[0002] With the rapid development of new energy vehicles, the pace of vehicle version updates and iterations is accelerating, leading to an increase in the quantity and frequency of prototype requirements.
[0003] Slot cover paper is an important component of an electric motor, inserted into the stator slots of the stator windings to provide insulation. During motor manufacturing, the slot cover paper is often pre-processed into a predetermined shape (generally a roughly U-shaped structure) to match the stator slots, facilitating its placement. However, in the manual prototype manufacturing stage, tooling that improves the efficiency of slot cover paper stacking is scarce. Therefore, slot cover paper is typically stacked manually during prototype manufacturing. Manual stacking is not only difficult and inefficient, but also makes it difficult to ensure the consistency of the slot cover paper. Utility Model Content

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present invention are shown in the accompanying drawings.
[0029] It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0030] like Figure 1 As shown, the present invention provides a slotted paper stacking fixture, including a stacking base plate 1 and a stacking pressure plate 3. Both the stacking base plate 1 and the stacking pressure plate 3 are rectangular, and the edge of the stacking base plate 1 is flush with the edge of the stacking pressure plate 3. The thickness of the stacking base plate 1 is greater than the thickness of the stacking pressure plate 3. When the slotted paper stacking fixture is in use, the stacking pressure plate 3 is pressed tightly against the stacking base plate 1.
[0031] The stacking base plate 1 has multiple spaced-apart grooves 11. The spacing between two adjacent grooves 11 can be equal or unequal, and the axial direction of the groove 11 is consistent with the length direction or the width direction of the stacking base plate 1. Both sides of the groove 11 have stepped surfaces, and the two stepped surfaces are located on the same horizontal plane, making the groove 11 a stepped groove. The distance between the stepped surface and the upper surface of the stacking base plate 1 is greater than the thickness of the groove cover paper. At the same time, the width of the two stepped surfaces in the groove 11 is equal, that is, the central axis of the upper part of the groove 11 and the central axis of the lower part of the groove 11 are on the same vertical plane.
[0032] In this embodiment, the upper part of the pressing groove 11 refers to the portion of the pressing groove 11 above the step surface, and the lower part of the pressing groove 11 refers to the portion of the pressing groove 11 below the step surface. The width of the upper part of the pressing groove 11 is the same as the width of the groove cover paper when it is not folded, so that when the groove cover paper is not folded, the two step surfaces on both sides of the pressing groove 11 can support the groove cover paper, and the two sides of the upper part of the pressing groove 11 can limit the two sides of the groove cover paper, ensuring that the central axis of the groove cover paper and the central axis of the pressing groove 11 are on the same vertical plane, thereby minimizing the displacement of the groove cover paper during stacking and ensuring the quality of the groove cover paper after forming.
[0033] In this embodiment, the lower part of the groove 11 matches the shape of the folded cover paper. For example, if the cover paper is folded into a V-shape, then the part of the groove 11 below the step surface is V-shaped; if the cover paper is folded into a trapezoid, then the part of the groove 11 below the step surface is trapezoidal. Of course, the shape of the lower part of the groove 11 can be adjusted according to the actual situation, and is not limited to V-shape or trapezoidal.
[0034] In this embodiment, to ensure that the pressing plate 3 can press the grooved cover paper placed in the pressing groove 11 when pressed against the pressing base plate 1, the pressing base plate 1 also has a pressing strip 31 corresponding to the pressing groove 11. The maximum width of the pressing strip 31 is adapted to the maximum width of the lower part of the pressing groove 11, and the pressing part of the pressing strip 31 is adapted to the shape of the lower part of the pressing groove 11. It should be noted here that the pressing part of the pressing strip 31 is the part of the pressing strip 31 that presses the grooved cover paper to form the shape.
[0035] In this embodiment, although the maximum width of the pressure strip 31 and the maximum width of the lower part of the pressure groove 11 are adapted to each other, which will result in a certain gap between the pressure strip 31 and the upper sides of the pressure groove 11 during the stacking process of the groove cover paper, the entire groove cover paper will be pressed between the pressure groove 11 and the pressure strip 31 after being stacked by the pressure strip 31. That is, the two sides of the groove cover paper will not be left in the gap between the side wall of the pressure strip 31 and the upper sides of the pressure groove 11. Therefore, this design will not affect the stacking of the groove cover paper.
[0036] like Figure 1 , Figure 2 As shown, the slot cover paper stacking fixture in this embodiment also includes a stacking baffle 2 placed between the stacking base plate 1 and the stacking pressure plate 3, and the edge of the stacking baffle 2 is flush with the edge of the stacking base plate 1. The thickness of the stacking baffle 2 is less than the thickness of the stacking base plate 1. When the slot cover paper stacking fixture is in use, the stacking baffle 2 is pressed between the stacking pressure plate 3 and the stacking base plate 1.
[0037] The stacking baffle 2 also has a clearance notch 21 corresponding to the pressing groove 11. The width of the clearance notch 21 is adapted to the width of the lower part of the pressing groove 11, that is, the width of the clearance notch 21 is smaller than the width of the upper part of the pressing groove 11. When the folded groove cover paper is placed into the pressing groove 11, the stacking baffle 2 is placed on the stacking base plate 1. At this time, because the width of the clearance notch 21 is smaller than the width of the upper part of the pressing groove 11, the pressing strip 31 on the stacking plate 3 passes through the clearance notch 21 to gradually stack the groove cover paper in the pressing groove 11. The two sides of the groove cover paper cannot be directly lifted upward due to the restriction of the stacking baffle 2, thereby further preventing the groove cover paper from shifting during the stacking process, making the stacking of the groove cover paper more accurate and ensuring the quality of the groove cover paper.
[0038] In this embodiment, to ensure that the pressing groove 11, the clearance notch 21, and the pressing strip 31 can be quickly aligned when the pressing base plate 1, the pressing baffle 2, and the pressing plate 3 need to be pressed together, the pressing plate 3 is also provided with a positioning pin 4, and both the pressing base plate 1 and the pressing baffle 2 have positioning holes 5 that are adapted to the positioning pin 4. When the pressing base plate 1, the pressing baffle 2, and the pressing plate 3 need to press together the slotted cover paper, precise stacking can be achieved through the cooperation of the positioning pin 4 and the positioning hole 5.
[0039] In this embodiment, the positioning pin 4 can be located not only on the stacking base plate 1, but also on the stacking baffle 2 or the stacking pressure plate 3. When the positioning pin 4 is located on the stacking baffle 2, positioning holes 5 that cooperate with the positioning pin 4 are formed on the stacking base plate 1 and the stacking pressure plate 3. When the positioning pin 4 is located on the stacking pressure plate 3, positioning holes 5 that cooperate with the positioning pin 4 are formed on the stacking base plate 1 and the stacking baffle 2. That is, while ensuring that the stacking base plate 1, the stacking baffle 2, and the stacking pressure plate 3 can be accurately positioned, the positioning pin 4 can be arbitrarily fixed on one of the stacking base plate 1, the stacking baffle 2, and the stacking pressure plate 3.
[0040] In this embodiment, there can be one or more positioning pins 4. When there are multiple positioning pins 4, they are arranged symmetrically on the stacked base plate 1. The specific number of positioning pins 4 can be adjusted according to the actual situation and is not particularly limited.
[0041] In this embodiment, to keep the stacking base plate 1, stacking baffle 2, and stacking pressure plate 3 pressed together during the stacking process, bolt holes 6 are provided on the stacking base plate 1, stacking baffle 2, and stacking pressure plate 3. When it is necessary to press the stacking base plate 1, stacking baffle 2, and stacking pressure plate 3 together, locking bolts 7 are inserted into the corresponding bolt holes 6 on the stacking base plate 1, stacking baffle 2, and stacking pressure plate 3, and the locking bolts 7 are tightened with nuts 8. This makes the separation and joint locking of the stacking plates, stacking baffle 2, and stacking pressure plate 3 faster and more convenient.
[0042] To ensure the stacking effect of the groove cover paper, multiple locking bolts 7 are used to lock and fix the stacking base plate 1, stacking baffle 2, and stacking pressure plate 3 together. At least one locking bolt 7 passes through the center of the stacking base plate 1, stacking baffle 2, and stacking pressure plate 3, so that when the stacking base plate 1, stacking baffle 2, and stacking pressure plate 3 are stacked, the center of the stacking base plate 1, stacking baffle 2, and stacking pressure plate 3 will also be subjected to a clamping force, making the groove cover paper forming in the multiple pressure grooves 11 more stable and improving the stacking effect of the groove cover paper. The remaining locking bolts 7 can be arranged at intervals along the edge of the stacking base plate 1.
[0043] In this embodiment, when the stacking base plate 1, stacking baffle 2, and stacking pressure plate 3 have bolt holes 6 for the locking bolts 7 to pass through, the locking bolts 7 can also be evenly distributed on the stacking fixture, rather than necessarily having a single locking bolt 7 passing through the center of the stacking base plate 1, stacking baffle 2, and stacking pressure plate 3. That is, the arrangement of the locking bolts 7 can be adjusted arbitrarily, provided that the stacking effect of the groove cover paper is guaranteed and the processing on the stacking base plate 1, stacking baffle 2, and stacking pressure plate 3 is permissible.
[0044] In the embodiment, without considering the clamping force on the center of the stacking base plate 1, stacking baffle 2, and stacking pressure plate 3, in order to further facilitate the locking and unlocking of the stacking base plate 1, stacking baffle 2, and stacking pressure plate 3, a spring lock can be installed on the stacking base plate 1, which can lock the stacking base plate 1, stacking baffle 2, and stacking pressure plate 3 together.
[0045] In this embodiment, in order to facilitate the use of the stacking fixture and the placement of the groove cover paper, one end of the pressure groove 11 is closed, so that the groove cover paper can be directly inserted from the open end of the pressure groove 11 before stacking, making the installation and removal of the groove cover paper more convenient.
[0046] In this embodiment, in order to stack more slot cover paper at once, the pressing grooves 11 can be set into two groups. The pressing grooves 11 in the same group are arranged at intervals along the length direction of the stacking base plate 1, and the two groups of pressing grooves 11 are arranged symmetrically along the central axis of the length direction of the stacking base plate 1.
[0047] like Figure 2 , Figure 3 , Figure 4 As shown, when it is necessary to stack the groove cover paper, insert the groove cover paper into the pressure groove 11 from the open end of the pressure groove 11. Through the positioning pin 4 on the stacking pressure plate 3, stacking baffle 2 is stacked on stacking base plate 1, and stacking pressure plate 3 is stacked on stacking baffle 2. The pressure strip 31 on stacking pressure plate 3 passes through the clearance notch 21 on stacking baffle 2 and enters the pressure groove 11 to stack the groove cover paper. Insert locking bolts 7 into the bolt holes 6 that correspond to each other on stacking base plate 1, stacking baffle 2 and stacking pressure plate 3, and tighten the locking bolts 7 with nuts 8.
[0048] After the groove cover paper is stacked and formed, remove the nut 8 from the locking bolt 7, and remove the stacking plate 3 and the stacking baffle 2. Then, remove the stacked groove cover paper from the pressure groove 11.
[0049] In this embodiment, to enable the stacked cover paper to be easily removed without complete disassembly of the stacking fixture, a return spring can be fitted onto the positioning pin 4. The upper end of the return spring abuts against the stacking pressure plate 3, and the other end of the return spring abuts against the stacking baffle 2. At this time, it is necessary to ensure that the pressing part of the pressure strip 31 can press the cover paper into the pressure groove 11 when the return spring is compressed. When the cover paper needs to be placed into the pressure groove 11 or the stacked cover paper needs to be removed from the pressure groove 11, the nut 8 on the locking bolt 7 is loosened, and the return spring... The spring pushes the stacking plate 3 away from the stacking baffle 2 through its own elastic force, so that the pressure strip 31 on the stacking plate 3 gradually exits the pressure groove 11. When the stacking plate 3 completely exits the pressure groove 11, the groove cover paper to be stacked is directly inserted into the upper part of the pressure groove 11 from the open end of the pressure groove 11, or the stacked groove cover paper is pulled out of the pressure groove 11. After the groove cover paper to be stacked is placed in the upper part of the pressure groove 11, the nut 8 on the locking bolt 7 is tightened, the return spring is compressed, and the pressure strip 31 on the stacking plate 3 gradually enters the pressure groove 11 to stack the groove cover paper.
