Alignment clamp with top opening and 360-degree rotation function

Abstract

The invention discloses an alignment clamp with a top opening and the 360-degree rotation function. The alignment clamp with the top opening and the 360-degree rotation function is a clamping and turnover device for welding a weld assembly which is of a long-box-shaped steel structure, can achieve rapid clamping and high-accuracy and 360-degree continuous rotation of the weld assembly of the long-box-shaped steel structure, and can stop at any position. When the center of gravity of the weld assembly of the long-box-shaped steel structure and the alignment clamp with the top opening and the 360-degree rotation function do not share the same axis, the center of gravity of the weld assembly of the long-box-shaped steel structure can coincide with the center of rotation by adjusting the positions of three sliding plates. The alignment clamp with the top opening and the 360-degree rotation function comprises a rack, a rotation mechanism, an electric clamping mechanism and a safety mechanism.

Description

technical field [0001] The invention relates to the field of welded parts for steel structures, in particular to a 360-degree rotating centering fixture with an upper opening. Background technique [0002] In recent years, with the development of welding technology, the level of industrial automation has made great progress, and the application of steel structure welded parts has become more and more extensive. The supporting flipping device in the production process of steel structure welded parts has also developed in a blowout style. [0003] At present, in the welding of long box-shaped steel structure weldments, there are mainly two kinds of clamping and turning devices as follows: [0004] One way is to install a clamping turning mechanism for a ring turning machine, which is mainly composed of driven rollers, driving rollers, hinges, lock seats, support wheels, driving motors, clamping mechanisms and other components. The turning circle is divided into upper and lowe...

AI Technical Summary

Problems solved by technology

However, the problem with this clamping method is that the roller is used for positioning in the radial direction, and the pressing block and roller are used for positioning in the axial direction, so the positioning accuracy is very poor; The swing of the steel structure welded parts in a small angle range is far from meeting the requirements of the existing steel structure parts for the welding station

[0006] Therefore the card loading problem that existing card loading mode exists needs to be solved urgently
