Abstract

The utility model belongs to the technical field of radiator core brazing, and particularly relates to a radiator core brazing fixing tool. According to the utility model, the distance between the two adjusting blocks can be adjusted through the cooperation of the bidirectional threaded rod and the threaded sleeve, so that the alignment of the left side and the right side of the radiator core is realized. Then, the distance between the two clamping blocks can be flexibly adjusted by utilizing the synergistic effect of the sliding block, the first guide rod, the butt joint block, the first threaded rod, the second threaded rod and the adjusting sleeve, so that the alignment of the front end and the rear end of the radiator core body is ensured. Finally, through the linkage cooperation of extrusion piece, third threaded rod and fixed block, the extrusion piece that descends forms reliable clamping force with the base, is firmly fixed in the frock with the radiator core, has both ensured the stability of radiator core on fixed frock like this, also reduces simultaneously and adopts the loaded down with trivial details and the long problem that influences brazing efficiency of time of multiunit bracing piece and nut.

Description

Radiator core fixed frock that brazes Technical Field The utility model belongs to the technical field of radiator core brazing, and particularly relates to a radiator core brazing fixing tool. Background The radiator core is used as a core component of the radiator and mainly comprises a radiating pipe, radiating fins and a collecting pipe. The heat dissipation pipe is of an elongated tubular structure and is used for carrying heat medium and transferring heat, the shape, the size and the arrangement mode of the heat dissipation pipe affect heat dissipation efficiency, the heat dissipation fins are closely attached to the periphery of the heat dissipation pipe, the heat dissipation effect is improved by increasing the heat dissipation area and optimizing air flow, and the collecting pipe is used for collecting and distributing the heat medium and guaranteeing heat dissipation uniformity. At present, the radiator core body commonly adopts a brazing process to finish the connection operation of all the components. In the process flow, the radiating pipe and the radiating fin are fixed by means of a fixing tool. However, the current mainstream fixing tool design scheme has the obvious disadvantage that most of fixing tools are fixed by adopting a combined structure of supporting rods and nuts, and particularly, the fixing plate is clamped on the outer wall of the radiator core through the synergistic effect of a plurality of groups of supporting rods and the nuts, so that the fixing effect is achieved. It is noted that such a fixing typically requires at least 4 sets of support rods and nuts. The redundant use of the plurality of groups of nuts and the supporting rods not only greatly increases the complicated degree of the core fixing operation of the radiator, but also remarkably prolongs the time consumption of the fixing operation and negatively affects the production efficiency. Disclosure of utility model The utility model aims to provide a radiator core brazing fixing tool, and aims to solve the problem that most of the existing combined structures adopting supporting rods and nuts are adopted for fixing in the prior art, and particularly, a fixing plate is clamped on the outer wall of a radiator core through the synergistic effect of a plurality of groups of supporting rods and nuts, so that the fixing effect is achieved. It is noted that such a fixing typically requires at least 4 sets of support rods and nuts. The redundant use of the plurality of groups of nuts and the supporting rods not only greatly increases the complicated degree of the core fixing operation of the radiator, but also remarkably prolongs the time consumption of the fixing operation and solves the problem of negative influence on the production efficiency. In order to achieve the purpose, the technical scheme is that the radiator core brazing fixing tool comprises a base, wherein two adjusting blocks are symmetrically arranged at the top end of the base, a bidirectional threaded rod is assembled in the base, two threaded sleeves are symmetrically connected to the surface of the bidirectional threaded rod in a threaded mode, the threaded sleeves are connected with the adjusting blocks, clamping blocks are arranged on the corresponding side walls of the two adjusting blocks, two sliding blocks are symmetrically and slidably connected to the inside of the adjusting blocks, a first guide rod is arranged in the adjusting blocks, a butt joint block is connected to the top ends of the two sliding blocks, a first threaded rod and a second threaded rod are connected to the corresponding side walls of the two butt joint blocks, an adjusting sleeve is connected between the first threaded rod and the second threaded rod, a fixing block is arranged on the corresponding side wall of the two adjusting blocks, a third threaded rod is connected to the surface of the fixing block in a threaded mode, and a squeezing block is arranged at the end of the third threaded rod. As the preferable welding fixture for the radiator core body, the bidirectional threaded rod can be rotatably connected with the base through the bearing, and the adjusting block can form threaded movement with the bidirectional threaded rod through the threaded sleeve. As the preferable welding fixture for the radiator core body, the screw threads on the surfaces of the first threaded rod and the second threaded rod are opposite, and the clamping block can form screw thread movement with the base through the sliding block, the first guide rod, the butt joint block, the first threaded rod, the second threaded rod and the adjusting sleeve. As the radiator core brazing fixing tool, the extrusion block can be connected with the base in a lifting mode through the third threaded rod and the fixing block. As the radiator core brazing fixing tool disclosed by the utility model is preferable, one end of the base is provided with the supporting block, the inner side wall of the supporting b
