Description

Technical Field

[0001] This utility model relates to the technical field of hollow reactor production equipment, specifically to a hollow reactor winding fixture. Background Technology

[0002] Air-core reactors are important reactive power compensation devices in power systems, typically consisting of coils, insulating cylinders, air duct supports, and insulating support frames at both ends. For example, the air-core reactor disclosed in the applicant's patent CN220543697U has a support frame composed of a first insulating plate, a second insulating plate, and several tie bolts. During manufacturing, the insulating cylinder is first fixed between the two insulating plates, ensuring that the insulating cylinder and the through holes on the insulating plates are coaxial, to assemble the reactor structure. Subsequently, the coil is wound on the outside of the insulating cylinder, and during the winding process, air duct supports are alternately placed between the coil layers to form heat dissipation channels.

[0003] Currently, the winding process mainly relies on traditional manual operation. Specifically, after each layer of coil is wound, operators must manually measure, determine, and place multiple air channel support bars. This production method has significant drawbacks: First, ensuring the vertical alignment and consistent position of the support bars between layers requires a significant amount of time for manual measurement and positioning, severely impacting overall winding efficiency. Second, manual operation inevitably introduces placement errors, easily leading to uneven support bars and inconsistent spacing, affecting not only the product's aesthetics but also potentially negatively impacting the reactor's heat dissipation and electrical performance. Therefore, the production of hollow reactors in existing technologies suffers from low winding efficiency, high labor costs, and insufficient stability in support bar placement quality. A specialized tooling is urgently needed to achieve rapid and accurate positioning of the support bars, simplify the assembly process, and thereby improve production automation and product consistency. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a hollow reactor winding fixture that can simplify the assembly process of hollow reactors, improve the level of production automation, and enhance product consistency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hollow reactor winding fixture, comprising a positioning component, a support component, and a winding machine for providing rotational drive; the positioning component includes a left clamp and a connecting plate, the left clamp includes a clamping plate and a support bar positioning component, the clamping plate having a central hole in its center; the support bar positioning component is fixedly disposed on the inner end of the clamping plate and coaxially arranged with the central hole; the support bar positioning component has multiple guide grooves radially identical to the central hole; the connecting plate is fixedly installed on the outer end of the clamping plate for fixed connection with the rotational output end of the winding machine; the support component includes a right clamp, a fixing block, and a fixing shaft, the right clamp having the same structure as the left clamp and facing each other; the fixing block is fixedly disposed on the outer end of the right clamp; the fixing block has a shaft hole; the tail end of the fixing shaft is fixedly connected to the fixed end of the winding machine, and the head end has a tapered structure for rotating engagement with the shaft hole.

[0007] Preferably, the support bar positioning component consists of multiple guide rods fixed to the clamp plate and distributed around the central hole axis, with the length direction of the guide rods being the same as the radial direction of the central hole; the guide grooves are correspondingly arranged with the guide rods.

[0008] Preferably, the winding machine includes a base, a left support seat mounted on the base, a turntable mounted on the left support seat, a right support seat slidably mounted on the base and facing the left support seat, and a connecting seat fixedly mounted on the right support seat; the connecting plate is fixedly connected to the turntable; and the tail end of the fixed shaft is fixedly connected to the connecting seat.

[0009] Preferably, the reactor includes an airway support bar; the width of the guide groove is adapted to the outer diameter of the airway support bar.

Detailed Implementation

[0018] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice this utility model. Although this utility model has been described in conjunction with its preferred embodiments, these embodiments are merely illustrative and not intended to limit the scope of this utility model.

[0019] See Figure 1-5 In one embodiment of this utility model, a hollow reactor winding fixture includes: a positioning component, a support component, and a winding machine 6. During coil winding, the reactor structural components can be movably mounted on the winding machine 6 via the positioning component and the support component. Through the cooperation of the positioning component and the support component, the coil and the support bar can be alternately wound on the outside of the insulating cylinder, solving the problem of support bar placement deviation and improving coil winding efficiency.

[0020] The winding machine 6 includes a base 61, a left support seat 62 mounted on the base 61, a turntable 63 mounted on the left support seat 62, a right support seat 64 slidably mounted on the base 61 and opposite to the left support seat 62, and a connecting seat 65 fixedly mounted on the right support seat 64; the distance between the right support seat 64 and the left support seat 62 can be adjusted by external drive to adapt to the winding needs of reactor structural components of different lengths.

[0021] The positioning component includes a left clamp 1 and a connecting plate 3. The left clamp 1 includes a clamp plate 11 and a support positioning component. The clamp plate 11 has a through central hole 111 in the middle. Multiple connecting holes 112 are also provided on the outer side of the central hole 111 on the clamp plate 11. The connecting holes 112 are used to provide installation space for the tie bolts required for reactor assembly. The outer edge dimension of the clamp plate 11 is the same as the outer edge dimension of the insulating plate, so that the clamp plate 11 coincides with the insulating plate to complete the precise positioning before winding. The support bar positioning component is a ring structure, with its inner diameter matching the outer diameter of the insulating cylinder and its outer diameter matching the inner diameter of the through hole in the insulating plate. The support bar positioning component is fixedly mounted on one side of the clamping plate 11 and is coaxially arranged with the center hole 111. During winding, the outer circumference of the insulating cylinder abuts against the inner ring of the support bar positioning component, while the outer ring of the support bar positioning component abuts against the inner ring of the through hole in the insulating plate. The support bar positioning component can not only provide a support point for the reactor structure, but also allow the reactor structure to adjust its posture under the support of the support bar positioning component, making it convenient for the insulating plate to overlap with the clamping plate 11.

[0022] In this embodiment, the support bar positioning component consists of multiple guide rods 12 fixed on the clamping plate 11 and distributed around the central hole 111. The length direction of the guide rods 12 is the same as the radial direction of the central hole 111. A guide groove is formed on the guide rod 12 along its length direction, and the width of the guide groove is adapted to the outer diameter of the support bar.

[0023] The connecting plate 3 has a U-shaped structure and is fixed to one side of the guide rod 12 on the clamping plate 11 by welding. The clamping plate 11 is fixedly installed on the turntable 63 through the connecting plate 3. The positioning component can rotate circumferentially under the support of the turntable 63.

[0024] The support includes a right clamp 2, a fixing block 4, and a fixing shaft 5. The right clamp 2 has the same structure as the left clamp 1, and the two are arranged facing each other at the same horizontal height, with the support bar positioning members located on the inner side. During winding, both ends of the reactor structure are supported by the support bar positioning members in the left and right clamps, ensuring that it remains coaxial with the turntable 63.

[0025] The fixing block 4 is fixedly mounted on the right clamp 2 at the end away from the left clamp 1. The fixing block 4 has a shaft hole 41. The tail end of the fixing shaft 5 is fixedly connected to the connecting seat 65. The head end of the fixing shaft 5 has a tapered structure and rotates with the shaft hole 41. During winding, the head end of the fixing shaft 5 is embedded in the shaft hole 41. By adjusting the position of the right support seat 64, the reactor structure is securely clamped between the left and right clamps. At this time, the two clamping plates 11 overlap with the corresponding insulating plates, the guide rods 12 at both ends correspond one-to-one, and the support bars can be accurately installed along the guide grooves of the guide rods 12 at both ends.

[0026] Working principle explanation: This winding fixture uses guide rods 12 in the left and right clamps to radially limit and circumferentially position the air duct support bars, ensuring consistent positioning of the multi-level support bars. During winding, the turntable 63 rotates the reactor structure, and the operator places the support bars sequentially along the guide groove and winds the coil. The right support seat 64 is adjustable to accommodate different product lengths. The tapered end of the fixed shaft 5 provides axial support and free rotation, ensuring a stable and continuous winding process. This structure effectively reduces manual measurement and adjustment time, improving winding accuracy and production efficiency.

[0027] Through this technical solution, the hollow reactor winding fixture proposed in this application, by setting up left and right clamps consisting of clamping plates and guide rods with guide grooves, and cooperating with the turntable and sliding support on the winding machine, achieves rapid centering and clamping of reactor structural components. The guide grooves on the guide rods, whose width matches the outer diameter of the support bars, provide precise guidance and positioning for the placement operation, effectively eliminating deviations caused by manual measurement and placement, ensuring consistent alignment of support bars between layers, and significantly improving winding neatness and product quality. At the same time, this fixture simplifies the support bar placement process, greatly reduces the time spent on repeated measurements and adjustments, improves winding efficiency, and saves labor costs. Furthermore, the cooperation between the sliding right support and the tapered fixed shaft allows for quick adaptation and clamping of reactor structural components of different lengths, enhancing the fixture's versatility, simplifying assembly operations, and reducing labor intensity.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
