Description

Technical Field

[0001] The utility model belongs to the technical field of concentricity measurement, in particular to a device for measuring the concentricity of a motor base. Background Art

[0002] Concentricity is the degree of deviation of the center of a circle and is a special form of coaxiality. When the measured element is the center of a circle, a hole on a thin workpiece, or the axis of a shaft, the measured axis can be regarded as the measured point, and their coaxiality with the reference axis is the concentricity. The motor base needs to be measured for concentricity after production and processing to ensure that the motor base can work normally.

[0003] However, when measuring the concentricity of the existing motor base, most of them use a fixed measuring mechanism, which cannot be changed according to the size of the motor. This may cause the measured data to be inaccurate, resulting in errors in the obtained concentricity. Therefore, we propose a motor base concentricity measuring device. Utility Model Content

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:
