Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a tension attenuation stabilizing mechanism for a stator winding machine. Background Art

[0002] The stator is the stationary part of an electric motor or generator. Compared with the rotor, the main function of the stator is to generate a rotating magnetic field and interact with the rotor to drive the rotation of the motor or realize the power generation function of the generator. The stator is generally composed of a base, a stator core and a stator winding.

[0003] During the stator winding process, in order to prevent the enameled wire from being too tensile or too weak, resulting in uneven winding, looseness or breakage, a tension attenuation stabilization mechanism is required to stabilize the tension of the enameled wire. However, in actual application, the applicant has found that the existing stator winding tension stabilization mechanism usually adopts a single-point support tensioning method. Although it can achieve the tension stability of the enameled wire, the single-point force causes the enameled wire to float too much, and a longer tensioning distance is required to meet the tensioning requirements, which has the disadvantage of low tensioning effect. For this reason, the present application proposes a tension attenuation stabilization mechanism for a stator winding machine. Utility Model Content

[0004] The utility model aims to provide a tension attenuation stabilizing mechanism for a stator winding machine, which adopts a double-point tensioning method, can prevent the tension of the enameled wire from being too small, and can also prevent the tension of the enameled wire from being too large, and has a good tensioning effect on the enameled wire.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A tension attenuation stabilization mechanism for a stator winding machine comprises a mounting arm, a pair of tensioning arms are rotatably mounted on the top of the mounting arm, and tensioning wheel groups are mounted at both ends of the pair of tensioning arms; a slider is movably arranged on one side of the mounting arm, a thrust arm is rotatably mounted between the slider and one end of the tensioning arm, and a driving mechanism for driving the slider to rise and fall is arranged on the mounting arm.

[0007] Preferably, the driving mechanism includes a pair of fixed plates fixed on the side walls of the mounting arm, a screw rod vertically rotatably mounted between the pair of fixed plates, and a driving motor mounted on one of the fixed plates, the driving shaft of the driving motor is coaxially connected to the screw rod, and the slider is threadedly sleeved on the screw rod.

[0008] Preferably, the slider is configured as a rectangular structure, and the slider is slidably fitted with the side wall of the mounting arm.

[0009] Preferably, the tensioning wheel assembly comprises a guide pulley rotatably mounted between a pair of ends of the tensioning arms, and a pair of guide pulleys are arranged side by side.

[0010] Preferably, a groove is provided on the surface of the guide pulley, and the groove is in an arc shape.

[0011] Preferably, the thrust arm includes a first connecting arm, an insertion rod and a second connecting arm, one end of the first connecting arm is rotatably connected to the slider, the insertion rod is movably arranged at an end of the first connecting arm away from the slider, the second connecting arm is fixed to an end of the insertion rod extending out of the first connecting arm, and the second connecting arm is rotatably connected to one end of the tensioning arm, a stopper is fixed to the end of the insertion rod extending into the first connecting arm, and a spring is arranged between the stopper and the end wall of the first connecting arm facing the slider.

[0012] Preferably, a pair of mounting plates are symmetrically arranged at the top end of the mounting arm, and the middle positions of the pair of tensioning arms are rotatably mounted on the opposite sides of the pair of mounting plates.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model uses a tensioning wheel group arranged at both ends of the tensioning arm and a thrust arm connected to one end of the slider and the tensioning arm. The enameled wire passes through two pairs of guide pulleys in the two tensioning wheel groups. The driving motor is started to drive the screw rod to rotate, drive the slider to rise and fall, and the slider drives the thrust arm to rotate and move, forcing the pair of tensioning arms to rotate a certain angle. Thus, the two pairs of guide pulleys at both ends of the pair of tensioning arms can tension the enameled wire to ensure that the coil wound by the enameled wire is of appropriate tightness and full tightness, thereby improving the quality of the coil. In addition, the tensioning method of rotating and tilting the tensioning arm and the double-point tensioning method are adopted, and a better tensioning effect can be obtained under a limited contact distance of the enameled wire. At the same time, it is suitable for bidirectional transportation of the enameled wire and is more flexible.

[0015] The utility model forms a thrust arm through a first connecting arm, an insertion rod and a second connecting arm, and a spring for elastically supporting the insertion rod is arranged in the first connecting arm. Therefore, when the tensioning arm is forced to rotate to tension the enameled wire, a certain elastic buffer space is provided to avoid the enameled wire from breaking due to excessive tension.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] In the description of the present utility model, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the present utility model. The following is a detailed description of various embodiments of the present utility model in conjunction with the drawings.

[0023] Example

[0024] See also Figures 1 to 4 , the utility model preferably provides a technical solution:

[0025] The cam 4 is provided with a plurality of tensioning wheels 3, and the tensioning wheels 3 are provided at two ends of the cam 4.

[0026] In this embodiment, a pair of mounting plates 18 are symmetrically arranged at the top of the mounting arm 1, and the middle positions of the pair of tensioning arms 2 are rotatably mounted on the opposite sides of the pair of mounting plates 18, which is beneficial to the transportation of the enameled wire.

[0027] As a preferred implementation manner of this embodiment, the driving mechanism 6 includes a pair of fixed plates 8 fixed on the side walls of the mounting arm 1, a screw rod 9 vertically rotatably installed between the pair of fixed plates 8, and a driving motor 10 installed on one of the fixed plates 8. The driving shaft of the driving motor 10 is coaxially connected to the screw rod 9, and the slider 4 is threadedly sleeved with the screw rod 9. Through this structural method, starting the driving motor 10 to drive the screw rod 9 to rotate can drive the slider 4 to rise and fall, wherein the slider 4 is set to a rectangular structure, and the slider 4 slides and fits with the side wall of the mounting arm 1 to prevent the slider 4 from rotating with the screw rod 9.

[0028] As a preferred implementation manner of this embodiment, the tensioning wheel group 3 includes a guide pulley 16 rotatably installed between the ends of a pair of tensioning arms 2, and a pair of guide pulleys 16 are arranged side by side. The enameled wire passes through between the two pairs of guide pulleys 16. While the enameled wire is tensioned, the enameled wire can be guided. A groove 17 is opened on the surface of the guide pulley 16, and the groove 17 is in an arc shape, which can prevent the enameled wire from detaching from the surface of the guide pulley 16.

[0029] In a further embodiment, the thrust arm 5 includes a first connecting arm 11, an insert rod 12 and a second connecting arm 13. One end of the first connecting arm 11 is rotationally connected to the slider 4, and the insert rod 12 is movably arranged at the end of the first connecting arm 11 away from the slider 4. The second connecting arm 13 is fixed to the end of the insert rod 12 extending out of the first connecting arm 11, and the second connecting arm 13 is rotationally connected to one end of the tensioning arm 2. A stopper 14 is fixed to the end of the insert rod 12 extending into the first connecting arm 11, and a spring 15 is arranged between the stopper 14 and the end wall of the first connecting arm 11 facing the slider 4. The spring 15 is used to elastically support the insert rod 12. When the tensioning arm 2 is forced to rotate to tension the enameled wire, a certain elastic buffer space is provided to avoid the enameled wire from breaking due to excessive tension. The second connecting arm 13 is rotationally connected to the connecting shaft 7, and the second connecting arm 13 is rotationally connected to the tensioning arm 2 through the connecting shaft 7, which can ensure that the first connecting arm 11, the second connecting arm 13 and the tensioning arm 2 are distributed in parallel.

[0030] Working principle: During the winding process, the enameled wire is passed through the two pairs of guide pulleys 16 in the two sets of tensioning wheel groups 3. By starting the drive motor 10 to drive the screw rod 9 to rotate, the slider 4 is driven to rise and fall, and the slider 4 drives the thrust arm 5 to rotate and move, forcing a pair of tensioning arms 2 to rotate a certain angle. Thus, the two pairs of guide pulleys 16 at both ends of a pair of tensioning arms 2 can tension the enameled wire to ensure that the coil wound by the enameled wire is of appropriate tightness and full tightness, thereby improving the quality of the coil. In addition, the tensioning method of rotating and tilting the tensioning arm 2 and the double-point tensioning method are adopted. Under the condition of limited contact distance of the enameled wire, a better tensioning effect can be obtained. At the same time, it is suitable for bidirectional transportation of the enameled wire and is more flexible. Furthermore, since the thrust arm 5 is composed of the first connecting arm 11, the insertion rod 12 and the second connecting arm 13, and the first connecting arm 11 is provided with a spring 15 for elastically supporting the insertion rod 12, when the tensioning arm 2 is forced to rotate to tension the enameled wire, there is a certain elastic buffer space, which can avoid the enameled wire from breaking due to excessive tension.
