Description

Technical Field

[0001] This invention belongs to the field of inductor winding machine equipment, and particularly relates to an automatic inductor winding machine. Background Technology

[0002] A toroidal winding machine is a specialized piece of equipment used to produce toroidal coils for winding toroidal transformers, current transformers, magnetic ring inductors, and other toroidal coils. It consists of three main parts: the machine head, the clamps, and the machine base.

[0003] In existing toroidal winding machines, the three clamping rollers of the chuck are preset to hold the magnetic ring and drive it to rotate, based on the size of the magnetic ring to be wound. However, as the winding progresses, the outer diameter of the magnetic ring gradually increases, and the constant spacing of the clamping rollers interferes with the magnetic ring. This causes the enameled wire wound on the magnetic ring to shift circumferentially along the magnetic ring and also squeezes the enameled wire. Furthermore, the clamping rollers cannot stably drive the magnetic ring to rotate, resulting in uneven winding. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of unstable magnetic ring movement caused by the constant spacing of the clamping rollers in the existing winding machine, and to propose an automatic winding device for inductors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic inductor winding device, comprising a frame, a clamping mechanism mounted on the frame, the clamping mechanism comprising a clamping seat, clamping rods and a driving mechanism, the clamping seat being fixedly mounted on the frame, a sliding tube being mounted on the end of the clamping rods away from the clamping seat, a support arm being slidably mounted inside the sliding tube, a clamping roller being rotatably mounted on the end of the support arm away from the clamping rods, three clamping rods being provided, the three clamping rollers being arranged in a triangular ring to form a magnetic ring positioning area, the clamping rods being divided into a left clamping rod, a right clamping rod and a middle clamping rod, the left clamping rod and the right clamping rod being symmetrically arranged about the middle clamping rod, the middle part of the right clamping rod and the middle part of the left clamping rod being rotatably mounted on the clamping seat, the middle clamping rod being slidably mounted back and forth on the clamping seat, the driving mechanism being mounted on the clamping seat, the driving mechanism being used to drive the support arm corresponding to the left clamping rod and the support arm corresponding to the right clamping rod to slide in a direction away from the clamping seat.

[0008] As a further description of the above technical solution: the rear end of the left clamping rod and the rear end of the middle clamping rod are connected by a first connecting rod, and the rear end of the right clamping rod is connected to the middle clamping rod by a second connecting rod. The first connecting rod and the second connecting rod form a "V" shape with the opening facing the front end of the middle clamping rod.

[0009] As a further description of the above technical solution: a clamping spring is provided between the left clamping rod and the middle clamping rod, a sliding seat is provided at the lower end of the left clamping rod, a fixing rod is provided at the lower end of the middle clamping rod, one end of the fixing rod passes through the sliding seat, the clamping spring is sleeved on the fixing rod, one end of the clamping spring abuts against the sliding seat, and the other end is fixed on the fixing rod, and a drive handle is provided at the rear end of both the left clamping rod and the right clamping rod.

Limiting components are provided on the sliding tubes corresponding to the left clamping rod and the right clamping rod. A guide hole is provided on the side wall of the sliding tube, and a limiting hole is provided on the support arm. The limiting hole and the guide hole correspond to each other. The limiting component includes a limiting rod slidably disposed in the guide hole. A rotating seat is provided on the sliding tube, and a shift fork is rotatably disposed on the rotating seat. A torsion spring is provided between the rotating shaft of the shift fork and the rotating seat. A toggle shaft is provided at the tail end of the limiting rod.

[0015] (1) The automatic winding device of this application can automatically adjust the clamping position of the clamping roller according to the winding state of the magnetic ring. When the area around the magnetic ring with enameled wire is driven by the rotation of the three support rollers, and the enameled wire is about to contact the clamping roller in the direction of rotation, the position of the clamping roller is shifted by the movement of the support arm, so that the clamping roller does not interfere with the enameled wire. Then the side wall of the clamping roller contacts the arc surface formed by the enameled wire, so as to continue to drive the magnetic ring to rotate and continue to wind the wire stably in conjunction with the other two clamping rollers. This not only avoids the enameled wire from slipping along the magnetic ring, but also ensures the stability of the magnetic ring and prevents it from shifting, so that the magnetic ring can be wound evenly and stably.

[0016] (2) Through the transmission of the synchronous belt, the driven gear drives the driven arc rack to rotate synchronously, thereby accurately driving the movement of the clamping roller, and adjusting the clamping roller under the premise of ensuring the stability of the magnetic ring clamping.

[0017] (3) The adjustment hole on the swing arm can adjust the position of the driven arc rack according to the size of the magnetic ring, thereby accurately adjusting the corresponding position of the trigger block and the trigger shaft, and ensuring the accuracy of the position change of the clamping roller.

Three planetary gears (not shown in the figure) are provided on the outer periphery of the drive gear (not shown in the figure). The three planetary gears correspond one-to-one with the three clamping rollers 6. The clamping rollers 6 are connected to the planetary gears by a telescopic universal joint 8.

[0030] The rear end of the left clamping rod 3 and the rear end of the middle clamping rod 5 are connected by the first link 9. The rear end of the right clamping rod 4 and the middle clamping rod 5 are connected by the second link 10.

By pressing the shift fork arm, the shift fork head is driven away from the sliding tube 15, and the limiting rod 22 is disengaged from the limiting hole 21.

[0033] The drive mechanism is mounted on the clamping base 2. The drive mechanism is used to drive the support arm 16 corresponding to the left clamping rod 3 and the support arm 16 corresponding to the right clamping rod 4 to slide away from the clamping base 2. The drive mechanism includes a transmission gear, a driven gear 28 and a drive assembly. The transmission gear is rotatably mounted in the frame 1. The transmission gear is driven by a synchronous belt to the planetary gear corresponding to the clamping roller 6 on the middle support arm 16. The driven gear 28 is rotatably mounted on the sliding tube 15 corresponding to the middle clamping rod 5. The transmission gear and the driven gear 28 are connected by a telescopic universal joint 8. The drive assembly is used to drive the support arm 16 corresponding to the left clamping rod 3 or the right clamping rod 4 to move. The drive assembly includes a swing rod 29 rotatably mounted on the frame 1. A return torsion spring (not shown in the figure) is provided at the rotation axis of the swing rod 29. A connecting shaft 30 is provided at the end of the swing rod 29. An adjustment hole 31 is provided on the swing rod 29. A locking bolt 32 is provided at the upper end of the connecting shaft 30. The locking bolt 32 passes through the adjustment hole 31 and is threaded into the connecting shaft 30. The lower end of the connecting shaft 30 is provided with a driven arc-shaped rack 33, which meshes with the driven gear 28. The driven arc-shaped rack 33 is provided with a trigger block 34 corresponding to the trigger shaft 27. The driven arc-shaped rack 33 includes a toothless part and a toothed part.

[0034] Specifically, the rotation axis of the swing arm 29 corresponding to the left clamping rod 3 is coaxial with the moving axis of the left clamping rod 3, and the axis of the arc of the driven arc rack 33 installed on the swing arm 29 corresponding to the left clamping rod 3 coincides with the rotation axis of the swing arm 29; similarly, the rotation axis of the swing arm 29 corresponding to the right clamping rod 4 is coaxial with the moving axis of the right clamping rod 4, and the axis of the arc of the driven arc rack 33 installed on the swing arm 29 corresponding to the right clamping rod 4 coincides with the rotation axis of the swing arm 29; the two driven arc racks 33 are arranged vertically.

[0035] This application also includes a head plate (not shown in the figure) disposed on the frame 1. The head plate is provided with a wire supply system and a wire threading system corresponding to the clamping mechanism. Both the wire supply system and the wire threading system are existing technologies.

[0036] Working principle: When threading the magnetic ring 01, first install the magnetic ring 01 in the positioning area formed by the three clamping rollers 6 arranged in a triangular ring. During installation, drive the two drive handles 14 to move the front ends of the left clamping rod 3 and the right clamping rod 4 away from each other, while driving the middle clamping rod 5 to move, placing the magnetic ring 01 between the three clamping rollers 6. Then release the pressure on the drive handles 14. Under the force of the clamping spring 11, the magnetic ring 01 is fixed between the three clamping rollers 6, and then threading is performed.

[0037] Before threading, the limiting hole 21 on the support arm 16 corresponding to the left clamping rod 3 corresponds to the guide hole 20 on the sliding tube 15, the limiting rod 22 is located in the limiting hole 21, the adjusting spring 19 in the sliding tube 15 is in a compressed state, and the swing rod 29 corresponding to the left clamping rod 3 rotates to the end of the swing rod 29 that is far away from the left clamping rod 3.

[0038] The limiting hole 21 on the support arm 16 corresponding to the right clamping rod 4 corresponds to the guide hole 20 on the sliding tube 15. The limiting rod 22 is located in the limiting hole 21. The adjusting spring 19 in the sliding tube 15 is in a compressed state. The swing rod 29 corresponding to the right clamping rod 4 rotates to the end of the swing rod 29 that is close to the right clamping rod 4.

[0039] During the threading process, the threading system and the threading system work simultaneously. At the same time, the drive motor starts, causing the three clamping rollers 6 to rotate. In this embodiment, the magnetic ring 01 rotates counterclockwise, and the corresponding three clamping rollers 6 rotate clockwise. Simultaneously, the driven gear 28 rotates clockwise, and the driven arc-shaped rack 33 meshing with the driven gear 28 moves. The left end of the driven arc-shaped rack 33 corresponding to the left clamping rod 3 moves toward the left clamping rod 3, and the right end of the driven arc-shaped rack 33 corresponding to the right clamping rod 4 moves away from the right clamping rod 4.

[0040] When the magnetic ring 01 wound with enameled wire is about to contact the clamping roller 6 corresponding to the left clamping rod 3, the driven arc-shaped rack 33 corresponding to the left clamping rod 3 moves under the action of the driven gear 28, causing the trigger block 34 on the driven arc-shaped rack 33 to drive the trigger shaft 27, causing the limiting rod 22 to slide out of the limiting hole 21. At this time, under the action of the adjusting spring 19, the support shaft moves away from the sliding tube 15, causing the clamping roller 6 to extend outward. The clamping roller 6 then adapts to the outer periphery corresponding to the enameled wire, so that the clamping roller 6 does not interfere with the enameled wire. As the driven gear 28 continues to rotate, the driven gear 28 corresponds to the toothless part of the driven arc-shaped rack 33, and therefore no longer drives the driven arc-shaped rack 33 corresponding to the left clamping rod 3 to move. The same working principle of the driven arc rack 33 corresponding to the right clamping rod 4 drives the support arm 16 to move, so that when the enameled wire is about to contact the clamping roller 6 corresponding to the right clamping rod 4, the clamping roller 6 moves so as not to interfere with the enameled wire, ensuring the uniformity and stability of the winding.

[0041] It should be noted that the adjusting spring 19 provided between the support arm 16 corresponding to the middle clamping rod 5 and the sliding tube 15 can adaptively adapt to the magnetic ring 01 with enameled wire wound around it, so that no interference occurs.

[0042] After the enameled wire is completely wound around the magnetic ring 01, stop winding and release the clamp on the magnetic ring 01 by driving the drive handle 14. At the same time, the swing arm 29 and the driven arc rack 33 are reset under the action of the reset torsion spring. Then, manually press the support arm 16 toward the sliding tube 15 so that the limit rod 22 is matched with the limit hole 21.

[0043] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of the present invention within the scope of the technology disclosed in the present invention, and all such substitutions or changes should be covered within the scope of protection of the present invention.
