[0047] Four or more work areas are arranged at equal intervals in the circumferential direction of the annular table 11. A pair of closed plates 20 are fixedly installed on each work area. A pair of L-shaped cover plates 21 and a pair of side plates 22 are arranged between the two closed plates 20. Third electric telescopic rods 25 are fixedly installed on the two closed plates 20. The movable ends of the two third electric telescopic rods 25 are fixedly connected with the two L-shaped cover plates 21 respectively. The two side plates 22 are fixedly installed on the annular table 11.

[0048] The L-shaped cover plate 21 and the inner side of the side plate 22 are provided with a pair of first clamping plates 23 and a pair of second clamping plates 26, each of the closed plates 20 is fixedly installed with a first electric telescopic rod 24, the movable end of the first electric telescopic rod 24 is fixedly connected with the first clamping plate 23, the first electric telescopic rod 24 penetrates the inside of the L-shaped cover plate 21 and is in sliding connection with the L-shaped cover plate 21; each of the side plates 22 is fixedly installed with a second electric telescopic rod 27, the movable end of the second electric telescopic rod 27 is fixedly connected with the second clamping plate 26;

[0049] The staff places the cavity coupler cleaned by the cleaning agent in the working area, and then the movable ends of the first electric telescopic rods 24 and the second electric telescopic rods 27 are extended, and the two first clamping plates 23 and the two second clamping plates 26 jointly clamp and fix the cavity coupler;

[0050] The upper surface of the workbench 10 is fixedly installed with a closed cover 30, the inside of the closed cover 30 covers two working areas, one of which is a flushing area and the other of which is a drying area, the closed cover 30 is fixedly installed with a drying piece 31 at the drying area, the drying piece 31 can be provided as an infrared drying lamp; the top ends of the closed plates 20 are at the same height as the inner top surface of the closed cover 30, and when the two closed plates 20 completely enter the inside of the closed cover 30, the two closed plates 20 and the inner surface of the closed cover 30 form a closed cavity;

[0051] The rack is installed with a vacuumizing assembly, the vacuumizing assembly is in communication with the flushing area; the rack is installed with a flushing assembly, the flushing assembly can flush the cavity coupler in the flushing area; the rack is also installed with an argon gas conveying assembly, the inside of the shell 14 is fixedly installed with an argon gas tank 13, the argon gas conveying assembly is in communication with the inside of the argon gas tank 13, and the argon gas conveying assembly can convey argon gas into the flushing area;

[0052] The annular table 11 first conveys the cavity coupler cleaned by the cleaning agent into the flushing area, at this time, the vacuumizing assembly pumps out the air in the closed cavity formed between the two closed plates 20 and the closed cover 30, then the flushing assembly works to spray water on the cavity coupler, after the cavity coupler is flushed, the argon gas conveying assembly conveys argon gas into the closed cavity to protect the cavity coupler by using the argon gas;

[0053] The lower surface of each work area is fixedly installed with a vertical pipe 72, the annular table 11 is provided with a through hole 111 at each work area, the bottom end of the plurality of vertical pipes 72 is fixedly installed with a rotating ring 71, the rotating ring 71 is rotatably installed on a water storage assembly, the water storage assembly is fixedly installed with a water outlet pipe 76, the water outlet pipe 76 is fixedly installed with a fifth electric control valve 761, one of the vertical pipes 72 is fixedly installed with a liquid level controller 73, and water in the flushing process of the cavity coupler flows into the vertical pipe 72 through the through hole 111. Due to the liquid level controller 73, the liquid level in the vertical pipe 72 is higher than the bottom end of the vertical pipe 72 and lower than the top end of the vertical pipe 72, so that air cannot flow between the plurality of vertical pipes 72, and each closed cavity can maintain a sealed state.

[0054] When the cavity coupler is welded, the staff places the cavity couplers on the work area one by one, and then the two first clamping plates 23 and the two second clamping plates 26 jointly clamp and fix the cavity coupler. The annular table 11 rotates to convey the work area to the flushing area of the closed cover 30. The vacuumizing assembly extracts air in the closed cavity. Thereafter, the flushing assembly flushes the cavity coupler. After the argon gas conveying assembly conveys the argon gas into the closed cavity, the annular table 11 continues to rotate to convey the work area to the drying area. The cavity coupler is dried by using the drying piece 31. Before the work area leaves the drying area, the movable ends of the two third electric telescopic rods 25 are extended, so that the two L-shaped cover plates 21 relatively move. After the two L-shaped cover plates 21 contact and merge, a sealed space is formed between the two L-shaped cover plates 21 and the inner sides of the two side plates 22, and the cavity coupler that has been dried is located in the sealed space. The annular table 11 rotates to move the work area directly below the argon arc welding gun. During the process that the work area leaves the inside of the closed cover 30 and moves to the position directly below the argon arc welding gun, the cavity coupler is always in the state of being protected by argon gas and cannot be oxidized by contacting air. When the argon arc welding gun operates, the movable ends of the two third electric telescopic rods 25 are retracted, so that the argon arc welding gun can perform welding. Therefore, the cavity coupler does not contact air during the period from flushing to welding, so that the welding quality can be guaranteed to be high. In addition, the argon arc welding device can continuously perform welding, and the welding efficiency is also high. Embodiment

[0055] The flushing assembly comprises a water pump 40, a first outer pipe 41 and a water spraying head 43. The water pump 40 is fixedly installed on the lower surface of the workbench 10.

The water spraying head 43 is fixedly installed on the end portion of the first inner pipe 42. The upper surface of the closed cover 30 and the position of the flushing area are fixedly installed with a fixed cavity block 301. The fixed cavity block 301 is fixedly installed with a fourth electric telescopic rod 44. The movable end of the fourth electric telescopic rod 44 is fixedly connected with the first inner pipe 42.

[0056] The water pump 40 delivers water into the first outer pipe 41, which is finally sprayed on the cavity coupler by the water spraying head 43. During the flushing process, the fourth electric telescopic rod 44 can drive the water spraying head 43 to reciprocate in the length direction of the fixed cavity block 301, thereby increasing the flushing range of the water spraying head 43 and improving the flushing effect on the cavity coupler.

[0057] The argon gas delivery assembly includes a gas delivery pump 50, a first connecting pipe 51, a second outer pipe 52, and a gas spraying head 54. The gas delivery pump 50 is fixedly installed on the lower surface of the workbench 10. One end of the first connecting pipe 51 is fixedly connected with the argon gas tank 13, and the other end of the first connecting pipe 51 is fixedly connected with the gas inlet end of the gas delivery pump 50. One end of the second outer pipe 52 is fixedly connected with the gas outlet end of the gas delivery pump 50, and the other end of the second outer pipe 52 is slidingly installed with a second inner pipe 53.

[0058] Not only can the argon gas be delivered into the closed cavity, but also the gas spraying head 54 can make the argon gas sprayed on the cavity coupler, so that the water can quickly separate from the cavity coupler, and the residual water on the cavity coupler can be reduced, thereby reducing the drying time.

[0059] The vacuum pumping assembly includes a gas pumping pump 60, a connecting pipe group, and a gas outlet pipe 63. The gas pumping pump 60 is fixedly installed on the lower surface of the workbench 10. One end of the connecting pipe group is fixedly connected with the gas pumping end of the gas pumping pump 60, and the other end of the connecting pipe group is in communication with the flushing area. The gas outlet pipe 63 is fixedly installed on the gas outlet end of the gas pumping pump 60.

[0060] The connecting pipe group is composed of a U-shaped pipe 61 and a communication pipe 62. Both ends of the U-shaped pipe 61 in the length direction are fixedly connected with the closed cover 30. One end of the U-shaped pipe 61 is in communication with the flushing area, and the other end of the U-shaped pipe 61 is in communication with the drying area.

The third electric control valve 631 is fixedly installed on the gas outlet pipe 63. The gas outlet head 66 is fixedly installed on the other end of the delivery pipe group, and the gas outlet head 66 is arranged directly below the argon arc welding gun.

[0062] The cavity coupler after welding has high temperature at the welding seam, and is easy to react with oxygen in the air, thereby affecting the quality of argon arc welding. Before the dried cavity coupler leaves the drying area, the closed cavity still has a large amount of argon. After the two L-shaped cover plates 21 are combined, the first electric control valve 611 and the third electric control valve 631 are closed, and the second electric control valve 612 and the fourth electric control valve 641 are opened. At this time, the argon in the closed cavity can be extracted by the exhaust pump 60, and the argon is sprayed on the welding seam of the cavity coupler just after welding by the gas outlet head 66. Not only can the cooling of the welding seam be accelerated, but the argon can also protect the welding seam, thereby further ensuring the quality of welding.

[0063] The water storage assembly includes an annular groove plate 70, a liquid storage box 74, and a second connecting pipe 75. The annular groove plate 70 is rotationally connected with the rotating ring 71. The second connecting pipe 75 is fixedly installed between the annular groove plate 70 and the liquid storage box 74.

[0064] The conveying pipe group is composed of a first conveying pipe 64 and a second conveying pipe 65. A first main pipe 642 is fixedly installed on one end of the first conveying pipe 64. A second main pipe 651 is fixedly installed on one end of the second conveying pipe 65.

The plurality of branch pipes 67 penetrate through the inside of the liquid storage box 74 and are fixedly connected with the liquid storage box 74.

[0065] The argon extracted by the exhaust pump 60 is located in the drying area. The extracted argon has a high temperature. The argon needs to pass through the plurality of branch pipes 67. The plurality of branch pipes 67 will be in contact with the water stored in the liquid storage box 74, thereby being able to cool the argon. The cooled argon is in contact with the welding seam, thereby being able to accelerate the cooling speed of the welding seam. Not only can the quality of argon arc welding be improved, but the argon can also be more fully utilized.
