Abstract

The invention discloses a method for mounting and quickly detecting curved-surface segmentation member through perspective rays. Curved-surface segmentation for assembling and positioning is finished on a scaffold; the segmentation member is provided with the perspective ray in a scribing manner in a sleeve material processing stage, so that the aims of checking the segmentation torsion and a member mounting angle by eyes are fulfilled without other measurement tools. The method disclosed by the invention is simple and is convenient to use; the complicated measurement work of the conventional curved-surface segmentation manufacturing stage is simplified; the segmentation assembling efficiency and the segmentation mounting precision and quality are improved.

Description

Utilize perspective ray to carry out the method that curved surface sectional members is installed quick test

Technical field

The present invention relates to shipbuilding, particularly a kind of perspective ray that utilizes carries out the method that curved surface sectional members is installed quick test.

Background technology

In boat segmental building course, cut sth. askew segmentation and topside small fragment of a large amount of hyperbolics is the difficult point precision problem of product precision control.Because the line style of moulding bed face is larger, and moulding bed diclinic is cut.At basal plane, carry out framework installation, assembling and positioning precision is difficult to guarantee, often occurs the phenomenon of floor setting angle dislocation, affects building berth and carries precision.When the installation accuracy of this class A of geometric unitA is checked, detection method is complicated and consume the plenty of time, has greatly affected production efficiency.

Summary of the invention

The object of the invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of perspective ray that utilizes to carry out the method that curved surface sectional members is installed quick test, the method can be installed at curved section member, can quicklook the installation accuracy of a plurality of members be checked and be adjusted.

Technical solution of the present invention is as follows:

Utilize perspective ray to carry out the method that curved surface sectional members is installed quick test, its feature is: the method comprises the steps:

1. according to design, on the installation component of member to be installed (as curved surfaces such as segmentation floor, large T rows), draw the longitudinal profile that system is certain, this line, this buttock line and member to be installed are all crossing;

2. utilize plumb bob, ruler respectively the bow end face member of segmentation and stern end face member to be carried out to measurement of angle, determine orientation angle accurately;

3. the member of zone line is installed, directly by described perspective ray, carried out positive angle observation, when perspective ray is on same straight line, member installation site and angle are correct; When perspective ray is not on same straight line, judge that the member of minute intersegmental part is installed dislocation or segmentation distortion, adjust accordingly at once, make described perspective ray on same straight line.

Technique effect of the present invention is as follows:

The present invention installs the member of the zone line beyond bow end face member and stern end face member, directly by described perspective ray, carries out positive angle observation, and when perspective ray is on same straight line, member installation site and angle are correct; When perspective ray is not on same straight line, judge that the member of minute intersegmental part is installed dislocation or segmentation distortion, adjust accordingly at once, make described perspective ray on same straight line.

Compared with prior art, the present invention can realize the installation accuracy fast detecting of a plurality of members, and checks that effect is directly perceived, need not measure by instrument, improves the checking efficiency of the on-the-spot precision of segmentation, reduces the generation of accuracy error problem.

Embodiment

Below in conjunction with embodiment and accompanying drawing, the invention will be further described, but should not limit the scope of the invention with this.

Utilize perspective ray to carry out the method that curved surface sectional members is installed quick test, comprise the steps:

1. according to design, design certain longitudinal profile on member to be installed, the crossing buttock line of this longitudinal profile and member to be installed is the perspective ray placing, and when the installation component described in segmental machining, increases the setting-out of dusting of perspective ray;

2. by plumb bob, ruler, respectively the bow end face member of segmentation and stern end face member are carried out to measurement of angle, determine orientation angle accurately;

When 3. the member of minute intersegmental part of zone line is installed, directly by described perspective ray, carry out positive angle observation, when the perspective ray of associated components is in same straight line, member installation site and angle are correct; When perspective ray is not in same straight line, judge that the member of minute intersegmental part is installed dislocation or segmentation distortion, adjust accordingly at once, make described perspective ray on same straight line.

Fig. 1 places the schematic diagram of perspective ray in jacking of the present invention, as shown in the figure, in any longitudinal profile of middle increase that designs a model, the longitudinal profile and the examine member that arrange all have crossing, crossing buttock line is the perspective ray that design places, and increases the powder marking of perspective ray in segmental machining jacking data.

In block assembly process, the perspective ray of typical segmentation places position as shown in Fig. 2 Fig. 3, and Fig. 2 is that topside segmentation/small fragment perspective ray arranges schematic diagram, and Fig. 3 is that L-type segmentation perspective ray arranges schematic diagram.The segmentation fabrication phase, use traditional plumb bob method to measure member orientation angle, determine segmentation bow end member and stern end member setting angle, referring to Fig. 4.

Intermediate member is installed behind location, and reviewer is by front visual inspection, and whether the perspective ray in check sectional members is in same straight line, referring to Fig. 5.As member installation site and angle correct, positive angle is observed, perspective ray is in same straight line; If perspective ray is not in same straight line, can judge fast segmentation internals installation dislocation or segmentation distortion.

Claims

1. utilize perspective ray to carry out the method that curved surface sectional members is installed quick test, it is characterized in that: the method comprises the steps:
