[0027] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0028] This application discloses a wire feeding reel positioning device for enameled wire. (Refer to...) Figures 1-5 A wire feeding reel positioning device for enameled wire includes a base 1, a main shaft 2 rotatably connected to the outer wall of the base 1, a rotating disk 3 fixedly connected to the outer wall of the main shaft 2, a gear disk 5 rotatably connected to the outer wall of the main shaft 2 through a bearing 4, the rotating disk 3 being located between the gear disk 5 and the base 1, and an adjustment mechanism being installed on the outer walls of the rotating disk 3 and the gear disk 5.

[0029] The adjustment mechanism includes multiple positioning pins 9 installed on the outer wall of the rotating disk 3. Multiple arc-shaped grooves 6 are opened on the outer wall of the toothed disk 5. The multiple arc-shaped grooves 6 correspond to the multiple positioning pins 9, and the positioning pins 9 are slidably connected to the inner wall of the arc-shaped grooves 6.

[0030] Multiple inner support plates 13 are provided at the end of the main shaft 2 away from the base 1. The multiple inner support plates 13 are evenly distributed in a circular array at equal intervals around the end of the main shaft 2. An inner support mechanism that drives the multiple inner support plates 13 to move synchronously is installed on the outer wall of the main shaft 2.

[0031] The adjustment mechanism also includes a self-locking motor 11 fixedly installed on the outer wall of the rotating disk 3 on the side opposite to the gear disk 5. The output shaft of the self-locking motor 11 passes through the rotating disk 3 and is fixedly connected to a first gear 10. The first gear 10 meshes with the edge of the gear disk 5. The self-locking motor 11 is connected to an external power source through a wire.

[0032] Multiple guide rails 7 are fixedly connected to the outer wall of the rotating disk 3 facing the toothed disk 5. Slider 8 is slidably connected to the outer wall of the guide rail 7. Multiple positioning posts 9 are welded to the outer wall of the multiple slider 8. The sliding connection between the guide rail 7 and the slider 8 is used to limit the movement direction of the positioning posts 9, so that the positioning posts 9 always move linearly.

[0033] The internal support mechanism includes a movable cylinder 12 that is slidably connected to the outer wall of the end of the main shaft 2. Multiple connecting rods 14 are rotatably connected to the outer wall of the movable cylinder 12, and multiple connecting rods 15 are rotatably connected to the outer wall of the main shaft 2. The connecting rods 14 and 15 are arranged crosswise, and their top ends correspond to the internal support plate 13. The middle sections of the two crosswise connecting rods 14 and 15 are rotatably connected to each other.

[0034] The end of connecting rod 14 away from the movable cylinder 12 is rotatably connected to the outer wall of the inner support plate 13. The outer walls of multiple inner support plates 13 are fixedly connected to movable jaw frames 16. The end of connecting rod 2 away from the main shaft 2 is movably connected to the inner wall of the movable jaw frame 16.

[0035] The internal support mechanism also includes an electric telescopic rod 17 fixedly installed on the inner wall of the main shaft 2, and the output end of the electric telescopic rod 17 is fixedly connected to the inner wall of the end of the movable cylinder 12.

[0036] Multiple limiting blocks 19 are fixedly connected to the outer wall of the end of the main shaft 2 away from the base 1. Multiple limiting grooves 18 are opened on the outer wall of the movable cylinder 12. The limiting blocks 19 are slidably connected to the inner wall of the limiting grooves 18. When the movable cylinder 12 slides at the end of the main shaft 2, the limiting blocks 19 at the end of the main shaft 2 will slide on the inner wall of the limiting grooves 18, which will play a limiting role, so that the movable cylinder 12 always slides linearly at the end of the main shaft 2 and will not rotate.

[0037] The outer wall of the base 1 is equipped with a drive assembly for driving the rotating disk 3 to rotate. The drive assembly includes a servo motor 22 fixedly installed on the outer wall of the base 1. The output shaft of the servo motor 22 passes through the base 1 and is fixedly connected to a second gear 21. The servo motor 22 can be fixed to the base 1 by multiple screws and is connected to an external power source through wires.

[0038] A linkage gear 20 is fixedly connected to the outer wall of the rotating disk 3 facing the base 1, and the linkage gear 20 meshes with the second gear 21.

[0039] The implementation principle of the wire feeding reel positioning device of this application embodiment is as follows: In use, multiple positioning holes on the wire feeding reel are inserted into multiple positioning posts 9, and their centers are inserted into the main shaft 2. When multiple positioning posts 9 are inserted into multiple positioning holes on the wire feeding reel, the wire feeding reel can be initially positioned.

[0040] Next, the electric telescopic rod 17 is activated through the inner support mechanism on the outer wall of the main shaft 2. The output end of the electric telescopic rod 17 retracts, which drives the movable cylinder 12 to slide toward the main shaft 2. At this time, the ends of multiple connecting rods 15 on the outer wall of the main shaft 2 and the ends of multiple connecting rods 14 on the outer wall of the movable cylinder 12 approach each other. Therefore, connecting rods 14 and 15 will rotate around the middle section. The tops of connecting rods 14 and 15 will push the inner support plate 13 outward. The multiple inner support plates 13 will expand synchronously, so that the multiple inner support plates 13 abut against the inner wall of the center of the pay-off reel, thereby achieving inner support fixation. A rubber anti-slip layer (not shown in the figure) can also be set on the outer wall of the multiple inner support plates 13 to increase the friction with the pay-off reel and improve the fixation stability of the pay-off reel.

[0041] When positioning reels of different sizes, the self-locking motor 11 can be started through the adjustment mechanism. The output shaft of the self-locking motor 11 drives the first gear 10 to rotate, which in turn drives the gear disk 5 meshing with it to rotate. The gear disk 5 can rotate on the outer wall of the main shaft 2 through the bearing 4, so that multiple arc-shaped grooves 6 rotate around the axis of the gear disk 5. The arc-shaped grooves 6 can drive the positioning pins 9 located inside them to slide. The multiple positioning pins 9 can move synchronously by sliding the guide rail 7 and the slider 8, so that the multiple positioning pins 9 can be adapted to the positioning holes at different positions on the reels of different sizes, thereby achieving precise positioning of reels of different specifications.

[0042] After the wire feeding reel is positioned, the servo motor 22 is started by the drive component. The output shaft of the servo motor 22 drives the second gear 21 to rotate. The second gear 21 drives the linkage gear 20 meshing with it to rotate. The linkage gear 20 then drives the rotating disk 3 to rotate. The rotating disk 3 then drives the wire feeding reel to rotate through multiple positioning pins 9 and the internal support mechanism, thereby performing the wire feeding operation on the enameled wire.

[0043] It is worth noting that the spindle 2 has a hollow structure inside, so the power connection cable of the electric telescopic rod 17 can pass through the spindle 2 to connect to an external power source. To prevent the power connection cable of the electric telescopic rod 17 from getting tangled when the spindle 2 rotates, a slip ring (not shown in the figure) can be used. The power cable of the external power source is connected to the fixed end of the slip ring, while the rotating end of the slip ring is connected to the electric telescopic rod 17 and rotates synchronously. This prevents the cable from getting tangled as the spindle 2 rotates.
