They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0031] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 4 illustrate.

[0032] This application provides an automatic gas-inlet welding device (hereinafter referred to as welding device), which can clamp the workpiece for welding; at the same time, it can automatically fill the workpiece with protective gas during welding, so that the weld joint of the workpiece can be protected by protective gas in time, thereby improving the welding quality and reducing the need for manual labor, thereby improving work efficiency.

[0033] Specifically, such as Figure 1 , Figure 2 As shown, the welding equipment includes a clamping mechanism 1 and an air inlet mechanism 2. The clamping mechanism 1 has a clamping hole for inserting a workpiece. One end of the clamping mechanism 1 has multiple grippers arranged around the outer periphery of the clamping hole and capable of radial displacement to clamp workpieces of different diameters. The end of the air inlet mechanism 2 furthest from the workpiece is the air inlet end, which is connected to a gas device to provide protective gas. The end of the air inlet mechanism 2 closest to the workpiece is the air outlet end, thereby guiding the protective gas to the workpiece. During welding, the protective gas... It can act promptly to ensure welding quality; the air intake mechanism 2 is set in the clamping hole and has an air intake channel, which is coaxial with the clamping hole; the radial end of the air intake mechanism 2 is connected to the inner wall of the clamping hole to achieve relative fixation between the air intake mechanism 2 and the clamping mechanism 1, ensuring the working stability of the air intake mechanism 2, and eliminating the need for manual holding of the air intake mechanism 2, and ensuring continuous automatic air intake during the welding process, thereby reducing labor costs, improving work efficiency, and reducing the probability of manual contact with the welding area, thus improving the safety factor.

[0034] Furthermore, such as Figure 1 , Figure 2As shown, the welding equipment also includes a rotating mechanism 3 and a mounting bracket 4. The mounting bracket 4 has a space for mounting the rotating mechanism 3. The clamping mechanism 1 is connected to the axial end face of the mounting bracket 4. The rotating mechanism 3 passes through the mounting bracket 4 and is connected to the clamping mechanism 1 to drive the clamping mechanism 1 to rotate around the axis of the clamping hole, so that the workpiece can rotate to achieve circumferential welding. The mounting bracket 4 and the rotating mechanism 3 are provided with through holes that are coaxial with the clamping hole. The air intake mechanism 2 is located in both the through hole and the clamping hole.

[0035] Among them, such as Figures 2 to 4 As shown, the air intake mechanism 2 includes an air guide 24 and at least one connector. The two ends of the air guide 24 are respectively connected to two connectors to achieve connection with different gas pipelines. The connector is connected to both the air guide 24 and the clamping mechanism 1, thereby achieving the connection between the air guide 24 and the clamping mechanism 1, which can ensure the synchronous rotation of the air intake mechanism 2 and the clamping mechanism 1, thus ensuring the stability of air intake.

[0036] like Figure 2 As shown, the mounting bracket 4 includes a first mounting plate 41, a second mounting plate 42, and a mounting sleeve 43. The mounting sleeve 43 has a multi-faceted annular structure. The first mounting plate 41 and the second mounting plate 42 are located on opposite axial sides of the mounting sleeve 43, and are fixedly connected to the mounting sleeve 43. The first mounting plate 41 is connected to the clamping mechanism 1. The rotating mechanism 3 includes a transmission component 31 and a driving component 32. The transmission component 31 is located within the cavity of the mounting bracket 4. The second mounting plate 42 has a through hole, through which the driving end of the driving component 32 passes and connects to the transmission component 31. One end of the transmission component 31 is connected to the driving component 32, and the other end passes through the first mounting plate 41 and connects to the clamping mechanism 1, thereby achieving rotational drive of the clamping mechanism 1. In this embodiment, the transmission component 31 is a gear, and the transmission principle is existing technology, which will not be described in detail here.

[0037] Specifically, such as Figure 3 , Figure 4 As shown, the outlet end of the air guide 24 is connected to the first connector 25, and the inlet end of the air guide 24 is connected to the second connector 26. The air guide 24, the first connector 25, and the second connector 26 are all provided with axially penetrating gas channels for supplying protective gas channels.

[0038] Furthermore, such as Figures 3 to 4As shown, the air intake mechanism 2 includes a first connecting member 21, a second connecting member 22, and a third connecting member 23. The first connecting member 21 is used to connect the air guide member 24 or the first connector 25 to the clamping mechanism 1. The second connecting member 22 is used to connect the second connector 26 to the second mounting plate 42. The third connecting member 23 is used to achieve a rotatable connection between the air guide member 24 and the second connecting member 22. That is, one end of the air guide member 24 is relatively fixedly connected to the clamping mechanism 1 through the first connecting member 21, and the other end is rotatably connected to the second mounting plate 42 through the cooperation of the third connecting member 23 and the second connecting member 22. As a result, when the rotating mechanism 3 drives the clamping mechanism 1 to rotate, the air guide member 24 can rotate with the clamping mechanism 1, and both ends of the air guide member 24 can be supported to ensure the working stability of the air intake mechanism 2.

[0039] Specifically, such as Figures 2 to 4 As shown, the intake mechanism 2 also includes a mounting base 27, which is a cylindrical structure. The mounting base 27 is disposed between the second connector 22 and the third connector 23. The two axial ends of the mounting base 27 are connected to the second connector 22 and the third connector 23, respectively. The mounting base 27 is also sleeved on the outside of the second connector 26 and the air guide 24. The mounting base 27 is fixedly connected to the second connector 26, that is, the inner wall of the mounting base 27 is tightly fitted with the outer wall of the second connector 26, and there is a gap between the inner wall of the mounting base 27 and the outer wall of the air guide 24.

[0040] Among them, such as Figure 4 As shown, the mounting base 27 includes a fixing part 271, a sealing part 272, and a mounting part 273. The fixing part 271 and the sealing part 272 are arranged axially. Both the fixing part 271 and the sealing part 272 are through-hole structures. The axes of the fixing part 271 and the sealing part 272 are on the same straight line. The diameter of the hole in the fixing part 271 is smaller than the diameter of the hole in the sealing part 272. In this application, the air intake mechanism 2 is provided with a sealing component 28. The sealing component 28 is disposed in the sealing part 272 of the mounting base 27 and is sleeved on the air guide. On component 24, the inner wall surface of the sealing assembly 28 is in contact with the outer wall surface of the air guide 24, the outer wall surface of the sealing assembly 28 is in contact with the inner wall surface of the sealing part 272, and the sealing assembly 28 is axially limited within the sealing part 272. The side of the sealing assembly 28 near the second connector 26 is tightly in contact with the axial sidewall of the sealing part 272, so that the sealing assembly 28 wraps the second connector 26 and the outside of the air guide 24, thereby achieving a seal at the connection between the second connector 26 and the air guide 24 and preventing gas leakage.

[0041] like Figure 3 , Figure 4As shown, the mounting base 27 is connected to the second connector 22 and the third connector 23. The mounting portion 273 consists of multiple through holes parallel to the axial direction penetrating the mounting base 27. These through holes are arranged along the same circumference, and the mounting portion 273 is arranged around the outer periphery of the sealing portion 272, wherein the mounting portion 273 and the sealing portion 272 are not in communication. Correspondingly, the second connector 22 has a first connecting hole 222, which penetrates the second connector 22 parallel to the axial direction and is coaxially arranged with the mounting portion 273. Figure 4 As shown, the third connector 23 is provided with a third mounting hole 233, which is coaxially arranged with the mounting part 273. The third mounting hole 233 is a blind hole. The mounting part 273, the first connecting hole 222, and the limiting blind hole are coaxially arranged to allow the same connector such as a bolt or screw to be inserted, so as to realize the axial connection of the second connector 22, the mounting base 27 and the third connector 23.

[0042] Among them, such as Figure 4 As shown, the air guide 24 is provided with a first connecting portion 241 and a second connecting portion 242. Both the first connecting portion 241 and the second connecting portion 242 are formed by the outer wall surface of the air guide 24. The first connecting portion 241 and the second connecting portion 242 are arranged sequentially along the air intake direction. The outer contours of the first connecting portion 241 and the second connecting portion 242 are both annular, and the outer diameters of the first connecting portion 241 and the second connecting portion 242 are both smaller than the outer diameter of the air guide 24 body. The outer diameter of the first connecting portion 241 is smaller than the outer diameter of the second connecting portion 242. The outer diameter of the first connecting portion 241 is smaller than the outer diameter of the sealing portion 272 of the mounting base 27, thereby forming an annular space between the sealing portion 272 of the mounting base 27 and the first connecting portion 241 of the air guide 24 for mounting the sealing assembly 28.

[0043] like Figure 4 As shown, the second connecting part 242 is used to install the third connecting member 23. The third connecting member 23 is sleeved on the second connecting part 242 of the air guide member 24. A limiting step is formed between the end of the second connecting part 242 away from the first connecting part 241 and the body of the air guide member 24 to limit the third connecting member 23 axially. At the same time, an annular limiting ring is provided at the end of the second connecting part 242 near the first connecting part 241 to limit the end of the third connecting member 23 near the mounting base 27 axially, so as to ensure the connection stability between the third connecting member 23 and the air guide member 24.

[0044] like Figure 4As shown, a limiting step is formed at the connection between the first connecting part 241 and the second connecting part 242 of the air guide 24, and a limiting step is formed at the connection between the fixing part 271 and the sealing part 272 of the mounting base 27. The two limiting steps are located on both sides of the sealing assembly 28, thereby limiting the axial sides of the sealing assembly 28 to ensure the installation stability of the sealing assembly 28, making the sealing assembly 28 less prone to misalignment, thus ensuring the sealing effect.

[0045] In this embodiment, the sealing component 28 is a cylindrical structure, which is sleeved on the first connecting part 241 of the air guide 24; the sealing component 28 includes two symmetrically arranged lip seals, and the sealing principle of the lip seals is the same as that of the prior art, which will not be described in detail here.

[0046] Furthermore, the first connector 21 will be described in more detail; such as Figures 2 to 4 As shown, the first connector 21 is a plate-shaped structure. The center of the first connector 21 is provided with a first mounting hole 211. The air guide 24 passes through the first mounting hole 211, and the outer wall surface of the air guide 24 is adapted to the inner wall surface of the first mounting hole 211 to achieve a stable connection between the first connector 21 and the air guide 24. The radial ends of the first connector 21 are set as arc-shaped structures that fit with the inner wall surface of the clamping hole, and the upper and lower ends are provided with protruding mounting protrusions. The mounting protrusions are provided with radially penetrating through holes. The inner wall surface of the clamping hole is also provided with corresponding through holes for the insertion of the same connector such as bolts or screws, thereby realizing the connection between the first connector 21 and the clamping mechanism 1, and then realizing the connection between the clamping mechanism 1 and the air intake mechanism 2.

[0047] Among them, such as Figure 3 , Figure 4 As shown, the air guide 24 is also provided with a third connecting part 243. The third connecting part 243 is located near the air outlet end of the air guide 24. The first mounting hole 211 of the first connecting part 21 is sleeved on the third connecting part 243. The inner wall surface of the first mounting hole 211 is in contact with the outer wall surface of the third connecting part 243 to achieve a tight connection between the first connecting part 21 and the air guide 24. The third connecting part 243 includes at least one mounting plane 2431 and at least one mounting curved surface 2432. In the combination of the mounting plane 2431 and the mounting curved surface 2432, the mounting plane 2431 provides a limiting function in the circumferential direction, so that the connection between the air guide 24 and the first connecting part 21 is circumferentially limited, so that the first connecting part 21 and the air guide 24 will not rotate relative to each other, ensuring the stability of the air guide 24 relative to the clamping mechanism 1.

[0048] Furthermore, the second connector 22 is described in more detail; such as Figure 2 , Figure 3As shown, the second connector 22 is a plate-shaped structure. The center of the second connector 22 is provided with a second mounting hole 221. The second mounting hole 221 is sleeved on the outer periphery of the fixing part 271 of the mounting base 27 to realize the radial limiting connection between the second connector 22 and the mounting base 27. The outer periphery of the second mounting hole 221 is provided with a plurality of first connecting holes 222. The second connector 22 is axially connected to the mounting shaft through the first connecting holes 222. The radial end of the second connector 22 is provided with a second connecting hole 223. There are a plurality of second connecting holes 223. The second connecting holes 223 are parallel to the axial direction and pass through the second connector 22. Correspondingly, the second mounting plate 42 of the mounting bracket 4 is provided with a blind hole corresponding to the second connecting hole 223. The blind hole is coaxially arranged with the second connecting hole 223 to allow the same connector such as bolts or screws to be inserted to realize the connection between the second connector 22 and the mounting bracket 4. This makes the second connector 26 and the mounting base 27 fixedly connected to the mounting bracket 4, ensuring the support stability of the air intake end of the air intake mechanism 2.

[0049] Furthermore, the third connector 23 is described in more detail; such as Figure 4 As shown, the third connecting member 23 includes a bearing 231 and a mounting cylinder 232. The bearing 231 is sleeved on the second connecting part 242 of the air guide member 24, and the bearing 231 and the second connecting part 242 are tightly fitted together. The mounting cylinder 232 is sleeved on the outside of the bearing 231, and the inner wall surface of the mounting cylinder 232 is tightly fitted with the outer wall surface of the bearing 231. The mounting cylinder 232 can not only connect the bearing 231 to the mounting seat 27 and the second connecting member 22, but also protect the outside of the bearing 231. The third mounting hole 233 is provided on the mounting cylinder 232.

[0050] In this embodiment, the mounting cylinder 232 is rotatably connected to the air guide 24 via the bearing 231, and the mounting base 27, the second connector 26, and the second connecting member 22 are rotatably connected relative to the air guide 24. When the rotating mechanism 3 drives the clamping mechanism 1 to rotate, the air guide 24 rotates with the clamping mechanism 1, while the second connecting member 22, the second connector 26, the mounting base 27, the sealing assembly 28, and the mounting cylinder 232 do not rotate. The sealing assembly 28 can ensure sealing when the air guide 24 rotates relative to the second connector 26.

[0051] It should be noted that in this application, the two ends of the air guide 24 are detachably connected to the first connector 25 and the second connector 26 respectively, so that the air intake end and the air outlet end of the air intake mechanism 2 can be replaced with connectors of different specifications to increase the compatibility range of the air intake mechanism 2.

[0052] And, as Figure 3 , Figure 4As shown, both the first connector 25 and the second connector 26 are provided with multiple annular protrusions, and the cross-section of the annular protrusions is a conical structure, which can increase the sealing effect of the pipe joints connected to them and prevent air leakage.

[0053] Among them, such as Figure 4 As shown, the outlet end of the air guide 24 is provided with a fourth connecting part 244. The fourth connecting part 244 is located in the gas channel of the air guide 24. The fourth connecting part 244 is a through hole, and the diameter of the fourth connecting part 244 is larger than the diameter of the gas channel. The fourth connecting part 244 is used to install the first connector 25. The outer wall surface of the air inlet end of the first connector 25 is tightly fitted with the inner wall surface of the fourth connecting part 244 to realize the connection between the first connector 25 and the air guide 24.

[0054] It should be noted that the various embodiments of this application can be arbitrarily combined into new embodiments, provided that the solutions do not conflict and the technical solutions can coexist.
