Description

Technical Field

[0001] The present invention belongs to the field of stator processing equipment, and in particular relates to a clamping and shaping device and process for an Xpin stator. Background Art

[0002] Xpin stator technology is an advanced motor winding design, named after its unique winding structure: interlaced spiral windings. Compared to traditional winding structures, the Xpin stator utilizes a more compact and organized arrangement, effectively increasing the winding fill factor and reducing the winding resistance and inductance, thereby improving the motor's efficiency and power density. The Xpin stator design draws inspiration from the helical structure found in biology. By incorporating the helical shape into the motor windings through biomimetic methods, the result is a more compact and efficient arrangement.

[0003] However, before welding the Xpin stator, it needs to be clamped and shaped to ensure that the adjacent layers of copper wires are in close contact to ensure the subsequent welding effect.

Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0035] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "disposed" should be understood in a broad sense. For example, they may refer to fixed connection or disposition, detachable connection or disposition, or integral connection or disposition.

The middle part of the assembly stand 2 is provided with a clamping and shaping component 3 for clamping and shaping adjacent layers of copper wires of the stator 10. The inner layer of the stator 10 is also provided with an inner support cylinder 8 for clamping two adjacent layers of copper wires. It should be noted that the jacking and rotating component 9 is a prior art. The jacking and rotating component 9 used in this embodiment is the "jacking and rotating component 9" in the invention patent with application number 202411517784.5 (a core feeding and detection device). Its structural principle is the same and will not be repeated here. Figure 3 As shown, during operation, the stator 10 is placed on the top of the lifting and rotating assembly 9. The lifting and rotating assembly 9 can achieve the purpose of lifting and rotating the stator 10 to cooperate with the work of clamping and welding the copper wire.

[0038] Detailed, such as Figure 2 As shown, the clamping and shaping assembly 3 is installed on the front side of the vertically moving linear module III6, so that the pneumatic clamping jaw 304 can move up and down to achieve the purpose of clamping and shaping. The linear module III6 is installed on the top of the linear module II5 that moves left and right.

The motor mounting plate 302 is connected to the moving end of the linear module III6 through a moving plate 303. The moving plate 303 is also equipped with a pneumatic clamp 304 that is driven to rotate by the servo reduction motor 301. The pneumatic clamp 304 is movably installed on the clamp mounting seat 309 to facilitate subsequent disassembly and maintenance. The servo reduction motor 301 and the clamp mounting seat 309 are connected through a bearing mounting seat 307 installed on the moving plate 303. The bearing mounting seat 307 realizes the connection between the output end of the servo reduction motor 301 and the clamp mounting seat 309 through the bearing 308 installed inside, thereby completing the work of driving the pneumatic clamp 304 to rotate by the rotation of the servo reduction motor 301.

[0040] Detailed, such as Figure 4-6As shown, the clamping assembly 4 includes a fixed plate 401, the outer ring of the fixed plate 401 is fixed with a support 403, and the support 403 is fixed to the top of the jacking and rotating assembly 9 through a support column 402. It should be noted that the top of the jacking and rotating assembly 9 is provided with a groove adapted to the support column 402, so as to achieve a rotation adjustment angle of 120° each time the clamping and shaping assembly 3 is clamped;

[0041] A plurality of slide grooves 415 are slidably provided on the fixed disk 401, which are distributed in a circular array with the fixed disk 401 as the center, and a sliding push tooth 404 is installed in each slide groove 415, and each push tooth 404 is provided with a follower 405. A rotating disk 406 is provided on the top of the fixed disk 401, and a plurality of arc grooves 407 are distributed in a circular array with the fixed disk 401 as the center, and each arc groove 407 has three followers 405 evenly distributed along its curvature. A push rod 408 is installed on the outward end of the rotating disk 406, wherein the rotating disk 406 is rotatably provided on the inner side of the fixed disk 401, and the cover plate 410 is fixedly installed on the top of the fixed disk 401, and the rotating disk 406 is located between the fixed disk 401 and the cover plate 410;

[0043] Detailed, such as Figure 7-8 As shown, the inner support cylinder member 8 includes an inner support cylinder 801, and a handle 802 for manually grasping and disassembling is integrally formed on the top of the inner support cylinder 801. The outer ring of the inner support cylinder 801 is provided with an inner ring 803, an outer ring I804 and an outer ring II805 from bottom to top. The outer ring I804 is provided with a cross groove I806. The span between the cross groove I806 and the outer ring I804 is used to accommodate two layers of copper wires. The outer ring II805 is provided with a cross groove II807. The span between the cross groove II807 and the outer ring II805 can accommodate four layers of copper wires, which can achieve the purpose of clamping the copper wires without damaging or distorting the copper wires.

[0044] It should be noted that the number of outer rings (i.e. outer ring I804 and outer ring II805) set (n / 2-1) is set according to the number of layers n of the stator 10, and the arc range of the inner ring 803 and the outer ring distribution is evenly distributed according to the number of two-layer copper wire groups (720° / n) to ensure that the clamping and shaping work can be achieved after the stator 10 rotates one circle, and multiple protrusions 808 are provided on the inner ring 803, outer ring I804 and outer ring II805, and the number of protrusions 808 is consistent with the number of push teeth 404. During the clamping process, the copper wire pair is placed between the push teeth 404 and the protrusions 808, so that the copper wire pair is first tightly attached, and then the pneumatic clamp 304 clamps the upper end of the copper wire pair, and then the servo reduction motor 301 drives the pneumatic clamp 304 to rotate, so that the relative surfaces of the copper wire pair are further tightly attached, avoiding the problem of large and uneven solder joints caused by large cracks in the copper wire pair (the copper wire pair is Figure 9 (the number of pairs of copper wires represented by ∧ in the figure).

Then, the push teeth 404 at the corresponding positions of the inner ring 803, the outer ring I 804 and the outer ring II 805 are extended and respectively abut against the outer sides of the copper wires of the second layer, the fourth layer and the sixth layer, thereby achieving the purpose of clamping the copper wires of two adjacent layers from the inside out, in groups of two.

[0048] S3: The pneumatic clamping claws 304 at the bottom of the clamping and shaping component 3 clamp the two opposite copper wires, and then rotate at a certain angle to make the two copper wires close to each other closer. Each time a pair of copper wires is clamped, the lifting and rotating component 9 drives the stator 10 to rotate, so that the clamping and shaping component 3 faces the next pair of copper wires, and completes the clamping and shaping of the next pair of copper wires, thereby completing the clamping and shaping of the copper wire pairs of adjacent layers of copper wires at the one-to-one corresponding positions of the inner ring 803, the outer ring I 804 and the outer ring II 805;

[0049] S4: Rotate the inner support cylinder 8 and the clamping assembly 4 120 degrees at the same time;

[0050] S5. Repeat step S2 to complete the clamping of the copper wires. After completing step S2, continue to repeat the action of step S3 to achieve the clamping and shaping of the copper wire pairs of adjacent layers of copper wires in sequence.
