DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] See also Figure 1-8 The present invention provides a technical solution: a magnetic pole core flattening device for electric motor manufacturing capable of rapid chip loading, comprising:

[0043] A fixed platform 1 is welded to the base, and a first vertical plate 2 is welded to the upper left side of the fixed platform 1;

[0044] A hydraulic cylinder 3, which is bolted to the inner wall of the first vertical plate 2, an output end of the hydraulic cylinder 3 is connected to a mounting plate 4, and the mounting plate 4 is slidably mounted on the right side surface of the first vertical plate 2;

[0045] A connecting plate 5, which is welded to the bottom end of the mounting plate 4;

[0046] The pressing plate 6 is bolted to the bottom of the connecting plate 5 .

[0047] The bottom of the pressing plate 6 is bonded with a protective block 7 made of rubber material to reduce the chance of wear.

[0048] The interior of the fixed platform 1 is provided with:

[0049] The drive motor 8 is bolted to the inside of the fixed platform 1, and the output end of the drive motor 8 is connected to the first rotating shaft 9, so that when the drive motor 8 is started, the first rotating shaft 9 can be driven to rotate to ensure the normal operation of the angle adjustment;

[0050] The first connecting gear 10 is welded and installed on the top of the first rotating shaft 9. The left side of the first connecting gear 10 is meshed and connected with the second connecting gear 11 which can make it rotate intermittently. The number of teeth of the first connecting gear 10 is half of the number of teeth of the second connecting gear 11. The second rotating shaft 12 runs through the inside of the second connecting gear 11. When the first rotating shaft 9 rotates, it can drive the first connecting gear 10 to rotate together, and the first connecting gear 10 will drive the second connecting gear 11 and the second rotating shaft 12 to rotate intermittently together.

[0051] The placing plate 13 is welded to the top of the second rotating shaft 12. The placing plate 13 is cylindrical and can be rotated intermittently with the second rotating shaft 12, so that the iron sheet placed on the placing plate 13 can be adjusted in angle, so as to better flatten the iron sheet;

[0052] The first transmission belt 14 is connected between the second rotating shaft 12 and the first rotating rod 15. The first rotating rod 15 is arranged inside the second vertical plate 16. The second vertical plate 16 is welded and connected to the upper right side of the fixed platform 1. When the second rotating shaft 12 rotates, the first rotating rod 15 can be driven to rotate by the first transmission belt 14.

[0053] The top end of the first rotating rod 15 is connected to the second rotating rod 18 through a second transmission belt 17. The bearing of the second rotating rod 18 is installed at the bottom of the storage box 20. A first neodymium magnet 19 with magnetic properties is welded and connected to the outer wall of the second rotating rod 18. The rotation of the first rotating rod 15 drives the second rotating rod 18 to rotate, thereby realizing the transmission of the device.

[0054] The storage box 20 includes:

[0055] The through slot 21 is formed in a trapezoidal shape and is provided inside the storage box 20, so that the iron sheet can fall down along the through slot 21 better, which is convenient for the unloading operation of the iron sheet and also convenient for the staff to store the iron sheet;

[0056] The baffle 22 is arranged at the bottom of the storage box 20. The baffle 22 has the same shape as the through slot 21. The through slot 21 can be blocked and opened by the baffle 22 to achieve intermittent unloading of iron sheets, reduce the workload of the staff, and improve the processing progress of the device.

[0057] The baffle 22 comprises:

[0058] The second neodymium magnet 23 is welded to the right side surface of the baffle 22. The second neodymium magnet 23 and the first neodymium magnet 19 have the same magnetic poles, which can make the connection between the second neodymium magnet 23 and the baffle 22 more firmly. When the first neodymium magnet 19 rotates to correspond to the second neodymium magnet 23, a repulsive force is generated, thereby pushing the baffle 22 away to allow the iron sheet to be unloaded. When the first neodymium magnet 19 and the second neodymium magnet 23 are offset, the repulsive force disappears;

[0059] An elastic spring 24 has one end connected to the baffle 22, and an end of the elastic spring 24 away from the baffle 22 is connected to a limit member 25. The limit member 25 is welded to the bottom of the storage box 20. The baffle 22 can be reset by the elastic spring 24, so that when the first neodymium magnet 19 and the second neodymium magnet 23 are offset and the mutual repulsion force disappears, the baffle 22 is reset and the through slot 21 continues to be blocked to ensure the continuity of the unloading work.

[0060] The elastic force of the elastic spring 24 is smaller than the magnetic force between the first neodymium magnet 19 and the second neodymium magnet 23 having a mutually repulsive force, so that the baffle 22 can move back and forth, thereby ensuring the normal self-unloading of the iron sheet, bringing convenience to the operation of the staff.

[0061] The baffle 22 also includes:

[0062] The limit block 2201 is fixed on the upper surface of the baffle 22, so that the connection between the limit block 2201 and the baffle 22 can be more firmly established, and when the baffle 22 moves, the limit block 2201 can be driven to move together;

[0063] The groove 2202 is formed in a "T" shape on the bottom inner wall of the storage box 20. The groove 2202 is slidably connected to the baffle 22 through a "T" shaped limit block 2201. When the baffle 22 moves, the limit block 2201 can slide along the groove 2202, thereby ensuring the stability of the baffle 22 when moving, and also ensuring the stability of the entire device when in use.

[0064] Working principle of this embodiment: When using the magnetic pole core flattening device for manufacturing electric motors capable of rapid chip loading, Figure 1-4As shown, first, the staff places the device at the corresponding position, then places the prepared iron sheet in the through slot 21 inside the storage box 20, and then starts the drive motor 8, which drives the first rotating shaft 9 and the first connecting gear 10 to rotate, as shown in FIG. Figure 5 As shown, since the first connecting gear 10 is an incomplete gear and the number of teeth of the first connecting gear 10 is half of the number of teeth of the second connecting gear 11, when the first connecting gear 10 rotates, it can drive the second connecting gear 11 and the second rotating shaft 12 to rotate intermittently, and a placement plate 13 is installed at the bottom of the second rotating shaft 12, so it can drive the placement plate 13 to rotate intermittently;

[0065] At the same time, the second rotating shaft 12 drives the first rotating rod 15 to rotate through the first transmission belt 14, and the first rotating rod 15 drives the second rotating rod 18 to rotate through the second transmission belt 17. Figure 8 As shown, a first neodymium magnet 19 is provided on the outer wall of the second rotating rod 18, so that the first neodymium magnet 19 rotates with the second rotating rod 18, and the first neodymium magnet 19 and the second neodymium magnet 23 on the right side surface of the baffle 22 have the same magnetic poles, so when the first neodymium magnet 19 rotates to a position corresponding to the second neodymium magnet 23, a repulsive force can be generated, thereby pushing the second neodymium magnet 23 to drive the baffle 22 to move left together, squeezing the elastic spring 24, so that the baffle 22 and the through groove 21 are separated, so that the iron sheet in the through groove 21 falls onto the placement plate 13, and when the iron sheet rotates to the bottom of the pressure plate 6 with the rotating placement plate 13, the mounting plate 4 pushed down by the hydraulic cylinder 3 will drive the connecting plate 5 and the pressure plate 6 to descend together, thereby causing the pressure plate 6 to flatten the iron sheet, and when the first neodymium magnet 19 rotates to be offset from the second neodymium magnet 23, the repulsive force disappears, so that the baffle 22 is reset, as shown in FIG. Figure 6 As shown, since a limit block 2201 is provided at the top of the baffle 22, when the baffle 22 moves horizontally, the limit block 2201 will slide along the groove 2202, so that the baffle 22 can move more smoothly, further ensuring the stability of the device when in use. Figure 7 As shown, since a rubber protective block 7 is provided at the bottom of the pressing plate 6, when the iron sheet is flattened, not only can the normal flattening work be guaranteed, but also the wear of the iron sheet can be reduced, thereby ensuring the normal processing of the iron core. The above is the working process of the entire device. The contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
