What Is a Measuring Instrument?
A measuring instrument is used to measure the eccentricity of rotating objects, such as rollers and motor shafts. Eccentricity is a measure of the distance between the center of rotation and the rigid center, which is the center point of the shape of the rotating object. In rotating parts of precision instruments, eccentricity is often designed to be zero, and any deviation from eccentricity will cause malfunctions. There are two typical types of return measurement methods: transmission type, which measures by transmitted light, and reflection type, which measures by reflected light.
Uses of Measuring Instruments
Measuring instruments are used for inspection and maintenance of equipment used with rotating motors such as machine tools, robot arms, and rollers. When selecting measuring instruments, it is necessary to consider the measurement method, measurement accuracy, and measurement range.
The following is an example of the use of measuring instruments:
- Eccentricity measurement of the roller section of a rolling mill
- Eccentricity measurement of the shaft of a lathe of a machine tool
- Eccentricity measurement of a wafer rotating part of semiconductor manufacturing equipment
Principle of Measuring Instruments
The principle of eccentricity measurement is divided into transmission type and reflection type.
- Transmission Type
The transmission type measuring instruments consists of a light emitting part with a light emitting element and a light receiving part with a light receiving element. The rotating body to be measured is placed between the light emitter and the light receiver. The light emitted from the light emitter is intercepted by the rotating object, partially transmitted, and received by the photodetector. By sampling the light received by the light receiving element at high speed, the degree of runout is observed and the eccentricity is calculated. Depending on the product, some devices can accurately measure eccentricity by measuring eccentricity at multiple points. - Reflective Type
Reflective measuring instruments consist of a light-receiving element and a light-emitting element. During measurement, a laser-like light emitted by the light emitter is shone on the rotating object, and the reflected light is received to measure the eccentricity based on the deviation of the light period. Compared to the transmission type, it features of small size and the ability to measure from only one direction. However, if the object to be measured is thin, the error may be large, so care must be taken.
