[0003] During the existing inductance winding, the coil is first placed between multiple groups of limiting rollers and fixed by the limiting rollers, and then winding is carried out. For example, an inductance winding disclosed in Chinese Patent CN205789497U uses this technical solution. After the winding is completed, after the enameled wire is cut off, the multiple groups of limiting rollers are loosened, and then the coil-wound coil is taken out upward from between the multiple groups of limiting rollers. This method requires manual unloading or grasping by a manipulator. The fixing mechanism lacks the function of automatic blanking and requires manual or manipulator assistance, and the function is not perfect enough. Summary of the Utility Model

Specific embodiments

[0019] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: a fixing mechanism for inductance winding, including a bottom plate 1, a mounting plate 2 and a fixed plate 7 are fixedly connected to the bottom plate 1, and the fixed plate 7 is located in front of the mounting plate 2 and is spaced apart from each other;

[0021] The upper part of the front side of the fixed plate 7 is rotatably provided with a first limiting roller 8, and two second limiting rollers 17 that can move vertically and are spaced apart from each other are provided at the bottom of the fixed plate 7, and the two second limiting rollers 17 are respectively located on both sides of the bottom of the first limiting roller 8.

[0022] The two second limiting rollers 17 can be synchronously lifted and lowered to adjust the height, cooperate with the first limiting roller 8 to clamp and fix the electric coil, and then wind the coil through a winding machine.

[0023] The first limiting roller 8 is a driving roller, and the two second limiting rollers 17 are driven rollers. After the three limiting rollers clamp the electric coil, the first limiting roller 8 rotates, thereby driving the electric coil to rotate, and the two second limiting rollers 17 rotate drivenly, so that the electric coil can rotate continuously and slowly to change the winding position, so as to wind the electric coil orderly.

[0024] The two second limiting rollers 17 are respectively located at both ends of the fixed plate 7, and the two second limiting rollers 17 do not interfere with each other.

[0025] A first rack 20 is fixedly connected between the front side of the mounting disc 2 and the rear side of the fixed disc 7. A positioning rod 9 capable of moving horizontally is arranged on the front side surface of the mounting disc 2. The positioning rod 9 penetrates through the fixed disc 7. A first rotating shaft 5 is rotatably arranged on the side wall of the positioning rod 9. A gear 4 meshing with the first rack 20 is fixedly connected to the outer surface of the first rotating shaft 5. A ring 13 capable of moving along the length direction of the positioning rod 9 is slidably sleeved on the outer surface of the positioning rod 9. A second rack 21 capable of sliding horizontally and meshing with the gear 4 is fixedly connected transversely to the rear side of the ring 13. The other side of the mounting disc 2 is fixedly connected with a hydraulic cylinder 3. One end of the positioning rod 9 is fixedly connected to the end of the piston rod of the hydraulic cylinder 3.

[0026] When the positioning rod 9 is at the rearmost end, the ring 13 is also at the rearmost end, and a certain distance is formed between the surface of the positioning rod 9 and the front end of the positioning rod 9. When the positioning rod 9 moves forward, it will drive the gear 4 and the second rack 21 to move forward synchronously. The movement of the gear 4 along the first rack 20 causes the gear 4 to rotate. The gear 4 drives the second rack 21 to move forward relative to the positioning rod 9, so that while the ring 13 moves together with the positioning rod 9, it will also move forward relative to the positioning rod 9. When the positioning rod 9 extends forward, the ring 13 will accelerate and move to the front end of the surface of the positioning rod 9.

[0027] When the positioning rod 9 moves backward from the foremost end, the ring 13 is at the front end of the surface of the positioning rod 9. The backward movement of the positioning rod 9 drives the gear 4 and the second rack 21 to move backward synchronously. Under the action of the first rack 20, the gear 4 rotates back, so that while the second rack 21 moves synchronously with the positioning rod 9, it will also move backward relative to the positioning rod 9. The ring 13 will also move backward relative to the positioning rod 9 under the drive of the second rack 21, so that the ring 13 moves to the rearmost end and is located in the middle section of the surface of the positioning rod 9 to achieve reset.

[0028] During feeding, the positioning rod 9 extends a certain distance, located between the foremost end and the rearmost end. At this time, the ring 13 is also between the foremost end and the rearmost end on the positioning rod 9, so that a placement space is formed on the front side of the surface of the positioning rod 9 by the ring 13. Then the electric coil is hung on the positioning rod 9, and the electric coil is located between the three limiting rollers. The two lower second limiting rollers 17 rise to cooperate with the first limiting roller 8 to clamp the electric coil to complete the fixation. Then the positioning rod 9 retracts a certain distance to disengage from the electric coil. At this time, both the positioning rod 9 and the ring 13 are at the rearmost end, and then winding is carried out.

[0029] During unloading, the positioning rod 9 extends out again and inserts into the electric coil. Then, the two second limiting rollers 17 descend and disengage from the electric coil, causing the electric coil to lose support. The electric coil drops and hangs on the positioning rod 9. At this time, the positioning rod 9 continues to extend, and the circular ring 13 will move forward relative to the positioning rod 9 while moving synchronously with the positioning rod 9. When the positioning rod 9 moves to the forefront, the circular ring 13 is also at the forefront, pushing out the electric coil to complete unloading. After unloading is completed, the positioning rod 9 retracts a certain distance, causing the circular ring 13 to retract a certain distance relative to the positioning rod 9. The two are in the loading position for loading, thus realizing one cycle.

[0030] The circular ring 13 is driven to move by the gear 4, so that the circular ring 13 moves synchronously with the positioning rod 9 and also moves relative to the positioning rod 9. After winding is completed, when the positioning rod 9 extends with the electric coil, the circular ring 13 can accelerate and extend to push out the electric coil to achieve automatic unloading. This enables the fixing mechanism to have the function of automatic unloading without the need for manual or robotic assistance for unloading, with higher automation and stronger practicality.

[0031] The movement of the positioning rod 9 is controlled by controlling the extension or contraction of the hydraulic cylinder 3.

[0032] Furthermore, a first motor 6 is fixedly connected to the rear side of the fixed disk 7. The output shaft of the first motor 6 rotatably extends to the front side of the fixed disk 7 and is fixedly connected to a second rotating shaft 10. The first limiting roller 8 is sleeved on the surface of the second rotating shaft 10, and first limiting disks 12 are arranged at both ends of the first limiting roller 8.

[0033] Start the first motor 6 to rotate its output shaft and the second rotating shaft 10, thereby driving the first limiting roller 8 to rotate. After the inductor contacts the first limiting roller 8 and is driven by it, it will start to rotate. The stability of the inductor during winding work is ensured by the first limiting disks 12 and it will not deviate.

[0034] Furthermore, a moving seat 11 is arranged on the front side of the fixed disk 7. A second motor 19 is arranged on the bottom plate 1. The output shaft of the second motor 19 is fixedly connected to a threaded rod 15. A threaded sleeve 18 is threadedly connected to the outer surface of the threaded rod 15. The top of the moving seat 11 is fixedly connected to the surface of the threaded sleeve 18. The front side of the moving seat 11 is fixedly connected to a third rotating shaft 16. The second limiting roller 17 is rotatably sleeved on the surface of the third rotating shaft 16, and second limiting disks 22 are fixedly connected to both ends of the second limiting roller 17.

[0035] The moving seat 11 is slidably connected to the front side of the fixed disk 7. The rotation of the threaded rod 15 drives the threaded sleeve 18 to move up and down, thereby driving the moving seat 11 to move up and down, and then driving the two second limiting rollers 17 to move up and down to clamp or release the electric coil.

[0036] Start the second motor 19 so that its output shaft drives the threaded rod 15 to rotate, thereby driving the threaded sleeve 18 to move along its axial direction. At the same time, the moving seat 11 and the third rotating shaft 16 will also move accordingly. The second limiting roller 17 clamps the inductor. Since the second limiting roller 17 can rotate, when the first limiting roller 8 rotates, it can drive the electric coil to rotate, and the electric coil rotates relative to the second limiting roller 17.

[0037] Further, a placement groove 14 for the ring 13 and the positioning rod 9 to pass through is formed on the surface of the fixed disk 7. Thus, the ring 13 and the positioning rod 9 can move freely on the fixed disk 7.

[0038] Further, a guiding strip 24 is arranged on the outer surface of the positioning rod 9, and a sliding groove 23 adapted to the guiding strip 24 is formed on the inner wall of the positioning rod 9.

[0039] The ring 13 can slide on the outer surface of the positioning rod 9.

[0040] The working principle and usage process of the present utility model: After the present utility model is installed, when feeding is required, the positioning rod 9 is driven by the hydraulic cylinder 3 to extend forward a certain distance, at a position between the frontmost end and the rearmost end. At this time, the ring 13 on the positioning rod 9 is also at a position between the frontmost end and the rearmost end, so that a placement space is formed on the front side of the surface of the positioning rod 9 by the ring 13. Then, the electric coil is hung on the positioning rod 9, and the electric coil is located between the three limiting rollers. The two lower second limiting rollers 17 are raised to cooperate with the first limiting roller 8 to clamp the electric coil to complete the fixation. Then, the positioning rod 9 retracts a certain distance to disengage from the electric coil. At this time, both the positioning rod 9 and the ring 13 are at the rearmost end. Then, winding is carried out. When discharging is required, the positioning rod 9 extends again and inserts into the electric coil. Then, the two second limiting rollers 17 descend to disengage from the electric coil, causing the electric coil to lose support. The electric coil drops and hangs on the positioning rod 9. At this time, the positioning rod 9 continues to extend, and the ring 13 will move forward relative to the positioning rod 9 while moving synchronously with the positioning rod 9. When the positioning rod 9 moves to the frontmost end, the ring 13 is also at the frontmost end, pushing out the electric coil to achieve discharging. After discharging is completed, the positioning rod 9 retracts a certain distance, causing the ring 13 to retract a certain distance relative to the positioning rod 9, and the two are in the feeding position to carry out feeding, realizing a cycle, pushing out the electric coil to achieve automatic discharging, so that the fixing mechanism has the function of automatic discharging without the need for manual or manipulator-assisted discharging, with higher automation and stronger practicability.

[0041] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
