Description

A permanent magnet motor winding device

Technical Field

Background Art

A permanent magnet motor is a motor that uses permanent magnets to generate a magnetic field. It generates a constant magnetic field through built-in permanent magnets without the need for an external power supply, so its design is simpler and its structure is more compact. At the same time, since no energy is consumed to generate a magnetic field, permanent magnet motors usually have higher efficiency. Permanent magnet motors are widely used in industrial drives, transportation, household appliances, aerospace and other fields.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

Example 1

Please refer to Figures 1 and 2. The present invention is a permanent magnet motor winding device, including two groups of symmetrically arranged winding drums 5, and a plurality of groups of stoppers 501 are arranged at intervals on the walls of the two groups of winding drums 5, and a winding groove is formed between two adjacent groups of stoppers 501; in one implementation of the present embodiment, the winding drum 5 is configured as a cylindrical structure, and during winding, the stoppers 501 are provided for limiting, and the coil 502 can be wound in the winding groove to avoid deviation. At the same time, five groups of winding grooves are provided on the winding drum 5. After one turn of the coil 502 is wound, it can be wound on the winding groove on the adjacent side, which is more efficient.

It should be noted that a stator 8 is provided inside the permanent magnet motor, and a plurality of groups of winding teeth 801 are fixedly arranged in a circumferential array inside the stator 8 , and the wound coil 502 can be sleeved on the winding teeth 801 .

It also includes an adjustment module and a rotation module, and the adjustment module is used to adjust the distance between the two groups of winding drums 5; specifically, for different types of permanent magnet motors, the required diameters of the winding coils 502 are different. In this embodiment, the adjustment module can adjust the distance between the two groups of winding drums 5, thereby adjusting the diameter of the wound coils 502;

The rotating module is used to drive the winding drums 5 on both sides to rotate so as to wind the copper wire into coils 502; it can be explained that during the winding process, the copper wire is first wound manually in the winding groove for one circle, and then the winding drums 5 on both sides are driven to rotate by the rotating module. When the winding drums 5 rotate, the copper wire can be wound into coils 502. Based on the number of turns selected for the coils 502, the rotating module can rotate the corresponding number of turns. After one group of coils 502 is wound, the shearing mechanism is used to cut the copper wire to carry out the winding of the next group of coils 502. After all the windings are completed, each coil 502 is removed. This embodiment can adjust the winding diameter of the coil 502 based on different models of permanent magnet motors, has a wider range of applications, and is easy to operate.

Example 2

On the basis of Example 1, please refer to Figures 4, 6 and 7-9. Several groups of grooves 503 are correspondingly opened on the wall of the winding drum 5, and each stopper 501 is slidably embedded in the groove 503, wherein each stopper 501 is connected to a pushing portion that drives it away from or close to the axial direction of the winding drum 5; it can be explained that before winding the coil 502, each stopper 501 is driven by the pushing portion to move in a direction away from the axial center, so that each stopper 501 extends out of the groove 503 and forms a winding groove to limit the coil 502, and separates the coils 502 in each winding groove. After the winding is completed, the pushing portion drives each stopper 501 to be re-embedded in the groove 503, and the top of the stopper 501 is flush with the notch, so that the staff can remove the wound coil 502 from the winding drum 5;

In this embodiment, please refer to Figure 5, the pushing part includes a circular groove 504 opened at the axis of the winding drum 5, a support shaft 7 is slidably arranged at the axis of the circular groove 504, and a plurality of groups of tapered grooves 701 are arranged at intervals on the shaft body of the support shaft 7, wherein each stopper 501 is fixed to a push rod 507 slidably arranged between the groove walls of the groove 503, and the other end of the push rod 507 extends into the circular groove 504 and rotatably arranges a roller 509, and a first spring 508 is provided on the push rod 507; specifically, one end of the first spring 508 is fixed to the stopper 501, and the other end is fixed to the groove wall of the groove 503; it can be said that It is clear that in the initial state, each roller 509 abuts against the bottom of the tapered groove 701, and the stopper 501 is embedded in the groove 503. When the coil 502 needs to be wound, the support shaft 7 is pulled along the axial direction to move, and the roller 509 can move along the inclined guide surface 702 of the tapered groove 701 toward the direction away from the axial center. The roller 509 synchronously pushes the stopper 501 to slide in the groove 503 through the push rod 507. At this time, the first spring 508 is in a stretched state. When the winding is completed, the support shaft 7 is pushed to return to its original position, and the first spring 508 synchronously drives the push rod 507 and the stopper 501 to return to their original position.

Further, please refer to Figure 4, two groups of winding drums 5 are arranged on one side of the positioning frame 402, and the pushing part also includes a positioning seat 6 fixedly arranged at the end of the winding drum 5, and a circular hole 601 is provided on the positioning seat 6. A push shaft 408 fixed to the support shaft 7 is slidably embedded in the circular hole 601. The push shaft 408 is slidably arranged between the positioning plates 407. A second spring 409 is provided on the push shaft 408. One end of the second spring 409 is fixed to the positioning plate 407, and the other end is fixed to the end of the support shaft 7. A bottom plate 401 is also fixedly arranged on one side of the positioning frame 402, and a bottom plate 401 is fixed on the bottom plate 401. A first cylinder 403 is arranged, and a driving end of the first cylinder 403 is fixed to a pushing frame 404, wherein two sets of push shafts 408 are in contact with the pushing frame 404; it can be explained that when adjusting the position of the support shaft 7, the first cylinder 403 is started to drive the pushing frame 404 to move, and during the movement, the pushing frame 404 can drive the support shaft 7 to move in a direction away from the positioning frame 402 through the push shaft 408. At this time, the second spring 409 is stretched to generate elastic force. When the first cylinder 403 is reset, the second spring 409 can synchronously drive the push shaft 408 and the support shaft 7 to reset.

In this embodiment, please refer to Figures 2 and 4. The adjustment module includes a screw 405 rotatably arranged on the side of the positioning frame 402 facing the winding drum 5. The threads on both sides of the screw 405 are rotated in opposite directions. The screw 405 is symmetrically spirally sleeved with a nut 406, and the nut 406 is fixed to the positioning seat 6, wherein the positioning plate 407 is synchronously fixed to the nut 406; it can be explained that when winding coils 502 of different diameters, the screw 405 is rotated, and the nut 406 can synchronously drive the positioning seat 6 and the winding drum 5 to move during the movement of the screw 405 to adapt to different winding requirements;

In addition, please refer to Figure 6, a sliding groove 505 is opened on the groove wall of the circular groove 504, and the support shaft 7 is fixed with a sliding seat 506 slidably arranged in the sliding groove 505; specifically, the support shaft 7 is limited by setting the sliding groove 505 and the sliding seat 506 to improve the stability of the support shaft 7 during movement.

Please refer to Figure 4, the rotating module includes a driving motor 4 fixed to one side of the workbench 1, and the output end of the driving motor 4 is fixed to the positioning frame 402; specifically, when winding, the driving motor 4 is started, and the driving motor 4 can synchronously drive the positioning frame 402 to rotate, thereby driving the winding drums 5 on both sides to rotate.

As a further solution of this embodiment, please refer to Figures 2-3 and 8. A mounting frame 101 is also fixedly arranged on the workbench 1, and a rotating shaft 102 is rotatably arranged on one side of the mounting frame 101. The end of the rotating shaft 102 is fixed to a positioning rod 202, and a plurality of groups of strip holders 203 are fixedly arranged in a circumferential array on the positioning rod 202. A winding wheel 2 is also slidably sleeved on the positioning rod 202, and a positioning groove 207 is provided at the axial end of the winding wheel 2. A strip slot 208 corresponding to the strip holder 203 is correspondingly provided on the groove wall of the positioning groove 207. It can be explained that when winding, the winding wheel 2 is sleeved on the positioning rod 202. As the copper wire is output, the winding wheel 2 can synchronously drive the positioning rod 202 and the rotating shaft 102 to rotate through the strip slot 208 and the strip holder 203. When the copper wire on a group of winding wheels 2 is completely output, it can be directly disassembled and replaced. The winding wheel 2 of this embodiment is very convenient to disassemble and assemble.

In order to improve the stability of the copper wire during winding, so that the copper wire has a certain tension during winding, in this embodiment, please refer to Figure 5, a tensioning wheel 308 is also slidably sleeved on the positioning rod 202, and a positioning groove 207 and a bar-shaped card groove 208 are correspondingly provided at the axis of the tensioning wheel 308. A friction wheel 307 is rotatably arranged on the tensioning wheel 308, and the friction wheel 307 is rotatably arranged in the U-shaped frame 309, wherein a telescopic rod 305 is fixedly arranged on the U-shaped frame 309, and the other end of the telescopic rod 305 is slidably inserted into the cylinder 304, and a third spring 306 is arranged on the telescopic rod 305; specifically, one end of the third spring 306 The third spring 306 in this embodiment is in a contracted state, so that the third spring 306 has a certain elastic force, and the friction wheel 307 can be pressed against the tension wheel 308. Therefore, when winding, the tension wheel 308 can be driven to rotate synchronously with the rotation of the positioning rod 202. Under the friction force of the friction wheel 307, the rotation of the positioning rod 202 will be subject to a certain resistance. The resistance can make the copper wire have a certain tension when it is output, so as to avoid the phenomenon of loose copper wire, and the coil 502 can be wound more neatly.

Furthermore, please refer to Figure 2, annular baffles 201 are symmetrically fixed on both sides of the winding wheel 2, and the annular baffles 201 on both sides and the winding wheel 2 form an annular groove for winding copper wire, an L-shaped bracket 103 is slidably arranged on the rotating shaft 102, and a limiting rod 301 is slidably arranged at the end of the L-shaped bracket 103, and the limiting rod 301 is rotated toward one end of the workbench 1 to be provided with a pressure wheel 3 for embedding in the annular groove, and the other end of the limiting rod 301 is fixed to the cylinder 304 through a connecting frame 303, and a through hole 104 is also provided between the L-shaped brackets 103, and the cylinder 304 is penetrated in the through hole 104, wherein a fourth spring 302 is also provided on the limiting rod 301, specifically, the fourth spring One end of the spring 302 is fixed to the L-shaped bracket 103, and the other end is fixed to the end of the limiting rod 301; it can be explained that when the winding wheel 2 is sleeved on the positioning rod 202, the pressure wheel 3 is embedded in the annular groove, and the fourth spring 302 is in a contracted state and pushes the pressure wheel 3 to contact the copper wire wound on the surface of the winding wheel 2. As the copper wire is output, the coil diameter of the copper wire on the winding wheel 2 decreases, and the fourth spring 302 always pushes the pressure wheel 3 to contact the copper wire. The limiting rod 301 synchronously drives the cylinder 304 to move toward the workbench 1 through the connecting frame 303. At this time, the elastic force of the third spring 306 is further increased, so that the friction between the friction wheel 307 and the tensioning wheel 308 is increased;

It should also be noted that as the copper wire is gradually output from the winding wheel 2, the overall mass of the winding wheel 2 decreases and the tension on the copper wire decreases. Therefore, this embodiment increases the friction between the friction wheel 307 and the tension wheel 308 to keep the tension on the copper wire constant and avoid the phenomenon of coil 502 being wound loose.

In order to wind the coil 502 in each winding groove, in this embodiment, please refer to Figures 2-3, a U-shaped holder 205 is slidably arranged on the workbench 1, and the annular baffles 201 on both sides of the winding wheel 2 are embedded in the U-shaped holder 205. A limit frame 204 is fixedly arranged on one side of the U-shaped holder 205, and the limit frame 204 is fixed to the driving end of the second cylinder 206 fixedly arranged on the workbench 1; specifically, when installing the winding wheel 2, the U-shaped holder 205 will be pushed out by the second cylinder 206 first, and the annular baffles 201 on both sides of the winding wheel 2 will be embedded in the U-shaped holder 205 and then sleeved on the positioning rod 2. When one turn of the coil 502 is wound, the U-shaped holder 205 is pushed to move on the workbench 1 by the second cylinder 206, and the U-shaped holder 205 synchronously drives the winding wheel 2 to move for position adjustment to correspond to the position of each winding groove.

In this embodiment, annular guide grooves 310 are provided on both sides of the tensioning wheel 308, and pin shafts 311 slidingly connected to the annular guide grooves 310 are symmetrically arranged at both ends of the U-shaped frame 309; specifically, when the winding wheel 2 is driven to move, the tensioning wheel 308 can be synchronously driven to move under the limiting action of the annular guide grooves 310 and the pin shafts 311.

In addition, a wire wheel 209 is arranged on one side of the limiting frame 204; specifically, the copper wire output from the winding wheel 2 first passes through the wire wheel 209 and then is wound on the winding drum 5, thereby improving the winding quality.

A winding method for a permanent magnet motor winding device comprises the following steps:

The second cylinder 206 pushes out the U-shaped holder 205, and the annular baffles 201 on both sides of the winding wheel 2 are inserted into the U-shaped holder 205 and then sleeved on the positioning rod 202;

The pusher drives each stopper 501 to move in a direction away from the axis, so that each stopper 501 extends out of the groove 503 and forms a winding groove;

The copper wire is manually wound in the winding groove for one circle, and the driving motor 4 is started. The driving motor 4 can synchronously drive the positioning frame 402 to rotate, thereby driving the winding drums 5 on both sides to rotate;

After the winding of one set of coils 502 is completed, the copper wire is cut by a shearing mechanism to start the winding of the next set of coils 502;

The second cylinder 206 pushes the U-shaped holder 205 to move on the workbench 1, and the U-shaped holder 205 simultaneously drives the winding wheel 2 to move to adjust the position to correspond to the position of each winding groove;

After all the winding is completed, the pusher drives each stopper 501 to be re-embedded into the groove 503, and the top of the stopper 501 is flush with the notch, and the staff removes the wound coil 502 from the winding drum 5.
