In the process of moving radially inward, the abutting head 20 first abuts against the second welding wire head 10, and then the abutting seat 19 continues to move radially inward and compresses the abutting spring 21, so that the abutting spring 21 drives the abutting head 20 to abut against the second welding wire head 10 through the elastic force, thereby preventing the abutting head 20 from over-pressing or false-pressing the second welding wire head 10.

[0116] The second handle component 25 is connected to the second driving member 24 and is used to drive the second driving member 24 to rotate. The second driving member 24 has a second clamping position and a second releasing position in the process of rotating;

[0117] When the second driving member 24 rotates to the second clamping position, the second driving member 24 drives the pressing component 4 to move radially to abut against the first welding wire head 6 in the corresponding hollow groove 2 through the cooperation of the pressing transmission groove 27 and the pressing transmission pin 28;

[0118] When the second driving member 24 rotates to the second loosening position, the second driving member 24 drives the pressing member 4 to move radially to disengage from the first welding wire head 6 through the cooperation of the supporting transmission groove 15 and the supporting transmission pin 17;

[0119] The second locking member 26 is connected to the second handle member 25, and is used to cooperate with the main body seat 1 when the second driving member 24 rotates to the second clamping position, so as to lock the position of the second handle member 25 relative to the main body seat 1, and further lock the position of the second driving member 24 relative to the main body seat 1, so that the pressing member 4 is kept in the state of abutting against the first welding wire head 6. Specifically, the second locking member 26 can be a second indexing pin, which is inserted into a second pin hole on the main body seat 1 when the second driving member 24 rotates to the second clamping position, so as to lock the position of the second handle member 25 relative to the main body seat 1. In the embodiment, the pressing transmission groove 27 and the pressing member 4 correspond one by one, and the second driving member 24 has an arc structure.

[0120] As shown in Figure 10 The pressing member 4 can include a pressing seat 29, a pressing head 30, and a pressing spring 31.

[0121] The pressing seat 29 is connected to the main body seat 1 in a radial sliding manner;

[0122] The pressing transmission pin 28 is connected to the pressing seat 29, so that the second handle member 25 drives the second driving member 24 to rotate, and further drives the pressing seat 29 to move radially;

[0123] The pressing head 30 is connected to the pressing seat 29 in a radial sliding manner and is used to abut against the first welding wire head 6.

[0124] The compression spring 31 is arranged between the compression seat 29 and the compression head 30 and is used to drive the compression head 30 to abut against the first welding wire head 6. Specifically, the compression head 30 is provided with a second waist-shaped groove 32, and the compression transmission pin 28 is matched in the second waist-shaped groove 32 so as to limit the stroke of the compression head 30 relative to the compression seat 29, thereby preventing the compression head 30 from slipping off the compression seat 29. In the embodiment, when the second driving member 24 rotates to the second clamping position, the second driving member 24 drives the compression seat 29 to move radially outward through the cooperation of the compression transmission groove 27 and the compression transmission pin 28. In the process of the radial outward movement of the compression seat 29, the compression head 30 first abuts against the first welding wire head 6, and then the compression seat 29 continues to move radially outward and compresses the compression spring 31, and then the compression spring 31 drives the compression head 30 to compress the first welding wire head 6 through the elastic force, so as to prevent the compression head 30 from over-pressing or false-pressing the first welding wire head 6.

[0125] Further specifically, the compression seat 29 comprises a seat body 33 and an adjusting screw 34, the compression head 30 is slidingly connected in the seat body 33, the compression transmission pin 28 is connected on the seat body 33, the adjusting screw 34 is connected on the seat body 33, one end of the compression spring 31 abuts against the compression head 30, and the other end of the compression spring 31 abuts against the adjusting screw 34, so as to adjust the compression amount of the compression spring 31 by screwing the adjusting screw 34. The compression head 30 is provided with a first pressing groove 35 for pressing the first welding wire head 6, and the abutting head 20 is provided with a second pressing groove 36 for pressing the second welding wire head 10.

[0131] When the second handle component 25 drives the second drive component 24 to rotate to the second release position, the second drive component 24 drives the clamping arm 37 to rotate through the cooperation of the drive groove 39 and the drive pin 38 until it disengages from the first terminal 8 on the busbar 7 in the first hollow groove.

Therefore, the clamping component 4 alone cannot press the first solder wire end 6 in the first hollow slot onto the corresponding first terminal 8. Thus, the clamping arm 37 is needed to press against the first terminal 8 on the busbar 7 in the first hollow slot, so that the clamping arm 37 and the corresponding clamping component 4 together press the first solder wire end 6 in the first hollow slot onto the corresponding first terminal 8. In this embodiment, the main body 1 is also connected to a first support base 40 and a second support base 41. The first support base 40 abuts against the busbar 7 placed in the second hollow slot to provide support for the busbar 7 in the second hollow slot, and the second support base 41 abuts against the busbar 7 placed in the third hollow slot to provide support for the busbar 7 in the third hollow slot.

[0139] The first driving mechanism 100 and the second driving mechanism 200 are connected to the mounting plate 43; specifically, the first welding wire head 6 and the second welding wire head 10 both extend into the hollow slot 2 in the mounting plate 43 when the positioning ring 42 is positioned and assembled on the stator assembly 5. In this embodiment, the supporting plate 3, the pressing component 4 and the abutting component 9 are all radially slidingly connected to the mounting plate 43, the first driving member 12 and the second driving member 24 are both rotationally connected to the mounting plate 43, the first pin hole and the second pin hole are both provided on the mounting plate 43, the first support seat 40 and the second support seat 41 are both connected to the mounting plate 43, and the clamping arm 37 is rotationally connected to the mounting plate 43.

[0140] As shown in Figures 1-3 The stator assembly 5 comprises a stator core, and a limiting groove 45 is arranged on the outer side wall of the stator core.

[0145] In summary, first, the main body seat 1 is positioned and assembled on the stator assembly 5, after being assembled in place, the first welding wire head 6 extends into the corresponding hollow groove 2, then the first driving mechanism 100 drives the sliding of the supporting plate 3 to extend into the corresponding hollow groove 2, then the busbar 7 is placed in the corresponding hollow groove 2 and held by the supporting plate 3 in the hollow groove 2, at this time, the first terminal 8 on the busbar 7 abuts against the corresponding first welding wire head 6. Then the second driving mechanism 200 drives the sliding of the pressing component 4 to abut against the first welding wire head 6 in the corresponding hollow groove 2, so as to press the first welding wire head 6 on the corresponding first terminal 8, then the first welding wire head 6 can be welded on the corresponding first terminal 8 by a welding device.
