[0037] Reference Figure 1-Figure 3 A double-station skew slot winding machine provided in an embodiment of the present application includes a frame 10, a stator mounting mechanism disposed on the frame 10 for fixing a skew slot stator 20, and a winding mechanism disposed beside the stator mounting mechanism for winding the skew slot stator 20, the winding mechanism includes a displacement mechanism 30 and two winding devices 40 disposed on the displacement mechanism 30, the stator mounting mechanism includes a clamp assembly 50 for fixing the skew slot stator 20, and a driving motor 60 for driving the clamp assembly 50 and the skew slot stator 20 to rotate, the winding device 40 includes a pay-off wheel 41 for releasing copper wire and a wire nozzle 42 for copper wire to pass through for winding, the wire nozzle 42 is inclined relative to a vertical plane, and the inclination angle between the wire nozzle 42 and the vertical plane is the same as the inclination angle between the skew slot 21 on the skew slot stator 20 and the vertical plane, during winding, the wire nozzle 42 moves up and down driven by the displacement mechanism 30, and at the same time, the driving motor 60 drives the skew slot stator 20 to rotate to wind the winding posts in different skew slots 21.

[0038] In this embodiment, the wire nozzle 42 of the winding device 40 is tilted and coordinated with the rotation of the skew slot stator 20, so that the winding of the skew slot stator 20 is quickly completed. This structure is simple, low in cost, and high in winding efficiency.

[0039] Specifically, refer to Figure 4 The wire nozzle 42 includes a cylindrical mounting portion 421 and a wire outlet portion 422 extending from the mounting portion 421. A wire outlet hole 423 is provided between the wire outlet portion 422 and the mounting portion 421. The wire outlet portion 422 is arranged obliquely, and the width of the wire outlet portion 422 is smaller than the width of the inclined groove. When winding, the copper wire is released from the pay-off wheel 41, passes through the wire outlet hole 423, and extends from the wire outlet portion 422. A mounting plane 424 is provided on the surface of the cylindrical mounting portion 421, and the self-rotation of the wire nozzle 42 is prevented after installation by using the mounting plane 424.

[0040] In this embodiment, the outlet portion 422 is flat, and the flat outlet portion 422 is suitable for thicker copper wires. When the copper group is thin, a cylindrical outlet portion 422 is used. That is, the shape of the outlet portion 422 can be selected according to the wire diameter of the copper group, but no matter what shape the outlet portion is, it is installed in an inclined manner to cooperate with the rotation of the skewed slot stator 20 for winding.

[0041] Reference Figure 2 The displacement mechanism 30 of the winding device 40 includes a lifting mechanism 31 that drives the winding device 40 to move up and down during winding, a left-right moving mechanism 32 that drives the lifting mechanism 31 to move horizontally, and a front-back moving mechanism 33 that drives the lifting mechanism 31 and the left-right moving mechanism 32 to move forward and backward. The lifting mechanism 31 and the left-right moving mechanism 32 cooperate to wind in a circle at the same time, and the front-back moving mechanism 33 drives the winding device 40 to move forward and backward when the wire is fed or the winding is completed. Among them, the lifting mechanism 31 is moved by belt drive to make the up and down movement more stable, while the left-right moving mechanism 32 and the front-back moving mechanism 33 are mainly moved in a straight line by means of cylinders, slide rails, and sliders, which will not be repeated here.

[0042] Reference Figure 5 , Figure 6 and Figure 7 The clamp assembly 50 includes a support column 51 connected to the output shaft of the driving motor 60 and used to support the skew slot stator 20, and two claw clamps 52 arranged in the support column 51 and relatively openable / closable for clamping / relaxing the skew slot stator 20. In this embodiment, the skew slot stator 20 is installed by using the support column 51 and the claw clamp 52 in cooperation, which has a simple structure and is easy to install and disassemble.

[0043] Furthermore, the opening and closing of the two claw clamps 52 are achieved by two pushing components 70, an elastic member 80 and a guide mechanism 90. The pushing component 70 is arranged on the outside of the clamp component 50, the guide mechanism 90 is arranged between the support column 51 and the claw clamp 52, and the elastic member 80 is arranged between the two claw clamps 52. The above components are used to cooperate with the pushing action to assist the claw clamp 52 to open or close.

[0044] Depend on Figure 6 , Figure 7 As can be seen in the figure, a first mounting hole 511 is longitudinally provided in the support column 51, and a through hole 512 communicating with the first mounting hole 511 is horizontally provided at the bottom of the support column 51. The claw clamp 52 is in an inverted L-shape, and the vertical portion 521 of the claw clamp 52 extends into the first mounting hole 511, while the horizontal portion 522 is located at the top of the support column 51 to press / release the top surface of the skewed slot stator 20. The two push-up assemblies 70 include two push rods 71 ​​located on both sides of the through hole 512 and can extend into the through hole 512 for pushing up the two claw clamps 52, and a translation mechanism 72 provided on the frame 10 and capable of driving the two push rods 71 ​​to move horizontally. The guide mechanism 90 includes a slide bar assembly provided on the vertical portion 521 and a slide slot assembly obliquely provided on the support column 51, and the slide bar assembly extends into the slide slot assembly. Specifically, in this embodiment, the slide slot assembly has two slide slots 91, which are relatively provided on the support column 51 and cross-intersect with the through hole 512. Each slide slot has two inclined slots 911, and the two inclined slots 911 are arranged in an eight-shaped shape. The slide bar assembly includes two groups of slide bars 92, which are also arranged opposite to each other, and the positions correspond to the two slide slots. Each group of slide bars has two slide bars 92, and the two slide bars 92 extend into the two inclined slots 911 of each slide slot 91 respectively. When the push rod 71 pushes the claw clamp 52, the claw clamp 52 moves, and the slide bar 92 on the claw clamp 52 moves upward along the inclined slot 911, driving the claw clamp 52 to move upward. At this time, the horizontal part 522 of the claw clamp 52 releases the top surface of the inclined slot stator 20 upward. When the thrust of the push rod 71 is canceled, the two claw clamps 52 move under the push of the elastic member 80, and the slide bar 92 moves downward along the inclined slot 911 to return to its original position.

[0045] Furthermore, the elastic member 80 is a spring. The vertical portions 521 of the two claw clamps 52 are oppositely provided with two second mounting holes 523, and the two ends of the spring are respectively placed in the two second mounting holes 523. When the skew slot stator 20 is installed, the spring is in a telescopic state, and the two claw clamps 52 are squeezed apart to be firmly pressed against the top surface of the skew slot stator 20. When the two claw clamps 52 are pushed up by the two push rods 71, the two claw clamps 52 are squeezed together to make the spring in a compressed state.

[0046] In this embodiment, there are three elastic members 80, which are arranged at intervals on the vertical portion 521 of the claw clamp 52. The above-mentioned slide groove components are arranged at intervals up and down along the support column 51. In this way, when the claw clamp 52 moves, there are force points of the slide groove 91 and the slide rod 92 at both the upper and lower parts, and the two groups of elastic members 80 have a more balanced pushing effect on the claw clamp 52.

[0047] Reference Figure 3 and Figure 5 The translation mechanism 72 includes two cylinders 721 arranged opposite to each other in the horizontal direction, two moving rods 722 driven by the two cylinders 721, and two fixed blocks 723 respectively arranged on the two moving rods 722. The two push rods 71 ​​are respectively arranged on the two fixed blocks 723. The two cylinders 721 drive the two push rods 71 ​​to move in the opposite direction, so as to push the claw clamp 52 from both ends of the through hole 512 and release the claw clamp 52. In this embodiment, there is a double-station winding device 40, that is, winding is performed on two skewed slot stators 20 at the same time. The two skewed slot stators 20 are clamped at the same time. Therefore, the two push rods 71 ​​on the left side of the clamp assembly 50 of the two skewed slot stators 20 are driven by the cylinder 721 on the left side at the same time, and the two push rods 71 ​​on the right side are driven by the cylinder 721 on the right side at the same time. The two push rods 71 ​​on the left side are fixed on the same moving rod 722, and the two push rods 71 ​​on the right side are fixed on another moving rod 722. The use of this simultaneous driving structure makes the entire structure simple, low in cost, and high in efficiency.

[0048] The above description is only a specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
