Description

Technical Field

[0001] This utility model relates to the field of copper pipe welding technology, and in particular to a copper liquid collection pipe welding station. Background Technology

[0002] Copper manifolds are copper pipe fittings used in refrigeration systems to collect and distribute liquid refrigerant. They are typically made of a main pipe welded together with multiple reducing branch pipes. Their core function is to distribute the liquid refrigerant returning from the evaporator evenly to each heat exchange branch through a reducing flow design, thus avoiding the risk of liquid slugging in the compressor. At the same time, the high thermal conductivity of copper pipes helps to vaporize residual refrigerant.

[0003] The existing copper manifold includes a main pipe and several branch pipes perpendicular to it. These branch pipes are fixed to the main pipe by welding. During welding, the main pipe and branch pipes of the manifold are quickly fixed in place by a copper manifold welding station and welded by a welding torch.

[0004] However, in existing copper manifold welding stations, the clamps hold the branch pipes, and the alignment of the branch pipes with the main pipe often relies on manual visual positioning, requiring repeated movement of the branch pipe clamps to adjust their positions, which is quite cumbersome. Furthermore, after the main pipe and one side of the manifold are welded together, it needs to be flipped over and the other side welded. The manifold that has just been welded has a high temperature, and it takes a long time to cool down naturally. Therefore, this application proposes a copper manifold welding station. Utility Model Content

A second electric push rod is fixedly installed on the outer side of each side plate, and a branch pipe clamping plate is fixedly installed at one end of each second electric push rod.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] This utility model provides a technical solution: such as Figure 1-4 As shown, the copper manifold welding station includes a workstation 1. Both inner sides of the workstation 1 are fixedly installed with drive seats 2. Each drive seat 2 is slidably connected with a moving block 7. Two sliding rods 5 are installed between the two moving blocks 7. One of the drive seats 2 is equipped with a moving mechanism, which drives the moving block 7 to slide. The two sliding rods 5 are slidably connected with multiple assembly seats 15. Each assembly seat 15 is equipped with quick clamps 17 on both outer sides. The quick clamps 17 can realize the clamping and limiting between the assembly seat 15 and the sliding rod 5. The quick clamps 17 are existing technology and will not be described in detail here.

[0023] Each assembly base 15 has a branch pipe placement base 18 fixedly installed on its top surface, and a branch pipe clamping mechanism on its top surface. Two laser emitters 24 are symmetrically installed at one end of each assembly base 15. Inclined plates 22 are fixedly installed on both outer sides of each assembly base 15, and a cooling fan 23 is fixedly installed on the outer side of each inclined plate 22. A main pipe clamping mechanism is provided on the outer side of each of the two drive bases 2. The laser emitters 24, which are symmetrically installed at a 15-degree angle, project a fan-shaped crosshair, forming a positioning area on the outer side of the main pipe. This area can be used to assist operators in aligning the welding position of the branch pipe with that of the main pipe. Furthermore, the cooling fans 23 installed at an incline on both sides can achieve a double spiral airflow field, which can target the weld seam for cooling, thereby quickly cooling the weld seam and improving work efficiency.

[0024] Furthermore, the moving mechanism includes a threaded rod 6, which is rotatably connected to a corresponding drive seat 2 and threadedly connected to a corresponding moving block 7. A guide rod 9 is fixedly installed in another drive seat 2 and slidably connected to the corresponding moving block 7. A drive motor 8 is fixedly installed on the outside of one of the drive seats 2, and the output shaft of the drive motor 8 is connected to one end of the threaded rod 6. The drive motor 8 can be a conical rotor motor, whose output shaft locks when de-energized, thereby ensuring the limiting of the moving block 7. At the same time, the guide rod 9 can provide guidance and limiting functions for the other moving block 7.

[0025] Furthermore, each branch pipe clamping mechanism includes two side plates 19, and both side plates 19 are fixedly installed on the two outer sides of the mounting base 15. A second electric push rod 20 is fixedly installed on the outer side of each side plate 19, and a branch pipe clamping plate 21 is fixedly installed at one end of each second electric push rod 20.

[0026] Furthermore, each main pipe clamping mechanism includes a fixed base 10, a main pipe placement base 14 is fixedly installed on the top surface of each fixed base 10, an L-shaped fixing plate 11 is fixedly installed on the top surface of each fixed base 10, a first electric push rod 12 is fixedly installed on the top surface of each L-shaped fixing plate 11, and a main pipe clamping plate 13 is installed at the bottom end of each first electric push rod 12.

[0027] Furthermore, an electric guide rail 3 is fixedly installed on the top surface of workstation 1. A welding gun robot 4 is slidably connected to the top surface of the electric guide rail 3. The welding gun robot 4 can slide linearly back and forth through the electric guide rail 3. The electric guide rail 3 has a limit locking function, which is a mature existing technology and will not be described in detail here.

[0028] Furthermore, each main pipe clamping plate 13 and branch pipe clamping plate 21 is made of rubber, and each mounting base 15 has a handle 16 fixedly installed on its outer side.

[0029] This utility model provides a copper manifold welding station. The specific working principle is as follows: When the operator is using it, first place the main pipe on the top surface of the two main pipe placement seats 14, then start the first electric push rod 12 to drive the main pipe clamping plate 13 to slide downward, thereby clamping the main pipe. Then, each branch pipe can be placed on the top surface of the branch pipe placement seat 18, and start the second electric push rod 20 installed on both sides to drive the branch pipe clamping plate 21 to clamp and limit the branch pipe.

[0030] Next, the two laser emitters 24 symmetrically installed on the outside of each mounting base 15 can be activated to project a fan-shaped crosshair onto the main pipe. Then, the operator can release the limit between the mounting base 15 and the slide bar 5 through the quick clamp 17 and freely slide the mounting base 15. When the center point of the fan-shaped crosshair corresponds to the welding position of the main pipe, stop the sliding of the mounting base 15 and limit the mounting base 15 again through the quick clamp 17. Through the above operation, each branch pipe can be aligned with the position of the main pipe.

[0031] Next, the drive motor 8 is started to drive the threaded rod 6 to rotate, thereby driving the moving block 7 to slide. The two sliding rods 5 pull another moving block 7 to slide synchronously, so that the branch pipe held on the top surface of each assembly seat 15 moves and abuts against the main pipe. At this time, the electric guide rail 3 can be started to drive the welding gun robot 4 to slide, and the welding gun on the welding gun robot 4 can weld the branch pipe and the main pipe. After each branch pipe is welded, the two cooling fans 23 installed at an angle on the outside of each assembly seat 15 can be started to quickly dissipate heat from the weld, thereby quickly cooling the liquid collection pipe. Then, the limits on the main pipe and branch pipe are released respectively, and they are flipped and re-limited, so that the other side of the liquid collection pipe can be welded.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
