1.2 measurement section

(1) Measuring rod

The part is made of insulating material, and the material can be selected from bakelite or alumina ceramics for contacting the object to be tested.

(2) Grating ruler

The grating ruler is a measuring feedback device for the position movement of an object by utilizing the optical principle of moire fringes. The grating scale is 'read' by detecting the number of the moire fringes, and then the displacement and the speed of the object are calculated according to the action of the driving circuit.

Structure of displacement sensor of first grating ruler

The displacement sensor of the grating ruler consists of two parts, namely a ruler grating and a grating reading head. The scale grating is generally fixed to the movable part of the machine tool, the grating reading head is mounted to the fixed part of the machine tool, and the indicating grating is mounted in the grating reading head. The structure diagram of the grating ruler displacement sensor is as follows:

grating detection of (II) grating ruler displacement sensor

The key part of the grating detection device is a grating reading head which comprises a light source, a convergent lens, an indication grating, a photoelectric element, an adjusting mechanism and the like. The grating reading head has a plurality of structural forms, and is divided into a direct receiving type reading head (or called a silicon photocell reading head, a mirror image type reading head, a beam splitter type reading head and a metal grating reflection type reading head according to the structural characteristics and the use occasions of the reading head.

Working principle of displacement sensor of grating ruler

When the lines on the indication grating and the lines on the scale grating form an angle to place the two grating rulers, the lines on the two grating rulers are inevitably crossed. Under the irradiation of a light source, the small area near the intersection point is overlapped due to the black lines, so that the shading area is minimum, the light shading effect is weakest, and the light accumulation effect enables the area to appear bright bands.

On the contrary, in the region far away from the intersection point, because the overlapping part of the opaque black lines of the two grating rulers becomes less and less, the area of the opaque region becomes larger gradually, namely the shading area becomes larger gradually, the shading effect becomes stronger, only less light can penetrate through the grating through the region, the dark band appears in the region, and therefore the moire fringes seen by people are formed.

(IV) Moire fringe

Taking the transmission grating as an example, when a small angle θ is formed between the lines on the indication grating and the lines on the scale grating, and the two grating scale facets are placed in parallel, the two grating scale facets are positioned on the almost vertical grating lines under the irradiation of the light source to form the light and dark stripes. Such fringes are called "moire fringes". Strictly speaking, the moire fringes are arranged in a direction perpendicular to the bisector of the included angle between the two grating lines. In moire, the distance between two bright or dark stripes, called the width of the moire, is denoted by W: w is ω/2 sin (θ/2) ω/θ.
