Manual adjustment is inefficient and it is difficult to ensure consistent wheel spacing, which can lead to uneven spacing between coil turns and affect the consistency of the electromagnetic performance of the ignition coil. Utility Model Content

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] like Figure 1-3As shown, a tension adjustment mechanism for an ignition coil winding device includes a base 1 with four symmetrically arranged threaded grooves 10 for easy fixed installation of the entire device on the ignition coil winding device. A support plate 2 is fixedly installed on the base 1, and a first rotating shaft 6, a second rotating shaft 8, and a third rotating shaft 9 are arranged on the support plate 2. The first rotating shaft 6 is fixedly connected to the support plate 2, and the positions of the second rotating shaft 8 and the third rotating shaft 9 on the support plate 2 are adjustable. Winding rollers 7 are rotatably mounted on the first rotating shaft 6, the second rotating shaft 8, and the third rotating shaft 9. In use, copper wire is threaded through the three winding rollers 7 to achieve the transfer of copper wire. The tension of the copper wire is adjusted by regulating the distance between the three winding rollers 7. Specifically, the support plate 2 has adjustment grooves corresponding to the positions of the second rotating shaft 8 and the third rotating shaft 9. The adjustment grooves include a first adjustment groove 3, a second adjustment groove 4, and a connecting groove 5. The first adjustment groove 3 and the second adjustment groove 4 are horizontal adjustment grooves, and the connecting groove 5 is a vertical adjustment groove, connecting the first adjustment groove 3 and the second adjustment groove 4. A movable plate 13 is slidably arranged on the side of the support plate 2. The movable plate 13 has locking grooves 14 corresponding to the first adjustment groove 3, the second adjustment groove 4, and the connecting groove 5. The second rotating shaft 8 and the third rotating shaft 9 are also mentioned. 9. Slide rods 16 are fixedly connected to the ends of the support plate 2. The slide rods 16 are slidably disposed in the first adjusting groove 3 and the locking groove 14. Locking bolts 19 are threaded on the slide rods 16 and the locking groove 14. By tightening the locking bolts 19, the moving plate 13 and the slide rods 16 are fixedly connected. A mounting bracket 12 is fixedly installed on the side of the support plate 2. An electric push rod 11 is fixedly installed on the mounting bracket 12. A positioning block 15 is fixedly installed in the middle of the moving plate 13. The output shaft of the electric push rod 11 is fixedly connected to the positioning block 15. When the electric push rod 11 is activated, the moving plate 13 is pushed to move, which drives the slide rods 16 to move. The movement of rod 16 causes the second rotating shaft 8 and the third rotating shaft 9 to move in the same direction, thereby adjusting the lateral distance between the first rotating shaft 6, the second rotating shaft 8, and the third rotating shaft 9 (in this case, the direction parallel to the base 1 and the first adjustment groove 3). When it is necessary to adjust the longitudinal distance between the first rotating shaft 6, the second rotating shaft 8, and the third rotating shaft 9, unscrew the locking bolt 19, manually slide the second rotating shaft 8 and the third rotating shaft 9 through the connecting groove 5 into the locking groove 14, and then tighten the locking bolt 19 to limit the movement of the moving plate 13 and the sliding rod 16, thereby adjusting the longitudinal distance between the first rotating shaft 6, the second rotating shaft 8, and the third rotating shaft 9.During longitudinal adjustment, in order to ensure the consistency of the lateral distance between the first rotating shaft 6, the second rotating shaft 8, and the third rotating shaft 9, the second rotating shaft 8 and the third rotating shaft 9 are moved to the same end of the second adjusting groove 4 when sliding from the first adjusting groove 3 to the second adjusting groove 4 via the connecting groove 5. After being limited, the lateral distance between the first rotating shaft 6, the second rotating shaft 8, and the third rotating shaft 9 is adjusted by the electric push rod 11. Excessive reduction of the lateral distance between the first rotating shaft 6, the second rotating shaft 8, and the third rotating shaft 9 increases the tension and causes the copper wire to bend repeatedly, increasing the risk of fatigue fracture. Therefore, a longitudinal adjustment structure is set up, and the user can choose according to the size of the ignition coil and the number of windings.

[0025] As one embodiment of this invention, a guide groove 17 is provided on the support plate 2, and an adjusting rod 18 is slidably disposed in the guide groove 17. The adjusting rod 18 is fixedly connected to the moving plate 13. The above arrangement is used to increase the stability of the movement of the moving plate 13.

[0026] Working principle:

[0027] The base plate 1 is fixedly installed on the ignition coil winding device. Copper wire is sequentially passed through the winding rollers 7 on the first rotating shaft 6, the second rotating shaft 8, and the third rotating shaft 9. The tension of the transmitted copper wire is adjusted by regulating the distance between the three winding rollers 7. The locking bolt 19 is unscrewed, and the second rotating shaft 8 and the third rotating shaft 9 are manually slid into the locking groove 14 through the connecting groove 5. Then, the locking bolt 19 is tightened to limit the movement of the moving plate 13 and the sliding rod 16, thus adjusting the longitudinal distance between the first rotating shaft 6, the second rotating shaft 8, and the third rotating shaft 9. During adjustment, in order to ensure the consistency of the lateral distance between the first rotating shaft 6, the second rotating shaft 8, and the third rotating shaft 9, when sliding from the first adjusting groove 3 to the second adjusting groove 4 through the connecting groove 5, the second rotating shaft 8 and the third rotating shaft 9 are moved to the same end of the second adjusting groove 4. The electric push rod 11 is activated, which pushes the moving plate 13 to move, thereby driving the sliding rod 16 to move. The movement of the pair of sliding rods 16 drives the second rotating shaft 8 and the third rotating shaft 9 to move in the same direction, thereby realizing the adjustment of the lateral distance between the first rotating shaft 6, the second rotating shaft 8, and the third rotating shaft 9.
