[0029] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0031] As society pays increasing attention to environmental protection and sustainable development, new energy vehicles, as an important alternative to traditional fuel vehicles, are gradually becoming the mainstream of the automotive industry.

[0032] In new energy vehicles, the motor is a key power unit, and its performance directly impacts the vehicle's driving performance and energy efficiency. Motor stators using flat wire windings have a high copper fill factor, which improves the motor's power density. Flat wire windings typically have a welded end at one axial end of the stator, where adjacent flat wire ends are welded together. In the industry, this type of flat wire winding with a very small axial weld end is also known as X-Pin. As a key component of motors, X-Pin winding technology plays a vital role in improving motor performance and the development of new energy vehicles.

[0033] In order to ensure direct welding, a welding fixture is usually used to clamp the welding ends of adjacent flat wires. The welding fixture in the existing technology is generally clamped by screw drive, which requires manual screw tightening or tightening with a tightening gun, which is too inefficient and has high labor costs.

[0034] To solve the above technical problems, please refer to Figure 1 The present application provides a motor wire end welding clamping tool 100, which may include a tool base 110, a plurality of transmission rods 120 and a driving mechanism.

[0035] Specifically, the tooling base 110 is used for pre-positioning of the flat wire winding. The tooling base 110 is formed in a disc shape. The tooling base 110 may include a mounting seat 111, a functional ring seat 112 and a mounting cover 116. The mounting seat 111 is provided with a plurality of clamping holes 1111. The plurality of clamping holes 1111 are spaced apart around the central axis of the tooling base 110. The clamping holes 1111 are used for the flat wire to pass through. The functional ring seat 112 is sleeved on the radial outer side of the mounting seat 111. The mounting cover 116 is covered on the axial side of the functional ring seat 112. The edge of the mounting cover 116 extends out of the circumferential side wall of the functional ring seat 112.

[0036] Among them, see Figure 2 The functional ring seat 112 includes a plurality of guide channels, which are spaced apart in the circumferential direction of the functional ring seat 112 . The guide channels penetrate the functional ring seat 112 in the direction from the outer circumference of the functional ring seat 112 toward the inner circumference.

[0037] The plurality of transmission rods 120 correspond to the plurality of guide channels one by one. The transmission rods 120 are passed through the guide channels. One end of the transmission rod 120 extends out of the outer circumference of the functional ring seat 112 , and the other end extends out of the inner circumference of the functional ring seat 112 .

[0038] The driving mechanism is located on the circumferential outer side of the functional ring seat 112 and is arranged on the edge of the mounting cover 116. The driving mechanism may include a plurality of driving members 130. The plurality of driving members 130 are arranged at intervals on the circumference of the functional ring seat 112. The driving members 130 correspond one-to-one to the transmission rod 120. The driving members 130 are used to drive the transmission rod 120 to move in the direction from the outer circumference of the functional ring seat 112 toward the inner circumference.

[0039] In this way, the driving member 130 pushes the transmission rod 120, so that the transmission rod 120 moves toward the position to be welded until the copper wire is clamped at the position to be welded, thereby achieving an automatic clamping effect, improving the clamping efficiency during the welding process, and reducing labor costs.

[0040] Furthermore, the guide channel includes a first channel 113, a second channel 114 and a plurality of third channels 115 in sequence. One end of the first channel 113 passes through the outer circumference of the functional ring seat 112, and the other end is connected to the second channel 114. One end of the third channel 115 is connected to the second channel 114, and the other end passes through the inner circumference of the functional ring seat 112. The plurality of third channels 115 are spaced apart in the circumferential direction of the functional ring seat 112.

[0041] Please continue reading Figure 2 and Figure 3The transmission rod 120 can include a driving rod 121, a cross rod 122, and a plurality of clamping rods 123. The driving rod 121 is arranged in the first channel 113 and is in clearance fit with the first channel 113. One end of the driving rod 121 extends out of the outer circumferential surface of the functional ring seat 112, and the other end is rotationally connected with the cross rod 122. The cross rod 122 is arranged in the second channel 114 and is in clearance fit with the second channel 114. The clamping rod 123 corresponds to the third channel 115 one by one. The clamping rod 123 is arranged in the third channel 115 and is in clearance fit with the third channel 115. One end of the clamping rod 123 is rotationally connected with the cross rod 122, and the other end can extend out of the inner circumferential surface of the functional ring seat 112.

[0042] Specifically, please continue to refer to Figure 1 The driving member 130 is formed as an extension rod. The moving end of the extension rod can push the one end of the driving rod 121 extending out of the outer circumferential surface of the functional ring seat 112. The driving rod 121 pushes the cross rod 122 to move towards the central axis of the tool base 110. The cross rod 122 drives the plurality of clamping rods 123 to move towards the central axis of the tool base 110, until the clamping copper wire, thereby realizing the effect of automatic clamping and improving the efficiency of clamping in the welding process, without the need for additional manual intervention, thereby reducing labor costs.

[0043] Meanwhile, due to the differences in copper wire and tool processing, the clamping size of each group of copper wire is different. The driving rod 121 is in clearance fit with the first channel 113, the cross rod 122 is in clearance fit with the second channel 114, the clamping rod 123 is in clearance fit with the third channel 115, and the driving rod 121 is rotationally connected with the cross rod 122, and the cross rod 122 is rotationally connected with the clamping rod 123, so that the clamping rod 123 can be independently adjusted to a certain extent, thereby realizing independent clamping of each group of copper wire, avoiding the gap between the lap welding end surfaces, and meeting the requirements of laser welding.

[0044] In some embodiments of the present application, please refer to Figure 2 and Figure 3 The transmission rod 120 can include a driving rod 121, a cross rod 122, and three clamping rods 123. The driving rod 121 and the clamping rod 123 are located on both sides of the cross rod 122 in the width direction. The driving rod 121 is rotationally connected to the middle position of the cross rod 122 in the length direction (i.e., the extension direction of the cross rod 122). Two of the three clamping rods 123 are respectively rotationally connected to both ends of the cross rod 122, and the other is rotationally connected to the middle position of the cross rod 122 in the length direction.

[0045] In this way, when the driving member 130 pushes the driving rod 121, the clamping rod 123 abuts to the copper wire, and because the driving rod 121 is in clearance fit with the first channel 113, the cross rod 122 is in clearance fit with the second channel 114, and the clamping rod 123 is in clearance fit with the third channel 115, the driving rod 121 is rotationally connected with the cross rod 122, and the cross rod 122 is rotationally connected with the clamping rod 123, so that the cross rod 122 and the clamping rod 123 will rotate to a certain extent to meet the size difference of the copper wire clamped at different positions, so that each group of copper wire welding positions can be well clamped.

[0046] In some embodiments of the present application, the motor wire head welding and clamping tool 100 can further include a first rotating column 140, the driving rod 121 is provided with a first rotating hole, the cross rod 122 is provided with a second rotating hole matched with the first rotating hole, and the first rotating column 140 is arranged in the first rotating hole and the second rotating hole to realize the rotational connection between the driving rod 121 and the cross rod 122.

[0047] It can be understood that the rotational connection between the cross rod 122 and the clamping rod 123 can also be realized by the way of the rotating hole and the rotating column matched with each other.

[0048] In some embodiments of the present application, the first rotating column 140 can be fixedly connected with the driving rod 121, specifically, the first rotating column 140 includes a connecting flange and a column body, the column body is arranged in the first rotating hole, and the connecting flange is connected with the driving rod 121 by bolts or adhesion.

[0049] In some other embodiments of the present application, the first rotating column 140 can also be fixedly connected with the cross rod 122.

[0050] In some other embodiments of the present application, please refer to Figure 4 , the cross rod 122 can include a primary cross rod 1221, a plurality of secondary cross rods 1222 and a plurality of connecting cross rods 1223, the primary cross rod 1221 is rotationally connected with the driving rod 121, the secondary cross rod 1222 is rotationally connected with the clamping rod 123, one end of the connecting cross rod 1223 is rotationally connected with the primary cross rod 1221, and the other end is rotationally connected with the secondary cross rod 1222, the secondary cross rod 1222 corresponds to the connecting cross rod 1223 one by one, and the secondary cross rod 1222 is rotationally connected with the plurality of clamping rods 123.

[0051] Further, the secondary cross rod 1222 is rotationally connected with two clamping rods 123, the secondary cross rod 1222 extends in the circumferential direction of the functional ring seat 112, and the two clamping rods 123 are rotationally connected at both ends of the secondary cross rod 1222 in the extending direction.

[0052] It can be understood that the shape of the second channel 114 matches the shape of the primary crossbar 1221, the secondary crossbar 1222, and the connecting crossbar 1223, and is matched in clearance. Thus, by setting the crossbar 122 as the primary crossbar 1221, the secondary crossbar 1222, and the plurality of connecting crossbars 1223, the movement of the clamping rod 123 is more flexible, and is more suitable for matching the thickness of the copper wire at the welding position.

[0053] Specifically, taking the number of the plurality of clamping rods 123 as four as an example, when the crossbar 122 is only one crossbar 122, the movement of one crossbar 122 drives the movement of the four clamping rods 123, and the four clamping rods 123 mutually influence and restrict each other. When the crossbar 122 is the primary crossbar 1221, the two secondary crossbars 1222, and the two connecting crossbars 1223, one secondary crossbar 1222 corresponds to two clamping rods 123, and only the two clamping rods 123 mutually influence and restrict each other. Therefore, by setting the crossbar 122 as the primary crossbar 1221, the secondary crossbar 1222, and the connecting crossbar 1223, the movement of the clamping rod 123 is more flexible.

[0054] In some examples of the present application, the driving member 130 is provided with a pressure sensor for detecting the pressure borne by the driving member 130. It can be understood that the driving member 130 is set with a set pressure, and when the pressure borne by the driving member 130 reaches the set pressure, the driving member 130 stops, at which time the clamping rod 123 clamps the copper wire at the welding position.

[0055] It should be noted that, please refer to Figures 1 to 4 For the welding position of the flat wire winding, generally including 54 and 72, in the implementation process of the motor wire head welding and clamping tool 100 of the present application, for the flat wire winding of the 54 welding position, the transmission rod 120 can adopt the structure form of one driving rod 121, one crossbar 122, and three clamping rods 123, so that the number of the transmission rod 120 is 18, and the number of the driving member 130 is also 18.

[0056] For the flat wire winding of the 72 welding position, the transmission rod 120 can adopt the structure form of one driving rod 121, one crossbar 122, and four clamping rods 123, so that the number of the transmission member is also 18, and the number of the driving member 130 is also 18.

[0057] Thus, the above two kinds of flat wire windings only need to replace the corresponding mounting seat 111 and functional ring seat 112 in the welding process.
