Description
Technical field
The invention belongs to automobile technical fields, are related to automobile suspension system more particularly to a kind of control arm ball-bowl type ball
Connector assembly.
Background technology
Shafting installation is a highly important link during shipbuilding, and installation quality will directly affect ship
Navigation performance；And in order to ensure the installation accuracy of marine shafting, in the design phase of ship, the front and back axis hole of stern tube is all set
The bore hole surplus for having counted unilateral 15-30mm is deformed for compensating caused by boat segmental manufacture and general assembly carrying, and for
Above-mentioned bore hole surplus carries out boring after determining center line of shafting in must being looked for by shafting after ship carrying.
Stern tube boring work usual way be：Identified processing is round (i.e. in practice with shafting in being looked for according to shafting
The heart is the center of circle, the circle for requiring finish size drawn on stern tube front/rear end as radius using stern pipe) it is processing foundation, to examine
Circle (radius is more than the concentric circles of processing circle) is that boring row verifies foundation.And according to《China Shipbuilding Quality Standard (CSQS)》It is required that
It needs to control its circularity and cylindricity after stern tube bore hole, i.e., according to the difference of stern shaft hole diameter, ensures circularity and cylindricity
In 0.015mm to 0.05mm etc.；To ensure Boring preciseness, the boring work for carrying out shafting is needed.
Due to being limited by boring row length, (boring row length used in ship is usually no more than 8m at present, is more than 8m just
Can not restrain the amount of deflection that its own gravity is brought and then influence Boring preciseness), current boring for shafting work, according to stern tube shaft pipe range
The difference of degree, using the primary row of taking and the two different boring methods of the row of taking twice.
For stern tube of the total length within 5m, the row's of taking bore hole is carried out using the primary row of taking method, boring row can not be moved
And realize the boring work of axis hole before and after stern tube.And with ship enlargement and structure line style optimization, Large LNG ship and
Stern tube overall length on container ship alreadys exceed 8m, needs to carry out former and later two axis holes respectively the row of taking to carry out bore hole, i.e., twice
The row's of taking method.
Bore hole is carried out using the row's of taking method twice, need to be used for multiple times processing circle and circle is examined to carry out tune-up boring row, but institute
The width of line of the processing circle and inspection circle of picture itself will be more than 0.1mm, and therefore, it is difficult to ensure that circularity and cylindricity are less than
The required precision of 0.05mm.Simultaneously the secondary row's of taking method the bore hole period it is long, during this period Ship Structure there is also some can not
The deformation of control may further increase Boring preciseness error.In actual production, the cylindricity deviation after completion is up to
0.5mm is caused and is largely done over again.
In conclusion lacking a kind of arrangement and method for construction that can effectively improve long stern pipe marine shafting bore hole at present and for should
Simple, the fast and effectively boring row method of calibration of arrangement and method for construction, thus inevitably to the installation of marine shafting and subsequent ship
Propulsive performance has an impact.
Invention content
It is an object of the invention to the deficiency in for the above-mentioned prior art, provide a kind of for long stern pipe marine shafting
