Description

Technical Field

[0001] The utility model relates to the technical field of automobile electronic water pumps, in particular to a stator fixing tool for an automobile electronic water pump motor. Background Art

[0002] Electric vehicles have higher requirements for thermal management systems than fuel vehicles. At present, the mainstream cooling method for electric vehicles is water cooling, using coolant as the cooling medium, and the circulation of the coolant also requires a water pump. Electric vehicles use electronic water pumps.

[0003] The electronic water pump can be adjusted with variable frequency and is not controlled by the engine speed. It has a low speed during cold start, which accelerates the temperature rise and reduces energy consumption. It works at full load when a large amount of heat dissipation is required. The heater can continue to be used after the engine is turned off. The parking heater function can automatically run for a period of time after the engine is turned off to dissipate heat for the turbine.

[0004] The motor in the electronic water pump, the motor stator is the stationary part of the motor. Its components mainly include iron core, base, coil and other parts. During the manufacturing process of the motor stator, the copper wire needs to be wound in several winding slots of the stator. When winding, the stator needs to be fixed and positioned by the stator fixing mechanism so that the copper wire can be accurately wound on the stator. The motor stator is wound on the winding machine. However, the existing stator fixing mechanism does not accurately position the motor stator when rotating. Once the motor stator deviates, the copper wire wound on the motor stator will be disordered. If the disorder of the copper wire wound on the motor stator is not discovered in time, the winding equipment will be damaged, and the maintenance equipment will affect the production efficiency. At the same time, if the disorder of the copper wire wound on the motor stator is not discovered in time, it will lead to a large number of defective products. Utility Model Content

The stator support frame 200 can be fixed on the tooling platform 110 by fasteners or clamps; the sliding platform 300 is connected to the frame 100, and two sliders 310 are slidably installed on the sliding platform 300. The two sliders 310 are symmetrically arranged.

The compression spring contacts the upper half of the movable plate 400 and is used to push the push head 410 toward the stator support frame 200. The compression spring provides a stable elastic force so that the push head 410 pushes the slider 310 to clamp the stator positioning structure 101 outward, thereby maintaining the positioning and fixation of the stator on the stator support frame 200.

[0045] Reference Figure 2 and Figure 3 In a further embodiment of the utility model, the movable plate 400 is provided with a first limiting sleeve 430 for embedding one end of the compression spring, and the mounting plate 350 is provided with a second limiting sleeve 351 for embedding the other end of the compression spring, so that the first limiting sleeve 430 and the second limiting sleeve 351 are used to limit the compression spring, so that its installation state is stable. And because the limiting hole 341 limits the rotational travel of the movable plate 400, the stability of the compression spring installation can also be further improved.
