Description

Technical Field

[0001] This utility model relates to the field of motor testing and repair technology, and in particular to a stator-rotor separation tool. Background Technology

[0002] Before entering the stator potting process, the assembled motor components must undergo rigorous power-on testing. After the stator and rotor are mechanically assembled, they are tested. After completion, the stator is separated by mechanical pulling. The separation process mostly uses traditional puller devices. However, traditional puller devices can easily damage the surfaces of the stator and rotor, and traditional puller tools have limitations, as the puller claws cannot fit into the gaps between the stator and rotor. Utility Model Content

[0003] The purpose of this utility model is to provide a stator-rotor separation tool that can easily remove the rotor of the motor from the stator without damaging the surface of the stator and rotor, and has a wide range of applications.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] This utility model discloses a stator-rotor separation fixture, comprising: two clamping members, the middle portions of which are rotatably connected by a first pin and used to fit against the rotor of a motor to clamp the rotor; two connecting rods, one end of which is rotatably connected to the ends of the two clamping members by a second pin; and a pull rod, which passes through the two connecting rods. When an external force is applied to the pull rod, the clamping members can clamp the rotor and cause the rotor to disengage from the stator of the motor.

[0006] In some embodiments, the clamping member includes: a clamping portion having an arc-shaped clamping surface; and a connecting portion, one end of which is connected to the clamping portion and the other end of which is connected to the connecting rod.

[0007] In some specific embodiments, the clamping surface is provided with an anti-slip pad, which is used to fit against the outer wall of the rotor.

[0008] In some more specific embodiments, the anti-slip pad includes an anti-slip layer and an adhesive layer, the anti-slip layer having an anti-slip texture, and the adhesive layer being bonded to the clamping surface.

[0009] In some specific embodiments, the connecting part includes a first connecting segment and a second connecting segment, the width of the first connecting segment is greater than the width of the second connecting segment, the first connecting segment is connected to the clamping part, the second connecting segment is connected to the connecting rod, and the second connecting segments of the two clamping members are rotatably connected.

[0010] In some more specific embodiments, the first connecting segment includes a straight segment and an arc segment, the straight segment being connected to the clamping portion and the arc segment being connected to the second connecting segment.

[0011] In some specific embodiments, the second connecting segment is an arc-shaped rod.

[0012] In some embodiments, the lengths of the two portions of the pull rod located on both sides of the connecting rod are equal.

[0013] In some embodiments, both ends of the pull rod are provided with anti-slip sleeves.

[0014] In some embodiments, the first pin is provided with a first retaining ring, the head of the first pin abuts against the clamping member, and the first retaining ring abuts against the connecting rod;

[0015] The second pin is provided with a second retaining ring, and the head of the second pin and the second retaining ring respectively abut against the two clamping members.

[0016] The beneficial effects of this stator-rotor separation fixture are as follows: During the stator-rotor separation process, it is only necessary to attach the two clamping members to the outer circumferential surface of the rotor, and then pull the pull rod away from the stator. Under the action of external force, the pull rod will drive the two connecting rods to move closer to each other, causing the two clamping members to also move closer to each other to clamp the rotor. After further increasing the external force, the rotor can be separated from the stator. The clamping members, by attaching and clamping and then driving the rotor to detach, can not only facilitate the removal of the rotor from the stator, but also reduce the probability of damage to the stator and rotor. Furthermore, since the two clamping members are rotatably connected, they can adapt to the disassembly of rotors of various sizes, making the stator-rotor separation fixture highly compatible.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0023] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] In the description of this embodiment, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0025] This utility model discloses a stator and rotor separation tooling, referencing... Figure 1 and Figure 2 As shown, the stator-rotor separation fixture includes two clamping members 100, two connecting rods 300, and a pull rod 500. The middle parts of the two clamping members 100 are rotatably connected by a first pin 200 and are used to fit against the rotor 10 of the motor to clamp the rotor 10. One end of the two connecting rods 300 is rotatably connected to the end of the two clamping members 100 by a second pin 400. The pull rod 500 passes through the two connecting rods 300. When an external force is applied to the pull rod 500, the clamping members 100 can clamp the rotor 10 and drive the rotor 10 to disengage from the stator 20 of the motor.

[0026] The precise fit between the stator 20 and the rotor 10 is crucial for ensuring motor performance. After mechanical assembly, before the stator 20 is glued, the assembled motor assembly must undergo rigorous power-on testing. This testing process mainly includes the following steps: First, the assembled stator and rotor assembly is connected to a test power system. By measuring key parameters such as the no-load current, the electromagnetic performance is verified to meet design specifications. After testing, the stator and rotor need to be separated. During the separation process, the two clamping parts 100 are simply attached to the outer circumference of the rotor 10. Then, the pull rod 500 is pulled away from the stator 20. Under the action of external force, the pull rod 500 drives the two connecting rods 300 to move closer to each other, causing the two clamping parts 100 to also move closer to each other to clamp the rotor 10. As the external force is further increased, the rotor 10 can be separated from the stator 20. In this embodiment, the clamping member 100 can easily remove the rotor 10 from the stator 20 by clamping and then driving the rotor 10 to detach. This not only reduces the chance of damage to the stator 20 and the rotor 10, but also, since the two clamping members 100 are rotatably connected, they can accommodate the disassembly of rotors 10 of various sizes, making the stator-rotor separation tooling more compatible.

[0027] In some embodiments, reference Figure 1 and Figure 2 As shown, the clamping member 100 includes a clamping portion 110 and a connecting portion 120. The clamping portion 110 has an arc-shaped clamping surface. One end of the connecting portion 120 is connected to the clamping portion 110, and the other end is connected to the connecting rod 300. It can be understood that the arc-shaped clamping surface of the clamping portion 110 allows it to fit well against the outer peripheral wall of the rotor 10. This ensures that the rotor 10 is clamped, facilitating the separation of the rotor 10 from the stator 20, and also reduces the probability of damage to the rotor 10. The connecting portion 120 is used to connect with the connecting rod 300, enabling a stable rotational connection between the clamping member 100 and the connecting rod 300. Furthermore, the relatively small width of the connecting portion 120 helps reduce the overall weight of the clamping member 100, thus facilitating the use of the rotor-stator separation fixture in this embodiment.

[0028] In some specific embodiments, reference is made to Figure 1 and Figure 2 As shown, an anti-slip pad 600 is provided on the clamping surface, which is used to fit against the outer wall of the rotor 10. It can be understood that the anti-slip pad 600 on the clamping surface can increase the friction between the clamping member 100 and the outer peripheral wall of the rotor 10, thereby facilitating the separation of the rotor 10 from the stator 20.

[0029] In some more specific embodiments, the anti-slip pad 600 includes an anti-slip layer and an adhesive layer. The anti-slip layer has an anti-slip texture, and the adhesive layer is bonded to the clamping surface. It is understood that the anti-slip texture of the anti-slip layer increases the friction between the clamping member 100 and the outer peripheral wall of the rotor 10 while reducing damage to the rotor 10. The anti-slip pad 600, bonded to the clamping surface, enhances its stability, thereby facilitating the separation of the rotor 10 from the stator 20. Of course, in other embodiments of this invention, the anti-slip pad 600 can also be fixed to the clamping surface by screws or other connecting parts, or the anti-slip texture can be directly provided on the clamping surface without the anti-slip pad 600.

[0030] In some specific embodiments, reference is made to Figure 1 and Figure 2 As shown, the connecting part 120 includes a first connecting segment 121 and a second connecting segment 122. The width of the first connecting segment 121 is greater than the width of the second connecting segment 122. The first connecting segment 121 is connected to the clamping part 110, and the second connecting segment 122 is connected to the connecting rod 300. The second connecting segments 122 of the two clamping parts 100 are rotatably connected. It can be understood that the relatively large width of the first connecting part 120 can ensure a stable connection between the connecting part 120 and the clamping part 110, avoiding the phenomenon of breakage due to poor strength at the connection position between the connecting part 120 and the clamping part 110. The second connecting segment 122 is connected to the connecting rod 300, which can reduce the weight of the connecting part 120 while ensuring a stable connection with the connecting rod 300, which is beneficial to reducing the weight of the entire clamping part 100, thereby facilitating the use of the stator and rotor separation tooling of this embodiment.

[0031] In some more specific embodiments, reference is made to Figure 1 and Figure 2 As shown, the first connecting segment 121 includes a straight segment 1211 and an arc-shaped segment 1212. The straight segment 1211 is connected to the clamping part 110, and the arc-shaped segment 1212 is connected to the second connecting segment 122. It can be understood that the first connecting segment 121, including the straight segment 1211 and the arc-shaped segment 1212, can reduce the stress concentration at the connection position between the first connecting segment 121 and the second connecting segment 122, and conveniently realize that when the two connecting rods 300 rotate toward each other, the two clamping members 100 can also rotate stably toward each other.

[0032] In some specific embodiments, the second connecting segment 122 is an arc-shaped rod. This facilitates the connection between the connecting rod 300 and the first connecting segment 121, and the arc-shaped second connecting segment 122 provides better resistance to deformation, which helps extend the service life of the stator-rotor separation fixture. Of course, in other embodiments of this invention, the shape of the second connecting segment 122 can be selected according to actual needs.

[0033] In some embodiments, the two portions of the pull rod 500 located on both sides of the connecting rod 300 are of equal length. This makes it easier for the user to grip and apply force, facilitating the removal of the rotor 10 from the stator 20.

[0034] In some embodiments, both ends of the pull rod 500 are provided with anti-slip sleeves (not shown in the figure). It is understood that the added anti-slip sleeves can increase the friction between the user and the pull rod 500, making it easier for the user to pull the pull rod 500 and facilitating the removal of the rotor 10 from the stator 20.

[0035] In some embodiments, a first retaining ring (not shown) is provided on the first pin 200. The head of the first pin 200 abuts against the clamping member 100, and the first retaining ring abuts against the connecting rod 300. It is understood that the abutting of the head of the first pin 200 against the clamping member 100 and the abutting of the first retaining ring against the connecting rod 300 can prevent the first pin 200 from disengaging from the connection position between the connecting rod 300 and the clamping member 100, ensuring that the clamping member 100 and the connecting rod 300 can rotate stably, and ensuring that the rotor 10 can be removed from the stator 20 when the pull rod 500 is pulled.

[0036] In some embodiments, a second retaining ring (not shown) is provided on the second pin 400, and the head of the second pin 400 and the second retaining ring respectively abut against the two clamping members 100. It is understood that the abutment of the head of the second pin 400 and the second retaining ring against the two clamping members 100 respectively can prevent the second pin 400 from disengaging from the connection position of the two connecting rods 300, ensure that the two connecting rods 300 can rotate stably, and ensure that the rotor 10 can be removed from the stator 20 when the pull rod 500 is pulled.

[0037] In the description of this specification, references to terms such as "some embodiments," "other embodiments," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0038] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
