The adjustment process takes a long time and the actual operation is cumbersome. When it is necessary to quickly complete the winding work of iron cores of different sizes, it is necessary to repeat such adjustment operations frequently. Therefore, frequent replacement of annular iron cores of different sizes may affect the working efficiency of the winding machine.

[0005] Therefore, the utility model provides a ring-shaped coil core fixing device for a winding machine. Utility Model Content

[0006] The purpose of the utility model is to provide a toroidal coil core fixing device for a winding machine to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme: a toroidal coil core fixing device for a winding machine, comprising a base and an annular winding machine fixedly installed on the top of the base, a motor is fixedly installed on one side of the top of the base, and a first fixed shaft is fixedly connected to the output end of the motor, and also includes

[0008] The driving mechanism located at the top of the base is configured to control the electric telescopic rod fixed inside the base so that the toothed plate fixedly connected to the telescopic end of the electric telescopic rod drives the first gears on both sides to rotate, drives the second gear coaxial with the first gear to rotate, and thus drives the third gear meshing with the second gear to rotate;

[0009] An adjustment mechanism is configured to adapt to cores of different sizes by changing the distance between two adjustment rods symmetrically arranged on both sides of the toroidal winding machine under the action of the driving mechanism;

[0010] The fourth gear is arranged to be fixed at the bottom of the adjusting rod. When the third gear rotates, it rotates on the arc-shaped teeth meshing with the third gear, so that the two adjusting rods move in a curved path.

[0012] Preferably, the adjustment mechanism also includes a first arc-shaped groove opened on the top of the base, a second arc-shaped groove is opened at the bottom of the first arc-shaped groove, the teeth are fixedly connected to the outer ring side wall of the second arc-shaped groove, and the first arc-shaped groove is connected to the second arc-shaped groove.

[0016] Beneficial effects:

[0017] (1) The utility model discloses a ring-shaped coil core fixing device for a winding machine. The electric telescopic rod is extended to push the tooth plate to move, so that the second gear drives the third gear to rotate, thereby rotating the adjustment rod fixedly connected to the third gear. When the adjustment rod rotates, the fourth gear at the bottom thereof rotates on the teeth in the second arc groove. Therefore, the adjustment rod slides in the first arc groove while rotating, so that the two adjustment rods move away from each other to facilitate the installation of a ring-shaped core of a larger size. The electric telescopic rod is controlled to retract according to the size of the core. When the rotating cylinder on the adjustment rod is in contact with the core, the electric telescopic rod stops retracting and the position of the adjustment rod is fixed, which is convenient for adjustment and fixation.

[0018] (2) The utility model discloses a ring-shaped coil core fixing device for a winding machine. When the position of the rotating cylinder on the first fixed axis remains unchanged, the two adjusting rods move in an arc shape. When the distance between the two adjusting rods increases, the vertical distance between the adjusting rods and the first fixed axis also increases. Therefore, when fixing a ring-shaped core of a larger size, the core can be fixed stably to avoid the three rotating cylinders being too close to each other, which would cause the core to shake when the winding machine is working.

[0025] In order to more clearly illustrate the technical solutions in the embodiments of the utility model or the prior art, the utility model will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the utility model, but does not constitute a limitation of the utility model.

[0026] Example:

[0027] like Figure 1-Figure 5 The illustrated embodiment of a toroidal coil core fixing device for a winding machine comprises a base 1 and an toroidal winding machine fixedly mounted on the top of the base 1, wherein a motor is fixedly mounted on one side of the top of the base 1, and a first fixed shaft 2 is fixedly connected to the output end of the motor, and further comprises a driving mechanism 4 located at the top of the base 1, which is configured to control an electric telescopic rod 42 fixed inside the base 1 so that a toothed plate 43 fixedly connected to the telescopic end of the electric telescopic rod 42 drives the first gears 44 on both sides to rotate, and drives the second gear 46 coaxial with the first gear 44 to rotate, thereby rotating a third gear 52 meshing with the second gear 46; an adjusting mechanism 5, which is configured to adapt to cores of different sizes by changing the distance between two adjusting rods 51 symmetrically arranged on both sides of the toroidal winding machine under the action of the driving mechanism 4; a fourth gear 56, which is configured to be fixed to the bottom of the adjusting rod 51, and when the third gear 52 rotates, it rotates on the arc-shaped teeth 55 meshing with it, thereby causing the two adjusting rods 51 to move in a curved path.

[0028] In this embodiment, the first fixed shaft 2 and the rotating cylinders 3 on the two adjusting rods 51 are both against the annular iron core to fix it. When a larger-sized iron core needs to be replaced, the electric telescopic rod 42 is controlled to extend, pushing the toothed plate 43 toward the first fixed shaft 2, driving the first gear 44 meshing with the toothed plate 43 to rotate, so that the second gear 46 drives the third gear 52 to rotate, thereby causing the adjusting rod 51 to move in the first arc groove 53, and the distance between the two adjusting rods 51 increases. After placing the large-sized iron core and determining its position, the electric telescopic rod 42 is controlled to retract. When the rotating cylinder 3 on the adjusting rod 51 is against the iron core, the electric telescopic rod 42 stops retracting, the position of the adjusting rod 51 stops moving, and the iron core is fixed.

[0029] like Figure 2-Figure 5As shown, the driving mechanism 4 also includes a mounting groove 41 opened inside the base 1, and the side of the mounting groove 41 away from the first fixed axis 2 is fixedly connected to the electric telescopic rod 42, and the second fixed axis 45 is respectively provided on both sides of the tooth plate 43, and the second fixed axis 45 is rotatably connected to the bottom of the mounting groove 41, and the first gear 44 is fixedly connected to the second fixed axis 45. The two sides of the tooth plate 43 are meshed with the first gear 44, and the tooth plate 43 is slidably connected to the mounting groove 41, and the second gear 46 is fixedly connected to the top of the second fixed axis 45; the adjustment mechanism 5 also includes a first arc opened at the top of the base 1 shaped groove 53, a second arc groove 54 is opened at the bottom of the first arc groove 53, the tooth 55 is fixedly connected to the outer ring side wall of the second arc groove 54, and the first arc groove 53 is communicated with the second arc groove 54; the third gear 52 is fixedly connected to the adjusting rod 51, the adjusting rod 51 passes through the first arc groove 53, and the first arc groove 53 cooperates with the adjusting rod 51; a rotating cylinder 3 is provided on the top of the first fixed shaft 2 and the top of the adjusting rod 51, the rotating cylinder 3 on the top of the first fixed shaft 2 is fixedly connected to the first fixed shaft 2, and the rotating cylinder 3 on the top of the adjusting rod 51 is rotatably connected to the adjusting rod 51.

[0030] When the third gear 52 is rotated, the adjusting rod 51 fixedly connected thereto is driven to rotate, so that the fourth gear 56 at the bottom of the adjusting rod 51 rotates synchronously. The fourth gear 56 is engaged with the teeth 55 in the second arc groove 54. Therefore, when the adjusting rod 51 rotates, it will slide along the trajectory of the first arc groove 53 under the action of the fourth gear 56. After the position of the large-size iron core is determined, the electric telescopic rod 42 is controlled to retract. When the rotating cylinders 3 on the two adjusting rods 51 abut against the iron core, the electric telescopic rod 42 stops retracting, and the position of the adjusting rod 51 is fixed.

[0031] like Figure 2 and Figure 4 As shown, the first arc groove 53, the second arc groove 54 and the second fixed shaft 45 all have the same center.

[0032] In this embodiment, when the third gear 52 rotates, it drives the adjusting rod 51 to rotate, so that the fourth gear 56 rotates on the teeth 55 in the second arc groove 54. Therefore, while the adjusting rod 51 rotates, it also slides in the first arc groove 53 with the second fixed axis 45 as the center, and moves in an arc path. After the distance between the two adjusting rods 51 increases, the vertical distance between the adjusting rod 51 and the first fixed axis 2 also increases. Compared with the adjusting rods 51 moving away from each other in a straight line, it can make it more stable when fixing a large-sized annular iron core.

[0033] Working principle: When in use, the iron core is fixed by three rotating cylinders 3. When a large-sized iron core needs to be replaced, the electric telescopic rod 42 is controlled to extend, so that the electric telescopic rod 42 pushes the toothed plate 43 to move. When the toothed plate 43 moves, it drives the first gears 44 on both sides to rotate, thereby driving the second gear 46 coaxial with the first gear 44 to rotate. When the second gear 46 rotates, it drives the third gear 52 and the adjusting rod 51 fixedly connected to the third gear 52 to rotate. The fourth gear 56 fixedly connected to the bottom of the adjusting rod 51 is driven by the adjusting rod 51 to rotate in the second arc groove 54. The adjusting rod 51 rotates on the rack 55 inside, so that the adjusting rod 51 slides in the first arc groove 53 while rotating itself, thereby increasing the distance between the two adjusting rods 51, and at the same time, the vertical distance between the adjusting rod 51 and the first fixed axis 2 is also increasing. After determining the position of the large-sized iron core, the electric telescopic rod 42 contracts. When the rotating cylinder 3 on the adjusting rod 51 abuts against the iron core, the electric telescopic rod 42 stops working, so that the position of the adjusting rod 51 is fixed, avoiding the three rotating cylinders 3 from being too close. When fixing the large-sized iron core, it can remain stable when winding on the winding machine.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
