Thus, when the phrases "in one embodiment" or "in some embodiments" appear in various places throughout this specification, not all references are to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0042] See also Figure 2 、 Figure 4 and Figure 5 , the winding welding tool provided in the embodiment of the present application is now described. The winding welding tool includes a tool base 1, a first wire clamping plate 2, a second wire clamping plate 3 and a clamping adjustment unit 4. The tool base 1 is roughly annular in structure, and the tool base 1 can be sleeved on the stator 6. The hollow position of the tool base 1 can allow the flat wire 61 on the stator 6 to pass through. One end of the first wire clamping plate 2 is rotatably mounted on the tool base 1, and a first wire clamping hole 21 is provided on the first wire clamping plate 2. The first wire clamping hole 21 can allow the flat wire 61 to pass through. One end of the second wire clamping plate 3 is rotatably mounted on the tool base 1, and a second wire clamping hole 31 is provided on the second wire clamping plate 3. The second wire clamping hole 31 is arranged in alignment with the first wire clamping hole 21, and the second wire clamping hole 31 can allow the flat wire 61 to pass through, that is, the flat wire 61 can pass through the first wire clamping hole 21 and the second wire clamping hole 31 respectively. Among them, the first wire clamping plate 2 and the second wire clamping plate 3 can be roughly fan-shaped structures, and the first wire clamping plate 2 can be arranged above the second wire clamping plate 3. The clamping adjustment unit 4 connects the other end of the first wire clamping plate 2 and the other end of the second wire clamping plate 3, and the clamping adjustment unit 4 can drive the first wire clamping plate 2 and the second wire clamping plate 3 to rotate. When the clamping adjustment unit 4 drives the first wire clamping plate 2 and the second wire clamping plate 3 to rotate closer, the first wire clamping hole 21 and the second wire clamping hole 31 are close to each other to clamp the flat wire 61; when the clamping adjustment unit 4 drives the first wire clamping plate 2 and the second wire clamping plate 3 to rotate away, the first wire clamping hole 21 and the second wire clamping hole 31 are away from each other to release the clamping of the flat wire 61. In this way, by driving the rotation of the first wire clamping plate 2 and the second wire clamping plate 3 by the clamping adjustment unit 4, directional clamping of the local flat wire 61 can be achieved, the clamping effect of the flat wire 61 is improved, and the welding quality is thereby improved.

[0043] In one embodiment, see Figure 3 As a specific embodiment of the winding welding tooling provided in the embodiment of the present application, the clamping adjustment unit 4 includes a first positioning seat 41 installed on the other end of the first clamping plate 2, a second positioning seat 42 installed on the other end of the second clamping plate 3, and an adjusting screw 43 connecting the first positioning seat 41 and the second positioning seat 42; the first positioning seat 41 is provided with a first screw hole 411 for the adjusting screw 43 to pass through, and the second positioning seat 42 is provided with a second screw hole 421 for the adjusting screw 43 to pass through. Specifically, the other end of the first clamping plate 2 and the other end of the second clamping plate 3 are spaced apart, so that sufficient avoidance space can be provided for the rotation of the first clamping plate 2 and the second clamping plate 3. In this structure, through the rotation of the adjusting screw 43, the adjusting screw 43 cooperates with the first screw hole 411 and the second screw hole 421 respectively, which can drive the first clamping plate 2 and the second clamping plate 3 to rotate, so that the first clamping hole 21 and the second clamping hole 31 can be moved closer to or farther away from each other.

[0044] In one embodiment, see Figure 3 As a specific embodiment of the winding welding tool provided in the embodiment of the present application, the clamping adjustment unit 4 also includes a locking nut 44 mounted on the adjusting screw 43. The locking nut 44 is located between the first positioning seat 41 and the second positioning seat 42. In this structure, the locking nut 44 can be rotated on the adjusting screw 43 to adjust the installation position. The locking nut 44 can respectively cooperate with the first positioning seat 41 and the second positioning seat 42 to resist. This prevents the adjusting screw 43 from loosening and affecting the effectiveness of the first clamping hole 21 and the second clamping hole 31 in clamping the flat wire 61.

[0045] In one embodiment, see Figure 3 As a specific embodiment of the winding welding tool provided in the embodiment of the present application, there are two locking nuts 44, which are respectively installed on the adjusting screw 43, and the two locking nuts 44 are arranged between the first positioning seat 41 and the second positioning seat 42. In this structure, when the first clamping plate 2 and the second clamping plate 3 are rotated into place and the first clamping hole 21 and the second clamping hole 31 cooperate to clamp the flat wire 61, by adjusting the positions of the two locking nuts 44, that is, one locking nut 44 cooperates with the first positioning seat 41 to resist, and the other locking nut 44 cooperates with the second positioning seat 42 to resist, it can further prevent the adjusting screw 43 from loosening and affecting the clamping effect of the flat wire 61.

[0046] In some embodiments, the clamping adjustment unit 4 may also be a finger cylinder, and both ends of the finger cylinder may be connected to the first positioning seat 41 and the second positioning seat 42 respectively, which is not the only limitation here.

[0047] In one embodiment, see Figure 2 、 Figure 4 and Figure 5 As a specific embodiment of the winding welding fixture provided in the present application, a first positioning hole 22 is defined in the center of the first clamping plate 2, into which a positioning guide rod (not shown) is installed. A second positioning hole 32 is defined in the center of the second clamping plate 3, through which the positioning guide rod is respectively inserted. This structure allows the first clamping plate 2 and the second clamping plate 3 to rotate using the positioning guide rod as their respective axes, thereby improving the reliability of their rotation.

[0048] In one embodiment, see Figures 4 to 6 As a specific embodiment of the winding welding tool provided in the embodiment of the present application, a base 11, a top seat 12 connected to the base 11, and a mounting guide rod 13 mounted on the base 11 are installed on the tool base 1. A receiving groove 14 is formed between the base 11 and the top seat 12. One end of the first clamping plate 2 and one end of the second clamping plate 3 respectively extend into the receiving groove 14, and the mounting guide rod 13 is arranged in the receiving groove 14; a first opening 23 for the mounting guide rod 13 to pass through is formed on the first clamping plate 2, a second opening 33 for the mounting guide rod 13 to pass through is formed on the second clamping plate 3, and a third opening 121 for the mounting guide rod 13 to extend into is formed on the top seat 12. With this structure, the rotation of the first clamping plate 2 and the second clamping plate 3 can be limited by the receiving groove 14 formed between the base 11 and the top seat 12. By passing the guide rod 13 through the first opening 23 and the second opening 33, and extending into the third opening 121, the first clamping plate 2 and the second clamping plate 3 can be rotated and the rotation of the first clamping plate 2 and the second clamping plate 3 can be limited. The third opening 121 allows the guide rod 13 to be avoided.

[0049] In one embodiment, see Figures 4 to 6 The number of mounting guide rods 13 can be two, with the two mounting guide rods 13 installed on the base 11 at intervals. Correspondingly, there are two first openings 23 on the first clamping plate 2, two second openings 33 on the second clamping plate 3, and two third openings 121 on the top seat 12. The two mounting guide rods 13 pass through the two first openings 23 and the two second openings 33, respectively, and extend into the two third openings 121, respectively. This structure, by providing two mounting guide rods 13 and sleeved on the first and second clamping plates 2 and 3, improves the reliability of the reciprocating rotation of the first and second clamping plates 2 and 3, and prevents positional offset.

[0050] In one embodiment, see Figure 6As a specific embodiment of the winding welding tool provided in the embodiment of the present application, a positioning groove 111 is formed on the base 11, and the top base 12 is installed in the positioning groove 111. This structure can achieve the positioning and installation of the top base 12 on the base 11 through the positioning groove 111, thereby improving the alignment and installation accuracy between the top base 12 and the base 11.

[0051] In one embodiment, see Figure 1 and Figure 7 As a specific embodiment of the winding welding tool provided in the embodiment of the present application, the winding welding tool also includes a protective cover 5 provided on the tool base 1, and the protective cover 5 is respectively provided with a first avoidance hole 51 for the clamping adjustment unit 4 to pass through and a second avoidance hole 52 arranged in alignment with the first wire clamping hole 21. In this structure, the first avoidance hole 51 can be used to avoid the clamping adjustment unit 4, so that the clamping adjustment unit 4 can be extended to facilitate manual adjustment. The second avoidance hole 52 can be used to avoid the first wire clamping hole 21 and the second wire clamping hole 31, so that the welding module can pass through the second avoidance hole 52 to achieve welding of the flat wire 61. The protective cover 5 can play a shielding and protective role to avoid damage to the tool base 1 and other flat wires 61 during the welding process.

[0052] In one embodiment, see Figure 1 and Figure 7 The protective cover 5 is further provided with a third avoidance hole 53. The third avoidance hole 53 is aligned with the installation guide rod 13, thereby avoiding the installation guide rod 13. The number of the third avoidance holes 53 is the same as the number of the installation guide rod 13. In the embodiment of the present application, the number of the third avoidance holes 53 can be two.

[0053] In one embodiment, see Figure 2 As a specific embodiment of the winding welding tool provided in an embodiment of the present application, the winding welding tool further includes an alignment plate 15 mounted on the tool base 1, with alignment holes 151 defined in the alignment plate 15. This structure, through the alignment holes 151 in the alignment plate 15, improves the alignment accuracy between the winding welding tool and the welding machine, thereby contributing to improved welding quality. The number of alignment plates 15 can be two, and the two alignment plates 15 can be mounted at either end of the tool base 1, further improving the alignment accuracy between the winding welding tool and the welding machine.

[0054] The present application also provides a welding machine including the winding welding fixture provided by any of the above embodiments. In this structure, the welding machine using this winding welding fixture drives the rotation of the first clamping plate 2 and the second clamping plate 3 via the clamping adjustment unit 4, thereby achieving directional clamping of a portion of the flat wire 61, improving the clamping effect of the flat wire 61 and thereby enhancing welding quality.

[0055] The above description is merely an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
