Description

Technical Field

[0001] The utility model belongs to the technical field of manual stator wire insertion, and relates to a stator manual wire insertion auxiliary tool. Background Art

[0002] The stator is the stationary part of an electric motor or generator, which usually includes a stator core and windings. The U-shaped copper wire inside the stator is part of the stator winding and is usually used to form windings in the slots of the stator core. When power is applied, the magnetic field generated by these U-shaped copper wires interacts with the magnetic field of the rotor, thereby making the motor or generator run. In some cases, workers need to manually insert the U-shaped copper wires into the stator. Since the U-shaped wires need to be stacked layer by layer and need to be inserted into the corresponding wire slots, without external auxiliary devices, the efficiency of workers manually inserting the wires is low and prone to errors, which in turn affects work efficiency.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, a stator manual wire-insertion auxiliary tooling comprises a positioning disk 2 sleeved on the upper side of the iron core 1, and a plurality of guide shafts 5 are movably inserted in the positioning disk 2 in a ring array with the center of the positioning disk 2 as the center, and the upper end of the guide shaft 5 is connected to the wire-insertion disk 3, and the wire-insertion disk 3, the iron core 1 and the positioning disk 2 are coaxially arranged, and a plurality of wire-receiving rods 4 are inserted in a ring on the inner side of the wire-insertion disk 3. The position and number of the wire-receiving rods 4 inserted in the wire-insertion disk 3 are adjusted according to the position and number of the copper wires corresponding to the model of the iron core 1. One end of the wire-receiving rod 4 passes through the wire-insertion disk 3 and extends to the outside of the wire-insertion disk 3. A pull block 6 is slidably inserted at one end of the wire-receiving rod 4 located on the outer side of the wire-insertion disk 3, and the pull block 6 is provided with a first limiting component to prevent the pull block 6 from separating from the wire-receiving rod 4;

[0019] The guide shaft 5 is provided with a second limiting component located on the lower side of the positioning plate 2 .

[0020] After the wires are connected, the staff can use the second limiting component to limit the guide shaft 5 and the second limiting component to limit the guide shaft 5 to prevent the guide shaft 5 from moving during use, thereby ensuring the reliability of the manual wire plugging auxiliary tooling during use. After all the copper wires are connected, the staff can use the pull block 6 to move radially along the wire plugging disk 3. The wire supporting rod 4 is pulled outward to separate the wire supporting rod 4 from the U-shaped copper wire. Under the action of the first limiting component, the pulling block 6 cannot separate from the wire supporting rod 4, thereby preventing the staff from separating the pulling block 6 from the wire supporting rod 4 when pulling the wire supporting rod 4 through the pulling block 6. When the wire supporting rod 4 is removed, the staff can release the limit of the pulling block 6 by the first limiting component, so that the staff can remove the pulling block 6 from the wire supporting rod 4, and then the staff can pull the wire supporting rod 4 to separate it from the wiring tray 3, so that the staff can adjust the position of the wire supporting rod 4 on the wiring tray 3. After the wire supporting rod 4 is separated from the U-shaped copper wire, the staff presses all the U-shaped copper wires downward into the inside of the iron core 1 through external equipment, completing the wiring step of the iron core 1, thereby improving the work efficiency of the staff when manually wiring.

[0021] When the wire rod 4 is pulled to move, the horizontal side surface of the flat surface 401 slides along the wire drum 3. At the same time, the horizontal side surface fits the wire drum 3 to prevent the wire rod 4 from rotating in the wire drum 3, thereby ensuring the reliability of the wire rod 4 during use. When the wire rod 4 moves radially outward along the wire drum 3, the side surface of the flat surface 401 can move with the wire rod 4 and contact the inner side surface of the wire drum 3, thereby preventing the wire rod 4 from separating from the wire drum 3 when sliding.

[0022] In this embodiment, the pull block 6 is horizontally provided with a through hole 601 for inserting the wire-supporting rod 4, and a positioning screw hole 602 connected to the through hole 601 is provided on the lower side of the pull block 6. The first limiting component includes a positioning bolt 8 threadedly connected to the positioning screw hole 602. The upper end of the positioning bolt 8 can pass through the positioning screw hole 602 and abut against the flat section 401 of the wire-supporting rod 4. When in use, the staff rotates the positioning bolt 8 so that the end of the positioning bolt 8 always abuts against the flat section 401 of the wire-supporting rod 4. Under the action of friction, the pull block 6 is always fixedly connected to the wire-supporting rod 4, thereby preventing the pull block 6 from separating from the wire-supporting rod 4 during use, thereby ensuring the reliability of the pull block 6 during use.

[0023] 703 is provided on the side of the limit block 7 that is close to the inner side of the limit block 7. A gap is formed between the countersunk hole 702 and the fastening screw hole 703, and the upper and lower sides of the gap are connected to the outside world. Bolt 9, one end of the fastening bolt 9 is threadedly connected to the fastening screw hole 703. When adjusting the height of the wiring reel 3, the staff pulls the guide shaft 5 up and down in the positioning disk 2. When it moves to a suitable height for the wiring reel 3, the staff moves the limit block 7 to fit the lower side of the positioning disk 2, and then connects it to the mounting hole 701 and the mounting screw hole through the bolt thread, so that the limit block 7 is connected and fixed to the positioning disk 2. After that, the staff rotates the fastening bolt 9 to reduce the gap between the countersunk hole 702 and the fastening screw hole 703, and clamps the guide shaft 5 in the limit block 7, thereby preventing the guide shaft 5 from moving up and down during use under the action of friction, thereby ensuring the stability of the wiring auxiliary tooling during operation.

[0024] In this embodiment, the upper side surfaces of the positioning disk 2 and the wire plugging disk 3 are both in a circular array with scales, and the scales on the upper side surfaces of the positioning disk 2 and the wire plugging disk 3 correspond one to one, and the scales are all facing the center of the iron core 1. When the positioning disk 2 is prevented, the scales are made to correspond to the wire groove 101 on the iron core 1, thereby improving the convenience of the staff in adjusting the position of the wire supporting rod 4, so that when the U-shaped copper wire is laid on the wire supporting rod 4, the two lower ends of the U-shaped copper wire are both located in the wire groove 101.

[0025] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
