Description

Technical Field

[0001] This utility model relates to the field of radiator welding technology, specifically a welding equipment for the overlapping production of steel radiators. Background Technology

[0002] Overlapping radiators are constructed by welding fixed pipes and fins. A search revealed a utility model patent with publication number CN101592446A, which discloses a single-overlapping radiator. Its features include: a single-overlapping radiator branch pipe installed on one side of the upper and lower connecting pipes; the water distribution holes of the upper and lower connecting pipes have outward-facing flanges forming annular bosses; these annular bosses are embedded in the water passages of the radiator branch pipe and welded together with it. The manufacturing method of the single-overlapping radiator includes processes such as material preparation, shaping, overlapping welding, anti-corrosion treatment, spraying, and drying.

[0003] The existing welding equipment used for producing steel radiators has a relatively fixed position for welding pipes and fins. If misalignment occurs, it will directly affect the quality of the radiator. Utility Model Content

[0004] The purpose of this utility model is to provide a welding equipment for the overlapping production of steel radiators, which solves the problem that when existing welding equipment for overlapping production of steel radiators is used, misalignment due to the relatively fixed position of the fixed pipe and fin welding will directly affect the quality of the radiator.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a welding equipment for the overlapping production of steel radiators, comprising a tooling base, two support seats slidably connected to the upper end of the tooling base, each support seat having a fixed pipe placed on it, multiple fins welded above the fixed pipe, an adjustment mechanism provided on the support seat, a slide seat fixedly connected to the bottom of the support seat, the slide seat penetrating the tooling base and slidably connected to it, an adjustment plate fixedly connected to the bottom of the slide seat, a fixed plate fixedly connected to the bottom left side of the tooling base, a motor fixedly mounted on the fixed plate, a bidirectional screw fixedly connected to the end of the output shaft of the motor, the bidirectional screw penetrating the fixed plate and being threadedly connected to the fixed plate, a bracket fixedly connected to the upper right side of the tooling base, and a welding head clamped to the horizontal part of the bracket.

[0006] Preferably, a limiting ring is fixedly connected to the slide, and the limiting ring contacts the bottom of the tooling base. The limiting ring provides a limiting function for the vertical direction of the slide.

[0007] Preferably, a support plate is fixedly connected to the bottom right side of the tooling base, and the bidirectional screw is connected to the support plate via a bearing. The support plate provides auxiliary support for the bidirectional screw.

[0008] Preferably, the adjusting mechanism includes a hollow shell fixedly connected to the side of the support base. Two sliding plates are slidably connected to the side wall of the hollow shell, and the sliding plates penetrate the hollow shell. The sliding plates abut against the fins. An adjusting rod is threadedly connected to the top of the hollow shell, and a push block is mounted on the end of the adjusting rod via a bearing. The push block abuts against the sliding plates. The adjusting mechanism effectively limits the welding distance between the fins.

[0009] Preferably, the push block has ball bearings on its side, and these ball bearings contact the inner surface of the hollow shell. The ball bearings reduce the relative friction between the push block and the hollow shell.

[0010] Preferably, a guide rod is fixedly connected to the top inner side of the hollow shell, and the guide rod is slidably connected to the push block. The guide rod guides the lifting and lowering of the push block.

[0011] Preferably, each slider is fixedly connected to a slider at its bottom, and a fixing rod is fixedly connected to the lower inner side of the hollow shell. The fixing rod passes through the slider and is slidably connected to it. A spring is fixedly connected to the middle section of the fixing rod, and the two ends of the spring are fixedly connected to the two sliders respectively. The arrangement of the slider, fixing rod, and spring provides an auxiliary resetting function for the slider.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides a support base on the tooling base that is driven to move laterally by a motor and a bidirectional screw. The spacing between the support bases can be controlled by adjusting the threaded movement between the adjustment plate and the bidirectional screw. This makes it applicable to the welding spacing of the fixed pipes of steel radiators, thus improving the overall applicability.

[0014] 2. This utility model provides an adjusting mechanism on the support base, located between the fins of the steel radiator. By rotating the adjusting rod, the adjusting rod moves threadedly with the hollow shell, controlling the lifting and lowering of the push block. This allows the push block to control the extension of the sliding fins within the hollow shell, thus adjusting and fixing the spacing between the fins of the steel radiator and ensuring the quality of the steel radiator welding.

A bracket 12 is fixedly connected to the upper right side of the fixture base 1. A welding head 13 is clamped to the horizontal part of the bracket 12.

[0024] Please see Figures 4-5 The support base 2 is equipped with an adjusting mechanism 3, which limits the welding distance between the fins 5. The adjusting mechanism 3 includes a hollow shell 31 fixedly connected to the side of the support base 2. Two sliding plates 32 are slidably connected to the side wall of the hollow shell 31, and the sliding plates 32 penetrate the hollow shell 31 and abut against the fins 5. An adjusting rod 36 is threadedly connected to the top of the hollow shell 31, and a push block 37 is mounted on the end of the adjusting rod 36 via a bearing. The push block 37 abuts against the sliding plates 32. A ball bearing 39 is provided on the side of the push block 37, and the ball bearing 39 contacts the inner surface of the hollow shell 31.

[0025] The specific implementation process of this utility model is as follows: In use, firstly, place the two fixed pipes 4 of the steel radiator on the support base 2. Then, adjust the position of the two support bases 2 according to the required spacing of the fixed pipes 4. This can be achieved by driving the bidirectional screw 10 to rotate via the motor 9. The two adjusting plates 7 on the bidirectional screw 10 can move towards or away from each other, thereby controlling the spacing of the support bases 2. Subsequently, place the fins 5 above the fixed pipes 4. By rotating the adjusting rod 36, the adjusting rod 36 can control the lifting and lowering of the push block 37 through the threaded movement between it and the hollow shell 31. This allows the push block 37 to control the extension of the sliding plate 32 within the hollow shell 31, thus adjusting and fixing the spacing between the fins 5 of the steel radiator and ensuring the quality of the steel radiator welding. Finally, remove the welding head 13 and weld the connection between the fins 5 and the fixed pipes 4.
