Description

Technical Field

[0001] This application relates to the field of stator core technology, and in particular to a stator core positioning mechanism. Background Technology

[0002] The stator core is a key component in a motor or generator. It is usually made of laminated silicon steel sheets. Its function is to form a magnetic circuit and fix the stator winding. It is installed inside the stator frame. When working, it generates magnetic flux through alternating magnetic field induction, thereby interacting with the rotor to realize the conversion of electrical energy and mechanical energy. When installing the stator core, a positioning mechanism is required to position it.

[0003] Currently, the relevant stator core positioning mechanisms lack multiple positioning structures and have relatively simple positioning structures, resulting in unsatisfactory positioning stability of the stator core and an inability to position the stator core more quickly and stably. Utility Model Content

[0004] To address the problems mentioned in the background art, this application provides a stator core positioning mechanism.

[0005] The stator core positioning mechanism provided in this application adopts the following technical solution:

[0006] A stator core positioning mechanism includes a stator core body, a positioning plate, and a positioning shell. The positioning shell has an inner groove, and the positioning plate is installed inside the groove. A spring is installed between the positioning plate and the positioning shell. A positioning rod is fixedly connected inside the positioning shell on the side of the positioning plate closest to the positioning plate. The stator core body is movably installed inside the positioning shell. A positioning ring is movably installed inside the positioning shell on one side of the stator core body. A limit block is fixedly connected to the periphery of the positioning ring, and a limit bolt is movably installed between the limit block and the positioning shell.

[0007] Preferably, the stator core body has a limiting groove inside, and the positioning rod is engaged with the limiting groove.

[0008] Preferably, a positioning groove is provided on one side of the interior of the positioning shell, and the limiting block is fitted into the positioning groove.

[0009] Preferably, a bolt hole is provided inside the positioning shell on one side of the positioning groove, and the limiting bolt is threadedly connected to the bolt hole.

[0010] Preferably, a protective ring is fixedly connected to the other side of the positioning shell, and a protective net is fixedly connected inside the protective ring.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] By adopting a multi-level positioning structure, the positioning rod, positioning plate, and positioning ring work together to improve the positioning stability of the stator core body through mechanical fitting and elastic clamping. The spring pre-tightening positioning plate design, combined with the precise alignment of the positioning rod, limit block, and positioning shell, improves installation efficiency. The limit bolts can be quickly locked, making it suitable for the rapid changeover requirements of motor production lines. The overall device ensures positioning efficiency and stability.

[0018] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0019] This application discloses a stator core positioning mechanism. (Refer to...) Figure 1-4A stator core positioning mechanism includes a stator core body 3, a positioning plate 4, and a positioning shell 7. A groove 5 is provided on the inner side of the positioning shell 7, and the positioning plate 4 is installed inside the groove 5. A spring 401 is installed between the positioning plate 4 and the positioning shell 7. A positioning rod 6 is fixedly connected inside the positioning shell 7 on the side of the positioning plate 4 closest to it. The stator core body 3 is movably installed inside the positioning shell 7. A positioning ring 1 is movably installed inside the positioning shell 7 on one side of the stator core body 3. A limit block 2 is fixedly connected to the periphery of the positioning ring 1. A limit bolt 201 is movably installed between the limit block 2 and the positioning shell 7. The operator installs the stator core body 3 into the interior of the positioning shell 7. The positioning rod 6 is engaged with the stator core body 3, limiting its rotation angle. At the same time, the stator core body 3 presses against the positioning plate 4, causing the spring 401 to contract. The positioning plate 4 can then press against the stator core body 3, further improving the stability of the stator core body 3's positioning. Finally, the positioning ring 1 is installed inside the positioning shell 7, so that the limiting block 2 is engaged with the positioning shell 7. The limiting bolt 201 is then screwed between the positioning ring 1 and the positioning shell 7, further limiting the position of the stator core body 3 by the positioning ring 1. This achieves rapid and stable positioning of the stator core body 3 using multiple structures, effectively improving the stability of the stator core body 3's positioning.

[0020] Reference Figure 1 The stator core body 3 has a limiting groove 301 inside, and the positioning rod 6 is engaged with the limiting groove 301. The positioning rod 6 is embedded in the limiting groove 301, which increases the friction between the stator core body 3 and the positioning shell 7 and improves the stability of the stator core body 3 installation.

[0021] Reference Figure 3 A positioning groove 8 is provided on one side inside the positioning shell 7, and the limiting block 2 is fitted into the positioning groove 8. The limiting block 2 can be embedded into the interior of the positioning groove 8, which increases the friction between the stator core body 3 and the positioning shell 7.

[0022] Reference Figure 3 The positioning shell 7 on one side of the positioning groove 8 is provided with a bolt hole 9, and the limiting bolt 201 is threadedly connected to the bolt hole 9. Screwing the limiting bolt 201 into the bolt hole 9 increases the friction between the positioning ring 1 and the positioning shell 7, thereby fixing the positioning ring 1 and the positioning shell 7 together.

[0023] Reference Figure 4 A protective ring 10 is fixedly connected to the other side of the positioning shell 7, and a protective net 1001 is fixedly connected inside the protective ring 10. The protective ring 10 and the protective net 1001 work together to protect the stator core body 3 at the end of the positioning shell 7.

[0024] The implementation principle of a stator core positioning mechanism in this application embodiment is as follows: First, the stator core body 3 is installed into the positioning shell 7, so that the positioning rod 6 is engaged with the stator core body 3 to limit the rotation angle. The stator core body 3 presses the positioning plate 4 to cause the spring 401 to contract, and the positioning plate 4 presses the stator core body 3 tightly. Then, the positioning ring 1 is installed into the positioning shell 7, so that the limiting block 2 is engaged with the positioning shell 7. Then, the limiting bolt 201 is screwed in to fix the positioning ring 1 and the positioning shell 7, thereby limiting the position of the stator core body 3 in multiple directions.

[0025] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may change.

Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
