Description
Technical field
The invention belongs to automobile technical field, is 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 its 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, axis hole before and after stern tube is all set
The bore hole surplus of monolateral 15-30mm has been counted, the deformation produced for compensating 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 looking for by shafting after ship is carried.
Stern tube boring work usual way be：Processing circle is (i.e. with shafting in practice according to determined by during shafting is looked for
The heart is the center of circle, requires finish size as the drawn circle on stern tube front/rear end of radius with stern pipe) to process foundation, to check
Circle (concentric circles of the radius more than processing circle) verifies foundation for boring row.And according to《CSQS (CSQS)》Require,
Need to control its circularity and cylindricity after stern tube bore hole, i.e., according to the difference of stern shaft hole diameter, it is ensured that circularity and cylindricity
In 0.015mm to 0.05mm；To guarantee Boring preciseness, the boring work for carrying out shafting is needed.
Due to being limited by boring row length, (the boring row length that current ship is used is usually no more than 8m, more than 8m just
Can cannot restrain amount of deflection that self gravitation brings and then affect Boring preciseness), current boring for shafting work, according to stern tube shaft pipe range
The difference of degree, using the once row's of taking boring method different with two kinds 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 once row's of taking method, boring row can not be moved
And realize the boring work of axis hole before and after stern tube.And the maximization with ship and the optimization of structure line style, Large LNG ship and
Stern tube overall length on container ship alreadys exceed 8m, needs to carry out the row of taking respectively to former and later two axis holes 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, needs are used for multiple times processing circle and check circle to carry out tune-up boring row, but institute
The width of the processing circle of picture and the round line of inspection itself will exceed 0.1mm, therefore, it is difficult to ensureing that circularity and cylindricity are less than
The required precision of 0.05mm.Simultaneously the bore hole cycle of the secondary row's of taking method 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, causes substantial amounts of doing over again.
In sum, a kind of arrangement and method for construction that can effectively improve long stern pipe marine shafting bore hole is lacked at present and for this
Simple, the fast and effectively boring row method of calibration of arrangement and method for construction, installation thus unavoidably to marine shafting and follow-up ship
Propulsive performance produces impact.
The content of the invention
Present invention aims to above-mentioned deficiency of the prior art, there is provided a kind of for long stern pipe marine shafting
Method for boring hole, it looks for 2 shaftings of neutralization to take row by 2 shaftings, and 3 kinds of methods of calibration are used during bore hole to boring row
