[0002] In the current stator winding machines, since the stator is annular in design, the winding grooves in the stator are evenly distributed along the circumference, and there are gaps between adjacent winding grooves. After completing the winding work of one winding groove, the needle bar of the winding machine needs to enter the next winding groove. In the existing stator winding machines, the needle bar assembly can only pass the wire from under the stator. In some stator structures, this wire passing method is not applicable and causes interference. Utility Model Content

[0026] Reference throughout the specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, when the phrases "in one embodiment" or "in some embodiments" appear in various places throughout the specification, not all references are to the same embodiment. Furthermore, in one or more embodiments, the particular features, structures, or characteristics may be combined in any suitable manner.

[0027] Reference Figure 1 , Figure 2 The winding device provided in the embodiment of the present application includes a vertically arranged first cylinder 10 and a rotatable needle rod assembly 20 driven by the first cylinder 10, and also includes a second cylinder 30 arranged on the frame and a connecting rod assembly 40 connected to the piston rod 31 of the second cylinder 30. The first cylinder 10 is connected to the connecting rod assembly 40 and can be driven by the connecting rod assembly to switch the first cylinder 10 and the needle rod assembly 20 between a horizontal position and a vertical position.

[0028] In the present embodiment, a second cylinder 30 and a connecting rod assembly 40 are added to the winding device. Driven by the second cylinder 30 and the connecting rod assembly 40, the first cylinder 10 and the needle rod assembly 20 can be switched between a horizontal position and a vertical position. When winding, the first cylinder 10 and the needle rod assembly 20 are vertically arranged. When several winding posts of the same phase complete winding, the first cylinder 10 and the needle rod assembly 20 flip to a horizontal position for passing the wire, and then flip to a vertical position when winding. At the same time, since the needle rod assembly 20 can be driven by the first cylinder 10 to rotate, it can also pass the wire in a vertical position, that is, the needle rod assembly 20 is rotated a certain angle to avoid the winding post for passing the wire. In this way, the winding device in the present embodiment has two wire passing structures, which can pass the wire horizontally or vertically. When this winding device is applied to different winding machines, a suitable wire passing method can be selected according to needs, which brings more convenience to users and better versatility.

[0029] Specifically, the second cylinder 30 is fixed on a support frame 50, and the connecting rod assembly 40 includes a connecting rod 41 and a column 42 respectively located on both sides of the support frame 50, and a rotating shaft (not shown in the figure) passing through the support frame 50, one end of the rotating shaft is fixedly connected to one end of the connecting rod 41, and the other end of the rotating shaft is fixedly connected to one end of the column 42, the other end of the connecting rod 41 is connected to the piston rod 31 of the second cylinder 30, and the other end of the column 42 is fixedly connected to the first cylinder 10. When the piston rod 31 of the second cylinder 30 is extended or retracted, the piston rod 31 drives the connecting rod 41 to rotate forward or reverse around the rotating shaft, and when the rotating shaft rotates accordingly, it drives the column 42 at the other end and the first cylinder 10 to rotate 90 degrees, that is, switch between the vertical position and the horizontal position.

[0030] Further, the two ends of the rotating shaft are respectively fixedly connected to one end of the connecting rod 41 and one end of the column 42 through the bearing 43. In this way, the components at the two ends of the rotating shaft can be better connected to the rotating shaft for rotation.

[0031] Furthermore, a reinforcement 60 is provided at the other end of the column 42, the first cylinder 10 is provided on the upper part of the reinforcement 60, and the needle bar assembly 20 is provided on the lower part of the reinforcement 60. In this embodiment, the reinforcement 60 is provided between the column 42 and the first cylinder 10, and the reinforcement 60 is also located between the needle bar assembly 20 and the first cylinder 10. The reinforcement 60 enhances the connection strength between the needle bar assembly 20 and the cylinder, meets the tension requirement during winding, has high reliability and durability, and is applied to the winding machine to ensure that the whole machine still has stable performance after long-term use.

[0032] Reference Figure 2 In this embodiment, a guide member 70 is provided at the bottom of the reinforcement member 60. The guide member 70 is straight and long, and is vertically arranged. The guide member 70 has a guide hole 71 that runs through from top to bottom. The needle bar assembly 20 includes a needle bar 21, a thread nozzle seat 22 arranged at the bottom of the needle bar 21, and a thread nozzle 23 extending from the thread nozzle seat 22. During installation, the needle bar 21 is connected to the piston rod of the first cylinder 10 and is inserted into the guide hole 71, while the thread nozzle seat 22 is hinged to the bottom of the guide member 70, and the thread nozzle 23 extends out of the guide member 70. In this way, when the needle bar 21 moves up and down along the guide hole 71 driven by the piston rod, the thread nozzle seat 22 is driven to rotate around the hinge shaft on the guide member 70, thereby causing the thread nozzle 23 to rotate accordingly, changing the position of the thread nozzle 23 so that it can avoid the winding groove for convenient thread passing.

[0033] In this embodiment, the piston rod of the first cylinder 10 is fixedly connected to the needle rod 21 through an adapter 80. The first cylinder 10 is not arranged directly above the needle rod 21, so the connection with the needle rod 21 is achieved through the adapter 80. Of course, in other embodiments, the first cylinder 10 can be arranged directly above the needle rod 21, and the needle rod 21 can be directly connected to the piston rod.

[0034] Depend on Figure 2As shown, the adapter 80 is horizontally arranged on the reinforcement member 60, one end of the adapter 80 is connected to the piston rod of the first cylinder 10, and the other end of the adapter 80 is fixedly connected to the top end of the needle rod 21. Specifically, the other end of the adapter 80 is provided with a mounting hole 81 connected to the guide hole 71, and the top end of the needle rod 21 extends into the mounting hole 81 and is fixed in the mounting hole 81 through an insertion shaft. In this way, when the piston rod of the first cylinder 10 drives the adapter 80 to move, the adapter 80 drives the needle rod 21 to move accordingly.

[0035] In this embodiment, a plurality of weight-reducing holes 90 are provided on the reinforcement member 60 and the column 42. By providing the weight-reducing holes 90, the weight of the reinforcement member 60 and the column 42 is reduced while satisfying the reinforcement and connection functions, thereby avoiding adding excessive load pressure to the winding device.

[0036] The present application also discloses a stator winding machine wire (not shown in the figure), including a frame, a fixing device provided on the frame for fixing the stator, and a winding device provided on the frame for winding the stator, and the winding device is the aforementioned winding device. Due to the provision of the aforementioned winding device with two wire passing structures, the winding of the winding machine is more convenient, more selective, and convenient for users to use.

[0037] The above description is only an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
