Detailed Description of the Invention

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

[0043] Such as Figures 1 to 16As shown in the figure, a motor core facilitating wire winding according to this embodiment includes a core housing 1, and both the top and bottom of the core housing 1 are of open structures; a driving ring 2 is movably provided at the bottom of the core housing 1, and the driving ring 2 is provided with a first chute 21; the bottom of the first chute 21 is wavy; each trough position of the first chute 21 is a pole body position 211; a fixed pole body 3 is provided on the inner side wall of the core housing 1, and a plurality of sliding pole bodies 4 are slidably provided; a pin 41 is movably provided at the bottom of the sliding pole body 4; the pin 41 is movably embedded in the first chute 21; a first spring 42 is provided between the pin 41 and the sliding pole body 4; coils 7 are wound around both the fixed pole body 3 and the sliding pole body 4; a fixing ring 5 for restricting the sliding pole body 4 is movably provided at the top of the core housing 1.

[0044] Specifically, in this embodiment, through the slidably provided sliding pole bodies 4, during assembly production, the distance 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 wire 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 wire materials, ensuring the smooth progress of the wire winding process, thereby adapting to the winding of different wire materials, avoiding the phenomenon of uneven wire winding or wire jamming caused by the design of a fixed wire winding space, improving the accuracy and efficiency of wire winding, and making the flexibility and adaptability in the production process higher.

[0045] For the convenience of explaining this embodiment, each sliding pole body 4 is numbered in sequence as 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 around the fixed pole body 3; after the fixed pole body 3 is wound, the fixed pole body 3 and each sliding pole body 4 are stacked together in sequence, as Figure 4 shown. At this time, the distance between the pole body L1 and the fixed pole body 3 is the farthest, and the pole body Ln abuts against 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 around 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 moved away from the pole body L2, and then the coil 7 is wound around the pole body L2. In this way, during the repeated above operation process, the distance between the sliding pole bodies 4 is adjusted, and the coil 7 is wound around the remaining sliding pole bodies 4;

[0046] After the coil 7 is wound, as Figure 5 shown, the positions of the sliding pole bodies 4 are adjusted so that each sliding pole body 4 is equally spaced in the circumferential direction, and the pins 41 of each sliding pole body 4 are respectively and correspondingly inserted into the corresponding pole body positions 211, thereby positioning the sliding pole bodies 4, as Figure 6 shown;

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

[0048] As Figure 3 shown, for the motor iron core facilitating winding in this embodiment, in some embodiments, limiting pins 43 are convexly provided at the tops of both the fixed pole body 3 and the sliding pole body 4; limiting cylinders 51 are circumferentially and uniformly distributed on the fixing ring 5 for corresponding cooperation with each of the limiting pins 43 one by one. Specifically, after the coil 7 is wound, by pressing the fixing ring 5, each of the limiting cylinders 51 is sleeved on the outer periphery of the corresponding limiting pin 43 one by one, thereby fixing the positions of the fixed pole body 3 and the sliding pole body 4.

[0049] As Figure 3 shown, for the motor iron core facilitating winding in this embodiment, in some embodiments, a friction ring 6 is provided at the top of the iron core housing 1; the limiting cylinder 51 movably penetrates through the friction ring 6. In this embodiment, by providing the friction ring 6, the friction force for the up-and-down movement of the fixing ring 5 is increased to avoid the fixing ring 5 affecting the position adjustment of the sliding pole body 4 during the winding process of the coil 7, and the structural reliability is higher; at the same time, after the coil 7 is wound, the friction ring 6 is used to more reliably fix the positions of the sliding pole body 4 and the fixed pole body 3 by the fixing ring 5, and it is not easy to loosen.

[0050] As Figure 3 and Figure 14 shown, for the motor iron core facilitating winding in this embodiment, in some embodiments, a second chute 11 is provided on the inner top wall of the iron core housing 1; the limiting pin 43 is movably embedded in the second chute 11; the friction ring 6 is provided at the bottom of the second chute 11. In this embodiment, by providing the second chute 11, it provides guidance and limitation for the limiting pin 43 and also facilitates the installation of the friction ring 6.

[0051] As Figure 3 and Figure 14 shown, for the motor iron core facilitating winding in this embodiment, in some embodiments, a third chute 12 is provided at the top of the iron core housing 1; the fixing ring 5 is arranged to be lifted and lowered in the third chute 12; each of the limiting cylinders 51 movably extends into the second chute 11. In this embodiment, by providing the third chute 12, it limits and guides the fixing ring 5 and also facilitates the installation of the fixing ring 5.

[0052] As Figure 2 、 Figures 7 to 16As shown, for the motor iron core facilitating wire winding in this embodiment, in some embodiments, a driving block 22 is movably inserted through the peak position of the first sliding groove 21 of the driving ring 2; a second spring 23 is provided between the driving block 22 and the driving ring 2; a guiding surface is provided on the driving block 22 and / or the latch 41; the tangent inclination angle of the contact point when the driving block 22 contacts the latch 41 is θ; wherein, as Figure 16 shown, the elastic force F of the first spring 42 弹 satisfies the following relational expression: f m ﹤F 弹 tanθ﹤2f m ; f m is the sliding friction force received when a single sliding pole body 4 slides;

[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 iron core housing 1 is provided with a locking groove 13 for unidirectional locking cooperation with the locking block 24; the iron core housing 1 is further provided with a guiding sliding groove 14 located below the locking groove 13 and for sliding cooperation with the locking block 24.

[0054] Exemplarily, when a guiding surface is provided on the latch 41, the guiding surface can be an arc chamfer surface or an inclined surface; when a guiding surface is provided on the driving block 22, the guiding surface can be an arc chamfer surface or an inclined surface; specifically, it can be set according to actual design requirements.

[0055] Specifically, initially, the locking block 24 is located in the guiding sliding groove 14, and the iron core housing 1 presses the driving block 22, so that the driving block 22 compresses the second spring 23 and protrudes upward from the bottom of the first sliding groove 21; when adjusting the distance 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, the driving ring 2 drives the driving block 22 to rotate clockwise, and the locking block 24 moves along the guiding sliding groove 14. Since there is a frictional force between the sliding pole body 4 and the iron core housing 1, and the elastic force F of the first spring 42 弹 is greater than the sliding friction force f received when a single sliding pole body 4 slides m , and is less than the sum of the sliding friction forces f received by two sliding pole bodies 4 m , that is, when the driving block 22 contacts the latch 41 of the sliding pole body 4, if the driving block 22 pushes a single sliding pole body 4 to slide, at this time the driving block 22 pushes a single sliding pole body 4 to slide through the latch 41, that is, the elastic force F exerted by the first spring 42 on the latch 41 弹 is greater than the sliding friction force f received by a single sliding pole body 4 m , so that the driving block 22 pushes a single sliding pole body 4 to slide through the latch 41; if the driving block 22 pushes two or more sliding pole bodies 4 to slide, since the elastic force F exerted by the first spring 42 on the latch 41 弹Greater than the sliding friction force f of a single sliding pole body 4 m , and less than the sum of the sliding friction forces f of two sliding pole bodies 4 m , so that the driving block 22 cannot push two or more sliding pole bodies 4 to slide simultaneously. At this time, the driving block 22 squeezes the corresponding detent pin 41 with which it contacts, causing the corresponding first spring 42 to compress until the driving block 22 passes over the detent pin 41, and then the driving block 22 rotates to contact the detent pin 41 of the next sliding pole body 4; and so on until the driving block 22 pushes a single sliding pole body 4 to slide.

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

[0057] After the coil 7 is wound, stack each sliding pole body 4 together in the clockwise direction, and then press the driving ring 2 upward. The locking block 24 is squeezed and retracts against the elastic force of the third spring 25, so that the locking block 24 moves out of the guiding chute 14 and snaps into the locking groove 13. The locking block 24 and the locking groove 13 cooperate to form an anti-reverse 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. Then rotate the driving ring 2 counterclockwise. The driving ring 2 drives the driving block 22 to rotate counterclockwise. At this time, since the driving block 22 is in the retracted state, it will not generate a thrust on the detent pin 41. When the detent pin 41 of the pole body Ln corresponds to the pole body position 211 of the first chute 21, the corresponding first spring 42 pushes the detent pin 41 to insert into the corresponding pole body position 211. At this time, under the cooperation of the detent pin 41 and the pole body position 211, the driving ring 2 drives the pole body Ln to rotate counterclockwise. When the pole body Ln-1 corresponds to the next pole body position 211, the corresponding first spring 42 pushes the detent pin 41 to insert into the corresponding pole body position 211. At this time, the driving ring 2 drives the pole body Ln and the pole body Ln-1 to rotate counterclockwise simultaneously. In this way, as the driving ring 2 rotates counterclockwise, the detent pins 41 of each sliding pole body 4 are sequentially snapped into the corresponding pole body positions 211, so that each sliding pole body 4 is equally spaced; then, press the fixing ring 5 downward so that each limiting cylinder 51 is sleeved on the outer periphery of the corresponding limiting pin 43 one by one, thereby fixing the positions of each sliding pole body 4 and restricting the sliding of the sliding pole body 4, thus completing the winding and installation of the iron core coil 7.

[0058] Such as Figure 15As shown, for the motor core facilitating wire winding in this embodiment, in some embodiments, the locking groove 13 is composed of a plurality of groove units evenly arranged circumferentially; the guiding sliding groove 14 is an annular groove. Specifically, when the driving ring 2 is rotated counterclockwise, the locking block 24 is successively engaged into the groove units under the elastic force of the third spring 25, and the cooperation between the locking block 24 and the groove units prevents the driving ring 2 from rotating clockwise. During the wire 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 driving ring 2.

[0059] As Figure 2 , Figures 7 to 15 As shown, for the motor core facilitating wire winding in this embodiment, in some embodiments, a first ring platform 15 is provided at the bottom of the core housing 1; the driving ring 2 is provided with a first ring groove 26; the first ring platform 15 is rotationally connected to the first ring groove 26; the driving block 22 abuts against the top surface of the first ring platform 15; the driving ring 2 horizontally extends a second ring platform 27 above the first ring groove 26; the first sliding groove 21 is provided on the top surface of the second ring platform 27; the driving block 22 movably penetrates through the second ring platform 27. In this embodiment, by providing the first ring groove 26 to cooperate with the first ring body, the stability of the rotation of the driving ring 2 is enhanced; initially, the locking block 24 is located in the guiding sliding 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 driving block 22 upward, causing the second spring 23 to be compressed, so that the driving block 22 protrudes upward from the bottom of the first sliding groove 21 to push the sliding pole body 4 to slide circumferentially through the pin 41;

[0060] When the driving ring 2 is pressed upward so that the locking block 24 overcomes the elastic force of the third spring 25 and is engaged into the locking groove 13, the distance between the second ring platform 27 and the first ring platform 15 increases. At this time, the second spring 23 resets and pushes the driving block 22 to move downward relative to the driving ring 2, so that the driving block 22 is in a contracted state.

[0061] As Figure 2 , Figures 7 to 11 , Figure 15 As shown, for the motor core facilitating wire winding in this embodiment, in some embodiments, a second ring groove 16 is provided outside the first ring platform 15 at the bottom of the core housing 1; the driving ring 2 vertically extends a third ring platform 28 outside the first ring groove 26; the third ring platform 28 is rotationally connected to the second ring groove 16; the locking block 24 is movably provided on the outer side wall of the third ring platform 28; the locking groove 13 and the guiding sliding groove 14 are provided on the side groove wall of the second ring groove 16. In this embodiment, by providing the third ring platform 28, it is convenient for the installation of the locking block 24. Through the cooperation between the third ring platform 28 and the second ring groove 16, the stability between the driving ring 2 and the core housing 1 is further enhanced.

[0062] The above are only the preferred embodiments of the present invention. Therefore, equivalent changes or modifications made according to the structures, features and principles described in the scope of the patent application of the present invention are included in the protection scope of the patent application of the present invention.
