Description

Technical Field

[0001] This utility model relates to the field of flat wire motor technology, and more specifically, to a flat wire motor coil torsion forming mechanism. Background Technology

[0002] Flat wire motors, due to their flat structure, can achieve a significant increase in the motor slot fill factor, thereby increasing the power density of the motor. Furthermore, the failure rate of flat wire motors can also be reduced. During the production process of flat wire motors, a twisting device is required to twist the flat copper wire.

[0003] Traditional flat wire motor coil torsion forming mechanisms use a fixed structure to fix the motor, and then use upper and lower torsion structures to torsion the flat copper wire coil. However, traditional flat wire motor torsion forming mechanisms are generally split designs, with the upper torsion mechanism and the lower support mechanism operating independently. During the torsion process, they are easily affected by factors such as mechanical vibration, resulting in inconsistent torsion angles between the upper and lower parts of the coil. This leads to uneven coil ends, which seriously affects the quality of subsequent welding processes.

[0004] Therefore, we have made improvements to this by proposing a flat wire motor coil torsion forming mechanism. Utility Model Content

[0026] Example 1 Please refer to Figure 1-4A flat wire motor coil torsion forming mechanism includes a base plate 1, with shock-absorbing feet 2 at each of the four corners of the bottom of the base plate 1, clamping components 3 on both sides of the top of the base plate 1, support columns 4 fixedly installed at each of the four corners of the top of the base plate 1, a top plate 5 fixedly installed between the four support columns 4, and a mounting frame 6 fixedly installed between the base plate 1 and the top plate 5. A torsion assembly 7 is provided in the inner cavity of the mounting frame 6. The torsion assembly 7 includes a drive motor 701, which is located on one side of the mounting frame 6. The drive end of the drive motor 701 extends through the inner cavity of the mounting frame 6 and is fixedly connected to a bevel gear 702. Both sides of the bevel gear 702 are meshed with gear rods 703. A first connecting block 704 is movably connected to the surface of the gear rod 703. Both sides of the first connecting block 704 are fixedly connected to the inner cavity of the top plate 5. A second connecting rod 705 is fixedly connected to the inner cavity of the gear rod 703. Both ends of the second connecting rod 705 are movably connected to the inner cavity of the mounting frame 6. One end of the gear rod 703 is provided with... A first synchronous pulley 706 is provided, and a synchronous belt 707 is sleeved inside the cavity of the first synchronous pulley 706. A second synchronous pulley 708 is sleeved inside the cavity of the synchronous belt 707. A connecting post 709 is fixedly connected to the cavity of the lower second synchronous pulley 708. The connecting post 709 is movably connected to the top of the base plate 1. A lower torsion plate 710 is fixedly installed on the top of the connecting post 709. The upper second synchronous pulley 708 is movably connected to the cavity of the top plate 5. A movable post 711 is slidably connected to the cavity of the upper second synchronous pulley 708. An upper torsion plate 712 is fixedly connected to the bottom of the movable post 711. A connecting plate 713 is movably connected to the top of the movable post 711. Threaded rods 714 are threadedly connected to both sides of the connecting plate 713. The bottom of the threaded rods 714 is movably connected to the top of the top plate 5. A second adjusting knob 715 is fixedly installed on the top of the threaded rods 714. Multiple torsion blocks 716 are provided in the cavity of the lower torsion plate 710. The inner cavity of the upper torsion disc 712 is provided with two extrusion blocks 717.

[0027] In the implementation process, the operator first rotates the second adjustment knob 715 to rotate the threaded rod 714. Since the threaded rod 714 is threadedly connected to the connecting plate 713, the rotation of the threaded rod 714 will drive the connecting plate 713 to move up and down, thereby driving the upper torsion disc 712 to move up and down through the movable column 711, ensuring that the upper torsion disc 712 can accurately act on the corresponding position of the coil. Then, the drive motor 701 is started, and its drive end drives the bevel gear 702 to rotate. The bevel gear 702 meshes with the racks 703 on both sides, thereby driving the two racks 703 to drive the second connecting rod 705 to rotate synchronously in the inner cavity of the mounting bracket 6. The first connecting block 704 provides support for the rotation of the racks 703. At the same time, the first synchronous pulley 706 at one end of the rack 703 rotates together, driven by the synchronous belt 707. Under the action of the first synchronous wheel 706, the second synchronous wheel 708 is driven to rotate. When the second synchronous wheel 708 rotates, the connecting column 709 fixedly connected to it will drive the lower torsion disk 710 to rotate. Multiple torsion blocks 716 in the inner cavity of the lower torsion disk 710 contact the lower part of the coil and apply torsion force to the lower part of the coil. At the same time, the second synchronous wheel 708 rotates. Since it is slidably connected to the movable column 711, the movable column 711 will rotate with it, thereby driving the upper torsion disk 712 to rotate. The two pressing blocks 717 in the inner cavity of the upper torsion disk 712 contact the upper part of the coil and work with the lower torsion disk 710 to apply torsion force to the upper part of the coil. Through the synchronous rotation of the upper torsion disk 712 and the lower torsion disk 710, torsion force is applied to the upper and lower parts of the coil at the same time, realizing the torsion forming operation of the flat wire motor coil.

[0028] Example 2 The clamping assembly 3 includes a support block 301, which is fixedly mounted on the top of the base plate 1. A clamping block 302 is slidably connected to the top of the support block 301. A first adjusting knob 303 is provided on one side of the clamping block 302. One side of the first adjusting knob 303 extends through the inner cavity of the clamping block 302 and is fixedly connected to a worm gear 304. One end of the worm gear 304 is movably connected to a support plate 305, which is fixedly connected to the inner cavity of the clamping block 302. Worm wheels 306 mesh on both sides of the worm gear 304. A first connecting rod 307 is fixedly connected to the inner cavity of the worm wheel 306. Both ends of the first connecting rod 307 are movably connected to the inner cavity of the clamping block 302. A gear 308 is fixedly connected to the bottom of the surface of the first connecting rod 307. Multiple toothed grooves 309 that mate with the gears 308 are provided on the inner side of the support block 301.

[0029] In the process, the flat wire motor coil to be processed is placed in the lower torsion plate 710 and supported by multiple torsion blocks 716. Then, the operator rotates the first adjustment knob 303, which drives the worm 304 to rotate under the support of the support plate 305. Since the worm 304 meshes with the worm wheels 306 on both sides, the rotation of the worm 304 will drive the worm wheels 306 to rotate, thereby causing the first connecting rod 307, which is fixedly connected to the worm wheels 306, to rotate synchronously. The gear 308 on the bottom surface of the first connecting rod 307 will rotate together. The gear 308 engages with the tooth groove 309 on the inner side of the support block 301. When the gear 308 rotates, the clamping block 302 will slide along the top of the support block 301. By adjusting the clamping blocks 302 of the two clamping components 3 to move closer to each other, the coil is firmly clamped in the middle, preventing displacement during the torsion process and providing a stable foundation for subsequent torsion operations.
