Abstract
The utility model discloses a kind of new boring row calibration tool and method of calibration, including L-type fixed block and installed in the upper conical stud of fixed block, described screw thread of the fixed block provided with screwed hole and taper stud matches；Simultaneously for produce reality, new school row's instrument is arranged on stern pipe front/rear end using the mode of welding, spot welding behind stud position is adjusted and fixes.Its school row's accuracy can be accurate to 0.02mm, it can be ensured that stern tube boring precision.The utility model is manufactured and material cost is relatively low, the boring row checking precision during boring for shafting is improved, the need for meeting subsequent production.
Description
Technical field
The utility model is related to shipbuilding center shafting Boring preciseness, specifically a kind of boring row calibration tool.
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, the front and rear axis hole of stern tube is all set
Unilateral 15-30mm bore hole surplus has been counted, has been manufactured and the produced deformation of general assembly carrying for compensating boat segmental, and this
Bore hole surplus carries out boring after determining center line of shafting in being looked for after ship carrying by shafting.
Stern tube boring work usual way be：Processing circle determined by being looked for according to shafting is (i.e. with shafting in practice
The heart is the center of circle, requires finish size as radius circle drawn on stern tube front/rear end using stern pipe) it is processing foundation, to examine
Circle (radius is more than the concentric circles of processing circle) verifies foundation for the row of warding off.And according to《CSQS (CSQS)》It is required that,
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 ensure Boring preciseness, it is necessary to carry out the boring work of shafting.
, it is necessary to which processing circle is used for multiple times and circle progress tune-up boring row is examined during bore hole, but drawn processing circle
0.1mm will be exceeded with the width of round line of inspection itself, it is difficult to ensure that circularity and cylindricity are less than 0.05mm required precision.
In summary, in current work progress, a kind of simple, fast and effectively boring row calibration tool and verification is lacked
Method, these installations on marine shafting and follow-up Ship Propeling performance produce influence.
Utility model content
There is provided a kind of boring row calibration tool and verification side for the above-mentioned the deficiencies in the prior art that aim to overcome that of utility model
Method, to ensure the finish size of stern tube.
Technical solution of the present utility model is as follows：
A kind of boring row calibration tool, including a L-type fixed block and a stud being arranged on the L-type fixed block, should
One end of stud is tapered to be provided with screwed hole, the diameter phase of the internal diameter of the screwed hole and described stud on described fixed block
Adaptation.
Described fixed block is processed by the common iron of in the market or Steel material.
Described stud is that in the market plain bolt is processed.
The method that boring row verification is carried out using described boring row calibration tool, this method is comprised the following steps：
1. Ship Structure, which reaches, looks for after middle requirement, during progress first time shafting is looked for, determines shafting theoretical centerline；
2. draw processing circle according to the front/rear end of the theoretical centerline of determination axis hole before and after stern tube and examine and justify；
3. four L-type fixed blocks, the centrally directed axial center of screw of fixed block are welded in the front/rear end of front and rear axis hole
Line；
4. taper stud is screwed on, and the difference being finely adjusted to stud tip to axial center's linear distance is less than 0.02mm,
Spot welding is fixed；
5. taper stud is checked again for axial center's distance, and such as deviation is more than 0.02mm, uses abrasive machine or sand paper pair
Taper stud carries out polishing amendment；
6. when school is arranged, boring row is measured to the distance of taper stud using inside micrometer, 4 differences are less than 0.05mm, said
Bright school row is qualified, and otherwise return to step is 5..
It is Q235 or other similar materials that described L-type, which fixes stock material, is simultaneously machined with the screwed hole run through, spiral shell
Line size M12 to M20.
Corresponding 8.8 grades of nigrescence bolts can be used to process for described taper stud, and one end processing is tapered, at minimum
1~2mm of diameter, its screw thread matches with L-type fixed block.
Compared with prior art, the beneficial effects of the utility model are
1) add a school for being accurate to the 0.01mm orders of magnitude and list and index and test benchmark, school row's precision can be increased substantially.
2) manufacture and material cost are relatively low；
3) it is able to ensure that stern tube boring finish size meets code requirement；
4) ship of the applicable object for progress stern tube shaft bore hole in need.
