7. Structure and operating principle
Operation of the machine is based on the scanning of the item inner hole surface by
rotating point triangulation laser sensor.
The machine contains a base on which installed a table with the V-block and fixing
screw (for placing the measured spring), linear translation mechanism, controller. The linear
translation mechanism carries the rotation module on which the laser sensor installed. On
the back side of the machine there are two connectors for power and interface.
Figure 1. Front view
Figure 2. Side view
Figure 3. View from above
The machine operates as follows:
A leaf spring must be installed onto the table and fixed in the V-block by the fixing
screw. On the operator's command, a laser sensor moves into the control hole. Rotating
laser sensor scans the inner surface of a leaf spring, and the system transmits polar
coordinates of the surface (distance from the rotation axis measured by the sensor and a
corresponding angle of rotation) to the PC for calculating the required geometric
parameters. The depth of control and number of measured cross sections are defined by
the software.

8. Connection
· Connect the machine to your PC by means of two cables (Ethernet cable and
RS485 cable).
· Connect the power cable to the rotation module (this power cable is mounted on
the machine housing).
· Connect the machine to 220V AC by using the special power cable.
All cables are shipped with the machine.
9. Network setting
The machine is shipped with the following default network configuration:
· IP address: 192.168.0.3.
It is imperative to configure the network card of the PC in the following address
space: 192.168.0.Х.
10. Intended use
10.1. Preparation for use
· Check the condition of output window of laser sensor and, if necessary, wipe it
with a soft cloth.
· Rotate a laser sensor by hand and check smooth progress.
· Check the cables and power supply.
· Make sure that the network settings are correct.
· Switch on the machine.
· Run a service program.
· Perform the calibration procedure (for the first use).
When you have done all the steps listed above, you can start the measurement
procedure. How to install the springs properly, see in the next topic.
10.2. How to install a leaf spring
Depending on the spring size, there are four ways to install it on the table.
To install a leaf spring 1, it is necessary to place it on the table tight to the V-block,
and to fix it by the fixing screw (Figure 4).
To install the smaller leaf springs (# 2, 3, 4), you need to use special liners as shown
on Figures 5, 6, 7. Liners are supplied with the machine.
