[0001] The invention relates to the technical field of insulation winding of motor stator ends, and in particular to an interphase insulation winding device for stator end windings of a generator. Background Art

[0002] The interphase insulation device of the generator stator end winding is an insulation device between the end windings of the generator stator, which is used to ensure electrical isolation between the phase windings to prevent short circuits and faults. This device is usually made of insulating materials and can effectively isolate the phase windings to prevent current leakage and short circuits between them, thereby ensuring the safe operation of the generator.

[0003] Nowadays, most common terminal end winding interphase insulation devices are to wind the metal wire into a willow on the outside, place the insulating paper inside the stator, and manually place the metal wire in the insulating paper of the motor stator so that the insulating paper wraps the wound metal wire. However, most traditional winding devices cannot be directly wound at the end of the motor stator. The metal wire wrapped with the insulating paper is easily broken due to the easy breakage of the insulating paper. When installed at the end of the motor stator, it is easy to break and cause leakage. In addition, the manual work efficiency is low.

[0015] The working principle and beneficial effects of the present invention are: 1. In the present invention, when winding the metal wire in the stator body, the U-shaped insulator is placed in the corresponding insulating groove, and the positioning slide bar is pulled, and the anti-slip positioning block clamps the stator body under the rebound of the positioning spring. When multiple positioning springs are evenly stressed, the position of the positioning slide bar is fixed by tightening the positioning bolt, so that the position of the stator body can be fixed, so that the power reciprocating screw rod is located in the middle position of the stator body. Compared with the prior art, by arranging the U-shaped insulator to replace the insulating paper, it is not only firmly arranged, but also not easy to be damaged; 2. In the present invention, when winding the metal wire, one end of the metal wire to be wound is fixed on the U-shaped insulator corresponding to the insulating groove through the wire pulling cavity, the first threading ring and the second threading ring in sequence. When threading in the U-shaped insulator, the power motor is started, and the power motor drives the power reciprocating screw to rotate. The rotation of the power reciprocating screw causes the power ball nut group to perform linear reciprocating motion. The movement of the power ball nut group drives the winding plate to move. The movement of the winding plate drives the wire rack to move. The movement of the wire rack drives the wire electric cylinder, the wire rod and the second threading ring to move. The metal wire is driven to move through the U-shaped insulator through the second threading ring, and the wire is placed in the U-shaped insulator. 3. In the present invention, when the metal wire is wound into the remaining U-shaped insulators, the movement of the winding plate will also drive the pneumatic limit slide bar to move, and the movement of the pneumatic limit slide bar will drive the positioning slide bar to move. When the movement of the positioning slide bar squeezes the air supply area, the inflation valve and the suction and exhaust valve are opened, and the suction and exhaust valve is closed. The gas in the air supply area will be squeezed into the annular folding box through the inflation tube. When the air pressure in the annular folding box increases, the folding slide bar will move toward one side of the U-shaped insulator under the action of pressure, so that the folding slide bar moves to between the two connected U-shaped insulators, and then the positioning motor is started, and the output end of the positioning motor will drive the positioning gear to rotate, and the rotation of the positioning gear drives the annular internal gear to rotate, and the rotation of the annular internal gear drives the positioning The disk rotates, and the rotation of the adjustment disk drives the positioning assembly to rotate. The rotation of the positioning assembly drives the stator body and the U-shaped insulator to move. The movement of the U-shaped insulator drives the metal wire to move, and the metal wire will be bent on one side of the U-shaped insulator under the obstruction of the folding line slide rod. After the next U-shaped insulator moves to one side of the wire groove, the inflation valve is closed, the supply and exhaust valve is opened, and the power motor is started again to drive the metal wire to wind around the U-shaped insulator through the threading ring 2. This is repeated in sequence. With the cooperation of the adjustment assembly and the pneumatic winding assembly, the winding of the metal wire in the U-shaped insulator can be realized. Conversely, the movement of the positioning slider can also pump the gas in the annular folding box into the pneumatic positioning cylinder, so that the folding line slide rod is retracted into the annular folding box. 4. In the process of winding the metal wire, the present invention can effectively prevent the metal wire from overflowing from the U-shaped insulator through the contact between the annular wire folding box and the U-shaped insulator. When the metal wire wound in the U-shaped insulator gradually increases, the wire electric cylinder can be started to drive the wire rod and the second threading ring to move through the output end of the wire electric cylinder, so as to adjust the position of the second threading ring; 5. The present invention, when threading the wire, starts the wire drawing motor, and the output end of the wire drawing motor drives the wire drawing roller connected thereto to rotate. Under the meshing of the wire drawing gear, the wire drawing roller drives the metal wire to move, and the metal wire is transported to realize the winding of the metal wire. After the winding of the metal wire is completed, the insulating material is also wound around the portion of the metal wire exposed on one side of the electronic stator to complete the winding operation of the wire.
