Description

Technical Field

[0001] The utility model relates to the technical field of precision machinery manufacturing, in particular to an object stage for a spectral confocal displacement sensor. Background Art

[0002] By emitting broadband light and focusing it onto the surface of the object being measured through an optical system, light of different wavelengths is focused at different depths. The reflected light is collected and decomposed into light of different wavelengths by a spectrometer. The spectral characteristics of the reflected light are analyzed to determine the position of the object surface, thereby achieving the measurement of object displacement, thickness and other parameters.

[0003] During the machining process of mechanical parts, it is used to perform high-precision dimensional measurement of the machined parts, such as the diameter and length of shaft parts, and the aperture and depth of box parts. By placing the parts on the stage and measuring them with the spectral confocal displacement sensor, the actual size of the parts can be quickly and accurately obtained to ensure that they meet the design requirements.

[0004] Most spectral confocal displacement sensor stages on the market now use fixed clamps to clamp objects. The components that can directly contact the object to be measured are usually designed with anti-slip patterns on their surfaces. However, for objects with complex and irregular shapes, such as objects with curved surfaces, uneven surfaces or asymmetric shapes, it is difficult for the clamps to completely fit their surfaces, resulting in unstable clamping or excessive local pressure, affecting the measurement accuracy and even damaging the object to be measured. The existing technology designs a clamping plate structure with adjustable spacing and angles. By manual or electric means, the distance and relative angle between the clamps can be easily adjusted according to the shape and size of the object to adapt to objects of different shapes. However, multi-degree-of-freedom adjustment involves movement in multiple directions, and the matching errors between the moving parts are easy to accumulate, thereby affecting the overall accuracy of the stage.
