The existing winding method cannot be wound continuously, and each stator winding is wound separately, with a large number of joints and cumbersome installation. Utility Model Content

[0043] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0044] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0046] The existing winding method cannot perform continuous winding. Each stator winding is wound separately, with a large number of joints and complicated installation.

[0047] In view of this, the utility model provides a winding tool, including a winding drum 10 and a core clamp 20, the core clamp 20 is installed on the winding drum 10; the winding drum 10 is provided with a plurality of storage slots 101 evenly distributed around its own axis, and the core clamp 20 is used to fix the core 11.

[0048] The winding tool provided by the utility model temporarily stores the wound iron core 11, i.e., the stator winding, through the storage slot 101 around the local axis of the winding tool, so that the stator windings of the same phase arranged in a ring around the axis of the motor in a motor are temporarily stored in the storage slot 101. The provision of the storage slot 101 enables the stator windings of the same phase to be wound and formed by a single wire, without the need to be wound separately and then connected in series through wiring, thereby achieving continuous winding and avoiding the problem of too many joints.

[0049] In short, since the same-phase windings are separated by a certain distance, if one wire is used for winding in the conventional way, the length of the wire connecting the adjacent windings is likely to be different, and it is easy to be deformed and damaged due to placement problems. The winding tool provided by the utility model can temporarily store the stator winding in the position when it is finally assembled to the motor, avoiding the situation of different lengths and deformation and damage of the wire. When in use, the winding drum 10 can be fixed or rotated around its own axis, so as to cooperate with related equipment to complete the winding work.

[0050] The following combination Figure 1-Figure 11 The structure and shape of the winding tool provided in this embodiment are described in detail:

[0051] The winding tool provided in this embodiment includes a winding drum 10, a core clamp 20, an auxiliary clamp 30 and a limit assembly. The winding drum 10 includes a drum body 100 and an axis unit 200. Specifically, the axis unit 200 is inserted into the drum body 100 and is coaxially arranged with the drum body 100. The core clamp 20 is connected to the axis unit 200. The core clamp 20 and the auxiliary clamp 30 are respectively clamped at both ends of the core 11 to achieve a detachable connection with the core 11. The limit assembly abuts against the auxiliary clamp 30 to achieve axial locking to ensure that the core 11 does not move axially. Figure 1 shown.

[0052] In this embodiment, the disk body 100 is provided with a storage slot 101, a temporary storage slot 102, a weight reduction slot 103 and a central through hole. Figure 5 As shown, the shaft unit 200 is inserted into the central through hole, and the temporary storage slot 102 is arranged between the storage slot 101 and the axis of the winding drum 10. Among them, the storage slot 101 and the temporary storage slot 102 can be used to store the wound windings, and the weight reduction slot 103 is a circular blind hole, such as Figure 2 As shown, a plurality of storage slots 101 are evenly distributed around the axis of the disc body 100 , a plurality of temporary storage slots 102 are evenly distributed around the axis of the disc body 100 , and a plurality of weight reduction slots 103 are evenly distributed around the axis of the disc body 100 .

[0053] In this embodiment, the shaft unit 200 includes a connecting shaft 210, a transition shaft 220, a connecting pin 230, an adapter shaft 240, a connecting key 250 and a set screw. Figure 3 , Figure 4As shown. Specifically, one end of the connecting shaft 210 is inserted into the transition shaft 220, and the other end is connected to the core clamp 20; the connecting pin 230 is inserted into the transition shaft 220 and the connecting shaft 210 along the radial direction of the transition shaft 220 at the same time, and the transition shaft 220 is inserted into the disk body 100 and connected to the disk body 100 through a key; the adapter shaft 240 is inserted into the end of the transition shaft 220 away from the connecting shaft 210, and a milling plane 241 is provided on the adapter shaft 240, and a set screw is provided along the radial direction of the transition shaft 220 and is threadedly connected to the transition shaft 220, and the end face of the set screw abuts against the milling plane 241. The adapter shaft 240 is used to connect a rotating drive member such as a fixed bracket or a motor, that is, the adapter shaft 240 can remain fixed, rotate passively, or rotate actively.

[0054] In this embodiment, the connecting shaft 210 includes a connecting block and a connecting rod. Figure 6 As shown, one end of the connecting rod is connected to the connecting block, and the other end is inserted into the transition shaft 220. Specifically, two countersunk holes 211 are provided on the connecting block, and a corresponding second threaded hole 201 is provided on the core clamp 20, and the two are connected by screws; a pin shaft hole 212 extending along its radial direction is provided on the connecting rod, and a connecting pin 230 is inserted into the pin shaft hole 212 and the transition shaft 220 at the same time to transmit torque.

[0055] In this embodiment, one end of the transition shaft 220 connected to the connecting shaft 210 is provided with four U-shaped grooves 221 evenly distributed around its axis. Figure 7 As shown, the connecting pin 230 is inserted into the U-shaped groove 221 to connect the transition shaft 220 and the connecting shaft 210, thereby realizing torque transmission. During assembly, the connecting pin 230 is inserted into the pin shaft hole 212, and then the connecting shaft 210 with the connecting pin 230 is inserted into the transition shaft 220 along the axial direction and the connecting pin 230 is aligned with the U-shaped groove 221. That is, the connecting shaft 210 and the transition shaft 220 only transmit torque, and the axial direction is not fixed. The two can be detachably connected, which is convenient for replacing the iron core 11.

[0056] In this embodiment, a first threaded hole 222 extending in the radial direction of the transition shaft 220 is formed, and a set screw is installed in the first threaded hole 222 and abuts against the milling plane 241 so that torque can be transmitted between the adapter shaft 240 and the transition shaft 220 .

[0057] In this embodiment, a key slot is provided on the central through hole of the disk body 100, a key slot is provided on the transition shaft 220, and the connecting key 250 is installed in the key slots of both to achieve key connection between the two, thereby achieving torque transmission. In addition, the connecting key 250 cooperates with the connecting shaft 210 to achieve axial positioning of the disk body 100.

[0058] In this embodiment, the two ends of the auxiliary clamp 30 are respectively provided with a clamping groove 301 and a shaft hole 302, and the shaft hole 302 is coaxial with the winding drum 10. Fig.10As shown, the limiting assembly includes a telescopic rod, which is coaxially arranged with the winding drum 10, and the extended end of the telescopic rod is extended to be inserted into the shaft hole 302, and the iron core 11 is inserted into the clamping groove 301. Similarly, the iron core clamp 20 is also provided with a clamping groove 301 for installing the iron core 11.

[0059] In an optional solution of this embodiment, the extended end of the telescopic rod can be connected to the auxiliary clamp 30 and drive the auxiliary clamp 30 to move along the axial direction of the winding drum 10, or the extended end of the telescopic rod is rotatably connected to the auxiliary clamp 30. Specifically, the telescopic rod can be a cylinder.

[0060] In this embodiment, eight storage slots 101 and four temporary storage slots 102 are provided on the winding drum 10 .

[0061] The working process of the winding tool provided in this embodiment is as follows:

[0062] When in use, the two ends of the iron core 11 are respectively inserted into the positioning grooves 301 of the iron core clamp 20 and the auxiliary clamp 30 for fixation, and then the telescopic rod is extended so that the protruding end is inserted into the shaft hole 302 and abuts against the auxiliary clamp 30, thereby completing the axial positioning, preventing axial movement of related parts and ensuring the stability of the iron core 11.

[0063] In this embodiment, the winding drum 10 can rotate around its own axis to cooperate with relevant equipment to complete winding on the iron core 11 to form a winding; the winding drum 10 can also remain stationary to fix the iron core 11 and only use winding equipment to complete the winding.

[0064] When multiple in-phase windings in the motor are evenly distributed in a ring around the motor axis, after one iron core 11 is wound, it is placed in the storage slot 101, and a new iron core 11 can be replaced for winding without cutting the wire. After the second iron core 11 is wound, it is placed in the storage slot 101 adjacent to the first one, and the remaining iron cores 11 are wound in turn to complete the winding of the in-phase windings.

[0065] When the motor is composed of adjacent and same-phase windings as one group, and multiple groups of same-phase windings are evenly distributed in a ring around the motor axis and connected in series, since the distance between the windings in one group is relatively close, the connecting wires between the two windings are relatively short. Therefore, when making the first group of windings, the wound windings of this group are temporarily placed in the temporary storage slot 102. When all the windings of this group are wound, the group of windings is taken out from the temporary storage slot 102 and placed in the storage slot 101, and then the next group of windings is wound. The number of temporary storage slots 102 is set to half of the storage slots 101, so that one temporary storage slot 102 corresponds to two storage slots 101, so that the disk body 100 has a compact structure and shortens the length of the connecting wires between the windings.

[0066] Similarly, when the distance between adjacent storage slots 101 is smaller than the distance between the storage slots 101 and the axis of the winding reel, the wound windings can be temporarily stored in the temporary storage slot 102. After the second winding is wound, the first winding is transferred to the storage slot 101, and the second winding is placed in the temporary storage slot 102. When three windings are wound, the first winding and the second winding are placed in two adjacent storage slots 101, and the third winding is placed in the temporary storage slot 102.

[0067] When adjacent and same-phase windings are grouped together and multiple groups of same-phase windings are evenly distributed in a ring around the motor axis and connected in parallel, only the temporary storage slot 102 is needed to meet the winding requirements, and a group of windings can still be stored in the storage slot 101 after winding.

[0068] A multi-element motor is a motor that divides the windings in a motor into multiple sets, each set of windings is an independently operated motor unit, so that the rated power of the motor can be adjusted within a certain range by changing the number of motor units started. The multiple sets of windings of the multi-element motor can be arranged along the axial direction of the motor or around the axis. When arranged along the axial direction, the windings in a motor unit are arranged in a ring around the axis, and multiple windings are wound on each iron core 11; when arranged around the axis, the windings in a motor unit are arranged in a fan ring structure along the circumference of the motor.

[0069] The winding tooling provided in this embodiment can realize continuous winding, reduce the number of joints, and improve the consistency of magnetic flux loss. Only two lead wires are needed for the same-phase winding, and the wiring is simple and error-prone, avoiding the problem of confusion in wiring with multiple joints and cumbersome installation. At the same time, it can save materials and avoid waste.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
