TECHNICAL FIELD

[0001] The present application belongs to the technical field of motor equipment, and particularly relates to a torsion forming mechanism. BACKGROUND

[0002] In the process of assembling the motor, the copper wire on the stator core needs to be bent. The current torsion mechanism is prone to copper wire disorder and slot paper damage after the copper wire is bent, which affects the product quality of the motor. SUMMARY

[0003] The present application aims to solve one of the problems in the prior art or related art.

[0004] Therefore, the present application provides a torsion forming mechanism for torsion of the copper wire on the stator core. The torsion forming mechanism comprises a base assembly, a clamping assembly arranged on the base assembly and used for clamping the stator core, a radial motion assembly arranged on the base assembly and comprising a plurality of sliding assemblies capable of moving along the radial direction of the stator core to extend between two groups of copper wires distributed in the circumferential direction and located between adjacent two groups of slot papers, and a torsion assembly arranged on the base assembly and used for torsion of the copper wire.

[0005] The torsion forming mechanism provided by the present application is used for torsion of the copper wire on the stator core to a preset angle. The torsion forming mechanism comprises a base assembly, a clamping assembly and a radial motion assembly. The base assembly serves as a bearing for the clamping assembly and the radial motion assembly. The clamping assembly and the radial motion assembly are installed on the same bearing part, so that the relative position of the clamping assembly and the radial motion assembly will not change, thereby improving the stability of the torsion process. The clamping assembly can clamp the stator core to prevent the stator core from shaking. The torsion assembly can torsion the copper wire to automatically complete the bending process of the copper wire.

[0006] Specifically, when the copper wire needs to be torsioned, the stator core assembled with the copper wire can be transferred to the clamping assembly by a tool, for example, the stator core assembled with the copper wire is transferred to the clamping station of the clamping assembly by a mechanical hand. The clamping assembly can clamp the stator core. In the process of bending the copper wire, the copper wire will be subjected to a pulling force, so that the stator core is subjected to an axial tension. In order to improve the stability of the copper wire bending process, the stator core is clamped by the clamping assembly, so that the position of the stator core is not easy to change, and therefore the position of the copper wire on the stator core is not easy to change, ensuring that the torsion assembly can stably bend the copper wire.

[0007] The sliding assembly in the radial movement assembly can move along the radial direction of the stator core, and can extend into the space between two groups of copper wires distributed along the circumferential direction of the stator core before the clamping assembly clamps the stator core and the twisting assembly bends the copper wires. The stator core is provided with multiple layers of copper wires along the radial direction, and the copper wires extending along the same radial direction form a group. The sliding assembly can extend into the space between two adjacent groups of copper wires. The sliding assembly can separate the two adjacent groups of copper wires, so that the two groups of copper wires will not be mixed during the bending process, and the orderliness of the copper wires on the stator core is improved.

[0008] The number of sliding assemblies is multiple, and each sliding assembly extends into the space between two adjacent groups of copper wires. Multiple sliding assemblies can be arranged at the same height. The position at which the sliding assembly abuts against the copper wire is taken as a reference point. In this way, the multiple sliding assemblies can ensure that the starting bending positions of the copper wires at different positions are consistent, the twisting consistency of the multiple copper wires is ensured, the twisting orderliness of the multiple copper wires is improved, and the processing precision is improved.

[0009] The slot paper is arranged in the slot hole of the stator core and serves as an insulator. Part of the slot paper extends out of the slot hole of the stator core. The sliding assembly can extend into the space between two adjacent slot papers, and the sliding assembly can abut against part of the slot paper extending out of the stator core. During the bending process of the copper wire, the abutting action of the sliding assembly on the slot paper can prevent the slot paper from being dragged by the copper wire during the bending of the copper wire, prevent the slot paper from being damaged due to accumulation in the slot hole, protect the slot paper during the bending of the copper wire, reduce the damage rate of the slot paper, and improve the reliability during the bending of the copper wire.

DETAILED DESCRIPTION

[0044] In order to enable a more complete understanding of the above-mentioned objects, features and advantages of the present application, the present application will be described in further detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0045] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application, but the present application can also be implemented in other manners different from those described herein, and therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0046] The following refers to Figures 1 to 12 The torsion forming mechanism according to some embodiments of the present application is described.

[0047] In combination with Figure 1 , Figure 2 and Figure 4 , in some embodiments of the present application, a torsion forming mechanism is provided for twisting copper wires assembled on a stator core, the torsion forming mechanism comprising: a base assembly 100, a clamping assembly 200, a radial movement assembly 300 and a torsion assembly 400. The clamping assembly 200 is arranged on the base assembly 100, and the clamping assembly 200 is used for clamping the stator core. The radial movement assembly 300 is arranged on the base assembly 100, and the radial movement assembly 300 comprises a plurality of sliding assemblies 320, which can move along the radial direction of the stator core to extend between two groups of copper wires distributed in the circumferential direction and between two adjacent groups of slot papers. The torsion assembly 400 is arranged on the base assembly 100, and the torsion assembly 400 is used for bending the copper wires.

[0048] The torsion forming mechanism is used for twisting copper wires on a stator core to a preset angle. The torsion forming mechanism is composed of a base assembly 100, a clamping assembly 200 and a radial motion assembly 300. The base assembly 100 bears the clamping assembly 200 and the radial motion assembly 300. The clamping assembly 200 and the radial motion assembly 300 are installed on the same bearing part, so that the relative position of the clamping assembly 200 and the radial motion assembly 300 will not change, thereby improving the stability of the twisting process. The clamping assembly 200 can clamp the stator core to prevent the stator core from shaking. The twisting assembly 400 can twist the copper wires and automatically complete the bending process of the copper wires.

[0049] Specifically, when the copper wires need to be twisted, the stator core assembled with the copper wires can be transferred to the clamping assembly 200 by a tool, for example, the stator core assembled with the copper wires is transferred to the clamping station of the clamping assembly 200 by a mechanical hand, and the clamping assembly 200 can clamp the stator core. During the bending process of the copper wires, the copper wires will be subjected to a pulling force, so that the stator core is subjected to an axial pulling force. In order to improve the stability of the copper wire bending process, the stator core is clamped by the clamping assembly 200, so that the position of the stator core is not easy to change, and therefore the position of the copper wire on the stator core is not easy to change, ensuring that the twisting assembly 400 can stably bend the copper wire.

[0050] The sliding assembly 320 in the radial motion assembly 300 can move radially along the stator core. When the clamping assembly 200 clamps the stator core and before the twisting assembly 400 bends the copper wire, the sliding assembly 320 can move radially along the stator core and extend between the two groups of copper wires distributed in the circumferential direction of the stator core. The stator core has multiple layers of copper wires distributed in the radial direction, wherein multiple copper wires extending in the same radial direction form a group, and the sliding assembly 320 can extend between adjacent two groups of copper wires. The sliding assembly 320 can space the adjacent two groups of copper wires to prevent the adjacent two groups of copper wires from being disordered during the bending process, which is beneficial to improve the neatness of the copper wires on the stator core.

[0051] The number of sliding assemblies 320 is multiple, and each sliding assembly 320 extends between adjacent two groups of copper wires. Multiple sliding assemblies 320 can be arranged at the same height, and the position at which the sliding assembly 320 abuts against the copper wire is taken as a reference point. This allows the multiple sliding assemblies 320 to ensure that the starting bending positions of the copper wires at different positions are consistent, ensuring the consistency of the twisting of the multiple copper wires, which is beneficial to improve the twisting neatness of the multiple copper wires and improve the processing precision.

[0052] The slot paper is arranged in the slot hole of the stator core, and the slot paper has an insulation effect. A part of the slot paper extends out of the slot hole of the stator core. The sliding assembly 320 can extend between two adjacent slot papers, and the sliding assembly 320 can abut against the part of the slot paper extending out of the stator core. During the bending of the copper wire, the abutting effect of the sliding assembly 320 on the slot paper can avoid the slot paper from being dragged by the copper wire due to the bending of the copper wire, and can avoid the problem of damage of the slot paper due to the accumulation of the slot paper in the slot hole. The slot paper is protected during the bending of the copper wire, the damage rate of the slot paper is reduced, and the reliability during the bending of the copper wire is improved.

[0053] In combination Figure 1 and Figure 3 As shown in FIGS. 1, 2, and 3, in one possible embodiment, the clamping assembly 200 includes a mounting plate 210, a first driving member 230, two clamping members 220, and a limiting assembly 240. The mounting plate 210 is connected to the base assembly 100, and the first driving member 230 is arranged on the mounting plate 210. The two clamping members 220 are connected to the first driving member 230, and the first driving member 230 is configured to drive the two clamping members 220 to move towards or away from each other. The limiting assembly 240 is arranged on the mounting plate 210, and a part of the limiting assembly 240 is configured to abut against a jig clamping the stator core to limit the movement of the jig along the axial direction.

[0054] In this embodiment, the mounting plate 210 is mounted on the base assembly 100. For example, the mounting plate 210 can be locked on the base assembly 100 by a locking member such as a screw. The first driving member 230 is mounted on the mounting plate 210, and the first driving member 230 can be locked on the mounting plate 210 by a locking member, so as to ensure the stable connection between the first driving member 230 and the mounting plate 210. During the clamping of the stator core by the clamping assembly 200, the clamping assembly 200 is prevented from sliding relative to the mounting plate 210, and the clamping stability of the clamping assembly 200 to the stator core is improved.

[0055] The two clamping members 220 are connected to the first driving member 230, and the first driving member 230 is configured to drive the two clamping members 220 to move towards or away from each other. When the stator core is inserted between the two clamping members 220, the first driving member 230 can drive the two clamping members 220 to move towards each other, so as to clamp the stator core by the two clamping members 220.

[0056] In one possible application, the outer surface of the stator core is a curved surface. Therefore, a clamping curved surface can be formed on the clamping member 220. When the clamping member 220 clamps the stator core, the clamping curved surface is fitted with the outer surface of the stator core, the adaptability of the clamping member 220 to the stator core is improved, and the clamping stability of the clamping assembly 200 to the stator core is further improved.

[0057] The limiting assembly 240 is further installed on the mounting plate 210, and when a part of the stator core passes between the two clamping members 220, the limiting assembly 240 can cooperate with the jig clamping the stator core, so that the limiting assembly 240 limits the jig.

[0058] Specifically, in the process of bending the copper wire by the twisting assembly 400, as the copper wire is bent, the copper wire will be subjected to an axial force from the twisting assembly 400, and the force received by the copper wire will act on the stator core. The jig clamps the stator core, so the stator core will act on the stator core. In order to avoid the stator core being pushed away from the clamping assembly 200, the jig is limited by the limiting assembly 240, so that the limiting assembly 240 limits the axial movement of the jig along the stator core, thereby limiting the axial movement of the stator core, which is beneficial to improve the stability during the bending of the copper wire and improve the bending quality of the copper wire.

[0059] In a possible application, the first driving member 230 can be a jaw cylinder, and the two clamping members 220 are respectively locked on two jaws of the jaw cylinder.

[0060] As shown in Figure 3 In a possible embodiment, the limiting assembly 240 includes a second driving member 241 and a pressing member 242. The second driving member 241 is arranged on the mounting plate 210, and the pressing member 242 is connected with the second driving member 241. The second driving member 241 is used to drive the pressing member 242 to move, and the pressing member 242 is used to abut against the jig.

[0061] In this embodiment, the second driving member 241 is installed on the mounting plate 210, for example, the second driving member 241 can be locked on the mounting plate 210 by screws or the like.

[0062] The pressing member 242 is connected with the second driving member 241, and the second driving member 241 can drive the pressing member 242 to move. When a part of the stator core passes between the two clamping members 220, the pressing member 242 can cooperate with the jig, so that the pressing member 242 limits the jig. The limiting assembly 240 limits the axial movement of the jig along the stator core, thereby limiting the axial movement of the stator core, which is beneficial to improve the stability during the bending of the copper wire and improve the bending quality of the copper wire.

[0063] In a possible application, the pressing member 242 is detachably connected to the second driving member 241. In the process of limiting the jig by the pressing member 242, the pressing member 242 may be damaged due to excessive force. When the pressing member 242 is damaged, the pressing member 242 can be detached from the second driving member 241 and replaced. Compared with the way of limiting the jig by the second driving member 241 directly, the way of limiting the jig by the pressing member 242 can reduce the damage rate of the second driving member 241 and save the maintenance cost of the equipment.

[0064] In addition, the pressing member 242 can be conveniently processed to form a structure matched with the jig, so as to improve the stability of the limiting assembly 240 in limiting the jig.

[0065] In a possible application, the second driving member 241 can be a driving cylinder.

[0066] For example, the pressing member 242 and the output shaft of the driving cylinder can be locked by screws, or one of the pressing member 242 and the output shaft of the driving cylinder is provided with external threads, and the other is provided with internal threads, so that the pressing member 242 and the output shaft of the driving cylinder are directly screwed.

[0067] As shown in Figure 3 In a possible embodiment, the limiting assembly 240 further includes a guide member 243, the guide member 243 is arranged on the mounting plate 210, and the guide member 243 is provided with a guide hole, and the pressing member 242 can slide in the guide hole.

[0068] In this embodiment, the guide member 243 is mounted on the mounting plate 210. For example, the guide member 243 can be locked on the mounting plate 210 by screws or the like.

[0069] The guide hole is formed on the guide member 243 and extends along the radial direction of the stator core. The pressing member 242 passes through the guide hole and matches with the jig. The guide member 243 guides the pressing member 242, ensures that the pressing member 242 can stably move to the position matched with the jig, and is beneficial to improve the matching stability of the pressing member 242 and the jig.

[0070] In the case that the pressing piece 242 limits the jig, the axial force acting on the jig can cause the pressing piece 242 to be bent. In order to ensure that the pressing piece 242 can stably limit the jig, a part of the pressing piece 242 passes through the guide piece 243, and the guide piece 243 can protect the pressing piece 242. When the pressing piece 242 is subjected to an axial force, the axial force acting on the pressing piece 242 is dispersed on the guide piece 243 due to the large contact area between the guide piece 243 and the pressing piece 242, so that the bending of the pressing piece 242 can be effectively avoided. The pressing piece 242 cooperates with the guide piece 243, so that the pressing piece 242 can bear a larger axial force and stably limit the jig, which is beneficial to improve the stability in the copper wire bending process.

[0071] In combination with Figure 1 , Figure 4 and Figure 5 , in a possible embodiment, the radial movement assembly 300 includes a first driving assembly 310 and a sliding assembly 320. The first driving assembly 310 is connected with the base assembly 100, and the first driving assembly 310 includes a guide groove 316 extending along the radial direction of the stator core. The sliding assembly 320 is assembled with the first driving assembly 310, and a part of the sliding assembly 320 is located in the guide groove 316. The first driving assembly 310 is used to drive the sliding assembly 320 to slide along the guide groove 316. The copper wires are in multiple groups, and the multiple groups of copper wires are distributed along the circumferential direction of the stator core. A part of the sliding assembly 320 is used to extend into the space between the adjacent two groups of copper wires and contact the slot paper.

[0072] In this embodiment, the first driving assembly 310 includes the guide groove 316 extending along the radial direction of the stator core, and a part of the sliding assembly 320 is located in the guide groove 316, so that the sliding assembly 320 can move along the radial direction of the stator core. The first driving assembly 310 can drive the sliding assembly 320 to slide along the guide groove 316, and the sliding assembly 320 can abut against the part of the slot paper extending out of the stator core. In the process of bending the copper wire, the abutting action of the sliding assembly 320 on the slot paper can avoid the slot paper being dragged by the copper wire due to the bending of the copper wire, avoid the problem that the slot paper is accumulated in the slot hole and damaged, protect the slot paper in the process of bending the copper wire, reduce the damage rate of the slot paper, and improve the reliability in the process of bending the copper wire.

[0073] The guide groove 316 guides the sliding assembly 320, so that the sliding assembly 320 can accurately extend into the space between the adjacent two groups of copper wires, avoid scratching the copper wire and the slot paper, prevent the copper wire from being abraded and the slot paper from being damaged, improve the product quality, and reduce the waste rate.

[0074] In combination Figure 1 、 Figure 4 and Figure 5 As shown in FIGS. 1, 2, 3, and 4, in one possible embodiment, the first driving assembly 310 includes a first rotating disc 311, a rotating body 312, a second rotating disc 313, and a third driving member 314. The rotating body 312 is arranged on the base assembly 100. The first rotating disc 311 is arranged concentrically with the rotating body 312 and rotates synchronously with the rotating body 312. The first rotating disc 311 is provided with a plurality of arc-shaped grooves 315 distributed along the circumferential direction of the first rotating disc 311. The second rotating disc 313 is connected to the base assembly 100 and arranged concentrically with the first rotating disc 311. The second rotating disc 313 is provided with a plurality of guide grooves 316 distributed along the circumferential direction of the second rotating disc 313. The third driving member 314 is arranged on the base assembly 100 and used to drive the second rotating disc 313 to rotate. The sliding assembly 320 is provided in multiple groups. Each group of the sliding assembly 320 is matched with one guide groove 316 and one arc-shaped groove 315. A part of the sliding assembly 320 extends into the arc-shaped groove 315 through the guide groove 316. In the case that the second rotating disc 313 rotates, the inner wall of the arc-shaped groove 315 pushes the sliding assembly 320 to move along the guide groove 316.

[0075] In this embodiment, the rotating body 312 is connected to the base assembly 100. The first rotating disc 311 can rotate synchronously with the rotating body 312. Exemplarily, the rotating body 312 can be a slewing bearing. The outer ring of the slewing bearing is locked with the base assembly 100 by screws or other locking members. The first rotating disc 311 is fixed with the inner ring of the slewing bearing, so that the first rotating disc 311 can rotate with the inner ring of the slewing bearing, which is beneficial to improve the rotation stability of the first rotating disc 311. The second rotating disc 313 is connected to the base assembly 100. The first rotating disc 311 and the second rotating disc 313 are arranged concentrically, so that the radial dimension of the second rotating disc 313 can be set to be greater than the radial dimension of the first rotating disc 311. Then, the circumferential edge of the second rotating disc 313 is locked to the base assembly 100 by screws or other locking members.

[0076] A plurality of arc-shaped grooves 315 are formed on the circumferential direction of the first rotating disc 311. A plurality of sliding grooves are formed on the circumferential direction of the second rotating disc 313. A part of the sliding assembly 320 can extend into the arc-shaped grooves 315 and the sliding grooves. The third driving assembly is installed on the mounting frame. The third driving member 314 can drive the first rotating disc 311 to rotate. In the process of rotating the first rotating disc 311, the inner wall of the arc-shaped groove 315 can push the sliding assembly 320, so that the sliding assembly 320 can slide along the sliding groove. The number of the sliding assembly 320 is multiple. The plurality of sliding assemblies 320 are located on the outer side of the copper wire group. A part of the sliding assembly 320 can extend into the adjacent two groups of copper wires distributed along the circumferential direction.

[0077] The sliding assembly 320, the first rotating disc 311 and the second rotating disc 313 cooperate with each other, so that the sliding assembly 320 can be smoothly pushed between two adjacent groups of copper wires, avoiding abrasion of the copper wires and damage to the paper.

[0078] Exemplarily, the third driving member 314 comprises a rotating motor 317, a first gear 318 and a second gear 319. The second gear 319 is integrally formed with the outer periphery of the first rotating disc 311. The rotating motor 317 can drive the first gear 318 to rotate, and the first gear 318 and the second gear 319 are in mesh with each other.

[0079] In combination with FIGS. 3, 4 and 5, Figure 4 Figure 5 and Figure 6 In a possible embodiment, the sliding assembly 320 comprises a roller 321, a sliding block 322 and a spacing assembly 323. The roller 321 extends into the arc-shaped groove 315. The sliding block 322 is connected with the roller 321 and is located in the guide groove 316. The spacing assembly 323 comprises two groups of spacing pieces 324, which are connected with the sliding block 322 and have an increasing distance in the radial direction of the first rotating disc 311 and away from the axis of the first rotating disc 311.

[0080] In this embodiment, the roller 321 extends into the arc-shaped groove 315. When the first rotating disc 311 rotates, the inner wall of the arc-shaped groove 315 can push the roller 321. The surface of the roller 321 is curved, so that the inner wall of the arc-shaped groove 315 can stably push the roller 321 by cooperation of the roller 321 and the arc-shaped groove 315. The sliding block 322 is connected with the roller 321 and is located in the guide groove 316. When the roller 321 is pushed, the sliding block 322 can slide along the guide groove 316, so that the sliding block 322 approaches or moves away from the axis of the first rotating disc 311. The guide groove 316 guides the sliding block 322, ensuring that the sliding block 322 can stably drive the spacing pieces 324 to move in the radial direction of the second rotating disc 313.

[0081] The two groups of spacing pieces 324 are connected with the sliding block 322 and have an included angle, and the distance between the two groups of spacing pieces 324 increases away from the axis of the second rotating disc 313. When the two groups of spacing pieces 324 extend between two adjacent groups of copper wires, the distance between the spacing pieces 324 at the head is small, so that the spacing pieces 324 can easily extend between the two adjacent groups of copper wires and are not prone to collide with the copper wires. As the two groups of spacing pieces 324 extend, the positions with a larger distance between the two groups of spacing pieces 324 can contact the two adjacent groups of copper wires. The two groups of spacing pieces 324 support the two adjacent groups of copper wires, avoiding the problem of copper wire shaking during the bending process, and further improving the stability during the transfer process.​

[0082] Moreover, since the separator 324 can support the copper wire, it can ensure that the starting bend of the copper wire is consistent at all points, and ensure the consistency of the twisting of multiple copper wires, which is conducive to improving the twisting uniformity of multiple copper wires and improving the processing accuracy.

[0083] Combination Figure 4 and Figure 6 As shown, in one possible embodiment, the separator 324 includes a first support rod 325, a second support rod 326, and a locking member. The first support rod 325 is connected to the slider 322, and the second support rod 326 is rotatably connected to the first support rod 325. The rotation axis of the second support rod 326 is aligned with the axis of the first turntable 311. The locking member is used to lock the first support rod 325 and the second support rod 326.

[0084] In this embodiment, when the first support rod 325 and the second support rod 326 are not locked together, the second support rod 326 can rotate relative to the first support rod 325. By rotating the second support rod 326, the included angle between the two second support rods 326 in the two sets of separators 324 can be adjusted.

[0085] When the separator 324 moves, the first end of the separator 324 extends into the space between two adjacent sets of copper wires.

[0086] When the included angle between the two second support rods 326 is large, the width of the first end of the separator 324 is also large, making it prone to interference with the copper wires. When the included angle between the two second support rods 326 is small, it is difficult for them to effectively support the two adjacent sets of copper wires. Therefore, the included angle between the two second support rods 326 can be adjusted by changing the rotational position of the second support rods 326 relative to the first support rod 325. This ensures that the separator 324 can be easily inserted between the two adjacent sets of copper wires while also providing effective support for them.

[0087] For example, a threaded hole is machined on the first support rod 325, and a mounting hole is machined on the second support rod 326. The locking member can be a locking bolt. After the locking bolt passes through the mounting hole, it engages with the threaded hole, thereby locking the second support rod 326 to the first support rod 325.

[0088] Combination Figure 4 and Figure 5As shown in the figure, in a possible embodiment, the sliding assembly 320 further comprises a plurality of third bearing rods 327 and a cover plate 328. The plurality of third bearing rods 327 are connected to the first rotating disc 311, and the plurality of third bearing rods 327 are distributed along the circumference of the first rotating disc 311, and a guide gap is formed between any two third bearing rods 327, and the first bearing rod 325 is located in the guide gap. The cover plate 328 is connected to the third bearing rod 327, and a part of the first bearing rod 325 is located between the cover plate 328 and the first rotating disc 311.

[0089] In this embodiment, a plurality of third bearing rods 327 are connected to the axial end surface of the second rotating disc 313, a guide gap is formed between any two adjacent bearing rods, and the guide gap extends along the radial direction of the second rotating disc 313. The first bearing rod 325 is located in the guide gap, and the first bearing rod 325 can slide in the guide gap, and the guide gap guides the first bearing rod 325, further ensuring that the sliding assembly 320 can stably move along the radial direction of the second rotating disc 313.

[0090] The cover plate 328 is connected to the third bearing rod 327, and the cover plate 328 can be connected to the third bearing rod 327 by screws or other locking members, so that the cover plate 328 is detachably connected to the third bearing rod 327. A part of the cover plate 328 covers the opening of the guide gap, so that the cover plate 328 covers a part of the first bearing rod 325, and the cover plate 328 limits the first bearing rod 325, avoiding the first bearing rod 325 from separating from the second rotating disc 313, and ensuring that the partition piece 324 can stably move along the second rotating disc 313.

[0091] The sliding assembly 320 can be disassembled by disassembling the cover plate 328, thereby facilitating the maintenance or replacement of the sliding assembly 320, and improving the maintenance convenience of the product.

[0092] In combination with Figure 1 , Figure 2 , Figure 7 , Figure 9 and Figure 10 , in a possible embodiment, the torsion assembly 400 comprises a plurality of rotating assemblies 410. The rotating assembly 410 comprises a torsion shaft 411 and a second driving assembly 412. A plurality of wire insertion grooves 4113 are arranged on the circumferential side wall of the torsion shaft 411, the wire insertion grooves 4113 are used for the copper wire to extend into, the base assembly 100 is provided with a first through hole, and the radial movement assembly 300 is provided with a second through hole, and the first through hole, the second through hole and the torsion shaft 411 are concentrically arranged. The second driving assembly 412 is connected to the base assembly 100, and the second driving assembly 412 is used for driving the torsion shaft 411 to rotate. The torsion shafts 411 in the plurality of rotating assemblies 410 are concentrically arranged.

[0093] In this embodiment, the circumferential side wall of the torsion shaft 411 is formed with a plurality of wire insertion grooves 4113 extending along the axial direction of the torsion shaft 411. The copper wires on the stator core are distributed along the circumferential direction of the stator core and are distributed in multiple layers. The copper wires in one layer can be inserted into the wire insertion grooves 4113 of one torsion shaft 411, and one copper wire is inserted into one wire insertion groove 4113.

[0094] The second driving assembly 412 can drive the torsion shaft 411 to rotate. Since a part of the copper wire is inserted into the wire insertion groove 4113, as the torsion shaft 411 rotates, the part of the copper wire that is not inserted into the wire insertion groove 4113 can be bent.

[0095] The torsion shafts 411 in the plurality of rotating assemblies 410 are coaxially arranged in a sleeved manner. The multiple layers of copper wires can be sequentially inserted into the wire insertion grooves 4113 of the coaxially arranged plurality of torsion shafts 411, and one layer of copper wires corresponds to one torsion shaft 411.

[0096] Since each rotating assembly 410 has an independent second driving assembly 412, each torsion shaft 411 can realize independent rotation function, so that the torsion angle of each layer of copper wire can be controlled, and the torsion angle of each layer of copper wire can be adjusted independently, which can improve the flexibility in the bending process of the copper wire. When the rotation angles of the plurality of torsion shafts 411 are the same, it can ensure that the torsion angles of the copper wires in different layers are the same, which is beneficial to improve the product quality.

[0097] In one possible application, the second driving assembly 412 includes a driving assembly 416, a driving gear 417, and a driven gear 418. The torsion shaft 411 includes a shaft body 4111 and a rotating bearing 4112. The shaft body 4111 is provided with the wire insertion groove 4113. The outer ring of the rotating bearing 4112 is connected with the base assembly 100, the inner ring of the rotating bearing 4112 is connected with the shaft body 4111, and the inner ring of the rotating bearing 4112 is also connected with the driven gear 418. The driving assembly 416 drives the driving gear 417 to rotate, the driving gear 417 drives the driven gear 418 to rotate, the driven gear 418 drives the inner ring of the rotating bearing 4112 to rotate, and in turn drives the shaft body 4111 to rotate.

[0098] The first through hole on the base assembly 100 and the second through hole on the radial movement assembly 300 can accommodate the copper wire. After the copper wire passes through the first through hole and the second through hole, it is inserted into the wire insertion groove 4113.

[0099] In combination with Figure 7 , Figure 8 and Figure 11As shown, in one possible embodiment, the rotating assembly 410 further comprises sliding wheels 413, which are arranged on the torsion shaft 411, and the number of the sliding wheels 413 is two, and the two sliding wheels 413 are located on the two sides of the radial direction of the torsion shaft 411. The torsion assembly 400 further comprises two groups of guide assemblies 430, which are connected with the base assembly 100, and the two groups of guide assemblies 430 are located on the two sides of the radial direction of the torsion shaft 411. The guide assembly 430 comprises a plurality of guide seats 431, which are arranged in the axial direction of the torsion shaft 411 in layers, and the guide seat 431 is provided with a guide inclined groove 432, which is arranged in the radial direction of the torsion shaft 411. The two sliding wheels 413 respectively extend into the guide inclined grooves 432 in the same layer of the two groups of guide assemblies 430, and the inclined directions of the two guide inclined grooves 432 in the same layer are opposite.

[0100] In this embodiment, the two sliding wheels 413 are mounted on the torsion shaft 411, and the two sliding wheels 413 can rotate the torsion shaft 411.

[0101] The two groups of guide assemblies 430 are arranged on the two sides of the radial direction of the torsion shaft 411, and the guide assembly 430 is composed of a plurality of guide seats 431. Each guide seat 431 is provided with a guide inclined groove 432, and one sliding wheel 413 connected with the torsion shaft 411 can extend into the guide inclined groove 432 of one guide seat 431, and the other sliding wheel 413 connected with the torsion shaft 411 can extend into the guide inclined groove 432 of the other guide seat 431. The two sliding wheels 413 respectively extend into the guide inclined grooves 432 in the same layer of the two groups of guide assemblies 430.

[0102] In the case of rotation of the torsion shaft 411, the sliding wheel 413 rotates with the torsion shaft 411, and the sliding wheel 413 also slides in the guide inclined groove 432. Since the guide inclined groove 432 is arranged in the radial direction of the torsion shaft 411, and the inclined directions of the two guide inclined grooves 432 in the same layer are opposite, when one sliding wheel 413 slides upward in the guide inclined groove 432, the other sliding wheel 413 also slides upward in the guide inclined surface. With the rotation of the torsion shaft 411, the two sliding wheels 413 can simultaneously rise or fall in the rotating process, so that the torsion shaft 411 also moves in the axial direction in the rotating process.

[0103] In the process of bending the copper wire by the torsion shaft 411, the torsion shaft 411 will pull the copper wire, and the bending part of the copper wire will rub against the torsion shaft 411. Therefore, when the torsion shaft 411 rotates, the torsion shaft 411 also moves in the axial direction, so that the copper wire in the wire insertion slot 4113 does not slide relative to the torsion shaft 411, thereby protecting the surface quality of the copper wire and improving the quality of the product.

[0104] Since the plurality of torsion shafts 411 are sleeved with each other, the sliding wheels 413 on different torsion shafts 411 can be extended into the guide chute 432 of different layers, which is beneficial to the independent bending of the copper wire by different torsion shafts 411.

[0105] As shown in Figure 11 In a possible embodiment, the guide assembly 430 further comprises a position detection member 433, which is arranged on the guide seat 431 and is used to detect the position of the sliding wheel 413 in the guide chute 432.

[0106] In this embodiment, the position detection member 433 can detect the position of the sliding wheel 413 in the guide chute 432 during the sliding of the sliding wheel 413 in the guide chute 432.

[0107] The bending angle of the copper wire can be controlled by the rotation angle of the motor output shaft. In order to avoid the problem of excessive twisting of the copper wire due to the failure of the driving component, the position detection member 433 is arranged in the guide seat 431.

[0108] The sliding wheel 413 rotates synchronously with the torsion shaft 411, so the rotation angle of the sliding wheel 413 is the same as that of the torsion shaft 411. The rotation angle of the sliding wheel 413 can be determined by detecting the position of the sliding wheel 413 by the position detection member 433, so as to obtain the rotation angle of the torsion shaft 411. If the sliding wheel 413 reaches the set position without stopping, the position detection member 433 can send an abnormal detection signal to the controller at this time, and the controller can execute a shutdown action or output a reminder signal according to the abnormal detection signal.

[0109] By detecting the position of the sliding wheel 413 by the position detection member 433, the copper wire can be prevented from being excessively twisted, the damage rate of the copper wire is reduced, and the quality of the product is improved.

[0110] As shown in Figure 11 In a possible embodiment, the guide assembly 430 further comprises a stop member 434, which is arranged on the guide seat 431 and is used to adjust the inclination angle of the guide chute 432.

[0111] In this embodiment, the stop member 434 can adjust the inclination angle of the guide chute 432, so as to adjust the distance that the torsion shaft 411 can move in the axial direction. When the inclination angle of the guide chute 432 is small, the distance that the torsion shaft 411 can rise is small. When the inclination angle of the guide chute 432 is large, the distance that the torsion shaft 411 can rise is large.

[0112] Exemplarily, the stopper 434 is a stop bolt, which is screwed with the end of the guide seat 431, and the inclination angle of the guide seat 431 can be adjusted by rotating the stop bolt 434.

[0113] In any of the above embodiments, the sliding wheel 413 can roll relative to the guide chute 432.

[0114] In this embodiment, the part of the sliding wheel 413 extending into the guide chute 432 can roll in the guide chute 432, which can reduce the friction between the sliding wheel 413 and the guide chute 432.

[0115] Specifically, the sliding wheel 413 comprises a fixed plate 414 and a wheel body 415, the fixed plate 414 is connected to the rotating body 312, and the wheel body 415 is rotationally connected to the fixed plate 414, and the rotation axis of the wheel body 415 extends along the radial direction of the torsion shaft 411. When the sliding wheel 413 rotates with the torsion shaft 411, the wheel body 415 can roll in the guide chute 432, so that the wheel body 415 and the inner wall of the guide chute 432 are in rolling friction, and the friction between the wheel body 415 and the inner wall of the guide chute 432 is small, which is conducive to improving the stability of the torsion shaft 411 when rotating.

[0116] In combination with the figures shown in Figure 1 , Figure 7 and Figure 12 , in the above embodiments, the base assembly 100 comprises a guide column 110 extending along the radial direction of the torsion shaft 411, a connecting plate 120 provided with a sliding hole, the guide column 110 penetrating through the sliding hole, and the rotating body 312 connected to the connecting plate 120.

[0117] In this embodiment, the rotating body 312 is mounted on the connecting plate 120, and when the torsion shaft 411 moves along the axial direction, the torsion shaft 411 can drive the connecting plate 120 to move. The guide column 110 penetrates through the sliding hole on the connecting plate 120, so that the guide column 110 can guide the connecting plate 120, ensuring that the connecting plate 120 can only move along the axial direction of the torsion shaft 411, which ensures that the torsion shaft 411 can stably move along the axial direction without deviation, which is conducive to improving the bending quality of the copper wire by the torsion shaft 411.

[0118] The base assembly 100 further comprises a bottom plate 140 and a top plate 130, and the two ends of the guide column 110 are connected to the bottom plate 140 and the top plate 130, respectively. The top plate 130 is provided with a first through hole. The clamping assembly 200 and the radial motion assembly 300 are mounted on the top plate 130, and the bottom plate 140 supports the torsion assembly 400.
