Description

Technical Field

[0001] This utility model relates to the field of transformer wire winding technology, and more specifically, to a transformer wire winding machine. Background Technology

[0002] Transformer wire refers to the enameled wire used to change voltage in a transformer. A transformer consists of an iron core (or magnetic core) and coils. The coils have two or more windings, of which the winding connected to the power supply is called the primary coil, and the remaining windings are called secondary coils. It can transform AC voltage, current, and impedance. A simple iron-core transformer consists of an iron core made of soft magnetic material and two coils with different numbers of turns wound around the iron core. The function of the iron core is to strengthen the magnetic coupling between the two coils. The transformer wire is wound on the outside of the iron core. The iron core includes toroidal iron cores and horseshoe iron cores.

[0003] Traditional horseshoe-shaped iron cores have an open structure, allowing for direct winding. However, toroidal iron cores do not have an open structure, making it inconvenient for traditional winding machines to perform direct continuous winding. Manual winding is required, which is quite troublesome. During manual winding, workers need to pass the end of the transformer wire through the hole in the toroidal iron core. Due to the large number of turns, manual operation is difficult, has a high repetition rate, is quite troublesome, and has low work efficiency. Further improvements can be made. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a variable voltage wire winding machine, which has the advantage of improved work efficiency, thereby solving the problems mentioned in the background technology.

[0006] (II) Technical Solution

[0007] To achieve the aforementioned advantages of improved work efficiency, the specific technical solution adopted by this utility model is as follows: A transformer wire winding machine includes a mounting frame, an annular iron core, a first gear ring, and a second gear ring. A drive gear and a side gear are rotatably connected to the inner side of the mounting frame via a gear frame. The drive gear and the side gear are of the same size. The mounting frame has a slotted structure and is made of metal, making it resistant to deformation. A second driven worm gear is fixedly mounted on one end of the drive gear. Specifically, a second driven worm gear is fixedly mounted on one end of the drive gear shaft. The first gear ring and the drive gear mesh with each other. The first gear ring and the second gear ring combine to form a continuous annular structure. One end of the first gear ring and the second gear ring are hinged for easy opening, and the other ends of the first gear ring and the second gear ring are fixedly connected via a pin assembly. The pin assembly is a common fixing structure and will not be described in detail here. The inner side of the first gear ring is rotatably connected via an inner frame. The device includes a wire feeding roller with a transformer wire mounted on its surface. A drive shaft and a driven shaft are rotatably connected to the bottom surface of the mounting frame via a rotating connecting seat. The drive shaft and driven shaft are coaxially arranged with the rotating connecting seat, which is a common axial rotational connection structure, facilitating the rotation of the drive shaft and driven shaft. A drive roller is fixedly connected to the top of the drive shaft and driven shaft, and a compression sleeve is fixedly fitted onto the outer wall of the drive roller. The compression sleeve can be deformed under pressure, facilitating the continuous rotation of the annular iron core. The annular iron core abuts against the compression sleeves. A first driven worm gear is fixedly fitted onto the bottom outer surface of the drive shaft, a common component. A drive motor is fixedly mounted at one end of the mounting frame, and a first worm is mounted at the output end of the drive motor. A second worm is fixedly connected to the other end of the first worm via a shaft. The first worm, shaft, and second worm are coaxially arranged, and the first and second worms mesh with the first and second driven worm gears respectively, a common meshing connection form.

[0008] Furthermore, the drive rollers are distributed in three sets at equal angles along the central axis of the annular iron core, which facilitates the stabilization of the annular iron core, and the height of the drive shaft is greater than the thickness of the annular iron core, thereby improving the clamping stability of the annular iron core.

[0009] Furthermore, the side gears are arranged in three sets, with two side gears installed on the top surface inside the mounting frame and the other side gear installed on the bottom surface inside the mounting frame. The side gears play a role in stabilizing the rotation of the first and second gear rings.

[0010] Furthermore, the other end of the inner frame is fixedly connected to an end plate by fixing screws, and both the surface of the end plate and the surface of the other end of the inner frame are provided with shaft holes. The operator can remove the fixing screws to open the end plate, thereby facilitating the installation and removal of the wire feeding roller and making it easy to replace the wire feeding roller.

[0011] Furthermore, the roller shafts at both ends of the pay-off roller pass through shaft holes, and the diameter of the shaft holes is larger than the outer diameter of the roller shaft of the pay-off roller. The roller shaft of the pay-off roller rotates inside the shaft holes, which facilitates pay-off.

[0012] Furthermore, the extrusion sleeve adopts an elastic structure, and the outer surface of the extrusion sleeve is roughened. The extrusion sleeve can be made of rubber and can be deformed. After the annular iron core is wound, the outer diameter increases. The deformation of the extrusion sleeve facilitates the continuous rotation of the annular iron core.

[0013] Furthermore, the side gear and the drive gear are rotatably connected to the gear carrier via a gear shaft, which is a common installation structure.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a variable voltage wire winding machine, which has the following beneficial effects:

[0016] (1) This utility model is provided with a first toothed ring, a second toothed ring, an inner frame, a wire feeding roller, and an annular iron core. When the operator winds the annular iron core into a transformer wire, he can open the pin assembly, rotate the second toothed ring along the hinge, and then insert the annular iron core into the annular gear formed by the first toothed ring and the second toothed ring. Then, the second toothed ring is locked by the pin assembly, and the annular iron core is placed between three drive rollers distributed at equal angles. The annular iron core is pressed against the surface of the drive roller by the extrusion sleeve. Then, the wire feeding roller is installed between the inner frames, and one end of the transformer wire is led out and wound to the outer surface of the annular iron core. The drive motor can then be started. The shaft rotates, which in turn drives the first and second worm gears, which in turn drive the first and second driven worm wheels, which in turn drive the drive roller, which in turn drives the annular iron core. The second driven worm wheel drives the drive gear, which in turn drives the first and second gear rings, which in turn drive the inner frame and the pay-off roller to rotate. While the inner frame and the pay-off roller revolve around the central axis of the first and second gear rings, the pay-off roller rotates under the pull of the transformer wire to pay off the wire, thus completing the annular winding of the annular iron core and completing the winding of the closed annular structure. This eliminates the trouble of manual winding and improves production efficiency and work efficiency.

This device uses a single drive motor to drive the shaft to rotate, which can drive the first worm and the second worm to rotate, which can drive the first driven worm wheel and the second driven worm wheel to rotate synchronously, which can drive the first toothed ring, the second toothed ring and the annular iron core to rotate synchronously. The synchronization rate is high, the winding efficiency is higher, the structure is simpler and the use is more convenient. Attached Figure Description

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0029] According to an embodiment of the present invention, a transformer wire winding machine is provided.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-7As shown, a transformer winding machine according to an embodiment of the present invention includes a mounting frame 1, an annular iron core 10, a first gear ring 2, and a second gear ring 5. A drive gear 3 and a side gear 4 are rotatably connected to the inner side of the mounting frame 1 via a gear frame 17. The drive gear 3 and the side gear 4 are of the same size. The mounting frame 1 has a groove-shaped structure and is made of metal, making it resistant to deformation. A second driven worm gear 18 is fixedly mounted on one end of the drive gear 3. Specifically, the second driven worm gear 18 is fixedly mounted on one end of the gear shaft of the drive gear 3. The first gear ring 2 and the second gear ring 5 mesh between the side gear 4 and the drive gear 3. The first gear ring 2 and the second gear ring 5 combine to form a continuous annular structure. One end of the first gear ring 2 and the second gear ring 5 is hinged by a hinge 6 for easy opening. The first toothed ring 2 and the second toothed ring 5 are fixedly connected at their other ends by a pin assembly 7. The pin assembly 7 is a common fixing structure and will not be described in detail here. The inner side of the first toothed ring 2 is rotatably connected to a wire feeding roller 9 via an inner frame 8. A transformer wire is mounted on the surface of the wire feeding roller 9. The inner bottom surface of the mounting frame 1 is rotatably connected to a drive shaft 13 and a driven shaft 16 via a rotary connecting seat 15. The drive shaft 13 and the driven shaft 16 are coaxially arranged with the rotary connecting seat 15. The rotary connecting seat 15 is a common axial rotation connection structure, which facilitates the rotation of the drive shaft 13 and the driven shaft 16. The top of the drive shaft 13 and the driven shaft 16 is fixedly connected to a drive roller 11, and a compression sleeve 12 is fixedly sleeved on the outer wall of the drive roller 11. The compression sleeve 12 can be deformed under pressure, which facilitates the continuous rotation of the annular iron core 10. An annular iron core 10 abuts between the extrusion sleeves 12. A first driven worm gear 14 is fixedly sleeved on the bottom outer surface of the drive shaft 13. These are common parts. A drive motor 19 is fixedly mounted on one end of the mounting bracket 1, and a first worm 21 is mounted on the output end of the drive motor 19. The other end of the first worm 21 is fixedly connected to a second worm 22 via a shaft 20. The first worm 21, shaft 20, and second worm 22 are arranged coaxially. The first worm 21 and the second worm 22 mesh with the first driven worm gear 14 and the second driven worm gear 18, respectively. This is a common meshing connection. When the operator winds the annular iron core 10 into the transformer wire, they can open the pin assembly 7, rotate the second toothed ring 5 along the hinge 6, and then insert the annular iron core 10 into the first toothed ring 2 and the second toothed ring 5. Inside the formed annular gear, the second gear ring 5 is then locked by the pin assembly 7, and the annular iron core 10 is placed between three equally angled drive rollers 11. The extrusion sleeves 12 on the surface of the drive rollers 11 press against the annular iron core 10. Then, a wire feeding roller 9 is installed between the inner frames 8, and one end of the transformer wire is led out and wound onto the outer surface of the annular iron core 10. The drive motor 19 can then be started to drive the shaft 20 to rotate. The rotation of the shaft 20 drives the first worm 21 and the second worm 22 to rotate, and simultaneously drives the first driven worm wheel 14 and the second driven worm wheel 18 to rotate, which in turn drives the drive rollers 11 to rotate, which in turn drives the annular iron core 10 to rotate. The second driven worm wheel 18 drives the drive gear 3 to rotate, which in turn drives the first gear ring 2 and the second gear ring 5 to rotate, which in turn drives the inner frames 8 and the wire feeding roller 9 to rotate.While the inner frame 8 and the pay-off roller 9 revolve around the central axis of the first toothed ring 2 and the second toothed ring 5, the pay-off roller 9 rotates under the pull of the transformer wire to pay off the wire, thereby completing the annular winding of the toroidal iron core 10 and completing the winding of the closed annular structure. This eliminates the trouble of manual winding and improves production efficiency and work efficiency. At the same time, this device uses a single drive motor 19 to drive the shaft 20 to rotate, which in turn drives the first worm 21 and the second worm 22 to rotate, which in turn drives the first driven worm wheel 14 and the second driven worm wheel 18 to rotate synchronously, which in turn drives the first toothed ring 2, the second toothed ring 5 and the annular iron core 10 to rotate synchronously. The synchronization rate is high, the winding efficiency is higher, the structure is simpler, and the use is more convenient.

[0031] In one embodiment, the drive rollers 11 are distributed in three groups at equal angles along the central axis of the annular core 10, which facilitates the stabilization of the annular core 10, and the height of the drive shaft 13 is greater than the thickness of the annular core 10, thereby improving the clamping stability of the annular core 10.

[0032] In one embodiment, three sets of side gears 4 are arranged, with two side gears 4 mounted on the inner top surface of the mounting frame 1 and the other side gear 4 mounted on the inner bottom surface of the mounting frame 1. The side gears 4 serve to stabilize the rotation of the first gear ring 2 and the second gear ring 5.

[0033] In one embodiment, the other end of the inner frame 8 is fixedly connected to an end plate 23 by a fixing screw 24, and both the surface of the end plate 23 and the surface of the other end of the inner frame 8 are provided with shaft holes 25. The operator can remove the fixing screw 24 to open the end plate 23, thereby facilitating the installation and removal of the wire feeding roller 9 and making it easier to replace the wire feeding roller 9.

[0034] In one embodiment, the roller shafts at both ends of the pay-off roller 9 pass through the shaft hole 25, and the diameter of the shaft hole 25 is larger than the outer diameter of the roller shaft of the pay-off roller 9. The roller shaft of the pay-off roller 9 rotates inside the shaft hole 25, which facilitates pay-off.

[0035] In one embodiment, the extrusion sleeve 12 adopts an elastic structure, and the outer surface of the extrusion sleeve 12 is roughened. The extrusion sleeve 12 can be made of rubber and can be deformed. After the annular iron core 10 is wound, the outer diameter increases. The deformation of the extrusion sleeve 12 facilitates the continuous rotation of the annular iron core 10.

[0036] In one embodiment, the side gear 4 and the drive gear 3 are rotatably connected to the gear carrier 17 via a gear shaft, which is a common mounting structure.

[0037] Working principle: When the operator winds the transformer wire into the annular core 10, they can open the pin assembly 7, rotate the second toothed ring 5 along the hinge 6, and insert the annular core 10 into the annular gear formed by the first toothed ring 2 and the second toothed ring 5. Then, the pin assembly 7 locks the second toothed ring 5, and the annular core 10 is placed between three equally angled drive rollers 11. The extrusion sleeves 12 on the surface of the drive rollers 11 press against the annular core 10. Then, a wire feeding roller 9 is installed between the inner frames 8, and one end of the transformer wire is led out and wound onto the outer surface of the annular core 10. The drive motor 19 is then started, driving the shaft 20 to rotate. The rotation of the shaft 20 drives the first worm gear 21 and the second worm gear 22 to rotate, simultaneously driving the first driven worm wheel 14 and the second driven worm wheel 18 to rotate, driving the drive roller 11 to rotate, and driving the annular core 10 to rotate. The two driven worm gears 18 drive the driving gear 3 to rotate, which in turn drives the first gear ring 2 and the second gear ring 5 to rotate, and in turn drives the inner frame 8 and the pay-off roller 9 to rotate. While the inner frame 8 and the pay-off roller 9 revolve around the central axis of the first gear ring 2 and the second gear ring 5, the pay-off roller 9 rotates on its own axis under the pull of the transformer wire, thereby completing the annular winding of the ring core 10 and completing the winding of the closed annular structure. This eliminates the trouble of manual winding and improves production efficiency and work efficiency. At the same time, this device uses a single drive motor 19 to drive the shaft 20 to rotate, which can drive the first worm 21 and the second worm 22 to rotate, which can drive the first driven worm gear 14 and the second driven worm gear 18 to rotate synchronously, which can drive the first gear ring 2, the second gear ring 5 and the annular core 10 to rotate synchronously. The synchronization rate is high, the winding efficiency is higher, the structure is simpler, and the use is more convenient.
