Abstract

The invention relates to a bridge support welding tool. The tool comprises locating block assemblies and pressing-jacking assemblies. The locating block assemblies are used for coating the four corners of a bridge support for pressing and locating. Each locating block assembly at least comprises a locating structure matched with a bottom plate, a middle flat plate and left / right side plates. The corresponding locating structures are used for limiting the position among the middle flat plate, the left side plate, the right side plate and the bottom plate. Each pressing-jacking assembly comprises a magnetic seat and telescopic supporting arms arranged on the two sides of the magnetic seat. The magnetic seats are used for being arranged over the middle flat plate to press the middle flat plate onto the upper surface of the bottom plate, and the telescopic supporting arms on the two sides press the left side plate and the right side plate to the inner surfaces of a left flange and a rightflange correspondingly through supporting ends.

Description

technical field [0001] The invention relates to the technical field of metal welding, in particular to a bridge support welding tool. Background technique [0002] The bridge support is an important part of the beam and slab bridge structure, and it is a force transmission device installed at the support of the bridge span structure and the bridge pier or abutment. Such as figure 1 As shown, it is a commonly used series of bridge bearing products. The bridge bearing 10 is a metal assembly composed of a bottom plate 11, a middle plate 12, and a left side plate 13 and a right side plate 14 placed on the two inner sides. The peripheral parts of the middle plate 12, the left side plate 13 and the right side plate 14 need to be automatically welded on the bottom plate 11 by a robot. Before automatic welding, it is necessary to use fixture tooling to position each part to ensure certain dimensional accuracy requirements. After positioning, it is necessary to press the surface, ...
