In left be left side here)；The opening 14 being connected to mounting hole is offered in mounting base 4, which is then located at peace
Fill the right side of seat 4.It is arranged by this, standard can be fitted into mounting hole from opening 14, the not company of will receive when installation
The interference of extension bar 11.
The course of work of lower the present embodiment is illustrated in detail below:
When measuring the levelness of installing component: adjusting the height of the second bar 7, make itself and the lower surface edge of unit under test
A little contour, push rod 8 stretches out and contradicts the point, so that the first bar 6 is turned over an angle, whether the extension end of observation push rod 8
It is still able to contradict the lower surface edge of unit under test, if it is possible to contradict, then the first bar 6 is made to turn over an angle, continue to see
The lower surface edge whether extension end for examining push rod 8 is still able to contradict unit under test illustrates to install if still being able to contradict
There is no problem for the levelness of component.
When measuring the concentricity of installing component: adjusting the height of the second bar 7, push rod 8 is enable to contradict tested portion when stretching out
Part records the distance ρ of stretching1, so that the first bar 6 is turned over an angle, push rod 8 enable to contradict unit under test when stretching out,
Record the distance ρ stretched out2, then the first bar 6 is made to turn over an angle, so that push rod 8 is contradicted unit under test when stretching out, record is stretched
Distance ρ out3If ρ1=ρ2=ρ3, i.e., there is no problem for the concentricity of unit under test.
If unit under test is eccentrically mounted and when needing to measure its center location, the direction of X-axis and Y-axis is defined, further according to ρ1、
ρ2、ρ3And the angle, θ that the opposite X-axis of corresponding first bar 6 turns over1、θ2、θ3Calculate the position in the center of circle, by the center location with
Origin compares, and whether the installation site to determine unit under test is correct.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and be implemented, do not limit the protection scope of the present invention,
