Description

Technical Field

[0001] This utility model relates to the field of motor accessories technology, specifically to a motor stator ventilation slot plate. Background Technology

[0002] The stator ventilation slot is an important component of the motor stator. Its main function is to guide the ventilation channel, ensure the heat dissipation of the motor stator, and prevent the motor from being affected by overheating. The stator ventilation slot is usually welded with ribs and other components to form a stable ventilation slot for use.

[0003] The welding assembly method prevents the ventilation slot plate from being easily disassembled. If part of it is damaged, the entire ventilation slot plate will be scrapped, which is not conducive to maintenance. Furthermore, the assembly position cannot be restricted during assembly, which can easily lead to the assembly position and angle of the parts not meeting the requirements. It is necessary to use tools such as clamps for assembly. Therefore, we proposed the motor stator ventilation slot plate to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a motor stator ventilation slot plate to solve the problems mentioned in the background art. Currently, ventilation slot plates on the market cannot be flexibly disassembled. When a part of the ventilation slot plate is damaged, the entire ventilation slot plate will be scrapped directly, which is not conducive to maintenance. Furthermore, during assembly, the assembly position cannot be limited, which easily leads to the assembly position and angle of the accessories not meeting the requirements.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a motor stator ventilation slot plate, including a ventilation slot piece, wherein a longitudinal rib is provided on the side of the ventilation slot piece, a positioning hole is provided at the end of the longitudinal rib, a limit groove is provided on the side of the longitudinal rib, and a first fastening pad and a second fastening pad are connected to the inner wall of the longitudinal rib.

[0006] A limiting plate is provided on the inner side of the limiting groove, and a positioning rod is connected to the lower side of the limiting plate. Threaded holes are provided at both the left and right ends of the limiting plate and the ventilation slot plate, and bolts are threaded onto the threaded holes.

[0007] The ventilation slot is provided with a connection hole.

[0008] Preferably, the ventilation slot is a fan-shaped structure, and longitudinal ribs are distributed at equal angles on the ventilation slot.

[0009] Preferably, the longitudinal ribs have a side "U" shaped structure, and the longitudinal ribs and ventilation slots are interlocked.

[0010] Preferably, the first and second fastening pads are symmetrically arranged about the transverse centerline of the ventilation slot, and the contact surfaces of the first and second fastening pads with the ventilation slot are distributed in an inclined manner.

[0011] Preferably, the limiting plate has an arc-shaped structure, and positioning rods are evenly distributed on the limiting plate, with the positioning rods passing through the positioning holes and connecting holes in sequence.

[0012] Preferably, the limiting plate and the limiting groove engage with each other, and the depth of the limiting groove is the same as the height of the limiting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The motor stator ventilation slot plate, by clamping the longitudinal ribs onto the ventilation slot plate and driving the longitudinal ribs to move synchronously through the positioning rod on the limit plate through the positioning hole, makes the positioning hole coincide with the connecting hole, and clamps the positioning rod into the positioning hole and the connecting hole, realizes the rapid assembly of the longitudinal ribs and the ventilation slot plate, and its disassembly is also relatively convenient, and it can be disassembled and maintained separately.

[0015] (2) When the longitudinal ribs and ventilation slots are assembled, the first and second fastening pads are deformed under pressure, so that they fit tightly against the ventilation slots, thereby increasing the friction between the longitudinal ribs and the ventilation slots and preventing the longitudinal ribs from shifting on the ventilation slots 1.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 The present invention provides the following technical solution: a motor stator ventilation slot plate, including a ventilation slot plate 1, a longitudinal rib 2 is provided on the side of the ventilation slot plate 1, a positioning hole 3 is provided at the end of the longitudinal rib 2, a limit groove 4 is provided on the side of the longitudinal rib 2, and a first fastening pad 5 and a second fastening pad 6 are connected to the inner wall of the longitudinal rib 2.

[0025] Furthermore, the ventilation slot 1 has a fan-shaped structure, and longitudinal ribs 2 are distributed at equal angles on the ventilation slot 1;

[0026] Furthermore, the longitudinal rib 2 has a side "U" shaped structure, and the longitudinal rib 2 and the ventilation slot 1 are interlocked, which facilitates the assembly of the longitudinal rib 2 and the ventilation slot 1.

[0027] Furthermore, the first fastening pad 5 and the second fastening pad 6 are symmetrically arranged about the transverse centerline of the ventilation slot 1. The contact surfaces of the first fastening pad 5 and the second fastening pad 6 with the ventilation slot 1 are distributed in an inclined manner, so that the first fastening pad 5 and the second fastening pad 6 deform and fit with the ventilation slot 1 as the longitudinal rib 2 is stretched, thereby increasing the friction between the ventilation slot 1 and the longitudinal rib 2.

[0028] A limiting plate 7 is provided on the inner side of the limiting groove 4. A positioning rod 8 is connected to the lower side of the limiting plate 7. Threaded holes 11 are provided at both the left and right ends of the limiting plate 7 and the ventilation slot 1. Bolts 10 are threadedly connected to the threaded holes 11. A connecting hole 9 is provided on the ventilation slot 1.

[0029] Furthermore, the limiting plate 7 has an arc-shaped structure, and positioning rods 8 are distributed at equal intervals on the limiting plate 7. The positioning rods 8 pass through the positioning hole 3 and the connecting hole 9 in sequence, so that the positioning rods 8 can fix the longitudinal ribs 2 and the ventilation slot plate 1, and simultaneously fix the longitudinal ribs 2 distributed at equal angles.

[0030] Furthermore, the limiting plate 7 and the limiting groove 4 engage with each other, and the depth of the limiting groove 4 is the same as the height of the limiting plate 7, so that the limiting plate 7 limits the longitudinal rib 2 and prevents the longitudinal rib 2 from shifting.

[0031] Specifically, when assembling the motor stator ventilation slot plate, the longitudinal rib 2 can be assembled onto the ventilation slot plate 1 from one end face, with the end of the longitudinal rib 2 aligned with the ventilation slot plate 1. Pushing the longitudinal rib 2 gradually engages it onto the ventilation slot plate 1. The position of the positioning hole 3 on the longitudinal rib 2 corresponds to the position of the connecting hole 9. After initially engaging the longitudinal rib 2 onto the ventilation slot plate 1, the position of the positioning rod 8 can be aligned with the position of the positioning hole 3 at the end of the longitudinal rib 2, allowing the positioning rod 8 to pass through the positioning hole 3. The moving limit plate 7 synchronously controls the movement of the longitudinal rib 2, precisely adjusting its position so that the positioning hole 3 gradually coincides with the connecting hole 9. During the movement of the longitudinal rib 2, the first fastening pad 5 and the second fastening pad 6 are deformed under pressure, tightening against the ventilation slot plate 1. The tight fit increases the friction between the longitudinal ribs 2 and the ventilation slot 1, preventing the longitudinal ribs 2 from shifting on the ventilation slot 1. Then, the limiting plate 7 is pressed down, causing the positioning rod 8 to pass through the connecting hole 9, and the limiting plate 7 to engage with the limiting groove 4, thus arranging the longitudinal ribs 2 and limiting their rotation. The limiting plate 7 then threads the bolt 10 into the threaded hole 11, locking the limiting plate 7 and the ventilation slot 1 together. This allows for rapid assembly of the ventilation slot. If a single part of the ventilation slot is damaged, the bolt 10 can be removed, driving the limiting plate 7 upwards and removing the positioning rod 8 from the connecting hole 9 and the positioning hole 3. The ventilation slot 1 and the longitudinal ribs 2 can then be disassembled and repaired. Content not described in detail in this specification is prior art known to those skilled in the art.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
