Rotator for welding box-shaped structural member

Abstract

The invention discloses a rotator for welding a box-shaped structural member, which comprises two rotating track supporting mechanisms formed by annular groove-shaped tracks and intra-annular rectangular frames, wherein pin wheels are welded on axial end surfaces of the rotating track supporting mechanisms, and two sets of symmetrical supporting roller systems are arranged at the lower ends of the rotating track supporting mechanisms; each set of the supporting roller system comprises a supporting roller seat which is fixed on a base and is articulated with a supporting roller frame, and supporting rollers are symmetrically arranged at two sides at the upper part of the supporting roller frame and are embedded into the annular groove-shaped tracks; gears which are meshed with the pin wheels are concentrically installed on the supporting rollers at different axes; each supporting roller seat is connected with two side supporting frames through a tension adjuster, the lower ends of the supporting frames are articulated with the base, and the upper ends of the supporting frames are fixedly connected with a guide roller mechanism through supporting frame seat boards; and traveling steel wheels which are embedded into a traveling track are arranged on the bottom surface of the base, and fixing devices are arranged at two sides of the base. The rotator of the invention can freely turn the welded box-shaped structural member at any time in the welding process, thereby turning a welding bead to the optimal angle for welding.

Description

technical field [0001] The invention relates to an auxiliary device in the welding process, in particular to a rotating machine used for fixing and turning over the welded structure during the welding process of the box-shaped steel structure. Background technique [0002] At present, box-type structures are very common in the manufacture of steel structures, such as crane girders, bridge-building box girders, containers, etc. are all box-type structural parts. These box-shaped structural parts, especially large-scale box-shaped structural parts, have relatively high requirements for weld quality and dimensional accuracy, and due to the large cross-sectional size and high rigidity, once the deformation occurs after welding, it cannot be corrected. Therefore, it is very critical to control the welding deformation in the welding manufacturing process. [0003] In order to effectively control welding deformation, reasonable measures need to be taken in various aspects such as ...

AI Technical Summary

Problems solved by technology

In existing production, hooks are usually used to turn over and fix the welded structural parts to adjust the angle to carry out welding. In this way, not only the work efficiency is low, the weld quality is poor, and there are many operators involved, but also increased The difficulty of work brings more safety hazards

Especially for large box-shaped structural parts and mass production, it increases the difficulty and danger of production
