A wire twisting machine used for the processing of network transformer magnetic core coils

Abstract

The present invention relates to a wire twisting machine used for processing the magnetic ring coil of a network transformer, comprising: a base, on one side of the base, a mounting plate is fixedly installed, on the side of the base far from the mounting plate, there is a turntable, and on the side of the turntable opposite to the mounting plate, a plurality of fixing members are installed. The present invention has a novel design. The rotating threaded rod causes the sliding block threaded thereon to move to one side, and the moving sliding block drives the support block thereon to move. Since the moving speed of the base is slow and the enameled wire will shorten during winding, the turntable will pull the support block connected thereto to move to one side, and the moving support block will push the abutting compression spring to compress, so that the enameled wire will not break when being twisted. Through the sliding block, the fixed cylinders on both sides of the device can approach each other when twisting the enameled wire, so that the length between the two fixed cylinders is suitable for the length after twisting the wire. At the same time, the installed compression spring straightens the contracted enameled wire, so that the coil will not knot.

Description

Technical Field

[0001] The present invention relates to the field of magnetic ring coil processing, and specifically to a wire twisting machine used for processing magnetic ring coils of network transformers. Background Art

[0002] Network transformers, also known as network isolation transformers, are simply referred to as "data pumps" or "network filters". Generally, the main assembly processes are divided into two categories: DIP and SMT. The main structure of network transformers includes: magnetic cores, casings, enameled wires, chemical materials, PIN pins, etc. In order to extend the service life of network transformers and expand the usage environment, organic materials are generally potted inside. The main potting materials are divided into two types: epoxy resin potting materials or silicone potting materials.

[0003] During the production of network transformers, a wire twisting machine is required to twist the wound enameled wires. However, the commonly used twisting machines twist the wires in a fixed manner. This twisting method is suitable for enameled wires with longer lengths. Network transformers use enameled wires with specific lengths. When such enameled wires are twisted, the length after twisting will become smaller. If the enameled wire fixed on the twisting machine is straight, it will cause the enameled wire to crack. If the enameled wire fixed on the twisting machine has a certain curvature, the enameled wire will knot. Summary of the Invention

[0004] The purpose of the present invention is to provide a wire twisting machine used for processing magnetic ring coils of network transformers to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A wire twisting machine used for processing magnetic ring coils of network transformers, comprising:

[0007] A base, on one side of which an installation plate is fixedly installed. On the side of the base away from the installation plate, there is a turntable. On the side of the turntable opposite to the installation plate, a plurality of fixing members are installed. The fixing members on one side are fixedly installed with the installation plate, while the fixing members on the other side are rotatably connected to the turntable, and the plurality of fixing members on the same side are placed in a triangular shape;

[0008] On one side of the base, there is a driving component connected to the turntable. The turntable is driven to rotate through the driving component. A pushing component is installed on the base. The pushing component is connected to the turntable, and the driving component is connected to the pushing component. The driving component drives the turntable to move through the pushing component;

[0009] A protective component is installed on the base to prevent the coil from breaking and causing harm to the human body.

[0010] As a further solution of the present invention: The fixing member includes a plurality of fixing cylinders fixedly installed on the mounting plate. An extrusion plate is fixedly installed inside the fixing cylinder. A pressing block abutted against the extrusion plate is arranged inside the fixing cylinder. A threaded hole is formed on the fixing cylinder, and a threaded knob rotatably connected to the pressing block is threadedly connected inside the threaded hole. A rubber ring is fixedly installed at one end of the fixing cylinder.

[0011] As a further solution of the present invention: A cylinder is fixedly installed on one side of the fixing cylinder. The cylinder penetrates through the turntable and extends to the other side of the turntable. A circular hole for the cylinder to rotate is formed on the turntable. A gear is fixedly installed at the end of the cylinder far from the fixing cylinder.

[0012] As a further solution of the present invention: The driving assembly includes a first rotating column fixedly installed on the turntable. A gear ring abutted against the turntable is rotatably connected to the first rotating column. The gear ring meshes with a plurality of gears. A second rotating column is arranged on one side of the first rotating column. Prismatic grooves are formed on both the first rotating column and the second rotating column. A prismatic rod is slidably connected inside the prismatic grooves.

[0013] As a further solution of the present invention: A driving box is fixedly installed on one side of the base. A servo motor is installed inside the driving box. A transmission belt is installed between the output shaft of the servo motor and the second rotating column.

[0014] As a further solution of the present invention: A limiting frame is fixedly installed on the base. The second rotating column is rotatably connected to a support frame for supporting it. The support frame is fixedly installed with the limiting frame. A support block fixedly installed with the gear ring is rotatably connected to the first rotating column.

[0015] As a further solution of the present invention: The pushing assembly includes a threaded rod arranged on the base. One end of the threaded rod is rotatably connected to the mounting plate. The other end of the threaded rod penetrates through the limiting frame and is fixedly installed with the output shaft of the servo motor. The threaded rod is threadedly connected to a sliding block threadedly connected to the limiting frame. A sliding groove is formed on the sliding block. A sliding rod is fixedly installed inside the sliding groove. The end of the support block far from the first rotating column is slidably connected inside the sliding groove and sleeved on the sliding rod. A compression spring sleeved on the sliding rod is abutted between the sliding groove and the support block.

[0016] As a further solution of the present invention: The protection assembly includes a rear protection plate arranged on the base. A fixing plate for supporting it is fixedly installed on the rear protection plate. The fixing plate is fixedly installed on the base. A front protection plate is arranged on one side of the rear protection plate. A plurality of hinge blocks are installed between the front protection plate and the rear protection plate. A handle is fixedly installed on the front protection plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention has a novel design. When the servo motor operates, since the second rotating column and the first rotating column are provided with prism grooves, the first rotating column can move to one side. Of course, while the first rotating column moves, it can also drive the first rotating column to rotate. The rotation of the first rotating column drives the turntable fixed to it to rotate. Since the gear rotates on the turntable, the gear will also rotate. And the gear ring meshing with multiple gears is fixed. Therefore, when the first rotating column drives the turntable to rotate, the gear rotates in one direction. The rotating threaded rod causes the sliding block threaded thereon to move to one side. The moving sliding block drives the support block thereon to move. Since the base moves at a slower speed and the enameled wire will shorten during winding, the turntable will pull the support block connected to it to move to one side. The moving support block pushes the abutting compression spring to compress, so that the enameled wire will not break when it is twisted. Through the sliding block, the fixed cylinders on both sides of the device can approach each other when twisting the enameled wire, making the length between the two fixed cylinders suitable for the length after twisting the wire. At the same time, the installed compression spring straightens the contracted enameled wire, so that the coil will not knot. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0027] In addition, the elements in the present invention are referred to as "fixed to" or "arranged on" another element. It can be directly on another element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to another element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0028] Please refer to Figures 1 - 7 , in the embodiment of the present invention, a wire twisting machine used for processing network transformer magnetic ring coils includes:

[0029] Base 1, one side of the base 1 is fixedly installed with a mounting plate 3, a turntable 9 is arranged on the side of the base 1 away from the mounting plate 3, a plurality of fixing parts are installed on the side of the turntable 9 opposite to the mounting plate 3, one side of the fixing parts is fixedly installed with the mounting plate 3, and the other side of the fixing parts is rotatably connected to the turntable 9, and the plurality of fixing parts on the same side are placed in a triangle.

[0030] Among them, a plurality of foot pads 2 are fixedly installed at the bottom of the 1, and the overall equipment is more stable during operation through the foot pads 2.

[0031] Please refer to Figure 2 , Figure 6, the fixing member includes a plurality of fixing cylinders 4 fixedly installed on the mounting plate 3. An extrusion plate 26 is fixedly installed inside the fixing cylinder 4. A pressing block 25 abuting against the extrusion plate 26 is provided inside the fixing cylinder 4. A threaded hole is formed in the fixing cylinder 4, and a threaded knob 10 rotatably connected to the pressing block 25 is threadedly connected inside the threaded hole. A rubber ring 27 is fixedly installed at one end of the fixing cylinder 4.

[0032] When the provided threaded knob 10 rotates forward, the rotating threaded knob 10 moves downward, and the moving threaded knob 10 pushes the pressing block 25 downward. During use, the enameled wire is inserted into the fixing cylinder 4. The downward-moving pressing block 25 presses the middle enameled wire through the lower extrusion plate 26 to fix the enameled wire. Since the fixing cylinder 4 will flip, the enameled wire will move closer to the center between the plurality of fixing cylinders 4. The flipped fixing cylinder 4 will cause the enameled wire to scrape off the insulating paint on it. The rubber ring 27 can prevent this situation from occurring. When the threaded knob 10 rotates in the reverse direction, the rotating threaded knob 10 drives the pressing block 25 away from the lower extrusion plate 26 to release the fixed enameled wire.

[0033] Of course, a circular hole is formed in the mounting plate 3, and the fixing cylinder 4 fixed on the mounting plate 3 is provided with a threaded hole. A screw threadedly connected to the threaded hole is rotatably connected inside the circular hole. The fixing cylinder 4 can be controlled through the screw, and at the same time, the number of fixing cylinders 4 and the number of turns of winding can also be controlled.

[0034] Please refer to Figure 2 、 Figure 3 、 Figure 5 , a cylinder is fixedly installed on one side of the fixing cylinder 4. The cylinder penetrates through the turntable 9 and extends to the other side of the turntable 9. The turntable 9 is provided with a circular hole for the cylinder to rotate. A gear 29 is fixedly installed at one end of the cylinder away from the fixing cylinder 4.

[0035] Specifically, the rotation of the turntable 9 drives the plurality of fixing cylinders 4 rotatably connected thereto to rotate around the central axis of the turntable 9 for winding. At the same time, when the gear 29 rotates, it will drive the fixing cylinder 4 to rotate through the cylinder. Since the turntable 9 will twist the enameled wire when rotating and twisting the wire.

[0036] Of course, a ball bearing for receiving the cylinder is fixedly installed inside the circular hole. Through the ball bearing, the rotation of the fixing cylinder 4 is more stable.

[0037] A driving component connected to the turntable 9 is provided on one side of the base 1. The turntable 9 is driven to rotate through the driving component.

[0038] Please refer to Figure 2 、 Figure 5 、Figure 7 The driving assembly includes a first rotating column 15 fixedly installed on the turntable 9. A gear ring 13 that abuts against the turntable 9 is rotatably connected to the first rotating column 15, and the gear ring 13 meshes with a plurality of the gears 29. A second rotating column 16 is provided on one side of the first rotating column 15. Prismatic grooves are formed in both the first rotating column 15 and the second rotating column 16, and a prismatic rod 24 is slidably connected in the prismatic grooves.

[0039] Specifically, the second rotating column 16 rotates. The rotating second rotating column 16 drives the first rotating column 15 on the other side to rotate through the prismatic rod 24 sliding in its prismatic groove. Since prismatic grooves are formed in the second rotating column 16 and the first rotating column 15, the first rotating column 15 can move to one side. Of course, while the first rotating column 15 is moving, it can also drive the first rotating column 15 to rotate. The rotation of the first rotating column 15 drives the turntable 9 fixed to it to rotate. Since the gears 29 rotate on the turntable 9, the gears 29 will also rotate. And the gear ring 13 meshing with a plurality of the gears 29 is fixed. Therefore, when the first rotating column 15 drives the turntable 9 to rotate, the gears 29 rotate in the opposite direction.

[0040] Please refer to Figure 1 、 Figure 2 One side of the base 1 is fixedly installed with a driving box 21. A servo motor 23 is installed in the driving box 21. A transmission belt 20 is installed between the output shaft of the servo motor 23 and the second rotating column 16.

[0041] The provided servo motor 23 operates. The output shaft of the servo motor 23 drives the second rotating column 16 to rotate through the transmission belt 20 fixed to it, and the driving box 21 fixed on one side can protect the servo motor 23 from external interference.

[0042] Wherein, the servo motor 23 is fixedly installed with a plurality of support plates for supporting it, and the support plates are fixedly installed in the driving box 21. Of course, the driving box 21 is connected to the base 1 by welding. The driving box 21 connected by welding is more stable.

[0043] Please refer to Figure 1 、 Figure 2 、 Figure 3 The base 1 is fixedly installed with a limiting frame 11. The second rotating column 16 is rotatably connected with a support frame 19 for supporting it, and the support frame 19 is fixedly installed with the limiting frame 11. A support block 14 fixedly installed with the gear ring 13 is rotatably connected to the first rotating column 15.

[0044] Specifically, the second rotating column 16 is fixed by the support frame 19, making the rotation of the second rotating column 16 more stable. The support block 14 fixes the gear ring 13 to prevent the gear ring 13 from rotating with the turntable 9. At the same time, it can also support the first rotating column 15, enabling the first rotating column 15 to rotate smoothly.

[0045] Of course, the 19 is installed with the 11 by welding, and the 19 connected by the welding method is more stable.

[0046] A pushing component is installed on the base 1. The pushing component is connected to the turntable 9, and the driving component is connected to the pushing component. The driving component drives the turntable 9 to move through the pushing component.

[0047] Please refer to Figure 2 、 Figure 3 、 Figure 4 As shown in the figure, the pushing component includes a threaded rod 12 arranged on the base 1. One end of the threaded rod 12 is rotatably connected to the mounting plate 3, and the other end of the threaded rod 12 passes through the limiting frame 11 and is fixedly installed on the output shaft of the servo motor 23. The threaded rod 12 is threadedly connected with a sliding block 17 that is threadedly connected to the limiting frame 11. A chute is formed on the sliding block 17, and a sliding rod 28 is fixedly installed in the chute. One end of the support block 14 away from the first rotating column 15 is slidably connected in the chute and sleeved on the sliding rod 28. A compression spring 18 sleeved on the sliding rod 28 is abutted between the chute and the support block 14.

[0048] When the set servo motor 23 operates, the output shaft of the servo motor 23 drives the threaded rod 12 fixed on one side to rotate. The rotating threaded rod 12 causes the sliding block 17 threadedly connected thereto to move to one side. The moving sliding block 17 drives the support block 14 thereon to move. Since the moving speed of the base 1 is slow and the enameled wire will shorten during winding, the turntable 9 will pull the support block 14 connected thereto to move to one side. The moving support block 14 pushes the abutted compression spring 18 to compress, so that the enameled wire will not break during winding.

[0049] A protection component is installed on the base 1 to prevent the broken coil from causing harm to the human body.

[0050] Please refer to Figure 1 As shown in the figure, the protection component includes a rear protection plate 8 arranged on the base 1. The rear protection plate 8 is fixedly installed with a fixing plate 22 for supporting it, and the fixing plate 22 is fixedly installed on the base 1. A front protection plate 5 is arranged on one side of the rear protection plate 8. A plurality of hinge blocks 7 are installed between the front protection plate 5 and the rear protection plate 8. A handle 6 is fixedly installed on the front protection plate 5.

[0051] Specifically, when in use, hold 6 and push the front protection plate 5 upward. The front protection plate 5 flips upward through the hinged hinge block 7. After the enameled wire is installed, push the front protection plate 5 downward so that the front protection plate 5 abuts against the rear protection plate 8, and the front protection plate 5 protects the human body.

[0052] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
