Constraint fixture for radiator core welding

Abstract

The invention provides a constraint fixture for radiator core welding. The constraint fixture comprises a body, a left clamping part and a right clamping part, wherein the left clamping part is arranged at the left end of the body; the right clamping part is arranged at the right end of the body; the body comprises a first transverse rod and a second transverse rod; the length of the first transverse rod is equal to that of the second transverse rod; the left clamping part connects the left end of the first transverse rod with the left end of the second transverse rod; the right clamping part connects the right end of the first transverse rod with the right end of the second transverse rod; a trapezoidal groove is formed in each of two ends of the first transverse rod and each of two ends of the second transverse rod; the distance between each trapezoidal groove and the corresponding end is 17.3mm, and the width of each trapezoidal groove is 5.2mm; sixty-six circular-arc-shaped grooves are uniformly formed in the middle parts of the first transverse rod and the second transverse rod and are formed between the trapezoidal grooves in the two ends; the spacing between every two adjacent circular-arc-shaped grooves is 8.2mm, and the diameter of each circular-arc-shaped groove is 3.5mm. The constraint fixture has the beneficial effects that a radiator core can be clamped by using the constraint fixture, and certain distance between the constraint fixture and a radiating pipe can be kept after the clamping by the constraint fixture.

Description

technical field [0001] The invention relates to an auxiliary equipment required for heat-welding of radiator cores, in particular to a restraint jig used for heat-welding of 16 radiator cores. Background technique [0002] The restraint jig used for heat sink soldering is used to clamp the radiator core during assembly and soldering, so that the position accuracy relative to the core assembly machine is guaranteed by the jig, so as to ensure the The radiator core is not affected by the technical level of workers, so that the processing accuracy of the products tends to be consistent. The restraining jig for radiator cores is mainly used in the assembly and baking processes in the manufacturing process of radiator cores. The restraint fixture used for the radiator core is designed to ensure the technical requirements of the process involved, focusing on ensuring the product assembly size and baking quality; the assembly size mainly refers to the distance between the two guar...

Problems solved by technology

[0003] In the prior art, although the processing accuracy requirements of the product can be guaranteed in the product assembly process, in the subsequent baking and welding process, because workers often fail to adjust the restraint fixture in place (keep a certain distance from the heat dissipation pipe), under high temperature ( 625℃) baked and welded, resulting in contact between the restraint fixture and the heat dissipation pipe, resulting in perforation of the heat dissipation pipe or corrosion of the heat dissipation belt, resulting in defective scrapping
