Positioning tool for steel structure welding

Abstract

The invention discloses a positioning tool for steel structure welding, and relates to the technical field of welding. The positioning tool comprises a bearing plate, wherein limiting grooves are symmetrically formed in the top of the bearing plate, movable plates are movably clamped in inner cavities of the two limiting grooves, extension rods are fixedly connected to the bottoms of the two movable plates, threaded rods are fixedly connected to the bottom ends of the two extension rods, the bottom ends of the two threaded rods are movably connected with the bottoms of the inner walls of the two limiting grooves in a penetrating mode correspondingly, locking pieces are in threaded connection with the positions, located below the bearing plate, of the outer walls of the two threaded rods, rotating blocks are fixedly connected to the bottom ends of the two threaded rods, and positioning blocks are arranged at the tops of the two movable plates. According to the positioning tool for steelstructure welding, the movable plates and the rotating blocks are arranged, the rotating blocks are moved and rotated to drive the movable plates to be disengaged from the limiting grooves, rotate bya certain angle, and then enter the limiting grooves again, positioning work on steel structures in different directions is achieved, and the applicability of the positioning tool for steel structurewelding is improved.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a steel structure welding positioning tool. Background technique [0002] Steel structure is a structure composed of steel materials, which is one of the main types of building structures. The structure is mainly composed of beam steel, steel column, steel truss and other components made of section steel and steel plate, and adopts rust removal and antirust processes such as silanization, pure manganese phosphating, washing and drying, and galvanizing. The components or components are usually connected by welds, bolts or rivets. Because of its light weight and easy construction, it is widely used in large factories, stadiums, super high-rises and other fields. Steel structures are prone to corrosion. Generally, steel structures need to be derusted, galvanized or painted, and they need to be maintained regularly. [0003] When welding steel structures, it is generally necessar...

Problems solved by technology

[0003] When welding steel structures, it is generally necessary to use positioning tooling to position the steel structure to be welded to prevent the position of the steel structure from shifting during welding, which will affect the quality of the welding work. Nowadays, positioning tooling is used for steel structures, and its structure It is relatively simple and can only be used for positioning the steel structure in a specific direction, so its applicability is low. At the same time, the positioning surface of the positioning tool for the steel structure is mostly set horizontally. Certain difficulties, increasing the difficulty of welding work
