DETAILED DESCRIPTION

[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the implementation scope of the present invention is not limited thereto.

[0043] like Figures 1 to 16As shown, a motor core that is easy to wind described in this embodiment includes a core shell 1, and the top and bottom of the core shell 1 are both open structures; a driving ring 2 is movably provided at the bottom of the core shell 1, and the driving ring 2 is provided with a first slide groove 21; the groove bottom of the first slide groove 21 is wavy; each trough position of the first slide groove 21 is a pole body position 211; the inner side wall of the core shell 1 is provided with a fixed pole body 3 and a plurality of sliding pole bodies 4 are slidably provided; a bayonet 41 is movably provided at the bottom of the sliding pole body 4; the bayonet 41 is movably embedded in the first slide groove 21; a first spring 42 is provided between the bayonet 41 and the sliding pole body 4; a coil 7 is wound on both the fixed pole body 3 and the sliding pole body 4; a fixing ring 5 for limiting the sliding pole body 4 is movably provided on the top of the core shell 1.

[0044] Specifically, the present embodiment uses a sliding pole body 4 that is slidably arranged, so that during assembly production, the spacing between adjacent sliding pole bodies 4 and between the sliding pole body 4 and the fixed pole body 3 can be adjusted, so that the winding space size of the sliding pole body 4 and the fixed pole body 3 can be flexibly adjusted according to the specifications and shapes of different wires to ensure a smooth winding process, thereby being able to adapt to the winding of different wires, avoiding the phenomenon of uneven winding or wire jamming due to a fixed winding space design, improving the winding accuracy and efficiency, and making the production process more flexible and adaptable.

[0045] In order to facilitate the explanation of this embodiment, each sliding pole body 4 is numbered, and is sequentially pole body L1, pole body L2, pole body L3, ... pole body Ln; during production, the sliding pole body 4 is slid to a position opposite to the fixed pole body 3, and then the coil 7 is wound on the fixed pole body 3; after the winding of the fixed pole body 3 is completed, the fixed pole body 3 and each sliding pole body 4 are stacked together in sequence, as shown in FIG. Figure 4 As shown, at this time, the pole body L1 is farthest from the fixed pole body 3, and the pole body Ln is close to the fixed pole body 3; then the pole body L1 is slid to a position opposite to the fixed pole body 3, so that there is a large operating space on both sides of the pole body L1, and then the coil 7 is wound on the pole body L1; the pole body L2 is slid to a position opposite to the fixed pole body 3, and the wound pole body L1 is kept away from the pole body L2, and then the coil 7 is wound on the pole body L2, and the above-mentioned action is repeated, and the distance between the sliding pole bodies 4 and the sliding pole bodies 4 is adjusted, and the coil 7 is wound on the remaining sliding pole bodies 4;

[0046] The coil 7 is wound, as shown in FIG. Figure 5 As shown, the position of the sliding pole body 4 is adjusted so that each sliding pole body 4 is evenly spaced along the circumferential direction, and the latches 41 of each sliding pole body 4 are respectively snapped into the corresponding pole body position 211 one by one, so as to position the sliding pole body 4, as shown in FIG. Figure 6 As shown;

[0047] Then, the fixing ring 5 is pressed to restrict each sliding pole body 4 through the fixing ring 5 so that each sliding pole body 4 is fixed at the current position, thus completing the winding installation of the core coil 7.

[0048] like Figure 3 As shown, in the motor core of this embodiment that is convenient for winding, in some embodiments, the tops of the fixed pole body 3 and the sliding pole body 4 are both convexly provided with a stop pin 43; the fixed ring 5 is evenly distributed along the circumference with stop cylinders 51 for one-to-one matching with each stop pin 43. Specifically, after the coil 7 is wound, by pressing the fixed ring 5, each stop cylinder 51 is one-to-one correspondingly inserted into the outer circumference of the corresponding stop pin 43, thereby fixing the position of the fixed pole body 3 and the sliding pole body 4.

[0049] like Figure 3 As shown, in the motor core of this embodiment that is convenient for winding, in some implementations, a friction ring 6 is provided on the top of the core housing 1; the limiting cylinder 51 movably penetrates the friction ring 6. In this embodiment, the friction ring 6 is provided to increase the friction force of the fixed ring 5 moving up and down, so as to avoid the fixed ring 5 affecting the position adjustment of the sliding pole body 4 during the winding of the coil 7, and the structural reliability is higher; at the same time, after the winding of the coil 7 is completed, the friction ring 6 is used to make the fixed ring 5 more reliably fix the position of the sliding pole body 4 and the fixed pole body 3, and it is not easy to loosen.

[0050] like Figure 3 and Fig.14 As shown, in the motor core of this embodiment which is convenient for winding, in some embodiments, the inner top wall of the core housing 1 is provided with a second slide groove 11; the limit pin 43 is movably embedded in the second slide groove 11; and the friction ring 6 is arranged at the bottom of the second slide groove 11. In this embodiment, the second slide groove 11 is provided to provide guidance and limit for the limit pin 43, and also facilitates the installation of the friction ring 6.

[0051] like Figure 3 and Fig.14 As shown, in the motor core of this embodiment that is convenient for winding, in some embodiments, a third slide groove 12 is provided on the top of the core housing 1; the fixing ring 5 is lifted and lowered in the third slide groove 12; each of the limiting cylinders 51 is movably extended into the second slide groove 11. In this embodiment, the third slide groove 12 is provided to limit and guide the fixing ring 5, and the installation of the fixing ring 5 is also facilitated.

[0052] like Figure 2 , Figures 7 to 16As shown, in the motor core of this embodiment which is convenient for winding, in some embodiments, the drive ring 2 is provided with a drive block 22 movably inserted at the wave crest position of the first slide groove 21; a second spring 23 is provided between the drive block 22 and the drive ring 2; the drive block 22 and / or the bayonet 41 are provided with a guide surface; the tangent inclination angle of the contact point when the drive block 22 contacts the bayonet 41 is θ; wherein, Fig.16 As shown, the elastic force F of the first spring 42 弹 Satisfies the following relationship: m ﹤F 弹 tanθ﹤2f m ;f m is the sliding friction force received by a single sliding pole body 4 when sliding;

[0053] A locking block 24 is movably provided on the side wall of the driving ring 2; a third spring 25 is provided between the locking block 24 and the driving ring 2; the core housing 1 is provided with a locking groove 13 for one-way locking cooperation with the locking block 24; the core housing 1 is also provided with a guide groove 14 located below the locking groove 13 and for sliding cooperation with the locking block 24.

[0054] Exemplarily, when a guide surface is provided on the detent 41, the guide surface may be a circular chamfered surface or an inclined surface; when a guide surface is provided on the driving block 22, the guide surface may be a circular chamfered surface or an inclined surface; the specific setting may be made according to actual design requirements.

[0055] Specifically, initially, the locking block 24 is located in the guide slot 14, and the core housing 1 squeezes the driving block 22, so that the driving block 22 compresses the second spring 23 and protrudes upward from the bottom of the first slot 21; when adjusting the spacing between the sliding pole bodies 4 and between the sliding pole body 4 and the fixed pole body 3, the driving ring 2 is rotated clockwise, and the driving ring 2 drives the driving block 22 to rotate clockwise, and the locking block 24 moves along the guide slot 14. Due to the friction between the sliding pole body 4 and the core housing 1, the elastic force F of the first spring 42 弹 Greater than the sliding friction force f that a single sliding pole body 4 experiences when sliding m , and is less than the sliding friction force f m The sum of the ... 弹 Greater than the sliding friction force f of a single sliding pole body 4 m , so that the driving block 22 pushes a single sliding pole body 4 to slide through the bayonet 41; if the driving block 22 pushes two or more sliding pole bodies 4 to slide, due to the elastic force F exerted by the first spring 42 on the bayonet 41 弹Greater than the sliding friction force f of a single sliding pole body 4 m , and is less than the sliding friction force f m The sum of the two makes it impossible for the driving block 22 to push two or more sliding pole bodies 4 to slide at the same time. At this time, the driving block 22 squeezes the latch 41 in contact with it, so that the corresponding first spring 42 is compressed until the driving block 22 passes over the latch 41, and then the driving block 22 rotates to contact the latch 41 of the next sliding pole body 4; this continues until the driving block 22 pushes a single sliding pole body 4 to slide.

[0056] That is to say, in this embodiment, the position of each sliding pole body 4 can be adjusted by repeatedly rotating the driving ring 2 for multiple turns, thereby adjusting the winding space so that the winding operation has sufficient operating space.

[0057] After the coil 7 is wound, the sliding pole bodies 4 are stacked together in sequence in the clockwise direction, and then the driving ring 2 is pressed upward, the locking block 24 is squeezed and overcomes the elastic force of the third spring 25 to retract, so that the locking block 24 moves out of the guide slot 14 and is stuck in the locking slot 13. The locking block 24 cooperates with the locking slot 13 to form an anti-reversal mechanism. At this time, the second spring 23 restores its elastic deformation, pushing the driving block 22 to retract downward relative to the driving ring 2, and then the driving ring 2 is rotated counterclockwise. The driving ring 2 drives the driving block 22 to rotate counterclockwise. At this time, since the driving block 22 is in a retracted state, it will not generate a thrust on the bayonet 41. At this time, when the bayonet 41 of the pole body Ln corresponds to the pole body position 211 of the first slot 21, the corresponding first spring 42 pushes the bayonet 41 to be inserted into the corresponding The corresponding pole body position 211, at this time, with the cooperation of the latch 41 and the pole body position 211, the driving ring 2 drives the pole body Ln to rotate counterclockwise, and when the pole body Ln-1 corresponds to the next pole body position 211, the corresponding first spring 42 pushes the latch 41 to be inserted into the corresponding pole body position 211, and the driving ring 2 drives the pole body Ln and the pole body Ln-1 to rotate counterclockwise at the same time. As the driving ring 2 rotates counterclockwise, the latch 41 of each sliding pole body 4 is sequentially inserted into the corresponding pole body position 211, so that each sliding pole body 4 is evenly spaced; then, the fixing ring 5 is pressed downward, so that each limiting cylinder 51 is correspondingly inserted into the outer periphery of the corresponding limiting pin 43, thereby fixing the position of each sliding pole body 4 and limiting the sliding of the sliding pole body 4, thereby completing the winding installation of the iron core coil 7.

[0058] like Fig.15As shown, in the motor core of this embodiment that is convenient for winding, in some embodiments, the locking groove 13 is composed of a plurality of groove units evenly arranged along the circumferential direction; the guide groove 14 is an annular groove. Specifically, when the drive ring 2 rotates counterclockwise, the locking block 24 is sequentially inserted into the groove unit under the elastic force of the third spring 25, and the locking block 24 cooperates with the groove unit to prevent the drive ring 2 from rotating clockwise. During the winding process of the coil 7, the locking block 24 moves along the trajectory of the annular groove, thereby providing guidance and limitation for the rotational movement of the drive ring 2.

[0059] like Figure 2 , Figures 7 to 15 As shown, in some embodiments of the motor core for winding of this embodiment, the bottom of the core housing 1 is provided with a first ring platform 15; the drive ring 2 is provided with a first ring groove 26; the first ring platform 15 is rotatably connected with the first ring groove 26; the drive block 22 is in contact with the top surface of the first ring platform 15; the drive ring 2 is horizontally extended with a second ring platform 27 above the first ring groove 26; the first slide groove 21 is provided on the top surface of the second ring platform 27; the drive block 22 is movably provided on the second ring platform 27. In this embodiment, the first ring groove 26 is provided to cooperate with the first ring body, thereby enhancing the stability of the rotation of the drive ring 2; at the beginning, the locking block 24 is located in the guide slide groove 14, and the distance between the first ring platform 15 and the second ring platform 27 is the smallest, that is, the first ring platform 15 presses the drive block 22 upward, so that the second spring 23 is compressed, so that the drive block 22 protrudes upward from the bottom of the first slide groove 21, so as to push the sliding pole body 4 to slide along the circumferential direction through the bayonet 41;

[0060] When the drive ring 2 is pressed upward so that the locking block 24 overcomes the elastic force of the third spring 25 and is stuck in the locking groove 13, the distance between the second ring stage 27 and the first ring stage 15 increases. At this time, the second spring 23 is reset, pushing the drive block 22 to move downward relative to the drive ring 2, so that the drive block 22 is in a retracted state.

[0061] like Figure 2 , Figures 7 to 11 , Fig.15 As shown, in the motor core of this embodiment that is convenient for winding, in some embodiments, the bottom of the core housing 1 is provided with a second annular groove 16 on the outside of the first annular platform 15; the drive ring 2 is vertically extended with a third annular platform 28 on the outside of the first annular groove 26; the third annular platform 28 is rotatably connected with the second annular groove 16; the locking block 24 is movably provided on the outer side wall of the third annular platform 28; the locking groove 13 and the guide slide groove 14 are provided on the side groove wall of the second annular groove 16. In this embodiment, the third annular platform 28 is provided to facilitate the installation of the locking block 24, and the third annular platform 28 cooperates with the second annular groove 16 to further enhance the stability between the drive ring 2 and the core housing 1.
