Coaxial measuring tool and measuring method

Abstract

The invention relates to the measuring tool set up and method for axiality of axial line of axial line of main engine of ship and basis points of head and tail , The measuring tool set up includes two same light pipes on the head and tail, two light targets and four supports of light targets, two target plates supports of head and tail, two base tool set up and micrometer ordination axis of inside diameter. The measuring steps are as follows: the target plate supports of the head and tail are put separately on basis points of head and tail of the ship, telescope is used to build a axial line of head and tail; the light targets are separately installed on the front and back ends of head and tail light pipes in the main axis pipe, the telescope is used to adjust the support of head and tail light pipes , making the center of light targets on head and tail light pipes on the axial line of head and tail ; the final orientation basis points of axial line is used to process the light pipes; the telescope is used to mark the axial line of head and tail of main axial hole and by the difference of the middle point of axial line, is acquired. Its advantages are accurate orientation of main axial, high efficiency.

Description

(1) Technical field [0001] The invention relates to the measurement of coaxiality, in particular to a measurement tool and a measurement method for the coaxiality of a reference axis set between the main engine axis of a ship and a given bow base point and stern base point of the ship. (2) Background technology [0002] The positioning and installation of the shafting of the main engine of the ship is very important in shipbuilding. At present, most of the positioning of the main shafting of various ships still uses the original wire drawing method, that is, connecting the given bow base point and stern base point of the hull with a thin steel wire of Φ0.5mm, and then Use this steel wire as the axis of the main engine to adjust. This method has poor coaxiality, and the coaxial error directly affects the efficiency and energy consumption of the main engine. The adjustment process of the main engine is labor-intensive and the work efficiency is low. In addition, it is operati...

[0002] The positioning and installation of the shafting of the main engine of the ship is very important in shipbuilding. At present, most of the positioning of the main shafting of various ships still uses the original wire drawing method, that is, connecting the given bow base point and stern base point of the hull with a thin steel wire of Φ0.5mm, and then Use this steel wire as the axis of the main engine to adjust. This method has poor coaxiality, and the coaxial error directly affects the efficiency and energy consumption of the main engine.

The host adjustment process is labor-intensive and low-efficiency

In addition, it is working in the open air, and cannot work in case of strong wind

The amount of steel wire sag is an uncertain factor, and the calculated amount of steel wire sag will not be accurate. The final product delivery inspection is not intuitive, which may easily cause disputes with shipowners, which is not conducive to market competition.
