Description
Technical field
The utility model is related to a kind of measurer more particularly to a kind of cruciform joint structure alignment tolerance measuring devices.
Background technology
In the significant points of Ship Structure, there are the cruciform joint knots that upper plate and lower plate vertically meet at middle connecting plate
Structure, for example, attached beam web shown in FIG. 1 101 and only shake the cruciform joint knot that about 102 support plate vertically meets at beam and face 100
Structure.In practical situations, in order to ensure that effective transmission of power, classification society rule require upper plate and the alignment of the center line of lower plate, i.e.,
The center line of upper and lower two plates is in the same plane perpendicular to middle connecting plate.But due to precision controlling in manufacturing process
Difficulty, it is difficult to ensure that center line is perfectly aligned, alignment tolerance a is one of important indicator of structure acceptance.

a1Value (refer to the attached drawing 1), be then finished into measure snap-gauge 200 be used for in-site measurement.Refer to the attached drawing 1, with 101 He of beam web
It only shakes about 102 support plate vertically to meet at for the cruciform joint structure of beam and face 100, by the two of 200 upper end of snap-gauge when measurement
A positioning side is aligned with beam web 101 and 100 surface of beam and face top jail respectively, is reused the tools such as ruler and is measured under snap-gauge 200
It holds away from the distance value a for only shaking 102 surface of support plate2, then pass through formula a+a1+t1/ 2=a2+t2/ 2, conversion obtains practical manufacture
Alignment tolerance a values, t1It is the thickness of beam web 101, t2It is the thickness for only shaking support plate 102, no matter positive and negative the wherein value of a is only
For the direction of deviation, whole result is not influenced.It is influenced since the plate thickness of each node location changes, if thinking, directly reading contraposition is public
Difference, or by a of standard2Value control in a certain range, is examined convenient for shipowner's ship and is received, then need individually to customize for each node
Special snap-gauge, snap-gauge quantity is more, and measurement cost is high.It needs to assist using survey tools such as rulers when in addition, measuring, and need to survey
It is read under amount state, two people's cooperations could be completed, more difficult for the measurement of small space.
