Problems solved by technology
[0002] Because of the structure and assembly requirements of the wire tube evaporator, it is necessary to strengthen the spot welding between the inlet pipe or the outlet pipe and the serpentine coil. The air pipe and the serpentine coil are fixed, and then welded on one side of the fixed point by flame welding. After the welding is completed, the wire tube evaporator is turned over (turned over), clamped by a flat welding fixture, and welded on the other side. Once, the operation of the prior art uses two-sided welding, which not only has low production efficiency but also wastes solder. In addition, the welding operation is performed on both sides of the same point, and there will be gaps between the welding points, and the subsequent powder spraying of the product cannot be done. Complete coverage, installed in the refrigerator for long-term use, corrosion, rust, air leakage and other defects will occur. Therefore, it is necessary to study a welding tool that can achieve the welding effect in one welding

The invention relates to the field of tool clamps, in particular to a filament tube evaporator fixing point welding tool. The tool includes a support, a plurality of mounting plates are arranged at the top end of the support, and the fixing bolt mechanisms are arranged on the mounting plates and comprise the supporting plates which are welded with the mounting plates at an angle of 90 degrees; twolimiting plates are welded to each supporting plate, a limiting groove is formed between the two limiting plates, and a limiting block is arranged in the limiting groove and is fixed to the supporting plate through a bolt; a pin cylinder is arranged at the upper end of the limiting block, a through hexagonal through hole is formed in the pin cylinder, and a pin is arranged in the hexagonal through hole. According to the present invention, by adopting a mode of vertically fixing a product, the fixing point, needing to be welded, of a filament tube evaporator is installed in the limiting grooveformed by the two limiting plates, the welding point is fixed in the vertical direction through the pin and the limiting block, and then the filament tube evaporator is welded at the right middle position of the two tubes at the fixing point.
