Step 3.1, detect: adjust respectively the position of conductive filament by the hand-operated wheel of three level meters, conductive filament is contacted with water trace in the tank from top to bottom and pilot lamp is lighted;
Step 3.2, zero clearing: with the respectively zero clearing of digital display grating rule of three level meters, that is, make the test value unification of the grating scale display of three level meters be adjusted into zero, refer to that namely the flatness of water is made as the zero point of coordinate figure;
Step 4.1, choose the smoothing position: second and the 3rd level meter moved to respectively the first smoothing position along described level gauge and described V-type rail to same direction;
Step 4.2, detect and obtain test value: repeating step 3.1, and read respectively the test value (H of three level meters by the grating scale display
11, H
12, H
13); At this moment, if be not subjected to ectocine, such as environment temperature, the volume of the water in the tank is unchanged, then the test value H of First level meter
11Should be zero; In other words, the purpose of First level meter is set, carries out high-precision simulation for the flatness to water exactly, and the horizontal face amount of a reference is provided, guarantee the smoothing precision of other two level meters; That is, the water in the Real-Time Monitoring tank changes impact on whole smoothing precision with the trace that prevents the water plane.
Step 4.3, test value value difference are calculated: second level meter and First level meter test value value difference HD
21=H
12-H
11, be second level meter in the first smoothing position and in the difference in height of smoothing the coordinate reference point;
The 3rd level meter and First level meter test value value difference HD
31=H
13-H
11, be the 3rd level meter in the first smoothing position and in the difference in height of smoothing the coordinate reference point;
Step 4.4, guide rail adjustment: according to value difference HD
21With value difference HD
31, adopt parallels to adjust respectively described level gauge and described V-type rail in the level of this smoothing position;
Step 4.5, again verification: repeating step 4.2, step 4.3 and step 4.4, until value difference HD
21With value difference HD
31Be zero;
Tradition frame level or desk-top electrolevel can only be adjusted verification to the simple flat surface degree, because it is the single-piece instrument, can only show reading at body, can only be to the verification of machine tool guideway single face Adjustment of displacement, but can't adjust verification to two guide rails of lathe bed are disposable.Adopt this machine tool guideway flattening method, use three level meters simultaneously machine tool guideway to be smoothed, wherein, the reference coordinates of surface level is fixed and provide separately to the First level meter, other two level meters are placed on respectively on the smoothing position of level gauge and V-type rail, to be used for the relative level degree of dynamic test guide rail, by the cooperation of three level meters, so that the smoothing precision of machine tool guideway and smoothing efficient improve greatly.
That this machine tool guideway flattening method has is simple and practical, the smoothing precision is high, the high advantage of smoothing efficient.
The utility model adopts the interior water of tank as the standard of flatness coordinate points, and the flatness of water is carried out high-precision simulation.
Should be noted that at last: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
