A cam groove 1701 is provided on the outer surface of the end, and a guide column 1702 is fixedly installed on the outer surface of the connecting rod 9 near the bottom end. The guide column 1702 is slidably installed with the inner wall of the cam groove 1701. The outer surface of the support plate 2 near the first gear 15 is rotatably installed with the second gear 16, and the second gear 16 is meshed with the first gear 15. The outer surface of the rotation center of the second gear 16 is fixedly installed with an active dial 13. The other end of the sleeve 7 passes through the outer surface of the support plate 2 and is fixedly installed with a driven groove wheel 14. The active dial 13 is meshed with the driven groove wheel 14. The outer surface of the other side of the support plate 2 is fixedly installed with a shell 11, and the outer surface of one side of the shell 11 is fixedly installed with a driving motor 12. The output end of the driving motor 12 passes through the outer surface of the shell 11 and is fixedly installed with the rotation center of the active dial 13.
[0019] The output end of the driving motor 12 drives the active dial 13 to rotate, and the active dial 13 drives the driven groove wheel 14 to rotate intermittently. The driven groove wheel 14 drives the spring expansion sleeve 6 to rotate intermittently through the sleeve 7, so that the spring expansion sleeve 6 drives the motor stator 3 to rotate intermittently. The active dial 13 drives the turntable 17 to rotate through the second gear 16 and the first gear 15.

[0020] In this embodiment, a double-axis cylinder 18 is fixedly installed on the outer surface of one side of the shell 11, and one of the telescopic ends of the double-axis cylinder 18 penetrates the outer surface of the shell 11 and is slidably installed thereon. One of the telescopic ends of the double-axis cylinder 18 penetrates the interior of the sleeve 7 and is rotatably connected to the end face of one end of the conical expansion head 5. A conical hole is provided on the inner wall of the spring expansion sleeve 6, and a conical angle matching the inner wall of the spring expansion sleeve 6 is provided on the circumferential outer surface of the conical expansion head 5, and a plurality of openings are equidistantly provided on the circumferential outer surface of the spring expansion sleeve 6.
[0021] By moving the two telescopic ends of the double-axis cylinder 18 away from the motor stator 3, the top block 25 is driven to leave the two adjacent coil windings of the motor stator 3, which is convenient for the subsequent rotation of the motor stator 3 and the cutting line. At the same time, the double-axis cylinder 18 drives the conical expansion head 5 to fully expand the spring expansion sleeve 6 to fix the motor stator 3. The device can be used to quickly fix the position of the motor stator 3.
[0022] In this embodiment, a mounting plate is fixedly installed on the outer surface of one side of the shell 11, and a first cylinder 19 is fixedly installed on the outer surface of one side of the mounting plate. The telescopic end of the first cylinder 19 passes through the outer surface of the mounting plate and a circular top plate 20 is fixedly installed. The circular top plate 20 and the motor stator 3 are arranged at the same center of the circle, and a plurality of top columns are fixedly installed at equal distances on the outer surface of the circular top plate 20 close to the motor stator 3.
[0023] When the coil cutting of the motor stator 3 is completed, the telescopic end of the first cylinder 19 drives the arc top plate 20 to move close to the motor stator 3, so that the ejector column on the arc top plate 20 ejects the coil winding group after cutting from the inside of the stator slot, which is convenient for subsequent recovery.
[0024] In this embodiment, a square tube 22 is slidably inserted into the outer surface of the support plate 2 near the bottom, and one end of the square tube 22 passes through the outer surface of the support plate 2 and is fixedly installed with a fixing rod 21, and the top of the fixing rod 21 is fixedly connected to the end of the other telescopic end of the double-axis cylinder 18, and a sliding cavity 2201 is provided inside the square tube 22, and a slider 24 is slidably installed on the inner wall of the sliding cavity 2201, and a T-shaped inclined groove 2401 is provided on the upper surface of the slider 24, and the T-shaped inclined groove 2401 is inclined. A top block 25 is slidably installed on the inner wall of the T-shaped inclined groove 2401, and a T-shaped slide rail matching the T-shaped inclined groove 2401 is provided at the bottom end of the top block 25. The square tube 22 is close to one end of the motor stator 3 Two limit grooves 2501 are symmetrically provided on the upper surface, and two limit blocks 2502 are symmetrically fixedly installed on the outer surfaces of the opposite sides of the top block 25. The two limit blocks 2502 are slidably installed with the inner walls of the two limit grooves 2501 respectively. The outer surfaces of one end of the square tube 22 and the slider 24 are against the end surface of one end of the motor stator 3. The end surface of the other end of the slider 24 is fixedly connected with a spring 23, and the other end of the spring 23 is fixedly connected to the inner wall of the square tube 22 close to the fixed rod 21. The outer surface of the support plate 2 close to the motor stator 3 is fixedly installed with an insertion rod 26. A socket 2601 is penetrated through the outer surface of the top block 25, and the insertion rod 26 is matched with the socket 2601.
[0025] When the top block 25 is not correctly inserted into the gap between two adjacent coil windings, the top block 25 is not fully ejected to the set height. When the two telescopic ends of the double-axis cylinder 18 move away from the motor stator 3, the square tube 22 is driven to move away from the motor stator 3 through the fixing rod 21. At this time, the socket 2601 on the top block 25 cannot be aligned with the insertion rod 26. The insertion rod 26 will hold up the top block 25, and the telescopic end of the double-axis cylinder 18 cannot move, so that the conical expansion head 5 cannot expand the outer surface of the spring expansion sleeve 6, and then the position of the motor stator 3 cannot be fixed. The device reminds the operator that the position of the motor stator 3 is not fully aligned and is not aligned with the end face of the square tube 22, so as to avoid the inability to completely cut the coil when the coil is sheared later, which affects the recovery of the coil.
[0026] It should be noted that when the present invention is in use, the operator manually sets the motor stator 3 of the coil to be sheared on the circumferential outer surface of the spring expansion sleeve 6, and then presses one end of the motor stator 3 against the end face of the slider 24. At the same time, the motor stator 3 is manually reciprocated to make the motor stator 3 move close to the square tube 22 and drive the slider 24 to slide along the slide cavity 2201, and gradually press against the end face of the square tube 22. When the end face of the slider 24 is flush with the end face of the square tube 22, the slider 24 drives the top block 25 to move upward through the T-shaped inclined slide groove 2401, so that the top block 25 is inserted into the gap between two adjacent coil windings. The device is convenient for orienting the orientation of the motor stator 3, so that the subsequent top column can push out the coil. When the top block 25 is not correctly inserted into the gap between the two adjacent coil windings, at this time, the top block 25 is not completely ejected to the set height. When the two telescopic ends of the double-axis cylinder 18 move away from the motor stator 3, the square tube 22 is driven to move away from the motor stator 3 through the fixing rod 21. At this time, the socket 2601 on the top block 25 cannot be aligned with the insertion rod 26. The insertion rod 26 will support the top block 25, and the telescopic end of the double-axis cylinder 18 cannot move, so that the conical expansion head 5 cannot expand the outer surface of the spring expansion sleeve 6, and then the position of the motor stator 3 cannot be fixed. The device reminds the operator that the position of the motor stator 3 is not completely aligned and is not aligned with the end face of the square tube 22, so as to avoid the subsequent shearing of the coil, and the coil cannot be completely cut off, which affects the recovery of the coil; When the ejector block 25 is fully ejected into place, the two telescopic ends of the double-axis cylinder 18 move away from the motor stator 3, driving the ejector block 25 to leave the two adjacent coil windings of the motor stator 3, which is convenient for the subsequent rotation of the motor stator 3 and the cutting line. At the same time, the double-axis cylinder 18 drives the conical expansion head 5 to fully expand the spring expansion sleeve 6 to fix the motor stator 3. This device is convenient for quickly fixing the position of the motor stator 3. The output end of the driving motor 12 drives the active dial 13 to rotate, and the active dial 13 drives the driven groove wheel 14 to rotate intermittently. The driven groove wheel 14 drives the spring expansion sleeve 6 to rotate intermittently through the sleeve 7, so that the spring expansion sleeve 6 drives the motor stator 3 to rotate intermittently. The active dial 13 drives the turntable 17 to rotate through the second gear 16 and the first gear 15. The turntable 17 drives the connecting rod 9 to reciprocate up and down intermittently through the cam groove 1701 and the guide column 1702. The connecting rod 9 drives the cutter 4 to reciprocate up and down intermittently through the T-shaped slider 8. The device can be used to continuously and automatically shear the winding coil on the motor stator 3, with high shearing efficiency. The coil and the iron core can be completely separated, ensuring the recycling effect.

It belongs to the common knowledge in this field and is only used without improvement. In addition, the present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and circuit connection in detail.
[0028] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
