Description
Technical Field
[0001] This utility model relates to the field of stator processing technology, and more specifically, to a tension adjustment mechanism for a stator winding machine. Background Technology
[0002] In the stator winding process of motors, precise control of wire tension is a key factor in ensuring winding quality. Traditional winding machines typically use mechanical tensioners or simple counterweight devices to adjust wire tension, which suffers from problems such as low adjustment accuracy and slow response speed.
[0003] While existing mechanical tensioners are simple in structure, they cannot monitor tension changes in real time, and are prone to wire breakage due to excessive tension or loose winding due to insufficient tension. On the other hand, electronic tension control systems, although highly accurate, are complex in structure and expensive, which is not conducive to their widespread application in ordinary winding equipment. In addition, in existing technologies, the tension adjustment mechanism is often set separately from the winding mechanism, resulting in large equipment space occupation, inconvenient operation, and difficulty in meeting the higher requirements of modern motor production for winding efficiency and quality. Therefore, in order to address the above technical problems, a tension adjustment mechanism for a stator winding machine is proposed here. Utility Model Content
[0004] The purpose of this invention is to provide a tension adjustment mechanism for a stator winding machine. By adjusting the position of the wire frame through the slide groove, the wire path length can be changed, thereby achieving rapid tension adjustment. Combined with a tension sensor and an elastic connection structure, tension data is monitored and fed back in real time to ensure that the winding tightness is controllable. The linkage between mechanical adjustment and intelligent detection not only improves the winding quality but also avoids wire breakage. The operation is simple and safe.
[0005] This utility model is achieved through the following technical solution: A tension adjustment mechanism for a stator winding machine includes: The motherboard has two sets of symmetrically arranged rotating shafts rotatably connected to one side, and a winding disc is fixedly connected to the outside of the rotating shafts. A slide groove is formed on the outside of the motherboard. A slider is slidably connected to the inside of the slide groove. A wire threading mechanism is installed on one side of the slider, and a second slide plate is fixedly connected to the other side of the slider. A positioning mechanism is installed between the second slide plate and the motherboard. A protrusion is fixedly connected to the outside of the second slide plate, and a hanging ring is fixedly connected to the upper side of the protrusion; A tension sensor is fixedly connected to the outside of the main board and is located directly above the hanging ring. A sensing plate is fixedly connected to the bottom of the tension sensor, and a tension monitoring mechanism is installed between the sensing plate and the hanging ring. Preferably, the threading mechanism includes a first sliding plate, a connecting rod, and a thread guide frame. The first sliding plate is fixedly connected to one side of the slider, the connecting rod is fixedly connected to the outside of the first sliding plate, and the thread guide frame is fixedly connected to the end of the connecting rod, and the thread guide frame is a hollow structure. Preferably, the positioning mechanism includes positioning holes and positioning bolts. The positioning holes are located on the outside of the main board, and there are several groups of positioning holes arranged symmetrically. The positioning holes are installed on both sides of the slide groove. The positioning bolts are threadedly connected between the second slide plate and the positioning holes, and there are four groups of positioning bolts arranged in an array. Preferably, the tension monitoring mechanism includes a tension spring, a connecting block, and a hook. The tension spring is fixedly connected to the bottom of the sensing sheet, the connecting block is fixedly connected to the bottom end of the tension spring, and the hook is fixedly connected to the lower side of the connecting block.

[0006] The technical solution of this utility model has at least the following beneficial effects: The tension adjustment mechanism of this stator winding machine, through a sliding groove and adjustable wire guide frame structure, allows the operator to quickly adjust the wire path length, achieving precise tension adjustment and significantly improving winding tightness and consistency. The cooperation between the tension sensor and the elastic connection component can provide real-time feedback of tension data, avoiding the blindness of traditional mechanical adjustment and effectively preventing the wire from breaking due to excessive tightness or becoming too loose. The synergistic effect of mechanical adjustment and intelligent monitoring simplifies the operation process and ensures stable winding quality. The overall structure is compact and reasonable, achieving visualized tension control without increasing the size of the equipment. It greatly improves winding efficiency while reducing the scrap rate, making it particularly suitable for the production of motor stators with high winding precision requirements.

Detailed Implementation
[0008] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0009] Example: Please see Figures 1-7 This application discloses a tension adjustment mechanism for a stator winding machine, comprising a main board 1, a slide groove 4, a protrusion 12, and a tension sensor 14. Two sets of symmetrically arranged rotating shafts 2 are rotatably connected to one side of the main board 1, and a winding disc 3 is fixedly connected to the outside of the rotating shafts 2. The slide groove 4 is located outside the main board 1, and a slider 5 is slidably connected to the inside of the slide groove 4. A threading mechanism is installed on one side of the slider 5, and a second sliding plate 9 is fixedly connected to the other side of the slider 5. A positioning mechanism is installed between the second sliding plate 9 and the main board 1. The protrusion 12 is fixedly connected to the outside of the second sliding plate 9, and a hanging ring 13 is fixedly connected to the upper side of the protrusion 12. The tension sensor 14 is fixedly connected to the outside of the main board 1, and the tension sensor 14 is located directly above the hanging ring 13. A sensing plate 15 is fixedly connected to the bottom of the tension sensor 14, and a tension monitoring mechanism is installed between the sensing plate 15 and the hanging ring 13. The threading mechanism includes a first slide plate 6, a connecting rod 7, and a thread guide frame 8. The first slide plate 6 is fixedly connected to one side of the slider 5, the connecting rod 7 is fixedly connected to the outside of the first slide plate 6, and the thread guide frame 8 is fixedly connected to the end of the connecting rod 7. The thread guide frame 8 is a hollow structure, which can guide the wire to move smoothly along the set path. The positioning mechanism includes positioning holes 10 and positioning bolts 11. The positioning holes 10 are located on the outside of the main board 1, and there are several sets of positioning holes 10 arranged symmetrically. The positioning holes 10 are installed on both sides of the slide groove 4. The positioning bolts 11 are threaded between the second slide plate 9 and the positioning holes 10, and there are four sets of positioning bolts 11 arranged in an array. The adjustment position of the slider 5 can be quickly locked by the positioning bolts 11. The tension monitoring mechanism includes a tension spring 16, a connecting block 17, and a hook 18. The tension spring 16 is fixedly connected to the bottom of the sensing plate 15, the connecting block 17 is fixedly connected to the bottom end of the tension spring 16, and the hook 18 is fixedly connected to the lower side of the connecting block 17. The deformation of the tension spring 16 can reflect the change in wire tension in real time. The hook 18 and the hanging ring 13 are interlocked, and this detachable connection method facilitates maintenance and replacement of parts. Connecting plates 19 are fixedly connected to both the upper and lower sides of the motherboard 1, and the connecting plates 19 provide a stable mounting base for the overall structure. The connecting plate 19 has four sets of connecting holes 20 arranged in an array on its exterior. This mechanism can be assembled onto a stator winding machine through the connecting holes 20.
[0010] The working principle of the tension adjustment mechanism of the stator winding machine based on the embodiment is as follows: the wire is first wound onto the winding reel 3 on one side of the main board 1, then passes through the wire guide frame 8 on one side of the slider 5, and finally extends to the winding reel 3 on the other side to complete the winding path. When it is necessary to adjust the wire tension, the operator loosens the positioning bolt 11 to release the fixed constraint between the second slide plate 9 and the main board 1. At this time, the slider 5 can slide freely along the slide groove 4. By manually pushing the slider 5 downward, the first slide plate 6 and the wire guide frame 8 are moved downward as a whole, so that the distance between the wire guide frame 8 and the two sets of winding reels 3 increases. The wire tension increases due to the extension of the path. After adjusting to the target tension, the second slide plate 9 is aligned with the positioning hole 10 on the main board 1, and the positioning bolt 11 is tightened again to complete the fixation, thereby achieving fast and accurate tension adjustment and ensuring that the stator winding is tight and uniform. Meanwhile, the downward movement of slider 5 drives the protrusion 12 and its top hanging ring 13 to descend synchronously through the second sliding plate 9. The hanging ring 13 pulls down the hook 18 connected to the tension sensor 14, forcing the tension spring 16 to stretch and produce elastic deformation. At this time, the tension sensor 14 collects the tension data of the tension spring 16 in real time through the sensing plate 15, converts it into a visualized tension value and feeds it back to the external monitoring equipment. The operator can dynamically monitor the wire tension accordingly to prevent wire breakage due to excessive tension or insufficient tension from affecting the winding quality. Through the synergistic effect of mechanical adjustment and electronic monitoring, the winding efficiency is improved and intelligent protection of tension control is realized, which significantly optimizes the process stability and equipment reliability of stator winding.
