[0002] A winding machine is a device that winds a linear object onto a specific workpiece, and is usually used for winding copper wire. In the field of motor manufacturing, an internal winding machine is usually used to wind the stator of a brushless motor. The internal winding machine is controlled by a servo drive, and the needle bar thread nozzle drives the copper wire up and down, and the mold rotates left and right to neatly wind the copper wire into the slot of the brushless motor stator. In the actual production process, the stator is fixed to the winding machine through a mold. A mold can usually only adapt to one model of stator. If stators of other sizes and shapes need to be produced, a corresponding new mold must be made. Making different molds increases production costs and time costs, and the mold replacement procedure is cumbersome, which reduces production efficiency. Utility Model Content

[0022] Reference Figures 1 to 3 .
[0023] Embodiment 1 further describes a winding machine for motor manufacturing proposed by the utility model.
[0024] A winding machine for motor manufacturing comprises a rotating drum 1, a side wall of which is provided with a first through hole 2;
[0025] The apparatus further comprises a limiting rod 3, which passes through the side wall of the rotating cylinder 1 through the first through hole 2, and is threadedly connected with a first nut 4 and a second nut 5, wherein the first nut 4 is located on the outside of the rotating cylinder 1, and the second nut 5 is located on the inside of the rotating cylinder 1;
[0026] The end of the limiting rod 3 is fixedly connected with an L-shaped clamping plate 6, which is located inside the rotating cylinder 1. The L-shaped clamping plate 6 is elastically connected with a limiting plate 7, and the surfaces of the L-shaped clamping plate 6 and the limiting plate 7 are fixedly connected with an anti-slip pad 8.
[0027] The staff manually pushes and pulls the limit rod 3 to move the limit rod 3 in the radial direction of the rotating cylinder 1. Since the limit rod 3 is fixedly connected to the L-shaped clamping plate 6, the limit rod 3 drives the L-shaped clamping plate 6 to move radially during the movement. When the distance between the relative L-shaped clamping plates 6 is suitable for the stator size and the distance between each L-shaped clamping plate 6 and the rotating cylinder 1 is the same, the first nut 4 and the second nut 5 are manually rotated to make the first nut 4 and the second nut 5 fit tightly against the side wall of the rotating cylinder 1. Since the limit rod 3 is threadedly connected to the first nut 4 and the second nut 5 at the same time, the limit rod 3 is locked on the side wall of the rotating cylinder 1 through the first through hole 2, so the distance between the L-shaped clamping plate 6 and the rotating cylinder 1 is fixed.
[0028] The staff manually moves the limiting plate 7 in the direction away from the L-shaped clamping plate 6. Since the surfaces of the L-shaped clamping plate 6 and the limiting plate 7 are fixedly connected with the anti-skid pads 8, the limiting plate 7 drives the anti-skid pads 8 to move during the movement, so that the distance between the anti-skid pads 8 on both sides becomes larger, and the stator is manually placed between the anti-skid pads 8 on both sides and tightly fits the L-shaped clamping plate 6. The limiting plate 7 is released. Since the limiting plate 7 and the L-shaped clamping plate 6 are elastically connected, the limiting plate 7 is close to the L-shaped clamping plate 6 under the elastic resetting action. Therefore, the limiting plate 7 and the L-shaped clamping plate 6 lock the stator through the anti-skid pads 8. Since the anti-skid pads 8 are made of rubber material, the friction between the stator and the contact surface is increased, thereby enhancing the stability of the stator.
[0029] Since the limit rod 3 drives the L-shaped clamping plate 6 to move in the radial direction, it can lock stators of different diameters. At the same time, since the limit plate 7 drives the anti-slip pad 8 to move in the vertical direction, it can lock stators of different heights. Therefore, when replacing the stator, it is only necessary to adjust the limit rod 3 and the limit plate 7, and there is no need to remake the stator mold, so that the winding machine is suitable for stators of any size within the adjustment range, saving production costs, simplifying production procedures, and improving production efficiency.
[0030] A flexible pad 9 is fixedly connected to the inner wall of the rotating cylinder 1, and a second through hole 10 is opened on the side wall of the flexible pad 9. The second through hole 10 has the same size as the first through hole 2 and corresponds in position. The limiting rod 3 passes through the first through hole 2 and the second through hole 10 while penetrating the rotating cylinder 1 and the flexible pad 9. When the staff manually tightens the second nut 5, the second nut 5 fits tightly against the flexible pad 9. Since the flexible pad 9 is made of rubber material, the friction between the second nut 5 and the contact surface is increased, thereby enhancing the stability of the limiting rod 3.
[0031] A spring group 11 is fixedly connected between the L-shaped clamping plate 6 and the limit plate 7. The staff manually moves the limit plate 7 in the direction away from the L-shaped clamping plate 6. During the movement, the limit plate 7 stretches the spring group 11 and drives the anti-skid pad 8 to move, so that the distance between the anti-skid pads 8 on both sides becomes larger. The stator is manually placed between the anti-skid pads 8 on both sides and fits tightly against the L-shaped clamping plate 6. The limit plate 7 is released, and the spring group 11 elastically resets, driving the limit plate 7 close to the L-shaped clamping plate 6. Therefore, the limit plate 7 and the L-shaped clamping plate 6 lock the stator through the anti-skid pad 8.
[0032] A winding rod 12 is fixedly connected to the end surface of the rotating drum 1 .
[0033] The end surface of the rotating cylinder 1 is movably connected with a wire lifting plate 13, and a wire lifting hole 14 is opened on the surface of the wire lifting plate 13. The number of the wire lifting holes 14 is the same as that of the winding rod 12 and the positions are corresponding. The winding rod 12 passes through the lifting hole 14. During the winding process, the winding machine needs to wind part of the copper wire around the side wall of the winding rod 12 to position and tighten the copper wire. After the winding is completed, the staff manually picks up the wire lifting plate 13. During the vertical upward movement, the wire lifting plate 13 drives the copper wire on the side wall of the winding rod 12 to move vertically upward until the copper wire is completely separated from the winding rod 12, thereby avoiding pulling the copper wire on the winding rod 12 during the removal of the stator, reducing damage to the surface of the copper wire, and avoiding the pulling process that causes uneven tension in the already wound coil.
[0034] A washer 15 is fixedly connected to the inner wall of the wire lifting hole 14, and the washer 15 matches the size of the winding rod 12. The staff manually picks up the wire lifting plate 13. Since the washer 15 is fixedly connected to the inner wall of the wire withdrawal hole 14 and the washer 15 is in contact with the side wall of the winding rod 12, the wire lifting plate 13 drives the washer 15 and the copper wire on the side wall of the winding rod 12 to move vertically upward during the vertical upward movement until the copper wire is completely separated from the winding rod 12. Since the washer 15 is made of flexible material, the wear of the wire withdrawal hole 14 and the winding rod 12 is reduced.
[0035] Working principle: the staff manually pushes and pulls the limit rod 3 to move the limit rod 3 in the radial direction of the rotating cylinder 1. Since the limit rod 3 is fixedly connected to the L-shaped clamping plate 6, the limit rod 3 drives the L-shaped clamping plate 6 to move radially during the movement. When the distance between the relative L-shaped clamping plates 6 is suitable for the stator size, and the distance of each L-shaped clamping plate 6 relative to the rotating cylinder 1 is the same, the first nut 4 and the second nut 5 are manually rotated to make the first nut 4 fit tightly with the rotating cylinder 1, and the second nut 5 fit tightly with the flexible pad 9. Since the limit rod 3 is threadedly connected to the first nut 4 and the second nut 5 at the same time, the limit rod 3 is locked on the side wall of the rotating cylinder 1 through the first through hole 2 and the second through hole 10. Therefore, the distance of the L-shaped clamping plate 6 relative to the rotating cylinder 1 is fixed. Since the flexible pad 9 is made of rubber material, the friction between the second nut 5 and the contact surface is increased, thereby enhancing the stability of the limit rod 3.
[0036] The staff manually moves the limit plate 7 away from the L-shaped clamping plate 6. During the movement, the limit plate 7 stretches the spring group 11 and drives the anti-skid pad 8 to move, so that the distance between the anti-skid pads 8 on both sides becomes larger. The stator is manually placed between the anti-skid pads 8 on both sides and fits tightly against the L-shaped clamping plate 6. The limit plate 7 is released, and the spring group 11 elastically resets, driving the limit plate 7 close to the L-shaped clamping plate 6. Therefore, the limit plate 7 and the L-shaped clamping plate 6 lock the stator through the anti-skid pad 8.
[0037] Since the limit rod 3 drives the L-shaped clamping plate 6 to move in the radial direction, it can lock stators of different diameters. At the same time, since the limit plate 7 drives the anti-slip pad 8 to move in the vertical direction, it can lock stators of different heights. Therefore, when replacing the stator, it is only necessary to adjust the limit rod 3 and the limit plate 7, and there is no need to remake the stator mold, so that the winding machine is suitable for stators of any size within the adjustment range, saving production costs, simplifying production procedures, and improving production efficiency.
[0038] During the winding process, the winding machine needs to wind part of the copper wire around the side wall of the winding rod 12 to position and tighten the copper wire. Before the winding starts, the staff manually places the lifting plate 13 on the end face of the rotating cylinder 1. After the winding is completed, the staff manually lifts the lifting plate 13 vertically upward to separate the lifting plate 13 from the rotating cylinder 1. During the vertical upward movement, the lifting plate 13 drives the washer 15 and the copper wire on the side wall of the winding rod 12 to move vertically upward until the copper wire is completely separated from the winding rod 12, avoiding pulling the copper wire on the winding rod 12 during the removal of the stator, reducing damage to the surface of the copper wire, and avoiding the pulling process that causes uneven tension in the already wound coil. Since the washer 15 is made of flexible material, the wear of the withdrawal hole 14 and the winding rod 12 is reduced.
[0039] Embodiment 2
[0040] The following technical features are added on the basis of the first embodiment:
[0041] A T-shaped plate 16 is fixedly connected to the outer side wall of the thread lifting plate 13 .
[0042] A copper bead 17 is fixedly connected to the surface of the T-shaped plate 16, and a slot 18 is provided on the outer side wall of the rotating cylinder 1. The slot 18 corresponds to the position of the copper bead 17 and the size matches. Before winding begins, the staff manually places the wire lifting plate 13 on the end face of the rotating cylinder 1 through the T-shaped plate 16, and presses the wire lifting plate 13 at the same time. Since the copper bead 17 is fixedly connected to the T-shaped plate 16, the slot 18 corresponds to the position of the copper bead 17 and the size matches, the T-shaped plate 16 drives the copper bead 17 to fit into the slot 18. Since the slot 18 is provided on the outer side wall of the rotating cylinder 1, the T-shaped plate 16 fastens the wire lifting plate 13 to the rotating cylinder 1 to prevent the wire lifting plate 13 from falling off the winding rod 12 during rotation.
[0043] After the winding is completed, the staff manually lifts the lifting plate 13 vertically upward through the T-shaped plate 16, and the T-shaped plate 16 drives the copper bead 17 to disengage from the card slot 18, thereby separating the lifting plate 13 from the rotating cylinder 1, making it easier to remove the lifting plate 13 from the winding rod 12.
[0044] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
