Description

Technical Field

[0001] The utility model relates to the technical field of wind hood detection, in particular to a concentricity detection and mounting sleeve mold device. Background Art

[0002] The wind shield is an indispensable part of the electric fan, with exquisite design and practical functions. As the core protection structure of the electric fan, the wind shield mainly plays the role of protecting the user's safety and ensuring the normal operation of the fan. The wind shield is usually made of lightweight and strong materials, such as metal or plastic, which not only has good durability, but also effectively prevents the fan blades from causing harm to the user when rotating at high speed. Its design shape is usually round or square, which perfectly matches the fan blades to ensure that the air can pass through the fan smoothly to form a strong and uniform wind flow. Another important function of the wind shield is to prevent foreign objects from invading the inside of the fan, such as dust, insects, etc. After the wind shield is made, it is indeed necessary to test the concentricity. Concentricity refers to the deviation in the axial end face, radial and oblique directions, which is crucial to ensure the stable and safe operation of the fan. If the concentricity of the wind shield does not meet the standard, it will cause relative movement between the rotor and the stator, causing serious damage to the fan or even safety accidents. Therefore, evaluating and improving the concentricity of the wind shield is an important way to ensure the stability and safety of the fan operation.

[0003] In the existing wind hood concentricity detection, in order to detect wind hoods of different sizes, it is necessary to open detection holes with different spacings. After the detection holes are opened, the positions cannot be adjusted. When more specifications of wind hoods are needed, it is necessary to continue to open detection holes. Moreover, it is easy to make mistakes after opening the detection holes again, which is inconvenient for users. Utility Model Content

[0027] Working principle of this embodiment: when the concentricity of the hood 5 needs to be tested, firstly, the hood 5 is clamped on the testing mold 4, and then the hood 5 is fixed to the top of the fixing plate 6 through the testing hole 7 by bolts, and then several equidistant points are selected on the periphery of the hood 5, such as four corners, and a support frame of a micrometer or dial gauge is set at the positions corresponding to these points on the testing table 1, and the measuring head of the gauge is vertically pointed to these points of the hood 5, and then the measured values ​​at each point are read and compared. If all the values ​​are the same or close, it means that the concentricity of the hood 5 is good; if the difference is large, the position of the hood 5 needs to be adjusted;
