Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figure 1-6As shown in the figure, a stator end flattening mechanism includes an assembly plate 1 and an iron core 3. The upper side of the assembly plate 1 is rotatably connected to an adjustment turntable 11 through a bearing. Inside the adjustment turntable 11, there is a fixed cover 8 fixed to the assembly plate 1 by bolts. Inside the fixed cover 8, there is a rotating seat 7 rotatably connected to the assembly plate 1 through a bearing. The upper side of the rotating seat 7 is fixed with a wire plugging plate 12 by bolts. The wire plugging plate 12 is rotatably connected to the fixed cover 8. The adjustment turntable 11, the wire plugging plate 12, the fixed cover 8, and the rotating seat 7 are all coaxially arranged. The iron core 3 is located on the upper side of the wire plugging plate 12, and the end of the iron core 3 passes through the wire plugging plate 12 and extends to the lower side of the wire plugging plate 12. There are a plurality of cutter assemblies 6 arranged in an annular array between the adjustment turntable 11 and the fixed cover 8. The plurality of cutter assemblies 6 are all fixedly connected to the upper side of the assembly plate 1. One end of the cutter assembly 6 passes through the fixed cover 8 and contacts the end of the iron core 3. The adjustment turntable 11 can push the cutter assembly 6 to move back and forth towards the iron core 3;

[0024] A driving component for driving the adjustment turntable 11 to rotate is arranged on the upper side of the assembly plate 1;

[0025] A rotating component for driving the rotating seat 7 to rotate is arranged on the lower side of the assembly plate 1.

[0026] During use, the staff inserts the end of the iron core 3 to be cut into the wire plugging plate 12, and the end copper wire of the iron core 3 inserted into the wire plugging plate 12 is located outside the circumferential side of the rotating seat 7. Then, the staff controls the driving component to drive the adjustment turntable 11 to rotate repeatedly, so that the cutter assembly 6 moves back and forth towards the iron core 3 and cuts the end of the iron core 3 repeatedly to ensure the flatness of the end of the iron core 3. At the same time, the rotating component can drive the rotating seat 7 to rotate, thereby adjusting the position of the iron core 3, so as to facilitate the staff to cut all the copper wires at the end of the iron core 3 and improve the working efficiency of the staff in cutting the end of the iron core 3.

[0027] In this embodiment, a "wavy" roller groove 111 is annularly formed on the inner side surface of the adjusting turntable 11. The number of cutter assemblies 6 is the same as that of the roller grooves 111. The cutter assembly 6 includes a base 601 fixed to the upper side surface of the assembly plate 1 by bolts, a slide rail 603 provided on the upper side surface of the base 601, a cutter seat 604 slidably connected to the slide rail 603, a cutter 605 fixed to one end of the cutter seat 604 close to the iron core 3, a connecting block 608 installed on the other end of the cutter seat 604 away from the cutter 605 by bolts, a joint 609 bolted to the other end of the connecting block 608 away from the cutter seat 604, and a roller 610 rotatably connected to the other end of the joint 609 away from the connecting block 608. A fixing block 602 is installed at one end of the base 601 close to the upper side surface and close to the iron core 3 by bolts. Two slide rods 606 are symmetrically arranged on the side surface of the connecting block 608 close to the fixing block 602. One end of the slide rod 606 close to the fixing block 602 penetrates through the fixing block 602, and a spring 607 is sleeved on the slide rod 606. Two ends of the spring 607 are respectively in contact with the opposite side surfaces of the connecting block 608 and the fixing block 602. The roller 610 is in contact with the side surface of the roller groove 111, and the roller 610 can displace along the roller groove 111 under the rotation of the adjusting turntable 11. The cutting end of the cutter 605 passes through the fixing cover 8 and is located inside the fixing cover 8. During use, the staff drives the adjusting turntable 11 to rotate through the driving assembly, so that the roller 610 moves along the roller groove 111 towards the convex part of the roller groove 111. While the roller 610 is moving, the roller 610 pushes the connecting block 608 to move along the slide rail 603 towards the iron core 3. At this time, the cutting end of the cutter 605 moves towards the copper wire at the end of the iron core 3 and cuts the copper wire at the end of the iron core 3. After that, the adjusting turntable 11 continues to rotate under the action of the driving assembly, so that the roller 610 moves along the roller groove 111 towards the adjacent roller groove 111. At the same time, under the action of the spring 607, the roller 610 moves to the concave surface of the adjacent roller groove 111. At this time, the connecting block 608 drives the cutter 605 to move reversely along the slide rail 603 and return to the initial position. Therefore, the adjusting turntable 11 always rotates in one direction under the action of the driving assembly. At the same time, with the mutual cooperation of the roller groove 111, the roller 610 and the spring 607, the copper wire at the end of the iron core 3 is repeatedly cut flat to ensure the flatness of the copper wire at the end of the iron core 3.

[0028] In this embodiment, a plurality of positioning blocks 13 are annularly arranged on the upper side of the adjusting turntable 11 by bolts. The number of the positioning blocks 13 is the same as that of the roller grooves 111, and the positioning blocks 13 are all located on one side of the roller grooves 111. A retaining block 14 is installed on the lower side of the end of the positioning block 13 close to the iron core 3 by bolts. The roller 610 contacts the opposite sides of the retaining block 14 and the roller groove 111. During use, the driving assembly drives the adjusting turntable 11 to rotate, so that the roller 610 rolls along the opposite sides of the retaining block 14 and the roller groove 111, realizing the limit of the rolling direction of the roller 610 and ensuring the reliability of the cutter 605 when cutting the copper wire at the end of the iron core 3.

[0029] In this embodiment, the driving assembly includes a mounting seat 2 arranged on the outer side of the adjusting turntable 11 and two driving motors 4 symmetrically arranged on the upper side of the assembly plate 1 by bolts. A driving gear is arranged at the output end of the driving motor 4, and a toothed ring meshing with the driving gear is arranged on the outer side of the mounting seat 2. During use, the driving motor 4 can drive the driving gear to rotate. At the same time, the driving gear drives the toothed ring to rotate, thereby realizing the rotation of the adjusting turntable 11.

[0030] In this embodiment, the rotating assembly includes a rotating motor 5 installed on the lower side of the assembly plate 1 by bolts. The lower end of the rotating seat 7 is assembled to the assembly plate 1 and extends below the assembly plate 1. A transmission wheel 9 is arranged at the lower end of the rotating seat 7. The transmission wheel 9 is coaxially arranged with the rotating seat 7, and a transmission belt 10 is arranged between the transmission wheel 9 and the output end of the rotating motor 5 for transmission. During use, the rotating motor 5 drives the transmission wheel 9 to rotate under the action of the transmission belt 10, and then drives the rotating seat 7 to rotate, thereby realizing the rotation of the iron core 3 and improving the convenience for the staff to adjust the position of the iron core 3.

[0031] In this embodiment, the fixed cover 8 and the wire plug 12 are hermetically arranged through a gasket. During use, the fixed cover 8 and the wire plug 12 are hermetically arranged to prevent debris from splashing during the cutting process. After working for a period of time, the wire plug 12 is removed to clean the debris in the fixed cover 8.
