Description

Technical Field

[0001] This utility model belongs to the field of hollow cup motor coil production technology, and in particular relates to an anti-jamming coil flattening power module for a hollow cup motor coil flattening device. Background Technology

[0002] In the production process of coreless motors, coil fabrication is a crucial step, encompassing multiple processes such as winding, flattening, wire end removal, and tinning. Among these, the flattening process plays a decisive role in the final performance and quality of the motor. After the enameled wire is wound on the winding die to form a hollow coil with multiple wire ends, it must be flattened into a flat shape before proceeding to subsequent processes such as wire end removal and tinning.

[0003] In the prior art, Chinese patent CN203708033U discloses a coil flattening mechanism in the manufacturing process of motor coils. This mechanism includes a clamping component for gripping a hollow coil, a flattening component for flattening the hollow coil, and a moving component that drives the clamping component to a winding mold. The driving assembly includes a gear located below the second actuating block, a rack meshing with the gear, and a cylinder for driving the rack. The operating mechanism of the driving assembly is as follows: the cylinder pushes the rack to move, causing the two gears meshing with it to rotate. The second actuating block connected to the gear rotates accordingly. Since the first actuating block is engaged with the second actuating block, the first actuating block also rotates with the gear. The first and second pressing plates are respectively connected to the first actuating block, thereby achieving a misaligned movement of the first pressing plate relative to the second pressing plate, thus flattening the hollow coil into shape.

[0004] The shortcomings of existing technologies lie in the fact that when the first and second pressing plates are driven by the existing drive components, their movement paths are entirely controlled by the drive components. In practice, due to the relatively long length of the first and second pressing plates and the lack of effective guiding structures in the vertical direction, as well as the fact that the direct power (cylinder-driven rack structure) is located on one side of the gear, the movement accuracy of the first and second pressing plates is low and their movement is not smooth. Ultimately, this leads to uneven force or even force misalignment when flattening and shaping the hollow coil, making it difficult to ensure the stability of the flattening and shaping effect, resulting in a high scrap rate.

[0005] Therefore, it is necessary to provide a new anti-jamming coil flattening power module for a hollow cup motor coil flattening device to solve the above-mentioned technical problems. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] Based on this, the present invention provides an anti-jamming coil flattening power module for a hollow cup motor coil flattening device, in order to solve the technical problem that when the existing drive assembly drives the first pressing plate and the second pressing plate to flatten and wind the hollow coil, the hollow coil is subjected to uneven force or even force deviation, making it difficult to ensure the stability of the flattening and forming effect and resulting in a high scrap rate.

[0042] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0043] The following is in conjunction with the appendix Figure 1-9 The present invention provides a further description of the anti-jamming coil flattening power module for a hollow cup motor coil flattening device.

[0044] Please refer to this carefully. Figure 1-4 This utility model discloses an anti-jamming coil flattening power module for a hollow cup motor coil flattening device, comprising: an active linkage flattening disc 1, a driven linkage flattening disc 2, and a rack 3. An active linkage flattening disc 1 is fixedly connected to a drive gear 4, and a driven linkage flattening disc 2 is fixedly connected to a driven gear 5. The toothed surfaces 31 of the rack 3 mesh with the drive gear 4 and the driven gear 5 respectively. The anti-jamming coil flattening power module for the hollow cup motor coil flattening device also includes a rotary drive 6 and a front universal sliding assembly 18. The rotary drive 6 is located below and connected to the drive gear 4. The front universal sliding assembly 18 includes a second support block 181 and a second pressure plate 182. The second support block 181 is fixed to the other side of the upper part of the wheel system mounting block 7. 81 is a rectangular frame with an opening at the top. The second pressure plate 182 is vertically mounted on the upper opening of the second support block 181. The second pressure plate 182 is a door frame. The bottom of the second support block 181 and the second pressure plate 182 together form a second rectangular receiving cavity 183. The first front and rear thread-rolling plates 20 and the second front and rear thread-rolling plates 21 are both installed through the second rectangular receiving cavity 183. The lower surface of the second pressure plate 182 is uniformly embedded with the second upper universal ball 184, and the bottom surface of the groove of the second support block 181 is uniformly embedded with the second lower universal ball 185. The upper surfaces of the first front and rear thread-rolling plates 20 and the second front and rear thread-rolling plates 21 are in contact with the second upper universal ball 184, and the lower surfaces of the first front and rear thread-rolling plates 20 and the second front and rear thread-rolling plates 21 are in contact with the second lower universal ball 185.

[0045] According to a specific embodiment of the present invention, the anti-jamming coil flattening power module for the hollow cup motor coil flattening device further includes a first front and rear wire-rolling plate 20 and a second front and rear wire-rolling plate 21 arranged opposite to each other. The upper two sides of the active linkage rolling plate 1 are rotatably connected to the first front and rear wire-rolling plate 20 and the second front and rear wire-rolling plate 21 respectively, and the upper two sides of the driven linkage rolling plate 2 slide against the inner sidewalls of the first front and rear wire-rolling plate 20 and the second front and rear wire-rolling plate 21 respectively.

[0046] In use, the rotary drive 6 rotates, causing the drive gear 4 and the drive linkage swivel plate 1 to rotate as a whole. Since the rack 3 meshes with the drive gear 4 and the driven gear 5 respectively, the driven gear 5 and the driven linkage swivel plate 2 rotate as a whole. Ultimately, the first front and rear swivel plates 20 and the second front and rear swivel plates 21 are moved in a staggered manner, flattening the wound hollow coil 100 and obtaining a flat, regular wire block.

[0047] In this embodiment, the existing linear drive power structure is abandoned, and a structure in which the rotary drive 6 first drives the drive gear 4 to rotate is adopted, thus changing the force transmission mechanism. With this drive structure, in practical applications, it can ensure that the drive gear 4 receives a coaxial driving force provided by the rotary drive 6, ensuring its smooth rotation. This avoids the first and second front and rear thread-pulling plates 20 and 21 being subjected to tilting forces from the power source, which helps to ensure the accuracy of the movement of the first and second front and rear thread-pulling plates 20 and 21. Furthermore, with the front universal sliding assembly 18, the first and second front and rear thread-pulling plates 20 and 21 can freely extend, retract, open, and close in the horizontal plane. The upper and lower surfaces of the first and second front and rear thread-pulling plates 20 and 21 are respectively limited by the second upper universal ball 184 and the second lower universal ball 185. This structure further improves the movement accuracy and smoothness of the first and second front and rear thread-pulling plates 20 and 21. Ultimately, under the combined action of the first and second front and rear twisting plates 20 and 21, the hollow coil 100 is subjected to uniform twisting force that moves in a predetermined direction, effectively preventing wire misalignment during the flattening process of the hollow coil 100, greatly improving the stability of the flattening and forming effect, and resulting in a high yield.

[0048] According to a specific embodiment of the present invention, a first opening stroke adjusting bolt 186 and a second opening stroke adjusting bolt 187 are respectively provided on both sides of the second support block 181; the first opening stroke adjusting bolt 186 is threadedly connected to one side wall of the second support block 181, and the first opening stroke adjusting bolt 186 is set facing the outer side wall of the first front and rear thread rolling plate 20; the second opening stroke adjusting bolt 187 is threadedly connected to the other side wall of the second support block 181, and the second opening stroke adjusting bolt 187 is set facing the outer side wall of the second front and rear thread rolling plate 21.

[0049] In this embodiment, the first opening stroke adjusting bolt 186, facing the end face of the first front and rear winding plates 20, provides a limit when the first front and rear winding plates 20 are opened, and the second opening stroke adjusting bolt 187, facing the end face of the second front and rear winding plates 21, provides a limit when the second front and rear winding plates 21 are opened. When the radial dimensions of the wound hollow coil 100 are different, the extension lengths of the first opening stroke adjusting bolt 186 and the second opening stroke adjusting bolt 187 can be adjusted to obtain the required limiting stroke.

[0050] According to a specific embodiment of this utility model, the anti-jamming coil flattening power module for the hollow cup motor coil flattening device further includes a rear universal sliding assembly 17. The rear universal sliding assembly 17 includes a first support block 171 and a first pressure plate 172. The first support block 171 is fixed to one side of the upper part of the wheel system mounting block 7. The first support block 171 is generally a rectangular frame with an opening at the top. The first pressure plate 172 is horizontally covered on the upper opening end of the first support block 171, and the first support block 171 and the first pressure plate 172 together... A first rectangular receiving cavity 173 is formed. The first front and rear thread-rolling plates 20 and the second front and rear thread-rolling plates 21 are both disposed through the first rectangular receiving cavity 173. The lower surface of the first pressure plate 172 is uniformly embedded with the first upper universal ball 174, and the bottom surface of the groove of the first support block 171 is uniformly embedded with the first lower universal ball 175. The upper surfaces of the first front and rear thread-rolling plates 20 and the second front and rear thread-rolling plates 21 are in contact with the first upper universal ball 174, and the lower surfaces of the first front and rear thread-rolling plates 20 and the second front and rear thread-rolling plates 21 are in contact with the first lower universal ball 175.

[0051] In this embodiment, a rear universal sliding component 17 is added to the front universal sliding component 18. The working principle of the rear universal sliding component 17 is described in the same way as the front universal sliding component 18. The combination of the front universal sliding component 18 and the rear universal sliding component 17 forms guiding and limiting structures in the front-rear directions of the first and second front and rear yarn-rolling plates 20 and the second front and rear yarn-rolling plates 21, respectively. This helps to further improve the movement accuracy and smoothness of the first and second front and rear yarn-rolling plates 20 and the second front and rear yarn-rolling plates 21, and improves the stability of the coil flattening and forming effect.

[0054] In this embodiment, the structure of the elastic clamping wheel is formed by the combination of the compression spring 82 and the rolling clamping wheel 81, which ensures that the rack 3 always slides close to the gear, thus ensuring the meshing accuracy between the gear and the rack 3.
