This device is usually made of insulating materials, which can effectively isolate each phase winding, prevent current leakage and short - circuits between them, thus ensuring the safe operation of the generator.

[0003] Nowadays, most common phase - to - phase insulation devices for the windings at the end of the terminal are formed by winding metal wires into a willow shape outside, then placing insulating paper inside the stator, and manually placing the metal wires into the insulating paper of the motor stator so that the insulating paper wraps the wound metal wires. However, most traditional winding devices cannot directly wind at the end of the motor stator. And the metal wires wrapped with insulating paper are easily affected by the fragility of the insulating paper, and are prone to breakage and leakage problems when installed at the end of the motor stator.

[0049] The working principle and beneficial effects of the present invention are as follows:

[0050] 1. In the present invention, when winding a metal wire inside the stator body, the U-shaped insulator is placed in the corresponding insulating groove. By pulling the positioning slide rod, under the rebound of the positioning spring, the anti-slip positioning block clamps the stator body. Under the uniform force of multiple positioning springs, the position of the positioning slide rod is fixed by tightening the positioning bolt, so that the position of the stator body can be fixed, and the power reciprocating lead screw is located in the middle of the stator body. Compared with the prior art, by setting the U-shaped insulator to replace the insulating paper, it is not only firmly set, but also not easily damaged;

[0051] 2. In the present invention, when winding a metal wire, one end of the metal wire to be wound is sequentially fixed on a U-shaped insulator corresponding to the insulating groove by passing through a wire-drawing cavity, a first wire-passing ring, and a second wire-passing ring. When threading the wire in the U-shaped insulator, the power motor is started. The power motor drives the power reciprocating lead screw to rotate. By the rotation of the power reciprocating lead screw, the power ball nut group performs a linear reciprocating motion. The motion of the power ball nut group drives the winding plate to move. The movement of the winding plate drives the wire holder to move. The movement of the wire holder drives the wire electric cylinder, the wire rod, and the second wire-passing ring to move. The metal wire is driven to penetrate and move in the U-shaped insulator through the second wire-passing ring, and the wire is placed in the U-shaped insulator;

[0052] 3. In the present invention, when winding the metal wire into the remaining U-shaped insulators, the movement of the winding plate will also drive the pneumatic limiting slide rod to move. The movement of the pneumatic limiting slide rod will drive the positioning slider to move. When the movement of the positioning slider squeezes the air supply area, the inflation valve and the suction and discharge valve are opened, and the suction and discharge valve is closed. The gas in the air supply area will be squeezed into the annular folding box through the inflation pipe. When the air pressure in the annular folding box increases, under the action of the pressure, the folding slide rod will move towards one side of the U-shaped insulator, so that the folding slide rod moves between two adjacent U-shaped insulators. Then the positioning motor is started. The output end of the positioning motor will drive the positioning gear to rotate. The rotation of the positioning gear drives the annular internal gear to rotate. The rotation of the annular internal gear drives the positioning disc to rotate. The rotation of the positioning disc drives the positioning component to rotate. By the rotation of the positioning component, the stator body and the U-shaped insulator are driven to move. Under the movement of the U-shaped insulator, the metal wire will be driven to move. And under the block of the folding slide rod, the metal wire will be bent on one side of the U-shaped insulator. After the next U-shaped insulator moves to one side of the wire groove, the inflation valve is closed, the supply and discharge valve is opened, and the power motor is started again. The metal wire is driven by the second wire-passing ring to wind the U-shaped insulator. This process is repeated. With the cooperation of the positioning component and the pneumatic winding component, the winding of the metal wire in the U-shaped insulator can be realized. Conversely, through the movement of the positioning slider, the gas in the annular folding box can also be pumped into the pneumatic positioning cylinder, so that the folding slide rod shrinks into the annular folding box;

[0053] 4. In the present invention, during the process of winding the metal wire, through the contact between the annular folding box and the U-shaped insulator, it can effectively prevent the metal wire from overflowing from the U-shaped insulator. When the metal wire wound in the U-shaped insulator gradually increases, the wire electric cylinder can be started. The output end of the wire electric cylinder drives the wire rod and the second wire-passing ring to move, so as to adjust the position of the second wire-passing ring;

[0054] 5. In the present invention, when threading the wire, by starting the wire pulling motor, the output end of the wire pulling motor drives the connected wire pulling roller to rotate. Under the meshing of the wire pulling gears, the wire pulling roller drives the metal wire to move, conveying the metal wire, and realizing the willow winding of the metal wire. After the metal wire winding is completed, an insulating material is also wound around the part of the metal wire exposed on one side of the electronic stator to complete the wire winding operation.

[0066] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0067] As Figures 1 to 8 shown, this embodiment proposes a device for winding the interphase insulation of the end winding of a generator stator, which includes a stator body 1, and also includes a U-shaped insulator 2, a pneumatic positioning cylinder 3, a positioning assembly 002, an annular broken line box 6, and a pneumatic winding assembly 003.

[0068] For the above, there are multiple U-shaped insulators 2, and multiple insulation grooves adapted to the U-shaped insulators 2 are equally angled on the stator body 1. The U-shaped insulators 2 are penetrated and arranged in the insulation grooves. A positioning slider 4 is hermetically and slidably arranged in the pneumatic positioning cylinder 3.

[0069] Among them, the adjustment assembly 001 includes a positioning adjustment disk 8, an annular internal gear 9, a positioning adjustment motor 10, and a positioning adjustment gear 11. The positioning adjustment disk 8 is rotatably arranged on the power disk 5. The positioning assembly 002 is arranged on the positioning adjustment disk 8. The annular internal gear 9 is arranged on the side of the positioning adjustment disk 8 away from the positioning assembly 002. The positioning adjustment motor 10 is installed on the power disk 5. The positioning adjustment gear 11 is arranged on the output end of the positioning adjustment motor 10. The positioning adjustment gear 11 meshes with the annular internal gear 9.

[0070] Specifically, when the positioning motor 10 is started, the output end of the positioning motor 10 drives the positioning gear 11 to rotate. The rotation of the positioning gear 11 drives the annular internal gear 9 to rotate. The rotation of the annular internal gear 9 drives the positioning disk 8 to rotate. The rotation of the positioning disk 8 drives the positioning component 002 to rotate. Through the rotation of the positioning component 002, the stator body 1 and the U-shaped insulator 2 are driven to move.

[0071] As described above, multiple groups of the positioning components 002 are provided. The multiple groups of positioning components 002 are arranged at equal angles on the positioning component 001 and are used to position the stator body 1. The positioning component 002 includes a positioning plate 12, a positioning slide bar 13, a positioning spring 15, and an anti-slip positioning block 16. The positioning plate 12 is arranged on the positioning disk 8. The positioning slide bar 13 penetrates and is slidably arranged on the positioning plate 12. A positioning bolt 14 for fixing the positioning slide bar 13 is threadedly connected to the positioning plate 12. The positioning spring 15 is arranged between one end of the positioning slide bar 13 and the positioning plate 12. The anti-slip positioning block 16 is arranged on the positioning slide bar 13 and is used to clamp the stator body 1.

[0072] Specifically, when winding metal wires inside the stator body 1, the U-shaped insulator 2 is placed in the corresponding insulating groove. By pulling the positioning slide bar 13, under the resilience of the positioning spring 15, the anti-slip positioning block 16 clamps the stator body 1. When multiple positioning springs 15 are uniformly stressed, by tightening the positioning bolt 14, the position of the positioning slide bar 13 is fixed, and thus the position of the stator body 1 can be fixed, making the power reciprocating lead screw 18 located at the middle position of the stator body 1.

[0073] As described above, the annular folded line box 6 is arranged on the pneumatic positioning cylinder 3 through the support plate 7. A wire winding groove is formed on one side of the annular folded line box 6. The annular folded line box 6 is connected to the U-shaped insulator 2.

[0074] As described above, the pneumatic wire winding component 003 is connected in communication between the annular folded line box 6 and the pneumatic positioning cylinder 3 and is used to drive the metal wire to wind around the U-shaped insulator 2. And the pneumatic wire winding component 003 is connected to the positioning slider 4 and is used to drive the positioning slider 4 to move. The pneumatic wire winding component 003 includes a wire winding power part, a pneumatic folded line part, and a wire guiding part. The wire winding power part is arranged between the annular folded line box 6 and the power disk 5. The wire winding power part is connected to the positioning slider 4. The pneumatic folded line part is connected in communication between the annular folded line box 6 and the pneumatic positioning cylinder 3 and is used to bend the wound metal wire. The wire guiding part is arranged on the wire winding power part and is used to guide the metal wire. The wire guiding part corresponds to the wire winding groove.

[0075] Among them, the winding power unit includes a power frame 17, a power reciprocating lead screw 18, a power motor 20, a winding plate 21, and a pneumatic limit slide bar 22. The power frame 17 is arranged on the annular folding box 6. The power reciprocating lead screw 18 is rotatably arranged between the power frame 17 and the power disk 5. A power ball nut group 19 is threadedly connected to the power reciprocating lead screw 18. The power motor 20 is installed on the power frame 17, and the output end of the power motor 20 is connected to one end of the power reciprocating lead screw 18. The winding plate 21 is arranged on the power ball nut group 19. There are multiple pneumatic limit slide bars 22, which are hermetically and slidably arranged on the pneumatic positioning cylinder 3. One end of the pneumatic limit slide bar 22 is connected to the winding plate 21, and the other end of the pneumatic limit slide bar 22 is connected to the positioning slider 4.

[0076] Among them, the pneumatic folding part includes a folding group and a charging and discharging group. There are two groups of folding groups, which are symmetrically hermetically and slidably arranged on the annular folding box 6. The U-shaped insulator 2 is located between the two groups of folding groups and is used to bend the metal wire wound inside the U-shaped insulator 2. The charging and discharging group is connected between the pneumatic positioning cylinder 3 and the annular folding box 6 and is used to adjust the air pressure inside the annular folding box 6.

[0077] The folding group includes folding slide bars 23. There are multiple folding slide bars 23, which correspond to the U-shaped insulator 2 one by one. The folding slide bars 23 penetrate and are hermetically slidably arranged on one side of the annular folding box 6.

[0078] The charging and discharging group includes a charging pipe 24, a supply and discharge pipe 26, and a suction and discharge pipe 28. There are multiple charging pipes 24, which are connected between the annular folding box 6 and the air supply area. An inflation valve 25 is installed on the charging pipe 24. There are multiple supply and discharge pipes 26, which are connected to the air supply area. A supply and discharge valve 27 is installed on the supply and discharge pipe 26. There are multiple suction and discharge pipes 28, which are connected to the suction area. A suction and discharge valve 29 is installed on the suction and discharge pipe 28.

[0079] The wire part includes a wire frame 30, a wire electric cylinder 32, and a wire rod 33. The wire frame 30 is arranged on the winding plate 21. A wire threading ring one 31 is arranged on one side of the wire frame 30. The wire electric cylinder 32 is arranged on the wire frame 30. One end of the wire rod 33 is arranged on the output end of the wire electric cylinder 32, and the other end of the wire rod 33 penetrates the winding groove and the U-shaped insulator 2 and is provided with a wire threading ring two 34.

[0080] Specifically, when winding a metal wire, one end of the metal wire to be wound is sequentially fixed on the U-shaped insulator 2 corresponding to the insulating groove by passing through the wire-drawing cavity, the first wire-passing ring 31, and the second wire-passing ring 34. When threading the wire in the U-shaped insulator 2, the power motor 20 is started. The power motor 20 drives the power reciprocating lead screw 18 to rotate. By the rotation of the power reciprocating lead screw 18, the power ball nut group 19 performs a linear reciprocating motion. The motion of the power ball nut group 19 drives the wire-winding plate 21 to move. The motion of the wire-winding plate 21 drives the wire holder 30 to move. The motion of the wire holder 30 drives the wire electric cylinder 32, the wire rod 33, and the second wire-passing ring 34 to move. The metal wire is driven to penetrate and move in the U-shaped insulator 2 through the second wire-passing ring 34, and the wire is placed in the U-shaped insulator 2.

[0081] When winding the metal wire into the remaining U-shaped insulators 2, the motion of the wire-winding plate 21 will also drive the pneumatic limit slide bar 22 to move at the same time. The motion of the pneumatic limit slide bar 22 will drive the positioning slider 4 to move. When the motion of the positioning slider 4 squeezes the air supply area, the inflation valve 25 and the suction and discharge valve 29 are opened, and the suction and discharge valve 29 is closed. The gas in the air supply area will be squeezed into the annular folding line box 6 through the inflation pipe 24. When the air pressure in the annular folding line box 6 increases, under the action of the pressure, the folding line slide bar 23 will move towards one side of the U-shaped insulator 2, so that the folding line slide bar 23 moves between the two U-shaped insulators 2 of the necklace. Then the positioning motor 10 is started. The output end of the positioning motor 10 will drive the positioning gear 11 to rotate. The rotation of the positioning gear 11 drives the annular internal gear 9 to rotate. The rotation of the annular internal gear 9 drives the positioning disc 8 to rotate. The rotation of the positioning disc 8 drives the positioning component 002 to rotate. By the rotation of the positioning component 002, the stator body 1 and the U-shaped insulator 2 are driven to move. Under the movement of the U-shaped insulator 2, the metal wire will be driven to move. And blocked by the folding line slide bar 23, the metal wire will be bent on one side of the U-shaped insulator 2. After the next U-shaped insulator 2 moves to one side of the wire groove to be wound, the inflation valve 25 is closed, the supply and discharge valve 27 is opened, and the power motor 20 is started again. The metal wire is driven by the second wire-passing ring 34 to wind the U-shaped insulator 2. In this way, by reciprocating in turn, with the cooperation of the positioning component 001 and the pneumatic wire-winding component 003, the winding of the metal wire in the U-shaped insulator 2 can be realized. On the contrary, through the movement of the positioning slider 4, the gas in the annular folding line box 6 can also be pumped into the pneumatic positioning cylinder 3, so that the folding line slide bar 23 shrinks into the annular folding line box 6.

[0082] During the process of winding the metal wire, through the contact between the annular broken line box 6 and the U-shaped insulator 2, it can effectively prevent the metal wire from overflowing from the U-shaped insulator 2. When the metal wire wound in the U-shaped insulator 2 gradually increases, the wire electric cylinder 32 can be started, and the output end of the wire electric cylinder 32 drives the wire rod 33 and the wire threading ring two 34 to move, so as to adjust the position of the wire threading ring two 34.

[0083] It should be supplemented that a wire pulling assembly is also arranged on one side of the power frame 17 for pulling the metal wire to be wound. The wire pulling assembly includes a wire pulling frame 35, a wire pulling roller 36, a wire pulling gear 37 and a wire pulling motor 38. The wire pulling frame 35 is arranged on one side of the power frame 17. There are two wire pulling rollers 36, and the wire pulling rollers 36 are rotatably arranged on the wire pulling frame 35. A wire pulling cavity is formed between the two wire pulling rollers 36 for pulling the metal wire to be wound. There are two wire pulling gears 37, and the wire pulling gears 37 correspond to the wire pulling rollers 36 one by one. The wire pulling gears 37 are arranged on one side of the wire pulling rollers 36, and the two wire pulling gears 37 are meshed with each other.
