Description

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil, and iron core (magnetic core).

[0025] The mounting shell 1 is connected to a rotating support 5, and the inner wall of the mounting shell 1 is connected to a winding component 6, which includes a rotating ring 606, and the bottom of the rotating ring 606 is rotatably connected to the rotating support 5. A gear B601 is rotatably connected inside the mounting shell 1, and the gear B601 is meshed with the gear A401. The side of the gear B601 away from the mounting shell 1 is connected to a bevel gear assembly 602, and the other end of the bevel gear assembly 602 is connected to a transmission assembly B603, and the end of the transmission assembly B603 away from the bevel gear assembly 602 is connected to a gear C604, and the bottom of the gear C604 is rotatably connected to the top of the rotating support 5, and the top of the rotating support 5 is rotatably connected to two gears D605, and the two gears D605 is meshed with gear C604, an inner gear ring 607 is connected to the inner side of rotating ring 606, two gears D605 are meshed with the inner gear ring 607, rotating ring 606 is provided with a notch, one end of the notch of rotating ring 606 is rotatably connected with winding roller 7, and the winding accuracy of the device can be effectively improved by rotating the rotating ring 606, and since the rotating ring 606 is always in horizontal rotation, the problem of the coil generated by winding being tilted is avoided, and at the same time, since the structure of transmission component B603 can ensure that the rotating ring 606 and the roller 405 rotate synchronously, it is ensured that the winding speed of the device can be adjusted according to the rotation speed of the iron core, and the density of the coil generated by winding is fixed;
[0026] Further, the bevel gear assembly 602 includes two bevel gears, one of which is connected to the gear B601, and the other is connected to the transmission assembly B603, the two bevel gears are meshed and connected with each other, the rotation axes of the two bevel gears are perpendicular to each other, and the rotation transmission direction can be changed through the structure of the bevel gear assembly 602, and the transmission assembly B603 includes two transmission shafts and a connecting belt, the two transmission shafts are respectively connected to the bevel gear assembly 602 and the gear C604, and the two transmission shafts are connected to each other through the connecting belt;
[0027] Furthermore, a through hole is provided on the mounting housing 1, a blocking protrusion is provided on the inner wall of the limiting ring 404, and a notch is provided on the limiting ring 404, and the notch of the limiting ring 404 faces the direction of the rotating ring 606. The structure of the blocking protrusion can improve the installation accuracy of the iron core inside the limiting ring 404, avoiding problems such as inaccurate winding due to misalignment of the iron core. At the same time, the notch facing the rotating ring 606 can ensure that when the rotating ring 606 rotates horizontally, the cable of the winding roller 7 can be directly wound on the surface of the iron core, avoiding problems such as secondary processing;
[0028] Furthermore, the top of the inner wall of the limiting ring 404 is connected with an extrusion wheel assembly 8, which includes an elastic telescopic rod and a roller bracket. A through hole is provided at the top of the limiting ring 404, and the elastic telescopic rod is connected to the top of the outer side of the limiting ring 404. The bottom sliding end of the elastic telescopic rod passes through the through hole of the limiting ring 404 and is connected to the roller bracket. The roller bracket is rotatably connected with the extrusion wheel. The extrusion wheel at the top can prevent the iron core from jumping up during the process of being driven by the roller 405. In actual use, the outer diameter of the iron core is smaller than the inner diameter of the limiting ring 404, so that the iron core is placed inside the device. The surface of the iron core is transmitted by the roller 405, thereby achieving the effect of uniform winding of the device. As the winding process progresses, the outer diameter of the iron core will increase after the cable is wound on the surface of the iron core. At this time, the enlarged iron core will squeeze the extrusion wheel upward, thereby ensuring that it is always in close contact with the roller 405 during the winding process, ensuring the stability of the transmission process. Similarly, the combination of the extrusion wheel and the elastic telescopic rod can enable the device to process some iron cores with smaller diameters compatibly, thereby improving the compatibility of the device.
[0029] Specifically, the distance between the two gears D605 is greater than the width of the gap of the rotating ring 606, and the distance between the two rollers 405 is greater than the width of the gap of the limiting ring 404. The method of transmitting the rotating ring 606 through the two gears D605 can ensure that during the rotation of the rotating ring 606, there is always at least one gear D605 engaged with the internal gear ring 607 inside the rotating ring 606, thereby ensuring the continuous stability of the rotation transmission of the device and avoiding the interruption of the rotation of the rotating ring 606 due to the gap.
[0030] The transmission component A402 includes a pulley and a transmission belt. The pulley is connected to the side of the gear A401. The pulley is connected to the friction wheel 403 through a transmission belt. The transmission component B603 has the same structure as the transmission component A402.
[0031] A motor bracket is disposed outside the mounting housing 1 , a rotating motor is connected to the top of the motor bracket, and an output end of the rotating motor is connected to the driving gear 2 .
[0032] The rotating ring 606 is provided with a rotating bracket, which is rotatably connected to the winding roller 7. The rotating bracket is provided with a rotating damping member, which is in contact with the side of the winding roller 7. The structure of the rotating damping member can generate rotational resistance to the rotation of the winding roller 7, thereby preventing the coil from being wound too loosely on the surface of the iron core.
[0033] This device can realize the automated winding processing effect on the side of the iron core. The automated winding structure of this device can ensure that the winding angle is always in a horizontal state, ensuring the stability of the winding effect, avoiding the introduction of human errors in the iron core processing process, and improving the mechanical automation level of the coil processing process.
[0034] When the device is in working condition, the notch of the rotating ring 606 can facilitate the feeding of the device. When the device needs to put an iron core, the rotating ring 606 is rotated to an angle consistent with the opening direction of the limiting ring 404, and the iron core is put into the limiting ring 404 of the device. At this time, half of the rotating ring 606 is located on the inner side of the iron core, and the other half of the rotating ring 606 is located on the outer side of the iron core. When the iron core is placed in the limiting ring 404, it contacts the iron core through the roller 405, so that the iron core can be driven to rotate through the roller 405.
[0035] When the device is started, the driving gear 2 is driven to rotate by rotating the motor, and the driving gear 2 drives the transmission gear 3 to rotate. The transmission gear 3 transmits the two sets of gears A401. The two sets of gears A401 can drive the two friction wheels 403 to rotate through their respective transmission components A402. The friction wheels 403 rotate the rollers 405 to achieve the rotation effect of the iron core. The limiting ring 404 and the limiting protrusion can limit the rotation of the iron core, thereby ensuring the rotation stability of the iron core of the device.
[0036] During the rotation of the iron core, the rotation direction can be changed by the combination of gear B601 and bevel gear assembly 602. The structure of bevel gear assembly 602 can realize the rotation directions perpendicular to each other and maintain the transmission connection. The structural combination of bevel gear assembly 602 and transmission assembly B603 can realize that when gear A401 and gear B601 rotate, gear C604 is driven to rotate at the same time, and gear C604 drives two gears D605 to rotate, so that the rotating ring 606 can be transmitted on both sides of the inner toothed ring 607 on the inner wall of the rotating ring 606. The spacing between the two gears D605 is greater than the width of the notch of the rotating ring 606, which can effectively ensure the stability of the rotation transmission of the rotating ring 606, and ensure that when the rotating ring 606 rotates to any position, there is at least one gear D605 in a meshing connection state with the inner toothed ring 607, thereby ensuring the stability of the use of the device. The combination of bevel gear assembly 602 and transmission assembly B603 can achieve the effect of synchronous horizontal rotation of the rotating ring 606 while the iron core rotates.
[0037] During the horizontal rotation of the rotating ring 606, since the rotation center of the rotating ring 606 is inconsistent with the center of the side of the iron core, the winding roller 7 will rotate eccentrically with the center of the iron core when it is driven by the rotating ring 606 to rotate horizontally during the actual rotation of the rotating ring 606, resulting in a change in the distance between the winding roller 7 and the center of the side of the iron core. When the winding roller 7 rotates to a position away from the iron core, too much cable will be extended. At this time, the combination of the rotating bracket and the rotating damping member can ensure that the cable is in a tensioned state during the process of the winding roller 7 paying out the cable. When the winding roller 7 approaches the iron core, the approach speed is greater than the cable winding speed. At this time, the cable is loosely wound on the side of the iron core. When the cable is in a relaxed state, with the cooperation of the rotating damping member, the winding The roller 7 does not rotate in the process of approaching the iron core, thereby tightening the cable during the winding process. When too much cable has been extended and wound on the iron core due to being away from the iron core, the cable is tensioned again. At the moment of tensioning, the cable wound on the side of the iron core will change from a relaxed state to a tensioned state. At the same time, the tensioned state can drive the winding roller 7 to rotate again, thereby achieving the effect of releasing the wire again. The device can effectively avoid the problem of excessive wire release caused by rotational inertia during the revolution of the winding roller 7 through the structure of the rotating damping member. In addition, in the eccentric rotation process of the winding roller 7 relative to the iron core, the alternating winding method of excessive wire release and stopping rotation to tighten the cable can ensure that the cable wound on the surface of the iron core is tight, and at the same time, it ensures that the cable on the winding roller 7 is in a tensioned state during the winding process.
