Description

Technical Field

[0001] This utility model relates to the field of reactor coil technology, and in particular to a vertical winding machine for reactors. Background Technology

[0002] A reactor, also called an inductor, is an electrical device that generates a magnetic field within a certain space when current flows through it. Therefore, all current-carrying conductors have inductance in a general sense. However, the inductance of a long, straight current-carrying conductor is relatively small, and the magnetic field it produces is not strong. Therefore, practical reactors are made by winding wire into a solenoid, called air-core reactors. Sometimes, to give the solenoid a larger inductance, an iron core is inserted inside, called an iron-core reactor. In AC power supplies using secondary inverters, filter reactors with mutual inductance are needed to improve the current-to-zero-crossing speed during AC operation and ensure smooth current commutation.

[0003] Currently, patent publication number CN201820896495.4 discloses a vertical winding structure for mutual inductance reactors. By setting the first and second helical wires as two sets of parallel wires with equal spacing, it is no longer necessary to ensure the tightness of the winding. Therefore, it is no longer necessary to wind manually and can be achieved entirely through mechanical vertical winding. This solves the problems of existing reactors where the winding structure of the inductor winding is divided into the traditional two-layer glass-coated wire winding method or the single-wire center tap winding method, which requires manual winding to ensure tight winding and has the defects of complex processing technology, high cost and poor heat dissipation.

[0004] Regarding the description of the aforementioned patent, the applicant believes that although it solves the corresponding technical problem, the technical solution still has shortcomings in other aspects, as follows:

[0005] Although the aforementioned patent sets the first and second spiral wires as two sets of parallel wires with equal spacing and winds them around the iron core, the spacing between the two wires is not easy to adjust during use, and there is no guiding mechanism during the winding process, making it difficult to quickly and evenly wind the wires onto the iron core. Therefore, we propose a vertical winding machine for reactors to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0007] Therefore, the purpose of this utility model is to provide a vertical winding machine for reactors, which can solve the problems of the existing double conductor winding spacing not being adjustable and the inconvenience of quickly and evenly winding the conductors onto the iron core.

[0008] To solve the above-mentioned technical problems, this utility model provides a vertical winding machine for reactors, which adopts the following technical solution: including,

[0026] 1. By setting up the guide component and positioning component, when winding the wire, first insert the two support plates into the inner cavities of the two slots respectively, and make the bottom of the U-shaped plate fit with the top of the fixing block. Then, rotate the round plate to move it closer to the U-shaped plate, so that part of the round plate is located at the top of the U-shaped plate and the square block is aligned with the inner cavity of the square groove. When the round plate is released, the square block moves downward and retracts into the inner cavity of the square groove under the action of the spring rebound force, and at the same time, the bottom of the round plate fits with the top of the U-shaped plate, so that the support plate can be snapped and fixed on the bracket. When winding the double wire, the two wires can be passed through the inner cavities of the two wire-threading rings respectively and wound on the iron core assembly. Then, when the servo motor is started to drive the first threaded rod to rotate, the moving block can be driven to move horizontally to the right, and the two wire-threading rings can be driven to move to the right synchronously, so that the wire can be wound quickly and evenly on the iron core.

[0027] Second, by turning the hand crank, the second threaded rod can be rotated. The rotation of the second threaded rod can cause the two movable blocks to move relative to each other or away from each other. Through the linkage of the two sliding rods, the two wire rings can be moved relative to each other or away from each other. Thus, the spacing between the two wires wound on the iron core can be adjusted, improving the flexibility of the reactor vertical winding structure. Attached Figure Description

The bottom of the support plate 301 is fitted against the bottom of the inner cavity of the slot 4001, and the outer walls of the support plate 301 are fitted against the outer walls of the inner cavity of the slot 4001. A U-shaped plate 6 is fitted and fixed to the outer walls of both support plates 301 near the bottom. The bottom of the U-shaped plate 6 is fitted against the top of the fixing block 4. Bearings are fixedly installed on both support plates 301 near the top. The support plate on the right side... A mounting bracket 302 is welded to the right side of plate 301, and a servo motor 303 is fixedly mounted on the top of the mounting bracket 302. A housing 304 is provided on the top of the iron core assembly 2 near the left side, and movable blocks 311 are attached to the inner cavity of the housing 304 near the left and right sides. A limiting slot is opened at the bottom of the housing 304, and sliding rods 310 are provided through the inner cavity of the limiting slot near the left and right sides. The top ends of the two sliding rods 310 are fixedly connected to the adjacent movable blocks 311, and wire rings 305 are fixedly connected to the bottom ends of the two sliding rods 310.

[0039] A movable block 306 is fixedly connected to the top center of the housing 304. The movable block 306 has a first threaded hole on both the left and right sides. A first threaded rod 307 is screwed into the inner cavity of the first threaded hole. The left end of the first threaded rod 307 is inserted into the inner cavity of the adjacent bearing. The right end of the first threaded rod 307 passes through the inner cavity of the adjacent bearing and is fixedly connected to the power output end of the servo motor 303. A sliding plate 308 is fixedly connected to the top of the movable block 306. A second through hole is opened on both the left and right sides of the sliding plate 308.

[0040] The positioning component 5 includes a circular plate 501, which is fitted to the top of the U-shaped plate 6. A rotating rod 502 is fixedly connected to the bottom of the circular plate 501, and the bottom end of the rotating rod 502 passes through the first through hole and extends into the inner cavity of the square groove 4003. A block 503 is fixedly connected thereto. The outer walls of the block 503 are fitted to the inner walls of the square groove 4003, and the outer walls of the block 503 are all polished.

The upper and lower ends of the spring 505 are fitted to the top of the inner cavity of the cavity 4002 and the top of the fixing ring 504, respectively.

[0041] The specific working principle is as follows: First, the symmetrical arrangement of the two supports 1 improves the stability of the iron core assembly 2. Next, the two support plates 301 are inserted into the inner cavities of the two slots 4001, and the bottoms of the two U-shaped plates 6 are respectively attached to the tops of the adjacent fixing blocks 4. Then, the circular plate 501 is rotated to the side closer to the U-shaped plate 6, so that a part of the circular plate 501 is located on the top of the U-shaped plate 6 and the square block 503 is aligned with the inner cavity of the square groove 4003. Thus, when the circular plate 501 is released, the square block 503 is subjected to the rebound force of the spring 505. Under the action of the circular plate 501, it moves downward and retracts into the inner cavity of the square groove 4003, while the bottom of the circular plate 501 is attached to the top of the U-shaped plate 6, so that the support plate 301 can be snapped and fixed on the bracket 1. When winding the double wires, the two wires can be passed through the inner cavities of the two wire loops 305 respectively and wound on the iron core assembly 2. Then, when the servo motor 303 is started to drive the first threaded rod 307 to rotate, the moving block 306 can be driven to move horizontally to the right, and the two wire loops 305 can be driven to move to the right synchronously, so that the wires can be quickly and evenly wound on the iron core.

[0042] Example 2, refer to Figure 1 and Figure 4 In this embodiment, in order to solve the problem that the spacing between existing double conductors is not easy to adjust, based on the same concept as in Embodiment 1 above, the vertical winding machine for this reactor further includes:

[0043] Both movable blocks 311 are provided with second threaded holes, and the threads of the two second threaded holes are opposite in direction. The two second threaded holes are connected to a second threaded rod 312. The left end of the second threaded rod 312 is rotatably connected to the left side of the inner cavity of the housing 304. A through hole is provided on the right side of the housing 304, and the right end of the second threaded rod 312 passes through the inner cavity of the through hole and is fixedly connected to a hand crank 313.

[0044] The specific working principle is as follows: by rotating the hand crank 313, the second threaded rod 312 can be rotated. The rotation of the second threaded rod 312 can drive the two movable blocks 311 to move relative to each other or away from each other through the opposite setting of the inner threads of the two second threaded holes. And through the linkage of the two sliding rods 310, the two wire rings 305 can be driven to move relative to each other or away from each other, thereby adjusting the spacing between the two wires wound on the iron core assembly 2, improving the flexibility of the reactor vertical winding structure.

[0045] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
