Description

Tool for adjusting boring row center of stern tube boring hole

Technical Field

The utility model relates to a shipbuilding field, concretely relates to frock of boring row center adjustment of boats and ships stern tube bore hole.

Background

The stern tube boring process is mainly used for an ultra-large bulk cargo ship or an ore carrier, and the key is how to accurately erect a boring bar and ensure that the center of the boring bar is recombined with the theoretical center line of a shaft system in the boring process. If the boring bar is erected to have deviation, deviation between the center of the shaft hole and the theoretical center line of the shaft system can be caused, high temperature can be caused to a propeller shaft bearing, and the bearing can be damaged seriously. The conventional boring bar is erected according to a detection circle center of the end part of a tail casting drawn during line drawing and lighting, the detection circle error is about 0.3mm, and the error is too large.

Disclosure of Invention

For solving among the prior art boats and ships stern tube be the great problem of error in confirming the bore hole central line, the utility model aims to provide a satisfy bore hole concentricity 0.05 mm's requirement a frock that is used for the boring of stern tube bore hole to arrange the central adjustment.

In order to achieve the above purpose, the utility model adopts the technical proposal that:

the utility model provides a frock that is used for boring of stern tube bore hole to arrange central adjustment, is including looking at light appearance, light target, looking at light appearance support and adjustment installation device, light target includes head light target and tail light target, the inboard at the head and the tail both ends of stern tube is installed to head and tail light target, look at light appearance through looking at light appearance support mounting at stern tube end face, adjustment installation device includes barrel and the marking off pole through the barrel axis, the barrel with look at the coaxial cover of light appearance in looking at light appearance support, be threaded connection between marking off pole and barrel, be equipped with the marking off tip of perpendicular marking off pole on the marking off pole.

Further, look at light appearance support and include outer barrel and interior barrel, four adjusting screw are installed along the diameter direction equipartition to outer barrel, adjusting screw is towards the outer side direction of urceolus body, it is internal that interior barrel passes the fix with screw of outer barrel by the round in the urceolus, look at light appearance coaxial arrangement in the inner tube, barrel and rotation in the barrel of adjustment installation device inserts, and the external diameter and the interior barrel internal diameter of adjustment installation device barrel are the same.

And furthermore, four screw supports are welded on the end surface of the stern tube at intervals of 90 degrees, and the adjusting screws are matched with the screw supports.

After taking above technical scheme, the beneficial effects of the utility model are that: through supposing the sighting device support, through the axis position of sighting device support adjustment, erect adjustment installation device as the benchmark at the support after the adjustment to the processing axis of adjustment installation device marking off definite bore hole, this technical scheme can effective control and improve the boring row and erect the accuracy.

FIG. 3 is a schematic view of an adjusting device;

FIG. 4 is a schematic view of an illuminated light target.

Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings:

as shown in the figure, the tool for adjusting the boring center of the boring bar for boring the stern tube consists of a light sighting device 1, a light sighting target 2, a light sighting device bracket 3 and an adjusting and mounting device 4, wherein the light sighting target comprises a head sighting target and a tail sighting target, and the head sighting target and the tail sighting target are mounted on the inner sides of the head end and the tail end of the stern tube. As shown in fig. 1, four screw supports 8 are welded on the end surface of the stern tube at intervals of 90 °. As shown in fig. 2, the collimator support 3 comprises an outer cylinder 5 and an inner cylinder 6, four adjusting screws 7 are uniformly arranged in the middle of the outer cylinder along the diameter direction, the four adjusting screws 7 are arranged on the same plane, the adjusting screws 7 face the outer side direction of the outer cylinder and abut against four screw supports 8, and the collimator support 3 is fixed on the end surface of the stern tube. The inner cylinder 6 is fixed in the outer cylinder 5 by a circle of uniformly distributed screws 9 penetrating through the outer cylinder, and the collimator 1 is coaxially arranged in the inner cylinder 6. As shown in figure 3, the adjusting and mounting device comprises a cylinder body 10 and a scribing rod 11 passing through the axis of the cylinder body, wherein the scribing rod 11 is in threaded connection with the cylinder body 10, and a scribing tip 12 vertical to the scribing rod is arranged on the scribing rod 11. The telescope 1 is cooperated with the illumination light target 2, and the telescope is coaxial with the axis of the stern tube by adjusting four adjusting screws 7, and the axis of the inner cylinder 6 of the telescope support 3 is consistent with the axis of the stern tube. The external diameter of barrel 10 is the same with 6 internal diameters of interior barrel, barrel 10 and light, 1 coaxial arrangement in light observation appearance support 3, perhaps installs barrel 10 in light observation appearance support 3 after dismantling light observation appearance 1, and barrel 10 is at interior barrel 6 and rotate, and marking off rod 11 drives and draws a line tip 12 at the stern tube end surface and rule, forms the benchmark of stern tube bore hole processing.

The use method of the device comprises the following steps: the lighting light target 2 is installed, and the telescope support 3 is arranged at the end part of the stern tube, so that the center of the telescope is coincided with the theoretical central line. When the center of the telescope 1 coincides with the center line of the theoretical shaft system, the telescope is removed and the telescope support 3 is used for fixing, adjusting and mounting the device 4. And drawing a processing standard on the end surface of the stern tube after the stern tube is fixed.
