B-type hanging ring assembling and positioning tooling

Abstract

The invention discloses B-type hanging ring assembling and positioning tooling. The B-type hanging ring assembling and positioning tooling comprises an assembling platform, a positioning baffle is perpendicularly mounted on the upper surface of the assembling platform, a limiting stop block parallel to the positioning baffle is mounted on the side face of the assembling platform, and the limitingstop block is higher than the upper surface of the assembling platform; and the positioning baffle is provided with at least one first centering scale line, the limiting stop block is provided with atleast one second centering scale line, and a groove opening is formed in the bottom of the positioning baffle. A lug plate and a backing plate of a B-type hanging ring are positioned, the side face of the backing plate is attached to the limiting stop block, and the large end face of the lug plate is attached to the positioning baffle, so that the backing plate and the lug plate are perpendicularto each other and centered in the width direction; the vertical side face of the lug plate and the short edge of the backing plate are correspondingly aligned with the first centering scale lines andthe second centering scale lines, so that centering of the backing plate and the lug plate in the length direction is achieved; and the overall structural design is simple, positioning operation is fast, the precision is high, and the B-type hanging ring assembling and positioning tooling is used in the field of ship accessories.

Description

technical field [0001] The invention relates to the field of ship accessories, in particular to a B-type lifting ring assembly and positioning tool. Background technique [0002] B-type lifting rings are commonly used in the shipbuilding industry and are installed on hull segments for hanging wire ropes for lifting. The B-type lifting ring is composed of an ear plate and a rectangular backing plate, and the ear plate is fixedly installed on the backing plate by welding. Theoretically, the ear plate and the backing plate are assembled in the center, and the ear plate should be in the center of the backing plate and perpendicular to the backing plate. In the past, when the lifting ring was welded by hand, the centering assembly and positioning requirements of the lug plate and the backing plate were not high, and the centering was mostly performed by pure visual inspection without tool assistance, and the centering deviation had little effect on welding. However, when the li...

Problems solved by technology

However, when the lifting ring is automatically welded by the robot's high-pressure contact type automatic detection of the groove, it is more sensitive to assembly deviation. If there is a deviation in the centering of the lifting lug, the robot will easily bend the fixed and elongated welding wire on the welding torch in the empty state, resulting in It is no longer possible to use welding wire for normal groove detection, that is, when using robot automatic welding, the lug plate and the backing plate must have a high centering assembly positioning accuracy

B-type lifting ring has four commonly used specifications. At present, there is no special auxiliary assembly tooling, which can realize the fast and accurate positioning of the lug plate and backing plate of the B-type lifting ring of four specifications.
