Abstract
Description
Technical Field
[0001] This application relates to the field of flat wire motor coil technology, specifically a flat wire motor coil torsion forming mechanism. Background Technology
[0002] In the manufacturing process of flat wire motors, the pre-shaped hairpin coils need to be inserted into the grooves arranged along the circumference of the stator. Then, the adjacent two layers of the coils at the straight ends after insertion are twisted relative to each other at a certain angle to meet the subsequent welding process of the motor. The stator has an even number of coil layers.
[0003] Currently, simple tooling is generally used for operation. Two power sources are typically used to drive the coil to twist. One power source drives the odd-numbered layers of coil to twist in one direction, while the other power source drives the adjacent even-numbered layers of coil to twist in the other direction. Due to the springback of the coil, the coil is not neatly arranged radially at the stator end after twisting, and the arrangement is relatively scattered, resulting in poor twisting effect and affecting the subsequent processes. Therefore, a flat wire motor coil twisting and forming mechanism is needed. Utility Model Content

[0011] Preferably, the side of the second limiting plate is provided with a limiting groove corresponding to the forming block.
[0012] By adopting the above technical solution, the molding block is moved into the limiting groove, thereby limiting one side of the molding block inside the limiting groove and increasing its rotation and torsion stability.
[0013] Preferably, the moving component includes a first motor and a screw. The first motor is fixedly mounted on the side of the base. The output end of the first motor extends through the interior of the slide groove and is fixedly connected to one end of the screw. The other end of the screw is provided with a bearing seat, which is fixedly connected to the inner wall of the slide groove.
[0014] By adopting the above technical solution, the screw rotates inside the bearing housing by starting the first motor.
[0015] Preferably, the moving component further includes a slider, one side of which is threadedly connected to a screw inside a groove, and the other side of which is fixedly connected to the lower surface of the forming plate.
[0016] By adopting the above technical solution, the tightness of the coil twisting is adjusted by rotating the screw to drive the slider to move the molding plate laterally.
[0017] Preferably, a guide block is fixedly connected to one side of the upper surface of the base, and a guide hole corresponding to the forming block is opened on the side of the guide block.
[0018] By adopting the above technical solution, the coil is guided by passing through the guide hole and corresponding to the forming block, thus preventing the coil position from shifting and affecting the twisting and forming of the coil.

[0028] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.
[0029] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This application provides a flat wire motor coil torsion forming mechanism, including a base 1 and a forming plate 3. A groove 101 is formed on the upper surface of the base 1. A moving component 2 for driving the forming plate 3 to move laterally is disposed inside the groove 101. A first fixing plate 301 is fixedly connected to one side of the upper surface of the forming plate 3. A first electric telescopic rod 302 is fixedly installed on the side of the first fixing plate 301. The telescopic end of the first electric telescopic rod 302 extends through to the other side of the first fixing plate 301 and is fixedly connected to a fixing block 303. A connecting plate 304 is connected to the side of the fixing block 303. A second motor 305 is fixedly connected to one side of the connecting plate 304. The output end of the second motor 305 extends through the connecting plate 304 to the other side of the connecting plate 304 and is fixedly connected to a first limiting plate 306. A forming block 307 is fixedly connected to the side of the positioning plate 306. A limiting component 4 is provided on the other side of the upper surface of the forming plate 3 to limit the coil on the surface of the forming block 307. During the twisting of the flat wire motor coil, the first electric telescopic rod 302 is activated to drive the first limiting plate 306 to approach the limiting component 4 and limit the coil on the surface of the forming block 307 to prevent the coil from being misaligned. The moving component 2 drives the forming plate 3 to move laterally to adjust the tightness of the coil during twisting, preventing the twisted coil from being loosely arranged due to springback, resulting in poor twisting effect and affecting the subsequent process, thus improving the twisting and forming effect of the flat wire motor coil. The second motor 305 is activated to drive the first limiting plate 306 to rotate, thereby driving the forming block 307 to rotate and twisting the coil on the surface of the forming block 307.
[0030] Reference Figure 1 and Figure 4 In one aspect of this embodiment, the limiting component 4 includes a second fixing plate 401. A second electric telescopic rod 402 is fixedly installed on the side of the second fixing plate 401. The telescopic end of the second electric telescopic rod 402 passes through the side of the second fixing plate 401 and is rotatably connected to a second limiting disk 403. By activating the second electric telescopic rod 402, the telescopic end of the second electric telescopic rod 402 drives the second limiting disk 403 to move towards the molding block 307 and contact it, thereby limiting the coil to the surface of the molding block 307 between the first limiting disk 306 and the second limiting disk 403.
[0031] Reference Figure 1 , Figure 3 and Figure 4 In one aspect of this embodiment, the side of the second limiting plate 403 is provided with a limiting groove 411 corresponding to the molding block 307. By moving the molding block 307 into the limiting groove 411, one side of the molding block 307 is limited inside the limiting groove 411, increasing its rotation and torsional stability.
[0032] Reference Figure 1 and Figure 4 In one aspect of this embodiment, the moving component 2 includes a first motor 201 and a screw 202. The first motor 201 is fixedly mounted on the side of the base 1. The output end of the first motor 201 extends into the interior of the slide groove 101 and is fixedly connected to one end of the screw 202. The other end of the screw 202 is provided with a bearing seat, which is fixedly connected to the inner wall of the slide groove 101. By starting the first motor 201, the screw 202 rotates inside the bearing seat under the action of the output end of the first motor 201.
[0033] Reference Figure 1 , Figure 2 and Figure 4 In one aspect of this embodiment, the moving component 2 further includes a slider 211. One side of the slider 211 is threadedly connected to the screw 202 inside the groove 101, and the other side of the slider 211 is fixedly connected to the lower surface of the molding plate 3. The slider 211 is driven by the rotation of the screw 202 to move the molding plate 3 laterally to adjust the tightness of the coil twist.
[0034] Reference Figure 1 and Figure 4 In one aspect of this embodiment, a guide block 5 is fixedly connected to one side of the upper surface of the base 1. The guide block 5 has a guide hole 501 on its side that corresponds to the forming block 307. The coil is guided by passing through the guide hole 501 and corresponding to the forming block 307, so as to prevent the coil position from shifting and affecting the twisting and forming of the coil.
[0035] All electrical devices in this plan are powered by an external power source.
[0036] Working principle: During use, the coil is guided by passing through the guide hole 501 and corresponding to the forming block 307 to prevent coil misalignment from affecting the twisting and forming of the coil. By activating the second electric telescopic rod 402, the telescopic end of the second electric telescopic rod 402 drives the second limiting plate 403 to move towards the forming block 307 and contact it, limiting the coil to the surface of the forming block 307 between the first limiting plate 306 and the second limiting plate 403. The forming block 307 moves into the limiting groove 411, so that one side of the forming block 307 is limited inside the limiting groove 411, increasing its rotation and twisting. To ensure stability, the first electric telescopic rod 302 drives the first limiting plate 306 to approach the limiting component 4, limiting the coil to the surface of the molding block 307 to prevent the coil from being misaligned. By starting the first motor 201, the screw 202 rotates inside the bearing seat under the action of the output end of the first motor 201. The rotation of the screw 202 drives the slider 211 to move the molding plate 3 laterally to adjust the tightness of the coil twisting. By starting the second motor 305, the first limiting plate 306 rotates, thereby driving the molding block 307 to rotate, twisting the coil on the surface of the molding block 307.
