Ensuring high quality, long life, and high reliability during tooling operation is an inevitable requirement for technological development in the equipment manufacturing industry.

[0003] To increase the slot fill rate, guide bars need to be installed during stator core winding. However, due to structural reasons, existing guide bars have insufficient winding capacity and are easily damaged by the core. Therefore, it is necessary to optimize the guide bar design to achieve a higher slot fill rate, thereby improving efficiency and reducing manufacturing costs. Summary of the Invention

[0004] The purpose of the present utility model is to solve the problems existing in the above-mentioned prior art and to provide a guide bar suitable for a high slot fill rate motor.

[0005] The specific solution of the utility model is: a guide bar suitable for a high slot fill rate motor, including a guide bar body, wherein the guide bar body is provided with edge guards on both sides of a side facing the stator core slot teeth, and the other side of the guide bar body is provided with an arc surface, a stop surface is provided between the two side edge guards, and a groove is provided in the middle of the stop surface; the thickness A of the edge guard is in the range of 0.23-0.24mm, and the spacing B between the inner side of the edge guard and the outer side surface of the slot teeth is in the range of 0.04-0.05mm.

[0006] Furthermore, the edge guard end exceeds the stator core slot teeth by a distance C, and C is in the range of 0.15-0.17 mm.

[0007] Furthermore, the guide bar is made of die steel.

[0008] Furthermore, a sink through hole is provided on the bottom surface of the groove, and the sink is used to accommodate a screw cap, and the depth of the sink is greater than the height of the screw cap.

[0009] The utility model has the following beneficial effects: by optimizing the structural design of the guide bar, a higher slot fill rate is achieved, the motor efficiency is improved, the manufacturing cost is reduced, and the application prospect is broad. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 are within the scope of protection of the present invention.

[0016] See also Figure 1-4 This embodiment is a guide bar suitable for a high slot fill rate motor, comprising a guide bar body 1. The guide bar body 1 has edge guards 2 on both sides of the side facing the slot teeth 6 of the stator core 5. The other side of the guide bar body 1 has an arc surface. A stop surface 4 is provided between the two edge guards 2, and a groove 3 is provided in the middle of the stop surface 4. The thickness A of the edge guard 2 is within the range of 0.23-0.24 mm. When the guide bar is installed on the stator core 5, the stop surface is aligned with the slot teeth 6, and the edge guard 2 is parallel to the outer side of the slot teeth 6 on the corresponding side. The spacing B between the inner side of the edge guard 2 and the outer side of the slot teeth 6 is within the range of 0.04-0.05 mm, allowing the guide bar to pass freely during the wire insertion process. The end of the edge guard 2 extends beyond the slot teeth 6 of the stator core 5 by a distance C within the range of 0.15-0.17 mm to prevent the enameled wire from contacting the core and damaging the wire after insertion. Furthermore, the guide bar is made of die steel, specifically SKD61. Furthermore, a sunken platform through hole is provided on the bottom surface of the groove 3. The sunken platform is used to accommodate a screw cap, and the depth of the sunken platform is greater than the height of the screw cap.

[0017] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
