[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0038] Embodiment 1:

[0039] This embodiment provides a copper filter positioning tool, which is used to mechanically position the copper filter 1 when welding the pipeline 2 on the copper filter 1. The positioning tool includes a column 3 and a frame. A straight groove 31 is provided on the end surface of one end of the column 3. Preferably, the straight groove 31 is a round groove. Of course, the straight groove 31 can also be a square groove. A round hole 32 is provided at the center of the bottom of the straight groove 31. The round hole 32 is a straight hole. The copper filter 1 has a middle section and connecting pipes at both ends of the middle section. The middle section and the connecting pipe are both round pipes, and the pipe diameter of the middle section is larger than the pipe diameter of the connecting pipe.

[0040] When in use, the copper filter 1 is inserted into the above-mentioned straight groove 31, and the connecting pipe at one end of the copper filter 1 is inserted into the above-mentioned circular hole 32. The diameter of the above-mentioned straight groove 31 is adapted to the outer diameter of the middle section of the copper filter 1, and the aperture of the above-mentioned circular hole 32 is adapted to the outer diameter of the connecting pipe at the end of the copper filter 1.

[0041] Through the above-mentioned method, the interaction between the hole wall of the circular hole 32 and the outer wall of the connecting pipe at the end of the copper filter 1 can radially position the copper filter 1. The interaction between the groove wall of the straight groove 31 and the outer wall of the middle section of the copper filter 1 can also radially position the copper filter 1. The interaction between the hole edge of the circular hole 32 and the outer wall of the copper filter 1 can axially position the copper filter 1. Therefore, the column 3 using the above-mentioned structure can axially and radially position the copper filter 1, and it is mechanical positioning.

[0042] The column 3 is detachably fixed to the frame. When the copper filter 1 is installed on the column 3, its spatial position will be fixed. When the pipeline 2 is welded thereon, no shaking or deviation will occur. Therefore, the welding is more stable and reliable, reducing the probability of product scrapping and improving processing efficiency.

[0043] Embodiment 2:

[0044] This embodiment is further improved on the basis of embodiment 1. In this embodiment, a first hole 33 is provided on the side wall of the above-mentioned column 3, and the first hole 33 is connected to the above-mentioned circular hole 32, and a connector 7 for connecting an air pipe is installed at the first hole 33 for connecting the air pipe for introducing protective gas.

[0045] Specifically, the first hole 33 is opened at a suitable position of the above-mentioned circular hole 32, so that when the copper filter 1 is installed on the column 3, the first hole 33 is located below the copper filter 1, so that the protective gas entering from the first hole 33 will flow into the interior of the copper filter 1. With this structure, when the pipeline 2 is welded on the copper filter 1, the protective gas is introduced, and the protective gas will fill the copper filter 1 and the pipeline 2, thereby protecting the welding point, isolating the inner wall at the welding point from the air, thereby preventing the inner wall at the welding point from oxidation corrosion, and thus extending the life of the welding point.

[0046] As an optimal implementation manner of this embodiment, the above-mentioned protective gas is nitrogen.

[0047] Embodiment 3:

[0048] This embodiment is further improved on the basis of the above embodiment. In this embodiment, a chamfer 8 is provided on the side wall of the slot of the straight slot 31 and / or the edge of the circular hole 32. Optimally, a chamfer 8 is provided on the side wall of the slot of the straight slot 31 and the edge of the circular hole 32. The chamfer 8 is also a slope.

[0049] The above structure facilitates the copper filter 1 to be inserted into the straight groove 31 and the circular hole 32, and the chamfer 8 of the edge of the circular hole 32 can cooperate with the outer wall of the copper filter 1 to achieve a better positioning effect.

[0050] Embodiment 4:

[0051] This embodiment is further improved on the basis of the above embodiment. In this embodiment, a notch 34 is provided on the wall of the straight groove 31. The notch 34 is directly opposite to the bottom of the straight groove 31, and the notch 34 penetrates the wall of the straight groove 31. With this structure, the user can observe whether the copper filter 1 is installed properly through the notch 34. If the copper filter 1 is not installed properly, a tool can be used to temporarily revise it from the notch 34, so as to ensure that the copper filter 1 can meet the fixing requirements. In fact, the notch 34 is an observation and inspection port.

[0052] Embodiment 5:
