Among the core components of air-conditioning compressors, aluminum wire motor rotor punchings play a vital role. Aluminum wire motor rotor punchings are key components in air-conditioning compressors, used to form the rotating part of the motor and drive the compressor to work.
[0003] The Chinese patent discloses: a rotor punching sheet, a cast aluminum rotor and a motor, with patent application number: 202220606630.3. The patent "includes: a punching sheet body; an axial hole, located in the middle of the punching sheet body, for installing a rotating shaft; a punching sheet groove, located at the edge of the punching sheet body, and arranged in a circular array around the axial hole; wherein the punching sheet groove is a sloping top and a round bottom groove with a large top and a small bottom."
[0004] Although the punching sheet can reduce the core thickness of the motor and the amount of copper used in the winding, thus reducing the cost of the motor, the punching sheet is not provided with a heat dissipation port. A large amount of heat will be generated during long-term high-load operation. If it cannot be dissipated promptly and effectively, the motor temperature will be too high, thus affecting the operating efficiency and life of the compressor. At the same time, the punching sheet is not convenient for winding the wire. The wire needs to pass through a smaller slot to enter the punching sheet slot for winding, which increases production time and cost and makes winding inconvenient. Utility Model Content

If it cannot be dissipated in a timely and effective manner, the motor temperature will be too high, thereby affecting the operating efficiency and life of the compressor. At the same time, the punching sheet is not convenient for winding the wire. The wire needs to pass through a smaller notch to enter the punching sheet slot for winding, which increases production time and cost and makes winding inconvenient.
[0006] Based on the above-mentioned purpose, the utility model provides an aluminum wire motor rotor punching sheet for an air-conditioning compressor, comprising a punching sheet body, a plurality of winding holes for winding are evenly distributed along the outer ring of the punching sheet body, an opening is provided at the end of the winding hole away from the punching sheet body, the opening is provided with a limiting arc portion for facilitating the entry of the wound wire into the winding hole, the shape of the limiting arc portion is arc-shaped, both sides of the inner wall of the end of the winding hole away from the punching sheet body close to the opening are provided with guiding arc portions for limiting the wire, the end of the winding hole close to the punching sheet body is provided with a first heat dissipation hole for dissipating the wire in the winding hole, the outer wall of the punching sheet body is evenly and equidistantly distributed with the punching sheet body as the center of the circle, and the shape of the second heat dissipation hole is arc-shaped.
[0007] Preferably, the outer wall of the punch body is evenly and equidistantly distributed with the punch body as the center.

[0011] Preferably, the overlapping riveting point is located between the second heat dissipation hole and the shaft hole.
[0012] Preferably, the keyway hole is semicircular in shape.
[0013] The beneficial effects of the utility model are as follows: the outside air can take away the heat on the punching sheet body through the first heat dissipation hole and the second heat dissipation hole. At the same time, the first heat dissipation hole is connected with the winding hole so that the air can contact the outer wall of the coil, which greatly reduces the temperature rise rate of the punching sheet body and the coil, and the heat dissipation effect is obvious. By setting the second heat dissipation hole as an arc hole, the heat dissipation hole can be made larger, and the contact area between the outside air and the punching sheet body is increased, which not only plays a role in ventilation and auxiliary heat dissipation, but also has the function of reducing the weight of the motor rotor, so as to reduce the inertia of the rotor when rotating, and is conducive to rapid heat dissipation, thereby improving the operating efficiency and life. At the same time, the limiting arc portion can guide the wire to automatically slide into the winding groove, which not only simplifies the winding process, but also greatly improves the winding efficiency. For scenarios of mass production or rapid replacement of coils, this design can significantly reduce production time and cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] like Figures 1 to 3As shown, an aluminum wire motor rotor punching sheet for an air-conditioning compressor comprises a punching sheet body 1, a plurality of winding holes 2 for winding are evenly distributed along the outer ring of the punching sheet body 1, an opening 3 is provided at one end of the winding hole 2 away from the punching sheet body 1, the opening 3 is provided with a limiting arc portion 4 for facilitating the winding wire to enter the winding hole 2, the limiting arc portion 4 is in an arc shape, both sides of the inner wall of the end of the winding hole 2 away from the punching sheet body 1 close to the opening 3 are provided with guiding arc portions 5 for limiting the wire, the end of the winding hole 2 close to the punching sheet body 1 is provided with a first heat dissipation hole 6 for dissipating the wire in the winding hole 2, the interior of the first heat dissipation hole 6 is interconnected with the interior of the winding hole 2, the outer wall of the punching sheet body 1 is evenly and evenly distributed with second heat dissipation holes 7 at equal distances with the punching sheet body 1 as the center, and the second heat dissipation holes 7 are in an arc shape;
[0023] First, pass the shaft through the shaft hole 9. The keyway hole 10 in the shaft hole 9 cooperates with the key block on the side wall of the shaft to provide an auxiliary positioning structure for the punch body 1, so that the punch body 1 is subjected to more uniform force as the shaft rotates. The limiting arc portion 4 can guide the wire to automatically slide into the winding groove, which not only simplifies the winding process, but also greatly improves the winding efficiency. For large-scale production or scenes where coils need to be replaced quickly, this design can significantly reduce production time and cost. The wire will then be wound into the winding hole 2, and the guiding arc portion 5 will gradually shrink inward so that the coil can be limited. This not only improves the uniformity of the coil winding process, but also improves the stability of the coil during use. When working, the coil will generate a large amount of The heat generated by the heat dissipation hole 6 and the second heat dissipation hole 7 are provided on the sheet body 1, so that when the sheet body 1 is working, the outside air can pass through the first heat dissipation hole 6 and the second heat dissipation hole 7 to take away the heat on the sheet body 1. At the same time, the first heat dissipation hole 6 is connected with the winding hole 2 so that its air can contact with the outer wall of the coil, which greatly reduces the temperature rise rate of the sheet body 1 and the coil, and the heat dissipation effect is obvious. By setting the second heat dissipation hole 7 as an arc hole, the heat dissipation hole can be made larger, and the contact area between the outside air and the sheet body 1 is increased, which not only plays the role of ventilation and auxiliary heat dissipation, but also has the function of reducing the weight of the motor rotor, so as to reduce the inertia of the rotor when rotating, and is conducive to rapid heat dissipation.
[0024] For further information, see Attachment Figure 1 and Figure 2 As shown, the outer wall of the punch body 1 is evenly and equidistantly distributed with the punch body 1 as the center, and the position of the rivet point 8 is between the second heat dissipation hole 7 and the shaft hole 9. The rivet points 8 enable multiple punch bodies 1 to be tightly connected together to form an integral structure. This structure not only enhances the mechanical strength so that it can withstand greater stress and vibration, but also improves the stability of the punch body 1 during use and reduces the deformation or looseness that may occur during the operation of the motor.
[0025] For further information, see Attachment Figure 1 and Figure 2 As shown, a shaft hole 9 for convenient passage of the shaft is provided in the middle portion of the punch body 1, and a keyway hole 10 for engaging with the shaft is provided on the inner wall of the shaft hole 9. There are a plurality of keyway holes 10 distributed in an array, and the shape of the keyway holes 10 is semicircular. The keyway holes 10 in the shaft hole 9 cooperate with the key blocks on the side walls of the shaft to assist in positioning the punch body 1. This ensures that the punch body is more evenly stressed when the shaft rotates, reduces vibration or displacement that may be caused by uneven stress, thereby improving the stability and reliability of the entire system, and making the punch body 1 more evenly stressed when the shaft rotates.
