Operation of the internal diameter measurement system is based on the scanning of the hole surface by laser rotation sensors.
The system contains the two stages measuring head with three laser sensors inside, Figure 1.
Figure 1. System structure
The first stage is intended for measurement of hole with 15...40 mm diameters and contains one laser sensor (sensor #1 on the figure 1) with measurement range of 6...21 mm from the head axis.
The second stage is intended for measurement of holes with 50...70 mm diameters and contains two laser sensors (sensors #2 and #3) with shifted and overlapped
measurement ranges, 24...31 mm and 30...37 mm from head axis.
The measuring head is mounted on the rotation module.
Radiation of a semiconductor lasers from the sensors is focused onto the object surface. Radiation reflected by the surface is collected by input lens of the sensors. Rotating laser sensors scan the inner surface of the object, and the system transmits polar coordinates of the surface (distance from the rotation axis measured by the sensors and a corresponding angle of rotation) to the PC for calculating the required geometric parameters.
Overall and mounting dimensions of the system are shown in Figure 2.
