[0018] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0019] Example 1 Please see Figures 1 to 13 The present invention preferably provides the following technical solution: a wire pushing and paper pushing device for a stator winding and embedding machine, comprising: a frame 101; a stator clamping mechanism, a turntable mechanism, and a stator wire pushing and paper pushing mechanism sequentially mounted on the frame 101 from top to bottom, wherein the turntable mechanism has four winding modules arranged in a ring, each winding module including a module body and a top core module disposed inside the module body; the stator wire pushing and paper pushing mechanism includes a first lead screw assembly, a second lead screw assembly disposed at the lifting end of the first lead screw assembly; an inner push rod assembly and an outer push rod assembly respectively disposed at the lifting ends of the first lead screw assembly and the second lead screw assembly and distributed inside and outside, and a buckle assembly disposed at the top of the inner push rod assembly for docking with the top core module; when the first lead screw assembly and the second lead screw assembly are running, the inner push rod assembly and the outer push rod assembly are pushed upward to simultaneously push the enameled wire 518 and the insulating paper into the stator.

[0020] It is known that the stator manufacturing process is roughly divided into four stages: core manufacturing, winding manufacturing, paper pushing / winding, and final processing. However, in the paper pushing and winding stages, traditional stator winding and winding machines often operate in multiple segments. This method easily leads to a decrease in the fit between the enameled wire 518 and the insulating paper. Therefore, this application designs a synchronous paper pushing and winding device for stator winding and winding machines, such as... Figure 1 As shown; Specifically, such as Figure 1 As shown, the stator's paper pushing and winding station is equipped with a stator clamping mechanism, a turntable mechanism, and a stator wire pushing and paper pushing mechanism, arranged sequentially from top to bottom. Preferably, four winding modules are mounted on the turntable mechanism. When the turntable mechanism rotates intermittently, a single winding module can sequentially perform paper loading, double-sided winding, and simultaneous paper and wire pushing into the stator. The paper loading and winding operations of the winding module can be performed by existing equipment, while the simultaneous paper and wire pushing into the stator is achieved by the stator clamping mechanism and the stator wire pushing and paper pushing mechanism. The stator can be placed on the stator clamping mechanism. When the winding module, after passing through the paper and wire loading stages, moves to below the stator, the stator clamping mechanism can lower the stator and connect it with the winding module. Figure 4As shown in the status, after the docking is completed, the stator wire pushing and paper pushing mechanism will then push the enameled wire 518 and the insulation wire on the winding module into the stator at the same time, completing the stator synchronous wire pushing and paper pushing process. Specific examples Figure 4 , 8 As shown in Figures 9 and 10, the stator wire pushing and paper pushing mechanism includes a first lead screw assembly, a second lead screw assembly connected to the lifting end of the first lead screw assembly, and inner push rod assemblies and outer push rod assemblies distributed internally and externally on the first lead screw assembly and the second lead screw assembly, respectively. The inner push rod assembly is connected to the top core module where the winding module is located via a snap-fit ​​assembly. Figure 4 , 6 As shown, when the turntable mechanism moves the winding module that has passed through the wire loading and paper loading to the bottom of the stator, the winding module can dock with the buckle assembly. After the stator clamping mechanism clamps the stator and the winding module, the stator wire pushing and paper pushing mechanism runs. The wire pushing and paper pushing process in this application is divided into four stages. Section 1: The first lead screw assembly can drive the inner push rod assembly and the outer push rod assembly to lift synchronously. The inner push rod assembly indirectly drives the top core module to lift and perform the wire pushing operation through the buckle assembly, while the outer push rod assembly is directly inserted into the winding module and placed under the insulating paper. Second stage: The first lead screw assembly and the second lead screw assembly are driven synchronously, and the second lead screw assembly moves faster than the first lead screw assembly. During this process, the inner push rod assembly pushes the enameled wire 518 upward, while the outer push rod assembly accelerates and pushes the insulating paper below the enameled wire 518. This stage is to align the top of the enameled wire 518 and the insulating paper and move them to the position where they are about to be inserted into the stator.

[0021] Three stages: The first lead screw assembly is accelerated upward to speed up the process of pushing the enameled wire 518 and the insulating paper into the stator; The fourth stage: The first lead screw assembly slowly rises, and the stator immediately completes the final stage of pushing the wire and paper. The slow insertion can ensure the quality of the embedding and reduce errors.

[0022] This application, through the stator clamping mechanism and stator wire and paper pushing mechanism, enables the synchronous advancement of the enameled wire 518 and insulating paper by the inner and outer push rod assemblies under the stator positioning state, using the ingenious drive of the first and second lead screw assemblies. Furthermore, under the structural characteristics of the first and second lead screw assemblies, not only is the enameled wire 518 and insulating paper pushed upward smoothly, but also the enameled wire 518 and insulating paper are positioned with high precision with the stator, improving the winding and paper embedding quality of the stator, and thus enhancing the fit between the stator insulating paper and the enameled wire 518.

[0023] Example 2 As another embodiment of the present invention, the turntable mechanism includes a turntable body 103 rotatably mounted in the middle of the frame 101; and a drive motor 104 mounted on the frame 101, wherein the output end of the drive motor 104 extends upward and is fixedly connected to the turntable body 103.

[0024] like Figure 3 As shown, the turntable body 103 is fixed on the output shaft of the drive motor 104. Under the intermittent drive of the drive motor 104, the winding module assembled on the turntable body 103 can sequentially realize the processing operations at each station.

[0025] Example 3 In another embodiment of this utility model, the mold body includes a mold base 511 and a winding post 512 arranged in a ring on the inner edge of the mold base 511, wherein a paper feeding groove 513 for the internal placement of insulating paper is formed between two adjacent winding posts 512; the top core module includes a telescopic post 514 disposed within a plurality of winding posts 512, wherein a liftable top post 515 is installed inside the telescopic post 514 and the diameter of the top end of the top post 515 decreases gradually from bottom to top, and its bottom end extends downward and is fixed with a locking block 516; and an I-shaped limiting sleeve 517 disposed at the bottom end of the telescopic post 514 and externally placed on the locking block 516, wherein the locking block 516, the I-shaped limiting sleeve 517 are connected to the buckle assembly.

[0026] like Figure 11 As shown, the mold body in the figure consists of a mold base 511, a ring-shaped distribution of winding posts 512, and a paper feeding groove 513 formed by adjacent winding posts 512. The telescopic post 514 containing the top core module is located between several winding posts 512, as shown in the figure. Figure 4 , 5 As shown in Figure 6, when the locking block 516 fixed at the bottom of the top column 515 mates with the buckle assembly and moves up and down, as... Figure 6 As shown in the diagram, the top post 515, under the action of the inner push rod assembly, can gradually lift the enameled wire 518, as... Figure 5 As shown, the external push rod assembly is gradually embedded inside several paper feeding slots 513 and pushes the insulating paper upward to realize the process of the enameled wire 518 and the insulating paper extending into the stator simultaneously.

[0027] Example 4 In another embodiment of this utility model, the first lead screw assembly includes two guide rods 111 fixed to the lower part of the frame 101, and a pusher plate 112 sleeved on the lower part of the two guide rods 111; first inner thread sleeves 113 fixed on both sides of the pusher plate 112, each first inner thread sleeve 113 having a first screw 114 inside, wherein the top ends of the two first screws 114 are respectively rotatably mounted to the middle part of the frame 101 through connecting pieces 115, and their bottom ends are connected to the bottom of the frame 101 and are provided with a first belt drive assembly. Under the action of the first belt drive assembly, the two first screws 114... The screws 114 rotate synchronously to achieve smooth lifting and lowering of the push plate 112; the first belt drive assembly includes a transmission sprocket 116 fixed at the bottom of each first screw 114, two positioning sprockets 117 rotatably mounted to the bottom of the frame 101; and a mounting base 118 set at the bottom of the frame 101. A first motor 119 is set on the mounting base 118, wherein the output end of the first motor 119 faces downward and is fixed with a drive sprocket 120, and a chain 121 that passes around the two positioning sprockets 117 is sleeved on the outer periphery of the drive sprocket 120 and the two transmission sprockets 116.

[0028] like Figure 3 As shown, two optical rods 111 are fixed to the lower part of the frame 101, and push-wire plates 112 are sleeved on the two optical rods 111, as... Figure 8 , 9 As shown in Figure 10, each of the first inner threaded sleeves 113 fixed on both sides has a first screw 114 inside, and the bottom ends of the two first screws 114 are respectively fixed with transmission sprockets 116. The drive sprocket 120 fixed at the telescopic end of the first motor 119 is fitted with a chain 121 around the outer periphery of the two transmission sprockets 116. At the same time, the chain 121 passes around two positioning sprockets 117 rotatably installed at the bottom of the frame 101, as shown in Figure 10. Figure 10 When the first motor 119 is driven, the two first screws 114 can be driven to rotate in place through the transmission action of the chain 121. Then, the two first inner screw sleeves 113 threadedly connected to the two first screws 114, the push plate 112 fixed to the two first inner screw sleeves 113, the second lead screw assembly and the inner push rod assembly assembled on the push plate 112 can be lifted and lowered simultaneously. The design of the chain 121 here can ensure the smoothness of the lifting and lowering of the push plate 112. Because the outer push rod assembly is mounted on the push plate 112 of the second lead screw assembly, the drive of the first lead screw assembly not only realizes the synchronous operation of the inner push rod assembly pushing the wire and the outer push rod assembly pushing the paper, but also the characteristic of the second lead screw assembly being faster than the first lead screw assembly allows the outer push rod assembly on it to be raised and lowered relative to the inner push rod assembly, so as to accelerate the lifting of the insulating paper relative to the enameled wire 518, thereby adjusting the tops of the insulating wire and the enameled wire 518 to be aligned, and improving the winding and paper embedding quality of the stator.

[0029] Example 5 In another embodiment of this utility model, the second lead screw assembly includes two first through holes opened on the pusher plate 112; a transmission sleeve 211 fixed on both sides of the pusher plate 112 and placed between the two first screws 114, with a second screw 212 rotatably installed inside each transmission sleeve 211, wherein the bottom end of each second screw 212 passes downward through the corresponding first through hole and is fixed with a second transmission gear 214, and the middle part is threadedly connected with a second inner thread sleeve 218; and a pusher plate 213 fixed between the two second inner thread sleeves 218 and assembled with the outer pusher assembly; a second motor 215 is also provided on the pusher plate 112, and a second drive gear 216 is fixed at the output end of the second motor 215, and a second transmission belt 217 is sleeved on the outer periphery of the second drive gear 216 and the two second transmission gears 214.

[0030] like Figure 8 , 9 As shown in Figure 10, both second screws 212 are rotatably mounted on the push plate 112 via transmission sleeves 211. A push plate 213 is fixed between the two second inner screw sleeves 218 connected to the outer circumference of the two second screws 212. At the same time, the second transmission gears 214 fixed to the bottom ends of the two second screws 212 and the second drive gears 216 fixed to the output end of the second motor 215 are fitted with second transmission belts 217. Therefore, when the second motor 215 drives, the two second screws 212 can be synchronously rotated through the transmission action of the second transmission belts 217, thereby achieving the smooth lifting and lowering of the two second inner screw sleeves 218, the push plate 213, and the outer push rod assembly.

[0031] Example 6 In another embodiment of this utility model, the external push rod assembly includes an assembly seat 219 mounted in the middle of the push plate 213. A push rod 222 is fixed in a ring on the assembly seat 219. A plurality of push rods 222 extend upward and are aligned with a plurality of paper feeding slots 513. When the first lead screw assembly and the second lead screw assembly move up and down, the plurality of push rods 222 can push the insulating paper inside the plurality of paper feeding slots 513 into the slot of the stator.

[0032] The stator slots are a mature, existing technology; they are stator slots used to hold insulating paper, such as... Figure 4 The mounting base 219 is fixedly assembled with the push plate 213, and the push rod 222 is fixedly fixed on the mounting base 219 in a ring.

[0034] like Figure 4 , 6 As shown, one end of the top shaft 220 is assembled with the pusher plate 112, and the other end is connected to the top core module through a snap-fit ​​assembly.

Simultaneously, the guide head 425, mounted on the output end of the Airtac rod non-returning cylinder 424, is aligned with the center of the circular hole and with the inner hole of the stator. When stator positioning is required, specifically... Figure 2 As shown; First, the hydraulic cylinder 413 operates, then the assembly frame 417 moves down and places the stator on top of several winding posts 512 and mates with them. This process can achieve the limiting of the bottom of the stator. After the bottom of the stator is connected, the Airtac rod non-returning cylinder 424 drives the guide head 425 to move down and connect with the inner ring of the stator for positioning. This process achieves the limiting of the middle part of the stator. After the middle of the stator is stopped, the fourth motor 421 drives the two fourth screws 414 to rotate, and the pressure plate 416 moves down and presses down on the top of the stator. In this embodiment, the stator bottom, middle and top are positioned sequentially by the front and rear drive cooperation of hydraulic cylinder 413, Airtac rod non-returning cylinder 424 and fourth motor 421, thereby achieving high-precision and high-stability positioning of the stator.
