[0002] The motor stator is the stationary part of the motor. The main function of the stator is to generate a rotating magnetic field. The stator includes a stator core and a stator coil winding. The stator core is provided with a squirrel cage hole. During assembly, the stator coil winding is assembled in the squirrel cage hole. The winding workload of the stator coil is large, and the enameled wire used is generally thin, so high-speed winding machines are mostly used when winding the stator coil. During the production process of the motor stator coil, a winding machine is usually required to wind the copper wire on the winding mold. However, the inner diameter of the connecting cylinder of the existing motor stator coil winding machine is fixed, so that the device can only fix the connecting shaft connected to one end of the winding mold and the winding mold whose inner diameter size matches the connecting cylinder, which limits the scope of application of the device to the winding mold.

[0003] After searching, the Chinese patent publication number CN217956919U discloses a motor stator coil winding machine, including a workbench, a drive box shell is fixedly installed on one side of the upper end surface of the workbench, a drive motor is fixedly installed on one side wall of the drive box shell, a rotating shaft is rotatably installed on one side wall of the drive box shell through a rotating shaft, the output end of the drive motor is connected to the rotating shaft of the rotating shaft, a connecting cylinder is fixedly installed on one end of the rotating shaft away from the drive box shell, clamping plates are provided on the upper and lower end surfaces of the connecting cylinder, and connecting holes are opened on the upper and lower side walls of the connecting cylinder.

[0004] However, it is found in actual use that when connecting the winding mold, two fixing bolts need to be tightened and fixed separately, which may increase the connection and adjustment time and affect the winding efficiency. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that when connecting the winding mold, two fixing bolts need to be tightened and fixed separately, which may increase the connection and adjustment time and affect the winding efficiency, and to propose a motor coil winding machine.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A motor coil winding machine includes a workbench and also includes: a connecting cylinder fixedly connected to the workbench, wherein a movable rod is slidably connected in the cavity of the connecting cylinder, a limiting plate is fixedly connected to the movable rod, an air bag is arranged on the contact surface of the limiting plate, when the limiting plate moves toward the connecting shaft on the winding mold, the air bag fits with the outside of the connecting shaft; a limiting assembly is used to fix the position of the connecting cylinder.

[0008] In order to facilitate stable fixation of the position of the connecting tube, preferably, the limiting assembly includes a limiting rod, a mounting plate is fixedly connected to the workbench, and two ends of the limiting rod are respectively fixedly connected to the connecting tube and the mounting plate.

[0009] In order to facilitate the installation of the position of the limiting rod, further, a limiting groove is provided on the mounting plate, and the limiting rod is fixedly connected to the inner wall of the limiting groove.

[0010] In order to facilitate the inflation of the airbag, preferably, a booster cylinder is fixedly connected to the outer wall of the connecting cylinder, one end of the movable rod extends into the booster cylinder and is fixedly connected to a piston, and the piston fits against the inner wall of the booster cylinder, and the cavity below the piston is connected to the airbag through a pipe.

[0013] Compared with the prior art, the utility model provides a motor coil winding machine, which has the following beneficial effects:

[0014] 1. The motor coil winding machine drives the limit plate to move toward the outside of the connecting shaft on the winding mold through the movable rod. At this time, the convex block on the limit plate will fit with the outside of the connecting shaft on the winding mold, and then the outside of the connecting shaft on the winding mold can be limited and offset, so that the connecting shaft on the winding mold can be quickly limited and fixed, and the time for connection and adjustment can be reduced, thereby improving the efficiency of subsequent winding;

[0015] 2. The motor coil winding machine, when the movable rod descends, the airbag will be filled with gas, thereby enhancing the friction between the bump and the outside of the connecting shaft on the winding mold, making the contact between the airbag and the outer wall of the connecting shaft on the winding mold closer, so that the airbag and the outside of the connecting shaft fit together, while improving the stability of the connecting shaft, the connecting shaft can also be quickly connected and installed.

[0016] The parts not involved in the device are the same as the prior art or can be implemented by using the prior art. On the one hand, the utility model can limit and offset the outside of the connecting shaft on the winding mold, so that it can quickly limit and fix the connecting shaft on the winding mold, while also reducing the time for connection and adjustment, and improving the efficiency of subsequent winding. On the other hand, the airbag can be used to enhance the friction between the protrusion and the outside of the connecting shaft on the winding mold, so that the contact between the airbag and the outer wall of the connecting shaft on the winding mold is closer, thereby making the airbag fit the outside of the connecting shaft, while improving the stability of the connecting shaft, the connecting shaft can also be quickly connected and installed.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] Example:

[0025] Reference Figure 1-Figure 4 A motor coil winding machine includes a workbench 1, a mounting plate 101 is fixedly connected to the workbench 1, a limiting groove 6 is provided on the mounting plate 101, a limiting rod 601 is fixedly connected to the inner wall of the limiting groove 6, and three groups of limiting rods 601 are evenly distributed in a circle, and a connecting tube 2 is fixedly installed at the connecting end of the limiting rod 601 to limit and fix the position of the connecting tube 2.

[0026] A cavity is also provided on the connecting tube 2, and the cavity can be used to connect the connecting shaft on the winding mold. The style of the winding mold can be the winding mold in the patent with patent publication number: CN209329923U.

[0027] There are multiple groups of movable rods 501 equidistantly distributed in a circle in the cavity of the connecting tube 2. Figure 1 As shown in the figure, there can be 6 groups or 8 groups to improve the limiting effect of the connecting cylinder 2, and the movable rod 501 is fixedly connected to the limiting plate 3, and the contact surface of the limiting plate 3 is provided with an airbag 4, and the outer wall of the connecting cylinder 2 is fixedly connected with booster cylinders 5 whose number is the same as that of the movable rod 501 and whose position corresponds to that of the movable rod 501, and one end of the movable rod 501 extends into the booster cylinder 5 and is fixedly connected with a piston 502, and the piston 502 fits against the inner wall of the booster cylinder 5, and the cavity below the piston 502 is connected with the airbag 4 through a pipe.

[0028] A spring 503 is fixedly connected to the top of the piston 502, and the connecting end of the spring 503 is fixedly connected to the inner wall of the booster cylinder 5. The cavity above the piston 502 is connected to the output end of the air pump through a pipeline, and an electromagnetic control valve can be set on the pipeline to control the passage of the pipeline.

[0029] When it is necessary to limit the connection of the connecting shaft of the winding mold, the connecting shaft on the winding mold can be inserted into the cavity of the connecting tube 2, and then the switch of the air pump is started. At this time, the gas delivered by the air pump will enter the boosting tube 5, and the gas is above the piston 502. As the air pressure increases, the piston 502 drives the movable rod 501 to descend.

[0030] At this time, multiple groups of movable rods 501 that are evenly distributed and equidistant around the circumference will drive the limit plate 3 to move toward the outside of the connecting shaft on the winding mold. A protrusion 301 is also fixedly connected to the limit plate 3, and the airbag 4 is arranged on one side of the protrusion 301, so that the airbag 4 can be used in conjunction with the protrusion 301. The cross-section of the protrusion 301 is trapezoidal. At this time, the protrusion 301 will fit with the outside of the connecting shaft on the winding mold, and then the outside of the connecting shaft on the winding mold can be limited and offset, so that the connecting shaft on the winding mold can be quickly limited and fixed, while also reducing the time for connection and adjustment, and improving the efficiency of subsequent winding.

[0031] It should be explained that when the movable rod 501 descends, the gas in the cavity below the piston 502 will be compressed, and the compressed air will be transported to the airbag 4. At this time, the airbag 4 will be filled with gas and can cooperate with the limit plate 3 to enhance the friction between the protrusion 301 and the outside of the connecting shaft on the winding mold, so that the contact between the airbag 4 and the outer wall of the connecting shaft on the winding mold is closer, and then the airbag 4 is fit with the outside of the connecting shaft, while improving the stability of the connecting shaft, the connecting shaft can also be quickly connected and installed.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
