[0036] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "plurality" means two or more, and "several" means one or more, unless otherwise specifically defined.

[0037] refer to Figures 1 to 3 The embodiment of the present invention provides a welding fixture for the welding end of a flat wire motor, comprising a support ring 1, a plurality of clamping female parts 2, a plurality of clamping male parts 3 adapted to the clamping female parts 2, and a rotating assembly 4.

[0038] In this embodiment, 24 clamping female parts 2 and 24 clamping male parts 3 are used, and the clamping female parts 2 and the clamping male parts 3 are located in the same plane. All the clamping female parts 2 and all the clamping male parts 3 are distributed in a circumferential array. At the same time, all the clamping female parts 2 and all the clamping male parts 3 are arranged at intervals. In addition, all the clamping female parts 2 and all the clamping male parts 3 in this application are slidably installed on the support ring 1 in the radial direction. A through hole 5 is formed between any clamping female part 2 and any adjacent clamping male part 3, which can allow a group of flat wire terminals to pass through and has an adjustable length along the radial direction of the support ring 1. The above quantities are only used to explain the technical solution in this embodiment, and are not used to limit the quantity and the technical solution of this embodiment, the same below. The through hole 5 with adjustable length in the radial direction can ensure that the welding fixture is adaptable to flat wire terminals of different models. At the same time, compared with the existing technology, it can ensure that the flat wire terminals can be quickly inserted into the through hole 5, thereby reducing the requirements for manpower and making the operation more convenient.

[0039] In this application, a rotating assembly 4 is mounted on the support ring 1 and is used to drive any clamping female component 2 and any clamping male component 3 to slide in opposite directions, thereby radially clamping and tightening each set of flat wire terminals within the through-hole 5. Similarly, during the release operation, all clamping female components 2 and all clamping male components 3 slide in opposite directions under the action of the rotating assembly 4, allowing each set of flat wire terminals to be removed from the through-hole 5. Compared to existing clamping methods, this solution significantly simplifies the clamp structure, resulting in a simpler structure and greater practicality.

[0040] In this embodiment, the support ring 1 is provided with 48 sliding slots 6 arranged in a circumferential array. The sliding slots 6 are used to slideably mount the clamping female components 2 and the clamping male components 3. The sliding slots 6 extend in the same radial direction as the support ring 1. This arrangement ensures that the clamping female components 2 and the clamping male components 3 clamp the flat wire terminals in the radial direction of the support ring 1, thereby resolving the issue of uneven flat wire stacking. Existing welding fixtures typically stack the flat wires circumferentially before welding them. Due to the lack of an effective clamping and positioning mechanism, radial gaps easily form between the flat wires. This uneven stacking severely impacts welding quality, resulting in unstable weld joint strength and conductivity, which in turn affects the overall performance of the flat wire motor. In this embodiment, radial compression of the flat wire terminals significantly improves contact between the welded flat wire terminals, significantly reducing the gap ratio between the flat wires and the welding defect rate. This also addresses the difficulty in ensuring welding quality: due to factors such as uneven flat wire stacking and complex fixture structures, existing welding fixtures struggle to maintain consistent welding quality. During the welding process, defects such as cold joints and leaky welds are prone to occur. These defects can cause the flat wire motor to malfunction during operation, reducing the reliability and service life of the product. This solution avoids these problems by extruding in the radial direction, thereby effectively ensuring the consistency of welding quality.

[0041] In this embodiment, a fixing device 7 is further included, which is arranged at the center of the support ring 1. A gap is formed between the support ring 1 and the fixing device 7 to facilitate the length adjustment of the through hole 5. The fixing device 7 is used for sliding and plugging installation of each clamping female component 2 and each clamping male component 3. The plug-in cooperation between the clamping female component 2 and the clamping male component 3 and the fixing device 7 can ensure the stability of the operation of the clamping female component 2 and the clamping male component 3, and can avoid the deviation of the clamping female component 2 and the clamping male component 3 in the axial direction, thereby ensuring that the flat wire terminal can be installed in the through hole 5. At the same time, it is ensured that the extrusion force on the flat wire terminal is greater and the force in the axial direction is more uniform, avoiding the existence of gaps between adjacent flat wires.

[0042] In this embodiment, an inserting hole is formed on the edge of the fixing device 7. The extending direction of the inserting hole is the same as the radial direction of the support ring 1 and is adapted to each clamping female component 2 and each clamping male component 3. This can effectively ensure the stability of each clamping female component 2 and each clamping male component 3.

[0043] In this embodiment, each clamping female component 2 includes a first slide 8 and a female clamp 9 mounted on the first slide 8. A first needle bearing 10 is provided at one end of the first slide 8 away from the center of the support ring 1, and a first insertion portion is provided at the other end of the first slide 8 to slideably engage with the insertion hole.

[0044] In one embodiment of this embodiment, the first sliding plate 8 is installed between the support ring 1 and the rotating assembly 4. In this case, a gap is formed between the first sliding plate 8 and the female clip 9 to accommodate the support ring 1. The fixing bolts used to attach the first sliding plate 8 and the female clip 9 are also sliding members that can slide within the sliding groove 6. The first needle roller bearing 10 slides in conjunction with the rotating assembly 4.

[0045] In one embodiment of the present invention, the first slide plate 8 is installed in the sliding groove, and the first needle bearing 10 slides in cooperation with the rotating assembly 4. At this time, the side edge of the first slide plate 8 is in sliding cooperation with the sliding groove 6.

[0046] In one case of this embodiment, the first sliding plate 8 is installed on the other side of the support ring 1 opposite to the rotating component 4, and the first needle bearing 10 passes through the sliding groove 6, slides with the sliding groove 6, and slides with the rotating component 4.

[0047] In this embodiment, each male clamping member 3 includes a second slide 11 and a male clamping piece 12 mounted on the second slide 11. A second needle bearing 13 is provided at one end of the second slide 11 away from the center of the support ring 1. The other end of the second slide 11 is provided with a second insertion portion that slidably engages with the insertion hole.

[0048] In one embodiment of this embodiment, the second slide 11 is installed between the support ring 1 and the rotating assembly 4. In this case, a gap is formed between the second slide 11 and the male clip 12 to accommodate the support ring 1. The fixing bolts used to attach the second slide 11 and the male clip 12 are also sliding members that can slide within the sliding groove 6. The second needle roller bearing 13 slides in conjunction with the rotating assembly 4.

[0049] In one embodiment of the present invention, the second slide plate 11 is installed in the sliding groove, and the second needle bearing 13 slides in cooperation with the rotating assembly 4. At this time, the side edge of the second slide plate 11 is in sliding cooperation with the sliding groove 6.

[0050] In another situation of this embodiment, the second sliding plate 11 is installed on the other side of the support ring 1 opposite to the rotating component 4, and the second needle bearing 13 passes through the sliding groove 6, slidingly cooperates with the sliding groove 6, and slides with the rotating component 4.

[0051] In this embodiment, the female clamp 9 is provided with a first clamping portion forming a through hole 5 at one end near the center of the support ring 1. The male clamp 12 is provided with a second clamping portion forming a through hole 5 at one end near the center of the support ring 1. The clamping portion and the first clamping portion form a through hole 5 in the radial direction of the support ring 1. The first clamping portion forms a first convex structure for radially squeezing the flat wire segment outward. The second clamping portion forms a second convex structure for radially squeezing the flat wire segment inward. The combination of the first and second convex structures allows the flat wire segment to be squeezed tightly in the radial direction, thereby resolving the technical problem in this application.

[0052] In this embodiment, the rotating assembly 4 includes a rotating ring, a meshing tooth provided on the outer edge of the rotating ring, and a driving assembly for driving the rotating ring. 24 first oblique sliding grooves 14 and 24 second oblique sliding grooves 15 are evenly distributed along the circumference of the rotating ring. Each first needle roller bearing 10 is provided in each first oblique sliding groove, and each second needle roller bearing 13 is provided in each second oblique sliding groove. The extension direction of the first oblique sliding groove 14 intersects with the extension direction of the second oblique sliding groove 15. Any adjacent first sliding groove and second sliding groove are staggered in the radial direction of the rotating ring. The driving assembly includes a T-type screw rod 16, a sliding block mounted on the T-type screw rod 16 and meshing with the meshing tooth, and a servo motor for driving the T-type screw rod 16.

[0053] The operating principle and operation steps of the welding fixture for flat wire motor flat wire terminals in this application are as follows:

[0054] Flat wire terminal insertion:

[0055] The flat wire terminals are passed in groups through the through holes 5 formed between the clamping female part 2 and the clamping male part 3. Since the through holes 5 are adjustable in length along the radial direction of the support ring 1, they can accommodate flat wire terminals of different specifications.

[0056] Clamping operation:

[0057] The servo motor is started, and the servo motor drives the T-type screw rod 16 to rotate.

[0058] The rotation of the T-shaped screw rod 16 drives the sliding block to move. Since the sliding block is meshed with the teeth of the rotating ring, the rotating ring rotates along with the movement of the sliding block.

[0059] When the rotating ring rotates, due to the special setting of the first oblique sliding groove 14 and the second oblique sliding groove 15, the first needle roller bearing 10 and the second needle roller bearing 13 will slide in the first oblique sliding groove 14 and the second oblique sliding groove 15 respectively, thereby driving the clamping female part 2 and the clamping male part 3 to slide in opposite directions.

[0060] The relative sliding of the female clamping member 2 and the male clamping member 3 causes each set of flat wire terminals to be clamped tightly together within the through-hole 5, subjecting them to different clamping forces. For example, the female clamping member 2 slides toward the center while the male clamping member 3 slides outward, or vice versa. This tightly clamps the flat wire terminals, significantly reducing gaps between the flat wires and improving welding quality.

[0061] Welding operation:

[0062] After the flat wire terminals are clamped, welding equipment can be used to perform welding operations on the flat wire terminals. Since the flat wire terminals are evenly clamped, the welding quality can be effectively guaranteed, reducing defects such as cold welding and leaking welding.

[0063] Release operation:

[0064] After welding is completed, the servo motor is started in reverse to rotate the rotating ring in the reverse direction, driving the clamping female part 2 and the clamping male part 3 to return to the initial position, loosening the flat wire terminal to facilitate the removal of the welded parts.

[0065] The above is only a specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with this technical field can easily think of changes or replacements within the technical scope disclosed in this application, which should be covered by the scope of protection of the present application.
