Problems solved by technology

This method of setting the process hole needs to be restored by welding after the stern tube is processed. The disadvantage is that the coaxiality of the head and tail inner holes of the processed stern tube becomes too large, and finally affects the assembly quality of the stern tube.

Embodiment Construction

[0020] The present invention is to complete the boring process of the inner holes of the bearing hubs of the ship shafting system. In order to ensure the coaxiality of the axes of the bearing hubs, the boring bar must have good straightness, because the ratio of the diameter to the length of the boring bar is generally Between 1:25-1:40, it belongs to the slender rod structure, it is difficult to ensure the straightness of the axis of the boring bar with two support points, so a support point should be added in the middle of the boring bar. The special intermediate support can be adjusted externally by the operator without opening the process hole in the stern tube, so as to eliminate the deflection of the boring bar and make the axis of the boring bar coincide with the axis of the hull.

[0021] The erection process of ship stern tube boring tooling, the process steps are as follows:

[0022] 1. See Figure 3 for the determination of the position of the intermediate support in...

Abstract

The present invention belongs to a ship stern tube boring tool mounting process. Said process includes the following several procedures: defining the position of intermediate support of boring bar in the stern tube to be machined; measuring straightness of boring bar; simulatively measuring flexibility value of cantilevers of two ends of said boring bar; and mounting boring tool. Said invention also provides the concrete steps of the above-mentioned every procedure.

Description

(1) Technical field [0001] The invention relates to a machining boring process equipment, in particular to a ship stern tube boring tool erection process. (2) Background technology [0002] During the ship construction process, the head and tail bearing parts in the stern tube need to be bored. In order to ensure the coaxiality of the inner holes of the head and tail ends after processing, the boring bar must have good straightness. Usually, a special tool is installed in the middle of the boring bar. The tooling is supported in the middle to avoid the deformation of the boring bar and maintain the straightness of the boring bar. In the past, the stern tube processing method was to process the non-processed part into a process hole for people to enter and exit. The constructor can enter the tube outside the stern tube and through the process hole, and use the reference point as the reference to center the boring bar respectively. Positive, making the axis of the boring bar ...
