Description

Technical Field

[0001] This invention relates to the field of motor rotor manufacturing technology, and in particular to an automatic winding fixture for starter rotors. Background Technology

[0002] The structure of the engine rotor can be referenced from the patent with announcement number CN211579815U, entitled "A Connection Structure of a Motor Rotor Commutator". This patent describes that the motor rotor includes a shaft, a rotor core sleeved on the shaft, and the rotor core includes N rotor chips. The rotor chips are distributed in a circular interval, and excitation winding slots are opened between adjacent rotor chips. A commutator is also sleeved on the shaft. The commutator includes an insulating sleeve and a commutator segment. The insulating sleeve is sleeved with the shaft and includes a receiving slot and an insulating gap. A commutator segment is arranged in each receiving slot. Enamelled wire is repeatedly wound between two adjacent excitation winding slots, and the first and last ends are welded to the adjacent commutator segments respectively.

[0003] Each rotor has N excitation winding slots, requiring N enameled wires for winding. The existing enameled wire winding method is mostly manual winding. The work requires installing N enameled wires one by one on the excitation winding slots of adjacent rotor chips, and finally welding them to the commutator segments. A worker can complete the winding of about 40 rotors in 8 hours, which is inefficient and has huge labor costs. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies (such as inconvenience of use) by providing a subject name.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] An automatic winding fixture for starter rotors includes a winding body and a rotor clamping and driving component.

[0007] The winding body includes:

[0008] The wire placement reel is fixed on a fixed platform. Its upper end is provided with radially distributed wire placement slots at circumferential intervals, which are consistent with the number of wire placement slots of the excitation winding. Each wire placement slot can vertically place a W-shaped enameled wire.

[0009] The wire pushing component, located inside the wire placement groove, is used to push the enameled wire toward the center of the wire placement reel;

[0010] The rotating ring is rotatably mounted outside the wire-holding reel;

[0011] The linkage component is located between the rotating ring and the wire pushing component. As the rotating ring rotates in both directions, the wire pushing component can reciprocate radially along the wire placing disc.

[0012] The first driving component is used to drive the rotating ring to achieve reciprocating motion in both directions;

[0013] The rotor clamping drive component includes:

[0014] The rotating body is rotatably positioned at the center of the wire-laying disk, and the lower end of the rotor can be partially inserted into the rotating body and rotate synchronously with it.

[0015] The top pressing component is lifted and positioned above the wire placing plate. As the top pressing component rises, it can detach from the rotor; as the top pressing component descends, it can press the rotor onto the rotating body and rotate synchronously with the rotating body.

[0016] The second driving component is used to drive the rotating body to rotate back and forth by a certain angle.

[0017] The above scheme includes a winding body and a rotor clamping drive component. The rotating body in the rotor clamping drive component is located at the center of the winding body's wire-holding disk. After the rotor is inserted into the rotating body, the top pressure component descends to press the rotor, ensuring that the rotor rotates synchronously with the rotating head. The second drive component drives the rotating body to rotate the rotor back and forth by a preset angle. The wire-holding disk of the winding body has the same number of wire slots as the excitation winding slots on the rotor's insulating iron chip. Each wire slot contains a pre-bent "W"-shaped enameled wire. A wire-pushing component within the wire slot, driven by the first drive component and linked by a linkage component, moves radially back and forth along the wire-holding disk. When the wire-pushing component approaches the rotating body, it delivers a portion of the enameled wire to the rotor. The enameled wire is pre-set in a "W" shape to facilitate the pushing of the wire pusher. The pusher can only push the vertical part of the enameled wire, and the height of the vertical part is exactly the height of the excitation winding slot. The horizontal part of the enameled wire can automatically wind around the upper and lower ends of the insulating iron chip as the rotor rotates, thus achieving automatic winding. Using the above-mentioned tooling, N enameled wires can be wound synchronously on the rotor insulating iron chip quickly. The winding of one rotor can be completed in just tens of seconds. The feeding of the enameled wire and the loading and unloading of the rotor can be achieved manually or automatically. Even with manual loading and unloading, 30-60 can be completed per hour, which is significantly more efficient than the existing technology that completes 40 in 8 hours.

[0018] Preferably, the wire placement slot is fan-shaped with its small-diameter end facing the rotating body. The width of the small-diameter end of the wire placement slot is less than or equal to the width of the excitation winding slot. The width of the wire pushing component is the same as that of the small-diameter end of the wire placement slot. A slot corresponding to and the same size as the small-diameter end of the wire placement slot is recessed at the large-diameter end of the wire placement slot. The end of the wire pushing component away from the small-diameter end of the wire placement slot is inserted into the slot.

[0019] The advantage of using the above scheme, with the wire placement slot set in a fan shape, is that it provides sufficient space for the wire pushing component to retract, so that the wire pushing component will not interfere with the enameled wire when retracting. The small-diameter end of the wire placement slot corresponds to the slot and has the same diameter to guide the wire pushing component, driving the wire pushing component to reciprocate only along the radial direction of the wire placement disk within the wire placement slot, ensuring the wire pushing accuracy of the wire pushing component. The small-diameter port diameter of the wire placement slot is less than or equal to that of the excitation winding slot, which can ensure that the enameled wire can be accurately pushed into the excitation winding slot as the wire pushing component pushes.

[0020] Preferably, the linkage component includes a first hinge arm and a second hinge arm that are hinged together. The end of the first hinge arm away from the second hinge arm is hinged to the inner wall of the rotating ring. The end of the second hinge arm away from the first hinge arm is connected to the end of the wire pushing component away from the rotating body. A receiving groove is recessed in the outer ring wall of the wire placing plate to accommodate the second hinge arm and to guide the movement of the second hinge arm. The bottom of the receiving groove is connected to the slot.

[0021] Using the above scheme, after the second articulated arm is connected to the wire pushing component, it can only slide within the receiving groove. The first articulated arm will shift its position as the rotating ring rotates, which will drive the second articulated arm to move. Since all the first articulated arms are hinged to the rotating ring, the turntable only needs to rotate in both directions to drive all the second articulated arms to move synchronously and keep the travel distance consistent. This will drive the wire pushing component to move forward or backward synchronously and keep the travel distance consistent, thereby ensuring the synchronicity and accuracy of the enameled wire winding on the insulated iron chip.

[0022] Preferably, the pusher component is detachably connected to the second hinge arm. A limiting block is provided at one end of the pusher component near the second hinge arm. A matching groove is provided on the second hinge arm, which allows the limiting block to be inserted perpendicular to its movement direction and to be stopped and disengaged in its movement direction. A through groove is provided on the side of the receiving groove near the opening of the wire placement groove, which allows the pusher component to be pulled out.

[0023] With the above solution, the push-wire component and the second hinge arm are plugged in and connected. The through slot allows the push-wire component to be installed or removed directly without disassembling the linkage component, increasing the convenience of the push-wire component's installation and removal.

[0024] Preferably, a keyway is provided in the rotating body, and the rotor is keyed to the keyway.

[0025] Preferably, the first driving component includes an arc-shaped rack distributed circumferentially on the outer wall of the rotating ring, a meshing member that meshes with the arc-shaped rack, and a driving member that drives the meshing member to rotate the rotating ring.

[0026] Using the above scheme, the driving component drives the meshing component to move, thereby driving the reciprocating rotation of the rotating ring meshing with the meshing component, which in turn drives the rotation of the first hinge arm hinged to the rotating ring, which in turn drives the movement of the second hinge arm hinged to the first hinge arm in the receiving groove, and finally realizes the reciprocating movement of the pusher component connected to the second hinge arm in the wire placement groove.

[0027] Preferably, the meshing component is a straight rack, and the driving component is a first cylinder fixed on a fixed platform, with the piston rod of the first cylinder fixedly connected to the side of the straight rack away from the curved rack.

[0028] Using the above scheme, the linear reciprocating motion of the rack can drive the rotating ring meshing with it to rotate in both directions, while the extension and retraction of the cylinder piston rod can drive the linear reciprocating motion of the rack.

[0029] Preferably, the meshing component is a meshing gear that rotates horizontally on a fixed platform, and the driving component is a first motor fixed on the fixed platform, with the motor shaft of the first motor being coaxially fixed with the meshing gear.

[0030] Using the above scheme, the rotation of the meshing gear can drive the rotating ring meshing with it to rotate in both directions, and the forward and reverse rotation of the first motor shaft can drive the meshing gear connected to it to rotate in both directions.

[0031] Preferably, the top pressing component is a second cylinder, with the piston rod of the second cylinder arranged vertically downward and a rotating top block rotatably mounted at its lower end.

[0032] By adopting the above scheme, the extension and retraction of the piston rod of the second cylinder can make the rotating top block press against or move away from the rotor. Since the rotating top block is in rotational cooperation with the piston rod, when the rotor rotates, the rotating top block can rotate accordingly, and the piston rod of the second cylinder can remain stationary.

[0033] Preferably, the second driving component includes a second motor fixed on a fixed platform, a driven gear coaxially fixed to the outer wall of the rotating body, and a driving gear meshing with the driven gear coaxially fixed to the motor shaft of the second motor.

[0034] Using the above scheme, the drive gear of the second motor can drive the driven gear meshing with it to rotate, thereby driving the rotation of the rotating body. By simply switching the direction of the second motor, the direction of rotation of the rotating body can be switched, thereby switching the direction of the rotor, and finally switching the direction of rotation of the insulating iron chip.

[0035] This invention, by employing the above technical solution, has significant technical effects: It comprises a winding body and a rotor clamping drive component. The rotating body in the rotor clamping drive component is located at the center of the winding body's wire-holding disk. When the rotor is inserted onto the rotating body, the top pressure component descends to press the rotor, ensuring that the rotor can rotate synchronously with the rotating head. The second drive component drives the rotating body to rotate the rotor back and forth by a preset angle. The wire-holding disk of the winding body has the same number of wire slots as the excitation winding slots on the rotor's insulating iron chip. Each wire slot holds a pre-bent "W"-shaped enameled wire. A wire-pushing component within the wire slot, driven by the first drive component and linked by a linkage component, moves radially back and forth along the wire-holding disk. When the wire-pushing component approaches the rotating body, it pushes the enameled wire... The enameled wire is fed to the rotor. The reason why the enameled wire is pre-set in a "W" shape is to facilitate the pushing of the wire pushing component. The pushing component can only push the vertical part of the enameled wire. The height of the vertical part is exactly the height of the excitation winding slot. The horizontal part of the enameled wire can automatically wind around the upper and lower ends of the insulating iron chip as the rotor rotates, thereby realizing automatic winding. Using the above-mentioned tooling, N enameled wires can be wound synchronously on the rotor insulating iron chip quickly. The winding of one rotor can be completed in just tens of seconds. The feeding of the enameled wire and the loading and unloading of the rotor can be realized by manual or automatic loading and unloading equipment. Even with manual loading and unloading, 30-60 can be completed per hour, which is significantly more efficient than the existing technology that completes 40 in 8 hours. Attached Figure Description

[0049] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0050] Example

[0051] An automatic winding fixture for starter rotors, as described in the following figure. Figures 1-14 As shown, it includes a fixed platform 19 and a winding body and a rotor clamping drive component disposed on the fixed platform 19.

[0052] The winding body includes a wire placement part 1 and a rotating part 2 rotatably disposed outside the wire placement part.

[0053] Reference to line setting part 1 Figure 13 As shown, the device includes a wire-holding reel 102 and a first end cap 101 fixed to the upper and lower end faces of the wire-holding reel 102 with screws. The upper end of the wire-holding reel 102 has radially distributed wire-holding grooves 1021 spaced at circumferential intervals. A central hole is provided at the center of the wire-holding reel 102. Figures 7-9 As shown, the number of wire slots 1021 is the same as the number of excitation winding slots 161 on the insulated iron chip 16. Each wire slot 1021 can vertically hold a W-shaped enameled wire 12. Figure 6 As shown, the first end cap 101 on the side near the wire placement groove 1021 can expose the entire wire placement groove 1021 to facilitate the placement of the enameled wire 12. A wire pushing component 13 is provided in the wire placement groove 1021. The wire placement groove 1021 is fan-shaped, with the small-diameter end of the wire placement groove 1021 facing the central hole and penetrating through the central hole. The width of the small-diameter end of the wire placement groove 1021 is the same as that of the wire pushing component 13. The reason why the wire placement groove 1021 is fan-shaped is to prevent the wire pushing component 13 from interfering with the enameled wire 12 when it retracts, thus avoiding damage to the enamel layer of the enameled wire 12. In order to ensure that the wire pushing component 13 always reciprocates along the radial direction of the wire placement disc 102, a slot 1022 corresponding to and the same size as the small-diameter end of the wire placement groove 1021 is recessed at the large-diameter end of the wire placement groove 1021. The end of the wire pushing component 13 away from the small-diameter end of the wire placement groove 1021 is inserted into the slot 1022.

[0054] Rotating part 2 (reference) Figure 14 As shown, it includes a rotating ring 202 located outside the cable tray 102 and second end caps 201 that are detachably mounted on the upper and lower ends of the rotating ring 202 by screws, combined with Figure 7 or Figure 10 As shown, the rotating ring 202 is fitted with the wire placement disc 102 at a distance. The second end cover 201 is sleeved outside the first end cover 101. The second end cover 201 located below is rotatably fitted with the first end cover 101 through the bearing 18, thereby realizing the rotatable fit between the rotating part 2 and the wire placement part 1.

[0055] A linkage component is provided between the rotating ring 202 and the wire placement plate 102, which drives all the wire pushing components 13 to move forward or backward synchronously as the rotating ring 202 rotates. (Refer to...) Figure 7 and Figure 8As shown, the linkage component includes a first hinge arm 14 and a second hinge arm 15 hinged together. The first hinge arm 14 is housed within the distance between the rotating ring 202 and the wire placement groove 1021. The end of the first hinge arm 14 away from the second hinge arm 15 is hinged to the rotating ring 202 or the second end cap 201. In this embodiment, both ends of the first hinge arm 14 are rotatably connected to the two second end caps 201 respectively. As the rotating ring 202 rotates, the first hinge arm 14 can swing back and forth. The end of the second hinge arm 15 away from the first hinge arm 14 is connected to the end of the wire pushing component 13 away from the rotating body 8. The outer ring wall of the wire placement disk 102 has a recess for accommodating the second hinge arm 15 and for guiding the second hinge arm 15. The movable receiving groove 1023 is connected to the slot 1022 at its bottom. After the second hinge arm 15 is connected to the wire pushing component 13, it can only slide within the receiving groove 1023. The first hinge arm 14 will move as the rotating ring 202 rotates and shifts its position, which will drive the second hinge arm 15 to move. Since all the first hinge arms 14 are hinged to the rotating ring 202, the turntable can be rotated in both directions to drive all the second hinge arms 15 to move synchronously and keep the running stroke consistent. This will drive the wire pushing component 13 to move forward or backward synchronously and keep the running stroke consistent, thereby ensuring the synchronicity and accuracy of the winding of the enameled wire 12 on the insulated iron chip 16.

[0056] To facilitate the assembly and disassembly of the wire pusher component 13, the wire pusher component 13 is detachably connected to the second hinge arm 15. See [reference needed]. Figure 8 and Figure 12 As shown, a limiting plug 131 is provided at one end of the pusher component 13 near the second hinge arm 15. A mating groove 151 is provided on the second hinge arm 15 for the limiting plug 131 to be inserted in a direction perpendicular to its movement direction and for the limiting plug 131 to be dislodged in its movement direction. A through groove 1024 is provided on the side of the receiving groove 1023 near the opening of the wire placement groove 1021 for the pusher component 13 to be pulled out.

[0057] The rotation of the rotating ring 202 is controlled by the first driving component, combined with Figure 3 and Figure 6 As shown, the first driving component includes an arc-shaped rack 3 circumferentially distributed on the outer wall of the rotating ring 202. A meshing component that meshes with the arc-shaped rack 3 is provided on the fixed platform 19. The meshing component is a spur rack 4 or a meshing gear. In this embodiment, a spur rack 4 is used. The spur rack 4 wire slides on the fixed platform 19. The spur rack 4 meshes with the arc-shaped rack 3. The reciprocating movement of the spur rack 4 drives the rotating ring 202 to rotate in both directions. The movement of the spur rack 4 is controlled by a first cylinder 5. The cylinder body of the first cylinder 5 is fixed on the fixed platform 19. The piston rod end of the first cylinder 5 is fixedly connected to the middle part of the side of the spur rack 4 away from the arc-shaped rack 3.

[0058] The rotor clamping drive component includes a rotating body 8, which is combined with... Figure 1 and Figure 11 As shown, the rotating body 8 is rotatably disposed at the center hole of the wire groove 1021. The upper end of the rotating body 8 is provided with a keyway 801 into which the lower end of the rotor can be inserted. In this embodiment, the keyway 801 is a spline groove 801. The rotor and the spline groove 801 rotate synchronously through a spline engagement. A pressing member is vertically mounted above the rotating body 8. (See Figure 1) Figure 3 As shown, the pressing component can detach from the rotor after rising, facilitating the unloading of the rotor; after descending, the pressing component presses against the rotor's shaft to ensure it rotates synchronously with the rotating body 8. In this embodiment, the pressing component is a second cylinder 6. The cylinder body of the second cylinder 6 is fixed above the fixed platform 19. The piston rod of the second cylinder 6 is vertically downward and has a rotating top block 7 rotatably mounted at its end. The rotating top block 7 can press against the rotating shaft while rotating with the shaft, avoiding adverse effects on the second cylinder 6. The rotation of the rotating body 8 is controlled by the second drive component, see [link to relevant documentation]. Figures 4-5 As shown, the second drive component includes a second motor 10 fixed to the lower end face of the fixed platform 19, the lower end of the rotating body 8 extends to the lower part of the fixed platform, a driven gear 9 is coaxially fixed on the outer wall of the rotating body 8 below the fixed platform, and a drive gear 11 that meshes with the driven gear 9 is coaxially fixed on the motor shaft of the second motor 10. As the rotation direction of the motor shaft of the second motor 10 is switched, the rotation direction of the rotating body 8 can be switched, and finally the rotation direction of the rotor can be switched.

[0059] Before using this fixture to wind the motor rotor, the enameled wire 12 needs to be cut into equal-length segments, and then the segments need to be shaped into a flat "W" shape. See [link to relevant documentation]. Figure 2 As shown, the reason for shaping it into a "W" shape is to facilitate the pushing of the wire pushing component 13. The wire pushing component 13 can only push the vertical part of the enameled wire 12. The height of the vertical part is exactly the height of the excitation winding slot 161. The horizontal part of the enameled wire 12 can automatically wind around the upper and lower ends of the insulating iron chip 16 as the rotor rotates, thereby realizing the automatic winding of the rotor.

[0060] The rotor winding steps are as follows:

[0061] 1. Using manual labor or feeding equipment, place the enameled wires 12 one by one into the wire placement trough 1021;

[0062] 2. The rotor is inserted into the rotating body 8 by manual labor or feeding equipment to achieve keying. At this time, the magnetic winding slots on the rotor and the placement slots 1021 are in a one-to-one correspondence.

[0063] 3. The piston rod of the second cylinder 6 extends out, and the rotating top block 7 presses against the upper end of the rotor;

[0064] 4. The electromagnetic pneumatic control valve of the first cylinder 5 is switched, driving the rotating ring 202 to rotate counterclockwise by a certain angle, and the wire pushing component 13 directly pushes the first vertical section of the enameled wire 12 into the corresponding excitation winding slot 161.

[0065] 5. The electromagnetic pneumatic control valve of the first cylinder 5 switches, driving the rotating ring 202 to rotate clockwise by the same angle, and the wire pushing component 13 retracts, leaving space for the movement of the enameled wire 12.

[0066] 6. The second motor 10 rotates at a certain angle, so that the first horizontal section of the enameled wire 12 is automatically wound around the end of the insulated iron chip 16. At the same time, an adjacent excitation winding slot 161 corresponds to the current placement slot 1021.

[0067] 7. The electromagnetic pneumatic control valve of the first cylinder 5 is switched, driving the rotating ring 202 to rotate counterclockwise by a certain angle, and the wire pushing component 13 pushes the second vertical section of the enameled wire 12 into the current excitation winding slot 161.

[0068] 8. Repeat step 5;

[0069] 9. The second motor 10 reverses the same angle, so that the second horizontal section of the enameled wire 12 is automatically wound around the other end of the insulating iron chip 16. At the same time, the excitation winding slot 161 of step 4 is reset to the current slot 1021.

[0070] 10. Repeat steps 4-8 once;

[0071] 11. The electromagnetic control valve of the second cylinder 6 is switched, and the piston rod of the second cylinder 6 rises and disengages from the rotor;

[0072] 12. Remove the motor manually or using a material unloading device;

[0073] The above steps realize the automatic winding of a rotor. After winding, both ends of the enameled wire 12 are set upward and located in the two adjacent excitation winding slots 161. In the subsequent process, the two ends of the enameled wire 12 will be welded to the commutator segments 171 (copper sheets) on the commutator 17.
