Technical Field

[0001] This utility model relates to the field of stator winding production for new energy round wire motors, specifically a tooling for stator winding production of new energy round wire motors. Background Technology

[0002] The stator of a new energy round wire motor is a key component of the drive system of new energy vehicles. The quality of its wire insertion directly affects the motor's performance, such as power density, efficiency, and reliability. The function of the insertion fixture is to accurately and efficiently insert the round wire into the stator slots.

[0003] However, the following drawbacks exist in the traditional production process of stator winding for new energy round wire motors:

[0004] Limited spatial movement: Traditional wiring solutions often face the problem of inconvenient spatial movement during the production process, which limits the improvement of production efficiency.

[0005] Poor integration between automation and manual assembly: Traditional wiring solutions have significant shortcomings in the integration between automated production and manual assembly, which can lead to production interruptions and increase additional time and costs.

[0006] High labor input: Traditional wire embedding solutions require a significant labor force, especially when high wire embedding precision is required. This not only increases labor costs but also leads to inconsistent product quality due to human factors.

[0007] High product damage rate: Traditional winding solutions are prone to damaging the stator or round wire during operation, thus affecting the product yield.

[0008] Unstable performance and short lifespan: Traditional winding fixtures may suffer from unstable performance and a relatively short lifespan due to design or material issues. This increases maintenance costs and replacement frequency, impacting production efficiency and cost control.

[0009] Inconvenient maintenance: Traditional winding fixtures have design flaws that make maintenance complex and time-consuming. This can easily lead to extended production downtime and affect overall production efficiency.

[0010] Therefore, we propose a production tooling for stator winding of new energy round wire motors to improve the accuracy and efficiency of stator winding of round wire motors, while reducing damage to the insulation layer of the round wire, so as to meet the requirements of new energy vehicles for high performance and large-scale production of motors.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0029] Example 1: A tooling for producing stator windings for a new energy round wire motor, see [link / reference] Figure 1 Including positioning devices,

[0030] The positioning device includes a product receiving base 1, a central connecting ring 2 installed on the top of the product receiving base 1, and an upper connecting ring 3 fixed to the top of the central connecting ring 2. The product receiving base 1 is ring-shaped and is used to stably support the entire tooling. The central connecting ring 2 is used to connect and support the upper structure. The upper connecting ring 3 is connected to the central connecting ring 2 to form a stable frame structure for precise installation of the stator to be embedded.

[0031] For details, see Figure 1The upper connecting ring 3 has multiple clamp bushings 9 arranged in a ring array on its surface, and the multiple clamp bushings 9 are straight column type.

[0032] Further, see Figure 1 It also includes an upper tray 4, which is installed on the top of the upper connecting ring 3. A set of arc-shaped grooves 7 are provided on both sides of the top of the upper tray 4. There are two arc-shaped grooves 7 in each set. Multiple rectangular components are movably installed in one set of arc-shaped grooves 7 to guide the wiring during the wiring process.

[0033] It is worth noting that, see Figure 1 The rectangular component is the copper wire guide block 8, which is concave, and the wire passes through the concave copper wire guide block 8.

[0034] It is worth noting that, see Figure 1 The upper connecting ring 3 has a groove 11 on one end of its inner wall. A stator limiting buckle 5 is installed inside the groove 11. The stator limiting buckle 5 is used to fix and limit the stator during the winding process.

[0035] It is worth mentioning that, see Figure 1 A slot 10 is provided at the top edge of the upper connecting ring 3. A support block 6 is installed inside the slot 10. The top of the support block 6 extends out of the slot 10 to support and limit the cable tray.

[0036] When using a tooling for manufacturing stator windings for a new energy round wire motor:

[0037] 1. Preparation

[0038] Check whether all parts of the tooling are intact, including the wear of the winding die, the accuracy of the positioning device, the wear of the wire feeding wheel of the wire feeding mechanism, and the operating status of the power system of the pressing mechanism.

[0039] Install the stator to be embedded onto the positioning device, ensuring that the stator and the positioning block fit tightly together and that the positioning shaft is installed accurately.

[0040] 2. Embedding operation

[0041] Adjust parameters such as tension of the wire feeding mechanism, pressing force and pressing speed of the pressing mechanism according to the specifications of the round wire and the requirements of the stator slot.

[0042] Start the wire feeding and pressing mechanisms to begin the wire insertion operation. During the insertion process, the operator must closely observe the insertion to ensure that the round wire is smoothly inserted into the stator slot. If the round wire gets stuck or there are other abnormalities, the operation should be stopped immediately and adjustments made.

[0043] 3. Complete the inspection

[0044] After the wire insertion is completed, a preliminary inspection of the stator is performed to check whether the round wires are fully embedded in the stator slots and whether the arrangement is neat. Use measuring tools to check the positional accuracy of the round wires within the slots; for example, use calipers to measure the distance between the round wires and the stator slot wall, and the deviation should be within ±0.2mm. Also check for any damage to the insulation layer of the round wires.
