A b-shaped lifting ring assembly and positioning tool

Abstract

The invention discloses a B-type lifting ring assembly and positioning tool, which includes an assembly platform, a positioning baffle is vertically installed on the upper surface of the assembly platform, and a limit block parallel to the positioning baffle is installed on the side of the assembly platform. Higher than the upper surface of the assembly platform, there is at least one first centering scale line on the positioning baffle, at least one second centering scale line on the limit stopper, and a notch on the bottom of the positioning baffle . Locate the lug plate and the backing plate of the B-type lifting ring. The side of the backing plate is fitted with the limit stopper and the large end surface of the ear plate is fitted with the positioning baffle, so that the backing plate and the lug plate are perpendicular to each other and in the width direction. For centering, align the vertical side of the lug plate and the short side of the backing plate with the first centering scale line and the second centering scale line respectively, so as to realize the centering of the backing plate and the ear plate in the length direction, and the whole structure The design is simple, the positioning operation is fast, and the precision is high, and the invention 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.
