3 Overview
The projector is an optical mechanical metering instrument. The main structure is divided into vertical projectors (the optical axis of the objective lens is perpendicular to the work
As a countertop, the structure is shown in Figure 1) and the horizontal projector (the objective optical axis is parallel to the work surface, the structure is shown in the figure)
2), its working principle is shown in Figure 3. The light beam emitted from the light source passes through the condensing mirror and becomes parallel light to illuminate the object to be measured.
Then, through the objective lens, the image is projected onto the screen, and the workpiece is subjected to contour measurement or coordinate measurement.
Figure 1 Vertical projector Figure 2 Horizontal projector
The projector's workbench is divided into a simple type (the workbench has no reading device) and a light type (the workbench's stroke is less than, etc.)
It is available in 150mm × 75mm) and heavy duty (the stroke of the table is more than 150mm × 75mm). Projector according to the screen
