Description

Technical Field

[0001] The utility model relates to the technical field of new energy automobile manufacturing, in particular to an insulating paper shaping tool. Background Art

[0002] The endurance and safety performance of new energy electric vehicles are very important performances, which directly determine the convenience, safety and scope of its actual use. The efficiency, life and insulation protection of the motor have a significant impact on the above-mentioned shape. Therefore, in order to improve the above-mentioned performance of the battery, the technicians in this field add insulating paper to the outside of the winding in the motor of the new energy vehicle to improve the overall efficiency of the motor, so as to provide electrical insulation protection and enhance the safety and stability of the motor. The insulating paper can prevent the windings, coils and other components inside the motor from electrical breakdown, short circuit or leakage to the outside when they come into contact with the outside world, thereby avoiding potential safety hazards. In addition, the insulating paper can also enhance the mechanical strength of the motor windings, reduce the impact of external vibrations on the windings, and further protect the safe operation of the motor. However, in actual production, the insulating paper itself is relatively soft, and when it is placed in the corresponding slot body in the motor, a large number of folding edges will be generated, some inward and some outward, stuck at the edge of the slot body. Therefore, the technicians must pause and spend a certain amount of time to shape the insulating paper to ensure that the position of the insulating paper is appropriate and the shape is up to standard, otherwise the folding edge of the insulating paper may affect the electrical performance and mechanical strength of the motor. Folding the edges inward or outward may change the gap between the winding and the magnetic pole, affecting the magnetic field distribution and electromagnetic efficiency of the motor. At the same time, folding the edges may also increase the thickness of the insulating paper, resulting in a decrease in the filling rate of the motor slot, which in turn affects the heat dissipation performance and operating efficiency of the motor, and thus affects the endurance of new energy electric vehicles.

[0018] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to further illustrate the present invention.

[0019] First, combine Figures 1 to 3 The insulating paper shaping tooling according to the embodiment of the utility model is widely used in motor manufacturing, motor maintenance and modification, etc. In this embodiment, the focus is on the manufacturing of new energy electric vehicle motors, which is used to shape several insulating papers outside the motor windings. The insulating paper is embedded in the motor stator 1 (such as Figure 1 ) of the tank body 2 (as shown) Figure 2 As shown), the ends 6 of several insulating papers (as shown Figure 3 As shown in the figure, it is longer than the tank body 2, and this is used as an example for explanation.

[0020] like Figures 1 to 3 As shown, the insulating paper shaping tool of the embodiment of the utility model comprises a telescopic rod 3, at least one shaping end 4, and an angle adjustment component 5.

[0021] Specifically, Figures 1 to 3 As shown, the end of the telescopic rod 3 is driven by the external driving end to enter or move out of the stator 1. Through the movement of the telescopic rod 3, the tooling can accurately locate the position of the insulating paper that needs to be shaped, and adjust the contact position with the insulating paper as needed to achieve precise shaping; the shaping end 4 is arranged at the end of the telescopic rod 3, and the telescopic rod 3 drives the shaping end 4 to move. The design of the shaping end 4 can ensure that the insulating paper will not be damaged during the shaping process, and at the same time, the folded edge can be effectively pushed out from the slot body 2 to reduce the generation of folded edges; the angle adjustment component 5 is arranged on the side of the shaping end 4 close to the telescopic rod 3. The angle adjustment component 5 adjusts the contact angle between the shaping end 4 and a number of insulating papers. Since the shape of the slot body 2 of the motor stator 1 and the folded edge of the insulating paper may be different, the design of the angle adjustment component 5 can flexibly adjust the angle of the shaping end 4 to adapt to different shaping requirements and ensure the uniformity and consistency of the shaping effect.

[0022] Preferably, if Figure 3 As shown, the end of the telescopic rod 3 is provided with three shaping ends 4. The three shaping ends 4 can simultaneously process the insulating paper at different positions in the slot body 2 of the motor stator 1, which just improves the shaping efficiency. More settings will increase the cost.

[0023] Preferably, the telescopic rod 3 drives the shaping end 4 to move circumferentially along the stator 1 by self-rotation. The self-rotation design of the telescopic rod 3 allows the shaping end 4 to move circumferentially along the stator 1. There is no need to move the entire shaping end 4 horizontally, so the entire circumference of the stator 1 slot body 2 can be covered, further improving the shaping efficiency and convenience.

[0024] Preferably, if Figure 2 , 3 As shown, the shaping end 4 is a cylinder, and the direction of the rotating axis of the cylinder is at a certain angle and a certain inclination angle with the circumference of the stator 1, so as to better adapt to insulating papers of different shapes and sizes, ensure that the shaping effect is more fitting and accurate, and the cylinder saves space and is convenient for entering and exiting the center of the stator 1.

[0025] Preferably, the end of the shaping end 4 away from the telescopic rod 3 is plate-shaped (not shown in the figure). The plate-shaped design increases the contact area between the shaping end 4 and the insulating paper, thereby improving the shaping effect and stability.

[0026] Preferably, if Figure 2 , 3As shown, the end of the shaping end 4 away from the telescopic rod 3 is in the shape of a hemisphere 41. The design of the hemisphere 41 allows the shaping end 4 to contact the folded edge at points, which can better adapt to various folding situations, has stronger adaptability, and provides a more uniform shaping force.

[0027] Preferably, the surface roughness of the hemisphere is greater than that of other positions of the shaping end 4. Increasing the surface roughness of the hemisphere can increase the friction between the hemisphere and the insulating paper, making the shaping process more stable and reliable. This helps prevent the insulating paper from sliding or moving during the shaping process, ensuring the accuracy of the shaping effect.

[0028] Preferably, the hemisphere is made of elastic material, which can reduce damage and stress concentration to the insulating paper during the shaping process, thereby ensuring the integrity and electrical performance of the insulating paper.

[0029] Preferably, if Figure 3 As shown, the angle adjustment component 5 includes a base 51, a driver and a bracket 52. The bracket 52 is arranged on the base 51. The driver drives the bracket 52 to move the shaping end 4. This design makes the angle adjustment component 5 more flexible and adjustable. By driving the bracket 52 to move, the angle and position of the shaping end 4 can be accurately adjusted to adapt to different shapes and sizes of insulating paper and different models of motor stators 1.

[0030] Preferably, if Figure 3 As shown, a plurality of brackets 52 are provided on the base 51, and the driver can drive the plurality of brackets 52 to merge at the central axis of the stator 1, so as to achieve better storage, facilitate entry and exit of the stator 1, and will not damage the insulating paper.

[0031] When in use, the shaping tool drives the shaping end 4 to move along the circumference of the stator 1 through the rotation of the telescopic rod 3, and uses the driver of the angle adjustment component 5 to accurately adjust the angle and position of the shaping end 4 to adapt to insulating paper of different shapes and sizes. The angle adjustment component 5 can also be stored when entering and exiting the center of the stator 1, and the shaping end is opened at the specified position. In addition, during the shaping process, the shaping effect can be monitored in real time through the control system, and relevant parameters can be adjusted as needed to ensure the shaping quality and efficiency.

[0032] Above, refer to Figures 1 to 3 The insulating paper shaping tool according to the embodiment of the utility model is described, which can solve the folding problem of the insulating paper when it is placed in the motor slot 2, and ensure that the insulating paper can be filled into the motor slot 2 smoothly and accurately. Both inward or outward folds can be effectively shaped. The tool has strong applicability, simple operation, and low cost. The shaping time is short and efficient each time. Therefore, it can reduce the assembly time of a single motor and save production costs while ensuring the electrical performance and mechanical strength of the motor.
