principle:
The three-dimensional measuring instrument can be defined as: a detector with three directions of movement, which can be moved on three mutually perpendicular guide rails, and the detector transmits signals in contact or non-contact manner, three axes The displacement measurement system (such as the optical ruler) calculates the coordinate (x, y, z) of each point of the workpiece and the instrument for measuring various functions through a data processor or a computer.
The working principle is that the measuring system made by grating diffraction is commonly called optical ruler, and the light source is projected onto the swimming scale and the main scale through the aiming lens, and the principle of the Moire stripe light and dark signal is generated by the light wave, and the phototube is used. Receive the signal, after amplification and correction, it can be displayed, its system and output signal situation.
operating:
1. Preparation before measurement:
(a) Check if the air bearing pressure is sufficient (b) Install the workpiece
2. Probe selection and installation:
(a) Mount the appropriate probe on the Z-bearing connector (b) Check if the Z-axis will automatically slide down (otherwise the red pressure balance adjustment valve should be adjusted)
(c) Lock the appropriate position of each axis
3. Measurement operation:
(a) Turn on the processor (b) Turn on the printer switch (c) Refer to the operation manual, select the desired function (d) to measure and read the measured value.
4. Note after completion:
(a) After the Z axis is moved to the original position, lock (b) X and Y axes are moved to the center, lock (c) Turn off the power and pressure valve (d) Remove the probe (e) and perform proper maintenance
