[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The features of the terms "first" and "second" in the specification and claims of the utility model may explicitly or implicitly include one or more of the features. In the description of the utility model, unless otherwise specified, the meaning of "plurality" is two or more.

[0025] Combine the following Figure 1-Figure 4 The utility model describes an airway structure and an airway system based on a turret.

[0026] like Figure 1 As shown, an embodiment of the utility model provides an airway structure based on a turret, including: a gas flow portion, an air inlet pipe 123, a slip ring 10 and a plurality of first pipes 13. The gas flow portion has a first surface and a second surface relative to each other, and the first surface is provided with an air inlet groove body. The first end of the air inlet pipe 123 is connected to the gas injection machine, and the second end of the air inlet pipe 123 passes through the second surface and is connected to the air inlet groove body. The slip ring 10 is stacked below the first surface, and the slip ring 10 can rotate with the turret 30. The slip ring 10 is provided with a plurality of air inlet holes 101 in a ring shape. When the air inlet hole 101 is opposite to the air inlet groove body, the air inlet hole 101 is connected to the air inlet groove body. Each air inlet hole 101 is connected to a first pipe 13.

[0027] Specifically, the turret 30 includes a mover and a stator, and the slip ring 10 is connected to the mover. When the mover rotates, it can drive the slip ring 10 to rotate together. The gas flow part is connected to the stator. When the turret 30 rotates, the gas flow part does not rotate. The first surface of the gas flow part is provided with an air intake groove body. In this embodiment, the air intake groove body is an arc-shaped groove section, that is, the air intake groove body has only one section, and it does not form an annular groove body. The air intake groove body is located at the welding station. The air intake groove body is connected to the gas injection machine through the air intake pipe 123 to inject the protective gas from the gas injection machine into the air intake groove body. When the slip ring 10 rotates, it drives each first pipeline 13 to rotate. When the first pipeline 13 is opposite to the air intake groove body, the protective gas enters the opposite first pipeline 13 from the air intake groove body. This part of the first pipeline 13 has protective gas, while the remaining first pipelines 13 that are not opposite to the air intake groove body have no protective gas. The first pipeline 13 is connected to the welding head 40 , so that when the collecting plate is welded, the welding head 40 located at the welding station sprays out the shielding gas, while the welding head 40 not located at the welding station does not spray out the shielding gas.

[0028] Furthermore, in the present embodiment, the number of the air intake pipe 123 may be one or more. When the number of the air intake pipe 123 is one, in order to ensure the air intake amount, the diameter of the air intake pipe 123 should be larger, and at this time, the width of the air intake groove body should also be wider; and when the number of the air intake pipe 123 is more than one, the diameter of the air intake pipe 123 may be smaller, and correspondingly, the width of the air intake groove body may also be narrower.

[0029] In this embodiment, the protective gas is nitrogen.

[0030] The turret-based airway structure provided by the embodiment of the utility model has a gas flow portion and a slip ring, and an air intake groove body is provided on the surface where the gas flow portion and the slip ring are stacked. When the slip ring rotates, the protective gas can only enter the first pipeline connected to the air intake groove body, so that the protective gas is only sprayed at the welding station, thereby avoiding energy waste and reducing production costs.

[0031] like Figure 1 and Figure 2 As shown, in the embodiment of the utility model, the gas flow part includes a sealing plate 11 and an air inlet cover 12. The sealing plate 11 is arranged above the slip ring 10. The sealing plate 11 is provided with a first air inlet groove 111 that runs through its thickness. The first air inlet groove 111 is an arc-shaped groove section. The air inlet cover 12 is arranged above the sealing plate 11. The surface where the air inlet cover 12 and the sealing plate 11 are stacked is provided with a second air inlet groove 121. The second air inlet groove 121 is opposite to the first air inlet groove 111 to form an air inlet groove body. A plurality of air inlet pipes 123 are arranged on the air inlet cover 12. The air inlet pipes 123 are connected to the second air inlet groove 121 and the first air inlet groove 111.

[0032] Specifically, the surface on which the sealing plate 11 and the slip ring 10 overlap is the first surface of the gas flow portion, and the first air inlet groove 111 is a through groove that penetrates the thickness of the sealing plate 11. Each first pipe 13 is inserted into an air inlet hole 101, and the end face of the first pipe 13 is located in the air inlet hole 101, or is flush with the surface on which the slip ring 10 and the sealing plate 11 overlap, so as to avoid interference between the first pipe 13 and the sealing plate 11 when the slip ring 10 rotates. The surface on which the air inlet cover 12 and the sealing plate 11 overlap is provided with a second air inlet groove 121, and the second air inlet groove 121 is opposite to the first air inlet groove 111 to form an air inlet groove body. In this embodiment, the arc length of the second air inlet groove 121 may be equal to that of the first air inlet groove 111, or may be greater than that of the first air inlet groove 111. The surface of the air inlet cover 12 facing away from the sealing plate 11 is the second surface of the gas flow portion, which is provided with a plurality of air inlet pipes 123, which are opposite to the first air inlet groove 111 to ensure that each air inlet pipe 123 is connected to the air inlet groove body. When the slip ring 10 rotates, the protective gas enters the air inlet groove body from the gas injection machine and the air inlet pipe 123, and then enters the first pipeline 13 connected to the air inlet groove body.

[0033] Furthermore, to facilitate processing, in this embodiment, the second air inlet groove 121 is an annular groove.

[0034] like Figure 3 and Figure 4 As shown, in an embodiment of the utility model, the airway structure based on the turret further includes a vacuum pumping mechanism and a plurality of second pipes 21, and the vacuum pumping mechanism is connected to the negative pressure machine. A vacuum pumping groove body is also provided on the first surface of the gas flow portion, and the vacuum pumping groove body is connected to the vacuum pumping mechanism. The slip ring 10 is provided with a plurality of vacuum holes 102 in an annular shape, and each vacuum hole 102 is connected to a second pipe 21. When the vacuum hole 102 is opposite to the vacuum pumping groove body, the vacuum hole 102 is connected to the vacuum pumping groove body, wherein the vacuum pumping groove body is an arc-shaped groove segment.

[0035] Specifically, if Figure 4As shown, the slip ring 10 is provided with not only a circle of air inlet holes 101 but also a circle of air exhaust holes 102. The air inlet holes 101 can be arranged close to the turret 30, or the air exhaust holes 102 can be arranged close to the turret 30. The air inlet slot body of the gas flow part is arranged opposite to the air inlet hole 101, and the air exhaust slot body of the gas flow part is arranged opposite to the air exhaust hole 102. In this embodiment, the air exhaust slot body is also an arc-shaped slot segment, that is, the air exhaust slot body does not form an annular slot body, that is, at a certain position, no negative pressure is formed in the second pipe 21. Specifically, when the slip ring 10 rotates, it drives the second pipe 21 to rotate, and the negative pressure machine extracts the gas in the second pipe 21 opposite to the air exhaust slot body through the vacuum mechanism, so that negative pressure is generated in this part of the second pipe 21 to adsorb the collecting plate.

[0036] In this embodiment, after the collecting plate is welded, no negative pressure is formed in the second pipe 21, that is, the gas flow portion is located in a circular arc behind the welding station without a gas extraction groove.

[0037] like Figure 1 As shown, the sealing plate 11 is provided with a first air extraction groove 112 running through the thickness thereof, and the surface where the air inlet cover 12 and the sealing plate 11 are stacked is provided with a second air extraction groove 122 , which is opposite to the first air extraction groove 112 to form an air extraction groove body.

[0038] Specifically, in this embodiment, the first air extraction groove 112 is a circular arc groove segment, and the second air extraction groove 122 is an annular groove. When the sealing plate 11 and the air inlet cover 12 are stacked, the portion in communication between the first air extraction groove 112 and the second air extraction groove 122 forms an air extraction groove body. When the slip ring 10 rotates, the negative pressure machine extracts the air in the second pipe 21 in communication with the first air extraction groove 112, so that negative pressure is formed in this portion of the second pipe 21 to absorb the collecting plate.

[0039] Furthermore, if Figure 2 As shown, in this embodiment, the first air extraction groove 112 is an arc-shaped groove segment, and the sealing plate 11 is not provided with the first air extraction groove 112 on a section of the arc behind the welding station, and the second air extraction groove 122 is a circular ring groove, and the air extraction groove formed by the two is also an arc-shaped segment groove. At the same time, the arc length of the first air extraction groove 112 is greater than the arc length of the first air inlet groove 111, that is, in this embodiment, the vacuuming position is more than the shielding gas ejection position, and the vacuuming is stopped only after the welding is completed, and the shielding gas is only injected during welding.

[0040] Furthermore, a partial arc section of the first gas extraction slot 112 is parallel to the first gas inlet slot 111, that is, at the welding station, the injection of protective gas and the vacuuming are performed simultaneously.

[0041] like Figure 3As shown, in an embodiment of the utility model, the vacuum pumping mechanism includes: a main pipeline 20 and a plurality of branch pipelines, the main pipeline 20 is arranged at the center of the gas flow portion, the main pipeline 20 is connected to the negative pressure machine, the first end of each branch pipeline is connected to the main pipeline 20, and the second end of each branch pipeline is connected to the vacuum tank body.

[0042] Specifically, when the slip ring 10 rotates, the gas in the second pipe 21 opposite to the vacuum tank body passes through the vacuum tank body, the branch pipe, and the main pipe 20, and is extracted by the negative pressure machine, so that negative pressure is formed in this part of the second pipe 21 to adsorb the collecting plate.

[0043] like Figure 3 and Figure 4 As shown, the embodiment of the utility model also provides an airway system based on a turret, including: a turret 30, an airway structure, a gas injection machine, an air pump and a plurality of welding pressure heads 40. The turret 30 includes a mover and a stator, the gas flow portion of the airway structure is connected to the stator, and the slip ring 10 of the airway structure is connected to the mover. The gas injection machine and the air pump are both connected to the gas flow portion. A plurality of welding pressure heads 40 are annularly arranged on the outer wall of the mover, and each welding pressure head 40 is connected to a first pipe 13 and a second pipe 21.

[0044] Specifically, the gas injection machine and the gas extraction machine are arranged outside the turret 30, and a plurality of welding pressure heads 40 are arranged in an annular manner on the outer wall of the mover. Each welding pressure head 40 is respectively connected to a first pipe 13 and a second pipe 21. The welding pressure head 40 is provided with an inlet flow channel and an exhaust flow channel. The inlet flow channel is connected to the first pipe 13, and the exhaust flow channel is connected to the second pipe 21. When the mover rotates, the welding pressure head 40, the first pipe 13, the second pipe 21 and the slip ring 10 rotate simultaneously. The negative pressure machine extracts the gas in the second pipe 21 connected to the exhaust tank body, so that a negative pressure is generated in the welding pressure head 40 connected to the part of the second pipe 21 to adsorb the collecting plate. The turret 30 continues to rotate. When the turret 30 rotates to the welding station, the collecting plate is still in the adsorption state. At this time, the first pipe 13 located at the welding station is connected to the inlet tank body, and the gas injection machine injects protective gas into this part of the first pipe 13, and the protective gas is ejected by the welding pressure head 40 connected to the part of the first pipe 13. After welding is completed, the turret 30 continues to rotate. When the first pipe 13 and the second pipe 21 are opposite to the part of the gas flow portion where the air inlet groove and the air exhaust groove are not provided, negative pressure is not formed in the first pipe 13, and protective gas is not injected into the second pipe 21. At this time, the welding head 40 no longer adsorbs the collecting plate and does not spray out protective gas to avoid energy waste.

[0045] The turret-based airway system provided by the embodiment of the utility model can spray out protective gas during welding by setting up an airway structure. After welding is completed, the gas in the welding pressure head is neither extracted nor injected into the welding pressure head, thereby realizing scientific gas supply, avoiding energy waste and reducing production costs.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
