[0027] The following is a detailed description of the positioning tool for welding motor enameled wires according to an embodiment of the utility model with reference to the accompanying drawings.

[0028] like Figure 1-Figure 3 As shown, the positioning tool for welding the motor enameled wire according to the embodiment of the utility model includes: a base 1 and a positioning seat 2; the base 1 is used to place the iron core, the positioning seat 2 is a tubular structure, the positioning seat 2 is sleeved on the iron core, the lower surface of the positioning seat 2 is in contact with the upper surface of the base 1, and the inner surface of the positioning seat 2 is provided with a plurality of positioning plates 21 along the circumferential direction, and a plurality of grooves 22 are formed on one side of the positioning plate 21, and the plurality of grooves 22 are arranged at intervals along the radial direction of the iron core, and the positioning plate 21 is rotatably connected to the positioning seat 2, and when the positioning plate 21 is in a horizontal state, the plurality of enameled wire welding ends on the iron core are respectively located in the plurality of grooves 22, and when the positioning plate 21 is in a vertical state, the enameled wire welding ends are separated from the grooves 22 to facilitate the positioning seat 2 to be inserted into or detached from the iron core.

[0029] A plurality of rows of enameled wire welding ends are arranged on the iron core along the circumferential direction, and each row of enameled wire welding ends is arranged along the radial direction of the iron core.

[0030] In this embodiment, the number of positioning plates 21 is the same as the number of rows of enameled wire welding ends, and the number of grooves 22 on the positioning plates 21 is the same as the number of enameled wire welding ends in each row. The iron core is placed on the base 1, and the positioning seat 2 is sleeved on the iron core. At this time, the positioning plate 21 is in a vertical state, so that the entire row of enameled wire welding ends can enter between the two positioning plates 21. After the positioning seat 2 is sleeved on the iron core, the positioning plate 21 is rotated in the same direction to flip the positioning plate 21 to one side. At this time, a row of enameled wire welding ends on one side of the positioning plate 21 are respectively embedded in multiple grooves 22 on the positioning plate 21, thereby achieving unified positioning of the enameled wire welding ends on the iron core and ensuring the quality of welding. After the positioning is completed, the enameled wire welding ends on the iron core can be welded in sequence, reducing the pause time and improving the production speed. During the welding process, the same method is used to position the enameled wire welding ends on the next iron core, further reducing the welding pause time and improving the production speed.

[0031] A guide ring 31 is provided on the positioning seat 2, and the guide ring 31 is slidably connected to the positioning seat 2. A plurality of protrusions 32 are provided on the guide ring 31. The number of the plurality of protrusions 32 is the same as that of the positioning plate 21, and the positions correspond one to one. The guide ring 31 is used to drive the protrusions 32 to lift the positioning plate 21 or move away from the positioning plate 21.

[0032] In this embodiment, the guide ring 31 reciprocates along the central axis direction of the iron core. When the guide ring 31 moves upward, the protrusion 32 pushes up one side of the positioning plate 21, so that multiple positioning plates 21 are synchronously in a vertical state, which is convenient for installing or releasing the enameled wire welding end. After the enameled wire welding end is installed, the guide ring 31 is moved downward. At this time, the positioning plate 21 that is no longer restricted by the protrusion 32 can be flipped to one side to achieve the positioning of the enameled wire welding end.

[0033] The positioning seat 2 includes: a sleeve ring 23, a mounting ring 24 and a connecting frame; the inner surface of the sleeve ring 23 matches the outer surface size of the iron core, the guide ring 31 is slidably connected to the outer surface of the sleeve ring 23, the lower end of the sleeve ring 23 contacts the base 1, the positioning plate 21 is installed on the inner surface of the mounting ring 24, the inner diameter of the mounting ring 24 is larger than the outer diameter of the sleeve ring 23, the guide ring 31 moves between the inner diameter of the mounting ring 24 and the outer diameter of the sleeve ring 23, and the connecting frame is used to connect the sleeve ring 23 and the mounting ring 24.

[0034] In this embodiment, the inner surface of the sleeve ring 23 is slidably connected to the outer surface of the iron core, and the gap between the two is small to reduce deviation and facilitate the positioning of the welding end of the enameled wire by the positioning plate 21. The inner diameter of the mounting ring 24 is larger than the outer diameter of the sleeve ring 23 so that the protrusion 32 can contact the positioning plate 21 when it is upward, and the mounting ring 24 provides a moving space for the protrusion 32.

[0035] A guide groove 231 is formed on the outer surface of the sleeve ring 23 , and a guide block 311 is formed on the inner surface of the guide ring 31 . The guide block 311 slides in the guide groove 231 .

[0036] There are multiple guide grooves 231 , which are spaced apart along the circumferential surface of the sleeve ring 23 . The number of guide blocks 311 is the same as the number of guide grooves 231 , and they correspond one to one.

[0037] In this embodiment, the guide groove 231 guides the guide block 311 so that the guide ring 31 can move vertically back and forth, thereby preventing the guide ring 31 from rotating during the movement and ensuring the accuracy of the relative position between the protrusion 32 and the positioning plate 21.

[0038] The positioning plate 21 and the mounting ring 24 are connected by a guide shaft 26 , one end of the guide shaft 26 is fixedly connected to the other side of one end of the positioning plate 21 , and the other end of the guide shaft 26 is connected to the bearing of the mounting ring 24 .

[0039] In this embodiment, the central axis of the guide shaft 26 is arranged along the radial direction of the iron core, and the guide shaft 26 is arranged on one side of the positioning plate 21 to reduce the required space on one side of the positioning plate 21 when the positioning plate 21 is flipped, thereby reducing the height requirement between the positioning plate 21 and the iron core, thereby meeting the positioning of the shorter enameled wire welding end.

[0040] The connecting frame includes a bottom plate 251 and a side plate 252 . One side of the bottom plate 251 is connected to one side of the side plate 252 , the other side of the bottom plate 251 is connected to the bottom of the sleeve ring 23 , and the other side of the side plate 252 is connected to the mounting ring 24 .

[0041] In this embodiment, the bottom plate 251 is located below the guide ring 31 , and the side plate 252 is located outside the outer surface of the guide ring 31 to meet the connection between the sleeve ring 23 and the mounting ring 24 while avoiding interference with the guide ring 31 .

[0042] A shift block 312 is disposed on the guide ring 31 , and one end of the shift block 312 protrudes from the side plate 252 .

[0043] In this embodiment, the shifting block 312 is used to shift the guide ring 31 . There may be two shifting blocks 312 , which are disposed opposite to each other on the guide ring 31 .

[0044] The base 1 includes a chassis 11 and two arc frames 12. The two arc frames 12 are arranged opposite to each other and fixedly connected to the chassis 11. The upper surfaces of the two arc frames 12 are flat and used to support the sleeve ring 23. A support plate 121 is provided on the inner wall of the arc frame 12, and the support plate 121 is used to support the iron core.

[0045] The upper surface of the supporting plate 121 is higher than the upper surface of the bottom chassis 11 .

[0046] In this embodiment, there is a certain distance between the two arc-shaped frames 12. The upper surface of the support plate 121 is higher than the upper surface of the chassis 11. When the iron core is placed on the support plate 121, it has a certain distance from the upper surface of the chassis 11. Therefore, when placing the iron core, it is convenient for the staff to support their hands on the bottom of the iron core, avoiding the phenomenon of the iron core slipping when placing the iron core by clamping the circumferential surface of the iron core, ensuring that the hands of the staff are not squeezed, and improving the stability of the placement of the iron core.
