Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] A transverse cutting device for the core winding of a motor comprises a machine 1, a turntable 2 is provided on the machine 1 through a rotating support structure, the turntable 2 is driven to rotate by a rotating mechanism, a plurality of through holes 3 are distributed in an array on the turntable 2 and matched with the copper wire of the winding, the through holes 3 are used for the copper wire of the core winding to pass through, the turntable 2 is provided with a limiting structure for placing the core, when the core is placed on the turntable 2, the center of the core coincides with the rotation center of the turntable 2, a bracket 26 is provided on one side of the turntable 2, and a bracket 26 is provided on the bracket 26 near the turntable 2. A connecting seat 18 is provided for sliding at one end, and the sliding direction of the connecting seat 18 is perpendicular to the rotation tangential direction of the turntable 2, that is, perpendicular to the tangential direction of the iron core. The connecting seat 18 is driven to slide by a moving mechanism, and a cutting head 28 is provided at one end of the connecting seat 18 facing the upper turntable 2. The upper end of the cutting head 28 protrudes toward the direction of the turntable 2 and is provided with a cutting tip 29. The upper end surfaces of the cutting head 28 and the cutting tip 29 are located in the same horizontal plane as the lower surface of the turntable 2. The turntable 2 is suspended for the cutting head 28 to perform cutting below the turntable 2.

[0025] The iron core is placed on the turntable 2 through the limiting structure, the wire ends of the iron core winding are set downward, and several wire ends of the iron core winding pass through several pupils and extend to the bottom of the turntable 2. The moving mechanism drives the connecting seat 18 to move toward the turntable 2, and the cutting head 28 and the cutting tip 29 are attached to the lower surface of the turntable 2 to cut the wire ends extending out of the through hole 3, thereby performing horizontal cutting. After cutting the wire ends in one direction, the iron core and the turntable 2 are rotated by the rotating mechanism, and the uncut wire ends are rotated to the cutting path of the cutting tip 29 for cutting.

[0026] The preferred technical solution is that the moving mechanism includes a driving cylinder 22, a bending driving rod 21 and a first connecting rod 20. The lower end of the connecting seat 18 is provided with a slide rail 27 along its sliding direction. The bracket 26 has a slide groove matching the slide rail 27. The slide rail 27 is embedded in the slide groove and slides. The end of the connecting seat 18 away from the turntable 2 is provided with a hinge head 19. The first connecting rod 20, the bending driving rod 21 and the driving cylinder 22 are sequentially arranged in the direction of the hinge head 19 away from the turntable 2. The bending driving rod 21 includes a second connecting rod 24. The second connecting rod 24 is bent upward toward one end of the hinge head 19 to form an inclined third connecting rod. 25. The angle between the third link 25 and the second link 24 is an obtuse angle. The other end of the second link 24 is hinged to the driving cylinder 22. The driving cylinder 22 is vertically installed on the bracket 26. The telescopic rod of the driving cylinder 22 is hinged upward to the second link 24. The connection between the second link 24 and the third link 25 is hinged at the bracket 26. The end of the third link 25 is hinged to one end of the first link 20. The other end of the first link 20 is hinged to the hinge joint 19. When no cutting is performed initially, the hinge between the first link 20 and the third link 25 is higher than the hinge between the first link 20 and the hinge joint 19, and the first link 20 is tilted.

[0027] Through this solution, the telescopic rod of the driving cylinder 22 extends upward to push the second connecting rod 24 away from the end of the hinge joint 19 to rotate upward, thereby driving the third connecting rod 25 to rotate downward at the end close to the hinge joint 19, and then pushes the connecting seat 18 toward the turntable 2 through the first connecting rod 20, so that the cutting tip 29 cuts the thread end.

[0028] The preferred technical solution is that the rotating support structure includes several mounting frames 5 arranged at intervals around the turntable 2. The turntable 2 is circular. A support roller 6 is rotatably installed on the mounting frame 5 facing the side of the turntable 2. The turntable 2 is supported on the upper ends of the several support rollers 6 and rotates in mid-air. Several limiting wheels 7 are also provided around the turntable 2. The limiting wheels 7 are horizontally arranged and rotatably installed on the machine 1. The edge of the limiting wheel 7 rests on the edge of the turntable 2 and rotates.

[0029] The preferred technical solution is that the rotating mechanism includes a pressure cover 17 located above the turntable 2, a first rotating motor 16, a lifting frame 12 and a lifting cylinder 11. The pressure cover 17 matches the iron core. The machine 1 is provided with a support frame 8, and the lifting cylinder 11 is installed on the support frame 8. The telescopic rod of the lifting cylinder 11 is set downward and fixedly connected to the lifting frame 12. The first rotating motor 16 is installed on the lifting frame 12, and the output shaft of the first rotating motor 16 is fixedly connected downward to the pressure cover 17. The pressure cover 17 corresponds to the placement position of the iron core.

[0030] The lifting cylinder 11 drives the lifting frame 12 to descend, so that the pressure cover 17 is pressed on the upper end of the iron core, so that when the first rotating motor 16 drives the pressure cover 17 to rotate, it can drive the iron core and the turntable 2 to rotate; in addition, in the process of cutting the wire end with the cutting tip 29, the cutting tip 29 will squeeze the wire end upward, thereby easily causing the winding to move upward. Through the design of this solution, when the pressure cover 17 is pressed on the upper end of the iron core, it can press the upper end of the winding, thereby preventing the winding from moving upward.

[0031] The preferred technical solution is that the lifting cylinder 11 is slidably installed on the support frame 8, two guide rails 9 are provided in parallel on the support frame 8, and a movable plate 10 is slidably installed on the two guide rails 9. The lifting cylinder 11 is installed on the movable plate 10, and a screw rod 15 parallel to the guide rail 9 is rotatably installed on the support frame 8. A wire hole that cooperates with the screw rod 15 is connected to the movable plate 10, and the screw rod 15 is driven to rotate by a second rotating motor.

[0032] When taking or placing the iron core, the pressure cover 17 , the lifting frame 12 , the first rotary motor 16 and the lifting cylinder 11 can be moved to one side to avoid obstruction.

[0033] According to a preferred technical solution, the lifting frame 12 is provided with a guide mechanism, which includes a guide rod 13 and a matching guide sleeve 14. The guide rod 13 is vertically arranged on the lifting frame 12, and the guide sleeve 14 is arranged on the support frame 8 and above the lifting frame 12. The upper end of the guide rod 13 is arranged through the guide sleeve 14.

[0034] The preferred technical solution is that the limiting structure includes several support blocks 4 arranged in a circle, and the support blocks 4 are arranged on the turntable 2. The inner walls of the support blocks 4 are arranged in an arc shape that matches the iron core. The circular area surrounded by the inner walls of the several support blocks 4 matches the iron core, and the center of the circle coincides with the rotation center of the turntable 2. A supporting block for supporting the iron core is protruded on the inner wall of the support block 4, and the iron core is placed on the several supporting blocks.

[0035] The preferred technical solution is that the machine 1 is provided with a funnel 23 located below the turntable 2. The height of the funnel 23 is lower than the height of the cutting head 28. The funnel 23 corresponds to a number of through holes 3. When cutting the thread head, the cut waste falls into the funnel 23. A waste trough is placed below the funnel 23 for collecting waste.
