Background technology
Level indicator is measurer conventional in inspection work, for checking the gradient of workpiece.Level indicator accuracy is high, it is allowed to error is ± 0.01 °, and level angle can directly be measured, and additionally needs to utilize side to carry out vertical survey as work surface when measuring vertical angle, and country is without this type equipment calibration method.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of electrolevel calibrating installation, and this device can directly carry out the calibration operation of electrolevel, not only ensure that the accuracy of measurement, and has saved the outer inspection expense of company, thus reduces company cost.
For solving problem above, the concrete technical scheme of the present invention is as follows: a kind of electrolevel calibrating installation, is arranged over base at lower work surface, is provided with two support balls and is supported base between base and lower work surface；Being provided with block in the end, one end of base, electrolevel is arranged on base, and the end contact of end face and block；It is provided with scale on the surface of base；It is provided with several gauge blocks in the support ball lower end away from block；Vertical side work surface it is provided with in the end of lower work surface.
The method using calibrating installation to calibrate electrolevel, comprises the following steps:
1) erasing electrolevel surface contaminants, and electrolevel is placed on base, and movement is close on block；
2) in verification process, two support ball and are supported on base simultaneously, and after electrolevel is stable, the angle of electrolevel is 0 °；
3) on work surface, take several the most different gauge blocks respectively, it is known that gauge block height, by combination different size gauge block structure triangle length of short sides h, obtain hypotenuse length of side L by the scale of susceptor surface, α=argsin(h/L can be tried to achieve)；
4) will calculate the α value of gained and the show value contrast of electrolevel, its difference is error amount, and the error amount of all angles test of many times takes the AME of each angle；
