A. Application
The optical composite image level is idely used in measuring the gradients of flat surface and cylindrical surface to horizontal direction, the planeness and straightness of slideway or base of machine tool or optical mechanical instrument as well as the correctness of installing position of equipment
B. Technical data
a. each graduation value: 0.01mm/ m
b. max measuring range: 0^ 10mm/ m
c.allowance:
1mm/ within one meter 0.01mm/ m
Within full measuring range 0.02mm/ m
d. plane deviation on working surface: 0.0003mm/ m
e. each graduation value of the spirit level: 0.1mm/ m
f. working surface ( LxW) : 165× 48mm
g. net weight of the instrument: 2kgs.
C. Structure of the instrument
The composite image level mainly consists of the following parts such as microadjusting screw, nut, graduated disc, spirit level, prism, magnifying glass, lever as well as base with plain and v working surface.
D. Working Principle
The composite image level uses prism to get the air bubble images in the spirit level composite an magnified to enhance reading accnracy and uses lever and microscrew transmitting system to enhance reading sensibility. Therefore if the work piece with a gradient of 0.01mm/ m, it can be accurately read in the composite image level ( the spirit level in the composite image level mainly plays the role of indicating zero) .
E. Operating Method
Place the composite image level on the working surface of the measuring workpiece and the gradient of the measuring workpiece causes uncoincide of the two air bubble images , rotate the graduated disc till the two air bubble images coincide and reading can be got immediately .The actual gradient of the measuring workpiece can be calculated by the following formula :
Actual gradient = gradient value X fulcrum distance x disc reading .
For example : disc reading : 5 gradients : as this composite image level is foxed with its gradient value and fulcrum distance , that is gradient value : 0.01mm / m and fulcrum distance : 165mm .
So : actural gradient = 0.01/ 1000* 165mm * 5= 0.00825mm .
F. Operation Notice
a, Before use, clean away the oil dust with
gasoline and then clean with absorbent gauze.
b, Temperature change has great influence on the
instrument and therefore it must be separated with
heat source to avoid error.
c, , During measuring, rotate the graduated disc till
the two air bubble images completely coincide and
then the readings on both positive and negative
directions can be taken.
( 4) If the instrument is found with incorrect zero position, it may be adjusted; put the instrument on a stable table and rotate the graduated disc to set the two air bubble images coincide to get first reading a; then turn the instrument by 180° and put back to its original palce. Re-rotate the graduated disc to get the two air bubbles coincide to get the second reading b. So 1/ 2 ( ±  ² ) is the zero deviation of the instrument. Loosen the three supporting screws on the graduated disc and press ligntly by hand the embossed adjusting cap; rotate the disc by 1/ 2 ( ±  ² to get the zero deviation and the point line composite; at last fasten the screws.
( 5) After work, the working surface of the instrument must be cleaned and coated with acidfree, anhydrous, antirust oil and antirust paper; put it into wooden box and the store it in a clean dry place.
( 6) If the composite image level is correctly used, our factory is responsible for all the defects due to manufacture within six months from date of delivery, But the instrument must be complete outsidely and kept well.
