Description

Technical Field

[0001] The invention relates to the technical field of stator core laminations, and in particular to an automatic positioning tool for motor stator core laminations. Background Art

[0002] In the field of modern motor manufacturing, the motor stator core is one of the core components of the motor, and its manufacturing quality has a crucial impact on the performance, efficiency and reliability of the motor. As the "heart" of new energy vehicles, the motor directly determines the vehicle's power performance, cruising range and overall operating stability.

[0003] In new energy vehicles, the efficient operation of the motor is the key to ensure the good performance of the vehicle, and the stator core is the core of the motor to achieve efficient operation. The stator core is usually composed of a large number of punchings and ventilation slot plates. A tooth pressure plate and a pressure ring are stacked on the upper and lower sides of the stacked stator core. The punchings are provided with slots, and the slots need to be aligned when the stack is assembled. Therefore, the accuracy and quality of the stack are directly related to the performance of the stator core, which in turn affects the performance of the motor of the new energy vehicle.

[0004] The traditional stator core lamination assembly is done manually, and workers need to manually place each punching sheet and ventilation slot plate in a specific position, and then perform the lamination operation. This manual positioning method has many disadvantages. On the one hand, the efficiency of manual operation is low, and it is difficult to meet the needs of large-scale industrial production. Under the background of the growing demand in the current new energy vehicle market, the output of battery-driven new energy vehicles continues to rise, and the traditional manual lamination method seriously restricts the improvement of production efficiency. On the other hand, the accuracy of manual lamination assembly is difficult to guarantee. Due to individual differences among workers and fatigue caused by long-term work, the position of the lamination will deviate, which will affect the overall quality and performance of the stator core, and ultimately affect the performance of the new energy vehicle motor, reducing the vehicle's power output stability, cruising range and reliability.

[0005] In order to improve production efficiency and stacking accuracy, some companies have begun to use automated mechanical equipment to assemble motor core stacking, but these devices require workers to position the stacking, otherwise the stacking position may deviate. Although these automated mechanical equipment have improved production efficiency to a certain extent compared to full manual operation, they still require manual assistance. Considering the high requirements of new energy vehicles for motor performance and the strict standards of efficiency and accuracy for large-scale production, it is necessary to invent an automatic positioning tool for motor stator core stacking, which can automatically position the stacking when the automated mechanical equipment is stacking, thereby further improving the manufacturing quality of the motor stator core and providing more reliable and efficient power support for new energy vehicles.
