[0032] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0033] An embodiment of the utility model provides a welding assembly for use on a welding unit, which includes a C-shaped supporting plate 1. When welding a pipe fitting, the pipe fitting is inserted into the C-shaped supporting plate 1. The pipe fitting to be welded is coaxial with the C-shaped supporting plate 1, and the pipe fitting is welded through the welding assembly of the C-shaped supporting plate 1.

[0034] like Figure 1 and Figure 2 As shown, the welding assembly includes a swing controller 4, a welding component 6, an arc voltage controller 2, a guide component 5 and a connecting plate 3.

[0035] The welding assembly includes a guide component 5 and a connecting plate 3, wherein the guide component 5 is arranged on a C-shaped bearing plate. The guide component 5 includes a guide rail and a slider (not shown in the figure), the slider can move along the guide rail or the guide rail moves along the slider, and the second end of the connecting plate 3 is connected to the slider or the guide rail in the guide component 5.

[0036] One of the swing controller 4 and the arc voltage controller 2 is fixed on the C-shaped carrier plate 1 and connected to the first end of the connecting plate 3, and can drive the connecting plate 3 and the slider in the guide component 5 to move along the guide rail respectively.

[0037] Of course, in some other embodiments, the slider and the guide rail in the guide component 5 can be interchanged, that is, the slider is fixed on the C-shaped bearing plate 1, and the second end of the connecting plate 3 is fixedly connected to the guide rail in the guide component 5.

[0038] The swing controller 4 and the other of the arc voltage controllers 2 are connected to the welding component 6 and are fixed together on the second end of the connecting plate 3, and can move with the connecting plate 3 to make the welding component 6 approach the center of the C-shaped supporting plate 1 or away from the center of the C-shaped supporting plate 1.

[0039] The welding component 6 mainly includes a welding gun, a cable and other components. The welding component 6 is mainly used for welding the pipes passing through the C-shaped bearing plate 1. The specific structure belongs to the prior art and will not be described in detail.

[0040] The welding assembly of this embodiment separates the arc voltage controller 2 from the swing controller 4 by adding a connecting plate 3 and a guide component 5. The connecting plate 3 between the arc voltage controller 2 and the swing controller 4 is placed on a slider or a guide rail in the guide component 5. Part of the torque applied by the welding component 6 can be applied to the C-shaped supporting plate 1 through the guide component 5. Such a layout structure improves the stress condition and the torque borne by the arc voltage controller 2 and the swing controller 4, and improves their service life and reliability.

[0041] It should be noted that the specific structures of the swing controller 4, welding component 6 and arc voltage controller 2 of this embodiment do not fall within the scope of protection of this application, and the specific structures can refer to other currently disclosed patent documents, journals, academic papers and other prior arts. These prior arts all have detailed introductions to the structures, working principles, etc., which will not be repeated in this embodiment.

[0042] Embodiment 1:

[0043] like Figure 1 and Figure 2 As shown, in this embodiment, the arc voltage controller 2 is fixed on the C-shaped carrier plate 1, and a sliding driving component is provided on the arc voltage controller 2. The sliding driving component is provided by the arc voltage controller 2 itself, and mainly includes a sliding component and a driving component for driving the sliding component to move. The first end of the connecting plate 3 is connected to the sliding component on the sliding driving component, so that the sliding driving component on the arc voltage controller 2 can drive the connecting plate 3 and the sliding component of the guide component 5 to move along the guide rail of the guide component 5.

[0044] The welding component 6 is fixed on the swing controller 4 and can move with the swing controller 4. The swing controller 4 is fixed on the second end of the connecting plate 3 and can move with the slider of the guide component 5 to make the welding component 6 close to the center of the C-shaped supporting plate 1 or away from the center of the C-shaped supporting plate 1.

[0045] In some embodiments, Figure 1 and Figure 2As shown, the swing controller 4, the arc voltage controller 2, the welding component 6, the connecting plate 3 and the guide component 5 are respectively arranged on the same surface of the C-shaped supporting plate 1, so as to facilitate the layout of these components.

[0046] Of course, in some other embodiments, the swing controller 4, the arc voltage controller 2, the welding component 6, the connecting plate 3 and the guide component 5 do not need to be arranged on the same surface. The specific positions can be determined according to the specific working conditions.

[0047] In some embodiments, the sliding driving component on the arc voltage controller 2 is connected to the first end of the connecting plate 3, and the slider in the guide component 5 and the swing controller 4 are respectively connected to the second end of the connecting plate 3.

[0048] It should be noted that the sliding driving component on the arc voltage controller 2 is carried by the controller itself. Therefore, the first end of the connecting plate 3 is connected to the sliding member on the arc voltage controller 2, so that the connecting plate 3 can be controlled to move.

[0049] Preferably, the moving direction of the sliding member in the sliding driving component on the arc voltage controller 2 is consistent with the extending direction of the guide rail in the guide component 5 .

[0050] Furthermore, if Figure 3 As shown, in some embodiments, the connecting plate 3 mainly includes a main body portion 30 in an elongated shape, a first connecting portion 31 located at a first end of the main body portion 30 , and a second connecting portion 32 located at a second end of the main body portion 30 .

[0051] The first connection portion 31 forms a first end of the connection plate 3 and is used to connect the sliding member on the arc voltage controller 2. The second connection portion 32 forms a second end of the connection plate 3 and is used to connect the slider in the guide component 5 and the swing controller 4.

[0052] The first connection portion 31 and the second connection portion 32 on the connection plate 3 are respectively located on the same side of the main body 30 along the length direction thereof.

[0053] In this embodiment, a hollow area 33 is provided on the main body 30 , which can appropriately reduce the weight of the entire connecting plate 3 .

[0054] Of course, the structure of the connecting plate 3 in the above embodiment is only exemplary, and the specific structure of the connecting plate 3 can be determined according to factors such as the relative position and placement of the arc voltage controller 2 and the swing controller 4.

[0055] In some embodiments, the slider in the guide member 5 and the swing controller 4 are located on opposite sides of the connecting plate 3 at the second end of the connecting plate 3. That is, the slider in the guide member 5 is connected to the first surface of the connecting plate 3, and the swing controller 4 is connected to the second surface of the connecting plate 3.

[0056] Further, the welding component 6 is located on a first side of the extending direction of the guide rail in the guide component 5 , and the arc voltage controller 2 is located on a second side of the extending direction of the guide rail in the guide component 5 .

[0057] The welding component 6 is brought closer to the swing controller 4 by the connecting plate 3 , so that the torque applied by the welding component 6 to the swing controller 4 during operation can be directly transmitted to the C-shaped supporting plate 1 through the slider and the guide rail in the guide component 5 to be borne.

[0058] like Figure 1 and Figure 2 As shown, the welding member 6 of this embodiment moves along the radial direction of the C-shaped carrier plate 1 to approach the center of the C-shaped carrier plate 1 or move away from the center of the C-shaped carrier plate 1 .

[0059] The extending direction of the guide rail in the guide component 5 is consistent with the moving direction of the welding component 6 , so that the welding component 6 can be driven to move along the radial direction of the C-shaped bearing plate 1 by the movement of the slider.

[0060] Taking the exemplary welding assembly structure in FIG. 1 as an example, the guide rail in the guide component 5 extends in the vertical direction and is located in the left half of the C-shaped carrier plate 1, and the connecting plate 3 and the arc voltage controller 2 are both on the left side of the guide component 5. When the connecting plate 3 moves in the vertical direction, the welding component 6 is simultaneously driven to move in the vertical direction to weld the pipe fittings passing through the C-shaped carrier plate 1.

[0061] The guide component 5 , the connecting plate 3 and the arc voltage controller 2 of this embodiment may also all be located in the right half of the C-shaped supporting plate 1 .

[0062] In addition, the guide rail structure of the guide component 5 in this embodiment is not specifically limited.

[0063] Meanwhile, the positions of the guide rail and the slider in the guide component 5 of this embodiment can be replaced, that is, the slider in the guide component 5 is fixed on the C-shaped bearing plate 1 , and the second end of the connecting plate 3 is connected to the guide rail in the guide component 5 .

[0064] Embodiment 2:

[0065] Different from the first embodiment, the swing controller 4 and the arc voltage controller 2 of this embodiment are mutually replaced. That is, the swing controller 4 is fixed on the C-shaped carrier plate 1 , and the sliding driving component on the swing controller 4 is connected to the first end of the connecting plate 3 .

[0066] The arc voltage controller 2 is connected to the welding component 6 and fixed to the second end of the connecting plate 3 .

[0067] It should be noted that the movement direction of the sliding member in the sliding driving component on the swing controller 4 is different from the movement direction of the sliding member in the sliding driving component of the arc voltage controller 2 .

[0068] The moving direction of the sliding member in the sliding driving component of the arc voltage controller 2 is parallel to the plate surface of the C-shaped carrier plate 1 , while the moving direction of the sliding member in the sliding driving component of the swing controller 4 is perpendicular to the plate surface of the C-shaped carrier plate 1 .

[0069] Therefore, in the second embodiment, the guide rail in the guide component 5 is arranged in a direction perpendicular to the surface of the C-shaped supporting plate 1, and the swing controller 4 can control the arc voltage controller 2 and the welding component 6 to move in a direction perpendicular to the surface of the C-shaped supporting plate 1.

[0070] The embodiment of the utility model further provides a welding unit, such as a full-position automatic TIG welding unit. The welding unit comprises a C-shaped carrier plate 1 and a welding assembly as described in any one of the above embodiments.

[0071] The above description is intended to be illustrative rather than restrictive, and those skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present disclosure. Moreover, the above examples (or one or more of them) may be used in combination with each other, and it is contemplated that these embodiments may be combined with each other in various combinations or permutations.
