Description

Technical Field

[0001] This invention belongs to the field of new energy vehicle motor processing technology, specifically referring to a motor rotor winding device. Background Technology

[0002] Currently, new energy vehicles have become the core direction of the automotive industry's transformation. As one of the core components of new energy vehicles, the performance of the drive motor directly determines the vehicle's range, acceleration, charging efficiency, and safety level. The rotor, as the main rotating component of the new energy vehicle motor, plays a crucial role in the motor's performance and efficiency. The rotor winding process is one of the key steps in motor manufacturing. Precise winding processes ensure that parameters such as the number of turns, wire diameter, and arrangement of the rotor coils meet design requirements, thereby improving the electromagnetic performance and operating efficiency of the new energy vehicle motor.

[0003] When winding a rotor, if the rotor is long, the length of the winding arm usually needs to be increased to cover the entire winding area and ensure that the enameled wire is accurately wound on the rotor. This ensures that the winding arm can cover all winding positions of the rotor during rotation. Conversely, if the rotor is short, the winding arm does not need to be too long. Otherwise, it may lead to inaccurate positioning of the enameled wire during winding or interference between the winding arm and other parts of the rotor. In the existing technology, the length of the winding arm cannot be adjusted according to the rotor length. When winding rotors of different lengths, the length of the winding arm needs to be manually increased or decreased, which is very inconvenient. In addition, if the rotor is not fixed securely during winding, it is easy to cause poor winding and affect the rotor performance. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a motor rotor winding device that can automatically adjust the winding radius according to the rotor length to ensure that the enameled wire is accurately wound on the rotor.

[0005] The technical solution adopted by this invention is as follows: This invention provides a motor rotor winding device, including a machine base. The machine base is provided with a self-centering clamping mechanism for clamping the rotor along its axis. The machine base is also provided with a vertical guiding mechanism and a self-adjusting winding mechanism, which are arranged circumferentially around the self-centering clamping mechanism. The self-adjusting winding mechanism is slidably mounted on the machine base along the Y-axis. The self-adjusting winding mechanism is provided with a telescopic winding arm. The machine base is provided with a positioning mechanism for clamping the rotor along the axial direction. The positioning mechanism is connected to the self-centering clamping mechanism and drives the self-centering clamping mechanism to move. A linkage component is provided between the self-centering clamping mechanism and the self-adjusting winding mechanism to drive the telescopic winding arm to extend and retract. When the positioning mechanism moves along the rotor axial direction to clamp the rotor, it drives the self-adjusting winding mechanism to slide synchronously along the Y-axis direction, so that the self-adjusting winding mechanism automatically aligns with the center of the rotor. When the self-adjusting winding mechanism moves, the winding radius is automatically adjusted by the linkage component.

[0006] Furthermore, the self-adjusting winding mechanism includes a winding frame, a main shaft, and a fly fork. The main shaft rotatably passes through the winding frame, and the winding frame is equipped with a winding drive that is connected to and drives the main shaft to rotate. The fly fork is fixedly connected to the main shaft. The telescopic winding arm includes a fixed arm fixed to the side wall of the fly fork and a sliding arm slidably connected to the fixed arm. The linkage assembly includes a push ring assembly, a push hinge, and a follower push assembly. The push ring assembly is slidably sleeved on the outside of the fly fork and is coaxially arranged with the main shaft. The push ring assembly includes an adjusting outer ring that rotates relative to the fly fork and an adjusting inner ring that rotates synchronously with the fly fork. The adjusting outer ring is slidably connected to the winding frame. The inner ring is coaxially rotatably disposed within the outer ring of the adjustment mechanism. A matching sliding sleeve is slidably fitted onto the fly fork. The sliding sleeve is fixedly connected to the inner ring of the adjustment mechanism. A self-adjusting tension spring is provided between the outer ring of the adjustment mechanism and the winding frame. The self-adjusting tension spring causes the outer ring of the adjustment mechanism to tend to slide away from the telescopic winding arm. The side wall of the inner ring of the adjustment mechanism is provided with a hinge seat. The two ends of the push hinge rod are rotatably connected to the hinge seat and the sliding arm, respectively. The bottom wall of the outer ring of the adjustment mechanism is provided with a self-adjusting push rod. The follower push assembly abuts against the self-adjusting push rod and pushes the self-adjusting push rod to slide along the axial direction of the main shaft. The main shaft is provided with a first threading channel. The telescopic winding arm is provided with a second threading channel. The first threading channel and the second threading channel are connected.

[0007] More specifically, the winding frame is symmetrically provided with self-adjusting sleeves on both sides, and the outer side of the adjusting outer ring is symmetrically provided with self-adjusting sliding shafts. The self-adjusting sliding shafts are slidably locked inside the self-adjusting sleeves. The adjusting outer ring is slidably connected to the winding frame through the self-adjusting sliding shafts and is rotatably set relative to the flying fork. The self-adjusting tension spring is provided between the adjusting outer ring and the self-adjusting sleeves.

[0008] The winding drive includes a winding motor, gear one, and gear two. The winding motor is mounted on the winding frame. Gear one is located at the output end of the winding motor. Gear two is coaxially sleeved on the outside of the main shaft. Gear one and gear two mesh. A cover is provided on the outside of gear one and gear two. The winding motor drives the main shaft to rotate through gear one and gear two.

[0009] The following push assembly includes an L-shaped slide rod and an inclined baffle. The bottom wall of the self-centering clamping mechanism is provided with a first slide groove arranged along the X-axis. The bottom wall of the winding frame is provided with a mounting seat. The bottom wall of the mounting seat is provided with a second slide groove arranged along the Y-axis. The two ends of the L-shaped slide rod are respectively slidably disposed in the first slide groove and the second slide groove. The bottom wall of the L-shaped slide rod is provided with a U-shaped bracket parallel to the second slide groove. The inclined baffle is disposed on the side of the U-shaped bracket near the self-centering clamping mechanism. The side of the inclined baffle near the self-centering clamping mechanism is inclined. The self-adjusting push rod is disposed between the inclined baffle and the self-centering clamping mechanism.

[0010] The self-adjusting winding mechanism slides along the Y-axis, causing the winding frame to move along the Y-axis. The winding frame drives the second slide groove to slide along the L-shaped slide bar. During this process, the L-shaped slide bar does not move in the X-axis direction, the inclined baffle remains fixed, and the winding frame drives the self-adjusting push rod to move relative to the inclined baffle. The inclined baffle causes the self-adjusting push rod to drive the adjusting outer ring to slide along the X-axis direction. The adjusting outer ring drives the adjusting inner ring to slide. The adjusting inner ring drives the telescopic winding arm to extend and retract through the push hinge rod.

[0011] Furthermore, the machine base is provided with a mounting frame, and the positioning mechanism includes a fixed sliding shaft, a movable sliding shaft, an X-type telescopic bracket, a movable limit block, and a drive assembly. The mounting frame is provided with a fixed limit block that cooperates with the movable limit block. The machine base has a mounting groove in the middle, and the fixed sliding shaft is fixedly installed in the mounting groove. The two side walls of the mounting groove are symmetrically provided with limit sliding grooves, and limit sliders are slidably installed in the limit sliding grooves. The movable sliding shaft is located between the limit sliders and is parallel to the fixed sliding shaft. The X-type telescopic bracket... The telescopic support is located between the fixed slide shaft and the movable slide shaft and pushes the movable slide shaft to slide. A connecting frame is provided on one side of the limiting slider. A support frame is provided above the connecting frame. The movable limiting block is located above the support frame. The movable limiting block and the fixed limiting block are at the same horizontal height and symmetrically arranged on both sides of the X-type telescopic support. A central shaft is provided in the middle of the X-type telescopic support. The drive assembly is located on the machine base. A connecting rod is provided at the output end of the drive assembly. The drive assembly adopts a drive cylinder. The connecting rod is connected to the central shaft and connected to the self-adjusting winding mechanism.

[0012] The self-centering clamping mechanism includes an angle-adjusting motor, a turntable, multiple arc-shaped clamping plates equidistantly distributed along the circumference of the turntable, and a clamping drive assembly that drives all the arc-shaped clamping plates to move synchronously radially. The angle-adjusting motor is fixedly mounted on the mounting frame, and its output shaft is connected to the turntable and drives the turntable to rotate. The arc-shaped clamping plates are slidably arranged along the radial direction of the turntable. A clamping push spring is provided between the turntable and the arc-shaped clamping plates. The clamping drive assembly is mounted on the mounting frame. The clamping drive assembly includes a clamping cylinder, a clamping push plate, a clamping outer ring, and a clamping inner ring. The clamping cylinder is located on the bottom wall of the mounting frame, and a through-hole is provided on the mounting frame. The clamping cylinder and the pushing through hole are arranged parallel to the axis of the turntable. The bottom end of the clamping push plate is located at the output end of the clamping cylinder, and the upper end of the clamping push plate slides through the pushing through hole. The clamping outer ring is fixedly located at the upper end of the clamping push plate, and the clamping inner ring is rotatably located inside the clamping outer ring. The clamping outer ring, the clamping inner ring, and the turntable are arranged coaxially. Multiple arc-shaped clamping plates are located inside the clamping inner ring. The inner circumferential sidewall of the clamping inner ring is provided with equidistant locking shafts. The end of the locking shaft is provided with a pushing locking ball. The outer sidewall of the arc-shaped clamping plate is provided with an oblique sliding groove along the length direction. The distance from the oblique sliding groove to the axis of the turntable gradually decreases. The pushing locking ball is embedded in and abuts against the oblique sliding groove.

[0013] More specifically, the turntable is coaxially fixed to the output shaft of the angle adjustment motor. Guide shafts are equidistantly distributed on the circumferential sidewalls of the turntable. A guide sleeve is provided on one side of the arc-shaped clamping plate and slidably connected to the guide shaft. The arc-shaped clamping plate is slidably arranged radially along the turntable through the guide sleeve and the guide shaft. The clamping push spring is located between the turntable and the guide sleeve. A triangular push plate is provided along the length direction on the outer sidewall of the arc-shaped clamping plate. An inclined slide groove is provided on the sidewall of the triangular push plate. The triangular push plate provides a stable mounting carrier for the inclined slide groove. A horizontal slide groove is connected to the end of the inclined slide groove away from the guide shaft. The horizontal slide groove is parallel to the axis of the turntable. The height from the end of the inclined slide groove near the guide shaft to the sidewall of the arc-shaped clamping plate is greater than the height from the end of the inclined slide groove away from the guide shaft to the sidewall of the arc-shaped clamping plate. The cross-section of the inclined slide groove and the cross-section of the horizontal slide groove are arranged in an inverted T shape.

[0014] The clamping springs cause multiple sets of arc-shaped clamping plates to always tend to slide away from the turntable axis along the guide shaft, i.e., the multiple sets of arc-shaped clamping plates separate from each other. This ensures that the oblique grooves on the side walls of the arc-shaped clamping plates are always in contact with the pushing ball. By controlling the contraction of the clamping cylinder, the clamping push plate is driven to slide along the pushing through hole. The clamping push plate drives the clamping outer ring and clamping inner ring to slide along the turntable axis and approach the guide shaft. The clamping inner ring drives the pushing ball to slide along the oblique groove. Since the distance between the pushing ball and the turntable axis remains constant, when the pushing ball slides, it pushes the arc-shaped clamping plates along the guide shaft through the oblique groove to move closer to the turntable axis against the elastic force of the clamping spring. This allows multiple sets of arc-shaped clamping plates to move closer to each other synchronously, which is convenient for centering and clamping rotors of different sizes and for facilitating stable winding of the rotor.

[0015] Furthermore, the vertical guiding mechanism includes a bidirectional lead screw, an adjusting guide rod, a vertical motor, an upper guide assembly, and a lower guide assembly. The adjusting guide rod and the bidirectional lead screw pass through the mounting frame, and the bidirectional lead screw is rotatably connected to the mounting frame. The upper guide assembly and the lower guide assembly are symmetrically arranged on both sides of the self-centering clamping mechanism, that is, the upper guide assembly and the lower guide assembly are symmetrically arranged on the upper and lower sides of the turntable to facilitate centering clamping. The upper guide assembly and the lower guide assembly are slidably connected to the adjusting guide rod, and the two ends of the bidirectional lead screw are symmetrically provided with threaded portions with opposite directions. The upper guide assembly and the lower guide assembly are threadedly connected to the threaded portions at both ends of the bidirectional lead screw, and the output end of the vertical motor is connected to the bidirectional lead screw and drives the bidirectional lead screw to rotate.

[0016] More specifically, the mounting frame is provided with a vertical through hole, the middle part of the adjusting guide rod is connected to a middle partition plate, the upper and lower ends of the adjusting guide rod are respectively provided with a top plate and a bottom plate, the middle part of the bidirectional lead screw rotates through the middle partition plate, the lower end of the bidirectional lead screw rotates through the vertical through hole and is located below the mounting frame, the vertical motor is located on the top plate, and the upper guide assembly and the lower guide assembly are respectively slidably located on the upper and lower sides of the middle partition plate.

[0017] A vertical motor drives a bidirectional lead screw to rotate. When the bidirectional lead screw rotates, the upper guide assembly and the lower guide assembly move towards each other or move away from each other through the opposite threads at both ends. By adjusting the distance between the upper guide assembly and the lower guide assembly, it is possible to guide and center rotors of different sizes.

[0018] More specifically, the lower guide assembly includes a threaded slide, an L-shaped carriage, and a guide plate. The threaded slide is slidably mounted on the adjusting guide rod and is threadedly connected to the bidirectional lead screw. The L-shaped carriage is located on the side of the threaded slide near the turntable, and the guide plate is located at the end of the L-shaped carriage. The guide plate is triangular in shape, and the side of the guide plate near the turntable is arc-shaped. The axis of the arc-shaped sidewall is parallel to the axis of the turntable. The upper guide assembly has the same structure as the lower guide assembly. The threaded slides of the upper guide assembly and the lower guide assembly are threadedly connected to the threaded portions at the upper and lower ends of the bidirectional lead screw, respectively.

[0019] Furthermore, the self-adjusting winding mechanism also includes an adjustable bracket, which includes a first guide rail, a mounting slide, a mounting plate, a second guide rail, and a pushing cylinder. The first guide rail is mounted on the machine platform along the Y-axis, the mounting slide is slidably mounted on the first guide rail, the mounting plate is mounted on the upper end of the mounting slide, the second guide rail is mounted on the mounting plate along the X-axis, the winding frame is slidably mounted on the second guide rail, and the pushing cylinder is mounted on the mounting plate. The pushing cylinder is connected to the winding frame and pushes the winding frame to slide along the second guide rail. The mounting plate is provided with a clearance groove, and the mounting seat is slidably mounted in the clearance groove.

[0020] Preferably, the mounting groove is located in front of the self-centering clamping mechanism, the vertical guide mechanism is symmetrically located on the upper and lower sides of the self-centering clamping mechanism, the self-adjusting winding mechanism is symmetrically located on both sides of the mounting groove, the mounting groove is symmetrically provided with fixed supports on the side near the turntable, and the fixed sliding shaft is located between the fixed supports.

[0021] More specifically, the X-type telescopic bracket includes a first hinge and a second hinge rotatably connected at the center via a central axis. The first hinge has a guide slide 1 rotatably mounted at its end near the turntable, and the guide slide 1 is slidably connected to a fixed slide shaft. The second hinge has a guide slide 2 rotatably mounted at its end near the turntable, and the guide slide 2 is slidably connected to the fixed slide shaft. The first hinge has a guide slide 3 rotatably mounted at its end away from the turntable, and the guide slide 3 is slidably connected to a movable slide shaft. The second hinge has a guide slide 4 rotatably mounted at its end away from the turntable, and the guide slide 4 is slidably connected to the movable slide shaft. The length from the movable limit block to the fixed slide shaft is equal to the length from the fixed limit block to the movable slide shaft. The axis of the main shaft and the axis of the central shaft are in the same plane, and this plane is perpendicular to the upper wall of the machine platform.

[0022] The drive assembly moves the connecting rod, which in turn drives the X-type telescopic bracket to extend and retract via the central shaft. When the central shaft moves closer to the turntable, it drives the first and second hinge rods to rotate, causing guide slide one and guide slide two to slide away from each other along the fixed slide shaft, and guide slide three and guide slide four to slide away from each other along the moving slide shaft. This causes the moving slide shaft and the limiting slider to move along the limiting slide groove closer to the turntable. The limiting slider, through the support frame, causes the moving limiting block to move closer to the rotor and the fixed limiting block, thereby fixing the rotor between the moving and fixed limiting blocks. The limiting slider, through the connecting frame, drives the support frame and the moving limiting block to move closer to the fixed limiting block. The distance from the central shaft to the fixed slide shaft is always equal to the distance from the central shaft to the moving slide shaft, and thus the distance from the central shaft to the moving limiting block is always equal to the distance from the central shaft to the fixed limiting block. As a result, the main shaft is always located at the midpoint of the line connecting the fixed and moving limiting blocks. The X-type telescopic bracket and the connecting rod achieve automatic centering adjustment of the main shaft position.

[0023] Preferably, the support frame includes a fixed rod, a follower connecting rod, a crossbar, and a sliding sleeve rod slidably connected to the fixed rod. The fixed rod is located in the middle of the frame, the crossbar is located at the top of the sliding sleeve rod, the movable limiting block is located at the end of the crossbar near the fixed limiting block, the follower connecting rod is located on the side of the sliding sleeve rod near the lower guide assembly, the L-shaped carriage sidewall of the lower guide assembly is provided with a follower sliding hole, the follower connecting rod passes through the follower sliding hole, the guide plate of the lower guide assembly is provided with an avoidance slot in the middle along the length direction, and the crossbar is slidably located in the avoidance slot.

[0024] Preferably, the sliding sleeve is hollow and extends vertically, and is slidably sleeved on the upper end of the fixed rod.

[0025] When the lower guide assembly moves up and down, it drives the sliding sleeve rod to move up and down along the fixed rod through the follower sliding hole and follower connecting rod, so that the moving limit block and the fixed limit block always remain at the same horizontal height. At the same time, the follower connecting rod that is slidably connected to the lower guide assembly will not affect the X-type telescopic bracket from driving the support frame to move closer to the fixed limit block.

[0026] Preferably, pressure sensors are provided on the side wall of the moving limit block and the inner wall of the arc-shaped clamping plate, respectively. A controller is provided on the machine base. The controller is electrically connected to the pressure sensors and the drive cylinder. When the moving limit block and the fixed limit block are tightly fitted with both sides of the rotor, the pressure sensor on the side wall of the moving limit block is pressed and sends a signal to the controller. The controller controls the drive cylinder to stop contracting, thereby fixing the rotor between the moving limit block and the fixed limit block. By clamping both sides of the rotor, automatic centering adjustment of the spindle can be easily achieved. When the arc-shaped clamping plate is tightly fitted with the rotor shaft, the pressure sensor on the inner wall of the arc-shaped clamping plate is pressed and sends a signal to the controller. The controller controls the clamping cylinder to stop contracting.

[0027] The self-adjusting winding mechanism further includes a die head, and synchronous belt pulley transmission assemblies are respectively provided at both ends of the fly fork. A fixed sleeve is provided at the end of the main shaft, and the die head is located at the end of the fixed sleeve. The synchronous belt pulley transmission assembly at the end of the fly fork away from the winding frame is connected to the fixed sleeve, and the synchronous belt pulley transmission assembly at the end of the fly fork close to the winding frame is connected to the winding frame.

[0028] More specifically, the synchronous belt pulley drive assembly includes a pulley one, a pulley two, and a belt. Pulley one and pulley two are connected by belt drive. Pulley one is rotatably sleeved on the main shaft. The pulley one at the end of the fly fork near the winding frame is fixedly connected to the winding frame. The pulley one at the end of the fly fork away from the winding frame is coaxially fixedly connected to the fixed sleeve. A pulley shaft is rotatably provided on one side of the fly fork. Pulley two is coaxially provided at both ends of the pulley shaft.

[0029] The main shaft drives the fly fork to rotate. Since the pulley one at one end of the fly fork is fixed relative to the fly fork, the fly fork drives the pulley two to rotate around the pulley one. As a result, the pulley one at the other end is also fixed relative to the fly fork and will not move with the rotation of the main shaft. This ensures that the die head set on the fixed sleeve will not move, and at the same time improves stability and prevents the die head from shaking due to the rotation of the fly fork, which would affect the winding quality.

[0030] The beneficial effects achieved by the present invention using the above structure are as follows:

[0031] 1. The X-type telescopic bracket extends and retracts, causing the support frame and the moving limit block to move closer to the rotor, thereby positioning the rotor between the fixed limit block and the moving limit block. At the same time, the connecting rod drives two sets of symmetrically arranged self-adjusting winding mechanisms to slide synchronously along the Y-axis. Through the symmetrical telescopic structure of the X-type telescopic bracket, the self-adjusting winding mechanism automatically aligns with the center of the rotor.

[0032] 2. Through the linkage structure of X-type telescopic bracket, connecting rod, inclined baffle and self-adjusting push rod, the technical effect of automatic adjustment of the telescopic winding arm length with the rotor length is achieved. The inclined baffle converts the movement in the Y-axis direction to the movement in the X-axis direction, pushes the adjusting outer ring, and then controls the extension and retraction of the telescopic winding arm by pushing the hinge rod to achieve automatic adjustment of the winding radius.

[0033] 3. The structure of pushing ball and oblique sliding groove is adopted to realize the synchronous radial movement of multiple sets of arc-shaped clamping plates, which can adapt to rotors of different diameters and realize the stable clamping and fixing of the rotor.

[0034] 4. The upper and lower guide components, which are symmetrically positioned, are driven to move synchronously by a two-way lead screw, so that the two sets of guide plates can move synchronously towards or away from each other, adapting to rotors of different heights and facilitating the centering and clamping of the rotor.

Therefore, they should not be construed as limitations on this invention.

[0053] like Figures 1-14 As shown, the present invention provides a motor rotor winding device, including a machine base 1. The machine base 1 is equipped with a self-centering clamping mechanism 3 for clamping the rotor along its axis. The machine base 1 also includes a vertical guide mechanism 4 and a self-adjusting winding mechanism 6, which are arranged circumferentially around the self-centering clamping mechanism 3. The self-adjusting winding mechanism 6 is slidably mounted on the machine base 1 along the Y-axis and is equipped with a telescopic winding arm. The machine base 1 is equipped with an axial clamping mechanism. The positioning mechanism for holding the rotor is connected to the self-centering clamping mechanism 3 and drives the self-centering clamping mechanism 3 to move. A linkage component for driving the telescopic winding arm to extend and retract is provided between the self-centering clamping mechanism 3 and the self-adjusting winding mechanism 6. When the positioning mechanism moves along the rotor axis to clamp the rotor, it drives the self-adjusting winding mechanism 6 to slide synchronously along the Y-axis, so that the self-adjusting winding mechanism 6 automatically aligns with the center of the rotor. When the self-adjusting winding mechanism 6 moves, the winding radius is automatically adjusted by the linkage component.

[0054] The machine base 1 is equipped with a mounting frame 2. The self-centering clamping mechanism 3 includes an angle adjustment motor 46, a turntable 51, multiple arc-shaped clamping plates 52 equidistantly distributed along the circumference of the turntable 51, and a clamping drive assembly that drives all the arc-shaped clamping plates 52 to move synchronously along the radial direction. The angle adjustment motor 46 is fixedly mounted on the mounting frame 2. The output shaft of the angle adjustment motor 46 is connected to the turntable 51 and drives the turntable 51 to rotate.

A clamping push spring 55 is provided between the turntable 51 and the arc-shaped clamping plates 52. The clamping drive assembly is mounted on the mounting frame 2. The clamping drive assembly includes a clamping cylinder 47, a clamping push plate 48, a clamping outer ring 49, and a clamping inner ring 50. The clamping cylinder 47 is located on the bottom wall of the mounting frame 2. A push-through hole is provided through the mounting frame 2. 56. The clamping cylinder 47 and the pushing through hole 56 are arranged parallel to the axis of the turntable 51. The bottom end of the clamping push plate 48 is located at the output end of the clamping cylinder 47. The upper end of the clamping push plate 48 slides through the pushing through hole 56. The clamping outer ring 49 is fixedly located at the upper end of the clamping push plate 48. The clamping inner ring 50 is rotatably located inside the clamping outer ring 49. The clamping outer ring 49, the clamping inner ring 50 and the turntable 51 are arranged coaxially. Multiple arc-shaped clamping plates 52 are located inside the clamping inner ring 50. The inner circumferential sidewall of the clamping inner ring 50 is provided with equidistant locking shafts 57. The end of the locking shaft 57 is provided with a pushing locking ball 58. The outer sidewall of the arc-shaped clamping plate 52 is provided with an inclined sliding groove 60 along the length direction. The distance from the inclined sliding groove 60 to the axis of the turntable 51 gradually decreases. The pushing locking ball 58 is embedded in and abuts against the inclined sliding groove 60.

[0055] In some embodiments, the turntable 51 is coaxially fixed to the output shaft of the angle adjustment motor 46. Guide shafts 53 are equidistantly distributed on the circumferential sidewalls of the turntable 51. A guide sleeve 54, slidably connected to the guide shafts 53, is provided on one side of the arc-shaped clamping plate 52. The arc-shaped clamping plate 52 slides radially along the turntable 51 via the guide sleeve 54 and the guide shafts 53. The clamping spring 55 is located between the turntable 51 and the guide sleeve 54. The outer sidewall of the arc-shaped clamping plate 52 is provided along its length... A triangular sliding plate 59 is provided, and an inclined slide 60 is provided on the side wall of the triangular sliding plate 59. The end of the inclined slide 60 away from the guide shaft 53 is connected to a horizontal slide 61. The horizontal slide 61 is parallel to the axis of the turntable 51. The height of the inclined slide 60 from the end near the guide shaft 53 to the side wall of the arc-shaped clamp 52 is greater than the height of the end of the inclined slide 60 away from the guide shaft 53 to the side wall of the arc-shaped clamp 52. The cross-section of the inclined slide 60 and the cross-section of the horizontal slide 61 are arranged in an inverted T shape.

[0056] The clamping spring 55 ensures that the multiple sets of arc-shaped clamping plates 52 always tend to slide away from the axis of the turntable 51 along the guide shaft 53, i.e., the multiple sets of arc-shaped clamping plates 52 separate from each other. This ensures that the oblique groove 60 on the side wall of the arc-shaped clamping plate 52 always abuts against the pushing ball 58. By controlling the contraction of the clamping cylinder 47, the clamping push plate 48 is driven to slide along the pushing through hole 56. The clamping push plate 48 drives the clamping outer ring 49 and the clamping inner ring 50 to slide along the axis of the turntable 51 and approach the guide shaft 53. 3. The inner clamping ring 50 drives the pusher ball 58 to slide along the inclined groove 60. Since the distance between the pusher ball 58 and the axis of the turntable 51 remains unchanged, when the pusher ball 58 slides, it pushes the arc-shaped clamping plate 52 along the guide shaft 53 to overcome the elastic force of the clamping spring 55 and move closer to the axis of the turntable 51 through the inclined groove 60. This allows multiple sets of arc-shaped clamping plates 52 to move closer to each other synchronously, which is convenient for centering and clamping rotors of different sizes and for facilitating stable winding of the rotor.

The second pulley 38 is coaxially provided at both ends of the pulley shaft 40.

[0060] The main shaft 14 drives the fly fork 15 to rotate. Since the pulley 37 at one end of the fly fork 15 is fixed relative to the fly fork 15, the fly fork 15 drives the pulley 38 to rotate around the pulley 37. As a result, the pulley 37 at the other end is also fixed relative to the fly fork 15 and will not move with the rotation of the main shaft 14. This ensures that the die head 16 set on the fixed sleeve 19 will not move, and at the same time improves stability and prevents the die head 16 from shaking due to the rotation of the fly fork 15, which would affect the winding quality.

The fixed sliding shaft 76 is located between the fixed supports 78. The X-type telescopic bracket 9 includes a first hinge rod 74 and a second hinge rod 75 rotatably connected in the middle by a central shaft 10.

A guide slide 2 80 is rotatably provided at the end of the first hinge rod 75 near the turntable 51. The guide slide 2 80 is slidably connected to the fixed slide shaft 76.

[0070] The support frame 95 includes a fixed rod 86, a follower connecting rod 88, a crossbar 89, and a sliding sleeve rod 87 slidably connected to the fixed rod 86. The fixed rod 86 is located in the middle of the connecting frame 83, the crossbar 89 is located at the top of the sliding sleeve rod 87, the movable limit block 12 is located at the end of the crossbar 89 near the fixed limit block 11, the follower connecting rod 88 is located on the side of the sliding sleeve rod 87 near the lower guide assembly 66, the side wall of the L-shaped slide 71 of the lower guide assembly 66 is provided with a follower sliding hole 90, the follower connecting rod 88 passes through the follower sliding hole 90, the guide support plate 72 of the lower guide assembly 66 is provided with an avoidance slot 91 in the middle along the length direction, and the crossbar 89 is slidably located in the avoidance slot 91.

[0071] In this embodiment, the sliding sleeve 87 is hollow and extends vertically, and is slidably sleeved on the upper end of the fixed rod 86.

[0072] When the lower guide assembly 66 moves up and down, it drives the sliding sleeve 87 to move up and down along the fixed rod 86 through the follower sliding hole 90 and the follower connecting rod 88, so that the moving limit block 12 and the fixed limit block 11 always remain at the same horizontal height. At the same time, the follower connecting rod 88, which is slidably connected to the lower guide assembly 66, will not affect the X-type telescopic bracket 9 from driving the support frame 95 to move closer to the fixed limit block 11.

[0073] Pressure sensors 92 are respectively provided on the side wall of the moving limit block 12 and the inner wall of the arc-shaped clamping plate 52. A controller 93 is provided on the machine base 1. The controller 93 is electrically connected to the pressure sensors 92 and the drive cylinder. When the moving limit block 12 and the fixed limit block 11 are tightly fitted with the two sides of the rotor, the pressure sensor 92 on the side wall of the moving limit block 12 is pressed and sends a signal to the controller 93. The controller 93 controls the drive cylinder to stop contracting, thereby fixing the rotor between the moving limit block 12 and the fixed limit block 11. By clamping the two sides of the rotor, the automatic centering adjustment of the main shaft 14 can be easily realized. When the arc-shaped clamping plate 52 is tightly fitted with the rotor shaft, the pressure sensor 92 on the inner wall of the arc-shaped clamping plate 52 is pressed and sends a signal to the controller 93. The controller 93 controls the clamping cylinder 47 to stop contracting. The controller 93 and the pressure sensor 92 are existing technologies and will not be described in detail here.

[0074] In practical use, firstly, adjust the distance between the upper guide assembly 65 and the lower guide assembly 66 according to the size of the rotor. Start the vertical motor 64, which drives the bidirectional lead screw 62 to rotate. When the bidirectional lead screw 62 rotates, it drives the upper guide assembly 65 and the lower guide assembly 66 to move towards each other or away from each other through the opposite threads at both ends. By adjusting the distance between the upper guide assembly 65 and the lower guide assembly 66, it is convenient to guide and clamp rotors of different sizes. When the lower guide assembly 66 moves up and down, it drives the sliding sleeve 87 to move up and down along the fixed rod 86 through the following sliding hole 90 and the following connecting rod 88, so that the moving limit block 12 and the fixed limit block 11 always remain at the same horizontal height. At the same time, it moves up and down with the lower guide assembly 66. The sliding connection of component 66 with follower link 88 will not affect the movement of X-type telescopic bracket 9 to support frame 95 closer to positioning block 11. The distance between upper guide component 65 and lower guide component 66 is optimal so that the upper and lower sides of the rotor contact the guide support plate 72 of upper guide component 65 and guide support plate 72 of lower guide component 66 respectively, and the rotor can slide between the two guide support plates 72. Then, the rotor is placed between the guide support plate 72 of upper guide component 65 and guide support plate 72 of lower guide component 66 through mechanical grippers (existing technology). The enameled wire is passed out from the first wire passage 94 and the second wire passage 73, and the end of the enameled wire is wound around the rotor. Then, the drive cylinder is controlled to retract, and the drive cylinder drives link 7 to move along the Y-axis. The connecting rod 7 drives two symmetrically arranged self-adjusting winding mechanisms 6 to slide synchronously along the Y-axis. At the same time, the connecting rod 7 drives the X-type telescopic bracket 9 to extend and retract through the central shaft 10. The connecting rod 7 drives the central shaft 10 to move closer to the turntable 51. The central shaft 10 drives the first hinge rod 74 and the second hinge rod 75 to rotate, so that the first guide slide 79 and the second guide slide 80 slide away from each other along the fixed slide shaft 76, and the third guide slide 84 and the fourth guide slide 85 slide away from each other along the moving slide shaft 77. This causes the moving slide shaft 77 and the limiting slider 82 to move closer to the turntable 51 along the limiting slide groove 81. The limiting slider 82, through the support frame 95, causes the moving limiting block 12 to move closer to the rotor and the fixed limiting block 11, thereby fixing the rotor to the moving limiting block 12 and the fixed limiting block 11. Between 1 and 2, the limiting slider 82 drives the support frame 95 and the moving limiting block 12 to move closer to the fixed limiting block 11 via the connecting frame 83. When the moving limiting block 12 and the fixed limiting block 11 are tightly fitted with both sides of the rotor, the pressure sensor 92 is pressurized and sends a signal to the controller 93. The controller 93 controls the drive cylinder to stop contracting, thereby fixing the rotor between the moving limiting block 12 and the fixed limiting block 11. The rotor shaft is inserted into multiple sets of arc-shaped clamps 52. Since the distance from the central shaft 10 to the fixed sliding shaft 76 is always equal to the distance from the central shaft 10 to the moving sliding shaft 77, the distance from the central shaft 10 to the moving limiting block 12 and the distance from the central shaft 10 to the fixed limiting block 11 are always equal. Therefore, the main shaft 14 is always located at the midpoint of the line connecting the fixed limiting block 11 and the moving limiting block 12.The automatic centering adjustment of the main shaft 14 is achieved through the X-type telescopic bracket 9 and the connecting rod 7. The connecting rod 7 drives the self-adjusting winding mechanism 6 to slide along the Y-axis, causing the winding frame 13 to move along the Y-axis. The winding frame 13 drives the second slide groove 35 to slide along the L-shaped slide bar 31. During this process, the L-shaped slide bar 31 does not move in the X-axis direction, and the inclined baffle 33 remains fixed. The winding frame 13 drives the self-adjusting push rod 29 to move relative to the inclined baffle 33. The inclined baffle 33 causes the self-adjusting push rod 29 to drive the adjusting outer ring 32 to slide along the X-axis. The adjusting outer ring 32 drives the adjusting inner ring 23 to slide. The adjusting inner ring 23 slides along the fixed arm 20 through the push hinge rod 28, thereby automatically adjusting the length of the telescopic winding arm. The connecting rod 7 drives the self-adjusting push rod 29 to slide along the fixed arm 20. The greater the moving distance of the self-adjusting winding mechanism 6, the farther the inclined baffle 33 pushes the self-adjusting push rod 29 and the adjusting outer ring 32 to move along the X-axis. The closer the adjusting outer ring 32 is to the telescopic winding arm, the greater the moving distance of the adjusting inner ring 23 through the pushing hinge rod 28, the greater the length of the telescopic winding arm, and the larger the winding radius. Then, the clamping cylinder 47 is controlled to retract. Due to the clamping push spring 55, the multiple sets of arc-shaped clamps 52 always have a tendency for the guide shaft 53 to slide away from the axis of the turntable 51, that is, the multiple sets of arc-shaped clamps 52 separate from each other. Thus, the inclined sliding groove 60 on the side wall of the arc-shaped clamp 52 always abuts against the pushing ball 58. The retraction of the clamping cylinder 47 drives the clamping push plate 48 to slide along the pushing through hole 56. The clamping push plate 48 drives the clamping outer ring 49 and the self-adjusting push rod 29 and the adjusting outer ring 32 to move along the X-axis. The clamping inner ring 50 slides along the axis of the turntable 51 towards the guide shaft 53. The clamping inner ring 50 drives the pushing ball 58 to slide along the inclined groove 60. Since the distance between the pushing ball 58 and the axis of the turntable 51 remains constant, the pushing ball 58, as it slides, pushes the arc-shaped clamping plate 52 along the guide shaft 53 through the inclined groove 60, overcoming the elastic force of the clamping spring 55, and moving towards the axis of the turntable 51. This causes multiple sets of arc-shaped clamping plates 52 to move synchronously towards the rotor shaft. When the arc-shaped clamping plate 52 is tightly fitted with the rotor shaft, the pressure sensor 92 on the inner wall of the arc-shaped clamping plate 52 sends a signal to the controller 93. The controller 93 controls the clamping cylinder 47 to stop contracting. The horizontal movement of the clamping inner ring 50 drives multiple sets of arc-shaped clamping plates 52 to move synchronously, facilitating the handling of rotors of different sizes. The centering clamp is fixed to facilitate stable winding of the rotor. After the rotor shaft is clamped, the push cylinder 45 is extended, driving the winding frame 13 to slide along guide rail 44 closer to the rotor. When the die 16 is tightly fitted with the rotor, the push cylinder 45 stops extending, and then the winding drive 17 is activated. The winding drive 17 drives the main shaft 14 to rotate, which in turn drives the fly fork 15 to rotate. Since the pulley 37 at one end of the fly fork 15 is fixed relative to the fly fork 15, the fly fork 15 drives pulley 38 to rotate around pulley 37. Thus, the pulley 37 at the other end is also fixed relative to the fly fork 15 and will not move with the rotation of the main shaft 14. This ensures that the die 16, which is mounted on the fixed sleeve 19, will not move, and also improves stability.To prevent the die head 16 from wobbling due to the rotation of the fly fork 15, which would affect the winding quality, the rotation of the fly fork 15 drives the telescopic winding arm to rotate, and the telescopic winding arm winds the enameled wire into the rotor slot.
