Description

TECHNICAL FIELD

[0001] The utility model relates to the field of stator detection fixture, more particularly to a device for detecting the outer diameter of stator. BACKGROUND

[0002] In the field of motor manufacturing, especially in the production process of large motor with outer rotor structure, the stator as one of the core components of the motor, the accurate detection of its outer diameter size plays a crucial role in product assembly accuracy, running performance and matching of subsequent processes. At present, the size detection of the stator mostly depends on special detection platform or large measuring equipment. Especially when detecting the outer diameter of the stator, the whole stator to be detected usually needs to be carried to the fixed detection equipment for detection.

[0003] However, the stator in large outer rotor motor is usually large in size and heavy in weight, and the carrying process is complex, which needs to rely on hoisting tools or mobile brackets to assist completion. Even with certain carrying assistance conditions, the overall operation is still relatively cumbersome, not only time-consuming and laborious, but also with certain safety hazards, such as quality problems caused by knocking and damage of parts during carrying. In addition, since the measuring equipment is mostly fixed structure, it cannot be moved flexibly, and if the factory production rhythm is fast, the detection step is easy to become a bottleneck, affecting the overall production efficiency.

[0004] Although there are some attempts to apply portable detection equipment in the prior art, most of them are simple in structure and cannot effectively clamp or position the stator, which is insufficient in detection stability and accuracy. At the same time, there is lack of cooperation mechanism with the stator shaft in the detection process, which cannot ensure the outer diameter detection based on the motor shaft line, so as to cause measurement deviation.

After the interval between the vertical rod part of the detection block and the fixed seat is adjusted, the stator shaft of the to-be-detected stator is placed in the arc-shaped groove of the fixed seat.
