The utility model belongs to the technical field of radiator core
brazing, and particularly relates to a radiator core
brazing fixing tool which comprises a base, two adjusting blocks are symmetrically arranged at the top end of the base, and a two-way
threaded rod is assembled in the base. The distance between the two adjusting blocks can be adjusted through matching of the two-way
threaded rod and the threaded sleeve, and alignment of the left side and the right side of a radiator core body is achieved. And then, through the synergistic effect of a sliding block, a first guide rod, a
butt joint block, a first
threaded rod, a second threaded rod and an adjusting sleeve, the distance between the two clamping blocks can be flexibly adjusted, and it is ensured that the front end and the rear end of the radiator core are aligned. Finally, through linkage cooperation of the
extrusion block, the third threaded rod and the fixing block, reliable clamping force is formed between the descending
extrusion block and the base, the radiator core is stably fixed to the tool, in this way, the stability of the radiator core on the fixing tool is guaranteed, and the production efficiency is improved. And meanwhile, the problem that the
brazing efficiency is influenced by complexity and long time of adopting multiple groups of supporting rods and nuts is also reduced.
