Description

Technical Field

[0001] This utility model relates to the field of shaping mechanism technology, and in particular to a shaping mechanism for the coil taps of a network transformer. Background Technology

[0002] The coil tap is an important part of the network transformer. It plays a role in connecting, transmitting and converting signals. Through reasonable coil tap design, functions such as signal transmission, coupling and filtering can be realized, thereby meeting the needs of network communication. In the production process of network transformer, the coil tap stranded wire needs to be shaped and processed by a shaping mechanism.

[0003] In some network transformer designs, to enhance the connection strength and stability between coils and improve the transmission effect of network signals, the taps may be designed to be twisted into a braid shape. This shaping method can improve the coupling effect between wires, reduce parasitic parameters and stray capacitance, and enhance transmission capability. At the same time, the braid shape also helps to reduce the loss during network signal transmission and enhance the anti-interference capability of network signals.

[0004] Currently, when shaping the stranded wire of a network transformer coil, it is not convenient to position the taps on the side closest to the coil. This results in a large stranding force, which can easily cause the taps to fall off the coil. On the other hand, if the stranding force is too small, the quality of the stranding will be low. Furthermore, the coil needs to be fixed before stranding, and traditional tooling fixtures are not easy to disassemble the coil, thus reducing the processing efficiency. Utility Model Content

[0005] The purpose of this utility model is to solve the problem in the prior art that it is not convenient to position the taps when shaping the coil taps of a network transformer, and to propose a coil tap shaping mechanism for a network transformer.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A network transformer coil tap shaping mechanism includes a frame and a positioning frame detachably mounted on the frame. It further includes: a mounting rod fixedly mounted on the frame, the mounting rod having a fixing member for positioning the coil, and a linkage member for fixing the tap; and a gear mounted on the positioning frame and arranged opposite each other along the axis of the positioning frame, the gear having a limit hole, and a driving member for driving the gear to rotate on the positioning frame.

[0008] For securing the coil, preferably, the fastener includes: a gas pipe fixedly connected to the mounting rod; a piston rod slidably connected to the mounting rod, with a pressure block fixedly connected to the end of the piston rod away from the gas pipe, wherein a first tension spring is provided at the end of the piston rod away from the pressure block and fixedly connected to the mounting rod and the piston rod; at least two sets of limiting blocks slidably connected to the mounting rod, the limiting blocks having a tendency to move away from the center of the mounting rod, and the inclined surface of the limiting block contacting the inclined surface of the pressure block; and at least two sets of springs, with both ends of the springs fixedly connected to the limiting blocks and the pressure blocks respectively.

[0009] To secure the tap near the coil side, preferably, the linkage includes a positioning frame fixedly sleeved on the mounting rod, a locking block fixedly connected to the positioning frame and arranged opposite each other along the axis of the positioning frame, a locking plate slidably connected to the positioning frame and arranged opposite each other along the axis of the positioning frame, wherein the locking plate has a tendency to move towards the locking block, an inclined block fixedly connected to the locking plate, a pressure rod provided on the inclined surface of the inclined block, and the pressure rod fixedly mounted on the piston rod.

[0010] To further limit the lateral movement of the card plate, a limiting rod is slidably connected inside the card plate, with both ends of the limiting rod extending outside the card plate.

[0011] To further reset the card plate, a second tension spring is fitted on the limiting rod, with both ends of the second tension spring fixedly connected to the card plate.

[0012] To achieve the stranding and shaping of the tap, preferably, the driving component includes: a motor, fixedly mounted on the positioning frame, the output end of the motor being fixedly connected to a gear; and a toothed synchronous belt, meshing with the gear.

[0013] Compared with the prior art, this utility model provides a network transformer coil tap shaping mechanism, which has the following beneficial effects:

[0014] 1. The network transformer coil tap shaping mechanism, by setting a driving component to drive two gears to rotate, can shape the tap stranded wire, and the gears are provided with multiple limit holes, which can improve the adaptability of the tap stranded wire shaping.

At the same time, during the process of fixing the coil, the linkage component moves with the piston rod in the fixing component, which can fix the tap near the coil side, and prevent the tap from falling off the coil due to excessive force during the twisting process, thereby improving the quality of the tap shaping process.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

Therefore, they should not be construed as limitations on this utility model.

[0026] Example:

[0027] Reference Figures 1-6 A network transformer coil tap shaping mechanism includes a frame 1, on which a positioning frame 5 is detachably mounted. The positioning frame 5 is fixedly connected to the frame 1 by screws. The mechanism also includes: a mounting rod 2 fixedly mounted on the frame 1, the mounting rod 2 having a hollow structure and a fixing member 3 for positioning the coil; a linkage member 4 for fixing the tap; two gears 6 mounted on the positioning frame 5 and arranged opposite each other along the axis of the positioning frame 5; limit holes 7 on the gears 6; a driving member 8 on the positioning frame 5 for driving the gears 6 to rotate; the driving member 8 includes a motor 81 fixedly mounted on the positioning frame 5, the output end of the motor 81 being fixedly connected to one of the gears 6, and the other gear 6 being rotatably mounted on the positioning frame 5; and a toothed synchronous belt 82 meshing with the two gears 6.

[0028] Specifically, by setting the fixing component 3, the coil can be fixed. At the same time, during the process of fixing the coil, the linkage component 4 moves with the piston rod 32 in the fixing component 3, which can fix the tap near the coil side, preventing the tap from falling off the coil due to excessive force during the twisting process, thereby improving the quality of the tap shaping process.

[0029] The fixing component 3 includes two gas pipes 31 fixedly connected to the mounting rod 2, one of which is a gas supply pipe and the other is an exhaust pipe; a piston rod 32 slidably connected to the mounting rod 2, a sealing ring fixedly fitted on the piston rod 32, and the surface of the sealing ring contacting the inner wall of the mounting rod 2; a pressure block 33 fixedly connected to the end of the piston rod 32 away from the gas pipe 31, the pressure block 33 being an isosceles trapezoid; and two first tension springs 34 fixedly connected to the end of the piston rod 32 away from the pressure block 33; four sets of limiting blocks 35 slidably connected to the mounting rod 2, the limiting blocks 35 having a tendency to move away from the center of the mounting rod 2, and the inclined surface of the limiting blocks 35 contacting the inclined surface of the pressure block 33; and four sets of springs 36, the two ends of which are fixedly connected to the limiting blocks 35 and the pressure blocks 33 respectively.

[0030] Specifically, by setting the fixing component 3, when the gas pipe 31 inflates the mounting rod 2, the piston rod 32 drives the pressure block 33 to move, so that it squeezes the four sets of limiting blocks 35, which can fix the coil on the mounting rod 2, thereby improving the stability of the tap shaping process.

[0031] The linkage 4 includes a positioning frame 41 fixedly sleeved on the mounting rod 2. A locking block 42 is fixedly connected to the positioning frame 41 and is arranged opposite to each other along the axis of the positioning frame 41. A locking plate 43 is slidably connected to the positioning frame 41 and is arranged opposite to each other along the axis of the positioning frame 41. A limiting rod 46 is slidably connected inside the locking plate 43. Both ends of the limiting rod 46 extend through the outside of the locking plate 43. A second tension spring 47 is sleeved on the limiting rod 46. Both ends of the second tension spring 47 are fixedly connected to the locking plate 43. The locking plate 43 has a tendency to move closer to the locking block 42. An inclined block 44 is fixedly connected to the locking plate 43. A pressure rod 45 is provided on the inclined surface of the inclined block 44. The pressure rod 45 is composed of a triangular block and an L-shaped connecting rod. The pressure rod 45 is fixedly installed on the piston rod 32.

[0032] Specifically, by setting the linkage 4, when the fixing part 3 fixes the coil, the pressure rod 45 in the linkage 4 moves with the piston rod 32 in the fixing part 3, which can fix the tap, thereby preventing the tap from falling off during the twisting and shaping of the wire. At the same time, the limiting rod 46 can be used to limit the lateral movement of the clamping plate 43, and the second tension spring 47 can be used to reset the clamping plate 43, thereby improving its disassembly efficiency.

[0033] During the installation of the cable, the worker inserts the cable into the mounting rod 2 and arranges the tap so that it is positioned on the inner arc surface of the locking block 42. Then, the external air pump is started. When the air pump inflates the gas pipe 31, the pressure inside the mounting rod 2 will push the piston rod 32 to move. When the piston rod 32 moves, it stretches the first tension spring 34 and drives the pressure block 33 to move. When the pressure block 33 moves, it squeezes the four limiting blocks 35. The limiting blocks 35 are squeezed by the force and squeeze the spring 36, moving away from the center of the mounting rod 2. When the limiting blocks 35 move to the designated position, the cable can be fixed.

[0034] During the movement of piston rod 32, pressure rod 45 is moved. When pressure rod 45 moves, it squeezes two inclined blocks 44, causing the two inclined blocks 44 to drive two clamping plates 43 to slide laterally on positioning frame 41. When clamping plates 43 move, they can engage the tap in the clamping block 42, thereby fixing the tap near the coil side.

[0035] After the taps are fixed, the workers insert the taps one by one into the limiting holes 7. Then, they start the motor 81 using an external control switch. The output end of the motor 81 drives one of the gears 6 to rotate. When the gear 6 rotates, it drives the toothed synchronous belt 82 to rotate, causing the other gear 6 to rotate in the same direction. During the rotation, the taps can be twisted and shaped into a twisted shape. Furthermore, since the locking block 42 and the locking plate 43 lock one end of the tap, it can prevent the twisting force from being too great, which would cause the taps to fall off the coil.

[0036] After tapping is completed, the gas inside the mounting rod 2 is released, which resets the limit block 35 and the pressure rod 45, thereby improving the efficiency of coil assembly and disassembly.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
