[0002] The air conditioner stop valve is an important component of a split air conditioner, which plays the role of connecting, closing or opening the refrigerant circuit between the outdoor unit and the indoor unit, and evacuating or charging the refrigerant. When in use, the stop valve usually needs to be welded with various connecting pipes for assembly. At present, the common method is to manually weld each connecting pipe to the stop valve with a welding torch, resulting in low work efficiency.
[0003] Therefore, how to provide a welding tool for an air conditioner stop valve is the research purpose of the present utility model. Summary of the Utility Model
[0004] In view of the above deficiencies in the technology, the present utility model provides a welding tool for an air conditioner stop valve. By using multiple groups of welding tools to fixedly support multiple groups of stop valves and their connecting pipes, and cooperating with a welding manipulator, multiple groups of stop valves can be welded simultaneously, improving the welding efficiency; moreover, the fixed base and the adjusting block of each group of welding tools are of a split structure, which can fixedly support stop valves of various different specifications without replacing the entire welding tool.

[0006] A welding tool for an air conditioner stop valve, characterized in that: it includes a bottom plate, and one or more groups of welding tools are provided on the bottom plate. A pipe support rod is provided on one side of each group of welding tools. Each group of welding tools includes a fixed base and an adjusting block. The fixed base is arranged in a groove structure with an open top, a guide sleeve is provided inside it, and a water baffle is provided at the front end. The adjusting block is installed at the top of the fixed base through bolts. L-shaped limiting structures are provided at both ends of the adjusting block, and the limiting structures are located on both sides of the guide sleeve. The pipe support rod is installed on the bottom plate through a rotating shaft, and the pipe support rod and the rotating shaft are connected through a movable hinge.
[0007] Further, a groove structure for supporting the connecting pipe is provided at the top of the pipe support rod.
[0008] Further, the water baffle is rotatably arranged at the front end of the fixed base through a guide rod, and both ends of the guide rod are rotatably arranged above the bottom plate through guide blocks.
[0009] Further, one or more groups of elastic reset mechanisms are also provided on the guide rod. Each group of elastic reset mechanisms includes a torsion spring fixedly arranged outside the guide rod, and compression spring blocks are respectively provided at both ends of the torsion spring.
[0010] The beneficial effects of the present utility model are as follows: 1. By using multiple groups of welding fixtures to fixedly support multiple groups of stop valves and their connecting pipes, and cooperating with a welding manipulator, multiple groups of stop valves can be welded simultaneously, improving the welding efficiency; 2. The fixed base and the adjusting block of each group of welding fixtures are of a split structure, which can fixedly support stop valves of various different specifications without replacing the entire welding fixture, saving time; 3. The pipe support rod and the rotating shaft are combined by hinges, fixing the orientation required for the stop valve piping and ensuring the accuracy and consistency of welding; 4. Before welding, the fixed base and the water baffle are fitted together to form a water basin with good sealing performance. The water inlet connected to the fixed base is filled with water to protect the stop valve. After welding is completed, the water baffle is rotated by driving the guide rod, and the water baffle is not in contact with the fixed base, and all the water flows away, thus facilitating the removal of the welded stop valve assembly.

Detailed Embodiment
[0019] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the following is a further analysis of the present utility model in conjunction with the attached Figure 1-7 drawings.
[0020] As Figure 1-7As shown in the figure, a welding tooling for an air-conditioning stop valve is characterized in that it includes a bottom plate 1, and one or more groups of welding toolings 2 are arranged on the bottom plate 1. On one side of each group of welding toolings 2, there are respectively arranged pipe support rods 3. Each group of welding toolings 2 includes a fixed base 201 and an adjusting block 202. The fixed base 201 is arranged in a groove structure with an open top. A guide sleeve 203 is arranged inside it, and a water baffle 204 is arranged at the front end. The adjusting block 202 is installed at the top of the fixed base 201 through bolts. At both ends of the adjusting block 202, there are L-shaped limiting structures 202a, and the limiting structures 202a are located on both sides of the guide sleeve 203. The pipe support rod 3 is installed on the bottom plate 1 through a rotating shaft 4, and the pipe support rod 3 and the rotating shaft 4 are connected through a movable hinge 5. The position of the pipe support rod 3 can be adjusted through the movable hinge 5 so as to support the stop valve pipe.
[0021] In this embodiment, preferably, a groove structure 3a for supporting the connecting pipe is arranged at the top of the pipe support rod 3.
[0022] In this embodiment, preferably, the water baffle 204 is rotatably arranged at the front end of the fixed base 201 through a guide rod 6, and both ends of the guide rod 6 are rotatably arranged above the bottom plate 1 through guide blocks.
[0023] In this embodiment, preferably, one or more groups of elastic reset mechanisms 7 are also arranged on the guide rod 6. Each group of elastic reset mechanisms 7 includes a torsion spring 701 fixedly arranged outside the guide rod 6. At both ends of the torsion spring 701, there are respectively arranged compression spring blocks 702. After rotating the guide rod 6, when there is no force applied, the torsion spring 701 drives the guide rod 6 to rebound and reset, so that the water baffle 204 rebounds and resets.
[0024] The working principle of the present utility model: Place the stop valve into the guide sleeve 203, longitudinally clamp both sides of the stop valve through the limiting structure 202a of the adjusting block 202 for fixed positioning. Arrange the pipes to be welded of the stop valve well, support the end of the stop valve pipe through the pipe support rod 3, and ensure the precise installation and positioning of the stop valve. Before welding, the fixed base 201 of the stop valve and the water baffle 204 are attached to form a water basin with good sealing performance. The water inlet of the fixed base 201 is filled with water to protect the stop valve. After welding, rotate the guide rod 6 to drive the water baffle 204 to rotate. The water baffle 204 is not attached to the fixed base, and all the water flows away, so as to facilitate taking away the welded stop valve assembly.
