[0041] With reference to Figure 1 and Figure 2 , according to the first aspect of the embodiments of the present application, the welding jig is used for mounting a first pipe 110 and a second pipe 120, the first pipe 110 comprises a first end 111 and a second end 112, the second pipe 120 comprises a third end 121 and a fourth end 122, the second end 112 is in contact with the third end 121, and the welding jig comprises a base 200 and a limiting piece 320. The base 200 is provided with a connecting part 210, the connecting part 210 is used for limiting the first end 111 at a first set position. The limiting piece 320 is located above the base 200, the limiting piece 320 is connected with the base 200, and the limiting piece 320 is used for limiting the fourth end 122 at a second set position.

[0042] According to the welding jig of the embodiments of the present application, at least the following beneficial effects are achieved: the first end 111 of the first pipe 110 (for example, a copper pipe) is limited at the first set position by the connecting part 210, and the fourth end 122 of the second pipe 120 (for example, another copper pipe) is limited at the second set position by the limiting piece 320, so that the installation of the first pipe 110 and the second pipe 120 can be completed, and the installation is convenient and fast.

[0043] Specifically, the base 200 and the limiting piece 320 are both mounted on the box body 600.

[0044] With reference to Figure 2 In some embodiments of the present application, the connecting part 210 is in plug-in cooperation with the first end 111.

[0045] The connecting part 210 is in plug-in cooperation with the first end 111, and the installation is simple and fast, thereby facilitating the fast limitation of the first end 111 at the first set position.

[0046] In another embodiment, the connecting part 210 can also clamp the first end 111, so as to limit the first end 111 at the first set position. For example, the connecting part 210 comprises a pipe clamp, which clamps or releases the first end 111.

[0047] With reference to Figure 2In the improved scheme of the above embodiment, the connecting portion 210 comprises a boss 211, which is inserted into the first end 111.

[0048] By inserting the boss 211 into the hole of the first end 111, the plug-in cooperation can be quickly realized. The boss 211 is simple to manufacture, thereby facilitating the reduction of the production cost of the base 200.

[0049] Referring to Figure 3 In the improved scheme of the above embodiment, the connecting portion 210 comprises a mounting hole 212, and the first end 111 is inserted into the mounting hole 212.

[0050] By inserting the first end 111 into the mounting hole 212, the plug-in cooperation can be quickly realized. The mounting hole 212 is simple to manufacture, thereby facilitating the reduction of the production cost of the base 200.

[0051] Referring to Figure 2 In some embodiments of the present application, the boss 211 is provided with two or more than two, and the outer diameters of any two bosses 211 are different.

[0052] By providing two or more than two bosses 211 with different outer diameters, the base 200 can be plugged into the first pipe 110 with different pipe diameters, and the compatibility of the welding jig is stronger.

[0053] Referring to Figure 2 In the improved scheme of the above embodiment, the direction in which the boss 211 faces the limiting piece 320 is the first direction (see Figure 2 , for example, the first direction is the upward direction), the bosses 211 are stacked along the first direction, and the outer diameters of the bosses 211 gradually decrease along the first direction.

[0054] By stacking the bosses 211 together along the first direction, it is beneficial to make the first pipe 110 installed on the base 200 in a relatively fixed position, thereby facilitating the welding of the first pipe 110 and the second pipe 120.

[0055] It should be noted that the outer diameters of the bosses 211 gradually decrease along the first direction, so that each boss 211 can be inserted into the first pipe 110 with the corresponding pipe diameter without hindrance. For example, if a boss 211 with a larger outer diameter is located above another boss 211 with a smaller outer diameter, the boss 211 with the larger outer diameter will hinder the first pipe 110 with the corresponding pipe diameter from being plugged into the boss 211 with the smaller outer diameter.

[0056] Referring to Figure 2 In the improved scheme of the above embodiment, the boss 211 is provided with an exhaust hole 220, and the exhaust hole 220 is used to introduce protective gas into the first end 111.

[0057] By introducing the protective gas into the first pipe 110, the inner surface of the first pipe 110 is in the protective atmosphere, and the inner surface of the first pipe 110 is not easy to be oxidized during subsequent welding, and the welding quality is higher.

[0058] Specifically, the protective gas can be nitrogen, carbon dioxide or inert gas.

[0059] Specifically, the base 200 is also usually provided with a cavity 230 and an air inlet hole 240, and the air outlet hole 220 and the air inlet hole 240 are both in communication with the cavity 230. The air inlet hole 240 is used to introduce the protective gas into the cavity 230, and after the protective gas enters the cavity 230, the air pressure can be more stable, so that the air outlet hole 220 can discharge the protective gas with stable air pressure.

[0060] Referring to Figure 2 In some embodiments of the present application, the second end 112 is insertedly connected with the third end 121, and the limiting member 320 includes a supporting rod 321 for supporting the fourth end 122.

[0061] By insertingly connecting the second end 112 with the third end 121, the position of the second pipe 120 can be preliminarily limited, and by supporting the fourth end 122 through the supporting rod 321, the probability of the second pipe 120 shaking due to its own gravity can be effectively reduced, so that the second pipe 120 can be effectively limited at a set position.

[0062] Specifically, the fourth end 122 of the second pipe 120 is bent, and at this time, the bent part of the fourth end 122 can be supported by the supporting rod 321.

[0063] Referring to Figure 2 In the improved scheme of the above embodiment, the position of the supporting rod 321 relative to the base 200 in the up-down direction is adjustable, and the supporting rod 321 can rotate around the vertical axis.

[0064] By adjusting the position of the supporting rod 321 relative to the base 200 in the up-down direction, the second pipe 120 of different heights can be supported. By rotating the supporting rod 321 around the vertical axis, the target part of the second pipe 120 can be supported by the supporting rod 321. In summary, by adjusting the position of the supporting rod 321, the supporting rod 321 can support different types of second pipes 120, and the compatibility of the welding jig is stronger.

[0065] Specifically, the welding jig further includes a column 330 and a column fixing clamp 310, and the supporting rod 321 is fixed to the column 330 through the column fixing clamp 310. When it is necessary to adjust the position of the supporting rod 321 relative to the base 200 in the up-down direction, or to rotate the supporting rod 321 around the vertical axis, by loosening the bolts on the column fixing clamp 310, the supporting rod 321 can be moved up and down and rotated.

[0066] In another embodiment, the column 330 is provided with a plurality of through holes in the up-down direction, each of which is in communication with a threaded hole. One end of the support rod 321 is inserted into a certain through hole and locked by a first set screw threaded with the corresponding threaded hole. By removing the first set screw, the position of the support rod 321 relative to the base 200 in the up-down direction can be adjusted by inserting the support rod 321 into a different through hole and locking the first set screw threaded with the corresponding threaded hole. The lower end of the column 330 is inserted into the box body 600 and locked by a second set screw. By loosening the second set screw, the support rod 321 can be rotated around the vertical axis.

[0067] In some embodiments of the present application, the limiting member 320 includes a clamping jaw for clamping or releasing the fourth end 122.

[0068] By clamping the fourth end 122 with the clamping jaw, the second pipe 120 can also be conveniently limited to the second set position.

[0069] Specifically, the clamping jaw can be a finger air cylinder or an electric manipulator.

[0070] Referring to Figure 4 In some embodiments of the present application, the welding jig further includes a lifting assembly 400 for adjusting the position of the base 200 in the up-down direction.

[0071] By adjusting the position of the base 200 in the up-down direction, the position of the first pipe 110 in the up-down direction can be adjusted, and the contact position of the second end 112 and the third end 121 can be adjusted, thereby facilitating the welding of the second end 112 and the third end 121.

[0072] Specifically, the lifting assembly 400 can be one of an air cylinder, an oil cylinder, an electric cylinder, a linear motor, a gear rack mechanism driven by a motor, a chain wheel and chain mechanism driven by a motor, a synchronous pulley and synchronous belt mechanism driven by a motor, and a crank slider mechanism driven by a motor.

[0073] Referring to Figure 4 According to the welding device of the second aspect of the present application, the welding device includes a welding jig and a welding device 500 for welding the second end 112 and the third end 121.

[0074] According to the welding device of the present application, at least the following beneficial effects are achieved: by using the above-mentioned welding jig, the installation of two pipes (such as copper pipes) can be conveniently and quickly completed, thereby facilitating the improvement of the welding efficiency of the pipes.

[0075] Specifically, the welding device 500 can be one of a resistance welding device, a high-frequency induction welding device, and a laser welding device.

[0076] The embodiments of the present application are described in detail above with reference to the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present application. Furthermore, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
