The operation of the system is based on the principle of scanning the inner and outer surfaces of the product by rotating triangulation laser sensors.
The system contains a frame (1), on which linear guides (2, 3) with a carriage (4) are installed. The rotation module (5) with rods (6, 7) is placed on the carriage. The rod 6 is placed along the axis of the rotation module, and the rod 7 is placed with a radial shift. The rods carry triangulation laser sensors (8, 9). The system also contains the calibration template (10) placed on the rotary beam (11). The front panel of the system contains: power connector (12), Ethernet connector (13), RS485 connector (14), power button (15). On the opposite panel there is a hole (17) for installing the measured part. System emergency stop button - 16.
Figure 1
The layout of the laser sensors is shown in Figure 2, where 18 is the axis of rotation of the system, the working ranges of the sensors are shown in red. The laser head 8 contains two triangulation laser sensors with a single laser beam, and the working range of this laser head is divided into two subranges - this is done to achieve the required accuracy over a wide measurement range.
Figure 2
The position of the part during scanning is shown in Figure 3, where 19 is the part being measured.
Figure 3
The system operates as follows:
The measured part is installed so that the axis of the part coincides with the axis of
rotation of the sensors. At the command of the operator, the laser sensors are rotated and
moved in the direction of the part. Sensor 8 measures the distance to the inner surface, and
sensor 9 measures the distance to the outer surface of the part synchronously with the angle
of rotation.
The range of movement and the step of the measured cross sections are set using
the software. The obtained radial coordinates of the surfaces are transferred to a computer
for calculating the required geometric parameters.
