Embodiment Construction

[0026] In order to fully understand the purpose, features and effects of the present invention, the present invention will be described in detail through the following specific embodiments, but the present invention is not limited thereto.

[0027] see Figure 1 to Figure 3 , a kind of marine multi-fulcrum boring bar horizontal positioning and sinking amount detection and compensation method provided by the present invention is carried out according to the following steps:

[0028] S1. Insert the boring bar 1 into the stern tube 2, fix the head fixing bracket 4 and the tail fixing bracket 3 with the hull as a whole, and install the intermediate support bracket 5 in the stern tube 2 for auxiliary support And fixed boring row boring bar 1.

[0029] S2. Use the inner diameter micrometer 6 to measure the distance between the boring bar 1 and the stern tube 2 at the positions of the head fixing bracket 4 and the tail fixing bracket 3 of the boring bar 1, and adjust the radial adju...

Abstract

The invention discloses a horizontal positioning and sinkage detection compensation method for a marine multi-fulcrum boring machine boring rod, and relates to the technical field of ship construction. According to the horizontal positioning and sinkage detection compensation method, the sinkage of the boring rod is detected by utilizing a straightness detection function of a signal instrument, and the boring rod at head and tail brackets is positioned at the central point of the cross section of a tail shaft tube by adjusting the head and tail brackets of a boring machine. The head and tail brackets serve as base points, the straightness of all points on the upper surface of the boring rod for the head base point and the tail base point is detected through the signal instrument, and the sinkage of all the points of the boring rod is reflected through a straightness curve generated by a signal data processing terminal. According to the sinkage curve of the boring rod, adjusting bolts of a middle support are adjusted, supporting compensation is conducted on the sinkage of the boring rod, through multiple times of detection and adjustment, the sinkage of the multi-fulcrum boring rod is finally eliminated, and the machining precision of the tail shaft tube by the boring machine is ensured.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a method for horizontal positioning and sinking amount detection and compensation of a multi-fulcrum boring bar for a ship. Background technique [0002] In the boring processing of large steel structures such as ship shafts and rudder systems, large bridges, hydropower stations, and petrochemical industries, large boring rows are widely used for boring construction. Before boring the shafting of the ship, it is necessary to fix the first and last ends of the boring row on the non-processed end face of the steel structure to be bored, and then perform alignment processing on the boring bar of the boring bar to ensure that the center line of the boring bar is in line with the steel structure to be bored. The structure is in a concentric state, so that the shaft hole of the stern tube can meet the concentricity tolerance requirements after machining. During the machining of s...
