Auxiliary shape rectification welding tool for circular ring part quick clamping

Abstract

The invention discloses an auxiliary shape rectification welding tool for circular ring part quick clamping, and belongs to the field of welding tools. The auxiliary shape rectification welding tool comprises a bracket and a shape rectification fixing device rotationally erected on the bracket. The shape rectification fixing device comprises a base, an inner wall positioning mechanism, an outer wall positioning mechanism and a pressing mechanism. A welded circular ring part is fixed at multiple points by using multiple groups of mutually matched inner wall clamping blocks and outer wall clamping blocks, so that clamping and fixing are stable and reliable; and the inner wall clamping blocks and the outer wall clamping blocks synchronously stretch and retract inside and outside, so that a certain rectification function can be achieved on the welded circular ring part. In addition, in the clamping process of the inner wall clamping blocks and the outer wall clamping blocks, the pressing mechanism can be synchronously driven for linkage and downward pressing, and the upper portion of the welded circular ring part is pressed and fixed, so that clamping is more rapid and convenient, andthe clamping efficiency and stability are improved. Meanwhile, the inner wall clamping blocks and the outer wall clamping blocks can be moved and adjusted inside and outside radially in the circumferential direction, welding requirements of welded circular ring parts in different sizes can be met, and the product adaptability is high.

Description

technical field [0001] The invention relates to a welding tool, in particular to a fast clamping auxiliary orthopedic welding tool for a circular ring. Background technique [0002] With the development of industrial technology, ring-shaped rods or pipes are often used as supporting components in aviation, aerospace, ships, automobiles and other fields. Larger-sized ring-shaped rods or pipes are usually bent first. Bending is done in the machine to form a ring, and the ends are welded to shape. [0003] Due to the residual welding stress generated during the welding process, the ring parts will be severely deformed, causing the ring parts to warp or be out of round. Usually, it is necessary to use special fixtures to assist the welding of the ring parts. The welding process of the ring parts is improved, such as "A Welding Method for Aluminum Alloy Hollow Ring Parts" disclosed in Chinese Patent Application No. 201310693257.5, the welding method of the aluminum alloy hollow ...
