Description
Technical field
The present invention relates to a kind of measurers more particularly to a kind of monoclinic phase to hand over cruciform joint structure alignment tolerance measuring device.
Background technology
The Ship Structure region of high stress often has a higher failure risk, and to typically occur in Ship Structure more for the region of high stress
Plate intersection hands over as shown in Figure 1, existing similar to bottom side tank oblique top plate 100, bottom stringers 101 and 102 3 plate monoclinic phase of inner bottom plating
Cruciform joint structure, or it is simply viewed as the structure that inclined plate and riser intersect with transverse slat.In order to avoid oblique top plate 100 and bottom stringers
101 structure dislocation in above-below direction, which generates shearing, causes structural failure, classification society rule to require three plate center lines alignment herein,
That is the plate thickness center line of three plates intersects at a point.Since precision controlling difficulty is big during shipbuilding, can not many times protect
It demonstrate,proves entirely on the center, certain control is then carried out to deviation, makes it in the reasonable scope.But horizontal departure when three plate centerings
(i.e. alignment tolerance a) can not be estimated or directly be measured and obtain value, and scene positioning and operation is caused to have larger difficulty.
Currently, shipyard is to utilize 1 when the cruciform joint structure handed over this kind of three plates monoclinic phase carries out assembly and checkout：1
Snap-gauge subsidiary is customized, using the method for control snap-gauge and structure interval, i.e., one by one for the structural model at such node
Snap-gauge model is established, with reference to figure 1,103 two positioning sides of control snap-gauge are indulged with the bottom at measured section sews with long stitches 101 and inner bottom plating
102 are close to completely, in the position that the upper end of structure can contact, directly measure snap-gauge and measure edge and 100 structure of oblique top plate
Gap width a1Actual measurement in the reasonable scope due to control alignment tolerance a passes through angular relationship a1Actual measurement=a1Design+a × sin
θ obtains gap width a1Actual measurement is in a certain range.The angle theta of oblique top plate and inner bottom plating is not to fix not when due to structure design
Become, and three plate plate thickness of different location can also change, and need to make the snap-gauge of multiple and different angles to meet the need of positioning and measurement
It wants, causes snap-gauge quantity more.Snap-gauge generally uses aluminium alloy finishing to make simultaneously, and cost of manufacture is higher.In addition, when measuring also
Distance measurement tools subsidiary need to be used, and needs to read under measuring state, while needing two people to coordinate and completing, it is right
It is more difficult in the measurement of small space.
