Description

Technical Field

[0001] The invention relates to the technical field of brazing, and in particular to a high-precision radiator brazing tool. Background Art

[0002] The car radiator includes a core and water chambers on both sides of the core. The core is welded by a water pipe, a main plate and a heat dissipation belt. Before welding the core, the core needs to be plugged and assembled. After the assembly is completed, the two sides of the core are clamped and positioned by a brazing tool. Brazing refers to a welding method in which the brazing material below the melting point of the weldment and the weldment are heated to the melting temperature of the brazing material at the same time, and the gap between the solid workpieces is filled with liquid brazing material to connect the metals. When brazing the core, the core is generally clamped and fixed by a tool to facilitate the brazing of the core.

[0003] Conventional brazing tooling in the prior art can currently ensure the following shape errors: 1) the radiator diagonal error is more than 1 mm; 2) the radiator height error is more than 1 mm; 3) the radiator length error is more than 1 mm.

[0004] The above are only the appearance errors that can be directly detected after the radiator brazing is completed. The radiator brazed by conventional tooling has certain rules: First, the radiator has a relatively regular appearance, usually a three-dimensional regular structure composed of six planes, so the usage of conventional assembly tooling is relatively simple, and conventional brazing tooling has the following problems: 1) The accuracy is not high; 2) It cannot meet the assembly requirements of radiators with special-shaped structures; 3) It cannot meet the mass production brazing requirements of radiators with high precision requirements;

[0005] Therefore, when the actual production of high-precision mass production brazing tooling requires irregular shapes, high tooling flatness and verticality errors, and upper and lower plane parallelism and other technical indicators, the current conventional radiator brazing tooling is unable to meet and achieve its high technical requirements.

[0006] In view of this, the high-precision heat sink brazing tooling that can be mass-produced still needs to be further improved. Summary of the invention

The C-type clamp 330 is arranged corresponding to the fixing seat 310. The C-type clamp 330 is fixed to the fixing seat 310 by the cooperation of the pin 331 and the pin hole 311, and the pressing plate 320, the flow channel 500 and the fixing seat 310 are clamped to clamp the flow channel 500 between the fixing seat 310 and the pressing plate 320, so as to realize the positioning and fixing of the flow channel 500 in the vertical direction.

[0048] In one embodiment, the top surfaces of several of the fixing seats 310 and the top surface of the fixing block 221 are located in the same plane, and the flow channel 500 is placed on the top surfaces of the fixing seat 310 and the fixing block 221 relative to a side of the support assembly 100 to ensure that the flow channel 500 matches the faucet 400 in the vertical direction.

[0052] The following is a description of a high-precision heat sink brazing tool in one embodiment of the present invention with reference to the accompanying drawings.

[0053] like Figure 1 As shown, the high-precision radiator brazing fixture includes a support component 100, a positioning component 200 and a fixing component 300. By respectively arranging the fixing component 300 and the positioning component 200 on the brazing fixture, the positioning component 200 realizes the matching of the water nozzle 400 and the flow channel 500 in the horizontal direction, and then the fixing component 300 realizes the matching of the water nozzle 400 and the flow channel 500 in the vertical direction. Therefore, when the water nozzle and the flow channel in the radiator are irregular shapes, the position accuracy between the water nozzle and the flow channel during the welding process can still be guaranteed. After the positioning and clamping of each component of the product, a radiator that meets the high dimensional accuracy requirements can be welded. Specifically, the flatness of the flow channel can meet the requirement of not more than 0.2mm, and the distance tolerance between the flow channel and the water nozzle can meet the requirement of 0-0.3mm.

[0054] From a process perspective, the high-precision radiator brazing tooling needs to arrange regular (one month) re-measurement of dimensions to prevent deformation caused by long-term thermal expansion and contraction in the chain furnace. The corresponding components can be reworked after mechanical processing to ensure the consistency of the welded radiator products and meet the relevant requirements of existing radiator products for high-precision technical indicators such as flatness, verticality, parallelism and coplanarity, namely: 1) The radiator diagonal error is less than 1mm; 2) The radiator height error is less than 1mm; 3) The radiator length error is less than 1mm; at the same time, the high-precision radiator brazing tooling only needs one welding process to obtain the radiator product, which greatly simplifies the existing process flow and reduces production costs.

[0055] In this embodiment, the positioning component 200 and the fixing component 300 are fixed to the support component 100 by positioning welding, and after the welding process, the high-precision radiator brazing tooling is placed in a brazing furnace for heat treatment at 600°C for 12 hours to ensure subsequent processing accuracy.

[0056] Furthermore, if Figure 4 As shown, a graphite pad 110 is provided on the support assembly 100 to provide a heat conduction function for the water nozzle 400 and the flow channel 500 during the brazing process to avoid heat accumulation affecting the processing accuracy.

[0057] Furthermore, if Figure 1 and Figure 3 As shown, the positioning assembly 200 is fixedly mounted on the support assembly 100, wherein the positioning assembly 200 includes a faucet clamp 210 corresponding to the faucet 400 and a flow channel clamp 220 corresponding to the flow channel 500. Figure 3 and Figure 4 As shown, the faucet clamp 210 includes a fixed plate 211, a movable plate 212 and a movable pin 213, wherein the fixed plate 211 is vertically fixed on the support assembly 100, and the movable plate 212 can be moved relative to the fixed plate 211 through the movable pin 213 to adjust the distance between the movable plate 212 and the fixed plate 211, thereby clamping and fixing the faucet 400, ensuring the position of the faucet 400 in the horizontal direction, and ensuring the matching accuracy between the faucet 400 and the flow channel 500 in the horizontal plane.

[0058] Further, the flow channel clamp 220 includes a fixed block 221, a clamping block 222 and a push rod 223, wherein the fixed block 221 and the clamping block 222 are both arranged in a long strip shape to correspond to the two opposite sides of the flow channel 500. The fixed block 221 is fixed to the support assembly 100, and the clamping block 222 can move relative to the fixed block 221 along the support assembly 100 to adjust the distance between the fixed block 221 and the clamping block 222, so as to clamp and fix the flow channel 500. Specifically, the fixed block 221 and the clamping block 222 are arranged in parallel to achieve stable clamping of the flow channel 500. Furthermore, the push rod 223 is provided on the side of the clamping block 222 away from the fixing block 221, and three push rods 223 are provided in parallel, corresponding to the two ends and the middle position of the clamping block 222 respectively, and the distance between the clamping block 222 and the fixing block 221 is adjusted by the push rod 223 to achieve the clamping and fixing of the flow channel 500. Specifically, the posture of the clamping block 222 is adjusted by the three push rods 223 to match the corresponding flow channel shape, thereby achieving stable clamping of the flow channel 500, ensuring the position of the flow channel 500 in the horizontal direction, and ensuring the matching accuracy between the flow channel 500 and the faucet 400 on the horizontal plane.

[0059] Furthermore, if Figure 1 and Figure 3 As shown, the fixing assembly 300 is fixed on the surface of the supporting assembly 100 and is arranged corresponding to the flow channel 500. Specifically, the fixing assembly 300 includes a fixing seat 310, a pressing plate 320 and a C-type clamp 330 to cooperate to achieve clamping and fixing of the flow channel 500. Figure 2 and Figure 3 As shown, there are four fixing seats 310, and the fixing seats 310 are symmetrically arranged on both sides of the flow channel 500 in groups of two, and a horizontal plane is formed by matching the four fixing seats 310 and the fixing block 221 to ensure the height of the flow channel 500 in the vertical direction. Specifically, the top surfaces of the four fixing seats 310 and the top surface of the fixing block 221 are at the same height and fall on the same plane, and the heights of the fixing seats 310 and the fixing block 221 match the height setting of the water nozzle 400, so as to ensure that after the flow channel 500 is placed on the fixing seats 310 and the fixing block 221, the flow channel 500 matches the height setting of the water nozzle 400, ensuring the matching accuracy of the flow channel 500 and the water nozzle 400 in the vertical direction, thereby ensuring the accuracy of the final brazing effect.

[0060] Furthermore, if Figure 1 and Figure 2As shown, a pin hole 311 is provided on the top surface of the fixing seat 310, and the C-type clamp 330 is fixed to the fixing seat 310 by the pin 331 cooperating with the pin hole 311. Further, the C-type clamp 330 clamps the pressing plate 320 and the flow channel 500, and the pin 331 passes through both ends of the C-type clamp 330 to fix the pressing plate 320 and the flow channel 500 to the fixing seat 310, thereby ensuring the flatness of the flow channel 500 and the processing accuracy of the flow channel 500 and the faucet 400 during the brazing process.

[0061] Specifically, Figure 3 and Figure 4 As shown, the pressing plate 320 includes a graphite pressing block 321 and a stainless steel pressing plate 322, wherein the graphite pressing block 321 is placed on the flow channel 500, and the stainless steel pressing plate 322 is arranged on the graphite pressing block 321, and the pin 331 passes through the stainless steel pressing plate 322 to fix the graphite pressing block 321 and the flow channel 500 in the C-type clamp 330 and clamp them, thereby ensuring the flatness of the flow channel 500.

[0062] Specifically, through the arrangement of the fixing assembly 300 and the positioning assembly 200, the high-precision radiator brazing fixture in this embodiment can achieve a flatness of less than 0.2 mm and a distance tolerance of 0-0.3 mm between the nozzle and the flow channel. Compared with the existing radiator brazing fixture, the addition of heat treatment can effectively ensure the reliability of the stainless steel bracket and enhance the performance characteristics of the material, and can also ensure that the fixture does not deform or slightly deforms after multiple brazings, so as not to affect the precision requirements of the finished product after brazing.

[0063] The present invention provides a high-precision radiator brazing tool. The stainless steel pipe is positioned by the tool and then welded. The stainless steel frame is heat-treated to enhance the material strength and reduce the deformation caused by thermal expansion and contraction. The position accuracy is ensured by machining. After the various components of the product are positioned and clamped, a brazing quality that meets the high dimensional accuracy requirements of the product can be welded.

[0064] The high-precision radiator brazing tooling provided by the present invention will undergo deformation due to thermal expansion and contraction in the furnace for a long time, so it is necessary to remeasure the dimensions once a month. After machining and reworking the corresponding parts, the consistency of the welded products can be guaranteed, meeting the high-precision technical indicators requirements of the entire product for flatness, verticality, parallelism, coplanarity, etc.

[0065] In summary, the present invention discloses a high-precision radiator brazing tool, the radiator includes a water nozzle and a flow channel fixed by brazing, wherein the high-precision radiator brazing tool includes a supporting component, a fixing component and a positioning component, the fixing component and the positioning component are fixed on the supporting component; wherein the water nozzle and the flow channel are clamped on the positioning component to achieve the matching of the water nozzle and the flow channel in the horizontal direction, and the fixing component cooperates with the supporting component to fix the water nozzle and the flow channel on the supporting component to achieve the matching of the water nozzle and the flow channel in the vertical direction. By respectively arranging the fixing component and the positioning component on the brazing tool, the matching of the water nozzle and the flow channel in the horizontal direction is achieved by the positioning component, and then the matching of the water nozzle and the flow channel in the vertical direction is achieved by the fixing component, so that when the water nozzle and the flow channel are irregular shapes, the position accuracy between the water nozzle and the flow channel during the welding process can still be guaranteed, and after the positioning and clamping of the various components of the product, a radiator that meets the high dimensional accuracy requirements can be welded.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
