of the stator frame body 1. Multiple coil slots 3 arranged in a circular array are formed on the top of the stator frame body 1. Coil frames 4 are slidably connected to each of the coil slots 3. The corresponding coil frame 4 can be removed by moving it upwards, and then a new coil frame 4 can be installed into the corresponding coil slot 3. Multiple arc-shaped slots 5, each communicating with the coil slots 3 and arranged in a circular array, are formed inside the stator frame body 1. Multiple fan-shaped slots 6, which cooperate with the arc-shaped slots 5, are formed on the outer circumference of the stator frame body 1. Arc-shaped sliders 7 are slidably connected to the arc-shaped slots 5. A locking block 8 is welded to one end of the arc-shaped slider 7. A locking groove 9, which cooperates with the locking block 8, is formed on one side of the coil frame 4. A fan-shaped slot 6 is slidably connected to... The sector block 10, by setting the sector block 10 on the outer circumference of the stator frame body 1, avoids the problem of the narrow gap between the coil frames 4, which affects the movement of the sector block 10 and makes the replacement of the coil frames 4 difficult. The structure is simple and easy to operate. One end of the sector block 10 is fixed to one side of the arc-shaped slide bar 7, and the other end of the sector block 10 protrudes to the outside of the stator frame body 1. When in use, the sector block 10 is moved to slide counterclockwise along the sector groove 6. During the movement of the sector block 10, the arc-shaped slide bar 7 at its end will slide counterclockwise along the arc groove 5. During the movement of the arc-shaped slide bar 7, the locking block 8 at its end will gradually disengage from the locking groove 9. After the two are completely disengaged, the sector block 10 is moved to make one side contact the inner wall of one side of the sector groove 6. At this time, the sliding plate 15 is released, and the spring is activated.
[0024] In this utility model, a columnar groove 11 is provided on one side of the inner wall of multiple fan-shaped grooves 6. A spring 12 is welded on one side of the inner wall of the columnar groove 11, and the other end of the spring 12 is fixed to one side of the fan-shaped block 10. During its reset process, the continuous pressure of the spring 12 forces the locking block 9 to be tightly embedded in the locking groove 8, forming a reliable mechanical lock. The tight cooperation between them can prevent accidental disengagement caused by vibration, impact or external force, and enhance their stability.
[0025] In this invention, a groove 13 is provided on one side of each of the multiple fan-shaped blocks 10. A sliding plate 15 is slidably connected within the groove 13. A spring 16 is welded between the lower surface of the sliding plate 15 and the bottom inner wall of the groove 13. A locking post 17 is welded to the upper surface of the sliding plate 15. A positioning groove 18 is provided on the top inner wall of the fan-shaped block 10 to cooperate with the locking post 17. Through the cooperation of the locking post 17 and the positioning groove 18, the locking post 17 can be embedded into the positioning groove 18 when the fan-shaped block 10 is moved to one side of the fan-shaped groove 6. It is not necessary to manually apply force to the fan-shaped block 10 to maintain its state, thus reducing the burden on the workers. The lower surface of the sliding plate 15 is open to the airflow. A limiting slide rod 14 is fixedly connected by bolts. The limiting slide rod 14 is inserted into the sector block 10 and slidably connected to it. When the coil frame 4 needs to be replaced, first press the slide plate 15 on the sector block 10 to move it downward. At this time, the second spring 16 is compressed. After the coil frame 4 is replaced, press the slide plate 15 downward to disengage the locking post 17 and positioning groove 18 on it. At this time, the first spring 12 releases its elastic force to push the sector block 10 to move in the opposite direction along the sector groove 6. At the same time, the arc-shaped slide bar 7 slides in the opposite direction along the arc groove 5. The locking block 8 at one end is re-embedded into the locking groove 9 on the coil frame 4. Then, release the slide plate 15 to complete the replacement of the coil frame 4.
[0026] In this utility model, the stator frame body 1 is composed of two parts, namely the upper part and the lower part. Its cross section is located at the middle position of the height of the fan-shaped groove 6. The mounting base 2 is provided with at least four mounting holes, and the four mounting holes are respectively located at the four corners of the mounting base 2.
[0027] The use of this utility model involves the following steps:
[0028] S1: When it is necessary to replace the coil frame 4, first press the slide plate 15 on the fan-shaped block 10 to move it downward. At this time, the spring 16 is compressed.
[0029] S2: Then move the sector block 10 to slide counterclockwise along the sector groove 6. During the movement of the sector block 10, it will drive the arc-shaped slider 7 at its end to slide counterclockwise along the arc groove 5. During the movement of the arc-shaped slider 7, the locking block 8 at its end will gradually disengage from the locking groove 9. After the two are completely disengaged, continue to move the sector block 10 so that one side contacts the inner wall of the sector groove 6. At this time, release the slide plate 15. At this time, the spring 16 releases its elastic force to push the slide plate 15 upward, and at the same time, the locking post 17 on it is embedded in the positioning groove 18.
[0030] S3: Then move the corresponding coil holder 4 upward to remove it. Then replace it with a new coil holder 4 and install it into the corresponding coil slot 3. After installation, press down on the slide plate 15 to disengage the locking post 17 and positioning slot 18. At this time, the spring 12 releases its elastic force to push the fan-shaped block 10 to move in the opposite direction along the fan-shaped slot 6. At the same time, the arc-shaped slide bar 7 slides in the opposite direction along the arc-shaped slot 5. The locking block 8 at one end is re-embedded into the locking slot 9 on the coil holder 4. Then release the slide plate 15 to complete the replacement of the coil holder 4.
