Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1-7 As shown, a ring cutting mechanism for rapid removal of stator copper wire includes a workbench 1, the workbench 1 is embedded with a cross roller bearing 3, a transmission sleeve 4 is bolted to the lower side of the cross roller bearing 3, a rotating flattening disc 6 is provided on the lower side of the transmission sleeve 4, an arc-shaped cutter baffle 9 is fixed to the lower side of the rotating flattening disc 6 by bolts, the cutter baffle 9 is coaxially arranged with the rotating flattening disc 6, and a plurality of cutters 10 are arranged in a coaxial arc array on the lower side of the cutter baffle 9, a guide cover 5 is bolted to the lower side of the workbench 1, and the transmission sleeve 4 is located inside the guide cover 5, a flange 7 is bolted to the bottom of the guide cover 5, a fixed flattening disc 8 is bolted to the flange 7, and a plurality of through holes for inserting the copper wire at the end of the iron core are opened in an annular array on the fixed flattening disc 8, and the through holes and the cutter 10 are located on the same circular line;

[0025] A fixing assembly for fixing the iron core is provided on the lower side of the workbench 1;

[0026] A driving assembly for driving the cross roller bearing 3 to rotate and a dust collection assembly for collecting dust are provided on the upper side of the workbench 1 .

[0027] During use, the staff inserts the copper wire at the end of the iron core into the through hole of the fixed cutting disc 8, and extends the copper wire at the end to the inside of the guide cover 5. Then the staff fixes the iron core through the fixing assembly so that the iron core is positioned under the fixed cutting disc 8. Subsequently, the staff controls the driving assembly to drive the cross roller bearing 3 to rotate the transmission sleeve 4, thereby driving the rotating cutting disc 6 at the bottom of the transmission sleeve 4 to rotate, so that the cutter 10 can repeatedly cut the copper wire at the end of the iron core, realizing rapid ring cutting of the copper wire at the end of the stator core, and while the cutter 10 is ring cutting the copper wire, the dust collection assembly can suck away the waste chips generated by the ring cutting, avoiding the debris from splashing and also preventing the waste chips from falling into the inside of the stator core.

[0028] Preferably, the number of cutters 10, the position of the cutters 10 on the cutter baffles 9 and the number of cutter baffles 9 can be adjusted according to the different positions of the copper wires at the ends of the stator core to meet the requirements of various stator core ring cutting operations.

[0029] In this embodiment, the driving assembly includes a follower gear 2 and a servo motor 16 arranged on the upper side of the workbench 1. The output end of the servo motor 16 is provided with a driving gear 15 that is meshed with the follower gear 2. The follower gear 2 is coaxially fixedly connected to the inner ring of the cross roller bearing 3. When in use, the staff controls the servo motor 16 to drive the driving gear 15 to rotate. Under the action of the gear meshing, the follower gear 2 rotates with the driving gear 15, and the driving gear 15 drives the cross roller bearing 3 to rotate, thereby realizing the rapid circular cutting of the copper wire by the cutter 10.

[0030] In this embodiment, the fixing assembly includes four rotary clamping cylinders 13 arranged in a circular array on the lower side of the workbench 1 by bolts, and a pressure block 14 fixed to the output end of the rotary clamping cylinder 13 by bolts. The pressure blocks 14 are all "L"-shaped, and the four rotary clamping cylinders 13 are coaxially arranged with the guide cover 5, and the rotary clamping cylinder 13 is connected to the air supply assembly located outside. The rotary clamping cylinder 13 and the air supply assembly are both existing technologies and will not be described in detail here. When in use, after the staff inserts the copper wire at the end of the iron core into the through hole, the staff controls the clamping cylinder 13 to lift the iron core upward so that the pressure block 14 lifts the iron core to ensure the stability of the iron core when it is ring-cut.

[0031] In this embodiment, the dust collection assembly includes a mounting plate 17 fixed to the upper side of the workbench 1 by bolts, a dust collection pipe 12 fixedly connected to the mounting plate 17, and a dust collection cover 18 welded to one end of the dust collection pipe 12 located in the transmission sleeve 4. A plurality of dust collection slots 601 are provided in an annular array on the rotating cutting disc 6, and a plurality of cutting slots 901 connected to the dust collection slots 601 are provided on the cutter baffle 9. The cutting slots 901 are located between two adjacent cutters 10, and the dust collection slots 601 are located between the two adjacent cutters 10. On the inside of the dust hood 18, the dust hood 18 is coaxially arranged with the rotating cutting disk 6, and the lower side of the dust hood 18 does not contact the upper side of the rotating cutting disk 6. The dust suction pipe 12 is located at one end outside the transmission sleeve 4 and is connected to a vacuum cleaner located outside. During ring cutting, the staff starts the vacuum cleaner, and the debris generated by ring cutting passes through the cutting groove 901 and the dust suction groove 601 under the action of the vacuum cleaner into the inside of the dust hood 18, and is transported to the outside through the dust suction pipe 12 to prevent the debris from splashing or falling into the inside of the iron core.

[0032] In this embodiment, a T-shaped limit block 11 is fixed to the outer side wall of the transmission sleeve 4 by bolts, and a limit groove 501 is provided on the circumferential side of the guide cover 5. The extended end of the T-shaped limit block 11 is located in the limit groove 501. When in use, the transmission sleeve 4 drives the T-shaped limit block 11 to rotate in the limit groove 501. The limit groove 501 can limit the rotation angle of the T-shaped limit block 11, thereby limiting the rotation angle of the transmission sleeve 4, preventing the transmission sleeve 4 from rotating at an excessively large angle and causing damage to the copper wire at the end of the iron core that does not need to be cut.

[0033] In this embodiment, the opposite sides of the cutter 10 are provided with stepped grooves. When in use, the stepped grooves can prevent the cutter 10 from colliding with the copper wire behind it during repeated rotation, thereby improving the reliability of the cutter 10 during circular cutting.

[0034] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
