Description

Technical Field

[0001] This utility model belongs to the technical field of motor stator slot paper mounting mold, specifically relating to a motor stator slot paper mounting mold. Background Technology

[0002] The stator of a motor is the stationary part (opposite to the rotating rotor). Its core function is to generate a magnetic field to drive the rotor to rotate, thereby converting electrical energy into mechanical energy. The slot paper is the core component of the motor stator insulation system, and its main functions include: 1. Electrical insulation, isolating the winding conductors from the iron core to prevent short circuits or leakage; 2. Mechanical protection, reducing friction, vibration, and mechanical stress between the windings and the iron core; 3. Thermal management, with some slot papers possessing high-temperature resistance to aid in winding heat dissipation; 4. Moisture and dirt protection, preventing moisture, dust, or chemicals from penetrating the windings. The selection of its materials and installation process directly affect the motor's safety, efficiency, and service life. As motors develop towards higher efficiency and smaller size, the requirements for the temperature resistance, lightweight, and environmental friendliness of the slot paper are increasing, making new composite materials (such as ceramic fiber reinforced paper) a growing trend.

[0003] Currently, slot paper installation on motor stators is typically performed using a slot paper loading machine. These machines usually load the slot paper one piece at a time into each slot. During this process, a rotation mechanism is needed to rotate the motor stator; each rotation completes one slot paper insertion. The presence of this rotation mechanism complicates the machine's operating logic, making maintenance and debugging significantly more frequent.

[0004] To address the aforementioned problems, reducing the number of indexing mechanisms can significantly increase the ease of use of the paper slotting machine and effectively reduce its maintenance frequency. To achieve this goal, this invention aims to provide a paper slotting installation mold for a motor stator. Utility Model Content

[0005] The purpose of this invention is to provide a slot paper mounting mold for an electric motor stator to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0012] Preferably, the fixing plate divides the main body into an upper main body and a lower main body. The inner wall of the lower main body is provided with a number of guide rails, and correspondingly, the moving plate is provided with a number of guide rail grooves. The number of guide rails are embedded in the corresponding guide rail grooves.

[0013] Preferably, the fixing plate divides the main body into an upper main body and a lower main body. The lower main body is provided with a locking insert on its wall, and correspondingly, the movable plate is provided with an insert groove.

[0016] Preferably, the cross-section of the U-shaped hole and the cross-section of the U-shaped column are the same, and the U-shaped column can be embedded in the U-shaped hole.

[0017] The principle of this invention is as follows: A fixed plate has several positioning posts, and a movable plate has several U-shaped posts, forming U-shaped grooves between the positioning posts and the U-shaped posts. Slotted paper is installed in the U-shaped grooves. After all the slotted paper is installed in the U-shaped grooves, the motor stator is inserted from the top of the main body. Each U-shaped groove is precisely aligned with the slot of the motor stator.

Under the action of the return springs 4, the upper surface of the movable plate 3 abuts against the lower surface of the fixed plate 2. When the movable plate 3 is fully lifted by the return springs 4, i.e., when the upper surface of the movable plate 3 abuts against the lower surface of the fixed plate 2, the top of the U-shaped posts 9 is flush with the top of the positioning posts 8. When the movable plate 3 moves to its lowest point, the top of the U-shaped column 10 is flush with the top surface of the fixed plate 2. When the movable plate 3 is fully lifted by the reset spring assembly 4, a U-shaped groove 12 is formed between the U-shaped column 9 and the positioning column 8. The U-shaped groove 12 is used to place the grooved paper. To facilitate the placement of the grooved paper and prevent the movable plate 3 from moving up and down during placement, a locking insert 13 is provided on the wall of the lower main body cylinder 7. Correspondingly, an insert groove 14 is provided on the movable plate 3. When placing the grooved paper, the locking insert 13 is inserted into the insert groove 14 to fix the movable plate 3.

The motor stator is pressed down, the U-shaped column 10 moves down, and the positioning column 8 and the slotted paper surrounding the positioning column 8 enter the slot of the motor stator. After the slotted paper is installed, the motor stator with the slotted paper is removed upward from the main body cylinder 1, and the moving plate 3 is reset. During this process, the positioning column 8 is removed from the slot of the motor stator, and the slotted paper remains in the slot of the motor stator.
