Description

Technical Field

[0001] This invention relates to the field of iron core winding technology, specifically to an equipment and method for winding the iron core of an automotive generator. Background Technology

[0002] The generator core is the core component of the generator's magnetic circuit. The performance of the core determines the generator's energy conversion efficiency, loss control, and operational stability. Core winding is one of the key processes in core manufacturing, offering significant advantages over traditional lamination processes. The core winding method, through continuous winding, greatly improves material utilization and reduces costs; it also enhances structural strength and rigidity and is suitable for high-performance thin strip materials that are difficult to stamp.

[0003] Patent document CN111113052B discloses a stator core winding device, comprising: a frame, on which a mounting base plate, a base, a guide frame, a forming device, a side pressure wheel, and a shearing device are mounted; the base has a first base cavity and a second base cavity; the mounting base plate has a first through-shaft hole aligned with the first base cavity, and a second through-shaft hole aligned with the second base cavity; a main shaft is inserted into the second base cavity, with its lower end passing through the second through-shaft hole, and a main shaft drive device is installed on the section of the main shaft protruding from the second through-shaft hole; the main shaft is connected and fixed to a needle plate by screws; the needle plate has a drive pin, a return spring, a needle plate locking plate, and a needle plate groove; the return spring is sleeved on the drive pin; a locking plate screw passes through the needle plate locking plate; and the drive pin is fixed in the needle plate groove by the locking plate screw and the needle plate locking plate.

[0004] Under the combined action of the driving pin tension, the friction between the side pressure wheel and the main shaft core, and the forming groove, the straight strip material is plasticized and shaped; after the straight strip material is formed, the driving pin continues to rotate in a circle, and when the set number of revolutions is reached, the first cylinder pushes the shear device to cut off the spiral strip material, and the strip forming process ends.

[0005] In practical applications, a needle plate is usually installed on the main shaft, and the needle plate has multiple drive pins. The drive pins are inserted into the toothed grooves of the strip, and the strip rotates through the drive pins when the main shaft rotates. The number, position and distance between the drive pins on the main shaft are fixed values. If the number of iron core grooves and the groove depth of the iron core change, the drive pins on the main shaft need to be removed and replaced, which is time-consuming and labor-intensive. In addition, various needle plates of different specifications need to be prepared to cope with various working conditions. When replacing a new needle plate, repositioning is required, which makes the operation cumbersome and affects work efficiency. Summary of the Invention

[0006] This invention provides a winding processing equipment and method for automotive generator cores, aiming to solve the problem in related technologies that, under conditions with different numbers and depths of core slots, it is necessary to disassemble the old pin assemblies and replace them with new ones, and reposition them, which is cumbersome and affects processing efficiency.

[0007] The present invention provides an automotive generator core winding processing equipment, including a frame, a guide assembly, a pin assembly and an adjustment assembly. The pin assembly includes a connecting plate and a plurality of pins. The pins are movably mounted on the connecting plate. The pin assembly cooperates with the guide assembly to insert the pins into the tooth grooves of the strip and drive the strip to wind to a preset specification. The adjustment assembly includes a quantity adjustment component, a position adjustment component, and a distance adjustment component. The quantity adjustment component is connected to some of the pins to drive some of the pins to move axially along the first connecting plate, thereby controlling the number of pins in normal operation. The position adjustment component is connected to the pins to drive the pins to move radially along the first connecting plate, thereby changing the position of the pins. The distance adjustment assembly is connected to some of the pins to drive some of the pins to rotate circumferentially along the first connecting plate, thereby controlling the distance between the pins in normal operation.

[0008] Preferably, the guiding assembly includes a guide block one, a guide element one, a guide element two, and a mandrel. The mandrel is coaxially arranged with the connecting disc. The guide block one has a spirally extending guide groove one to limit the pitch of the material strip when it passes through the guide groove. The guide element one and the guide element two are arranged around the mandrel to generate a thrust on the material strip in the direction of the mandrel, so as to wind the material strip along the tangent of the mandrel onto the mandrel. The diameter of the mandrel is smaller than the inner diameter of the iron core to be wound.

[0009] Preferably, the pin assembly further includes a connecting plate II, a connecting cylinder, and several connecting rods. The connecting plate II is coaxially and fixedly connected to the connecting plate via the connecting cylinder. The several connecting rods are evenly distributed along the circumference of the connecting plate II, and each connecting rod corresponds to a pin. An elastic element I is provided between the connecting rod and the pin to keep them apart. The pin slides within the connecting rod. A guide groove II is provided on the connecting plate II, and the pin slides within the guide groove II. The position adjustment element and the distance adjustment element are indirectly connected to the pin via the connecting rods.

[0010] Preferably, a relief groove is provided on the guide block 1, which is connected to the guide groove 2. When the pin passes through the guide block 1, it abuts against the guide block 1 and is pressed back into a contracted state. When the pin moves to the relief groove 1, the pin extends into the guide block 1 and is inserted between the toothed grooves carrying the material.

[0011] Preferably, the quantity adjustment component includes an adjustment component three fixedly connected to the connecting plate two, adjustment components one and two slidably disposed on the connecting cylinder, and cylinders one and two controlling the movement of adjustment components one and two. Adjustment components one, two and three each include a connecting ring and several limiting rods. The limiting rods are evenly distributed around the connecting ring, and each limiting rod corresponds to a pin. A baffle is fixedly disposed on the pin. When cylinders one and two drive adjustment components one and two to move, the limiting rod abuts against the baffle, causing the pin to move along the axial direction of the connecting cylinder.

[0012] Preferably, the position adjustment component includes a limiting block 2 that moves along the axial direction of the connecting plate 2, a guide block 2, and a cylinder 3 that controls the movement of the limiting block 2. A radially extending guide groove 4 is provided on the connecting plate 2, and the connecting rod slides in the guide groove 4. A guide block 2 is provided at the end of the connecting rod away from the pin. The surfaces of the limiting block 2 and the guide block 2 that are close to each other are set as mutually compatible inclined surfaces. The inclined surfaces of the limiting block 2 and the guide block 2 are in constant contact, so that when the limiting block 2 moves, the connecting rod is driven to move in the guide groove 4 through the guide block 2.

[0013] Preferably, the distance adjustment component includes a gear ring 1, a gear ring 2, and a motor 4. The motor 4 is mounted on the connecting plate 2 and drives the gear ring 1 and gear ring 2 to rotate in opposite directions via a gear set. A plurality of limit blocks 1 are evenly arranged on the inner circumferential side of the gear ring 1 and gear ring 2. The limit blocks 1 have grooves that match the connecting rod. A guide groove 5 communicating with the guide groove 4 is opened on one side of a portion of the guide groove 4. The limit blocks 1 are located at the connection between the guide groove 4 and the guide groove 5, so that when a portion of the connecting rod enters the limit blocks 1, the motor 4 moves the connecting rod from the guide groove 4 to the guide groove 5 through the gear ring 1 and gear ring 2.

[0014] Preferably, the guide groove four is evenly distributed in the circumferential direction on the connecting plate two, and the guide groove five and part of the guide groove four are combined and evenly distributed in the circumferential direction on the connecting plate two.

[0015] Preferably, a cutting component is provided on the frame, the cutting component is located above the mandrel, the strip is wound through the cutting component, a guide plate is provided on the frame, the guide plate is located outside the mandrel and in front of the cutting component, the guide plate is in contact with the guide block, so that the strip that has passed through the cutting component continues to be wound on the side of the guide plate away from the cutting component.

[0016] A method for winding generator cores, using the aforementioned automotive generator core winding processing equipment.

[0017] Beneficial effects

[0018] 1. When the specifications of the processed iron core change, i.e. the number of slots of the iron core changes, the number of iron cores needs to be adjusted accordingly. By controlling the connection rods of different numbers and positions in the quantity adjustment component to abut against the baffle on the pin, the corresponding number of pins are driven to extend and retract on the connecting plate one, controlling the number of pins in the working state, and the pins in the working state are evenly distributed in the circumference of the connecting plate one to adapt to the number of slots of the processed iron core. 2. When the specifications of the processed iron core change, i.e. the groove depth of the iron core changes, the radial position of the pin on the connecting plate one needs to be adjusted accordingly. Several guide grooves four are opened radially on the connecting plate two. By using a guide block with an inclined surface on the connecting rod, and a limiting block two that is adapted to the guide block and always abuts against the guide block, the movement of the limiting block two drives the connecting rod to move in the guide groove four to change the radial position of the pin on the connecting plate one, so as to adapt to the groove depth of the processed iron core. 3. When the specifications of the processed iron core change, i.e., the number of pins in the working state changes, resulting in different distances between adjacent pins in the working state, the present invention provides several guide grooves five extending radially on the connecting plate two and communicating with the guide groove four. Through the cooperation of the distance adjustment component and the position adjustment, the corresponding number and position of connecting rods are moved into the limiting block one on the gear ring one and gear ring two. The motor four drives the gear ring one and gear ring two to rotate, moving some of the connecting rods from the guide groove four into the guide groove five. This makes the connecting rods in the guide groove five and the connecting rods corresponding to the pins in the working state evenly distributed in the circumferential direction of the connecting rods, so that the number and spacing of the pins in the working state are adapted to the specifications of the processed iron core.

[0019] 4. In this invention, when the specifications of the processed iron core change, the core parameters of the pin can be flexibly adjusted according to the specifications of the processed iron core through the cooperation of the quantity adjustment component, the position adjustment component and the distance adjustment component, without disassembling the pin assembly. This reduces downtime and adjustment time, and eliminates the need for secondary positioning after parameter adjustment, reducing tedious operations for workers and avoiding processing errors caused by positioning errors after pin type change.

[0020] 5. In this invention, the strip needs to be wound multiple times on the mandrel, and the thickness of the strip is relatively small, which will result in the strips wound on the mandrel being close together. When the strip is cut by the cutting component, multiple pieces of strip may be cut at the same time, affecting the processing quality. By using a guide plate to guide the strip that has passed through the cutting component to a position away from the cutting component, it is ensured that the cutting component will only cut one piece of strip when cutting, thus improving the processing quality.

[0046] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0047] Reference Figures 1 to 20 This invention discloses an automotive generator core winding processing equipment, comprising a frame 0, on which a guide assembly 1, a pin assembly 2, a cutting assembly 3, and an adjusting assembly 4 are mounted. The pin assembly 2 includes a connecting disc 23 and a plurality of pins 21. The pins 21 are evenly distributed circumferentially on the connecting disc 23 and can extend and retract axially along the connecting disc 23. The pins 21 extending from the connecting disc 23 are the effectively working pins 21. The guide assembly 1 and the pin assembly 2 cooperate to insert the pins 21 into the toothed grooves of the strip, driving the strip to wind to a preset specification. The cutting assembly 3 cuts the wound strip. The adjusting assembly 4 includes a quantity adjusting component 5, a distance adjusting component 6, and a position adjusting component 7, to adjust the number of pins 21 in the working state, the distance between pins 21, and the position of pins 21 according to changes in the number of core slots and the depth of the toothed grooves.

[0048] During operation, the strip is fed into the guide assembly 1 by an external conveying component. Then, the pin 21 engages with the toothed groove on the strip to drive the strip to move. At the same time, the guide assembly 1 limits the direction of movement of the strip. After the strip is wound, the cutting assembly 3 cuts the strip to cut it off and proceed with the winding of the next iron core.

[0049] When it is necessary to adjust the number of working pins 21, connect the quantity adjustment component 4 to a portion of the pins 21 to extend or retract some of the pins 21 from the connecting plate 23, thereby controlling the number of working pins 21. When it is necessary to adjust the distance between the working pins 21, connect the distance adjustment component 4 to a portion of the pins 21 to rotate some of the pins 21 on the connecting plate 23 by a certain angle, thereby controlling the working pins 21 to be evenly distributed on the connecting plate 23. When it is necessary to adjust the position of the working pins 21, connect the position adjustment component 4 to the pins 21 to move the pins 21 radially along the connecting plate 23, thereby adjusting the position of the working pins 21 on the connecting plate 23.

[0050] Reference Figures 1 to 9A mounting plate 01 extending upwards is fixedly mounted on the frame 0. A pin assembly 2 is mounted on the mounting plate 01. The pin assembly 2 includes a pin 21, a connecting rod 22, a first connecting plate 23, a second connecting plate 24, a connecting cylinder 25, and a first motor 26. A through hole is provided on the mounting plate 01. The first connecting plate 23 and the second connecting plate 24 are rotatably mounted in the through hole of the mounting plate 01. The two ends of the connecting cylinder 25 are fixedly connected to the first connecting plate 23 and the second connecting plate 24, respectively. That is, the first connecting plate 23 and the second connecting plate 24 are located on both sides of the connecting cylinder 25, and the first connecting plate 23 is located in front of the second connecting plate 24. The first motor 26 is fixedly mounted on the mounting plate 01. A drive shaft 241 is fixedly mounted on the end of the second connecting plate 24 away from the first connecting plate 23. The output end of the first motor 26 is connected to the drive shaft 241 through a drive belt so as to drive the second connecting plate 24 to rotate through the drive shaft 241. The connecting rod 22 is mounted on the connecting disc 24, and a groove adapted to the pin 21 is provided inside the connecting rod 22. The pin 21 slides inside the connecting rod 22. An elastic element 27 is provided between the pin 21 and the connecting rod 22. In this embodiment, there are multiple pins 21, connecting rods 22 and elastic elements 27, specifically 64. In this embodiment, the elastic element 27 is a compression spring. A guide groove 231 is provided on the connecting disc 23, which passes through the connecting disc 23. The pin 21 extends through the guide groove 231 to the front of the connecting disc 23, so that the pin 21 can be inserted between the teeth of the material strip, and the material strip is moved by the pin 21.

[0051] Reference Figures 1 to 3 The guide assembly 1 includes a guide block 11, a guide element 12, a guide element 23, and a mandrel 14. The guide block 11 is fixedly mounted on the mounting plate 01, the mandrel 14 is mounted on the connecting disc 23, and the guide elements 12 and 23 are mounted on the mounting plate 01. The guide block 11 is divided into a pre-bending section and a guiding section. The pre-bending section pre-bends the strip entering the guide assembly 1, and the guiding section causes the strip to wind along a specified pitch. The mandrel 14 is cylindrical and is located in the middle of the guide portion of the guide assembly 1. The mandrel 14 is adapted to the guide portion of the guide assembly 1. The first guide member 12 and the second guide member 13 are located on the outside of the mandrel 14 and are symmetrically arranged along the mandrel 14. They generate a pushing force on the strip in the direction of the mandrel 14 to wind the strip around the outer circle of the mandrel 14 tangentially. The movement direction of the strip is restricted from multiple directions by the first guide member 12, the second guide member 13, the guide block 11, and the mandrel 14 so that the strip is wound on the mandrel 14 according to a preset standard.

[0052] Reference Figure 7 and Figure 8The guide block 11 has a spiral guide groove 111 inside to limit the pitch of the strip winding. A pre-bending block 112 is fixedly installed in the guide groove of the pre-bending part of the guide block 11. The side of the pre-bending block 112 near the mandrel 14 is set as an arc with a gradually changing radius of curvature, and the radius of the arc of the pre-bending block 112 is larger than the radius of the strip to be wound, so as to perform a pre-, gradual and controllable bending of the strip, so as to avoid excessive local stress and strain inside the strip, which would lead to material tearing.

[0053] Reference Figure 3 , Figure 7 and Figure 8 The guide block 11 has a guide groove 113 on the side near the mounting plate 01. The guide groove 113 is set on the rotation trajectory of the pin 21. The side of the guide groove 113 near the connecting plate 23 is set as an inclined surface. When the pin assembly 2 drives the pin 21 to rotate, the pin 21 moves to abut against the inclined surface of the guide groove 113. Then, the pin 21 overcomes the elastic force of the elastic element and moves towards the connecting rod 22. That is, at the pre-bent part of the guide block 11, the pin 21 is in the retracted state. A clearance groove 114 is provided on the side of the guide block guide section near the mounting plate 01. The clearance groove 114 is connected to the guide groove 111. When the pin 21 moves to the clearance groove 114, the pin 21 moves away from the connecting rod 22 under the action of the elastic element. At this moment, the pin 21 is in the extended state. The extended pin 21 is inserted into the tooth groove of the material strip in the guide block 11 through the clearance groove 114 to drive the material strip to move and perform winding work around the mandrel 14.

[0054] Reference Figure 2 , Figure 3 , Figure 7 and Figure 8 An arc-shaped groove 115 is provided on the side away from the mandrel 14 between the pre-bent part of the guide block 11 and the guide part. The arc-shaped groove 115 is connected to the guide groove 111. The guide member 12 is set in the arc-shaped groove 115. When the strip enters the guide part from the pre-bent part of the guide block 11, the side of the strip away from the mandrel 14 will extend out of the guide groove 111 when the strip passes through the arc-shaped groove 115. The guide member 12 will generate pressure on the strip in the direction of the mandrel 14, so that the strip is wrapped around the mandrel 14 along the tangential side of the mandrel 14. At the same time, the position of the strip is limited, so that multiple pins 21 can be accurately inserted into the tooth groove of the strip. The second guide element 13 is positioned symmetrically to the first guide element 12 on the other side of the mandrel 14. It similarly restricts and corrects the position of the strip so that the strip is wound around the mandrel 14 along the tangential side. Multiple second guide elements 13 can be set around the mandrel 14 to improve the winding accuracy of the strip. In this embodiment, only one second guide element 13 is set.

[0055] Reference Figures 1 to 3The cutting component 3 is set on the mounting plate 01 above the mandrel 14. The wound strip continues to move to the cutting component 3 after passing through the guide 13. After the strip is wound, the cutting component 3 is triggered to cut the strip and remove the wound strip from the mandrel 14.

[0056] Reference Figure 4 In motor design, based on the three main objectives of optimizing motor electromagnetic performance, simplifying manufacturing processes, and controlling costs, the number of slots in the stator core is generally chosen to be a multiple of 16, such as 16, 32, 48, or 64 slots. In this embodiment, the number of pins 21 is set to 64, so that when a low number of slots is required for the core, some pins 21 can be retracted to handle various operating conditions.

[0057] The quantity adjustment component 5 is used to retract some unnecessary pins 21 when dealing with stator cores with different numbers of slots; the distance adjustment component 6 is used to adjust the distance between pins 21 when the number of stator core slots is 48; the position adjustment component 7 is used to adjust the radial position of pins 21 on the connecting plate 23 when the stator core slot depth changes. In this embodiment, the 64 pins 21 are divided into 16 groups, and the 16 groups of pins 21 are evenly distributed in the circumferential direction of the connecting plate 23. Each group of pins 21 is named pin 1 211, pin 2 212, pin 3 213, and pin 4 214, and pins 1 211, pin 2 212, pin 3 213, and pin 4 214 in each group are distributed sequentially in the circumferential direction of the connecting plate 23.

[0058] Similarly, since multiple connecting rods 22 correspond to multiple pins 211, the 64 connecting rods 22 are divided into 16 groups. The 16 groups of connecting rods 22 are evenly distributed around the circumference of the connecting plate 24. Each group of connecting rods 22 is named connecting rod 1 221, connecting rod 222, connecting rod 3 223, and connecting rod 4 224. The connecting rods 1 221, connecting rod 222, connecting rod 3 223, and connecting rod 4 224 in each group of connecting rods 22 are distributed sequentially around the circumference of the connecting plate 24. Pins 1 211, pin 2 212, pin 3 213, and pin 4 214 are respectively set to correspond to connecting rods 1 221, connecting rod 222, connecting rod 3 223, and connecting rod 4 224.

[0059] Reference Figures 10 to 6The quantity adjustment component 5 includes adjustment component one 51, adjustment component two 52 and adjustment component three 53. Adjustment component one 51 is fixedly mounted on the connecting cylinder 25. Adjustment component two 52 and adjustment component three 53 are slidably mounted on the connecting cylinder 25. Adjustment component one 51 corresponds to multiple pins one 211. Adjustment component two 52 corresponds to multiple pins two 212 and multiple pins four 214. Adjustment component three 53 corresponds to multiple pins three 213. Adjustment component three 53 is located between adjustment component one and adjustment component two 52. Adjustment component one 51 is located on the connecting cylinder 25 near the connecting plate two 24. Adjustment component two 52 is located on the connecting cylinder 25 near the connecting plate one 23.

[0060] Reference Figures 10 to 16 Adjusting component 1 51, adjusting component 2 52, and adjusting component 3 53 each include a connecting ring 54 and a limiting rod 55. The connecting ring 54 is sleeved on the connecting cylinder 25. Multiple limiting rods 55 are provided on the connecting ring 54, and all limiting rods 55 extend radially along the connecting ring 54. Multiple limiting rods 55 correspond to multiple pins 211. A through groove is provided on the limiting rod 55, extending radially along the connecting ring 54, and the through groove on the limiting rod 55 passes through the connecting rod 22 axially along the connecting ring 54. A baffle 28 is fixedly provided on the pin 21. The baffle 28 is located between the connecting rod 22 and the connecting disc 24. The baffle 28 is circular, and the diameter of the baffle 28 is larger than the width of the through groove on the limiting rod 55, that is, the baffle 28 cannot cross the limiting rod 55.

[0061] In this embodiment, the connecting ring 54 of the first adjusting member 51 is provided with 16 limiting rods 55, and the 16 limiting rods 55 are evenly distributed along the circumference of the connecting ring 54 in the first adjusting member 51; the connecting ring 54 of the second adjusting member 52 is provided with 32 limiting rods 55, the 32 limiting rods 55 are divided into 16 groups, with two closely spaced limiting rods 55 forming one group, and the 16 groups of limiting rods 55 are evenly distributed along the circumference of the ring in the second adjusting member 52; the connecting ring of the third adjusting member 53... Sixteen limiting rods 55 are provided on the 54, and the sixteen limiting rods 55 are evenly distributed in the circumferential direction of the connecting ring 54 of the third adjusting member 53. In this embodiment, the specifications of the limiting rods 55 on the second adjusting member 52 are different from those on the first adjusting member 51 and the third adjusting member 53, and they are all named limiting rods 55. The baffles 28 are also different in specifications for the different specifications of the limiting rods 55. In this embodiment, they are all named baffles 28 because they have the same function.

[0062] Reference Figures 10 to 16Multiple limiting rods 55 on adjusting components 1 51, 2 52, and 3 53 correspond one-to-one with multiple connecting rods 221, meaning the connecting rods 22 on adjusting components 1 51, 2 52, and 3 53 are staggered in the circumferential direction of the connecting cylinder 25. Cylinders 1 521 and 2 531 are fixedly installed on the side of connecting plate 2 24 away from connecting plate 1 23. A positioning rod 1 511 is fixedly installed on the connecting ring 54 of adjusting component 1 51 near the side of connecting plate 2 24. A positioning rod 2 522 is fixedly installed on the connecting ring 54 of adjusting component 2 52 near the side of connecting plate 2 24. A positioning rod 3 532 is fixedly installed on the connecting ring 54 of adjusting component 3 53 near the side of connecting plate 2 24. The positioning rods 1 511, 2 522, and 3 532 are staggered in the circumferential direction of the connecting cylinder 25. The components 5 are staggered circumferentially. Through holes adapted to the positioning rods 511, 522, and 532 are provided on the connecting ring 54 and the second connecting plate 24. Specifically, the positioning rod 522 passes through the through hole of the connecting ring 54 in the first adjusting component 51 and the third adjusting component 53, and also passes through the through hole on the second connecting plate 24, and is fixedly connected to the output end of the first cylinder 521; the positioning rod 532 passes through the through hole of the connecting ring 54 in the first adjusting component 51, and also passes through the through hole on the second connecting plate 24, and is fixedly connected to the output end of the second cylinder 531.

[0063] When the cylinder 521 drives the adjusting member 52 to move toward the connecting plate 24, the limiting rod 55 on the adjusting member 52 abuts against the baffle 28 on the pin 212 and pin 414, so as to drive the pin 212 and pin 414 to move away from the connecting plate 23, so as to retract the pin 212 and pin 414.

[0064] When the cylinder 2 531 drives the adjusting component 3 53 to move towards the connecting plate 2 24, the limiting rod 55 on the adjusting component 3 53 abuts against the baffle 28 on the pin 3 213, so as to drive the pin 3 213 to move away from the connecting plate 1 23, so as to retract the pin 3 213.

[0065] Reference Figure 4 , Figure 5 , Figure 17 and Figure 18The position adjusting component 7 includes a cylinder 3 71 and a limiting block 2 72. The cylinder 3 71 is fixedly mounted on the connecting plate 2 24, and the output end of the cylinder is fixedly connected to the limiting block 2 72. The limiting block 2 72 is slidably mounted on the transmission shaft 1 241. A guide groove 3 242 adapted to the connecting rod 22 is formed on the connecting plate 2 24. The guide groove 3 242 extends radially along the connecting plate 2 24, and multiple guide grooves 3 242 are formed. These multiple guide grooves 3 242 are evenly distributed around the circumference of the connecting plate 2 24, and each guide groove 3 242 corresponds to one of the multiple connecting rods 1 221. In this embodiment, the number of guide grooves is set to 64. The connecting rod 22 slides within the guide groove 3 242. Similarly, a guide groove 2 231 extends radially along the connecting plate 1 23, and the guide groove 231 is adapted to the pin 21. Each guide groove 231 corresponds to one of the multiple guide grooves 3 242. Two stops are provided on the connecting rod 22 along the extension direction of the connecting rod 22. The two stops are respectively located on both sides of the connecting plate 24 and abut against the connecting plate 24 to restrict the connecting rod 22 from moving axially relative to the connecting plate 24.

[0066] Reference Figure 4 , Figure 14 , Figure 17 and Figure 18 Limiting plates 73 are slidably arranged radially along the connecting cylinder 25 in the through grooves on limiting rods 551, 552, 553 and 554. Elastic element 2 75 is arranged between the through grooves on the quantity control assembly of limiting plate 73. Elastic element 2 75 causes the limiting plate 73 to move away from the axis of the connecting cylinder 25, thereby driving the pin 21 to move away from the axis of the connecting cylinder 25. A guide block 24 is fixedly provided at the end of the connecting rod 22 away from the connecting plate 23. The side of the guide block 24 away from the connecting plate 24 is set as an arc-shaped inclined surface. The inside of the limiting block 22 is adapted to the arc-shaped inclined surface on the guide block 24, that is, the arc-shaped inclined surface on the guide block 24 abuts against the inner wall of the limiting block 22. Under the action of the elastic element 25, the arc-shaped inclined surface of the guide block 2 is in constant contact with the inclined surface inside the limiting block 22. When the cylinder 3 71 controls the limiting block 22 to move towards the connecting plate 24, the limiting block 22 abuts against the guide block 24, thereby driving the connecting rod 22 to move in the guide groove 3 242 towards the axis of the connecting cylinder 25. This changes the radial position of the pin 21 on the connecting plate 23 through the connecting rod 22 to cope with the different depths of the stator core tooth groove. In this embodiment, the elastic element 25 is set in different specifications in different limiting rods 27, but according to its function, it is named elastic element 25.

The guide groove 232 extends radially along the connecting plate 23 and is adapted to the pin 21. In this embodiment, there are 32 guide grooves 232. The 32 guide grooves 232 and the 16 guide grooves 231 corresponding to the pin 211 are evenly distributed on the connecting plate 23 to cope with the situation where 48 pins 21 are evenly distributed on the connecting plate 23.

[0068] Reference Figures 10 to 11 A guide groove 243 is provided on the connecting plate 24 at the position corresponding to the guide groove 232. In this embodiment, there are 32 guide grooves 243. Multiple guide grooves 243 are provided in one-to-one correspondence with multiple guide grooves 232. The guide grooves 243 and the corresponding guide grooves 242 are connected at one end away from the axis of the connecting plate 24, so that the connecting rod 22 and the corresponding pin 21 can switch synchronously in the guide grooves 242 and 243.

[0069] Reference Figure 4 , Figure 12 , Figure 13 , Figure 17 and Figure 18The distance control component includes gear 61, gear 62, gear ring 63, gear ring 64, and motor 65. Gear 61 and gear 62 are rotatably mounted on connecting disk 24. Gear 61 and gear 62 are of the same specification and are externally meshed. On the side of connecting disk 24 away from connecting disk 23, annular grooves 244 and 245 are respectively formed to fit gear ring 63 and gear ring 64. Gear ring 63 is rotatably mounted in annular groove 244. An extension plate 641 is fixedly mounted on gear ring 64, and a connecting block (not shown in the figure) adapted to annular groove 245 is provided on extension plate 641 to allow gear ring 64 to be rotatably mounted on connecting disk 244. Gear ring 63 and gear ring 64 are arranged sequentially along the axial direction of connecting disk 244, with gear 61 meshing with gear ring 63 and gear 62 meshing with gear ring 64. Multiple limiting blocks 67 are provided inside both the first toothed ring 63 and the second toothed ring 64. The multiple limiting blocks 67 extend radially from the first connecting shaft 81 to the axis of the first connecting shaft 81. The multiple limiting blocks 67 are evenly distributed circumferentially along the first toothed ring 63 and the second toothed ring 64. In this embodiment, 16 limiting blocks 67 are provided inside both the first toothed ring 63 and the second toothed ring 64. The multiple limiting blocks 67 on the first toothed ring 63 are correspondingly arranged with the multiple connecting rods 222, and the multiple limiting blocks 67 on the second toothed ring 64 are correspondingly arranged with the multiple connecting rods 224.

The limiting block 67 is in the position where the guide groove 5 243 and the guide groove 3 242 are connected. The gear 61 is equipped with a transmission shaft 66. The output end of the motor 65 is connected to the transmission shaft through a transmission belt to drive the gear 61 to rotate. When the gear 61 rotates, it will drive the gear 62 to rotate synchronously. The gear 61 and the gear 62 drive the gear ring 63 and the gear ring 64 to rotate respectively. That is, the gear ring 63 and the gear ring 64 rotate synchronously in opposite directions.

[0071] When it is necessary to move connecting rod 222 and connecting rod 424 from guide groove 3242 to guide groove 5243, and simultaneously move pin 212 and pin 424 from guide groove 231 to guide groove 4232, cylinder 371 first drives guide block 11 away from connecting plate 224. Under the action of elastic element 275, multiple connecting rods 222 and multiple connecting rods 4 respectively move to the clearance groove 2 of limit block 167. At this time, motor 465 drives gear 262 to rotate through gear 161. Gear 161 and gear 262 respectively drive gear ring 163 and gear ring 264 to rotate synchronously in opposite directions, so that multiple connecting rods 222 and multiple connecting rods 424 can move to the corresponding guide groove 5243, and at the same time, the corresponding pin 212 and pin 424 can move to the corresponding guide groove 4232.

[0072] Reference Figure 21 In the first working condition, all pins 21 are in the second guide groove 231, all connecting rods 22 are in the third guide groove 242, and all 64 pins 21 are in working condition.

[0073] Reference Figure 22 In operating condition two, when the number of stator core slots is 48, the cylinder 2 531 drives the adjusting component 3 53 to move away from the connecting plate 1 23, so as to drive the pin 3 213 to move closer to the connecting plate 2 24. At this time, the pin 3 213 is out of working state. Then, the distance adjusting component 4 moves the pin 2 212 and the pin 4 214 from the guide groove 2 231 to the guide groove 4 232. At this time, the pin 1 211, pin 2 212 and pin 4 214 are evenly distributed on the connecting plate 1 23, and there are 48 pins 21 in working state at this time, which is for the operating condition with 48 stator core slots.

[0074] Reference Figure 23 In working condition three, when the number of stator core slots is 32, the cylinder three 71 drives the adjusting component two 52 to move away from the connecting plate one 23, so as to drive the pin two 212 and pin four 214 to move closer to the connecting plate two 24. That is, at this time only pin one 211 and pin three 213 are in working condition, that is, there are 32 pins 21 in working condition, and they are evenly distributed in the circumference of the connecting plate one 23, for the working condition of the number of stator core slots being 32.

[0075] Reference Figure 24Condition 4: When the number of stator core slots is 16, cylinders 521 and 531 drive adjusting parts 52 and 53 to move away from connecting plate 23, thereby driving pins 212, 213, and 214 to move closer to connecting plate 24. At this time, only pin 211 is in working condition. There are 16 pins 211, which are evenly distributed around the circumference of connecting plate 23, in order to meet the condition when the number of stator core slots is 16.

Two stops are provided at the end of the connecting pipe 35 near the spindle 14, arranged axially along the spindle 14, with space between the stops for the feed strip to pass through. A cavity adapted to the trigger shaft 36 is provided inside the connecting pipe 35, which is rotatably positioned within the cavity. The cutting block 38 is slidably positioned within the connecting pipe 35 along the axial direction of the spindle 14. A limiting shaft 381 is fixedly provided at one end of the cutting block 38 near the trigger shaft 36. A trigger groove 361 adapted to the limiting shaft 381 is provided at one end of the trigger shaft 36 near the cutting block 38. The limiting shaft 381 is slidably disposed in the trigger groove 361. The trigger groove 361 is divided into a cutting part and a reset part. The distance between the cutting part of the trigger groove 361 and the axis of the trigger shaft 36 is less than the distance between the reset part of the trigger groove 361 and the axis of the trigger shaft 36. So that when the trigger shaft 36 rotates, when the limiting shaft 381 moves to the cutting part of the trigger groove 361, it drives the cutting block 38 to move in the direction of the axis of the trigger shaft 36.

[0078] Reference Figure 3 , Figure 9 , Figure 19 and Figure 20The fixing member 34 is fixedly installed at the end of the trigger shaft 36 away from the spindle 14. A transmission rod 341 is fixedly installed on the fixing member 34. A through groove is opened on the mounting plate 01, and the transmission rod 341 extends to the rear of the mounting plate 01 through the through groove. The motor 31 is fixedly installed at the rear of the mounting plate 01. The lead screw 32 is fixedly connected to the output end of the motor 31. The transmission block 33 is slidably installed on the mounting plate 01. The transmission block 33 is screwed with the lead screw 32. A through hole is opened on the transmission block 33. The transmission rod 341 extends into the through hole of the transmission block 33 and can move freely within a certain range within the through hole of the transmission block 33. The motor drives the transmission block 33 to move through the lead screw. The movement of the transmission block 33 drives the transmission rod 341 to move, so as to drive the trigger shaft 36 to rotate in the connecting tube 35 through the fixing member 34.

[0079] Reference Figure 2 and Figure 3 A connector 8 is fixedly installed on the side of the connecting plate 1 23 away from the connecting plate 24. The connector 8 is located inside the spindle 14. The connector 8 includes a connecting shaft 81, a positioning rod 4 82 and a fixing plate 83. The fixing plate 83 is fixedly installed at the end of the connecting shaft 81 near the connecting plate 1 23 and is coaxially fixed to the connecting plate 1 23 by a nut. The connecting shaft 81 is coaxially connected to the fixing plate 83. The positioning rod 4 82 is slidably installed on the connecting shaft 81 along the radial direction of the connecting shaft 81, and an elastic element 3 is provided between the positioning rod 4 82 and the connecting shaft 81 to make the positioning rod 4 82 move away from the connecting shaft 81. Multiple connecting rods 22 are provided. In this embodiment, three connecting rods 22 are provided. A fixing plate 141 is provided at the end of the spindle 14 away from the connecting plate. The fixing plate 141 extends radially along the spindle 14, and the side of the fixing plate 141 near the connecting plate abuts against the side of the connecting shaft 81 away from the connecting plate. The fixing plate 141 is fixedly connected to the connecting shaft 81 by a nut. When installing or removing the spindle 14, the spindle 14 is sleeved on the outside of the connecting shaft 81, and the spindle 14 is initially positioned and supported by multiple connecting rods 22. Then the spindle 14 is pushed to abut against the connecting plate. At the same time, when the fixing plate 141 abuts against the connecting shaft 81, the fixing plate 141 is fixedly connected to the connecting shaft 81 by a nut, thereby fixing the spindle 14 on the connecting disc 23.

[0080] Reference Figure 2 and Figure 3As shown, a guide plate 9 is fixedly mounted on the mounting plate 01. The guide plate 9 is positioned in front of the cutting assembly 3, meaning the cutting assembly 3 is located between the guide plate 9 and the mounting plate 01. The cutting assembly 3 is arc-shaped on the side closest to the mandrel 14 and is arranged around the mandrel 14. The lower end face of the cutting assembly 3 is in contact with the end face of the guide block 11 away from the mounting plate 01. A guide groove 2 116 is provided on the side of the pre-bent portion of the guide block 11 away from the mounting plate 01. The guide groove 2 116 is set as an inclined surface so that when the strip is wound through the guide groove 2 116, it acts on the inclined surface of the guide groove 2 116 and moves away from the mounting plate 01. Then, as the strip continues to wind, it moves to the position below the guide plate 9, and the winding operation continues on the side of the guide plate 9 away from the mounting plate 01. By setting up the guide groove 2 116 and the guide plate 9, the strip material passing through the cutting component 3 moves in front of the guide plate 9, avoiding multiple layers of strip material at the cutting component 3, which would cut multiple layers of strip material at the same time during cutting and affect the processing quality.

[0081] Reference Figure 2 and Figure 3 Both guide component 12 and guide component 2 13 are rotatably mounted on the mounting plate 01, and both are movable structures, so the positions of guide component 12 and guide component 2 13 can be adjusted according to the working conditions.

[0082] When the strip is side-wound on the mandrel 14, the total bending deformation of the strip includes both elastic deformation and plastic deformation. The plastic deformation forms the arc after side-wound, and the elastic deformation will elastically recover after side-wound, which makes the side-wound diameter of the strip expand. Therefore, the diameter of the mandrel 14 is set to be smaller than the inner diameter of the iron core.

[0083] Reference Figure 1 and Figure 2 As shown, the aforementioned iron core winding equipment has two sets on the mounting plate 01, and the two sets of iron core winding equipment are identical.

[0084] A method for winding generator cores, using generator core winding processing equipment.

[0085] The implementation principle of this invention is as follows: the unprocessed strip is introduced into the guide block 11, the strip is pre-bent by the pre-bending part of the guide block 11, and then moves to the guiding part of the guide block 11 by the limiting of the guide member 12. The rotating pin 21 moves into the slot of the strip through the relief groove 114 of the guide block 11, driving the strip to wind around the mandrel 14. The strip passes through the limiting of the guide member 2 13 and passes through the cutting component 3. When a core is wound, the strip is cut by the cutting component 3. When it is necessary to process strips of different specifications, the pin component 2 is adjusted by the adjusting component 4 to meet different working conditions.

[0086] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
