The invention discloses a welding fixture for H-shaped steel in the technical field of steel structure production. The welding fixture for the H-shaped steel comprises a pressing component; the pressing component comprises a base and two groups of movable frames with the same structure; guide rails connected with the movable frames in a sliding mode are arranged around the top of the base; support blocks are arranged on the opposite sides of the two groups of movable frames; placing blocks are movably connected to the tops of the supporting blocks in an inserted mode; the placing blocks are fixedly connected with the end parts of pressing rods; the two groups of pressing rods are arranged; the pressing rods can move downwards to a certain height through the supporting blocks on the movable frames, so that follow-up assembling of the pressing rods is facilitated; and the placing blocks capable of being connected to the supporting blocks in an inserted mode are arranged at the end parts of the pressing rods; and when the pressing rods are assembled, the placing blocks are firstly aligned and inserted on the supporting blocks and then are fixed through bolts, so that the assembly is greatly facilitated.
Description
technical field [0001] The invention relates to the technical field of steel structure production, in particular to a welding fixture for H-shaped steel. Background technique [0002] Welded H-shaped steel, named for the H-shaped section made by welding technology, is divided into submerged arc welded H-shaped steel and high-frequency welded H-shaped steel. The process of submerged arc welding H-shaped steel: steel plate - automatic slitting - assembly - automatic submerged arc welding - flaw detection - flange correction - web correction - end surface processing - sandblasting and rust removal - painting . [0003] Before the automatic submerged arc welding, it is necessary to press and position the assembly plate through the welding fixture. The current welding fixture generally presses the flanges on both sides through the liftable pressure rod, so that the flange does not warp upwards, and then through the positioning on both sides The plate is positioned and clamped t...
