Abstract

The invention relates to the technical field of welding, and discloses an anti-eccentric clamping device for circular hard alloy welding. The device comprises a workbench, a sliding groove is formed at the top of the workbench, a screw rod is movably connected to the left side of the workbench, a gap adjusting handle is fixedly connected to the left side of the screw rod, and a sliding seat is slidably connected to the interior of the sliding groove; and a disc body is fixedly connected to the top of the sliding seat, a fixing sleeve is slidably connected to the interior of the disc body, and an adjusting groove is formed in the inner wall of the disc body. Welding bodies are gradually clamped by a clamp at the end, close to the welding bodies, of a clamping rod, meanwhile, the axes of the welding bodies coincide with the axis of the disc body, the axes of the welding bodies at the two sides coincide with the axis of the disc body, the axes of the two welding bodies coincide, and therefore the purpose that the welding axes are aligned is achieved; and meanwhile, as the structure is simple and the axis alignment is not influenced by different diameters of the two welding bodies, the application range is wide.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a circular hard alloy welding anti-eccentric clamping device. Background technique [0002] Cemented carbide is a kind of cermet tool material prepared by powder metallurgy method with refractory metal compound (WC, TaC, TiC, NbC, etc.) as matrix and transition metal (Co, Fe, Ni) as binder phase. , the material of cemented carbide is brittle and hard, poor toughness and high price. These factors make it difficult to be used in large-sized and complex-shaped components, and the welding of cemented carbide and steel body materials is the main method to make up for its shortcomings. . [0003] When welding round hard alloys, since most of the existing welding is manual welding, it is difficult to align the axes during welding, and the eccentric phenomenon of round hard alloys is prone to occur, which affects its performance. At the same time, the welding gap is not good Be sure, ...
